Grabbing the dark grey supplements from her desk, he promptly excused himself, thinking he’s being slick in stealing without her noticing. Todd then slips back into his office, shuts the door, and pulls the blinds closed. He takes them raw and swallows them hard, not taking into consideration how large they are. With his throat sore, he grabs a warm juice from under his desk. He burps loud and excuses himself as he starts to get hot. He starts to unbutton his shirt and take off his undershirt as he noticed his abs starting to swell and his chest getting covered in sweat. He felt like he was getting bigger, his torso getting longer and his legs stretching out further. With his privacy, he also took his pants and boxers off to feel his cock grow. From a limp 3 in mound with grape-sized balls to a 6 in pecker, finally settling around nine before it started getting hard. As he started getting erect, he started to itch. Creme-colored fur covered his body in a thin layer at first, completely unnoticeable to the naked eye. Then he feet started reshaping, his toes morphing together as they turned into hooves. His ass and thighs swelled out more, giving him a slightly pear shape. The fur came in thicker as hid cock and balls started growing, his member now a 13 in half chub with walnut-sized balls. He kept stroking it as his chest puffed up a bit, his muscles getting even more definition across his body. His spine extended as a tail began to form with black, wirey hairs appearing at the tip. His ankles down to his new hooves feet also started getting black hairs appear on them. His hands got a little bigger as the same black fur covered them as well. With him closing in on an orgasm, he looked for somewhere to aim as he grabbed a trash can and hastily out it over his now 18 in flat tipped horse dick. He came large loads as his face started reshaping into a horse’s muzzle. His hair grew out into a mane, turning two-toned (black and brown) as it grew down his neck. Keeping his cock in the bin, his let it fall naturally as he started getting soft, making sure not to spill a drop of cum on the floor. Once he felt like his new baseball sized nuts were empty enough, he went to assess the damage he did. He snorted to himself as he saw that half the bin was full of musky horse cum. Cleaning himself up, he tried to put his clothes back on, only to find that nothing fit anymore, either my him being too tall or too muscular to fit into his former skinny boy clothes. Just as he though his transformation was over, his stomach grumbled as he bent forward slightly and pushed out a loud, rude fart that made his tail flutter. He didn’t know where the cramps came from, but it made him start sweating again as he could no longer control his new ass. Not only did he look like a barn animal, he was now beginning to smell like one too. ‘Todd you stupid colt, Auntie told you to make sure you had some diapers on you, and then this happens’ began to sound out in his mind. He didn’t like the way that sounded and his stomach wasn’t calming down. Seeing no other option, he squatted his massive horse ass over the tiny trash can and laid some increasingly wet farts into the cum-filled bin.
