Collin stumbled forwards a few steps and tried to figure out
what had happened. His waist felt broader and with growing
concern, he felt his butt and tights slowly growing...

“What?!...no!” In panic, Collin saw his trousers slipping down his legs again.
A dark patch of hairs was slowly growing out of his boxers. “where do these come fro-”

He stopped as he felt a warm liquid filling his boxers – had he just peed himself?!
He slowly pulled his boxers down again, as a weird tickle started on his chest.
“What the...?!” he saw the shoes he had just put on starting to bulge and
deform, like his feet inside were moving in a pretty unnatural way. It didnt
took long until his toes felt numb and immovable and a few seconds later,
Collin screamed as dark hooves ripped free from the remains of his footwear.

“She... Ugh... she forgot the prevention!!!” Collin tried to hold his balance with his
new, weird hoof-feet. His lips felt numb and swollen, and as he touched
it in disbelief, he noticed that it had almost tripled in size and volume.

“Whut awe thif?! Bimbo-lipf?!” he stammered, but the changes in his crotch
made him forget his swollen lip pretty fast: A thick bush of dark hair had
grown a few millimeters above his cock... well or what was a cock once.
Most of his proud member had receded back into Collins crotch,
only with his former glans sticking out of what seemed like a fleshy
hood that slowly grew tighter and closer towards the new hairy bush.

His testicles had disappeared – or rather morphed into soft
fat-pads that slowly formed the outside of a wet, dripping pussy.

Meanwhile, the tickle on his chest had grown even worse, and in a mix of
horror and disbelief, Collin saw two massive bulges protruding out from his chest.
