Thomas stared at the studded collar in his hands. The senior high school student had found the item in a cardboard box that his neighbour had thrown away after a rather loud argument with her husband the previous day. He didn't know exactly about the details, but among some kinky stuff like dog masks, leashes, whips and leather clothes, he had found the collar and discreetly taken it for himself. He had to sneak the collar inside as his parents wouldn't have approved of him taking it from his neighbours' trash.

Since Thomas' parents went grocery shopping earlier, he was all alone in the house and thus had no risk of getting caught looking at this item – his parents had the bad habit of intruding in his room whenever they felt like it. Taking it in his hands, he stared at it intently, fascinated by it. It was fairly thick, sported two rows of inch-long spikes, and had a single metallic ring on one side. On the inside part of it, there was something he assumed was a label, but in reality was a warning to inform people to never use this item when alone. Thomas stood up and approached his cabinet, opened it to have a look at himself in the mirror. The high school student wasn't exactly remarkable in any way, he was a 5'5 tall lean man with dark brown hair. He opened the side release buckle of the collar and brought it around his neck, securing the accessory on himself. Trying to see if there was a way to fasten the collar to not make it look ridiculously loose on him, the young adult didn't realize that changes were already occurring throughout his body.

As Thomas continued fumbling with the collar around his neck, his skin became very itchy. Too preoccupied by trying to tighten the device, he failed to see how his body was changing. Thick body hair was growing all over his body; around his neck, chin and mouth, on top of his head; over the top half of his pectorals and over his groin as a thick treasure trail. Not only that, but several structural changes started taking place: his ears were moving up on the sides of his head, the front of his face elongated while his nose flattened; his toes were growing in breadth and height; his heels rose off the ground; his tailbone was elongating and on each of his still nonexistent abdominals, nipples began sprouting. His body also began packing on more beef with every second, it was like a sort of instant workout for him; his muscles were heating up and throbbing with power as they grew visibly. To accompany these changes, his jaw was widening, his shoulders were broadening, his chest was puffing up and his neck was swelling. Thomas stopped trying to fumble with the collar, giving it up, and looked at the mirror again. His eyes shot wide open as he saw an image he already didn't recognize anymore. He had already grown to almost six foot tall, was particularly hairy – especially on the beard and moustache – and his jaw was getting squarer by the second. Confused, the transforming man's mouth fell agape. He could see in the mirror that even his teeth were elongating. Despite this being the weirdest thing that ever happened to him, he couldn't help but enjoy what he was looking at. He was becoming a manly and muscular piece of hunk.

Something felt off for the young adult, though. His ears were slowly moving higher up on his head and his nose was flattening even more, making him look like he was growing a snout. When a short and rough brown fur began spreading from his beard and eyebrows to cover the rest of his face, he was sure of it. He was becoming an anthropomorphic dog. The structure of his body underwent additional changes, his thumbs were retracting back into his hand, his fingers were shortening and broadening and his fingernails became claws. Not only that, but the small nub of flesh growing from his ass elongated further and started wagging, his ears flopped down on the sides of his head, his canine grew into fangs, and his toes became even broader as his feet transformed to canine paws. Unconsciously, he began wagging his newly grown tail, and let out his elongating tongue to pant audibly. Within his underwear, his cock began erecting as it too underwent some changes: his shaft was covering in fur and his foreskin was growing thicker to become a large sheath that was quickly expanding in volume, and his glans began transforming into a pointy tip before growing in girth and length as blood was pumping into it.

Thomas looked at the mirror in front of him and stared in disbelief as he reached 6'6 tall, with his previously baggy clothes completely overfilled to the brim. Even the bulge in his pants was obscene. An unbearable horniness took over him, making his whole body ache and beg for release. His balls, which were growing bigger in his underwear, were sloshing and churning as they were preparing a load of cum. Loud rips started echoing in his room as his t-shirt tore open, revealing his growing chest, hardening abs and five rows of expanding nipples. The pitbull's pants followed suit, ripping open around the thickening calves and thighs, and his socks were next as they tore around the massive toes. Aside from the studded collar, his underwear was the last piece of clothing that was still holding out, though it was creaking around his growing body. Thomas tried to bring his hands to the piece of cloth, but his hands had transformed into large paws that lacked opposable thumbs, making it difficult – if not impossible – to grip the fabric to get rid of it. Helpless, the transforming man fell on his knees just as he reached to seven feet in height. He let himself fall on all fours on the ground and looked at his reflection in the mirror. The transformation kept going, making him beefier, taller and more endowed by the second, but he was now too lost in his horniness to care. His erection was growing fast, tenting and slowly tearing up his underwear, adding so much strain that it ripped at the tip of his cock and freed the massive red pillar that was contained within. It wasn't even half hard and it was already well over a foot of throbbing pre-leaking shaft. His balls expanded in width yet again, making the last of his underwear tear open, thus freeing the massive bowling ball sized orbs that were now free to dangle between his massive thighs, only a couple inches away from the floor.

Now completely bare, Thomas climbed on his bed, desperate for a release. Not even bothering to get comfortable, he pressed his cock against his bed sheets and began rocking his hips back and forth. Every time he thrusted forward, his dick erected a little more, freeing an inch from his massive sheath. Not even half a minute in his romp with the mattress, his cock had already reached to two feet and a half in length, poking him in the chin and leaving just the knot inside his oversized sheath. His arousal was through the roof, yet his orgasm felt so far away. Because of how much pre his enormous dick was leaking, half of the bed sheets were drenched in the liquid. His ten large nipples were still expanding, the thickest one being the ones on his pectorals, standing at three inches in width and two in length, and all of them began leaking milk, with the largest being the leakiest. Unable to find relief with just his bed, he stood up from it again, noticing that he had grown to seven feet and a half, that his balls had become pumpkin-sized and were now dangling between his knees. He went to his mirror and laid his massive shaft against it, while pressing his pectorals forward, simulating a sandwich-frot with another guy as large as him. With his cock trapped between his chest and the mirror, the horndog began bucking his hips in another attempt to reach the release he longed for. Every thrust made his ten nipples splash milk that splattered over his cock and over the furniture, sending bolts of pleasure to his brain. He was getting closer to his climax, but it was still not nearly enough. To eight feet he grew, and his rumbling balls were now twice the size of a large pumpkin, and resting well on the ground. The sheer amount of fluids that was shot from his nipples and from those cum tanks was enough to make the cabinet completely drenched and dripping.

But nothing was enough to bring him to his orgasm. He stopped humping against the cabinet and swore he could have heard his parents coming back home. Although, he was too horny to confirm that they were, nor did he care at all. He fell on all fours again, used his front paws to squeeze his pectorals against his cock and pressed his chest down, thus sandwiching the enormous cock between his gigantic muscles and the carpet floor. Like a beast in heat, he began humping at a fast rhythm. Every time he thrusted, his arousal soared to greater heights, thus making his balls churn and grow with more cum. He reached a point where finally his sheath unveiled the titanic knot hidden within; it was wider than his waist, and brought the monument of virility to four feet and a half. Thanks to his knot being freed, the head of his shaft was now right in front of his muzzle, and so he leaned to lap at it while humping ever faster. Because the cock was trapped under his chest, the knot was rubbing against the three lower sets of nipples, sending shivers through his nervous system as he humped back and forth in a desperate attempt to reach his orgasm.

“For the fourth time, Thomas," yelled his mother from the floor below his, “can you fucking come down and-“

He didn't need to hear to anything more than that. This simple word, “come", was enough. He obeyed, eagerly, and groaned from relief. His brain was assaulted by the immense pleasure that had been accumulating and waiting to be unleashed as he finally reached the release he had longer for. Like a dam whose gates were opening, his cock fired an immense blast that loudly splattered against the wall and against his desk. His computer, school supplies a calendar, several empty bowls of cereal were all washed up by the tidal wave of cum fired by the horny dog. The cumshot was powerful enough that when the seed splashed against the wall, splatters flew to every piece of furniture in his room; over the bed, over the desk, over the cabinet, over the walls, over the ceiling. And that was nothing but the first blast. A second one was unleashed, washing up the few things that had survived the first wave: mugs, his computer's monitor, gaming controllers and much more. Nothing survived this second wave of cum. The whole wall in front of him was completely covered with seed that was dripping down and starting to pool. The closer to the wall, the more cum accumulated. Two inches had already pooled under his desk and the liquid was slowly spreading towards him, soon touching the underside of his cock. Lost in bliss, Thomas rose up on his knees, put both his handpaws on top of his cock and pressed down on it, panting and tongue lolling out.

As the third blast of cum began, there was already an inch of cum over three quarters of his room, with his desk being completely covered with several inches of the liquid that was dripping down. His balls were quickly shrinking, emptying of their contents as the enormous cock of the young man was firing blast after blast. His whole room was a mess of cum, man milk and whining pitbull.

“Thomas?" yelled his angry mother “don't make me repeat myself, I asked you something!"

Panic started settling in the pitbull. His orgasm had started weakening, and he would be in trouble if his parents him like that. Even though his cock was still firing plenty of cum, the pitbull undertook the task of cleaning the mess. The only idea he got to clean it all up was to try to lick it all clean. Though, as soon as his tongue touched the liquid pooling on the ground, a shiver ran down through his spine and all the way until his balls, which swelled a tiny bit as they instantly produced a gallon of fresh semen. This time, though, he would have to hold back the orgasm or he'd really be in trouble. Every lapping and swallowing of his own seed made his cum tanks grow larger, sloshing with an ever increasing batch of the liquid. He had only managed to clean a foot square of the carpeting when he heard the handle of his room's door squeak. With how positioned he was at this moment, his cock was aimed directly at the door, and his balls were taking up about a third of the room, which meant that the orgasm building up at the moment would me a lot more impressive than the previous one.

“Thomas, what the fuck was all that noise?"

Thomas wanted to speak, to tell his mom not to come on in, he wanted to beg and cry, but nothing other than weak growls and barks came out of his mouth. As the door was opening and the frame of his mother was appearing, he began whining in shame.

“Thomas, When I ask you to..." began his mother, who stopped in her tracks as she saw the mess in the room and the enormous pitbull with a gigantic cock as large as his thick torso aimed in her direction. She was completely stunned, and the only thing she managed to do was to finish her sentence, “come..."

Thomas closed his eyes and obeyed the order once more. His balls rumbled and began pumping the freshly produced cum through his urethra. Seed was fired at the unsuspecting woman, and Thomas' climax began flooding the corridor and the entire house. He'd be in serious trouble because of that, but he didn't care as his brain was overloaded with pleasure as his cock was firing blast after blast after blast of cum out of his room.
