Chad darted his eyes frantically and finally he managed to spot the loincloth, who had ended up in a corner near the sink. He rushed there, ignoring his new need to walk upon his knuckles so as to get anywhere. His spine and legs, as well as his feet, just did not allow this anymore. At best, he could awkwardly waddle by shifting his entire leg one way and the other. His entire weight was now pressed upon his arms and humiliating though it was, it was the most practical and unfortunately natural. His arms were so much longer that even if he could stand upright, he'd look ridiculous. Not that his arms were the only problem with his current appearance... He seized the loincloth and put it around his groin and crotch. Hopefully this would stop the transformation! It was his only hope! So he painstakingly slipped the darn thing on, all the while ignoring his brain who kept insisting that the loincloth was uncomfortable, too tight and squeezing his privates that were not only infinitely more comfortable swinging in the fresh breeze and thanks to his movements but were now so impressive and jaw-dropping in their massive size that it would be a shame to hide them. At long last, with grunts and frustration, Chad had tied the loincloth. Except... If his privates were covered, more or less, his butt seemed awfully to show itself to the eyes of any onlooker. He touched his cheeks and saw that their surface seemed to have changed indeed. His butt really did look bigger! And not only that! It looked also rounder, much more so than before. And... And much more pert! Like... Like a hot chick's ass! He turned around and his eyes confirmed what his touches had hinted at. What was going on? And then more changes hit him, precipitating him into his new body and life.
First, he saw his hair become real fur and blacken. He became shorter and his muscles melted away like butter under the sun. He saw his fingers become smaller and stubbier, just like his toes, while his skin became darker too. He sensed a pressure upon his chest and fascinated and horrified, he witnessed boobs appearing. Boobs just as pert as his new butt and full and plump, the nipples raising themselves enthusiastically upward. He touched and prodded them, mesmerized. They were like water balloons. He giggled stupidly at the thought. They were full of flesh, not milk, but plump and pert for sure. Then, a slight pressure on his crotch made him wince and he looked inside the loincloth. Horrified, he saw his testicles retreat into his skin and form an ovary each, settling comfortably into their new anatomical position and leaving a uterus, cervix and birthing canal in their wake. As for Chad's penis, from becoming an arrogant monster, it shrunk and divided itself, leaving Chad with a clitoris and labia, all small but cute and plump. Young and fully ready to use if required, bursting with vitality, youth, lust and pertness. Yes, Chad was getting quite lusty indeed, with a silky beautiful pelt. So engrossed he was at his gender swap that the changes upon his face went unnoticed. His facial features became smaller, daintier, more delicate and his eyes bluer and larger. His waist got more slender and his waist wider, perfect for child-bearing. Or rather, baby gorilla-bearing, because that was what Chad now was. A female gorilla and the loincloth fell off him, now completely useless. And a real gorilla wet dream was Chad now! The embodiment of pert, lust and adorable! Only perkiness was missing but as Chad still possessed his male human mind, well, this was normal. Panicked, Chad ran around, wanting his masculinity back desperately.
"Oh, what a cute nubile girl!" gushed a voice. "You'll have many admirers in the zoo, I'd wager."
Chad turned around. He, well, now she, could see Damian, a gothic nerd he and his jock friends loved to bully.
"Hello, Chad," he smiled. "I'm not only a goth punching ball, you know. I'm also a warlock. And the means for your punishment. You're the first. Your moronic friends will follow. The loincloth, if you'd put it right, would have made you into a male chimp. Backwards, it transformed you into a female gorilla. You should have been more careful. Although I doubt your life as a chimp, even male, would have pleased you. Lots of responsibility within a group. As a female gorilla, and a very hot one, all will b e provided by your mate. Stupid and lazy as you were, it's best. You can raise babies too and understand fully what being female really is. Have fun!" he finished, smirking and snapping his fingers.
Before he knew it, Chad was transported into a cage in a zoo, about to face his new life whether he liked it or not. As for Damian, he had lots of other bullies to punish.
