Barry sighed and shook his head, the two titanic breasts on his chest jiggling.
He had woken up before Katie and shockingly viewed his bizarre new body the best that he could (its hard to see with two huge, vertically-stacked, breasts in your field of vision) and hobbled around on newly-placed legs cautiously as he exited the alley and began to witness strange transformations.
A woman with a body about three times the size of the average man, appeared almost entirely unchanged before Barry saw her face - it was dominated by a single large vagina. She struggled to pick herself off of the ground, having just awakened, and produced muffled shrieks before she sat down and unbuckled her belt and pulled off her strained pants, now too small for her. A large mouth with a large pair of smacking, luscious lips was crammed between her legs, and it was gasping for air. The woman walked bow-legged so that she could breathe as she then pulled off her now-tight shirt. Her two breasts had grown each two eyes, all four of them frantically surveying the area as the breasts bobbed up and down. Their nipples had been replaced with vaginas that were smaller versions of the one on the woman's face. The large woman tried standing up but kept on losing balance and falling, each time with a small thud as she landed on her buttocks. It was then that she and Barry both realized, as the woman maneuvered one of her breasts and her torso to get a better view, that her legs ended in hands. With this realization, the woman walked, somewhat like a non-hopping frog, on all fours, completely naked, over to a storefront. She removed the cloth awning and wrapped in around her midriff before gingerly making her way away from the scene, careful not to step on terrified mutants and untransformed individuals much smaller than her, or any cars.
Two naked adults made their way gingerly onto the street and within view from out of a store - they were both clothed in shredded rags that had to be those of young-teens. They were hugging each other as they walked and each holding a hand of a small girl wrapped in a large, clearly adult dress, making it difficult for Barry to tell what had happened to them other than the obvious age regression and progression, but eventually it became clear. The upper body of the now-adult girl was placed on the lower body of the now-adult boy, and the upper body of the now-adult boy was placed on that of the lower body of the now-adult girl. The now adult girl was poking and exclaiming at her new, hardening penis before the young girl leading them gasped and swatted her hand away. The only other change that Barry could see was that the now-adult girl was missing visible breasts, apart from nipples. Judging from the bulges in wrapped dress of the adult-turned-young-girl, Barry deduced that she had likely achieved breast growth instead.
