Clay

The shrill sound of the alarm clock going off beside Clay's bed disturbed his gentle slumber. "Oh fuck," Clay groaned as he rolled out of bed and rubbed his eyes. As usual he was the first one up in the morning. Clay's fist came down hard on the innocent alarm clock and the abused device fell silent. He slowly stood up from his bedside and stretched. Right about then he noticed his junk flapping around below him. The huge flaccid member looked almost too large for a guy who was only six feet tall. It seemed odd to Clay that he was naked, but when he looked down at his bed he noticed his boxers laying amongst the covers. "Musta shucked them in my sleep," he said and scooped them up off the bed. The fabric smelled faintly of soot and sulfur, and there were rips, along with burnt spots, down the front of the ruined clothing. "What the fuck?" Clay asked and frowned before he tossed the boxers into the garbage can beside his bedside table.

While he was getting dressed Clay noticed that his groin was irritated and his skin was puffy and red. It itched terribly, but before the young man could get another pair of boxers on he was distracted by how good it felt to sit on his bed and scratch his cock, balls, and the area around his taint and groin.

Down the hall in Rex's room a sleepy-eyed dog heard Clayton moving around his room. Spike squirmed out of Rex's arms and made his way towards where Clay was sitting on his bed. The eighteen year old male jumped in surprise when his door creaked open, but when he saw spike he sighed. "It's just you," he said and absently went back to itching his cock and balls.

Spike woofed as he noticed the irritation on Clay's genitalia. Without a second thought the small dog went to work licking the inflamed skin, and like magic the burning sensation stopped. Clay was surprised by Spike's affection at first, but as the burning stopped he began to relax and moan slightly. The hot saliva was thick and slimy at this point; it clung to both skin and hair like glue. Clay couldn't help but to start working the thick slime into his itchy skin. Before too long he was hard from stroking his fifteen inch cock.

A low moan was the only sound the young man made as he unconsciously jacked off. The sensation of Spike's snout closing over the tip of his cock distracted Clay enough to make him look down at the dog and frown. Spike gave him a look as if to ask why the hell he had stopped. "What the fuck... ohhhh shit," Clay said as his cock clenched and a gush of pre shot into Spike's mouth. The dog eagerly licked up the sweet man-juice and continued to slather copious amounts of slimy drool onto Clay's cock.

Before he knew what he was doing Clay started to jack off again, working the excess drool onto his balls, into his thick brown pubes, and across the rest of his groin. The sensation of warmth, and the relief from the itching, made the whole process feel intoxicating to the young man. He moaned loudly as the drool began to soak his hands and then his wrists. The sticky slime hung in trails off his body, but Clay didn't care anymore. It felt so damn good! Before ten minutes had passed his pre was starting to thicken and shoot out violently from his cock. With a final loud grunt Clay exploded into the hungry cub below him. The volume of cum was so great that Spike couldn't help but let a little of the liquid food ooze out from between his doggy lips.

It took a while, but Clay finally finished cumming into the dog's small mouth. Spike went to work cleaning Clay's sticky cock and groin, coating it in even more gooey slime. The stuff was so thick it was starting to dry and darken in color, turning a strange black and red color as it dried. Spike was still hungry though, but what he did next was even more shocking to the teen. As Clay lay chest-up on his bed spike walked over to him and began licking his nipples. Right about then Clay realized his nips were just as irritated as his groin was, but he hadn't noticed this fact until Spike had started licking them.

As soon as Spike's lips closed over Clay's right nipple the cub began a steady sucking motion. A sensation like nothing the teen had ever felt rocked his body. A strange clench shot through his pectoral muscle extracting a groan of pleasure from the young man. He couldn't see the jet of mike that splashed into Spike's puppy mouth, but he could feel the clenching and the sensation of burning hot liquid shooting through his nipple. When Spike had drunk the right nipple dry he moved over to the left, giving it a loving coating of slimy drool before sucking it too. Again Clay was shocked by how good the clenching felt as he fed the young cub. "What the fuck is happening to me?" Clay groaned in confusion as he watched Spike drink from his tits.

When Spike finally drank the left nipple dry Clay groaned and looked over at his bedside clock. "Oh FUCK!" he said as he bolted upright. Spike looked at his naked form in confusion as the man ran around his room. The drool on his chest and groin quickly dried and left strange trails of black and red residue on the young man's muscular torso and lower body. By the time Clay put his shirt and jumpsuit on he was far too distracted to notice the pleasant throb of heat coming from his pecs and groin. "Gotta go Spike!" He said as he ran downstairs. On his way out the door Clay banged on Bo's door and shouted for him to get up. "Bo! Make breakfast! I'm running late today!"

"Ohhhh shit," Bo moaned as he rolled over in his sleep.

"I mean it Bo. Get up and make breakfast for Hunter and Rex! Ok?" Clay shouted in a firm fatherly voice that sounded... surprisingly forceful even to Clay.

"Yea, yea, I'm getting up," The sleepy teen said from the other side of the door.

Clay hurried downstairs and gathered up his wallet and keys. He didn't have a cell phone or anything like that, so he just ran out and jumped into the family's only vehicle--an old beat up red truck. The engine sputtered and groaned as Clay turned the key in the ignition. It was a good thing he was handy with cars because he had to fix the damned truck all the time. The drive to work gave Clay a chance to think and relax. He hadn't eaten that morning, but he didn't usually have time to eat so that wasn't unusual. What had been strange about his morning was the blow job he'd gotten from Rex's puppy. Spike sure had seemed bigger that morning than he had the night before...

When Clay finally pulled into his work parking lot he sighed and shook his head. There was only one other truck in the back parking lot behind the car shop, but Clay didn't think anyone was inside it. He cautiously unzipped his jumpsuit and pulled his shirt up so he could touch his nipples. The drool that had covered them was dry now, but it had left a strange black and red powder behind. Clay ignored the filmy powder and began to tug on his firm nipples. After a few curious tugs he got a pattern going and like magic the amazing clenching sensation returned. The first few clenches only pushed a few creamy drops of milk from his nips, but as he worked himself up the clenching got stronger. Before a whole minute had passed small white jets of milk were shooting out of his nipples.

Clay couldn't see it, but across the parking lot a curious young man around his own age was watching him in mute fascination. Even from his seat in his truck the young man could tell Clay had something squirting out of his pecs. "Fuck me," the guy said as his cock hardened at the sight of a hot muscular stud milking himself in plain view.

After a few pleasurable minutes of exploring his strange new ability Clay stopped himself and groaned as he felt the hot milk running down his muscular torso. "This is so fucked up," he said as he wiped the milk off his chest and the dash of the truck. It left a musky smell behind, and it smelled a bit sour to his nose. He didn't realize it, but the smell was distinctly sulfur-like only it was much muskier and not like rotten eggs at all.

The door of the old red truck opened and closed as Clay hopped out and jingled his keys cheerfully. He made his way to the back door, but before he got there a young man around his own age came jogging up to him from the direction of the unfamiliar truck. "Um, hey!" The young man said and smiled at Clay, "I'm Markus... the new guy?" Mark added the question to the end of his statement when Clay didn't seem to give any indication that he knew what Mark was talking about. "Dave told me you would show me the ropes today."

Clay's cheerful mood evaporated as he scowled at the young man. All hopes of getting any work done today had been washed down the drain with the appearance of Markus. "The new guy huh?" Clay grunted rudely as he turned the keys and opened the back door of the shop.

Markus followed Clayton with a sad expression on his face. He had been so excited when he got his job here, and seeing a hot stud, who was obviously around his own age, had only made things better. But it seemed like Mark's new co-worker didn't care for him much, and they had only just met. "Um... did I say something to upset you?" Markus asked.

Clay ignored the question as he motioned for Markus to follow him through the darkened shop. They were inside the offices at the moment, but Clay had to clock in before he could do any work. "Please tell me Dave showed you how to clock in," Clay said gruffly and ignored the other male's nervous expression. Mark shook his head and cursed silently as Clay grunted and turned back to the screen. The gruff young man quickly typed some things into the computer before turning back to Mark. "You'll need to fill some shit out before you can clock in. Try not to take too long," Clay said and stood, leaving the room without giving Markus any more instruction.

As soon as Clay was out of the office and back into the shop the phone rang. Clay hurried to answer it, hoping it was Dave calling to tell him where the hell he was at the moment. "Clayton!" A cheerful voice said after Clay answered the phone with their normal phone greeting.

"Hey Dave," Clayton said and frowned despite trying to sound cheerful, "Where are you?"

"Ugh... well you see... I had this thing that popped up, and now I need to run off to visit my brother in Alaska." Dave explained. Judging from his voice he didn't sound like he wanted to talk about whatever had happened. "I figured you could watch the shop and train Markus while I'm away."

"Yea, about that..." Clay said and tried not to sound too negative, "How much does this kid know about cars?"

"Not much, so you'll need to start with the basics and move up from there." Dave said almost a little too cheerfully.

"What!?" Clay said angrily without much concern for his tone of voice. "I can't teach him and keep this place running by myself!"

"Oh about that," Dave said and seemed to rummage around on the other side of the phone, "I promoted you to manager while I'm gone. You should be getting more money now, but you have to do all my work too. You might want to train Markus in how to do the office work too, because I'm not going to be back for a while."

Clayton's jaw was hanging too loosely from his face for him to reply to that bit of news. "Y... you made me manager?" He asked in shock.

Dave laughed on the other end of the phone. "You've been running this place with me since you were fourteen. I think you can handle it. Ok? Don't give up on Markus either, he's a good kid; he just needs someone to look up to," a sound on the other side of the phone distracted Dave for a moment, "hey I gotta go, but don't forget to do all the paperwork while I'm gone, and remember what I said about Mark too."

The tone of the Dave's voice reminded Clayton of how he had spoken to Bo that morning. "I'll try my best," Clay said wearily.

"Good to hear it. Take care bud," Dave said before his line clicked and the man was gone.

Clay hung the phone up on the wall and groaned. Right about then Markus emerged from the office with a sheepish grin on his face. "I finished with the first screen, but now it's not doing anything... I hope I didn't break it..." Another groan was all Clay could manage as he turned to Markus and walked over to him. "Um... What's your name?... ugh... sir..." Markus asked nervously.

"Clayton Burns, but call me Clay. Ok?" Clay said and put his hand on Mark's shoulder. "Let's go get this straightened out before we get any further behind today..."

...Rex...

School had just let out and Rex found himself walking home with Spike following close behind him. He had tried to make Spike stay at home, but the dog had yapped and whined so much that Rex thought he was going to hurt himself. He had let the dog come with him despite fearing that someone would scoop him up and carry him away. Fortunately, Spike didn't seem to like anyone but Rex and his brothers. The little dog growled and snarled at anyone who even approached Rex. At first it was cute, but when the other kids started avoiding Rex on the walk to school it made things a little awkward.

Thankfully Spike had waited patiently outside the school for his master to return. When Rex finally emerged from the building his excited dog bounded up to him and barked like mad. Now the two were walking through the park, but Rex knew he needed to stop at the pet shop instead of going straight home. As soon as he walked through the doors Mr. Park greeted him and then Spike, who seemed to tolerate the man a bit more than he had the day before. "He sure seems to be growing fast," Mr. Parks said cheerfully.

Rex nodded in agreement. "He sure is," Rex said and paused in thought before continuing, "and he doesn't seem to eat any of the puppy chow either..."

"Maybe he's just nervous, some dogs get that way when they're in a new home." Parks suggested. "How did your brothers like him, did he growl at them any?"

Rex chuckled as he remembered Spike's reaction to each of his brothers. "They loved him, and I think he likes them too."

"That's great Rex. I knew that sending that dog home with you was a good idea." Mr. Parks smiled at Rex before guiding him through the shop. "Well then, we better get started with these boxes. I have all sorts of things that need to be lifted and carried, and I'd like you to start with these over here..." Rex quickly started helping the elderly shopkeeper who seemed to be quite excited to have him around.

Spike watched from the side of the pet shop while his master worked. Every once in a while someone would wonder into the shop and Mr. Parks would greet them politely or ask if they were looking for something. Nobody really paid attention to Rex or the dog sitting in the corner of the shop watching him.

Two hours flew by while Rex worked hard to finish up the various tasks Mr. Parks had asked him to do. "Is there anything else you needed done before I leave?" Rex asked.

"Oh no, not really," Mr. Parks said and smiled as he reached into the cash register and extracted a twenty. "I know you only worked about two hours, but you earned this today. It would have taken all afternoon for me to move those boxes of dog food around."

Rex accepted the money and slipped it into his wallet. "I think I might take Spike out to play in the park. You don't mind if I go a little early today?"

"Not at all," Mr. Parks said and reached behind the register to extract an old beat up Frisbee, "You can have this one on the house, it came in all beat up anyways. I can't sell it to anyone, and maybe Spike will enjoy playing with it?"

"Thanks Mr. Parks!" Rex said and accepted the Frisbee. "Hey Spike!" He said and held the plastic disk up. Spike jumped up excitedly and wagged his tail at his master, "wanna go play Frisbee in the park?"

Spike barked and danced around in a circle. Rex just grinned and held the door open for his excited dog. "You two have fun," Mr. Parks shouted after them.

The park was full of other kids playing with their dogs. Spike was a little too small to play with the big dogs, but he sure loved running after the Frisbee, and he would even bring it back to Rex whenever he picked it up. Rex was a ways off from the open area where the other kids were playing when he happened to throw the Frisbee extra hard. It flew through the air and sailed into a thick patch of bushes. "Spike wait!" Rex called after the small dog, but Spike had already disappeared into the thick vegetation.

A quick dash to where Spike had run into the bushes revealed that there was enough space between the ground and the bushes for Rex to crawl through them. A soft bark from inside the darkness of the foliage made the teen groan as he dropped to his knees and crawled into the dense vegetation.

It didn't take long for Rex to reach a small clearing in the middle of the bushes. He sighed as he sat down and wondered where on earth Spike had run off to. A familiar bark heralded the appearance of Spike who had the Frisbee clutched in his mouth. Spike dropped the plastic disc when he saw Rex sitting against the trunk of a small tree that had prevented the bushes from growing too much in the clear area they occupied. "Spike, I thought I had lost you" Rex said in excitement as his dog bounded over to him and jumped up onto his chest to lick his face.

The thick slimy drool tingled when it touch Rex's skin, but after a quick hug Spike lost interest in Rex's face and turned to his groin. The cub-sized dog whined as he sniffed at Rex's groin. Rex frowned as his dog relentlessly pawed and sniffed at his concealed cock.

"What's wrong boy?" Rex asked, but Spike only whined louder and gave Rex a pitiful look.

Rex cautiously undid his button and unzipped his fly much to Spike's delight. The dog kept sniffing at Rex's groin making the teen laugh and blush. When Rex pulled his pants down and his cock flopped out the small dog went nuts. Rex had been itching his junk all day during school, but it wasn't until now that he noticed how angry and red his skin looked. Rex didn't have time to scratch his cock though, because Spike quickly took the flaccid member in his snout and began to suckle on it hungrily.

"Oh shit," Rex moaned, "that feels really good boy." Rex pet Spike as his dog growled softly and took as much of the cock into his mouth as he could fit. As all nine inches of Rex's cock thickened and hardened Spike began to drool onto the dirt causing small puffs of smoke to blossom up from where his droll hit the leaves. Rex looked down at his dog in wonder as he noticed the smell of smoke.

Thin wisps of smoke wound up into the air floating around the human and his dog like tiny specters. Spike sucked and drooled causing the smoke to wrap around them; lazily making a slow whirling circle as Rex moaned in time to Spike's soft growls. As more smoke joined the swirling cloud, the pleasure caused Rex to close his eyes. He didn't see what happened next, but it happened regardless.

As the human began to reach climax the mini-tornado of smoke was rapidly pulled into him when he closed his eyes and took a great big breath. Rex didn't notice the sensation of breathing in all that smoke because to him it was as if he had breathed in a great warm cloud of pure pleasure. The warmth spread through his young body and traveled straight to his groin. When Rex finally did cum it was the most incredible sensation he had ever felt. A loud gasp was all that signaled the resulting explosion of thick spunk that shot into Spike's mouth.

Rex tilted his head upwards and groaned loudly. He didn't notice that the seed leaking from around his dog's mouth was a dark gray color instead of the usual white. To Spike it was like drinking liquid energy, and as he slurped down the torrent of cum a soft crack was the only indication of his body growing past its eighth inch of height. Rex was too busy groaning in pleasure to notice his dog pushing upwards in height and backwards as he lengthened. Below Spike something new began to develop under the young cub. A few drops of thick black slime dribbled down from the tip of his sheath in response to his growing arousal. The tip of a blood-red cock emerged from Spike's small sheath as he looked at his master in a whole new light.

Once Rex was emptied, and practically panting from the constant orgasms that had rocked his young body, he reached down to pet the small dog below him. "Good boy." Rex said in a dazed voice and then grunted in pleasure. It was a while before Rex summoned the energy to pull his cock back into his underwear. The liberal coating of spike's drool had satiated the intense burning down there, but the wet squishy feeling made Rex grin sheepishly. "We'd better get out of here and head home," Rex said as he noticed how late it was getting.

...Clay...

The sound of their last customer for the day pulling out of the garage and heading down the road was the best sound Clay had heard all day. He watched as Markus hurried to finish putting up the oil and some of the other supplies they had used on the last car and throughout the day in general. A slight smile crept across Clay's face as he watched the young man work. Through the day Clay had learned more than he really wanted to about Markus. Apparently he was Clay's age, and from how he talked he was somehow related to Dave. That made sense when Clay thought about it, Dave and Mark both had the same light-hearted manner, not to mention the same curly red hair. Mark still had most of his hair though, and he was a lot smaller than Dave was in the weight department.

While Markus cleaned up Clay made his way over to the office and sat down in the chair. He idly reached up to stroke his nipples and grunted softly when he found that they were still rock hard. They had been hard all day, and it was difficult as fuck not to play with the damned things. Clay thought he had been pretty damn sneaky about touching himself that day, but Mark had watched him absently stroking his nips all day long. Clay didn't know it, but he had left the door to the office wide open, and after Markus finished up in the shop the curious eighteen-year-old wondered over to where he had seen Clay disappear too.

The sight that greeted Mark was an instant turn-on. Clayton was grunting a little more loudly as he pulled on his nipples. His jumpsuit was stretched tight over his pecs which had been growing larger through the day. Mark quietly snuck into the room and up to his new boss. The touch of the young man's hands on Clay's shoulders surprised the newly promoted manager. "You look tense," Mark said and started to slowly massage Clay's shoulders causing the man to instantly relax.

"It's just all this shit with Dave leaving..." Clay said with a low grunt, "I hate when he does shit like this."

Mark didn't reply right away, instead he worked his hands across Clay's back and shoulders, noticing right away how thick and solid the man's muscles were beneath his jumpsuit. Carefully, and with an expertly smooth motion, Mark reached around to unzip the front of the jumpsuit. His hands slid the garment down making Clay blush a bit, but the closer contact with Mark's skilled hands felt intoxicating. A few times through the massage Mark would venture down and deftly graze the top of Clay's rock hard nipples. Each time he did that Clay would grunt in pleasure and Mark would smile behind him. "You know," Mark said as he worked the knots out of Clay's shoulders, "it might help if you took your shirt off." Mark suggested innocently, but he was secretly dying to see Clay shirtless.

Without even thinking Clay pulled the shirt over his head and absently dropped it beside him onto the open filing cabinet. "How's that?" He asked and looked up at Mark who was smiling happily.

"Perfect," Mark said as his cock throbbed and rubbed against the back of the office chair between himself and Clay. The two huge slabs of muscle that made up Clay's chest were even bigger than Mark had imagined. The thick cords of Clay's pectoral muscles stretched the skin above them tight. Below the two perfect pecs was a six pack that any pro-athlete would be jealous of. Mark thought he could just make out the tops of two small hairy mounds deep in the darkness of Clay's jumpsuit, but the adventurous young man was content with rubbing Clay's shoulders... for now at least. There was also something producing a thick and musty down there musk down in that blissful darkness. As soon as the shirt was gone and Clay's jumpsuit was pulled down to his waist that same potent musk filled the small room making Mark swoon just a bit. There was no way Clay was wearing underwear under his jumpsuit if he smelled like that!

Mark refocused on the task at hand, and Clay seemed to relax even more as the shoulder massage worked down onto his chest. Mark rubbed and pounded the rock hard muscle until his hands found the two painfully hard nipples pushing up into the air. The teats were about the size of a dime now, and they were almost a quarter inch long. As soon as Mark ran his hands over the slightly dark flesh of Clay's nipples the man grunted in pure ecstasy. What happened next surprised Clay enough to make him open his eyes and watch as Mark circled around him and knelt down so that he could take one of those huge hard teats in his mouth.

A low moan was all Clay could manage as a hot hungry mouth encircled his teat. Mark began to work up a good rhythm as he sucked on his manager's huge nipples. Before too long a sweet creamy taste filled his mouth causing Mark to open his eyes in shock. He watched as Clay grunted and his pec seemed to flex in a rhythmic clenching motion. The man's hand came around to hold Mark's head down against his rock hard chest. A second squirt of milk filled Mark's mouth with creamy richness and Mark grunted in surprise again. In only a few short moments Clay was holding the back of Mark's head and groaning in pleasure as the man drank his burning hot milk. The temperature had shocked Markus at first, but he quickly grew accustomed to how hot the milk was.

When Clay's right nipple was empty Mark released it from his mouth and sighed in content. Clay watched as steam came out of the young man's mouth and nose filling the air with a strong musky odor. Before Clay could stop him Mark attacked the left nipple and repeated the process of extracting milk and low groans from his boss. It was well past six by the time the two finished and Mark stood up from in front of Clay. "God, that was hot," he said and breathed out a second musky plume of steam.

"How are you doing that?" Clay asked and chuckled as he pulled his shirt back on, and zipped up his Jumpsuit.

"What?" Markus asked and breathed out a third plume of steam, "that?"

"Yea," Clay asked and moved in real close. Before Clay could object Mark leaned in and kissed him passionately. As their lips met the young man blew his fourth plume of smoke into Clay's mouth. It puffed out Clay's nose and wrapped around both of their heads. Mark sucking his teats had been hot, but kissing was even hotter. When Mark finally pulled back he wiped his hand across his mouth and the long string of saliva Clay had left there. Even the man's spit was thick and viscous in texture. Mark was hooked.

"I think I'm going to like this job," Mark said and scooted past Clay to clock out. "I'll see you tomorrow... boss."

As he watched Markus leave Clay shook his head. What the hell was wrong with him?

...Rex...

That afternoon everyone was weirdly quiet at dinner. It was taco night, and that meant it was Rex's turn to cook. There were no leftovers, but at the table nobody had really wanted talk about their day. At long last Clay seemed to sigh and shake his head before speaking. "So how did your day go guys?" He asked the whole table, but nobody answered right away.

"Me and spike went to the park after work today," Rex said excitedly and then pulled the twenty out of his pocket. "I also got some money from Mr. Parks for helping around the shop!"

Rex tried to hand Clay the money, but Clay shook his head and pushed the bill back towards Rex. "You keep that money Rex, you earned it," he said and smiled at his brother. Rex wanted to believe Clay was proud of him for working, but he seemed distracted by something.

"So how did it go at the shop today?" Rex asked and looked across the table at Clay.

"It was... difficult," he said and thought for a moment before replying. "We got a new guy in today, and Dave is gone for a while so I have to train him."

"I could come help out if you want?" Hunter offered.

"No!" Clay said a little too quickly and loudly. "Sorry Hunt, I just... it's not that... I have some... err... problems with the new guy that need to get worked out before he meets any of you guys." Clay seemed a bit embarrassed by his outburst. He went to work on his fourth taco before anyone could get more information out of him.

"I guess I should get a job too huh?" Hunter said vacantly. "Even Rex works after school now, and it's pretty quiet around the house with everyone gone and whatnot."

"Why don't you take Spike to school with you tomorrow?" Rex suggested. "He waited for me during class. I bet he'd wait for you too."

Hunter perked up at the thought of bringing Spike to school with him. "You don't mind?" Hunter asked and smiled at Rex.

"Naw, he's your dog too." Rex said and smiled back at his brother.

After dinner Rex went upstairs while his brothers cleaned up the kitchen. Clay went to bed almost as soon as the kitchen was clean, and honestly Rex was feeling a little tired himself. "Must be all that running around," he told himself as he peeled his clothes off and fell into bed. Rex was careful to take his underwear off this time. He didn't want to rip up another pair tonight like he had the night before.

Spike wasn't too interested in sleeping yet, so Rex left his door open. He guessed the dog would come and go through the night, but he didn't really know just how much his canine friend, or his brothers, really did 'come and go' through the night.

The dog in question was downstairs watching Hunter and Bo work out. The two brothers attacked the weights with a passion. They didn't really spot much for each other, but they were both pretty worked up that day. Neither male had been having a very good day, but they didn't want to talk about it with each other. Instead they talked about the only other thing in the room they shared an interest in. "Spike sure is looking big," Hunter said as he looked at where the dog was sitting in the corner of the gym.

"Sure is," Bo said casually and examined the slightly larger canine from the other side of the weight bench, "maybe he was older than Rex thought he was?"

"I wonder what kind of dog he is?" Hunter asked and frowned. "I've never seen a dog with red stripes like that..."

"Huh," Bo grunted and looked at Spike, "I didn't notice those till now."

The conversation ended as the two refocused on their workouts. When they were done Hunter went upstairs to shower and Bo used the downstairs bathroom. While the two young men were busy Spike stole into Rex's room and found the young teen fast asleep. The dog waited patiently for the sounds of Hunter and Bo's snores to float into the hallway before he nuzzled Rex, causing the young man to roll onto his back. A huge cock flopped onto the young man's belly, but that didn't stop Spike from growling softly as he started to lick the flaccid member.

Rex roused slightly from his slumber as his dog gave him a blow job. "Good dog," he moaned and fell back asleep as his cock hardened enough for Spike to do more than slobber all over it. Drool oozed down Rex's cock and balls covering most of his groin while Spike serviced the nine inch cock in his snout. As usual Spike took his time lavishly painting Rex's groin with sticky drool. Spike dutifully attended his master with a tender attention to detail. Of all the brothers, Spike loved Rex the most. Something about the young human just drove Spike crazy. It took a while, but eventually Rex exploded into his dog for the second time that day. His grunts were wild and low as his gray cum sprayed into the hungry dog's mouth. Having only barely recovered from feeding Spike earlier, Rex didn't have a whole lot of cum to give. His orgasms were strong but short lived as he quickly emptied his cum reserves for his dog.

After feeding from his master Spike made sure to coat Rex's groin, cock, and balls in a thick layer of slimy drool. As the drool dried it soothed and warmed the young man's exposed skin. Unfortunately, Spike was not satisfied with the meager meal he had received from Rex. The hungry dog hurried down the hall to hunter's room. Unlike his brother, Hunter had opted to wear underwear again, but Spike was beginning to become an expert at removing the annoying cloth garments. In very little time the thick black and red saliva that oozed out of the dog's mouth had burned the offending cloth away. Numerous trails of smoke circled the bed as Hunter's 11 inches rose to salute Spike. Just like with Rex, Spike gave Hunter a good coat of thick black drool all over his groin before he turned his attention to the young man's cock. The angry red rash-like inflammation he had suffered with all day cooled for the first time since it had started. Before Spike started to service Hunter's cock the teen sighed in content. Spike was glad he could help the human with his burning rash.

Hunter bucked and groaned as Spike swallowed his cock for the second night in a row. The dog was looking a bit bigger now that he had fed twice on Rex that day, and he was able to take nearly nine inches of Hunter's cock into his hungry maw. His stretchy body oozed black drool around the young man's member causing it to pulse as it absorbed the corrupted slime. More and more drool soaked into the skin of his cock causing the heat and pleasure Hunter felt to grow steadily. A funky odor began to waft from the young man's exposed pits, and for the first time in his life Hunter began to growl softly just like a dog might growl. Spike noticed that Hunter's body seemed to absorb the corrupted black drool the dog had slathered onto his body far faster than the other humans. The heat and pleasure were growing more and more intense as time passed. Hunter took one last breath before he exploded into the dog with a loud snarl. The smoke from his burning undergarments, and from where the drool had dropped onto the covers, pulled into his nose as he came. The cum that sprayed into the dog was a dark gray, just like his younger brother's now was. Hunter gave Spike a much bigger load than he had the night before, and as the dog fed on his rich seed his body cracked and groaned in response to the incredible surplus of food.

By the time Spike prowled into Bo's room he was looking much more dog-sized and less like an overgrown puppy. Drops of drool fell from his mouth making small black dots on the old brown carpet. The smoke circled Spike and followed him through the darkness like a wraith. When he saw Bo laying spread eagle on the bed with pajama pants and a shirt on Spike growled in frustration. It was a bother to the canine, but he dutifully started with the shirt. Spike began to chew and gnaw at the offending garment, but instead of tearing in his teeth the fabric burned instead. More smoke joined the mass hovering around spike as he pulled the last of the shirt off and promptly began to chew it up in his mouth. The martial smoldered and ignited on contact with his saliva. Spike leaned over Bo's crotch and breathed the smoke and ash onto the young man's groin. The heat from his breath quickly burned away most of the fabric adding to the smoke swirling around them.

A low growl was the only sound Spike made as the smoke and ash swirling around him darkened and thickened. Next he pulled what was left of the pants off Bo's body and chewed those to embers as well. An intense heat baked the air in the room, but thankfully nothing else caught fire as Spike began to slather his thick black drool all over Bo's huge 13 inch member. The drool clung to the teen's skin as Spike's long black and red tongue began to wrap around his throbbing member. It took some creative positioning for the dog to pull the cock into his mouth, but eventually Spike was growling as he worked himself over Bo's manhood. The young teen grunted as the smoke began to pull into his nostrils. Spike was delighted to discover that he could lick and drool all over Bo's exposed groin while he sucked on the teen's cock. The young dog was easily taking just over 10 inches of the 13 inch monster, but his tongue was almost long enough to slide into Bo's taint now. Whenever the drool would touch the bed sheets the fabric would darken and smoke dangerously. Spike spread his ashy black drool all over Bo's groin, but the bed never actually caught fire.

At first only a few wisps of smoke snaked into the young teen's nostrils causing a warm sensation to spread through his body, but as his climax approached the smoke began to thicken and pour into Bo. His grunts sounded odd through the black and gray cloud surrounding him and Spike. Whenever he would reverse his breath twin plumes of inky smoke would shoot from his nostrils, but they were quickly pulled back in when he took his next breath. Just before his orgasm began Bo took a deep breath and the all the smoke in the room funneled into him at once. The sensation was similar to having liquid fire poured into his lungs, but Bo hardly noticed the sensation through the explosion of pleasure he felt in his loins. He couldn't have woken even if he had wanted too at that point, and a low gruff grunt was the only sound he made as his cock clenched and shot the biggest load Spike had eaten so far that night.

For the second time that night Spike experienced a small growth spurt as his doggy body packed on size and muscle. While his body grew larger Spike's tail began to lengthen a bit as well. It seemed oddly long in proportion to his body, but his paws were also very large, so the long tail wasn't too odd looking. Spike's growls were beginning to sound much more like those of a dog well past his second or third month of life. Spike's grunts and growls were deep and low, but still nothing like the rumbling snore that came from the last room in the hallway.

A low grating snore was the only sound Clay made as Spike prowled through the darkness of his room. Clay had been so tired that night that he had fallen asleep in the shirt he had worn to work. He had slipped on a pair of boxers to keep his junk from flopping around while he slumbered. Spike didn't have to waste his black saliva on Clay's clothing to burn it away from his body. A quick breath of searing hot air did the trick, and, just it done when Spike was with Bo and Hunter, the smoke swirled around the dog like a phantasmal cyclone. It wasn't until Clay was completely naked that Spike went to work on his titanic cock. It didn't take long to slather thick black drool all over the man's cock and groin. Unlike Hunter and Bo the rash Clay had developed was starting to heal. Spike growled in delight as the dog noticed Clay's brown pubic hair was starting to thicken and darken in color.

Spike growled as he valiantly tried to take as much of Clay's fifteen inch cock into his snout as possible. It seemed like the dog could still stretch his jaw and throat to accommodate the huge cock just like he had done the night before. Clay eventually reached down to assist the dog, and Spike realized that the young male had woken up. In the darkness of the room the sex dazed Clay could barely make out anything in the mass of smoke swirling around him. He did, however, know that Spike was greedily swallowing his huge cock, and it felt magnificent! "Good boy," Clay moaned in his sleep as his cock began to clench and gurgle. It wasn't a true orgasm, but it was pretty fucking close. Spike was delighted when his stomach began to fill with the thick jets of pre shooting from Clay's cock. Not only was there more pre than the night before, but there seemed to be no end to the liquid oozing from the man's massive member.

The influx of food fueled Spike's growth, but instead of growing larger something else began to grow under the young dog. For the first time in his life a thick four inch blood-red cock pushed out of Spike's sheath. The black juices dripping from the dark tip of his tool seared the covers on top of Clay's bed. Before too long the whole room was filled with smoke from the smoldering bed covers. All Clay could do was groan in time to the dog's growls. He was distantly aware of the stream of smoke pouring into his lungs, but the heady warmth spreading through his body was much more distracting than the smoke itself. Easily twice as much smoke as what Bo had breathed in entered Clay's lungs as he filled the dog below him with jet after jet of pre.

If Clay could have seen his seed he would have noticed how it had gone from white, to gray, and then to black, mirroring the thick slime dripping onto the charred remains of Clay's bed covers. It was a miracle that the bed didn't catch fire, but that would have hardly stopped the two as more and more smoke poured into Clay's body. "Spike," Clay said in a voice that only barely sounded human, "Oh, good boy Spike." Clay's thrusts quickened as more of his cock slipped into the dog. The head of his cock was just entering Spike's stomach when a heat like nothing the man had ever felt shot through his member. It was like he had stuck his cock in liquid magma, but it felt so damn good that Clay could only groaned in delight.

The cloud around him was quickly drawn into the man as Clay took in a huge breath just before he exploded into Spike with such force that it felt like the molten heat in the dog was actually pushing up Spike's throat! An inhuman growl escaped Clay's throat as his eyes rolled back in his head and a sensation like nothing he had ever felt rocketed through his body. The young man came into Spike for a solid twenty minutes, but Spike didn't grow much bigger than he had been before entering Clay's room. Instead, the cock below the dog surged forward doubling in both length and width. The small balls hanging behind Spike sprouted thick shaggy fur and doubled in size as he drank from Clay's titanic cock.

Clay had long since passed out when Spike pulled off his spent member. The long black tongue that extended from Spike's mouth was forked and punctuated by thick red ridges that were each about three inches apart. The tongue itself was around nine inches long now, and Clay was being lavishly coated in thick black drool as the small dog painted his groin. Spike worked his endless supply of drool across Clay's stomach and then his huge chest as well. A soft groan was all Spike got when he got to the man's nipples. Clay rolled over unconsciously, allowing Spike easier access to the milk producing teats on his chest. As the thick black drool dried on Clay's chest and groin his pecs provided a huge meal to the starving dog below him. Spike drank Clay dry well before morning, but the dog was hardly satisfied by the meal.

Spike dripped both cum and drool onto the carpet as he returned to Bo's room and found the young man naked on his own ash dusted bed. The smoke following Spike through the bedroom snaked up and towards Bo's nose. It curled and twisted as it was pulled into his thick muscular chest, but Spike hadn't returned for more of Bo's seed. Instead Spike went to work on the young man's nipples. Coat after coat of black drool was painted onto Bo's chest by Spike's nine inch tongue. All the while Spike dribbled pre from his cock onto the bed covers providing a steady flow of smoke to the young man's lungs. Before too long Bo was grunting in time to the clenches of his pecs. Just like Clay, the second oldest brother proved to be a good supply of nourishing milk, and for the first time that night Spike was beginning to feel full.

It was a little past three when a large well-endowed dog crept back into Rex's room. Spike found the young man sleeping on his stomach when he jumped up on Rex's bed. A warm nose pushed into Rex's ass crack as Spike began to investigate his master's backside. When he found Rex's ass hole the dog began to lick the tight ring of muscle, his corrupted black drool coated most of the teen's ass before Spike began to get a little more adventurous.

Rex gasped in his sleep as Spike pushed his forked tongue past the tight ring of muscle. The dog growled along with his master's moans as the long black and red muscle violated Rex's virgin ass. A new kind of hunger began to build inside the young dog. His growls changed in tone from cute and puppy-like to low and dominating. Rex was still far bigger than Spike, but that didn't change what the dog wanted from his master now. After a gallon of Spike's thick black drool had soaked into Rex's backside his body was ready to take the eight inch monster lurking under his dog's belly. Spike mounted his master with a low growl, but Rex hardly grunted at all as his ass was pierced by the pointed tip of Spike's cock head.

Spike's cock was shaped like a wolf's cock, but his head was a bit thicker and his pointed tip was slightly rigid. The extra solidness to the cock head made spearing Rex's hole all the easier, but Spike worked slowly into his master despite his own lusty desires. A steady rhythm of pulling out and plunging his blood-red cock back in provided Spike with equal parts pleasure and progress towards hilting himself into Rex's ass. Before a half hour had passed Rex was taking Spike up to the two bulging bulbs at the base of his eight inch cock. Spike was too horny at that point in the mating to bother being gentle with his knot. Each time the dog pounded the solid bulge against Rex's ass hole the ring of muscle stretched a little wider and a bit more of the knot slipped inside. At long last Spike slammed into Rex with enough force to make the young man grunt in his sleep. The huge knot popped into his ass with a resounding squish, and Spike began to drool uncontrollably onto his master's backside.

Spike didn't stop humping as the first of his many loads sprayed deep into Rex's ass, the dog worked his knot deeper and deeper into his new mate. Using the last inch of meat behind his knot, Spike was able to continue humping and thrusting into his master. After a solid ten minutes of pumping thick black cum into Rex the dog collapsed onto the human's back. Rex sighed as the warmth of his canine lover seeped into his body. A soft crack came from the human below Spike, and as the dog laid on top of Rex the young man's cock began to grow hard again. As it thickened the cock lengthened as well, filling with blood and creeping into its tenth inch. Rex only groaned as he unconsciously began to rub against his bed sheets. His cock had lost its rash, but it was beginning to darken in color now. The mushroom shaped head was slightly deformed by the growth of a small point that formed along the side of the cock that faced away from Rex's body. In truth, his cock was beginning to resemble the member shoved into his ass, but Rex wouldn't wake up until long after Spike had pulled out of his backside and licked it clean. Before morning came Spike had curled up with his master and was sleeping in Rex's arms. Even if he was a little larger the dog still looked cute curled up next to Rex like that. They would sleep that way well into the next morning.
