The two black Labradors were panting heavily on the bed. Leon gazed down at Caleb as he idly rubbed his back--on every inhale and exhale, the younger lab's ribs expanded and contracted under Leon's hands. Leon's stomach rested on his son's rump, and he could feel Caleb tiredly wag his tail; it slowly and lightly lapped against his legs and waist while Leon stayed on his knees behind him. Caleb, with his tongue hanging out of his mouth, glanced back at Leon.

"Do...do you think you've softened up enough?" Caleb asked as he caught his breath.

Leon grinned. "One way to find out. Scoot up, kiddo."

Caleb's heart fluttered at the order. He swallowed and steadied himself on his hands and knees, then began to lean forward for leverage. He felt the pressure grow in his ass as his father's knot tugged back against his rectum.

"Oh fuck," Leon panted--the movement and pressure on his still sensitive knot was just enough to make his cock pulse again and push one last thin stream of cum into his son's ass. "There's some more pups for you," he chuckled.

Caleb relaxed back against Leon, sinking his butt against his dad's hips again, and shook his head. "Think it's still going to take a little while."

"In that case, might as well get comfy." Leon leaned forward and scooped an arm under Caleb's chest--he then drew the younger lab back against him as they both fell sideways onto the mattress, ending with Leon spooning his son. Caleb tangled his legs with his father's and snuggled back against him, reveling in the embrace with of an arm tight around him and Leon's larger stomach nestled against his back. He sighed, content, and rested his head in the crook of his father's arm.

"Settled?" Leon asked, looking down at Caleb with a soft smile.

"Uh-huh."

Leon used his free hand to ruffle the top of Caleb's head. "Atta boy. Wanna order some takeout or just relax for a while?"

"Think I'm still full from you feeding me a few loads earlier," Caleb chuckled. "I'm good to just chill for now. Could maybe go for some cheesecake later, though. 'Specially if I'm eating for two...or six, considering how much you knocked me up."

"You need to stop." Leon smirked.

"Wha--you're the one who started it!"

"I don't think so."

"Uh-huh, right." Caleb sounded thoroughly unconvinced.

"Oh, and what's that supposed to mean?"

Caleb muttered something into his father's arm.

"What was that?" Leon leaned in closer, his ear above Caleb's mouth.

"It's not my fault you want grandkids so soon, old man," Caleb repeated loudly, grinning.

"Caleb James Parker, you stop that, you stop that now!" Leon yelped. He then grimaced as he felt Caleb clench down on his cock. "Ohh..." Leon stopped himself and scowled down at his laughing son before settling back on the pillow behind him. "I'm not that old," he continued.

"51, you're getting up there," Caleb countered playfully. He unclenched his ass to let Leon's knot deflate further.

"Keep it up, young man, see what happens."

"Oh what, you gonna spank me again?"

"Worse."

Caleb's ears perked up.

"I'll withhold spanking."

The younger lab looked back at his father, his eyebrows raised. Leon nodded down at him, his expression serious. Caleb paused, choosing his next words carefully.

"You don't have the balls to do that."

Leon instinctively raised a hand, ready to strike exposed rump space.

"Aha, see!" Caleb pointed at his hand. Leon held still as Caleb continued, "It's too natural for you! You have the balls to do a lot, but withholding spanking or some other punishment? You physically can't do it."

Leon's serious face broke as he barked in laughter and dropped his hand to his son's chest, hugging him closer to himself. "You're being bratty tonight, boy," he crooned in Caleb's ear.

"You like it though," Caleb responded softly, snuggling back further into the embrace.

"That, and other things," Leon conceded.

"Oh, what other things? Somebody been doing some more exploring?" Caleb asked.

"Here and there," Leon said vaguely.

Caleb looked back at his father. "Well, now you've got me curious. Where exactly?"

Leon yawned and shook his head, but he could see the excited spark in Caleb's eye. "Oh no, you're not gonna get me with that look again," he chuckled.

"What look?" Caleb, grinning now, kept looking at him with the same spark.

"That look where you..."

"Yes?" Caleb's grin grew wider, and, if possible, the spark in his eye grew brighter.

Leon sighed. "Want to know how corrupted I've gotten."

Caleb's eyes were on fire and he wore a full shit-eating grin.

Leon recognized that he'd lost the battle as soon as he'd started. "Oh fine, lemme get my phone."

He looked back at the bedside table behind him, but he saw his phone wasn't lying on the charger pad.

"Oh...Opal, ping my phone," he called out for the home assistant system.

A faint ping echoed from the en suite bathroom.

"Well, look who's using more technology," Caleb observed sarcastically.

"Oh stop it. Wanna get your old man his phone?"

"If you can help me off of here." Caleb wagged his butt against Leon's waist--he could feel his father's cock start to slip little by little.

"Comin' right up," Leon grunted. Keeping his arms tightly wrapped around his son's chest, Leon rolled on his back, with Caleb on top of him. He released his embrace, letting Caleb sit up and squat over his father, with Leon's cock--now being tugged upwards by Caleb's ass--being the only thing connecting them. Caleb tensed his legs, pulling Leon's cock up enough to show the root straining against his sheath, and the tight pleasure made Leon's breath catch.

Caleb heard his father rub his hands together behind his back, and then...

SMACK.

The loudness, sting, and force of Leon's spank made the younger lab jump enough to lose his footing and topple off of his father. Leon groaned from the sting on his hand and the sensory overload on his cock as it popped wetly out of his son's puckered and abused hole, and a small splash of cum from Leon's ass landed on the older lab's stomach. Caleb landed ass-up with his face down in the sheets by Leon's feet and his legs splayed on either side of Leon's stomach.

"Looks like that helped," Leon chuckled.

"Yeah, thanks, Dad." Caleb's deadpan voice was muffled by the bedsheets. He took a deep breath and pushed himself up, then he crawled to the edge of the bed, swung his legs off, and stood. As Caleb walked to the bathroom, he raised his tail and widened his gait to give Leon an unobstructed view of his gaping hole. Leon whistled low and watched his son disappear beyond the bathroom door.

When Caleb reappeared, Leon saw that his cock had softened up enough to retreat further into his cum-stained sheath, and he watched his son's balls sway as he returned to bed. Caleb crawled up next to his father and handed over the phone he'd picked up from the bathroom counter, then laid on his stomach while he watched Leon type his passcode.

"So, what have you been finding?" Caleb asked as he embedded himself further against Leon's side.

"Well, a friend of a friend told me about this app," Leon began, navigating on his phone's screen to an app folder. "It's basically another one of those hookup apps, but this one is for people who want to..."

"Indulge in a taste of the wild side'," Caleb read the tagline on the splash screen for the app Leon had just opened. "Tastr? Sounds like a food app."

"Well, there are some people on here who want that," Leon told him.

"What, you mean feeding? Or to actually be someone's food, like vore?"

"Both," Leon smirked.

Caleb's eyebrows rose. "Well, wouldn't have thought you'd be on an app like that. Getting hungry for someone?"

"Oh, not specifically, and there are lots of other filters to choose from," Leon explained evasively. He scrolled idly through the profiles page, showing thumbnails of men in the area, many of them clearly wearing leather or rubber fetish gear. "I've got them pre-set to show guys with similar interests."

"And what filters do you have, pray tell?"

"Ah, ah, ah." Leon wagged a finger in front of Caleb's nose. "That's staying secret, gotta keep a few surprises in store for you now, don't I?"

"Tease," Caleb sulked.

Leon laughed and licked his son's cheek. "Well, since you were a good boy tonight, I can maybe let you in on one or two things. Would you like that?"

Caleb nodded excitedly.

Leon opened a menu and selected the small picture in the upper right corner--when the next screen opened with a larger view of the same picture on it, Caleb saw that it was a photo of the two of them from their trip to Great Sand Dunes National Park. In fact, it was the selfie he'd taken when they were both shirtless, with Leon's arm tightly around Caleb's shoulders, and Caleb licking his father's cheek while he held his phone with his free hand. Then he read the profile tagline Leon had written: "Lab Dad and Son For Fun".

It started to click into place. "Wait, is this..."

"A joint account? Technically, yes." Leon grinned down at his son's happy smile. "I thought we might want to look at getting into some group fun, or at least start with a threesome. Just so proud of my boy, I want to share you with others."

"I love it!" Caleb's tail wagged enthusiastically as his eyes skimmed over more of the profile Leon had set up for them. "When did you do this?"

"It's just been a little side project to work on here and there," Leon shrugged, still grinning. "You really like it? This is something you'd want to do?"

"With you? Absolutely!"

Caleb raised his chin with his tongue out, and Leon picked up the signal immediately--he leaned down and kissed Caleb, sliding his tongue in and tasting his son's mouth, licking across his teeth, and swabbing towards the entrance to his throat. He heard Caleb moan softly and pulled back again, licking his chops.

"You're so good at that, always got me wanting more," Caleb murmured.

"That's not me, that's your 20-year-old libido talking." Leon winked.

"Maybe," Caleb conceded. He looked back at the screen that still showed the profile Leon had created for them, then frowned. "Wait, you said 'technically' this was a joint account. Why technically?"

"Ah, because even though it's for both of us, you're not getting access to this one," Leon answered.

"What?"

"All communications on here are going through me," Leon explained. When Caleb started to protest, he continued, "Cal, there are some truly weird characters on here. I'd rather they know that you're spoken for immediately before you get caught up in something we're both gonna regret. You can call it me being overprotective, that's fine, but if I catch you on here with your own account, I'm booting you off the phone plan. We're either in this together or not at all."

Leon watched his son, hoping to see that he understood how serious he was.

Caleb grinned.

"That was a good speech, although you really didn't have to go for the 'we're in this together or not at all'," he mocked before leaning in against Leon's side again. "Message received, loud and clear."

Leon sighed and ruffled the top of Caleb's head again. "Alright, alright, sorry I had to go Dad Mode there."

"Hey, I get it, plus you needed an excuse to vicariously lust over me through talking with all the other guys who want a piece."

"Oh, they can have a piece, but they gotta give it back, this is all mine," Leon said as he reached down and roughly groped Caleb's bubble butt. He wriggled it in his father's grip and Leon lightly spanked it before returning to look at his phone.

"So, any bites on there so far?"

"Funny you should ask, I've gotten quite a few saying they want to bite on you." Leon navigated to his conversations and pulled up a profile from one of the latest messages. "Including Phil Mason down the street."

Caleb's head rose and he looked at his father. "You're kidding."

"See for yourself."

Leon turned the screen so Caleb could see the older, scantily-clad rabbit in a highly compromising position.

"Oh my god."

"Seems he and his son like to get up to a lot of fun, too," Leon continued.

Caleb spluttered. "Seth? Isn't he still in high school?"

"Where have you been? He just started at the community college. Bet those two have been really going at it, Phil's got some kinky filters tagged," Leon noted, turning the phone back to himself to focus on his neighbor's profile.

"I wanna see!"

"Oh no, we'll save that for later," Leon said. "If you run into Seth, maybe you can surprise him by asking. Now then," he continued, shuffling down in the bed and rolling to straddle Caleb's side, so his head was behind his son's and his arms stretched in front of them both, "I want us to look for something together."

"Oh, I like this activity," Caleb said, adjusting his arms and legs to get more comfortable under his dad's weight. He watched as Leon held the phone in front of both of them so he could get an unobstructed view of all the profiles on the screen. "Any specific searching?"

"I've already got our filters set, so what you see is what you get. Anybody catch your eye?"

"Hm..."

Together, father and son perused the profiles, with Caleb calling out thumbnails and Leon tapping on them to open each user page. Like any other hookup or dating app, the profile descriptions ranged in information from nothing at all to a few sentences to in-depth paragraphs with lists of likes and dislikes. Although as Caleb watched his father scroll through the users in their area, he couldn't help but notice themes in some of the search filters--for example, there were quite a few doms who enjoyed cock and ball torture and watersports. Not that he was one to complain, he'd been trying to get Leon to do more of that to him, so it warmed his heart on some deeply perverted yet loving level that his father was open to exploring that further with him.

Some of the notable profiles they came across included a camel who enjoyed indulging in hypnosis, a pair of alligator twins, a fox who described his passion for flogging and collection of ball gags and restraints in great detail, a bull looking to host an orgy with a room dedicated just to fisting, and a deer who wanted to get double-teamed by a father and son pair. They had chatted with a few bears and a boar who wanted to drench them in piss, but nothing panned out there. Eventually, Leon and Caleb had scrolled through and refreshed the search results enough times that the sun had long descended below the horizon and the two Labradors were lying together in the dark, illuminated only by the LED screen. Caleb looked at the status bar on his father's phone to see the clock read 9:27 PM.

Leon yawned in Caleb's ear. "What do you say we give it a break for tonight? We'll probably have more luck tomorrow."

Caleb nodded and wriggled further under his dad. "And if not tomorrow, then the day after that. We'll find someone eventually." He yawned as well before continuing, "I'm just glad you're up for this, it really means a lot."

Leon shut off his phone and rubbed Caleb's cheek in the dark. "Of course! It makes me glad to see you so excited."

"Oh, and what makes you think I'm excited?"

"Well, your tail was trapped, but I could feel you wagging it as much as you could," Leon responded. "Plus..." he reached with his free hand below Caleb's waist, wedging his hand around the younger canine's cock that had stiffened and was throbbing against the mattress. He squeezed lightly, getting a rise out of his son, and said, "I had a hunch our friend was going to make another appearance."

"Well, you weren't wrong." Caleb twisted himself around so he laid on his back under his dad. In the dim light from the open window of their bedroom, he looked up into the older man's eyes, watching and grinning up at him. Leon couldn't help but smile down at his son before lowering his head so his muzzle met Caleb's. They connected, their tongues pressing against each other, and Leon's arms folded Caleb into another tight embrace.

---

It took another four days before Caleb got the message at work. He had just finished an inventory check for the bakery when he felt his phone vibrate in his pocket. He fished his phone out and sat down on one of the empty crates before pulling up the text message from Leon.

"Great news, I found someone for us! Think you might like him."

The phone buzzed again in Caleb's hand as he received a series of pictures. The first was a screenshot of a profile featuring a large, muscled tiger with a wide smile and gold gages in his ears. Caleb read the tagline and description:

Let me use you

Fit and fun Daddy looking for a couple boys to call my own, or at least enjoy a romp in bed with and see if something grows from there. Also love being the dom for an actual dad and son--where are all the naughty parents and kids? But before we get too far, when I say "gent on the streets, wild in the sheets", I mean wiiiiiild.

Got a wide range of interests, happy to talk more about them. Yes, I'm a tiger. Yes, I bite (when asked). Other things I do when asked include training you to get up to your limits and past them--I can only do so much, you have to be willing to put in the work when you hand yourself over to Daddy.

The following three photos Caleb received were additional pictures that the tiger had taken: one where he held a riding crop and wore a pair of tight black shorts and an executioner's cowl, another of him reclining nude next to a swimming pool, and a third of his large cock halfway inside a dalmatian's rear. As Caleb perused the photos, he couldn't help but feel a certain stirring in his shorts. He checked his surroundings to make sure he was alone in the storeroom, then laid a hand on his crotch and applied pressure on his cock as it began to emerge from his sheath. Caleb looked over the tiger's profile screenshot again: he was 40 years old and looked like he kept himself in very good shape, and some of the fetishes he had tagged were cbt, electro, feet, domination/submission, hypnosis, and torture. Caleb couldn't help but lick his lips.

"What do you think?" Leon's message appeared under the pictures.

Caleb texted back immediately. "I like him! Chatted with him yet?"

"Been talking this whole afternoon, we've really hit it off."

"Seems like he'd be a good fit?"

"A great fit! He's really interested in you, too."

Caleb was about to text back, but he saw Leon was still typing, so he waited instead.

"Want to meet us after work? I'm getting a beer with him right now, we can wait for you to join us."

Caleb's eyebrows rose as he considered the offer. "Possibly, where are you two?"

"Oscar's."

Caleb checked the time--his shift would be over in 30 minutes, and Oscar's, the bar his dad had noted, was two blocks down from the bakery. "Sounds great! Be there in 45."

It was an agonizing half hour to wait for his day at the bakery to end. Caleb tried to distract himself by doing the most menial tasks: sweeping the floors again and again, washing mixing bowls and spatulas, and wiping down the workstations. And every time he looked up at the clock, he felt his stomach flip with excitement and nerves to think about what he was waiting for. Yet it was tempered by the disappointment of seeing that only five minutes had elapsed ever so slowly...then another five...and another five...and another five...

He worked on prepping baking sheets, he checked the freezer and oven temperatures, he dried the items in the dishwasher and took to putting them away, all while thinking of his dad talking with this tiger about...

Caleb jumped when he felt a hand pat him on the back. He turned as his coworker, Gavin, said, "Sorry, sorry! Got a late start, I should have let you know--you can get out of here."

"Jeez you got me good there," Caleb said. He shook his head to himself and looked up at the clock--his shift had ended 10 minutes ago. "Oh shit, I've gotta run."

"You alright?" the raccoon asked. "Sorry again for being late, my sister needed--"

"No worries!" Caleb called as he scrambled out of his apron and grabbed his backpack off the back hallway rack. On his way out, he quickly punched his timecard, then pushed through the door, rushed down the alley to the main street, and high-tailed it to Oscar's. He'd have liked to have some extra time to brush the flour off his clothes and make sure he looked a little more presentable, but with Gavin late, it didn't leave him much room to dawdle--nervous as he was, Caleb was excited to meet the man his dad had found, and he didn't want to make him wait much longer.

When Caleb got to Oscar's, he stopped in front of the door and took a few calming breaths--his stomach had flipped a couple more times on the way and he could feel the anticipation tensing every part of his body. After a few moments, he stopped panting, his nervous tail wagging was light and relaxed, and he put his hand on the door handle. Then, with one more steadying breath, he pushed.

When Caleb stepped into the bar, he looked around at the tables and booths, searching for...

"Caleb! Over here!" A deep and honeyed voice called while an orange and white arm with black stripes waved at Caleb from the corner next to the pinball machine--Caleb looked to see Leon turning around in his seat and join the tiger in waving at him.

Caleb scooted past one of the tables in his way and stopped at the booth. He looked down at the tiger--he wore a white t-shirt and looked fairly similar to his profile picture. It was obvious that under the shirt, his shoulders were wide and muscled, his ample pecs were well defined, his thick biceps stretched his sleeves; the smile he wore looked even more full of teeth, which Caleb couldn't help but appreciate. He smiled and nodded at the tiger, who had been looking back up at him with clear interest in his eyes as he appraised the younger Labrador.

"There you are, I was just about to text if this time was still good for you," Leon said, also looking up at Caleb.

"Sorry, my coworker was a little late, I only just got off my shift."

"No worries at all," the tiger said. "It's great to meet you, Caleb." He proffered a firm, meaty hand.

"This is Kassam," Leon said as Caleb took the tiger's hand.

"G-great to meet you, too, Kassam," Caleb couldn't help but trip over the first word as his hand was engulfed in the tiger's.

Kassam winked at him and, still holding his hand, addressed Leon. "You were right--just like you, but even cuter." He released Caleb's hand and asked, "What are you having?"

"Having?"

"To drink, it's my treat," the tiger explained.

"Oh! I'm still underage, so I'm good."

"What, no fake ID?"

"I try to keep out of trouble for my dad," Caleb chuckled.

"He's a very good boy," Leon added with a smile.

"I don't doubt that for a minute," Kassam purred. "Can I at least get you a soda or something?"

"Oh! Um, root beer, please." Caleb didn't mean to, but it came out sounding like a question he meekly wanted to ask the large man, instead of a drink request.

"One root beer, coming up," Kassam said with a smile. He stood from his seat; Caleb noticed just how tall he was, and the tiger patted Caleb heavily on the shoulder on his way to the bar. Caleb gawked for a second, watching the tiger's tail swing with his gait, before looking back down at his dad. Leon winked up at him and scooted to his right, making room for Caleb next to him. Caleb sat and placed his backpack on the ground.

"So..." he began.

"So?" Leon reached for his beer, a hazy IPA.

"What's his deal?" Caleb asked.

Leon took a gulp and paused. "Well, he seems really nice to me. Genuine. And upfront about what he's looking for."

"And that is..."

"Us. For fun. Just friends with benefits," Leon filled in. "He understands how we are and isn't looking to join the family or anything. But he wants to help us explore more and broaden our horizons. Show us more of the ropes."

"His ropes in particular?"

"They're on his agenda, yes."

Caleb smirked. "But he doesn't want to be..."

"What? Your other dad? Oh no, we already talked about romance and all that--we're very much on the same page. He knows you're all mine."

Caleb nodded, approving. "That's good. Although based on what you sent me and what I'm seeing now, I'm pretty sure I want to be his at least for a little while."

Leon took another sip of his beer and grinned. "I showed him your ass pictures and his exact words were 'I have big plans for that boy's hole. Poor thing is going to be a quivering wreck begging for more.'"

Caleb smiled and watched the tiger pick up the foamy root beer and a dark beer from the bartender. "Music to my ears!"

"Ask him anything you want, he's answered all my questions and seems to me that he knows what he's doing," Leon added as Kassam began walking back towards them.

"How long have you two been talking?"

"Since last night, after you went to sleep," Leon answered. "But it was my decision to hold off on telling you anything until this afternoon after we'd talked some more."

Kassam arrived at the booth and gently placed Caleb's drink in front of him. "One root beer for you, and another stout for me," he announced as he slid into his seat opposite the Labrador father and son. He raised his glass. "Cheers!"

Caleb and Leon raised theirs and clinked them against Kassam's before everyone took a drink. As Caleb lowered his glass back to the table, he felt something brush against his lower leg. He subtly shifted his foot away from it, thinking his dad wanted to play a little footsie with him, but he didn't want to be distracted when Kassam began, "So, your dad tells me you're quite the kinky little fucker in bed."

Caleb snorted and laughed, not expecting that opening.

The tiger grinned. "Hey, there we go, bud. It was either that, or I ask you about your job, but your old man's already told me about that, too."

"Well, I have to give you points for originality," Caleb replied, rubbing his face as he settled in his seat against Leon; his father reached his left arm to wrap around Caleb's shoulders, pulling him further into his large stomach. "Sounds like Dad's told you a lot already."

Kassam nodded. "And I like what I hear. And I very much like what I see!"

The thing under the table brushed against Caleb's lower leg, this time more forcefully. From the shape and angle it was coming from, Caleb realized it was Kassam's tail twitching up against him. The young Labrador grinned at the tiger as he shifted his leg against the tail, reciprocating the attention. "But before we get too far along, is there anything you want to know about me?" Kassam continued before taking another sip of his beer.

"Well, starting off with the basics..."

Kassam smiled to himself. "My job, hobbies, all that shit? Good place to start. I'm in applied chemical research, development, and engineering. Basically I get to work in a lab all day doing chemistry, although it's nothing special or exciting. That's been my life for the past 15 years, ever since I moved here."

"Where from?" Caleb asked.

"Florida panhandle, tiny little place you wouldn't know. It's way off in the middle of nowhere and right next to the beach. I was part of a research team studying ocean chemistry, that was right after I finished my degree," Kassam supplied. "They kept me busy, and so does this job I'm in now."

"You look like you've found time for the gym though," Caleb observed.

"Nice segue into my hobbies there," Kassam chuckled. "Yes, gym time is very important to me; I really enjoy being outdoors and active, too. And I do enjoy building my own DIY gizmos and gadgets, I like to tinker with machinery and software and get my hands into different things in my home workshop. So sometimes I feel like a mad scientist inventor, but it's all pretty tame."

"You're not building a robot or anything?"

"Oh no, that's out of my wheelhouse, and not much interested in robotics myself."

"And that doesn't feel too much like work to you?" Caleb asked. "You're in a lab all day, then you do stuff in your own workshop?"

Kassam shrugged. "It's different kinds of work; most of the chemistry at work is up on the whiteboards and computers and research journals, and the mechanical and software stuff at home is something I can mess around with in my hands. When I don't have my hands in or on someone else, that is."

Caleb smiled as he felt the tiger's tail curl comfortably around his ankle under the table.

The Labradors and the tiger continued their discussion, which was mostly Caleb asking about Kassam's additional interests--such as recent shows and movies he had watched and his favorite books and songs--and history. Kassam did ask Caleb a few questions about his relationship with his father, which Leon helped answer when appropriate. The glasses on the table were emptied down thirsty throats and refilled by Kassam again and again, and before the trio knew it, two and a half hours had passed. Even though Caleb was only drinking root beer, he could feel the loosened energy flowing between Leon and Kassam--he noticed how the two of them eyed him hungrily every so often, how Kassam licked his lips when looking at Leon, how his dad's tail wagged more and more under the table, and how Kassam had traded his own tail around Caleb's ankle for a foot shamelessly stroking up and down his calf. Kassam drained his glass and sighed before speaking.

"So, we might want to start talking about how we want to play," he said. "Does this weekend work for you two?"

Caleb felt his heart thump a little heavier in his chest. He briefly glanced up at his dad before addressing Kassam. "Well, I'm off work, so I'd be down for this weekend."

Leon nodded before resting his chin on top of his son's head. "That's good with me, too. Did you have anything specific in mind?"

The tiger, resting his elbow on the table, traced a finger around the rim of his glass as he contemplated it for a moment, then said, "I might have an idea, if you're up for it."

He looked up at the Labradors--Leon and Caleb watched him intently. Kassam chuckled and continued, "Leon, I'm thinking maybe you come over to my place on your own first--I've got a lot of toys I'd like to use on you solo and see how much you can take. Then let's have Cal come over and use them on you for a while before I use them on him and you watch."

Both father and son smiled and started wagging their tails in unison, thumping them against the booth seat.

"I take it you like that idea," Kassam stated. "After that, we can see where the day takes us."

Caleb nodded excitedly, but he felt his father's hand press down lightly on his shoulder, as if holding him back.

"We might want to double check on ground rules," Leon said with a smile. "My son and I can get pretty wild, but just in case..."

"I hear you there, it's always good to play with people who respect the rules and use a safe word to stop, no questions asked," Kassam noted. "I'll always ask if you want something--do you two have a safe word you like to use?"

"Watermelon," Caleb answered immediately.

Kassam raised an eyebrow and cocked his head, intrigued.

"Neither of us like watermelon," Leon supplied. "Can't stand it, so that's our word."

The tiger smiled. "Then I'll keep 'watermelon' in mind."

---

"You're going over now?" Caleb asked from the shower.

It had been two days since they met Kassam. Two days of talking and planning, with Kassam texting with Leon, who then communicated to Caleb. On the tiger's orders, the two Labradors had locked themselves into the matching chastity cages they had bought a few months ago--the prevented erections strained against the unforgiving metal, but father and son pushed each other to keep going, to resist the urge to take the cages off and drain their sore, full balls into each other. It had turned into a competition between them, trying to see who could drive whom to the breaking point and who could hold out the longest. So far, they had both resolutely kept the cages locked. Granted, there had been a lot of groping and hole play for the last 48 hours.

Caleb's cage felt especially tight today as he rested on his knees on the shower floor and held the blunt nozzle that dribbled water. Leon had dressed in shorts and a blue polo shirt and was consulting his phone--Caleb looked closely at his father's crotch and saw the outline of his cage. The plan was for Leon to bring the keys for both cages to Kassam, who would decide when to unlock them. When Leon left the house, Caleb would be truly dependent on the tiger for release.

"Yep, Kassam just sent his address, I'll forward it on to you," Leon replied. He copied the message into his phone's chat with Caleb and sent it as he asked, "You're still good to come to his place in two hours?"

"I think the better question is going to be if you can hold out for that long on your own, it sounded like he has a lot in mind for you," Caleb quipped before inserting the nozzle in his ass. He leaned forward to relax and let the shower water flow further into him.

"I think you'll be surprised at how much I can take, you've been giving me some good stamina training." Leon watched as his son cleaned himself out. "I'll let you know if things change though. Anything I can get you before I go?"

Caleb felt himself fill to the brim and tugged the tip of the nozzle out of his ass, clenching his hole to keep the water in. "Not that I can think of."

"Alright, then in that case..." Leon leaned down to plant a kiss on Caleb's lips and lightly rub his back before standing up again. "I'll see you in a couple hours."

"Try not to have too much fun without me," Caleb called to his father's back as he retreated from the bathroom. "Love you!"

"Love you, too!"

Caleb stood from his knees and squatted, letting gravity and his muscles push the water back down through his system, and he listened for the sounds of Leon's departure--he heard him walk to the kitchen, the rustle and clinking of keys being removed from the hook next to the door, then the door opening, and the light shake of the house as the door swung shut.

"Opal, play House Hunters," Caleb said.

The voice assistant on his tablet--which was propped on its stand on the bathroom counter--opened the streaming app and began to play the show. Caleb stepped out of the shower and sat on the toilet, flushing himself out while the couple on the show talked about what they wanted for their new house. The sounds of the show faded into white noise for Caleb as he checked what was in the toilet bowl. He sighed to himself: he'd need at least five more flushes to get the water to come out clear.

Time passed as he worked on cleaning himself out and listened to House Hunters (he smirked at every mention of "granite countertops and stainless steel appliances"), and eventually Caleb's mind wandered and imagined the activities that Kassam and his father were getting up to. Maybe the tiger had strapped his father to the bed and was spanking him, giving the older dog a lesson in obedience? Had Leon been blindfolded with his hands tied behind his back and forced onto his knees? Or was he in a sling, getting railed by a fuck machine that Kassam might have, all while the tiger watched or had his own cock down Leon's throat? Caleb's caged cock twitched as he thought about Kassam using an e-stim kit on his father--maybe he'd hooked up Leon's balls and hole to get shocked every time he whimpered about his nipples being tortured in a set of tight clamps. And then what about his cage? Had Kassam released Leon's poor cock yet? Would he be allowed to cum at all while they were alone together, or was Kassam planning to milk Leon's prostate and get him to cum down his own throat, feeding Caleb while the tiger commanded him to swallow every drop of his father's seed?

"Fuck," Caleb muttered. He looked down and saw that the tip of his cock pushed hard against his cage and a couple beads of pre had oozed out.

By this point, an hour had gone by, and Caleb saw that the enema water had come out clear for the last two flushes--he was clean enough for a long play session. He checked his phone--he saw the message from Leon containing Kassam's address, which he looked up on his map app. Kassam was three and a half miles away, which meant Caleb would need about thirty minutes to run over there as part of the plan. So, he still had a half hour to kill.

Caleb took his time disconnecting the enema nozzle from the shower, hanging the connecting tube so the excess water could drain from it, and putting the nozzle in the dishwasher. He drank two glasses of water, then went back to the bedroom and stretched--first a knee hug, then a hip flexor stretch. He swung his legs back and forth to open his hips further, stretched his quads, and bent 90 degrees at his waist to stretch his back and legs; he planted his feet as far apart as possible, then reached back with his hands and pulled his cheeks apart--his hole winked in the open air and he shivered lightly in anticipation of what was going to be filling it that afternoon. Caleb checked his smartwatch: he had just enough time to get dressed and start running for Kassam's.

---

"227...229...231," Caleb counted to the house addresses to himself as he jogged down the street. He was dripping in sweat thanks to the heat and humidity he ran through to get here. He stopped the workout on his smartwatch and trudged up the walkway to the front door.

Kassam's house looked like the rest of the small bungalows on the street: small, cozy and updated with white brick, a clean porch, well-maintained lawn, and a peacock blue door with gold trim. Caleb rang the doorbell and waited, panting.

A few moments passed and he heard the door unlock, then it opened to reveal Kassam in a pair of gym shorts and a loose tank top--Caleb's heart fluttered and he could see the muscles rippling clearly under the flesh and fur as the tiger moved.

"Right on time! I was just finishing up with your dad in there," Kassam smiled as he motioned for Caleb to come inside. The lab stepped across the threshold as Kassam placed a large, guiding hand on his back and swung the door shut with his other hand. The tiger steered the dog through the living room--minimally decorated with modern furniture and tasteful art on the walls--to the kitchen, which looked like it would have fit in an IKEA showroom. "Can I get you anything? Water? Juice? A banana?" Kassam asked.

"Water and a banana would be great, thanks," Caleb said.

Kassam opened the fridge and pulled out a pitcher of filtered water, took a glass from the cupboard above, and poured for Caleb. The thirsty lab gulped noisily while the tiger grabbed a banana from the fruit bowl on the white counter and placed it in front of Caleb. He watched as the canine placed the empty glass on the quartz countertop and took up his banana. "How was your run?"

"Good, got my miles in, so I'm happy," Caleb answered between bites. "Hope you like the smell of sweaty dog."

"Oh, very much. Thank you for doing that for me."

Caleb nodded. "How's my dad been?"

"He keeps asking for more, he's certainly keeping me on my toes," Kassam grinned. "But you'll see for yourself soon enough." When Caleb finished his banana, Kassam took the peel from him and deposited it in the trash, then closed the distance between the two of them--suddenly he was right in front of Caleb, his hands resting on the younger man's shoulders, his burning amber and hazel eyes staring into Caleb's.

Caleb was about to speak when the tiger purred quietly, "Don't talk, pup, let Daddy help clean you up."

Keeping one hand on Caleb's shoulder, Kassam placed his other hand on the back of Caleb's head and gripped tightly, then growled low as he pulled to tilt his head back, exposing his neck. Caleb tensed and tried to look down at what Kassam was doing, but it was like his head was in a vise, he couldn't move at all. However, he relaxed when he felt what the tiger did next: Kassam leaned in to sniff Caleb's throat, rubbing his nose in the sweat-matted fur, before opening his mouth and licking with his tongue. Kassam's jaws lightly held Caleb's throat in place as he continued to lick and suck across the dog's windpipe, then his inner neck muscles, and up to the underside of his chin. Caleb moaned at the sensation of the large feline holding and grooming him like this, his tongue digging into his fur, his teeth applying just enough pressure to hold him still, so delicately, so sensually, so...animalistically.

With a loud slurp, Kassam finished his ministrations and straightened up, licking his chops as he forced Caleb to look him in the eye again, and this time Caleb saw the predatory glare in Kassam's gaze: it excited him, being the sole object of the lustful tiger's desire--his heart pounded and his cock strained against the cage.

"You liked that, didn't you, pup." It wasn't a question.

"Yes, Sir," Caleb whispered back.

"Good boy."

With his large hand still strongly cradling the back of Caleb's head, Kassam pushed the Labrador's face forward towards his and met the younger man's muzzle for a deep kiss. Caleb closed his eyes and let his hands wander over Kassam's waist, abs, and pecs, feeling the firm muscle and hard loops that were nipple piercings beneath the tank top. Caleb rested his hand on top of one, then tentatively pulled on it ever so slightly--Kassam growled and pushed his lips further against Caleb's, clearly enjoying the attention to his nipple. The tiger and dog stood in the kitchen like that, moaning softly into each other's mouths, lapping at each other's tongues, nibbling on lips, reaching for tonsils, before Kassam pulled Caleb's head back again and glared at him.

"You taste good, pup."

"So do you," Caleb breathed.

"So do you, what?" Kassam led.

"So do you, Sir," Caleb emphasized.

The tiger grinned. "I'll give you that one, but next time, if you forget to address me properly, you're gonna get punished, understood?"

"Yess, Daddy."

"Good boy." Kassam pushed Caleb into another brief kiss before releasing his grip on his head and using his free hand to grope roughly inside the lab's running shorts. "Very good boy, still wearing your cage. I've got the key, but I'm not going to unlock you just yet. Why don't we go have a little fun before we see what I've gotten your old man to do? Would you like that?"

Caleb nodded enthusiastically.

Keeping his grip on Caleb's cage, Kassam guided the lab by the crotch to a door that led off the kitchen--the tiger pushed it open to show stairs descending to a lit basement. Caleb followed happily as Kassam took them both downstairs and they emerged in the basement landing; it was a small area, with a washer, dryer, and table for laundry to the right and a closed, black door to the left, which they headed for. Caleb watched as Kassam reached into his pocket and pulled out his phone, then held it against the magnetic reader above the doorknob, much like a hotel door; the tumblers clicked as they unlocked, and Kassam pushed through with Caleb behind him.

What Caleb saw was enough to make his jaw drop and his stomach lurch in excitement.

They entered an enormous room with stark, white walls and floors made out of a slightly soft, but still firm, non-porous material; if Caleb had to guess by feel alone, it could have been a rubber floor, but it certainly didn't look like regular black rubber. He noticed drains in the floor every few feet, which made him think that Kassam might hose the floors down after playtime for easy cleanups.

Caleb also had to marvel just at the sheer size of the room--it was likely that Kassam had devoted the majority of his basement space to this one playroom. Towards the front of the room and off to one side, an enormous television screen hung on one of the walls above a small media center, which Caleb guessed that Kassam used to enjoy watching porn--his suspicions were confirmed when he saw the overstuffed leather lounger with plenty of faded stains sitting in front of the TV with a table next to it. There was nothing on the table, but Caleb saw that it had a built-in cabinet, and he had a hunch as to what might be inside.

Wall brackets and hooks placed at different heights adorned the walls, and as Caleb looked up, he saw more brackets and hooks embedded in the ceiling.

The room also contained a corner for an impressive sex sling, three fuck benches with padded leather cushions, a glass and metal display cabinet containing the largest assortment of toys and sexual paraphernalia Caleb had ever seen, and a long, industrial, steel worktable with hooks welded to the edges and legs--straps hung from some of the hooks and there were small puddles of clear liquid still visible on the table. Drawers were also mounted underneath the work surface, and Caleb could only imagine what they might contain.

Another section of the room was dominated by a cluster of eight tall, wide cylinders, each one with a circumference big enough to contain at least two people--the cylinders extended from the floor to the ceiling and looked like they were made out of metal sheeting; Caleb guessed that they might hold some of Kassam's DIY projects that he worked on, or they could be used for storing industrial material--a clear tube connected from the ceiling to the housing for the cylinders. He couldn't be sure what the tube was used for without asking, but he didn't want to break the energy of the scene Kassam had started to set upstairs.

But then, as he continued to survey the room, there was one question that he had to ask.

"Sir, where's my dad?"

Leon was nowhere to be seen.

Caleb turned to see Kassam closed the door behind them and had taken his shirt off and draped it across the back of his easy chair, leaving him wearing only his gym shorts. Caleb also saw that a sizeable tent had formed in the tiger's crotch. Kassam pulled his phone out from his gym shorts and tapped a command: from hidden speakers, smooth low-if music began to play softly, and Caleb started to feel a little more relaxed. Kassam placed his phone on the table next to his easy chair and fixed the young lab in his gaze.

"You'll see him soon, but first I've got just a couple tasks you need to do, pup," the tiger replied. "Why don't you go over to that cabinet with my toys in it."

Obediently, Caleb walked to the display cabinet and stopped in front of it, waiting for an order.

"Get the handcuffs on the third shelf and bring them back to me."

Caleb did as he was told, gently opening the glass door, removing the steel handcuffs from their resting place on the shelf. He closed the cabinet again before taking the cuffs back to Kassam, and he placed them in the tiger's open and expectant paw.

"Good boy," Kassam growled. He swiveled the recliner around so it faced away from the television--when Kassam sat back into it, he faced Caleb and the cluster of cylinders behind him. "Turn around and back up for me, pup. Hands behind your back."

Caleb's pulse quickened despite the relaxing music. He knew what was coming next, and he couldn't stop his tail from wagging as he carried out Kassam's orders.

"What a good puppy, so excited for what Daddy has in store for him," he heard Kassam chuckle--the tiger took his wrists in his hands and, one at a time, locked the handcuffs into place, tight enough to prevent too much movement and loose enough to still be comfortable with just a little bite into Caleb's wrists. Kassam then settled back into his seat. "Alright boy, face me and get on your knees."

It was here that Caleb appreciated how much work Kassam had put into his play space: when Caleb assumed the correct position between Kassam's legs, his knees were padded somewhat by the material on the floor--the canine realized that, in all likelihood, he'd probably be spending hours on his knees and back on the floor, and Kassam had put in the effort to reduce soreness in his subs.

The tiger smiled lewdly down at the lab, then raised his left foot and rested it on his prey's shoulder. Caleb stayed still, taking the weight of Kassam's heavy leg as his calf pressed against his still damp ear and the side of his sweaty face. Kassam then raised his right foot and held it directly in front of Caleb's muzzle, toes splayed and sole only a few inches before the lab's mouth. He wiggled his toes so he jostled Caleb's nose ring and chuckled at the dog's small recoil at the sensation.

"Go on, pup, show me what you can do," Kassam said.

Caleb immediately leaned forward and planted his nose between Kassam's toes and breathed in. The musk was intoxicating, just the right mix of sweat and body odor without being too intense for his nose. His cock strained further against his cage as he basked in the knowledge that with the scent he inhaled and action he performed, he was cementing his place as a tool to be used purely for the tiger's pleasure--here he was, literally at Kassam's big, powerful feet, burying his nose in the paw pads, doing exactly what a dog like he was meant to do. It was a gift for him to be allowed to perform this service for his master. He unfurled his long tongue from his mouth and slowly, savoringly, licked up the sole of Kassam's foot--he felt the toes wiggle appreciatively in his face before he slurped them, too. As delicious as it smelled, the tiger's foot tasted even more heavenly. So entranced was Caleb in what he was doing that he almost missed out on hearing the contented rumbling from Kassam.

The tiger watched intently as the young lab, still soaked in sweat from his run, his eyes lazily closed in pleasure, lapped at his foot--the wide dog tongue rubbed wetly across the sensitive spots perfectly, getting every inch of the sole and wrapping around the toes before Caleb nibbled, kissed, and sucked them, then repeated the process for as long as the tiger let him. Kassam arched his foot, trying to increase the surface area for Caleb to drool over, and noted to himself that Leon had trained his kid well. The tiger mentally conceded that it was almost a pity what was going to happen during their session, as the young lab had real talent. But just because Kassam had plans for both father and son didn't mean that he couldn't take his time to enjoy himself.

"Alright, pup, even it out and get my other foot," Kassam said, removing his right foot from Caleb's muzzle and replacing it with his left. Caleb greedily attended the new foot in front of him while Kassam settled his right foot between Caleb's bent legs--specifically on the canine's caged cock. Kassam rested his foot there lightly for a few minutes as Caleb treated his left foot to the same tongue bath treatment, then began to bounce his paw up and down on the boy's crotch. He grinned as he felt Caleb subtly hump upwards against his foot, then he pressed down and elicited a moan from Caleb as the young lab felt the pressure against his sore, restrained penis and balls. "You like my foot there, boy?"

"Yes, Daddy," Caleb groaned between licks.

"Mmm, you want Daddy to let you out of that cage?"

Caleb licked a few more times before saying, "Only if you think I've earned it, Sir."

Kassam laughed. "Good answer, kid. How do you think you can earn it? Just by being my foot slave?"

"I need to do more, Daddy," Caleb responded. "I need to serve you, work hard for you, to do anything and everything you tell me to."

"Look at that, my pup's a natural little sub, isn't he?" Kassam nodded cockily. He pulled his foot away from Caleb and planted both feet on either side of the canine, spreading his legs before the eager and panting boy. He then brought his arms back so his head rested in his hands, the picture of relaxation. "Well, go on, get Daddy's shorts off and get to work on what you find in there."

Caleb shuffled forward on his knees so he settled with his head in Kassam's lap. He leaned further and, after rooting around for a moment below Kassam's navel, grabbed the tiger's waistband in his teeth. He pulled back, dragging the shorts clumsily down Kassam's hips and revealing a semi-hard, barbed, thick cock and pair of plump, furred balls, all bundled together with a thick metal cockring. The tiger raised his hips slightly so Caleb could continue pulling the shorts down his thighs, then over his knees, where gravity took over and the shorts fell to the floor around Kassam's feet. Still keeping his hands tucked behind his head, Kassam kicked the shorts away and shifted in his seat to get more comfortable. As he did so, Caleb inspected his genitals for a moment: Kassam was no stranger to body modification below the waist, as he had not only a subincision a quarter of the way down his growing cock--exposing and widening part of his urethra--but also a scrotal ladder with three gold hafada piercings. Caleb watched as the tiger's penis engorged with blood, taking a few moments to stand tall and proud as Kassam purred above.

Caleb immediately sank the cock into his mouth, reveling in the sensation of the barbs and subincision against his tongue and palate. He bobbed his head back and forth for a minute, pushing to get Kassam all the way into his throat, before slowing down and lightly raking his teeth across the sensitive flesh--Kassam's purring grew louder. Caleb then focused on nursing on the head, flicking his tongue in and out of the subincision. Above, he heard Kassam groan.

"Oh, your dad did the exact same thing. Think you can get your tongue down my cock like he did?"

Rising to the challenge, Caleb began to push with his tongue at Kassam's subincision, tasting traces of sweet pre as he did so. Slowly, gently, he fed his squishy tongue into the urethral opening, enjoying the tightness and taste; drool flowed freely from his mouth onto Kassam's crotch, soaking into the tiger's fur. He wriggled his tongue back and forth within Kassam's cock, and he was rewarded by the tiger starting to thrust lightly upward into his mouth. Caleb managed to get three inches down before his tongue started to feel sore from the workout--before he pulled out, though, he slid his head down along the length of Kassam's member, all the way until his lips met the top of the cock ring and he felt the first hafada piercing under his chin. His tongue ached from the twisted position of being stuck in Kassam's cock and going down his own throat, and he could only hold the position for a moment before releasing Kassam's thick flesh from his mouth. With a "schlorp", he yanked out his tongue as fast as he could, stimulating Kassam's urethra.

"Oh, that's good, boy, very good," Kassam moaned with a soft smile. He looked down at Caleb, who licked his lips, savoring the taste of the tiger's cock, musk, and pre. Kassam leaned down and rubbed the dog's head and cheeks. "Such a good pup who takes his master's cock. Ready to see your dad?"

"Yes, Sir!" Caleb's tail thumped against the floor.

"Alright, stay on your knees and turn around."

Caleb shuffled so he faced the same direction as Kassam. Meanwhile, the tiger picked his phone up from the table and stood from his chair. Kassam stepped over Caleb--the bottom of his balls and tail brushing against the top of the canine's head--and walked to the cluster of cylinders. He turned to face the canine on his knees and tapped a command on his phone.

The cluster smoothly rotated in its housing like a carousel, stopping after three cylinders had passed Kassam. Then, with another tapped command on Kassam's phone, latches at the bottom of the cylinder at the front unclasped from the housing, and the metal sheeting folded up into the ceiling, revealing another clear cylinder underneath made out of shatterproof glass. And there, on his knees on a platform in the middle of the cylinder, was Leon.

Caleb gasped when he saw his father--the older, nude dog was panting heavily and wore a set of headphones, though his eyes were closed. Leon's hands were free and he placed them on his knees, while between his legs, Caleb saw that his cock (now free from chastity) was fully erect, throbbing, and dripping pre; his bulbous knot looked even bigger than it normally did. At the sight of his father in this position, Caleb's cock pressed even harder against his cage.

"There's your old man. Let me tell you, he's able to take a lot of punishment for a man his age," Kassam grinned. "He's got something to show you, too."

Kassam tapped on his phone again, and the platform inside the cylinder rotated 180 degrees, turning Leon around so his backside showed to Caleb. The tiger then held a button down on his phone and said aloud, "Present for me."

Caleb watched as Leon leaned forward onto his hands and widened his stance. The older lab then reached back, raised his tail, and spread his ass cheeks apart to show off his abused hole, his lips puffy and clearly gaping, almost actively bulging outwards. The fur on his taint, cheeks, and upper inner thighs was matted in lube, and between his legs, Caleb could see his dad's pendulous balls hanging.

"Show off," Kassam commanded as he held down the microphone button on his phone's app again.

Leon's hole winked a few times, and then Caleb saw the lab's gape widen and expand until a circle of bright, deep red appeared beneath his tail--Caleb, staring in fascination, realized he was seeing into his father's rectum. But the show wasn't over yet: the muscles contracted a fraction before pushing out, blooming into a wrinkled, pulsing rosebud that extended a few inches from Leon's anus and glistened wetly in the light shining from the top of the cylinder--Leon's shoulders rose and settled placidly, as if he were exhaling his rosebud out like a cleansing breath. Caleb's eyebrows rose and he ogled his father's ruined hole, trying to wrap his head around at how much work it must have taken for Kassam to get Leon to prolapse to such a degree after just two hours of playtime. Clear strings of lube dripped from the rosebud; Leon pushed further before relaxing again, then pushed and relaxed, as if inviting his son to come dine on him. In the back of his mind, Caleb desperately hoped that Kassam would let him suckle, slurp, and chew on the engorged and pulsing flesh, driving his father into higher ecstasy. He couldn't help but salivate and lick his chops.

"You like seeing your dad's wrecked hole, pup?" Kassam asked, watching Caleb's reaction with satisfaction. "That's all my handiwork."

"Yes, Sir! How did you get him that opened up?"

"I have my little ways. Although he was begging like a little bitch for more just before you arrived," Kassam replied, padding back toward Caleb, his still-erect tiger cock bouncing with each step. He scrolled through the media library in his app and, by the time he kneeled down next to Caleb, he had pulled up the video he wanted to watch. He held the phone up to the younger man's eyes and tapped the triangle icon to play the video.

Caleb watched, transfixed by the scene that played on the screen in front of him: Leon was strapped down to the metal worktable, his legs tucked under him in a way that spread his cheeks wide apart and his arms strapped separately to the far end of the table. His tail was also caught in a strap and hooked up to the ceiling, keeping it out of the way--captured in the camera angle was an orange and white arm with black stripes, fur slicked with lube, that pounded into Leon, fist curled tight and the flattest part of it sinking in first to spread the older dog's hole as much as possible.

The audio for the video played on the hidden speakers in the room, surrounding Kassam and Caleb with the sounds of Leon's grunts and moans and the wet slapping and schlorping of flesh sliding in and out of flesh. Leon jostled rhythmically to the force that pushed him back and forth on the table; another camera angle revealed Kassam, naked as he was now and punching in and out of Leon's already battered hole, his lips being dragged out and forced in by the movement of the tiger's meaty arm fucking him--each time the fist emerged, Kassam would plunge it back in quickly, refusing to give Leon a break. Not that it sounded like he wanted one.

"Ooooh...fuck me please...Sir, it's....sooooooo good," Caleb heard his dad groan from the speakers around him.

"Yeah. Good. Dog. Let's. Get. That. Tail. Hole. Opened. Up," Kassam growled, emphasizing each word with a punch into Leon's rectum.

The camera angle switched again, this time showing Leon's face as his head rested on the table: his eyes had rolled to the top of his head, his tongue hung out of his mouth and was uncontrollably lolling on the cool work surface. Drool dripped from his mouth in ropes down his tongue and onto the metal, pooling around and below his chin.

"Open. Up. More. For. Me. You. Tight. Bitch," Kassam continued in the background.

The camera moved smoothly to show Leon's hanging belly moving in time with Kassam's fisting, then continued around to the lab's cock: in the video, it was still locked up tight, but David could tell it was filling out his father's sheath enough that the knot had already inflated--Leon must have been crazy horned up at that point, as his pre was freely flowing like piss and splattering on the table at a steady rate.

"Ooooooooh Daddy..." Leon moaned loudly. "P-please...more..."

The camera angle shifted once more, now focusing on Kassam, who had sped up his punching and was keeping his depth a little more shallow; when he had at first been sinking half of his forearm into Leon's ass, the tiger now stopped just after his wrist. With an excited lurch in his stomach, Caleb realized Kassam was violently milking his dad's prostate, punching the organ into submission and forcing it to produce more and more pre for Leon's dick to dribble out.

As Caleb continued to watch his father get completely wrecked by Kassam's vigorous fisting, he didn't notice the pattern of shapes and colors that was starting to play on a layer on top of the video, he was too enthralled by the scene playing behind them. However, another audience member had seen them, and had, in fact, planted them there.

Kassam grinned as he watched the faint circles expand and swirl together as they contracted, then repeated in incrementally faster intervals, and he knew that the sub-audible frequency was going to start playing from the speakers he'd embedded in the walls--eventually it would completely replace the audio from the video, but it would happen so slowly and imperceptibly that by the time Caleb would sense something amiss, it would be far too late.

It had taken Kassam quite some time to perfect this next step of his plan, the technology and acoustic engineering had to work flawlessly, especially for the small buds he had developed and currently hidden in his ears to filter out the frequency that would help him dominate yet another unsuspecting mind. The visual hypnosis was something he could train himself to resist, as it was much weaker on its own--it was the aural hypnotic frequencies, in combination with the visuals, that sealed fates and commanded thralls. He'd already used it on the father, now it was time to complete the set and have some real fun.

With a satisfied smirk, he continued holding the phone up to Caleb's eyes. While Caleb subconsciously looked where the circles commanded him to--his gaze alternating between the scene of his father getting fisted and the swirling that gently commanded more and more of his attention--Kassam intentionally looked at the "safe zone", a visual failsafe he had built into the video so he could focus on the show without the risk of watching the hypnotic display: in this case, the zone was the lower left corner of the screen, where Leon's cock still drooled copious amounts of pre and his balls swung back and forth. The tiger licked his lips, as there really was something so rewarding about seeing the results of his own prostate milking efforts. Just three other victims had been used specifically to practice that particular skill.

Meanwhile, the sub-audible frequency grew in volume, and Kassam noticed Caleb's ears start to perk slightly, but the boy paid them no mind; even if his body was recognizing signs of danger and subversion, he consciously wouldn't be able to do anything. 10 minutes passed, and the video was significantly faded, with the expanding and contracting circles and swirls much more visible. Kassam glanced at Caleb's eyes and noticed faint, lazy rings of color pulsing from his irises. The canine hadn't blinked for a while now, his mouth hung open, and he was much more hunched over and relaxed as he stared at the phone. The pulsing, whispering, dominating frequency on the speakers was clearly audible over the sound of the video now, with Leon's moans of pleasure waning in the background.

Kassam couldn't help himself: it would happen so soon now, and with Caleb's last few moments of freedom, he wanted the younger canine to know what he was in for, what was in store for his new life. He could time it perfectly.

"You keep watching your old man get filled up by a true predator," Kassam said softly to Caleb. As he held the phone screen steadily in his hand, he leaned in and licked the lab's neck again, but Caleb paid him no mind. The remnants of sweat and musk still lingered as a delicious snack for Kassam. Between the laps of his tongue, he continued, "You watch as I open his hole wider than you'd think possible. And then imagine yourself in that situation. But here's the thing--you won't have to imagine it for much longer. Because I'm going to do that to you, too, boy. I'm going to do that and so much more, to both you and your dad."

Unbidden, Caleb arched his back and slumped again--it was the telltale "ping" that had happened in his brain, the moment when the hypnosis fully took over. There was just one more thing for Kassam to wait for...any second now...

"Yes, Daddy. Anything and...everything you want," Caleb moaned softly.

There it was: the phrase Kassam's hypnosis commanded his prey to say when they were completely under his control. The tiger closed the video on his phone screen and tapped a button to turn off the aural hypnosis frequency--Caleb remained rooted to the spot as the colored rings in his eyes slowly expanded outward and swirled. Kassam knew from long experimental trials that the boy's mind was empty, vacant of higher executive function, just like his father.

Now the true fun could start. Safe words like "watermelon" would never be said in this room.

Kassam stood from his kneeling position next to Caleb and deposited his phone on the table next to his easy chair. He walked past the cluster of cylinders--Leon still in his container, bent over with his prolapse pushed out--over to the steel worktable, where he pulled open one of the drawers and withdrew Leon's keychain and a pair of scissors. The tiger then strode back to Caleb and set the scissors and keychain down on the table, exchanging them for his phone. On the app he had developed to connect to all the tools and equipment in his playroom, he navigated to the commands for the cylinders. For Leon's, he rotated the older lab's platform back so father could face son; Kassam double-tapped the microphone button on his app, locking it in the "hot" state so he wouldn't have to hold it to speak to Leon or give him commands over the dog's headphones--the shatterproof glass of the cylinders was specially formulated to be soundproof, so the headphones that the canine wore to be controlled were as essential as the earbuds the feline wore for for keeping control.

"Rosebud in, on your knees."

With another exhale and a smile, Leon relaxed the muscles keeping his prolapse out, allowing it to collapse back inside his ass, and then resettled on his knees with his hands resting on his thighs.

"Open your eyes, stay still, no speaking, wake mode," said Kassam.

Leon's eyelids fluttered open, showing the swirling rings in his eyes, too. As he took in the sight before him--his son on his knees just 10 feet away, his eyes and vacant expression clearly showing the signs of hypnotism, and Kassam domineeringly standing next to him--Leon's emotions and thoughts surged from confusion to surprise to intrigue. But the tiger's commands prevented him from saying anything, from even moving except to breathe, pump blood through his body, blink, and shift his gaze.

In his tinkering, Kassam had discovered that "wake mode" was enough for his victim to be completely conscious of what was happening around and to them--their senses were fully available and their minds totally active, but they wouldn't be released from his control unless he gave the order. Kassam had only ever given that order in experiments before, but he had no inclination to give it, not until the opportune moment. In essence, Leon's mind was locked in a body that no longer obeyed or belonged to him--both he and his son belonged to the tiger now, Leon and Caleb's minds were just along for the ride.

Kassam carried the phone with him as he lazily stalked toward the cylinders, addressing Leon as he approached. "I really should thank you both for presenting yourselves to me. Such easy targets. Especially with a hole as widened and loose as yours is now--anyone who sees it would instantly know what an insatiably horny, slutty father you are," he finished, coming to a stop directly in front of Leon. He smirked down at the dog, who was forced to stare at the tiger's impressive cock that had bobbed with each step. "If anyone else did see your hole, that is," Kassam added after a pause. He squatted on his haunches so he was eye-to-eye with Leon. "You're all mine now, though. And what I did to you, I'm going to make you do to your boy back there. Want to watch the show?"

Leon didn't move a muscle.

"Go ahead and nod for me."

The canine slowly nodded, his eyes never leaving Kassam's.

"Good dog. Let's get started."

Kassam turned away from Leon's containment cylinder and strode back over to Caleb, who was still in "sleep mode", blissfully unaware of what was happening. Kassam decided to let him stay that way for a while longer, it would do the boy some good to give his brain a rest before all the action took off. In the meantime, the tiger placed his phone back on the table next to his chair and took up the pair of scissors, then moved to stand behind Caleb.

Slowly, he snipped the left arm strap of Caleb's running tank, cutting through the fabric with ease. The strips of cloth dangled from the canine's shoulder, and Kassam delicately cut down along the left side of the shirt, from Caleb's armpit to his waist. He repeated this on the right side, first cutting the shoulder strap, then the rest of the shirt, and let the pieces of fabric fall away, revealing the younger lab's athletically toned frame--Kassam circled him, taking his time to survey and appreciate the musculature of Caleb's back, stomach, chest, and shoulders. He certainly wasn't as built as the tiger, but it was clear he spent time on the track and in the gym. If his life had continued without encountering Kassam, he would have no doubt turned into his father in another 30 years. Kassam completed his orbit, stopping behind Caleb once more.

"Stand for me, pup."

Caleb rocked back on his feet to keep his balance while still wearing the handcuffs. As he rose, his back rubbed against Kassam's erection, teasing the tiger with the short fur.

Leon, statue-still and enraptured by the scene in front of him, watched as Kassam reached over Caleb's shoulders and, with his free hand, grabbed the waistband of his running shorts. The back blade of the scissors dipped between Caleb's groin and the fabric gathered in the tiger's hand--the shears snapped shut, cutting the waistband. Kassam continued to cut down the seam of Caleb's shorts, and let go of the band he still held; the shorts fell to the ground, allowing him to exhibit his caged cock and balls to his father. Leon couldn't help but consider the dirty and lewd acts he would commit if he and Kassam switched places.

Kassam instructed Caleb to step out of the shorts so he would be unencumbered by the now-useless scraps, then walked around him to stand next to Leon's cylinder; he stopped and looked at the boy on display, as if contemplating a sculpture in a museum; Caleb breathed languidly with his eyelids lazily drooping, like he was ready to doze off any second. Kassam shook his head to himself, grateful for just what a catch he had managed to snag with both labs.

"I'll let you look at him for a little longer," Kassam said to Leon. He turned back to his metal workstation and returned the scissors to their proper place in one of the drawers, then made his way back to the table next to his easy chair, where Leon's keychain still rested. He picked it up and selected the small key with a blue label on it--there was another with a red label he had already used to open Leon's cage, now it was time to use the blue key for Caleb's.

Kassam unceremoniously seized Caleb's chastity cage and twisted the key in the lock, unlatching the metal clasp that had kept it tightly shut. He roughly tugged off the ring at the base of Caleb's sheath and balls--had the canine been fully conscious, he would have been wincing and panting at the squeezes and pinches to his plump and aching nuts, but right now any sensation brought him nothing but subconscious pleasure. And he was still so aroused that as Kassam removed the cage, his cock rushed upward, stopping only just as the knot had begun to emerge--it was too inflated to move any further by itself past the tight sheath opening, and the bulbous shape was visible within Caleb's sheath.

"Looks like you need some help there," Kassam said, noticing the young lab's predicament. With his free hand, he spread his fingers around Caleb's cock, pressing down on the fur and flesh of his sheath until...

Pop.

Caleb's swollen knot sprang out, tightly trapping Kassam's fingers between the base of the canine's penis and sheath. The tiger grinned and rooted around within for a moment, grabbing the root of Caleb's cock and squeezing it to stimulate it more.

"That's a big, thick boy, you take after your old man, don't you," Kassam said, removing his hand and taking the cage back to his worktable--he opened another drawer and deposited Caleb's cage and the keychain inside next to Leon's and seven other cages. From another drawer, he pulled out three syringes and a labeled ampoule: it was a cocktail of hormones, endorphins, and steroids he had synthesized himself and had tested extensively to exponentially increase semen production, heighten libido, enhance stamina, and induce a slight sense of euphoria in his subjects, with the beneficial side effect that it caused swelling in male genitalia. A few shots of his proprietary blend and Caleb's balls would be churning in no time--he had already injected Leon, and he had no doubt that the older dog's testicles were ready to burst; the large puddle of pre from the fisting session still on his worktable was ample evidence of that.

Kassam hummed to himself as he loaded all three syringes with the synthesized chemicals, then he replaced the ampoule in the drawer and carried the needles over to his easy chair, where he sat.

"Come here, boy, stand in front of me, keep facing your father," he commanded Caleb.

Leon could only watch on as his son stood between Kassam's spread legs and waited dutifully for his injections. A pang of fear and paternal protectiveness bolted through the older lab; he didn't want Caleb to feel any pain for his shots, but on some deep level--a level he was surprised to find that he had somehow acquired, perhaps through the hypnosis and mental conditioning that had happened to him--he conceded that this was necessary, that the tiger was doing this to help his son. In fact, to help both of them. Yes, maybe Kassam was doing what was best for them, and they should let him continue.

The tiger took the first syringe in his right hand and cupped Caleb's balls with his left. He rolled them in his palm until he had a testicle firmly in his grip, then pushed the needle through the back of the canine's scrotum and sank it into the organ tissue within. Caleb didn't flinch or move a muscle during the procedure. Kassam squeezed down on the plunger, delivering the first dose.

"There we go, one down," Kassam murmured reassuringly. He absentmindedly massaged the testicle, promoting circulation to get the payload into Caleb's system, as he laid down the first syringe and picked up the second one. He repeated the process with Caleb's other testicle: he rolled it in his palm until it was secure in his grasp, pierced the scrotum and organ with the needle, and injected the blend before pulling out the empty syringe and massaging the testicle.

"Two down, one to go."

Before Kassam gave Caleb his third dose, he pulled open the drawer of the table next to his chair and retrieved a small key, which he used to unlock the handcuffs still binding the younger lab's wrists. He removed the cuffs and put them in the drawer while Caleb's hands fell limply to his sides.

"Bend over and touch your feet for me, kid."

Caleb did as he was told, his fingers resting on top of his toes as he waited--his taint and hole were exposed to Kassam's exploring fingers. The tiger felt the perineum, probing with his fingers for the perfect spot, which he found after a moment; with a chuckle, he realized that it was the exact same spot as Leon's, just about an inch and a half behind the scrotum.

"Oh, like father, like son," Kassam mused. He looked up, past Caleb's back and at Leon. "If he has the exact same rosebud pattern as you, I might just have to keep you both as-is instead of putting you in my little project."

Still wearing a smile on his face, Kassam took the third syringe in hand and sank the needle into the spot he'd found; as soon as he felt it connect with the firmer tissue of Caleb's prostate, he injected the third dose and pulled out again, massaging the site as he discarded the syringe. "Last one, pup. You did so good, Daddy's very proud of you."

He smacked Caleb's ass and said, "Alright, get up and go over to the fuck bench. Wait there."

As Caleb stood and slowly walked to one of the fuck benches in the corner, Kassam tapped a command button on his phone.

With a hiss, the cylinder containing Leon released from hidden seals in its housing in the ceiling and sank into the floor, eventually disappearing entirely. Leon still sat facing Kassam--the tiger stood and strode over to the older lab and tugged off the headphones.

"Go to the fuck bench that Caleb is standing next to and get on it."

Kassam watched as Leon stood from the platform, stepped off of it and out of the cluster of cylinders, and began to carry out his orders. But just as Leon approached the fuck bench, Kassam called out, "Wait. Make out with your son."

Leon turned to Caleb and took the young man's face in his hands, bringing them closer together to meet for a deep kiss, Leon's tongue tenderly slipping into Caleb's mouth. Caleb returned the kiss with equal passion, wrapping his arms around his father's shoulders, and their engorged cocks rubbed and throbbed together as beads of pre began to form at their respective tips.

"Alright, that's enough, you two. Get on the bench, Leon," Kassam said, putting an end to the display.

Leon pulled back, breaking the kiss with Caleb, and did as he was told; he laid down on his stomach on the bench, placing his legs and arms on the appropriate leather cushions and laying his head down on the rest.

"Buckle him in, Caleb," Kassam instructed.

The younger lab buckled and cinched the restraints around Leon's ankles, knees, hips, biceps, wrists, waist, and shoulders. While they technically weren't necessary due to Kassam's hypnosis, the tiger still enjoyed seeing the straps in use, especially when he gave his next command.

"Leon, you can struggle as much as you want while your son fucks you. Make some good moaning, too. Caleb, wake mode. You're going to fuck your dad as hard as possible--make it merciless, open him up wide with your knot. And give us some good dirty talk. Go."

Right on cue, Caleb positioned himself behind his father, between his strapped legs, and shoved his dry cock into Leon's well-lubed and gaping hole. Leon gasped and shuddered, then moaned in pleasure.

"Fuuuuuck, Dad, your hole is so loose and warm, Daddy fisted you so good," Caleb said as he humped with abandon, his hips slapping against Leon's glutes--the lube still on Leon connected with Caleb's thighs, forming slimy strings between them. The puffy lips around the rim of Leon's ass ached and contracted around his son's hard cock plunging inside, but his rectal walls had begun to move more and more--with each thrust, the friction of Caleb's cock (even though it was now slick with the liberal amounts of lube still deep within Leon) drew out Leon's rosebud.

Leon couldn't help it, he just had to push out and help his son enjoy the damage that Kassam had wreaked on his hole. His rosebud blossomed around Caleb's cock to the point that the younger lab was penetrating it two inches outside of Leon's hole before fully entering the older man's ass. Caleb, following Kassam's instructions, easily popped his knot in and out of his father's abused hole, reveling in the sensations--he had fucked Leon before, but the engorged prolapse that now engulfed his cock was something completely new, there were folds he had never felt until now that rippled around his sensitive flesh with wet squelching as he slammed hard into Leon. For better leverage and to steady himself more, Caleb raised his right foot onto the cushion that Leon's right leg was strapped onto, properly mounting his father and hilting himself within the sleeve of red flesh that welcomed him warmly.

Kassam lazily stroked his cock, gently fingering his subincision as he watched the two labs go at it. He wanted to stay out of the way for a while as the hidden microcameras he had placed in the room captured multiple angles of the scene--this was definitely something he'd want to replay on his big screen when he was done. For 15 minutes, he listened to the "plap, plap, plap" of balls and hips slapping into each other and Caleb as he continued talking over Leon's lewd moaning.

"Yeah, you take my cock like a bitch in heat...Fuck, you're so slick back here, Daddy did a number on you...Look at you, begging for your son to keep breeding you...if Daddy lets me, I'll load you up with a litter or two...Shit, yeah, that's a good spot right there...Let's see if I can hit your prostate as good as Daddy did when he was fisting you...You like that, don't you, Dad..." Eventually, Kassam stood from his easy chair and sauntered over to the bench; he circled around to Leon's head.

"Open your mouth, big dog," Kassam commanded.

Leon complied without hesitation, opening his jaws wide and rolling out the pink carpet that was his tongue--he let it hang out for Kassam, who first lightly slapped his hard cock against the sides of Leon's face, then rested his barbed penis on the dog's tongue. He pushed his cock along it slowly, methodically, before dragging back, feeling the wet muscle curl involuntarily around his sensitive head.

Kassam pushed his cock back in until he felt it press against the back of Leon's throat, then reached down and used his hands to close Leon's mouth around his cock, stopping when he felt the barest graze of the canine's teeth.

"Start sucking."

Leon sucked and nursed and bobbed his head back and forth, lapping and swirling his tongue up and down on Kassam's thick meat. Kassam rumbled appreciatively, slowly thrusting his hips. He kept it up for another few minutes before dominantly planting a hand on Leon's snout.

"Get your tongue in my cock and fuck me with it," he growled down at the older dog.

Leon complied, first teasing the tip of Kassam's cock with his tongue, then lapping at the subincision, which oozed pre. Leon swallowed and continued his work, slipping his tongue further into Kassam's widened urethra, wriggling past where Caleb had gotten--Leon managed to get halfway down the tiger's shaft. He concentrated, pulling his tongue back and pushing it forward, again, and again, again, sliding the salivating muscle through the tight passage to stimulate Kassam from the inside out.

Kassam, satisfied with Leon's service, looked to the lab's rear, enjoying the show just a few feet away from him. Caleb was baring his teeth and growling huskily, reaming his father as hard as he could. Kassam watched for another few minutes, taking in the sight before it was time to continue. Based on the amount of physical activity and time since injecting Caleb's testicles and prostate with his chemical blend, the tiger guessed that the boy's balls were boiling and overflowing with cum. Time to empty them, at least momentarily.

"Go ahead, Caleb. Breed your dad's ass and eat it out."

At the sound of the command, Caleb humped even faster, wrecking Leon's hole with his knot before hilting himself inside one last time and howling loudly; Leon's clenched his rosebud back within himself with Caleb's cock inside, drawing his son further in as the younger lab's muscles contracted; Caleb pushed his hips back and forth against Leon's rump, pumping the contents of his balls as far into his father as he could. He pumped for a full minute, letting the cum flow in thick streams that coated Leon's guts. Caleb then braced himself against Leon's back for a moment, and then roughly pulled his knot free from the battered, dripping hole. Caleb fingered it tenderly before Leon pushed out again, letting his rosebud--now frosted with white, dripping, cum in its folds--emerge once more. The younger lab immediately sank to his knees and pushed his nose into his father's prolapse, sniffing deeply before he opened his mouth. Caleb breathed heavily on the exposed flesh, teasing and tickling it with his tongue, and then closed his mouth and slurped hard on it, sucking away the mix of cum, pre, and lube that had filled his father's hole. The hot, musky, cum-drenched muscle filled Caleb's mouth, and as he licked and sucked, he also lightly chewed on the tender flesh, the combination of teeth and pressure eliciting muffled moans from his father around Kassam's penis.

Kassam looked on as Caleb ate out Leon's ass, feltching his load loudly and coating his chin in his own sperm as he messily chowed down. Eventually, Kassam said, "Good job. Now, go to the toy cabinet and pull out that dildo on the fifth shelf down. Get some lube, and start fucking yourself on it."

With one last slurp, Caleb stopped eating out Leon and did as he was told. In his mind, he was still conscious and floating in a haze of lust, watching as his body performed the actions it had been commanded to. He pulled out the dildo Kassam had noted for him: a fist and arm-shaped rod of silicone thicker than a beer can. Caleb coated it in slippery lube and positioned it on the floor so Kassam could watch, then began to lower himself onto it. The fist popped into his hole first, then the wrist and first section of the forearm, before Caleb stopped; he squatted up and down to loosen up more, fucking himself on the black silicone.

In the meantime, Kassam pulled his cock from Leon's mouth and began unbuckling him from the fuck bench--as he undid the straps around his waist, Kassam saw another puddle of pre had formed around Leon's cock. The tiger, amused, shook his head to himself and swiped a finger through the pre; he brought it to his tongue, tasting it.

"Mm, I could bottle this up and make a fortune," he told Leon as he rubbed his thumb over the sensitive tip of his cock, causing more pre to leak out. "Now, go over to Caleb and..." He whispered his command into the canine's ear. Leon pushed himself up off of the fuck bench and ambled over to his son, who continued to bear down on the dildo. Kassam followed behind him, and Caleb looked up at his father as Leon approached; the older lab gently took the sides of Caleb's head in his hands and pulled him down onto his dripping cock while Kassam took his position nearby to watch. Caleb acquiesced immediately as he kept up his rhythm of riding the dildo. He sank his lips down, down to his father's knot, then over the hot bulb of flesh, blood, and nerves, and to the root of his cock, his nose bumping into Leon's stomach; his throat bulged as Leon's cock pushed down into his esophagus.

"Go ahead, Dad, turn on the tap," Kassam said.

With his cock fully knotted in Caleb's maw, Leon relaxed and let a thick stream of urine flow from his bladder and down his son's throat. Caleb reflexively gulped, his Adam's apple bobbing against the tip of Leon's cock, while the warm piss drained into his stomach.

Caleb continued guzzling down his father's urine as another stream of liquid hit his side--Kassam had taken aim and guided his piss to coat the younger lab's stomach, chest, and face. Clear, fragrant piss dribbled down Caleb's head, over his eyes, and down his snout--it formed into rivulets that trickled down his groin, between his legs, and splattered on the dildo Caleb still worked into himself. Kassam steadily circled the duo, pissing first on Caleb, then hosing down Leon's wide belly and legs; he also made sure to piss more on Caleb's snout, the stream hitting the canine's cheeks that housed his father's still-urinating cock within.

Eventually Leon's bladder fully emptied, with every last drop safely contained in Caleb's belly. Kassam had also finished, thoroughly soaking both canines with his urine and leaving them standing and squatting in a puddle of it.

"Take your cock out of Caleb's mouth and get on all fours," Kassam said to Leon.

The older dog carried out the order, removing his knotted cock from his son's mouth with a wet plop--thick strings of drool briefly connected Leon's member and Caleb's tongue before he got on his hands and knees in the puddle of urine. In his new position, he was eye-level with his son, who continued to fuck himself on the silicone fist and arm. By this point, Caleb had managed to take two more inches of the toy into himself, leaving just another six inches to work on.

Kassam knelt down behind Leon.

"Raise your tail for me, dog."

Leon did so, fully exposing his completely ruined hole that was still wet with lube and the vestiges of Caleb's semen and saliva. Kassam prodded at it with four fingers, sinking them in with ease--his thumb joined in for a full fist. He rotated his wrist and relished the sensation of the stretchy, wet muscle rubbing past his fingers. The tiger then reached further in and pressed down against the raised lump he was looking for; as he did so, a viscous stream of pre dripped from Leon's cock and connected with the piss on the floor. Kassam grinned and, with his free hand, reached between Leon's legs and began pumping the dog's stiff cock, first tugging down on the base of his knot, then stroking over the shaft. At the same time, he kneaded Leon's prostate at a regular tempo, synchronizing with the rhythm Caleb set as he rode the dildo. Kassam kept up with Caleb, milking Leon and drawing out more pre to drip to the floor. By the time Caleb had visibly taken another three inches of his toy into his ass, Kassam decided it was time to move forward. He pulled his hand out of Leon's ass and held it under the drooling cock he stroked, catching pre in his wet palm.

"Hump my hand and cum for me, Dad."

Leon rapidly bucked his hips, rubbing his cock in Kassam's tight grip, before the familiar muscle contractions fired, and thick white ropes of cum forcefully shot into the tiger's open palm held just below the tip of the dog's cock.

"Good dog, very good," Kassam crooned, watching as the thick, hot liquid splattered into his hand, seeping into the nooks and crannies between his fingers and paw pads. Leon continued humping, his body acting on the tiger's orders--cum kept splashing into the puddle that had accumulated in Kassam's palm, and the excess dripped to the floor, mixing with the piss that still remained. Eventually, Leon's orgasm subsided, the semen slowing to a slow ooze before stopping.

"Alright, hold still," Kassam told Leon, who obeyed.

Kassam stood and positioned himself behind Caleb, who had been pushing himself further and further down on the dildo the whole time he watched his father get milked--there was only one inch to go before he hit the floor. Kassam held his free hand on Caleb's shoulder and thrust his cum-filled palm up to the younger lab's face. "Eat it up, boy."

Caleb jumped to it, eagerly licking his father's seed from Kassam's palm; the tiger tipped his hand to better angle the still-warm cum into Caleb's mouth, and he groaned softly at the feeling of the dog's tongue lapping up the white liquid from his hand. As Caleb messily slurped and swallowed, smearing and slopping cum on his lips and chin, Kassam pushed down on the canine's shoulder, forcing him down further until the dildo was finally inserted completely inside him and his spread ass cheeks touched the floor.

"Mm, gonna move you on to the real deal soon," Kassam murmured. "Although before that, let's have a little more fun. Leon, go to the toy cabinet and pull out the box on the bottom shelf, and put it on my worktable."

As Leon carried out Kassam's orders, the tiger instructed Caleb to rise, still holding the dildo fully-engulfed in his rectum; together they walked over to the work table, where Kassam helped Caleb up onto the metal surface, keeping a firm hand on the base of the dildo to keep it in place for the canine. Kassam released his grip when he was sure that Caleb could keep the toy in by himself. Then, at the feline's bidding, Leon clambered onto the table, too, and Kassam positioned father and son to face each other--they sat lap-to-lap, with Caleb's thighs resting on Leon's, his cock throbbing against his father's while the dildo still within his rectum continued to stretch him.

Kassam reached into the box that Leon had placed on the table and pulled out a 30-inch long, 12-millimeter thick silicone tube. After examining the tube to ensure it was still intact and ready to use, Kassam dribbled lube in his palm and rolled the tube in it so the entire thing was coated in a layer of the viscous fluid.

"Hold up your cock for me," he commanded Caleb.

The younger lab gripped his still-erect, knotted cock and aimed it upward for Kassam; carefully, the tiger began to feed the thick tubing into Caleb's urethra, stretching it wider than it had ever been before. Trapped in his mind, Caleb could feel the sensation of the tube pushing down into him, further into his shaft, through his knot, and down into his perineum. There was some resistance when the tube started to connect with his prostate, which was already squeezed from behind by the thick toy lodged in Caleb's ass.

Kassam commanded him to relax; as Caleb's body obeyed, the pressure melted and seeped away as the tube pressed into his prostate and rubbed sensually against the organ on its route to his bladder. The remaining length of tube that led from Caleb's cock and to Kassam's hand began to fill with urine, but Kassam pinched the tube a few inches above the tip of Caleb's penis, stymying the flow before the piss went too far.

"Present your cock like Caleb," Kassam told Leon.

The older lab did as he was told, mirroring his son, and Kassam repeated the process, feeding the free end of the tube into Leon's urethra, sounding him and penetrating down past his prostate and into his bladder--in effect, the father and son were connected with a double-ended sounding rod, and as Kassam released his pinch on the tube, Caleb's piss surged forward, streaming directly from the younger lab's bladder into his father's, refilling him with piss that was not his own, but had been made by his progeny.

Kassam watched the scene play out before him, stroking his throbbing cock to the sight of the panting dogs on the table, son pissing into dad, their knotted cocks connected so intimately by something he had done. But there was still more to do. Reluctantly, he stopped stroking and turned to the box he'd retrieved the tube from.

This time, he withdrew a black case that he opened--from the case, he pulled out two electro loops, both connected by wires to a control panel inside the case. Kassam reached into each canine's lap, scooping their balls up from the table and tightly cinching the loop around the base of the scrotum before letting the testicles plop back down to the table. When he finished, Kassam returned to the control panel inside the case and flicked on the power switch, activating the system.

"You two can squirm, moan, and cry if you want, but you're still going to sit there and take as much shocking as I give you," Kassam told the father and son. Without another word, he turned the dial to the low setting.

Both labs jolted with the flow of electrical signals that zapped through them--with their legs wrapped around each other and their cocks touching, Caleb and Leon completed the circuit for the current to flow through. It started as a steady, sweeping sensation that pricked through their testicles and the undersides of their shafts, and ran along the parts of their bodies that touched. Caleb panted and moaned softly as Leon breathed faster, his large stomach shivering at the new feeling.

"Oh!" Leon and Caleb cried simultaneously with a jump--Kassam had pressed a button on the control panel, switching to a pulse that hit Leon and Caleb at the same time, startling them both. The tiger grinned and turned the dial to the first intermediate setting, increasing the stinging intensity of each pulse that fired into the nerves of the canines. Each pulse felt like an internal slap to the groin, and both Caleb and Leon thrust into each other on each hit. Their cocks, still connected with the tube, jostled together; every twitch of Caleb's transferred to a light bob in Leon's, and Caleb couldn't control the stream of urine that still passed through the tube, depositing more of his piss into his father's bladder.

Kassam turned the dial to the next intermediate setting, just below the high voltage option, then pressed a button to turn the system to "audio"--electrical signals would be based on sounds that the mic on his phone picked up; the shocks to Caleb and Leon would correspond to how loud or prolonged the sounds were. Kassam picked up his phone and slowly paced back and forth in front of his workstation, watching the two dogs as he spoke directly into the microphone.

"Look at the two of you, helpless to do anything but sit there like the toys you are," he said, relishing the sight of Caleb and Leon squirming at the effect his words and the electrical signals had on them. "Both of you are so easily manipulated...dependent...playful...loyal. Everything a good dog should be. I bet you never thought you'd find yourselves in this kind of situation though, never in your wildest dreams."

As the tiger spoke, his voice grew louder, sending stronger and stronger shocks to Caleb and Leon's balls; Caleb pushed his feet back and forth uselessly, straining to take the treatment while Leon bucked up against his son.

"But those dreams are real, boys!" Kassam continued. "I have a lot more in store for you for your new lives as my toys! But to make that happen, I'm gonna need to do a couple things to you! You have to TRUST me," he emphasized loudly, "they're going to be for your own good. You might be a little scared in there--in that place wherever your minds still are. But you don't have to be afraid! I'm going to take good care of you to make you into something greater. You hear me?!" he nearly shouted. The whole time Kassam spoke, the canines whimpered and tears had formed in the corners of Leon's eyes. The tiger grinned and took a deep breath.

"You're going to be GRRREAT!" Kassam roared into his phone.

Caleb humped up hard, the tube connecting his cock to Leon's dragging his father's cock up with him. He howled at the pain as Leon clenched and bared his teeth.

"DON'T YOU CUM YET, PUP!" Kassam yelled with a smile. He watched as Caleb kept thrusting his hard cock into the air, and Leon threw his head back, howling with his son as the tears began to fall. Kassam roared into the microphone again, driving both dogs wild as they continued to moan and writhe against each other; the tiger imagined that Caleb's hole was clenching wildly on the dildo still trapped within him.

The tiger strode back to the control panel in the case and softly said, "Alright, let's bring you back down...down...down..." His voice decreased in volume until it was just a whisper and the electrical signals faded, but Caleb and Leon still bucked and twitched in the aftershocks and involuntary muscle spasms. In the silence (save for both canines still moaning), Kassam turned the dial on the control panel to the high voltage option and pressed the button for the "milking" setting. "Before we go back up!" he yelled as he watched father and son arch their backs at the same time, feeling the new sensation in their testicles.

The electricity behaved in a way that made it feel like their balls were being squeezed in tight grips, then pulsed slowly at first before going faster and faster, then stinging and becoming a constant current that rose in intensity--it was as if Caleb and Leon's balls were being milked by the most insane mixture of pleasure and pain they had experienced. They huffed, panted, moaned, lolled their tongues out, drooled, howled, hollered--everything they could do to express the feeling that drove them to higher heights of ecstasy and agony.

Kassam reveled in the sounds that the pair made; they could scream as loud as they wanted, but the soundproof basement walls would never reveal them to the outside world, not as long as he was in control.

After 15 minutes of nonstop torture and pleasure, hearing the Caleb and Leon yell themselves hoarse, Kassam decided it was time for their release. He reached a hand between their cocks, gripping the exposed tubing that still connected them.

"Cum for me now!" he commanded over their howling, snarling, moaning, and crying. Without waiting, he yanked the tube upward, pulling both cocks up towards the ceiling and dragging the piss-filled tube out of their bladders, back through their prostates, and out of the tips of their cocks with a loud slurp; piss dripped from the open ends of the tube and back down onto the canines and the table.

With the removal of the tube, father and son uncontrollably urinated on each other, drenching each others' groins, waists, stomachs, and legs as they continued to buck wildly against each other. Then, at the apex of the stimulating electrical current, and as if a dam had been demolished, twin explosions of white fluid gushed forward to join the translucent, pale yellow liquid--thick, ropy salvos of cum shot from both knotted cocks, landing goopily on dark fur and the metal work surface. Leon's orgasm was so powerful that multiple wads of cum splattered on Caleb's face, dripping off his muzzle and onto his tongue before dribbling onto his chest. Both dogs moaned mindlessly, their conscious selves far away from their bodies, lost in clouds of bliss.

"That's it, keep shooting," Kassam encouraged the canines as their cocks continued spasming, oozing more cum to join the mess. He swiped a finger through a puddle of Leon's semen and tasted it. "Mmm, perfectly salty." Kassam then reached over to Leon's stomach, where he scooped up a large glob of Caleb's genetic material. He dropped it on his tongue and rolled it around his mouth before swallowing. "You're sweeter than your old man. What'd you do, eat some pineapple earlier?"

Kassam chuckled to himself as he watched and heard both dogs continue to moan, unaware of his observations. Unable to help himself, he leaned over and licked the side of Caleb's face, his tongue wiping up a helping of Leon's cum.

The flows of semen eventually slowed as Caleb and Leon came down from their orgasms, and Kassam turned off the e-stim system and pulled the electric loops off of their testicles. Caleb and Leon continued to pant heavily as Kassam said, "Alright boys, let's keep it moving. Caleb, get on your hands and knees, facing away from your dad, and push out that toy."

Caleb, his stomach and chest still heaving, obediently followed Kassam's instructions, which culminated with him contracting his rectal muscles and pushing the silicone arm and fist out of him; it landed with a heavy plop in Leon's lap, bumping against the older canine's still-erect cock. Kassam picked up the toy and dropped it to the floor--he'd pick it up later when cleaning the playroom.

"Leon, start fisting your son."

With his tail wagging limply, Leon sat up on his haunches and scooted closer to Caleb's backside. He placed a bracing hand on Caleb's rump and squeezed his son's glute, as if subconsciously reassuring the younger lab. Leon then inspected the thick, puffed out lips that rimmed Caleb's hole, with his deep red insides visible within the circle of flesh. Leon tenderly rubbed his son's hole with his free hand before extending his fingers, keeping the shape of his hand smooth for entry. As he began to push, a thick coating of lube dribbled onto his hand and forearm--Kassam had opened a bottle and was squeezing its contents onto Leon. He rubbed the lube to evenly coat Leon's arm, and the older dog continued moving his open fist forward into Caleb's ass.

The loosened flesh inside enveloped Leon's large hand with ease, and Caleb's father sank in up to his wrist. He thrust back and forth, retreating enough to reveal his knuckles, then pushing back inside to his wrist. Kassam watched as Leon continued, going just a little further with each successive thrust until he was halfway up to his elbow in Caleb.

"Curl that fist and start punching."

Leon complied, taking care to sensually rub his fingers against his son's inner walls as he formed a proper fist. Caleb moaned as he felt the thick mass of Leon's curled hand inside him, and arched his back as Leon began to punch his guts, slowly at first and then speeding up to a rhythmic, wet back-and-forth.

Meanwhile, Kassam had moved around to the other side of the table and opened one of the drawers; he pulled out a pair of elastrator pliers and a small tub of thick, green rubber bands. As Leon continued to fist Caleb, Kassam hummed to himself and stretched a band over the prongs of the pliers. He looked up at Caleb, watching him pant and roll his eyes--still showing the hypnotically swirling colored rings--in sheer pleasure as his dad happily ruined his hole. Kassam gently patted the side of Caleb's face with his free hand.

"Remember, this is going to be for your own good," Kassam told him. He then reached under Caleb's torso, down to his groin, and held the loaded elastrator pliers steady. He tugged on his scrotum, getting it into position, and then used his fingers to maneuver one of Caleb's swollen testicles through the expanded green rubber ring. He repeated the same process with the second testicle, then pushed the rubber ring off of the plier prongs--in the blink of an eye, the ring was snugly secured around the base of Caleb's scrotum and began its work, cutting off the circulation to the lab's balls.

To speed up the process and minimize on the mess that was to come, Kassam added two more elastrator rings, so Caleb wore a total of three tight rubber bands that made his plump balls bounce with each thrust of Leon's fist into him; banded off from his blood supply, the boy's testicles would start to decay.

Kassam reloaded the elastrator and moved over to Leon; he watched with fascination as the older canine's cock continued to bob and bounce in arousal. Kassam rubbed a reassuring hand on Leon's stomach before he reached over and pulled the knotted cock through the elastrator ring stretched over the pliers. Leon's large knot bumped against the plier prongs and Kassam strained his grip, expanding the tight rubber ring to make more room; he managed to get over the bump of Leon's knot and pushed the ring deep into the canine's sheath, securing it around the musky root of his cock. Like he did for Caleb's balls, Kassam added two more tight green rings--as he did so and the blood supply to Leon's cock was cut off, his member looked especially swollen. Kassam playfully batted at the cock, watching it bounce up and down and marveling at the fact that while the dog's conscious mind was still fully aware of what was happening, it would accept the tiger's actions as something necessary, as something that had to be done.

Satisfied with his handiwork, Kassam replaced the elastrator pliers in the drawer; he left the drawer open, gazing at the other tool inside for a moment before he strode back over to his easy chair and plopped down on it; he reclined the seat and watched Leon continue fisting Caleb on the table. Kassam stroked his cock, running his thumb over his subincision and fondling the hafada piercings on his scrotum. With his other hand, he pulled on his nipple piercings. He watched for another twenty minutes, observing as Leon went deeper and deeper on his inward thrusts, with Caleb's stomach bulging outwards with Leon's fist. Eventually Leon got up to his elbow in Caleb, the joint just barely visible outside of his son's hole.

"That's it, go deeper," he called over to Leon.

Caleb grunted as his father sank his elbow and part of his bicep into him. Kassam licked his lips and stroked his cock faster before backing off, continuing to watch the show as Leon completely destroyed Caleb's ass, his puffy lips being drawn out each time the older canine pulled back. Pre welled up in Kassam's urethra, dripping down his shaft and leaking onto his balls. He ran a finger lazily along his cock, swiping up a thin line of fluid, and licked it off. This went on for another half hour, with Kassam edging himself in his easy chair and watching Caleb and Leon.

Eventually, Kassam decided that the time had come to move forward. He pushed himself out of his recliner and walked back to the worktable.

"Alright, let's wind things down. Both of you, present for me."

Leon stopped fisting Caleb and pulled his thoroughly wet arm out of his son's hole, trailing sloppy strings of lube. Together, the two canines repositioned themselves so their rears faced Kassam, and they reached back, raised their tails, and spread their ass cheeks to present their abused holes; while Leon's looked somewhat less messy, it was still damp and clearly showed its rough treatment. Caleb's was still sopping wet with lube, and his puffed out lips resembled his father's when he had first seen Leon present his ruined hole that afternoon--in Caleb's mind, it felt like it had happened so long ago.

"Show off," Kassam commanded.

As if synchronized with one mind, Caleb and Leon simultaneously pushed out their rosebuds, displaying their inflamed and engorged flesh for the tiger. While Leon's was brighter and bigger, Caleb's contained more folds and shone more wetly. Kassam fingered them one at a time, gently pushing on them with his digits, before he leaned down and licked over them--Caleb's was muskier than Leon's, but Leon's was much more supple than his son's. Granted, Caleb had only had his worked over for an hour, while Leon had had twice as long.

Pleased, Kassam smacked both of their asses. "Very good, boys. Daddy's very happy with you both. Now, face each other, get close, get up on your knees, and raise your hands up."

Father and son did as they were told, scooting close enough together for Leon's belly to press against Caleb's and his now-dark purple elastrated cock rubbing against his son's free penis, while Caleb's plump balls hung against his father's low-hangers.

"Let's scoot you back a little, here," Kassam instructed Caleb, guiding him to scoot back so his upward reaching arms were positioned under one of the hooks embedded in the ceiling; Leon was already positioned under another hook.

Kassam opened another drawer in his table and withdrew six loops of coiled, red rope. With the first loop, he diligently tied together Caleb's wrists, tossed the free rope over the hook in the ceiling above, pulled it until it was taught, and then secured the remaining rope in a tight knot on one of the brackets under the table. Kassam repeated the process for Leon, securing his wrists to the hook in the ceiling, then tied the older canine's ankles in a way that they were forced apart, spreading his legs. Finally, Kassam restrained Leon's waist--with all the ropes tied in place, the dog wasn't going anywhere; he could struggle, but there was no way he'd be able to stand or get away from his current position on the table. The tiger performed the same process for Caleb, spreading and restraining his legs and securing his waist; both father and son were trapped thanks to the six ropes and Kassam's knot-tying skills.

Kassam then sauntered around to the drawer that he had left open, where he pulled out the tool he had been waiting to use; he held it by the leather sheath and then took his position between Caleb and Leon.

This was the opportune moment: "Freedom granted, run while you can," Kassam said, using his code phrase to release the conscious hypnosis on Caleb and Leon. However, the mental conditioning that had been engrained as the two canines were put under--as well as any suggestions that the tiger had told them while they were under--would stay in effect. The concept of a safe word like "watermelon" wouldn't even cross Caleb or Leon's minds.

The swirling rings faded from their eyes, and it was like a thick cloud lifted from Caleb and Leon's minds as they reconnected with their bodies; they slumped in their restraints and were suddenly aching, thirsty, hungry, exhausted, and aroused beyond belief.

"Oh fuck," Caleb moaned, experimentally pushing out his rosebud. "Oh fuuuuuuck..."

"God damn, what'd you inject us with?" Leon groaned, looking down at his swollen cock. He panted, "Are...are you gonna take these rings off?" He swallowed, his throat dry, and turned to look at Kassam. Then, when he saw what was in Kassam's hands, he felt a lurch in his stomach.

"Wha-what are you doing?" Leon spluttered. "You did so much, I--"

"You're going to be fine," Kassam said over him. He gripped his tool by the handle and slowly pulled the sheath off, revealing a sharp, gleaming Bowie knife. "You might think that you don't want it, but you know that you need this."

The reflected light caught Caleb's eye and he finally saw the knife, too. "Oh, what the fuck?" he muttered, feeling his heart rate go up.

"The chemicals I gave you also increased your pain threshold," Kassam continued calmly as he placed the knife sheath to the side. He stroked Leon's leg. "This is going to be a walk in the park for you. Like I said, you don't have to be afraid."

Without another word, Kassam reached for Leon's elastrated cock; he wrapped his fingers around the base of the canine's knot and pulled, exposing the root of the cock. Kassam rested the blade of the knife in between two of the elastrator bands. Leon's stomach shivered and he looked up at the ceiling, whimpering.

"No, no, no, please, don't!" Caleb yelled, struggling to move closer, but his restraints held him fast.

"It's okay, you're going to be just fine," Kassam said soothingly to Leon. "Remember what I said? Take a few deep breaths and remember."

Leon tensed and struggled against his wrist restraints, starting to panic, then slowed his breathing, trying to keep a clear head--and there it was: he remembered that he needed this, that it was for his own good, just like the tiger said. His struggling settled--he still pulled against the tight rope around his wrists, but there was no point. He knew what was going to happen, it was just a matter of when.

Kassam moved when he felt Leon start to relax; without further ado, he sliced through the tight flesh of Leon's cock, cutting through the root and separating his penis from his body. Leon felt no pain, just an absence of sensation from his sensitive cock, an emptiness that somehow felt...better than before, like a heavy weight that had been lifted from his mind. Caleb gawked at the scene, his jaw open.

"There, all done," Kassam said, hefting the large cock in his hand; the elastrator band still on Leon's disembodied cock and the bands still on his stump prevented all but a few drops of blood, semen, and urine from leaking out. Leon's sheath, now empty, folded back over, hiding the stump from view. Leon exhaled slowly and looked back down, fondly wishing his cock were still attached, but as he gazed on the organ sitting in the tiger's hand, he realized it was no longer his cock to use: it was Kassam's, it would always be Kassam's, it had been Kassam's from the moment he stepped into the playroom. Leon had just been the one to wear it and use it at the tiger's command. "Not so bad, was it?"

"No, Sir," Leon breathed. "Thank you."

"Good dog." Kassam beamed up at him, then put the cock down on the table. He turned to address Caleb. "Alright, pup, your turn."

Caleb tried to scoot away from the tiger, but to no avail, as the ropes held him fast. Kassam easily reached over and took the boy's balls in his hand and rested the knife behind them.

Caleb started to whimper, hyperventilate, and shake his head, refusing to believe what was happening.

"Cal, Cal, look at me," Leon called over to him, getting his attention. Caleb looked up into his father's eyes. "It's ok, son, just look at me, keep looking, you don't have to watch," Leon told him. "Remember..."

As he stared into his father's eyes, Caleb began to remember the tiger's words and how much sense they made. Yes, this was necessary, he needed it to be done. And the tiger was performing the procedure, he was taking the time to do this service himself...

With a quick, forward slice, Kassam cut through Caleb's scrotum and both vas deferens, severing his testicles; he brought the swollen balls away, the sack still closed thanks to one of the elastrator bands still tightly banded around the top. The nub where the base of Caleb's scrotum had once been let only a few drops of blood fall to the table, the remaining rubber bands keeping the skin and blood vessels shut. Like his father, Caleb felt no pain, just the absence of pressure, as if something had been holding him back and now there was just nothing there.

"Good job, pup," Kassam told him. "Nothing to it."

"Thank you, Daddy," Caleb found himself saying.

"Of course." Kassam lightly tossed the ballsac in his palm, smiling up at Caleb. "Although you've had me curious for a while..."

Kassam put the knife down and carefully pulled the elastrator band off the top of the severed scrotum; he held it so the scrotum stayed intact, like an open bag containing a pair of nuts, and he reached in with a delicate claw and pulled out a testicle by the remaining length of vas deferens. Caleb watched as the pinkish red organ was lifted out and gingerly licked by Kassam's tongue; the tiger wrapped his tongue around it and sucked the testicle into his mouth, still keeping a tight grip on the cord connected to it.

"Mmmmm," the tiger moaned before letting the ball pop out of his mouth and dangle from his finger again. "Yeah, definitely tasty. My little project is going to enjoy you a lot."

"Project?" Caleb panted as Kassam replaced the testicle in the scrotum and pinched it shut again. "What project?"

"It's what this whole thing is about," Kassam answered, picking up the cock that still lay on the table. "I had a little side project from work that got me thinking what I could do with the chemicals I synthesized..."

He continued as he walked over to the table next to his easy chair, where his phone sat. "I also might've gotten a little inspired by a monster movie here and there. I didn't think I'd actually get anything out of the experiment, but I thought, hey, what's the harm in trying?"

With his free hand, Kassam picked up his phone and tapped a command into it; the cluster of cylinders rotated until the sixth cylinder came to a stop at the front of the cluster's housing, and the tube in the ceiling connected with the housing. "So, I started with one, then two more, and that's when I realized how it likes the routine to go."

Kassam pulled open the door to the built-in cabinet for his side table; initially, Caleb had thought that there might be lube and towels or maybe more porn stashed away inside, but instead he saw that there was another tube that fed into the floor, like a vacuum transit tube used at a bank. Kassam deposited Caleb's testicles and Leon's cock in the chamber above the tube, then tapped a button on his phone app.

The vacuum inside sucked the genitals away, down into the floor, and Kassam looked up at the ceiling; Leon and Caleb, still restrained, followed his gaze. After a few moments, the cock and balls emerged in the tube that fed from the ceiling into the cylinder housing, and they disappeared into the connector joint. Kassam looked at his phone, swiping through a set of graphs that showed different readings, then nodded to himself. "Yep, I was right, both of you really have it going now. Never seen it eat up so fast."

Leon and Caleb looked at each other, confused. Kassam looked up at them with a smile on his face. "I think we're ready to get you on your way. You're going to be great additions."

Before Leon or Caleb could say anything, Kassam tapped on his phone again and the metal sheeting over the cylinder folded up into the cluster's housing; in the clear cylinder within, a mass of thick, orange, translucent, shimmering slime roiled against the glass walls. Caleb and Leon's eyes widened at the sight.

"This is the slime I've been working on," Kassam explained. "And it's excited to have you join it."

With that, he tapped on his phone once more, and the slime was sucked out of the cylinder and into the tube that connected the housing with the ceiling. With trepidation and some level of their own excitement, Leon and Caleb watched the tube in Kassam's table: sure enough, after a moment, orange slime began to appear and force itself out of the tube, expanding away from the table and almost unfolding itself further into the room. It curled around Kassam's feet, massaging up and down his legs as more and more of it emerged from the tube. After another minute, the slime was completely out of the tube. It completely enveloped Kassam, actively submerging the tiger in a gelatinous column of orange, before it bent over and gently unloaded him into his easy chair. Kassam leaned back and settled further into his seat as he watched the slime begin moving toward the worktable.

"I suggest you two start making out," Kassam advised. "Makes the experience more enjoyable. And don't worry about breathing, it's highly oxygenated, so you're not going to drown. Just let it in."

Caleb and Leon watched as wave after wave of orange slime fanned out and rippled toward them; translucent tendrils twisted around the legs of the worktable, surging forward and upward to the two canines, and the slime pooled onto the table before it circled around and between them, as if deciding who to focus on first. Caleb's eyes darted, trying to follow the slime as it moved, but Leon calmly leaned toward him, his eyes on his son's; Caleb's gaze settled on Leon and, on instinct, took his father's cue and leaned in to meet him, his muzzle pressing against Leon's in a deep kiss. Tongues wrapped around each other and glided over teeth, breath exchanged places with breath, saliva swapped mouths, and for Caleb and Leon, nothing else mattered but the pleasure they shared.

The slime settled around Caleb, closing in on his legs first; as the slime made contact, Caleb felt a warm, tingling, heavy pressure, as if a weighted blanket was being laid over him. He kept his eyes shut and breathed deeply, choosing to focus on the pleasure of making out with his father, not thinking about anything else happening. Meanwhile, the slime continued to envelope him in a full-body embrace, extending up his legs, around his stomach and torso, slipping into his ass and urethra, climbing up his arms, and wrapping around his head, penetrating into his ears, eyes, and nostrils, down into his esophagus and lungs--the slime left his mouth alone for the moment, allowing him to continue making out with Leon.

The sensation of complete penetration was actually enjoyable; there was no discomfort, just a gentle pressure, like being hugged from the inside and outside, and a warm tingle that slowly heated more and more to the point that it felt like Caleb was wrapped in the most comforting and inviting campfire. Slowly, gradually, Caleb's body began to dissolve into a jelly-like substance, discorporating from his feet first. By the time his chest started to soften, his feet and calves had completely disappeared, merging with the slime; the ropes that had been bound around his ankles now laid uselessly on the table. Caleb continued kissing his father as his body dissolved further. The ropes around his waist and wrist slackened as they pulled through the gelatinous consistency of the slime, and Caleb felt as if he was perceiving both the darkness of his closed eyes and the fully-lit scene of what was happening in the room. He didn't know it, but parts of his brain function were shutting down and transferring over to the slime as it converted him into part of its mass; Caleb was still Caleb, but he was also becoming a part of a larger, multi-minded organism that perceived everything around it. His mind was taking in and processing data from two different sources, he just needed a moment to adjust.

After another few minutes, Caleb's muzzle began to soften. When Leon felt the change in consistency of the tongue he'd wrapped his around, he opened his eyes and pulled back from his son--he faced the mound of quivering orange slime, and all that remained of Caleb was his mouth and tongue. Paternal guilt, regret, and shame stabbed through his heart--his boy was gone, lost to him, all because of their lust and a tiger's science project. Anguished tears welled up in his eyes and he felt a lump in his throat.

"C-Caleb..." he started, but he couldn't continue.

On some level, Caleb must have realized he was no longer gently kissing his father and perceived Leon's emotional state, as the mouth--still changing into slime--softly said, "I love you, Dad. Don't feel bad, thank you for everything we've done. I enjoyed this, it's so warm in here, and it doesn't hurt. I think you'll like it. You'll see me soon."

At those words, Leon's heart fluttered, and in the combination of grief and joy and yearning to be with Caleb again, he closed his eyes and leaned his head forward again to meet the now fully gelatinous representation of his son's muzzle. The slime met Leon's kiss and a larger maw, with teeth made of jelly, pushed out and closed over the older lab in a warm bite that washed over him. Leon breathed in, relaxing as the slime filled every part of his body, and Kassam watched for a few minutes as the canine's outline faded more and more--eventually he completely integrated with the slime, feeling the same sensations that Caleb had as he melted away and disappeared, absorbed by the slime.

In his preserved and still functioning consciousness, Leon rolled into a warm embrace with Caleb, perceiving his arms and legs wrapped tightly around him. Caleb held his father close while Leon ruffled the fur on top of his son's head, conveying that everything was alright, that they were perpetually together in this safe, inviting space, that that was all that mattered.

In the playroom, Kassam watched as the slime roiled and coiled on itself, reveling in the two new minds it had absorbed, allowing them time to recognize just each other as familiar presences within the slime. Kassam noted that his creation was behaving consistently--each individual that the slime absorbed needed a moment to have their identity reflected in the slime's movements as they adjusted to this new state of being before joining with its hive identity. There were individuals within the slime, but it also operated as a gestalt consciousness, and it would grow more and more with each mind it consumed. If Kassam had to guess, he thought that father and son were hugging each other tightly.

"Alright, let's test you out," he said to the slime as he sat up in his chair. "Show me Leon and Caleb."

The slime quivered for a moment before separating into two and forming gelatinous representations of the two labs, with Leon's cock and Caleb's balls intact once more.

"Malik."

The labs merged together and reformed into a tall, heavyset bear.

"Scott."

The bear grew taller and beefier with antlers, representing a moose.

"Jalen."

The moose shrank, the horns curled, and the slime transformed into a ram.

"Henry."

The ram became a wolf.

"Darrien."

The wolf turned into a ferret.

"Eli."

The ferret became a rat.

"And Victor."

The rat turned finally into a lion with a full mane. Kassam's gaze lingered upon this last apparition, the memories starting to flood back. He took a breath and pushed them away; as if sensing the tiger's response, the slime deformed into a shapeless accretion once more, writhing and waiting for a command.

"Okay, you know what I want," Kassam told the slime--he leaned back again and spread his legs.

In a flash, the slime arced down from the table, seeped across the floor, and formed a multi-tentacled mass in front of Kassam. Tentacles wrapped around Kassam's arms, legs, and waist, picking him up high in the air. More limbs of slime found their way into the tiger's mouth and ass, filling him tenderly and fucking him from both ends. The slime threaded tentacles through his nipple piercings and tugged, while another tentacle wrapped around his testicles and pulled on his piercings. The slime extended more and curled a tentacle delightfully around his cock before it slipped into his subincision, stroking at the internal flesh for a moment before it pushed further down his urethra and pounded against his prostate; from there it slid into his bladder. Kassam moaned in abject pleasure, grateful that the tentacle knew just how to please him. He looked up, his eyes pleading for more.

The slime acquiesced; it delicately wrapped a tentacle around his throat, forming a leash and collar that lightly choked him, just how he loved it. Inside his stomach and ass, the slime pushed outward, forming bulges in his torso that roughly pounded him; his prostate was being milked relentlessly, and with all the other sensations of what the slime did to him, he was finding it hard to keep himself from cumming. But after 10 minutes of the treatment, he couldn't stop himself--Kassam roared and saw stars as his orgasm finally hit him. He spasmed and arched his back, exposing himself more and more to the slime as his cum was collected in the gelatinous tentacle that was filling his cock. The tiger's cum traveled down to join the slime's main body as the tentacle withdrew, and soon the tentacles filling his ass and wrapped around his balls followed suit, rejoining the rest of the slime.

As he panted heavily, Kassam looked up at the slime again and saw what he was most excited for: around his cum that visibly floated in the living sea of orange, more streams of white fluid formed--genetic material from all nine of the consciousnesses now housed within the slime gathered together, mixing with Kassam's cum. He was glad to have used the shots of his blend on all of his prey; within the slime, everyone had produced enough cum to contribute to a solid mass the size and volume of a kiwi egg. Kassam watched as the egg floated upward to the tentacle connected to his mouth, and excitedly saw it travel down the length of the tentacle. His jaw was forced to lower because of the size of the egg, and he relished the sensation of the tentacle forcing it down his throat. He closed his eyes, content, as he felt the egg finally settle thickly in his stomach.

The slime, sensing how satisfied Kassam was, gently lowered him back down into his easy chair and released its grip on him, withdrawing the tentacles back into its mass.

"Mmm, thank you, thank you all," Kassam murmured. "Now, it's time to go home and go to sleep."

On cue, the slime coalesced and submissively rolled down to the floor as it streamed back to the tube from which it had emerged. It entered and pushed itself further down until it reached the cylinder. When it had completely filled its container, Kassam tapped the button on his phone's app to lower the metal sheeting, letting the slime know it was time to simmer down. He would have more fun with it soon, and he would add even more minds to it before too long.

---

It was dark and yet Caleb and Leon could see everything; their senses extended beyond just sight, touch, smell, taste, and hearing. They could perceive the seven other minds in that space with them, where there was both room to move and breathe and so little room that they were on top of each other in an orgiastic arrangement of bliss. Caleb's mouth was filled by a passionate bear's tongue, and so comprehensive was the embrace that he couldn't tell where he began and where the bear ended. Leon was caressed by a ferret and a moose who both penetrated him as they kissed a rat who fucked the bear who was also hugged by the lion who was being eaten out by the ram who was being pleasured by Leon--the collective of minds fueled its own lust as they settled into the dark, passing their consciousnesses between each other, occupying themselves as they waited for the tiger once more.
