Zach stumbled off the bus into the unforgiving southwest sun. He blinked, squinted, and pulled on a pair of sunglasses, as the growing crowd finished their 4 hour drive from the airport to… where ever the fuck this was. The parking lot was mostly deserted, leading up to a locked heavy metal gate, and large earth filled bags that made up a wall, stretching out in both directions. A few more buses pulled up, disgorging their riders, then drove off for another loop, ready to bring a few hundred more people to… Camp Kris, according to a sign over the gate.

A fairly tall lupine in dusty fatigues walked over and shouted, “All soldiers, line up by serial number. It’s not that fucking hard, you just need to look at the person in front of you’s dog tags and figure out if you’re in front or behind them. Then fucking go from there.” The crowd scrambled to try to obey, making a vaguely sorted box after a few minutes. The gate ponderously opened and the most simultaneously boring and terrifying day of Zach’s life began.

It was called indoctrination for a reason. Head shaved, gear issued, lines waited, shots given, teeth inspected, more lines, paperwork processed, groups broken off as they were pushed into their training units. The only time he sat down was when he took off his old fatigues and put them, and his phone, into a box with his name and identification details on the front, pulling on a loose paper robe and cheap sandals instead.

The trainees shuffled into an auditorium, where a person in scrubs waited in front of the projector screen. When they shuffled in and sat down, a few sets of knees audibly cracking as they could relax a bit, she cleared her throat and advanced the slide.

“Military Authorized Trophic Infection” read the screen, with a slightly… overly enthusiastic picture of a maw with sharp teeth licking its lips.

“Who here has heard about the Bite?” She asked. Nobody raised their hands, still slightly too shellshocked to respond.

“Alright, who hasn’t?” Same response. She sighed. “The Bite is a legally authorized infection by existing morphs. It is intended to get you through your training and any deployments alive. You’re going to need to sign a series of release forms and waivers stating you understand and consent to this process. If you choose not to, you will remain on base while your transfer is processed.” That got a reaction.

There were a lot of horror stories about what happened when uninfected humans spent too much time around morphs. A lot had been disproved, but… it had cultural cache. At the least with a supervised bite, you knew what species you were coming out the other end. People hurriedly signed their names, barely paying attention to the details. Something about hormonal changes, musculoskeletal growth, personality shifts… for all that the MATI program had been sold to the public as a game changer, and the number of vets back in society… it was still a lot more rumor than anything solid. Most people just knew about them through headlines and maybe a videos online. The attempts to use spokespeople who had gotten the treatment ended up being restrained and limited, their voices and appearance deemed too… different to receive much public airing.

Still… Zach blushed… it wasn’t like they weren’t attractive. One of the equines was standing nonchalantly off to the side, her thighs thicker than his torso, chest straining her top, all 8 feet of her built to the point that her clothes barely did anything to hide what was underneath. He blinked and tried to refocus on the forms as the person in front started droning again.

“You’ll see on the last form your intended job. This is a training environment so if you fail to meet standards, you’ll be reassigned.” Zach hurriedly flipped to the last page.

Scouts, Cavalry. His neighbor looked over, and pointed to his own assignment. Scouts, Warpack. They looked at each other and both shrugged.

“You’ll be called up here by assignment, given an IV drip to help you with the bite, and have your paperwork checked. If there are any issues, we’ll go over them and give you time before anything irreversible happens.”

The medic stepped off stage, and the slow process of moving everyone through the medical treatment began. The room was kept dead silent, everyone sitting with their thoughts, until they were called up. Zach tried reading the medical information, but his eyes kept going unfocused. The bus ride had boarded at 4 am, erm… 0400, and he’d always found it hard to fall asleep on those. Unlike his neighbor, who had snored the entire time.

He stared off into the middle distance until everyone in his row stood up. He followed them out the door and into a tiled hallway that had the tang of medical grade disinfectant. People, humans and morphs, in medical scrubs took over, carefully checking the paperwork and leading people towards their specific bite prep.

Zach followed the path towards equines, leaving his eagerly vibrating wolf pack groupie, and sat down in a padded chair.

“How are you feeling?” A kindly sounding person in scrubs, a face mask, and hat asked, carefully moving a barrel into position.

“Umm… a bit worried about being able to move if that’s what’s going in me.” Zach said, staring at the 55 gallon drum.

“Oh, this? It’s not all for you, but you all do take more than most, so we need frequent resupplies. Any questions about the procedure?” The medic carefully examined Zach’s arm, wrapping a tourniquet around it.

“Umm… all of it?”

“Ok, basically this is just to make sure that your body has enough sugars, fats, and proteins not to literally eat itself alive. You’ll be grouped with your scout team, and you’ll be infected. The process is a bit variable with the group you’re a part of. I know that the wolves like doing a bonfire. It just depends. Any bodily fluid to blood contact is sufficient. Bites are the easiest way to spread the infection, but there are other methods.” He found a large enough vein and started prepping the injection site with alcohol.

“… and then what?”

“A relatively poorly studied experimental genetic virus adds a couple chromosomes to your cells so fast that your immune system doesn’t reject your body. Though it does trigger an endorphin cascade to stop you from ripping off your own skin, so people say its a good time.” He laid out a number of tubes, attached to IVs, each one marked by a number.

“… that’s … worrying.”

“But, hey, free abs and your dick will get bigger.” He attached a needle to the ends of each of the IVs, and made sure that the main tube was clear and ready.

“I can’t tell if you’re trying to reassure me or terrify me?”

“What do you want out of this discussion? Comforting lies, discomforting lies, the truth, or me being wildly unprofessional?” He picked up the needle, examining it carefully.

“Umm… Unprofessional?”

The nurse grinned wolfishly and leaned in. “You’re going to make a sexy stallion.” He pushed the injection into Zach.

***

Zach’s head was swimming happily, a mix of nutrients, magical medical goo, and military grade… presumably steroids had left him grinning happily on the table, as the medic walked off to process the next person. The machine next to him beeped, and another medic efficiently removed the needle and bound the wound.

“How are you feeling?”

Zach giggled. He was floating a bit. He shook his head. “Honestly… pretty good? Sorry, just… zoned out a bit.”

“No problem. You feel good to walk?”

“I think so…”

“Alright, up you get.” The medic said, helping Zach to his feet. He stumbled a bit then managed to stand upright.

“Alright, what’s up now?”

“You meet your new team, and training begins tomorrow morning.”

“… this seems abrupt.”

“Yep! We find the best way for people to adapt to new situations is to load everything on at once.”

“… doesn’t that cause burnout?”

“Everyone who makes the decisions has gone through it and hasn’t burnt out.”

“You know what? I’m not going to argue here. Can I just go pass out in whatever barracks I’m assigned to?”

***

As the truck drove away, it turned out not to be barracks, but instead a tent. A very large tent. Zach tried to figure out how to get the attention of whoever was inside. It felt weird to just… like barge into a place where you don’t know anyone. He hesitantly reached to knock, but didn’t, since it wasn’t like… a door, just a flap.

“WHY ARE YOU JUST WAITING OUT THERE?!” Someone roared from inside. “It’s like you’re poking my amygdala by not knocking.”

“Relax Anda.” A calmer, deeper voice said. “They’re probably just scared.”

“Why would anyone be scared?” Anda, presumably, said in a huff. “Ugh… fine Mustang, get off of me and let’s check.”

A few thudding heavy footsteps later, and the door to the tent unzipped, revealing the two figures inside.

They were clearly male and female, towering over Zach, probably about 8 feet tall. Zach’s eyes went wide as he took them in, and his nostrils flared at their potent musk, sweat dripping off their bodies as they looked at him.

They were both hooved, with thick powerful calves, defined thighs, wrapped in sheets that were just transparent enough to show everything. Zach’s mouth fell open at the veiny firehose like shadow beneath the sheet, bulging out beneath his knees, in front of cantaloupe sized balls. Anda’s curves, her head sized breasts, thumb thick nipples, thick hips, narrow waist, and defined abs grabbed his attention nearly as much. He swore he could see her slit and clit, inhumanly large and bulging between her legs, almost putting him to shame.

Mustang was mostly chestnut, with a white splotch on his face, his equine muzzle smaller than you’d expect on a horse, retaining some human features, while Anda was a tan color.

Both were strongly muscled, clearly showing beneath their short fur, their manes braided, tails flicking beneath them, wanting to get back to their previous activity, but to Zach, there was one overriding aspect. They were hot as fuck.

He looked further up and blushed hard, both of them staring at him, one amused, one annoyed. “Well?” Anda asked, raising an eyebrow.

“Umm…” Zach said, holding out the orders paperwork, trying to ignore the familiar rush of blood between his legs. She took it and quickly read the paper, then sighed.

“Alright, you better come inside. Sorry about the mess… you caught us in the middle of something after a run.”

The room wasn’t quite a wreck, but there were sweaty clothes on the ground, some stuff knocked off the counters, and a very wet bed with towels on top. The room reeked of cum and lust, and it didn’t look like either of them were planning on getting into something more presentable. There was a stepladder up to a table, and the other two sat down at it. Zach followed.

“So…” Zach trailed off, trying to ignore his persistent erection. Mustang held up a finger and closed his eyes. He breathed out, and started shrinking. It felt slow, but it was clearly visible, his muzzle retracting into his skin, his fur receding, muscles shrinking, until he was a heavily built powerlifter with a mohawk, sitting at an over-sized table next to an equine goddess. Zach resisted the urge to look underneath the table to see what had happened there.

“So, you’re now working with us for at least the next 3-ish years. We’re not going to force you to do anything with us so… there’s three options in front of you.” Mustang said. “One, you don’t want any part of this. You can get reassigned to a non-combat unit. Two, we find a different barracks for you. We’ll give you the bite, you live normally. Three, you live with us. No pressure in any way, but the housing is a bit better than you’ll find in a barracks room.”

“And there’s a fourth option.” Anda smiled, pulling her sheet off and leaning forward, both breasts on the table. “I’ve been wanting to be fucked in both holes, and you’re pretty cute.”

“Third option implied fourth option.” Mustang said. “Anda just likes to be explicit.”

“Sure, it took me 6 months of ‘accidentally’ running into you in the showers for you to finally get the hint.”

“Ok, yes. I am absolutely oblivious.” Mustang said.

“…” Zach sat there blinking.

“Aww, I think we broke him.” Anda said.

“Umm… you’re sure you want me?” Zach asked after a few seconds.

“Sure, nice build, nice face, nice dick. You seem respectful, and we’d be working with you anyway. Plus the Bite gives us a lot of leeway for how we infect you.”

“… what do you mean?”

“You ever get a blowjob from a horny mare?”

“… no?”

“Let’s get some food ready and have a good time together.”

Zach blushed, his dick harder than ever, tenting the hell out of his paper robe. Mustang led him over to the oversized couch in front of the TV. He was still… big, but Anda walking around as a full equine, towering over the two of them… that just felt different.

The two sat down, as Mustang booted up some party game, chatting with Zach about nothing, his hard dick on full display, his legs splayed out to fit his softball sized nads. Zach took a controller, eyes glancing over to the musky shaft that draped over the werehorse’s thigh. It… barely looked human, throbbing, pinkie thick veins running along it, it’s head blunter than a human’s, with a thick ring in the middle. The foreskin seemed a bit unsure if it was supposed to just cover the glans or to act as a sheath, pulling down further and exposing the ridge that surrounded the head to the air, dripping pre every few seconds. The urethra was visibly open, clearly intended to allow a lot of cum out at once.

His balls were in a smooth hairless pouch, apparently straining it a bit, and his pubic hair was more like horsehide, plastered to his body, though that could have been the sweat and musk. A couple veins radiated from his dick onto his abdomen, clearly needing more blood than his body could provide otherwise.

“Umm… how big…” Zach trailed off.

“In this form? About 6’3”, nearly 250 lbs. Something like 5% body fat.” Mustang said, showing off his biceps and veiny… everything. “When I relax into full equine, nearly 9 feet and close to 500 lbs.”

“Umm… and your…” Zach blushed hard, gesturing at the shaft that was dripping between them.

“You want to guess for me? I haven’t measured in a while. Sort of stops being relevant when…” He trailed off, smiling at the amazon bending over the table, showing off her ass and dripping slit, his dick surging between his nipples at full harness.

Zach blinked. “Umm… can I touch you?”

“I’d love it if you would. Can I touch you back?”

“Yeah….” Zach almost moaned.

“Let’s get that out of the way.” The paper gown fell to the floor a little later, revealing a slim swimming toned body, but nothing that special. Zach blushed again at Mustang’s eager eyes and smile. “Come on, I want you to guess how big this thing is.” He gestured at himself.

Zach walked forward on his knees, head swimming in the man’s musk. One hand hovered near the thick shaft, and slowly touched the spire. It was wet, hot, and begged for more. Another hand joined, barely covering half of the shaft. Zach slowly ran his tongue up the monster, savoring the salty pre.

“Fuck… is that how you always check something’s length?” Mustang asked, his toes curling, as he tried not to let his tail extend.

Zach didn’t answer, playing with Mustang’s medial ring, loving his gasps, and following a thick vein up to the blunt head, before sucking more pre from the source. He was starting to feel hot and tingly, his ass empty and needy. “Umm… fourteen inches?”

“Not bad.” Mustang said. “You ever taken something like that?”

Zach lay his elbow against Mustang’s hip, and compared the shaft to his forearm. They were nearly the same length, but the shaft was somehow thicker. “Dude, I don’t fist myself down to the elbow.”

“You want to?” Mustang offered.

“… a bit… but I am fucking horny and half drunk on your smell.”

“You want to be full drunk?”

“…” A few moments later, they were in a sixty-nine position, Zach’s nose shoved into Mustang’s groin, as Mustang slowly started licking Zach’s ass, gently playing with his balls and achingly hard shaft.

Zach’s face was slowly being covered in pre, as it leaked down the massive spire, his ass slowly being spread by Mustang’s eager tongue and fingers.

He gasped and his ass tightened around Mustang’s face when Mustang slowly started playing with his prostate, easily milking an orgasm out of the overstimulated human. Mustang’s saliva felt warm and he could feel wherever it had hit, his sensitivity spiking as it sank into his skin, his hole loosening around Mustang’s fingers.

“Fuck… you’re really good at this.” Zach managed, slowly recovering, before Mustang pushed him to gasp and shudder through another orgasm.

“Fuck yes I am.” Mustang said, playing with Zach’s balls and prostate, expertly milking him towards another blast over his chest. Zach’s prostate seemed to swell with each blast, becoming more sensitive and bigger, a larger target for Mustang’s tongue and fingers, as his asshole slowly pushed out into a doughnut, aided by nips that just accentuated the pleasure.

“Aww… you two started without me.” An amused voice said, putting three massive jugs of… something on the nearby table. Zach looked up from his new toy and saw a horny furry werehorse dripping, tail lashing, lust in her eyes and flooding his brain through his nose. She sat down in front of him, leg along the couch, gently cupping his head.

Mustang pulled back, and moved behind him, leaving Zach pinned between the two. Abs on his ass, massive dick running up along his stomach and chest, and a fuzzy dripping slit begging to be licked, with a massive throbbing clit.

She slowly pushed him forward, and he eagerly started licking the dripping snatch, head swimming in musk and earthy sweetness, as Mustang fit another couple fingers into his gaping asshole.

“You ready?” Mustang asked, as a massive fist-sized blunt head pushed at his entrance.

Zach managed a “yes, fuck yes” and Mustang pushed forward. Zach’s eyes went wide as his prostate was crushed by the battering ram filling his ass, and he unloaded onto the couch, gasping against Anda’s winking slit.

“Come on, cute stuff, don’t stop licking because you have the best dick in the state. You’re never going to get anything done if you can’t work around him.” Anda said.

Mustang laughed, and pushed in a bit further, pressing against Zach’s back and licking his neck. “Tell me when you’re ready for me to keep going. I know I’m a bit of a pain in the ass.” He chuckled, one hand grasping his shaft, fingers not even able to wrap around it.

“God, you are awful.” Anda laughed. “And you’re doing great.” She murmured, stroking Zach’s hair, pressing him harder against her clit.

Her earthy taste filled his mouth and nose, burning sweetly down to his achingly hard dick. As he kept licking, it felt it was somehow invading his mind more, pulling him deeper and deeper inside. Finally, he pulled away, gasping, and got pulled into and eager kiss, their tongues happily fighting, both of her flavors complementing each other.

She pulled away, kissing his forehead, playing with her nipples, as he panted, his tongue drooping out of his mouth below his chin.

“Wha?” He asked touching his tongue. He tried to draw it back into his mouth, but it was… really big, and felt like it had a mind of its own, wrapping around his hand and wrist, sending a lot of new sensations and tastes to his brain.

“Oh, yeah, it’s going to be a bit awkward until your muzzle comes in.” Anda said, demonstrating how long her tongue was. “Really fun for sucking dicks, bit big. You want to put it to good use though?” She said, pressing her hand around her thumb thick clit, her slit winking again and blasting him with the scent of pure sex.

Zach didn’t even try to fight it, diving back in eagerly, his tongue and mouth attacking her clit, licking her g-spot at the same time. She arched back, thrusting against him, hands squeezing her nipples as her gasping moans filled the air. She came with a happy cry, spraying him, and slumping back, reveling in the afterglow. Zach snuggled into the warmth, letting her recover.

Someone else behind coughed. “You ready for me to keep going?” He flexed his abs, lifting Zach up and making his eyes widen.

“Yeah… just slow… you’re fucking huge.” Zach managed. Mustang patted his ass and slowly thrust in, giving Zach time to recover before each additional thrust. He was big enough there wasn’t really… skill. Every movement and vein just ran over Zach’s prostate and stretched him that much more. Zach gasped as he felt his ass stretch again. “Fuck… I can’t believe I took all of that.”

Mustang looked really proud. “Nah, you’re about halfway.”

“What the actual fuck?!” Zach yelped, head and chest jerking up and pushing a bit further back onto Mustang’s medial ring.

“I’m part horse.” Yep, that was a smug sounding stallion. “Though…” Mustang said, stroking from base to head, “you’re getting there too.”

Zach looked between his legs, and saw a noticeably larger dick between his legs with much fuller balls. He was dripping pre and spurts of watery jizz were being forced out with each movement in his ass. “… shit…” He said, trying to relax and take the massive invader, as Mustang started to rock back and forth. He could feel warm spurts into his belly, bliss radiating from his pummeled prostate and dripping cock, sparks going across his eyes as he started to relax and lean into the pleasure.

“You want to do more than lick?” Anda offered.

“Umm… bit pinned here.” Zach managed through his gasps.

Mustang grunted and lifted Zach with his dick and thighs, his medial ring slipping inside and leaving Zach’s eyes bulging in pure sensation. Anda helped aim Zach’s achingly hard dick into her, as Mustang thrust him home, enveloping him in sopping wet warmth. He kept thrusting, shoving his forearm thick dick further and further into Zach, each slap pushing Zach into Anda. She gripped him tightly, resisting him pulling back, letting him slip deeper, her well trained muscles expertly stimulating him.

Under the combined assault, it wasn’t long before Zach felt a familiar pressure and knew he was gound to erupt. He tried to tell them but Anda pulled him against her chest, her nipple in his mouth, dripping sweet creamy milk. He sucked, panting around it, as he got pounded, and tried not to bite down as he unloaded inside her.

It felt like it went on forever, spurt after spurt filling Anda, until Mustang grunted and pushed in deeper, pressing through some internal barrier that left Zach seeing stars. He bit down on Zach’s neck and unloaded for real. A torrent of cum filled his stomach, the warmth leaving a burning trail through his belly that he could have traced. It just kept going, and Zach could feel the pressure, a mixture of pleasure, pain, and just intense senstation that left him gasping and moaning. They slowly stopped thrusting, room just filled with the sound of panting and the slow drip of fluid.

“Fuck… you two are intense.” Zach managed, feeling the burning in his ass, his stomach, his muscles, and his jaw. “I can’t believe that’s over.” His dick felt soft, his balls spent.

Anda didn’t respond, drinking whatever was in the shakes that she’d put on the table, her nipples still dripping milk. Mustang was still almost painfully hard inside of him, gently loosening his jaw and licking the bite mark.

“Sorry about that. Reflex.” He murmured, seeming a bit embarrassed.

“Is that the Bite?” Zach asked.

“Technically? But you’re already infected like 7 different ways. The more virus, though, the faster the process.”

“Oh… umm… I guess I should… get some sleep? You two can keep going.”

“You don’t want more exposure?” Mustang asked, his dick twitching and forcing another drop of cloudy jizz out of Zach’s cock.

“Isn’t that a bad idea? And it’s not like I’m still horny… I’m totally soft now. I couldn’t do that even if I tried.”

Mustang pulled back, forcing Zach with him. Zach blinked when his dick didn’t slip out of Anda’s pussy, and looked down. It had to be at least 6 inches between their groins, and his head wasn’t even showing. And had he always been that thick? No, obviously not, and a rush of pride in his new virility sent a blast of endorphins that made him want to show it off.

He felt the familiar rush of blood and it seemed not to stop, as new veins throbbed in his abdomen, pumping a huge flow to his darkening cock, his balls swelling, as a flood of hormones announced that he was very very horny.

“Oh, I think you’ll be able to keep up with us. If only just.” Mustang murmured, starting to thrust again, pure pleasure radiating from the entirety of his ass, leaving Zach gasping with each thrust. He could still feel his prostate as a hot spot of pleasure, but… fuck, his entire rectum was reporting in how much it loved a thick hard dick stretching it in all directions. His dick hardened completely, throbbing, dripping, as he started thrusting with Zach.

He started drinking again, head swimming in need and lust, pinned between his two larger lovers and loving every moment of it.

***

They didn’t spend the entire night having sex. Zach was ravenous, and even Anda’s milk could run out. “Fuck… food…” He managed, after cumming yet again, everyone dripping with sweat and jizz.

“Yeah… I could go with some too.” Mustang admitted, pulling back. Zach gasped as the medial ring crushed his prostate on the way out, the towel they’d put on the couch futile against the river of fluid coming out of his hole. Mustang admired the gape he’d given Zach while Zach shivered as a gust of cold air reached way too far inside of him. He groaned and pulled out of Anda, and then tried again as his newly black and pink dick remained inside her folds. He finally pulled out completely, revealing a nearly foot long shaft with the beginnings of a medial ring, bobbing happily above his belly button, dripping from a very wide urethra.

“… that’s new.” He said, slowly getting to his feet. His ankles felt… different now, forcing him to walk on the balls of his feet, and he was sure that he hadn’t been that defined a few hours ago. A new network of veins radiated across his body, feeding growing muscles and a layer of fuzz. His balls swung heavily between his thighs, a constant weight and pull that sent sparks up his spine, and he swore he could feel something above his ass twitch.

He managed to get over to the table, and eagerly dove into a pile of simple grains and protein, his body begging for anything that could feed it. A few bites in and his jaw clicked, shifting as it became bigger to allow him to eat more, his throat swelling with the first oversized bite of food. The other two joined him at the table. Mustang had shifted more towards equine, his dick even bigger, his muscles more defined, his nose twitching as he took in Zach’s changing pheromones, eagerly signaling how horny the new stallion was.

Anda joined in the food, playing with her chest and letting herself drip into a bucket. She couldn’t wait until she could be properly double penetrated. Her dildo collection was pretty decent, but there was nothing like multiple jizzing dicks thrusting into her all night, and her swollen mons was already complaining that it wanted to be stretched again.

After finishing his bowl, Zach managed to ask, “So… we’re just doing this for the rest of the night?”

“We might pass out around 4 am. Based on how this usually goes.”

“And then what?”

“We’re going to do some training tomorrow. You’re going to love learning how to track us down.”

“That… seems abrupt.”

“What? Following my needy scent trail, knowing the faster you go, the faster you get to claim me? You don’t want to show off how strong and dominant you are as a stallion?” Anda asked, her husky voice reaching deep into his core and twisting something, as a wet slap emanated underneath the table.

He gulped, suddenly horny again, nostrils wide and flaring, his mouth and nose pushing out into a short muzzle, flooding his brain with the knowledge of how horny she was, how turned on Mustang was, and how they’d accepted him into their little herd. Another plate appeared in front of him, and he reflexively started eating again, feeling his muscles swelling and building into the stud they wanted, as his balls churned and made more sperm, eager to deposit his load. Mustang’s dick rose in response, dripping onto his chest as he licked himself, savoring the flavor as his head filled with their combined scents and Anda’s tail spread her need around the tend.

From outside, he could hear the sound of a pack of wolves engaged in the same ritual they were, the slap of eager thrusting replaced by the happy groan of a knot being rammed home and the howl of a changing lupine.

Zach adjusted his backpack again, everything just… feeling off. Part of it was that all his gear was built for someone 6 inches shorter. His rucksack didn’t fit on his hips, it rubbed against his shoulders and back. His clothes had ripped when he tried to pull it on; his newly vascular arms, shoulders, and chest, easily straining, then ripping, the thin cotton. His new fur and hide were… able to deal with the rubbing, as far as he could tell, but it wasn’t comfortable. His ass and legs weren’t any better. Hell, they were even bigger relatively, easily carrying his weight. He felt light, even as his hooves sank half an inch into the soil. That was another thing. Epoxy bonded horseshoes, since Anda and Mustang thought they’d grow another half again. Some equines preferred tacking their shoes, but it really sucked for shifting. Mustang was pretty sure that they had a hoof kink and liked clomping around in civvies.

It wasn’t even the over-packed jockstrap that was trying and failing to hold everything in place. Mustang’s sheath kept his firehose under control when running, and it was overburdened enough that, when he clenched his abs, a few inches slid out. Zach was dealing with a nearly knee length shaft and grapefruit sized balls. He’d already kneed his himself twice when going to breakfast and his dick was still a bit angry from when it had bounced into a steel counter. People staring at it, hot. It getting in the way of walking, less hot. Ok sort of hot. Mustang had helped with some advice.

When they’d just woken up, he’d shown Zach he could push his balls between his thighs, and hold them near his ass as he walked. There was a constant tug that milked pre out of his semihard shaft, but at least kneeing his own nads wasn’t a problem. After their shower, and eager blowjobs and handjobs all around, Zach had gotten a heavy metal cockring that lifted everything up and forward. It definitely made his package even more overt, but it also gave just enough clearance to walk mostly normally. Trying to stuff his shaft down a pants leg really didn’t work. Aside from denim or nomex being stupidly rough on the sensitive skin, a knee length shaft really meant that any stimulation stopped the knee from working. You just started waddling like you were trying to hold in a massive crap.

Custom clothes to lift and separate was really all that you could do with equines, but that meant you needed to be fully shifted to actually get measured. That was a few days down the road, and even then, it was possible to get hit with a late growth spurt depending on hormones, sex, exercise, and nutrition. Modular clothes were more feasible, but… that was definitely a tomorrow thing at the very least. His thighs were still dwarfed by Mustang and Anda, and they couldn’t wait until he could lift them off the ground.

Hence… he was wearing epoxy horseshoes and a jockstrap trying to contain a coiled python and two small melons. Hot… not quite practical. The backpack at least felt pretty light, even with the gallons of water he’d need.

The eagerly sniffing new lupine he’d been battle buddies with wasn’t exactly helping things. He felt a cold nose on his ass and stiffened. “… Please…” Zach said a tad helplessly, not sure what exactly he was complaining about, his jockstrap straining at the proximity of a panting eager mouth.

“Oh sorry…. Umm… you smell nice. And erm… horny.” The lupine said, tail wagging, ears high and alert, a bit embarrassed but not much. They’d sat together yesterday, and they were paired up today. If their last names weren’t so close together, Zach would have suspected something.

As it was, he was a bit more suspicious of the lupine’s nose, which kept drifting nearer. “So… I’m Zach.”

“Rover!” He barked happily, then cringed a bit. “Sorry, umm… alright, let’s start planning out the route.”

Zach blinked. “There is no way that your name is Rover.”

“Most people choose a new name to go with their new identity. I’m Rover until I can prove myself to the rest of the pack.” Rover said, a bit quietly. “Does the mental image of Zach fit with a seven foot tall, bronzed, mohawked stallion with a fuckhammer longer than my forearm?”

Zach blinked a few times, trying not to let said tool harden. “Please never refer to any part of my body as a fuckhammer.” He finally managed.

“Come on, that thing is a lethal weapon intended to pound. It’s a fuckhammer.” Rover said, glancing towards the straining pouch.

“Dude! I’m bi, but that’s going a bit far. We just met.”

Rover looked a bit embarassed and nodded. “Sorry.”

“No problem. Just… let’s try to get to know each other a bit better before saying stuff like that. Keep it vaguely professional.”

The others left them in the training area and drove off. They had a map, a compass, enough food and water for 8 hours, and a destination. Rover pulled out a map pen, and started finding the destination. “Alright… looks like it’s on the shore of this lake here. Near these hills… shouldn’t be too hard to find… just need to go around the lake and get to the eastern side of the river… the question is where are we now…” Zach looked at the map. Couple dozen square miles of ranges, trails, firebreaks, and mostly natural land. This part of the training area had a 4 lane highway cutting it off to the north, and another to the east. To the south was the main camp, and the west was mountains.

The area around them was a forested grove, with a gravel road leading through it. Off to the left was a gully turning into a swamp. Off to the right was a clearing that led towards a ridge-line. They’d been kicked out of the vehicle without any guidance, just told to figure out how to get to the bonfire and to trigger the emergency beeper if they gave up.

“So… we’re looking for a flat piece of land with an improved road next to a circular depression with a swamp at the bottom and a ridge-line…” Zach said. Rover looked around.

“Oh…. That makes sense. Do you think this is a campsite? Smells smokey.” He asked, sniffing the air.

“I… don’t think so. Look at the underbrush. It’s pretty much gone. I think they burnt back this area recently…” Zach said, walking over to the trees at the side of the road and inspecting them. There were clear scorch marks on the trees and ashes accumulated into piles from recent rain.

“Well… that eliminates this road…” Rover said, tracing a camping area open to the public. “Umm… there’s a lot of roads to check.”

“Well… not… too many… we’re mostly looking for roads near streams… and we mostly need to figure out if we’re going to head the wrong direction towards the meetup…” Zach said, and looked at the map one more time, before getting up and walking off.

“Hey! Where are you going?”

“The meetup point is in the upper left of the map. So… unless they’re dicks, which is always possible, we should be pretty good. We just need to not cross any highways. Or climb a mountain.”

“Oh… yeah that makes sense.” He got up and eagerly followed.

A few hours of hiking later, and Zach decided to take a quick rest against a tree. He was covered in small scratches, somehow soaked in dew, and hungry. Rover walked up and sat next to him, panting happily.

Zach glared at him for half a second and rummaged inside of his bag for a ration pack.

“What’s up?” Rover asked.

“Nothing. Just… fucking hate nature.”

“Oh, it’s not that bad.” Rover said, looking around. It wasn’t objectively a bad day. Not too humid, not too hot, not too sunny, but Zach was annoyed that he was out in it at all. Rover constantly running around and sniffing things was just irritating, even if he couldn’t really articulate why.

He angrily bit into something cheesy in a pastry wrapping. His feet were sore, his muscles were complaining, his balls were aching, and his dick wouldn’t stop begging for his attention. It started hardening, stretching the jockstrap until he finally relented and allowed it out. It lay over his thigh and onto the ground, then he felt the familiar rush of blood and it started lifting itself, eager to play.

Rover’s tail was wagging, and he sniffed again, glancing back at Zach. “Oh… umm… you doing ok.”

Zach blushed, eating a pastry, his dick dripping on his chest, angry, mortified, horny, and sore in equal measures. “I can’t fucking tell.” He managed after a few second’s reflection.

“Are you feeling… like everything at once?”

“Umm… a bit?” Zach confessed, trying to ignore the throbbing two feet of stallionmeat in his face, flooding his head with pheromones, his balls aching.

“Yeah, you’re getting hit by a lot of new hormones as your brain gets rewired to deal with a new limb and a lot of new instincts. Jizzing helps.” Rover said, standing up and walking over, his dick sliding out of his jockstrap. It wasn’t as… overwhelmingly massive as Zach’s horsecock, but it was a hefty thick-

Zach shook his head, mouth suddenly watering for something new.

“Umm… alright then…” Zach said, catching some of his dripping slippery pre, and touching his dick. He gasped, as the extremely sensitive flesh practically sparked, eager for more stimulation, surging fully, his balls suddenly feeling crushed in the jockstrap, his ass needing to be filled with something. He pulled down his jockstrap, blanketing the entire clearing in his musk as one hand started running up and down his shaft.

It was too thick for him to wrap one hand around and the other one was eagerly invading his slick asshole, pushing past his winking doughnut. He shuddered and coated his face as he pressed against his prostate, milking nearly half a cup of pre just by being touched.

“You need a hand?” Rover offered, his own jockstrap off to the side, his gear on the needle covered ground. He was slowly pumping his three hand long shaft, paying attention to the couple fingers of bulge near the base. He was hot, Zach admitted to himself, his abs and pecs stark, messy hair cute, muscled build vascular and dominant as he stood over the needy stallion.

“Yeah!” Zach said, lifting his rear off the ground with his two hooved feet and pulling his balls out of the way of his thick doughnut. Rover’s eyes went wide.

“I… umm… ok, yeah. I can do that.” He stammered, half making a wanking gesture, as he approached Zach. He knelt down and hesitantly licked the equine’s shaft, milking a happy squeak out of Zach, as he lifted the stallion onto his thighs, thick pointed shaft pressing against the offered hole.

“You ok with this?” Rover asked, a tad concerned at how quickly Zach had become a begging slut. Zach nodded eagerly, dick throbbing as it bounced off Rover’s abs and pecs. He lowered himself, feeling the pointed head easily slip inside, then gasping as it pushed against his prostate, sending a happy lightning bolt up his spine.

Rover bit his lip, trying not to thrust until Zach was ready, as Zach kept lowering himself, dick coating the two of them in salty pre. “God, you’re fucking - ugh - thick…” Zach managed, needing to pause, as his asshole spasmed around the lupine. He sat there gasping, as his doughnut slowly relaxed, and winced as the shaft reached the turn in his rectum. He knew that Mustang had gone much deeper but… he wiggled around, trying to figure out what had happened last night, when he felt the throbbing hard shaft press against another spark of sensation and reflexively dropped down another few inches.

The clearing echoed with the sound of his scream of pleasure as his dick sprayed the two of them with cum, Rover’s proto-knot crushing his prostate at the same time his rectum shifted to allow him even deeper, a new organ eagerly demonstrating how sensitive it was.

Rover gasped, reflexively starting to buck, as his entire dick was enveloped, Zach’s asshole eager for sensation, blinking cum out of his eyes as Zach’s dick kept oozing cloudy fluid, his balls still clearly full from how Zach was thrusting and stroking. The equine was collapsed against the lupine, his shaft between the two of them, as they started to thrust again, slowly picking up speed as they got nice and nasty together.

***

Finally, Zach felt satiated, his ass filled with wolf jizz, his balls drained, and he collapsed against Rover, pushing his dick out of the way, nuzzling against the matted lupine.

“Thanks…” He said, kissing Rover’s cheek. His eyes surged open. “Umm sorry… didn’t ask about kissing.”

Rover was drained, legs weak, head swimming in the stallion’s musk. He laughed and kissed back. “No problem. No homo, balls didn’t touch.”

Zach’s balls were separated from Rover’s by a thick sheath and shaft, so that was technically correct. “So… how long were we going at it…?” Rover trailed off.

“Looks like a couple hours?” Zach said, looking at the sun, slowly moving towards noon. “Umm… I do feel better.” He said happily, lifting himself up off the shaft as a torrent of cum poured out of his ass and onto the ground.

Rover shakily stood up, and looked down at himself. “Woah…” he murmured, cupping the thick knot that was keeping his dick happily dripping away from his body. “Guess… that was a lot of hormones. Fuck, I’m starving.”

Zach laughed. “Yeah… same.” He grabbed their packs where they’d been dropped and pulled them over to the tree, as the two leaned against each other, opening some rations. They ate in silence, mostly aimed at getting calories into their demanding bodies.

“Wow… I acted like a slut there.” Zach said eventually, reflecting on it, head still sparking with endorphins.

“Yeah, it was fucking hot.” Rover murmured back, his dick twitching at the memory. He was sore, a bit scratched up, maybe a bite or two from the eager stallion, but was feeling pretty fucking great. “I’m just glad that you’re a bottom, that thing would have killed me.” He gestured towards the forearm and fist length shaft still drooling onto the ground, joining the general lake of fluids they’d made.

“… I guess I am a bit of a bottom. Never really thought about it that way before.” Zach blushed, finishing one rations pack and starting another.

“You took me like a pro.”

“Well… Mustang really opened me up last night. And that was… an experience. Dude really knows how to make someone feel special. I thought he was just using his dick as a battering ram but… he just slid in. No real pain… somehow.”

“Did I hurt you?” Rover asked, concerned.

“Not really… just took me some effort to adjust…. You were great.”

“That’s pretty good though. The other people in my pack were joking about how they’d need to open you up for Mustang and Anda. Something about pack animals needing to stick together. Then I sort of lost track after two of them knotted me at the same time and I swallowed another shaft.”

“Huh, I mostly got pinned between the two of them…” Zach’s shaft lifted itself off the ground at the memory, apparently ready to go another round. “Oh come on…” He groaned at his libido.

Rover laughed again. “You’re a stallion mate. Your body expects to satisfy 5 or more oversexed mares, and maybe a powerbottom or two. Once the Bite fully hits, you’ll be able to run for days, and fuck your way through most of the camp.”

“… suddenly I wish I had spent a bit more time watching equine porn. Just seemed… too unbelievable.”

“Oh, a lot of it is exaggerated, or even outright lies, but there’s some truth to it.” Rover said, staring at the massive shifting head and splotched shaft. His balls were clearly larger and the sack more leathery, able to hold them in place better, the beginnings of a sheath forming, as his mane grew out. “Like, your cum doesn’t produce chemical dependency, and your musk doesn’t brainwash people into sluts, but I definitely like pretending it does.” He nuzzled into the stallion, inhaling deeply, feeling their mostly matted fur rub together.

“We… can still have sex with normal humans?”

“Oh yeah. I mean… there’s some people who think it’s perverted, but the risk of spread is pretty limited without the shot regiment we got. Plus people who are interested can get some inoculations against the effects for added protection.” Rover said.

“Were you one of those people?” Zach asked.

“… no. I wanted to be.” He admitted.

“Perv.”

“Hey! They’re hot! Erm, we’re hot!”

“So… are we like gay now or something? I definitely wasn’t this down for random sex before…”

“I think that’s an open question? I’ve seen arguments that it’s just a supercharged libido making people more open to sex from either gender, the environment making people more willing to explore, new nerve endings changing associations… it’s really a topic of active study.”

“And your interest was…?”

Rover blushed and ate more of his rations.

Zach leaned over and kissed him, leaving a tomato sauce mark on his cheek. “You’re cute.”

“I am not cute! I am a wolf! I can tear someone’s throat out with a flick of my neck!”

“Yeah, but you’d rather choke on this anaconda than do that.” Zach waved his shaft back and forth. Rover’s eyes tracked it, forgetting to eat for a few seconds. “Heh, perv.”

“Fuck you.” Rover said, relaxing onto his back, dick dripping, early afternoon sun shining on them.

After a bit longer, they finished their meals, and stood up, heading towards the northwest again. It was hard for Zach not to notice Rover’s eyes on him. “So… did you want to be an equine?” He asked, checking the map and seeing if he could place them.

“Eh… no.” Rover said.

“Why? You seem… interested?”

“Because… well… it kinda sucks. It takes a lot of internal changes to take that monster.” He said, gesturing to the snake happily laying on the ground, still dripping pre.

“… as in? I… feel pretty great.”

“It kinda fucks up your digestive tract, hard to keep everything flowing smoothly when you also need to be able to take 2 feet without ripping everything apart. You might need to go on a specialized diet.”

“… that seems pretty minor?”

“Eh… a lot of it is more the social connotations? The people who choose to go for equine variant infections tend to be small dicked egomaniacs? Since it is based on actual equine DNA, the intended population ratio is 5 ish women to one man, and that curve is completely blown. And you’re not fitting in anyone except for the kinkiest furries and other equines. Lupines and Canines are… reasonable-ish. Like, I’m going to max out at around 10 inches. Big, but… partners can work on stretching together. And I am mostly a bottom. Most equines very much aren’t.”

“So… Mustang and Anda…?”

“Were dating before they joined and are massive perverts, based on what the pack said last night while you were moaning like a bitch. They also are fine with switching. The single soldier barracks for equines is… a bit unhealthy. Lots of built up resentment.”

“Huh…” Zach said, looking at his length speculatively, not entirely sure how to feel.

“Surprised you didn’t know about it.”

“I… didn’t know much about equines other than what was in porn.”

“And that’s an entire other nightmare. The joke is that any equine can get into porn if they can’t get a job anywhere else. And that’s true, but it becomes this whole hostile culture of amateur porn stars and trying to build a following. Just having a big dick doesn’t mean that much if you can get one by sucking off another equine. Or buy some goo off a shady website.”

“Is this like your hobby? The hidden life of mutated porn stars?”

“Eh… it rubs off if you get into the culture enough. And enough people think they can get in on it. It’s like someone who’s into doing tattoos but has no… real experience or training. Past a certain point, there’s morbid curiosity.”

“Like what?”

“Well, the whole ‘free six pack abs’ thing. Your body burns a stupid amount, but it is stupidly optimized for running. If you don’t stay on your feet, equine hooves will start to break down. Someone trying to jump on the ‘easy path to fitness’ with the Bite really gets hit hard by reality when their entire diet shifts out of necessity and their home needs a lot of adjustments to cope with the changes. Or they don’t and they get hit hard by the health effects. Six pack abs mean extremely low body fat, and that means extremely careful regulation between how much you can exercise, how much your body wants to exercise, and what you’re able to eat. It’s like people who take steroids and don’t train right. Muscle tears, undesired weight gain, and emotional problems are just the start.”

“Uhhh…” Zach began, looking at the packs of food he’d been eating.

“Yeah, you’ll be chatting with the company nutritionist and personal trainers later this week. It takes a lot of upkeep to stop equines from falling apart. Ask any horse girl.”

“Speaking of which…?”

“Yeah, it’s a common porn scenario but… mate, there are very few equine ‘stallions’ who want to be submissive to a rich uptight girl that wants to control everything about their lives. And the ones that do are basing their relationship on being effectively kept. That’s fine for a decade, but after that, try explaining the gap in your resume.”

“… this seems more complex than I first anticipated.”

“Dude, it’s life. You have a big dick and perfect muscles now. And society is going to punch you for every advantage it offered.”

“That’s a tad hostile.”

“Sorry, meant it to be a bit more joking. But you didn’t know any of this?”

“Not really. I mostly signed up because I wanted to work with radios and I liked camping.”

“What? Seriously?”

“Yeah, I was the head of the HAM radio club in high school and I didn’t really have much else in my hometown to keep me around after school. I knew the Bite was a possibility, but I didn’t expect to go to a front line unit. Thought I would be maintaining satellite dishes and setting up networks. I wasn’t like… totally freaking out about joining the cavalry, but...” Zach shrugged.

“… your recruiter is a dickhead.”

“Hey, I like dickheads. They’re fun to suck.” Zach quipped.

They both chuckled.

“Well, let’s get going. Should only be a few more hours, and I suspect that we’re going to have a fun time tonight.”

***

They continued on their way, finally confident of where they were on the map thanks to a useful intersection between a couple roads and river. It was a pretty easy path, and the two enjoyed the ongoing chat. Definitely more dick heavy than Zach was used to. Rover was a bisexual dog with a mission, and that mission was knots and boners.

The lake came into view as the two crested a hill. Looked like it was used for helicopters, given the clearing that had been cut and the markers. They could see smoke from a campfire next to a waterfall. “Huh… guess we were a bit off on that.” Rover said. “Thought it was a river.”

“A waterfall is a river, just a fast one.” Zach disagreed, adjusting his pack, his stomach already starting to want more food.

“… I… that feels wrong.” Rover said.

Zach and Rover kept traveling, arguing over exactly what qualified as a river. “Oh come on, by that standard, a waterslide is a river.” was the final comment as they reached the lake’s shore.

“So… do we swim or walk all the way around?” Rover asked.

“… I do not trust myself to swim that far with these hooves.” Zach said.

The two walked around the lake, the sounds and smell of a proper Roman-esque orgy ongoing. “Hamburgers?” Rover asked, sniffing the air.

“I’m getting hot dogs.” Zach said, running a hand down Rover’s back, leaving him shivering.

“Why did that feel so good?” He asked out loud, as they approached the campsite.

“There they are!” A fully equine, 8 foot tall Anda called out, waving a bottle, knotted by two happy lupines. “Nice timing, grab a plate, a drink, and let’s get enough food in you to make you a hunky stallion.”

The lupines howled happily as they saw Rover, thick shafts and dripping slits everywhere. Mustang was full equine, having fun with a couple lupines, eating one out as they ground against his shaft. The musk hit Zach like a freight train, and his jock strap gave up the fight, ripping off as his shaft slapped against his chest a few moments later. “Good boy.” Anda said, and Zach shook at the simple complement.

He tried to hide it, and grabbed food, eating mechanically as flashing fangs and boobs left a lot of confused happy signals jumping across his brain, completely overwhelmed.

Rover was pinned between two lupines, eagerly knotted front and back, starting a happy howling train.

Anda was a bit tied up and loving it.

Fully Equine Mustang sat down next to Zach, his hooves sinking into the sand, as his stallionhood lay across his thigh and onto the ground. “How are you doing? Everything ok?”

Zach jumped, and swallowed, trying to finish the meal. “Umm, yeah! Doing great! Just hungry.”

Mustang smiled, relaxed. “Good job finding us. You wouldn’t believe the number of people who get too distracted or lost.”

That same shiver from the complement. Zach dug his hoof into the sand. “Maybe a bit… overwhelmed. What’s going on? Like, orgy seems fun but… is there anything else going on?”

“So… basically for a proper shift, you need to actually train muscles. 10 miles of walking is a pretty good way to do that. Plus you should get to meet other people. If you two can’t make it here because someone is a dickhead, we really don’t want you to be part of the herd.” Mustang said.

“And I passed the test?”

“Pretty much. Being willing to blow off steam with other people, intelligent enough to actually navigate here, and aware enough to eat and drink on the way… it’s a simple test to see if you’re vaguely competent. And I’m down for helping you build towards the rest.” Mustang said, handing Zach more food.

The two munched in silence, as the screams and howls of an eager orgy continued around them.

“Is there a reason why you’re not joining in?” Zach asked after a bit.

Mustang shrugged. “Eh, we have the rest of the night, and you seemed a bit… contemplative. Not going to push, but I’m here if you want to talk.”

“Just… we had a chat about equines. And like the problems they have.”

“We have.” Mustang gently corrected.

“Yeah, that. Umm… so… what’s going on there?”

“While you’re here? As long as you’re not a douchebag, you’re welcome to join our bed. You’re cute, and we looked at your personnel file. You haven’t changed your name to Studmeister, you did well in the trainings, you’re open to topping and bottoming, and you’re not using this to hide from other problems. So far, I’m happy with the choices you’ve made.” Mustang pulled Zach close, into a gently kiss, both of their shafts hardening. Zach tasted booze, milk, and honey on his tongue as the two of them toyed with each other.

They broke apart, Zach gasping. He put his plate to the side, and swung a leg over Mustang’s hips.

“If I had changed my name to something like Mustang?” Zach asked.

“Then I’d be a bit more worried. But it’s not a deal breaker. I got the nickname because I arrived in my uncle’s old car, which happened to be a Mustang.” Mustang said, muzzle wrapping around Zach’s achingly hard shaft, easily swallowing down the fist thick shaft.

Zach gasped, his ass feeling empty, as Mustang’s shaft pushed against his upper back, forcing him forward. He hugged the larger male, shaking, as a large figure approached from behind.

“May I join in?” Zach nodded. “Your ass open?” Zach nodded, more eagerly, and he gasped as his doughnut was parted by a thin point, rapidly thickening until Zach was enveloped by hard muscle under matted fur. The lupine lifted Zach up, as Mustang lay back, thrusting his shaft between his pecs, hands running up and down the dark wet pillar.

Zach felt his hole stretching, and he winced as it started pushing beyond what he could take. With a happy gasp, he slid down a few inches and his doughnut wrapped around a fist sized knot, as the wolf started to bounce him, easily holding the equine in the air, one arm under his knees and one around his waist. “You feel great.” The wolf murmured. “Good job taking me.” Zach blushed hard. “I think your new herd-member has a bit of a praise kink.” The lupine said to Mustang.

“Oh I know. And I want to see how well he can treat me.” Mustang said, rolling back and exposing his prepared hole. “You ready to show me what you can do?”

Zach nodded eagerly, gasping as the knot rubbed against his prostate, dick throbbing and dripping. The lupine slowly lowered the two of them to the ground, and Zach saw stars as Mustang gently guided his shaft to meet with his doughnut.

Pushing forward, Zach slipped into Mustang, the skilled hole easily taking his length as the sudden intrusion milked a spurt of cloudy fluid onto Mustang’s chest and neck. “Good boy.” Zach clamped down on the lupine behind him, as he pushed forward, trying to please Mustang, shuddering as more and more of his shaft was surrounded by velvety warmth, pushing deeper and deeper.

It wasn’t that long until Zach was fully in, and he started trying to thrust. Mustang knew how to treat a stud, tightening with each pull out, holding onto him and milking his shaft, thrusting back as he kept playing with him self, his hard shaft pinned between their chests.

Mustang pulled him into another kiss, as the lupine started thrusting, gradually loosening up Zach’s doughnut, each thrust sending sparks up Zach’s spine as his prostate was happily pummeled, thrusting him deeper and harder into Mustang.

Mustang’s taste on his tongue, his scent filling his head, his dick expertly milked, and his ass being pummeled, it didn’t take long before he felt the familiar pressure filling his prostate and he gasped around Mustang’s tongue as his ass clamped down on the lupine’s knot, and his balls unloaded.

The lupine didn’t give him any time to recover, and a few thrusts later, Zach realized he didn’t need any. His balls and dick could keep going, even as he sprayed inside the larger equine with each pulse from his abused prostate.

A few thrusts later, the lupine behind him bit into his hide, as his knot inflated, crushing his prostate again, and milking a few more spurts, as warmth filled his belly again. All three of them took a few seconds to catch their breath, then eagerly kissed and resumed their thrusting, the assault just beginning.

Zach woke to the feel of a wet kiss on his lips. He kissed back and smiled, opening his eyes to the early dawn. A flat blunt head stared back at him, hard, leaky, and happy. He closed his eyes, sighing internally, and then gave himself a long lick. He tasted salty, with afterhints of hamburger and wolf. Zach uncurled, and slowly got up. He stretched, then carefully stepped out of the orgy, trying to avoid a couple knots of snuggled up lupines. His dick was keeping him very aware of the muscular naked forms, telling him how nice it would be to join and continue snuggling, sleeping, and thrusting tin the predawn air. A few of them were awake and making out gently, trying to not awaken everyone else.

“You’re going to get me in trouble.” He said, sternly to the spire between his legs. It leaked happily, begging for him to play with it.

Groaning, feeling his legs thrumming and begging for use, he made it out the door flap, eyes quickly adjusting to the slightly more light. Outside of the communal tent, he found Mustang and Anda gently talking to each other, holding hands and looking up at the stars.

“So… is this normal? Not being able to sleep for more than 4 hours at a time?” Zach asked, rubbing a sore shoulder. He had been locked between a pair of thighs for a pretty long time last night and whoever was behind him had not exactly cared about the amount of pressure they had put on the equine.

“A bit. Come on, sit down, enjoy the dawn.”

“This is dawn?” Zach asked, looking into the darkness.

“You’re able to see? It’s dawn.” Mustang said.

“Before morning nautical twilight began 20 minutes ago. You’re seeing the sun starting to wash out the Milky Way.” Anda said, pointing towards… something. Zach had no idea what.

“If you say so.”

“Oh shut up and cuddle between us.” Mustang said,

Zach slid between the two, enjoying their warmth. He was definitely taller, thicker, closer to their forms, and he adjusted himself so he didn’t rest against Mustang’s mostly soft maleness.

The three sat in silence for a few minutes, until Zach’s nose filled with the scent of need. “… ok, which of you is horny?” He asked.

The two laughed. “All of us, I think.” Anda said, her nose flaring.

“Sounds about right. You want to go for a run? Whoever catches each other wins.” Mustang offered.

“What do we win?” Zach asked.

“Oh, Zach, that indicates a certain lack of… creativity.” Anda purred. She stood up and stretched, her back cracking, her taut, capable, strong form instantly triggering a rush of blood.

“Don’t let that go too far. She’s not going to let you chase her.” Mustang warned, standing up, and loosening up. Zach stared open mouthed at the couple, clearly comfortable and eager and…

He realized exactly how eagerly and… almost predatorily they were staring at him. His heart started to pound, his shaft softened, and he suddenly started needing to run.

“Yellow. You ok with this?” Mustang asked.

“Umm… you two chasing me and pinning me down and making me jizz my brain out?” Zach asked.

“Something like that.” Anda said easily.

“… yeah, that’s hot. Really into it.”

“Green. Start running, mare.” Anda said. Mustang lunged for him and Zach recoiled away, getting to his feet and beginning to run along the lake’s edge. The other two followed him, easily keeping pace, herding him forward.

“Ok, this isn’t fair, I don’t have a herd to hide in.” Zach gasped, as the ground started to become more swampy, and he was forced to turn off, heading into the forest, towards dryer land.

The other two didn’t answer, other than to spread out naturally, cutting off any other direction for him to move. Zach kept running, his tail lashing. I have a tail? Neat! I have a tail. It kept balance twisting and whipping back and forth as he kept going, helping maintain his center of gravity as the he started to head uphill,

He kept running, his heart pounding, as his body began to sing, loving running for its own sake, the fact that there were two sexy studs- yeah, the word applied- chasing him not really changing the feel as the miles started to disappear under his hooves. He broke out of the forest, sweat dripping down his body, dust caking his ankles, as an open plain spread before him, amber stalks drifting in the wind, the sun starting to peak out over the horizon. He stood there for a moment, mouth open at the majesty of the world, when a 2 ton mare tackled him to the ground.

“Wha-?” He managed, before rolling across the dirt and plants, pulled tightly against a a strong dominant woman, joined moments later by her husband as he dived into the pile.

“You’re adorable, pausing to contemplate the good life while being chased by two calvarypeople.” One of them murmured into his ear, as the other slowly started to play with his prostate, his body involuntarily reacting.

“I guess I lost?’ He asked.

“I don’t know, I think you won.” Anda purred. “Not many get stuck between two ripped equines to enjoy the sunrise.”

“Am I going to enjoy it, or you two?” Zach asked.

A thick intruder and a nibbling at his neck helped answer the question.

Anda was naked aside from a utility belt. It contained all the necessaries for her games. A locator, lube, a 24 inch strap on, a pair of handcuffs. And she grinned as she pulled the one into place.

“You’re definitely welcome to enjoy all of this. But not many people have managed to compose poetry about the sun while I’m pegging them silly”

“I’ve managed dirty limericks before.” Mustang said, starting to thrust.

“Like what?”

“There once was a horse from Montana

Whos lover was simply inspira

With a lick and a grin

she cleaned sperm off her chin

Abs taught and breasts beyond imagina”

Zach’s head was blank, cloudy fluid dripping from him with each movement. He nickered happily, rubbing his head against their necks.

“I think you might have broken him.”

Mustang seemed honestly put out that Zach hadn’t heard his limerick. “Awww….”

“Don’t worry, he’s going on the nutrient drip for the rest of the shift in a few hours. You can recite all the poetry you want then.”

Mustang laughed and kissed Anda. “You always know just what to say to perk me up.”

“Usually I don’t need to say much at all. I just need to look at that amazing body and those foal makers between your thighs.”

“And I just need to smell a hint of you or get a glance of that amazing form. I wash I could draw better, you deserve to be featured in galleries.”

“I don’t know about your understanding of fine art, you’re trying to seduce me while we’re having sex with a pheromone drunk stallion.”

Said stallion was definitely more than a tad out of it, rubbing aggressively against Mustang’ neck, hands on Anda’s hips, as he thrust back against their invading shafts. He yelped, and went rigid, unloading over Anda’s abs and chest.

“Aww, that’s always so much more fun inside.”

“Don’t worry, we have plenty of time later today.”

“Oh, I am going to hold you to it. My legs barely feel sore.”

“I’ll do my best to leave you recovering in bed all tomorrow.”

“Aww, I knew I married you for a reason.”

“And I didn’t even need to be an 8 foot tall hung stallion.”

“Not in the slightest. But it definitely made things more fun.”

A nearby group of cats, training in infiltration, couldn’t tell if they should feel disgusted, horny, or jealous. A number of undergarments did need to be thrown into the laundry that day, regardless.

***

Zach was starting to recover after his training that morning, and was still wet from the power washing that Mustang and Anda had subjected him to. He was sitting in the medical wing again, wearing loose scrubs, waiting for the medic to check him out again, trying not to enjoy how well he filled out the formerly unconstricting medical garments.

Before, it would have hung limply, now… it was taut across his shoulders, loose at the waist, stretching at his biceps and thighs, and trying to contain a python and smuggled grapefruit. His sheath was still developing, and he definitely felt the aftereffects of his balls and shaft bounding around so much during the morning run, but… well, a bit hidden under the afterglow and the painful pleasure still radiating from his ass.

“You’re looking better.” The same medic from… fuck, was it really just 2 days ago? Whatever, walked up, looking him over. “And you’re filling in well. We’re going to give you a nutrient drip and a solution of pure virus. Should help push you through this stage towards completion.”

“… Umm,.. alright ? What exactly does that mean?”

“So, right now, you can only get bigger. But that sort of sucks for actually like… dealing with day to day life. 8 foot tall ceilings means that you’re going to be stooping everywhere.”

“How does that work?”

“What part?”

“You know… shifting?”

“No idea.”

“… that’s helpful. I would have assumed it violates conservation of energy.”

“So… ok, look, there’s a number of research projects, but what I understand is that the virus forms a 5d structure within your body that leads into your vena cava, which introduces something called impressionable matter into your body. The transformation process produces a structure of existing 5d virus that enables your cells to rapidly incorporate the matter and expand, or rapidly reduce it and expel it out the other side of the 5d structure.”

“… what the hell do you mean by 5d?”

“Exactly that. It has an additional temporal dimension and an additional spacial dimension. It can concentrate energy and mass in time, and draw on it from other portions of our possibly 2 dimensional universe, depending if you think that hologram theory is accurate.”

“… what?”

“Well, in that instance, it’s possible that we actually are a 3d hologram projecting off of a 2d substrate, which has some useful implications that help explain quantum interactions-”

“What do you mean spacial and temporal dimensions? Why can a virus do that?!”

“Well, some scientists theorize that a 5 dimensional being created the various strains of the virus for some unknown reason.”

“A god created the virus. Which allows us to break the boundaries of conventional physics, because of unknown reasons… and I’m the result?”

“Well, everything here is the result, but yeah. We’ve managed to get a few probes through the portal, but they attempt to respond faster than fibre optics can transmit data, hence the temporal dimension, and also receive approximately 33% more photons than their sensors can compute, hence the additional spacial dimension. What we can receive also shows evidence of spikes in directions that would be consistent with a point data source in a 4D field.”

“… we have broken conventional physics. With a unknown being. And we immediately used it for war.”

“And sex. You wouldn’t believe the number of porn genres that have been enabled. Purrfect Play is a major motion picture coming out in the fall.”

“Something approximating a god exists. We used it for sex and war. And immediately started writing physics papers on how it enables us to explore the fundamental nature of reality, after possibly breaking the speed of light.”

“Well, we don’t think the speed of light is different, just that time is compressed. Relativity still works out. Or the probe could have shot out at some insane speed, but that would require actual creation of matter.”

“Wouldn’t that be… 6th dimensional? Since we live in a 4d world?”

“From our perspective, time is linear, so we don’t experience the world as 4d. We are just dragged along by the arrow of time. We don’t know if the structure is time independent, but it seems to be anchored in the same spacetime as us, since there’s free flow between the two positions. It does have at least 2 dimensions more across the border, but that’s just based on what we can detect. String theorists are still arguing over the number of dimensions in our existence. 5d is just our interpretation given the data we can detect. It could and likely is wildly different.”

“And… why do we think it’s a 5d being rather than… anything else? Like naturally occurring?”

“Mate, look at yourself. Abs like that from a natural virus doesn’t make sense. Humans have too much sex with anything for an STD to be concerned with being sexy. Syphilis made people’s faces rot off. And that was still not enough to halt its spread.”

“That doesn’t make any sense. Why would a 5d being introduce a sexy engineered virus to turn people into horses, wolves, cats, all the rest? Just… why?”

“Well… if we made a movie about a future frat that went to another planet and filled it with sexy furries, would you say that is entirely implausible? Or just immoral and a waste? Because I can definitely imagine some people I worked with doing that if it was feasible.”

“… ok, we have a kinky god who wants humans to turn into hung horny anthro animals and bugger each other silly?”

“No idea. That’s the fun part of science. I can speculate on the reasons, and just do studies into the results. Speaking of which, let’s get that portal totally formed.”

“But what stops me from just… keeping growing. If people can shift shift back and forth… why not just keep shifting forth?”

“Well, simple answer there. Simple-ish. You only have so much structure for the impressionable matter to fill into. After that, it completes a circuit and passes out of your body. We’re working on grafting additional virus structure to get around it, but it hasn’t worked so far. Not sure why. I personally assume it’s because too much muscle isn’t hot. Fifteen feet or fifty, you’re equally able to destroy a building.”

“… so… the best way to get bigger might be to create a town sized for my stallioned out body, and see if the 5d being is interested in building me up further so I can super-stallion out?”

“Or staying at that size for so long helps build additional structure. We have no idea. It’s hard enough feeding y’all now.”

“Doesn’t this mean we can produce a perpetual motion device? Have 2 growing machines linked in opposition?”

“Well, we haven’t figured out how to keep the portal functional in a machine yet. And, naturally, you get hungry faster than you gain mass. With an effective energy extraction of less than 5%,, any form of perpetual motion device is pretty severely constrained”

“But it is possible in principle?”

“Well, we aren’t 100% sure on the limits of the fourth and fifth dimensions of the portal, but …. maybe? You want to go for a theoretical physics doctorate or fuck some mares?”

“… and some stallions, yes.”

“There you go. The theoretical physicists and the art department would appreciate more volunteers for subjects though.”

“… the art department because?”

“Dude, people be horny. And 8 foot tall muscle bound monsters hit all the Disney prompted kinks that people have been binding up and shoving into a deep dark corner of their psyche.”

“Do you talk like this with everyone you examine?”

“Not usually. But it’s pretty easy to tell when someone is dumping pheromones and is horny as anything. Even ignoring the tent that is showing off literally everything.”

Zach lunged for his pants, a weird mixture of blushing and proud as he tried to cover himself up. The pride surged as it became evident that even his ham-like forearms weren't enough to hide it. Or the spreading dark stain on his top.

He signed and lay back, accepting the reality of the situation. A flow of cool fluid entered his body, and he relaxed as endorphins started radiating throughout.

***

Zach expected there to be more of a difference after he woke up. Though most of what he’d experienced was… aggressive enough that it didn’t change too much. If you can’t wear pants because of your grapefruit sized balls, coconuts aren’t “that” big a difference. And the massive sheath stretching from thigh to thigh wasn’t nearly as annoying as the pendulum that had swung between his knees before, even as it stretched up to his belly button. The heavy hooves meant that he did need to walk on a preset path, and he had apologized profusely when a misstep had shattered one tile, but the carefully fitted horseshoe and spreader plate beneath it was pretty useful. His muzzle, mane, overbuilt body, and thighs weren’t that outrageous either. The carefully measured clothes even made them look vaguely professional.

What was giving Zach trouble was the cloud of scents constantly demanding his attention and the stream of information that it fed to his brain. He really didn’t need to know whether someone was ovulating or not, but his balls very very much enjoyed the info, and it was everything he could do not to ruin his new clothes as his sheath demanded to release the monster hidden within.

Mustang and Anda had met him in the waiting room, cheering for his new body, and were helping him learn how to shift back down. Well… they took turns. In a sense. They were skilled enough to control their pheromone output and one was helping coach him while the other smothered him in horny need. Bastards.

Zach grunted as his break away codpiece separated from the rest of his clothes, the rain poncho like clothing releasing his balls and sheath to swing heavily in the air as Mustang’s tail lazily waved back and forth in front of his face, ass dripping lubricant, yet more evidence that whatever had created the virus was a whore.

“Bad boy.” Anda said disapprovingly. Zach blushed. He honestly wanted to make her proud and wasn’t 100% sure why, but… getting hard in front of her husband was giving him all the weird feelings.

“Is this the best way to trial it?”

“Growth is tied to sex. At least in my experience.” Mustang said, his ass swelling a few more inches, tail growing, scent becoming more sharp.

“Controlling it so you don’t accidentally get us killed because of your libido is part of your job.”

“I bet Rover doesn’t need to deal with this…” Zach muttered under his breath.

Meanwhile, Rover was wearing a heavy ceramic vest, carrying a 20 mm light artillery cannon, and assaulting a mock fortification with the rest of his howling scout pack. They charged through machinegun fire (paintballs) and only stopped when everyone defending was captured and rounded up in the center. Only three more iterations before the cookout, orgy, and snuggle pile.

“You’re technically correct, but part of that is that lupines are usually expected to act as part of a pack. They have their own methods of regulating their dynamics. I can’t have you giving into your instincts because artillery is going off and you’re stuck cowering underneath Mustang, regardless of how comforting his ass is.

Mustang grinned happily, and grabbed a squat bar, grunting as he started lifting, driving that much more blood into his wonderful ass and, almost as an afterthought, scent glands. There was an immediate impact and Zach felt his own body starting to react, swelling just that much more, and his own need pouring off his sweaty shaft.

“NO! Bad Zach!” Anda barked. She pulled a cloth soaked in… peppermint oil? Whatever it was, it burnt all the way down his nostrils, and left him cross eyed, but the shock did allow him to shrink back down to what he thought of his new natural form.

There the trio stood. Mustang and Anda trading off and tempting Zach, Zach getting exposed to overly potent scents and other sensations that short circuited his brain and reactions, giving him just enough space to control himself. It worked, and he slowly figured out how to shift smaller, but it gave him blueballs from hell, his need aching and burning up and down his entire groin, balls refusing to shrink, even as the rest of his body compacted from an 8 and a half foot tall monster towards a seven foot tall beast.

Gasping, balls aching, dick limp on the ground, Zach sat there, brain blank as the pain and need coursed through his body, hormones for a being at least 20% bigger trying to push him back towards his most comfortable form.

One more shocking scent flooded his brain, as a gentle kiss pressed against his muzzle, a tight hug from behind sandwiching him between his herdmates.

“You did so well.” One murmured from in front.

“I’m really impressed. You’re trying so hard.” The other said, and the tension on Zach’s body relaxed, his shaft finally extending after being kept in aroma therapy chastity (along with ice, lemon flavor, high pitched noise, and many other impressively unwelcome sensations. His thighs still hurt from being pinned against the wall while someone twerked against his face and shoulders).

It was mostly human now, differing only because of a medial ring and in sheer size. As the rest of his body started to relax, he felt a surge of fluid starting to drip from his shaft. It was thick, viscous, and slippery. Clearly intended to ease entry into his mate, or mates. A similar feeling prodded from behind, slipping between his new very stretchy hole, easily opening him up.

“There's a few muscle relaxants in our fluids. Just to make this a bit easier.” The equine behind him murmured, growing large enough to cuddle and spoon Zach, hugging him close, rubbing cheeks. On his other side, Anda gently pressed her chest to his slight muzzle. Her nipples were wet, breasts overfilled, and he could feel the warm fluid stoking a fire inside of him as he started sucking.

With each thrust, his prostate sent happy sparks up his spine, as Anda sat on his shaft, groaning happily as it filled her. She slowly shifted a bit more, allowing herself to sink completely onto him as she started bouncing in his lap. The three were sitting together, safely inside of Mustang and Anda’s cottage. Food was heating up, the scent of flowers, orange blossom, and horny mare and stallion filled the air, and the noise of running water, thunder storms outside, and relaxing chimes filled the air. It was clearly intended to be a safe home for Zach, and he felt his balls swell and unload. His brain, already overwhelmed and barely focused, whited out, unable to even try to think of anything.

The overwhelming sensation was relief. He’d basically been teased for hours on end, It would have been teasing if there hadn’t been some point to it all, but… he was slowly coming around enough to begin to engage with everything around him, tail intertwined with Mustang’s, as he started to bounce, adding his thick and powerful thighs to the group’s enjoyment, pushing back into Mustang, trying to get that extra inch or two, and pushing into Anda, hoping to fill her that much more and help her towards her own orgasm.

The sound of happy equines, slapping balls, and panting filled the air, as Zach’s balls churned, making more seed, his prostate spasming every few minutes as the thick invader expertly pounded the sensitive organ. Zach, for his part, tensed his 8 pack abs, feeling his curved shaft rub against Anda’s rougher inner wall, stimulating her g-spot as she pushed her thumb thick clit against him with every thrust. It was throbbing, as she neighed an orgasm, her ass spasming and begging for something to fill her. She grabbed his hand, and pulled it down over her ample assets, Thick hard thighs melding into built glutes, and a pucker that eagerly accepted one finger, then two, then most of his hand. He’d slipped in up to his wrist before she froze again, gasping, and both his shaft and hand were nearly crushed by another orgasm and her extremely well trained internal muscles.

“Keep fisting me.” She begged when she had recovered from the afterglow. It was a bit awkward, but pressing his chest into her washboard abs gave him just enough room to pull in and out. Anda for her part, pulled his head in between her breasts, loving his strong shoulders and back, as she leaned forward to kiss her husband.

With one last thrust, Zach unloaded, pulling Anda towards him, hand pressing in deeper able to feel his cock pulse and spasm through her inner walls, as his nose was filled by her needy horny scent.

Mustang pulled out, a torrent of thick virile jizz pouring from Zach’s ass. “You want to top me? I know Anda loves pegging a good boy.”

Zach was caught offguard at how much he loved the complement. His dick spurted again inside of Anda, as she pulled off of him, well trained slit remaining tight around him all the way up, trapping all the jizz inside. She stood up and walked over to the chest of wonders, opening it up and pulling out what looked like a cast of Mustang’s dick, including balls.

It wobbled happily as she strapped it into a harness, dangling heavily towards her knees. “You might want to shift up. Mustang loves being pounded hard, and I can’t shrink this like he can.” She said, rubbing Mustang’s ass affectionately He was over the bed, tail whipping back and forth, ass on full display. His dick was inside a… Zach would have called it a fleshlight but the size was a bit impractical for most lighting devices. Flesh recoilless rifle? Flesh RPG? Whatever it was, it was shoved between the matress and the bedframe, giving him something to thrust into. Zach’s dick was still hard after only cumming twice, so he lined up, and started pushing in, letting his heartbeat pick up, feeling the warm rush that he was starting to get used to as his body grew.

Mustang’s ass was well trained, but he didn’t have the same muscles that Anda did. Zach felt like he was gripped in a vice at the opening, but deeper inside was more… lose and open? Anda’s slit was a velvet grip, holding onto him perfectly all along. Mustang’s was more… controlling and concentrated. He expertly teased Zach’s shaft, letting him slide into the well lubricated hole and trying to stop him from pulling out, tightening a bit more around his medial ring, milking a few extra pleasurable sparks with each thrust. As Zach grew, he could feel the hole tightening, Mustang reveling in the stretch, spine arching as he gasped around the sensation. He slowly started growing, just enough to enjoy the stretch. Anda’s strap on slowly pushed into Zach, as her breasts pressed into his back and shoulders, her hard nipples wet with milk.

Zach was pinned between the two, as Mustang’s legs and ass grew, forcing him to adjust his stance, until Zach’s dick was swallowed up to the sheath. It took a few twists and turns, but Mustang groaned happily as Zach pushed a bit further in and got around another twist, sinking that much deeper into the happy stallion.

“Alright, start pounding. I want to see stars.” Mustang said, starting to thrust, pushing back against Zach.

Anda started pushing in deeper, using Mustang’s thrusts to sink an inch or two at a time, until Zach felt pressure inside his stomach. “Yellow.” He said, taking deep breaths. The other two froze.

“Umm… so it sort of hurts here… what do I need to do?”

“Oh, same thing as what I just did. You’re where your rectum bends.” Mustang said, pointing to a spot on his lower belly. Zach’s shaft was bulging far beyond that. “You need to angle it to the right, so it pushes into the colon.”

Zach was a bit confused, and tried to bend forward.

“Let me help…” Anda murmured, and Zach gasped as his asshole was stretched again. It wasn’t as… aggressive as when he’d been double teamed by the two earlier that day, but Anda’s whole hand stretching him along with the strap on was not what he had expected. Nor was how fucking good it felt to have his prostate fingered along the way. He gasped as a spurt of watery fluid sprayed from his shaft, as Anda kept pushing forward. He felt a pressure to the side, something probing a new barrier, then it pushed through and the pain disappeared, replaced with pure sensation as the shaft easily slid deeper and deeper. It wasn’t the same hard spark of bliss that came from his prostate being crushed, but it felt fucking satisfying, and the pain and shock was slowly being replaced with radiating pleasure along his entire asshole.

“Fuck… yeah… green. Just… slow until I get used to this.” He managed. Anda started thrusting, pushing him into Mustang. Zach tried to go with the movement, as his body adjusted, gasping whenever Mustang thrust back, the strap on reaching that much deeper into him with each effort. It wasn’t long before everyone was getting into it, thrusting back and forth hard enough to shake the bed, everyone in a cloud of sweat and happy sex pheromones.

Mustang was the first to unload, his balls pulling up as Zach felt his prostate swell, crushing him within Mustang’s tunnel. He whinneyed happily, as he sprayed what seemed like liters of jizz into the fuck sleeve. Anda started gryating against Zach, expertly flicking the strap-on’s sheath’s edge against his prostate, eliciting a gasp with each movement, milking blasts of pre out of his cock and into Mustang. After what seemed like minutes later, Mustang lay there, head spinning in the afterglow, ass finally loose enough for Zach to keep thrusting, his medial ring stimulating the inner bend, trying to copy Anda’s expert use of the sheath to tease Mustang so well.

He slowly thrust, focusing on making Mustang feel good, as Anda’s hands played with his abs, chest, and balls. She kept thrusting, pushing him towards orgasm, his careful efforts becoming faster and harder as he lost coordination. “You are so fucking hot, you stud.” She murmured, hilting and gasping as she orgasmed from the clit stimulation.

That was enough to send him over the edge. Blast after blast of thick potent virile sperm filled Mustang, his balls churning in their overstrained sack, as his prostate crushed itself against Anda’s toy, his back arched, sparks in front of his eyes, and whinnying loudly. He kept thrusting, ass clamped around Anda, as every muscle was in stark relief as the pure bliss radiated from his entire body. He collapsed against Mustang, gasping, tail tickling Anda’s washboard stomach.

“Fuck… y’all are too intense for me.” He said after he recovered. Mustang passed him a water bottle from a pile near the bed.

“Stud, we’re nowhere near finished. You ready for the next round?”

Zach felt his dick harden again, still inside of Mustang, as his balls complained about still being too full. “Fuck yes.” He said, and Anda started to thrust again.
