Drinking a Gay TF Potion

Diagnosis results On their way through the dungeon, User W the adventurer and his travelling companion come across an alchemist's workshop full of potions, all unlabeled. User W decides to take a sip of one at random, getting a funny feeling in his stomach, and suddenly his adam's apple becomes noticeably engorged, causing his voice to drop by an octave, while he lets out a large burp, then his belly lurches forward, fat and soft, finally coming to a stop when his nipples grow until they are an inch long, thick as erasers, and extremely sensitive. User W's companion, feeling massively turned on, takes a sip of another potion. He also gets a strange feeling in his stomach, and suddenly he starts feeling compressed, and begins shrinking until he is 11 inches shorter, while his cock starts shrinking, becoming a useless 1 inch nub with balls the size of small grapes, finally stopping when his ass starts filling with muscle and soft fat, becoming so sensitive he cannot control his moaning as it jiggles up and down. Both feeling extremely horny, they begin stroking themselves, until User W starts mounting his companion. After User W cums, it all goes into his companion's asscheeks, engorging them to several times their previous size.
