A now female skunk padded around on top of Tom's clothes, oblivious to everything that was around it. Matt muffled his own laugh, shocked at what had just happened but somewhat bemused at the same time.
"Tom? You there?" Matt asked. He only got chitters in response as the skunk sniffed at the empty bottle.
Matt moved carefully off the bed, amazed.
"I gotta take a picture of this," he said, taking his phone out and quickly zooming in. "Say cheese roomie," Matt teased as the flash went off.
Startled by the sudden light, the skunk's tail stuck up and sprayed, the soak wetting Matt foot to head.
He spat and dropped his phone, trying to wipe himself off as he got the first big whiff of it. "Oh man," he groaned, not knowing how he would get the smell out. Soon, though, the groans came less from annoyance and more from discomfort as his knuckles felt sore as did his neck, toes, hips and soon all over.
And he felt hot.
Matt grabbed at his shirt, pulling it off and revealing a body starting to look more thin. His torso starting to drip with sweat, Matt felt his brow leaking too before a tug at his nostrils soon grew a yank and cracks were all he heard.
"Ahhh!" he screamed, his face pushing forward, teeth toppling out only to be replaced by new, sharper ones that fit the new dark nose and muzzle that was forming. Matt could only watch, wide-eyed, unaware his ears were stetching and sprouting fur. Meanwhile, he had lost over a foot in height while a tail was already sprouting, black fur and white stripe pluming, behind him over his drooping pants.
"This isn't fair I, I," Matt tried to reason to the bottle, stepping forward and out his shoes and then socks, his pants falling and soon he was on all fours, his hands and feet cramping and forming into paws. "I didn't drink, I, I don't wanna..." Matt whimpered, feeling his cum leak out his diminished cock.
Thankfully he felt his balls swell somewhat, filling with seed while his sheath took his face into the growing black fur of his stomach. There was some relief that came with the sudden surge of hormones. Matt could feel his whiskers coming in and even let out a small spray of his own as the final changes set in.
He looked up and saw Tom from behind, tail still raised. A whiff of the air revealed a heat that had Matt's new skunk cock sprouting anew.
Matt 's last human thought, as he mounted and thrust into his roommate was that they should have never opened that case.
Had they somehow been able to resist the urge, they would have found the potion lasts an hour but, as Matt finished into Tom, their changes became permanent. Their fates sealed in a skunky smell.
