You decided on a headswap between a man and a woman working out together in the gym. Both were in their late twenties. The man was about 6' 1" tall and was pretty well muscled, he had short brown hair and a sizeable bulge distorting the front of his black short, which he wore along with a white vest, socks and sneakers. The woman, his friend, had to be about 5' 6" maybe, had her red hair secured in a ponytail and was pretty decent looking. Her best assets though were her perky C-cup breasts.
Again with just a mere thought the swap was made, the pair's heads now adorned each others' bodies and then continued working out, only it was now the man on the rowing machine and the woman lifting weights. But you weren't content at doing that alone.
"Maybe she'd like her intimates back." You thought, as your face pussy got wetter by the second. The formerly muscular man, now with the woman's shapely body kept rowing away even as his new tits melted into his chest, replaced by his old chest, completely with chest hair. And his crotch erupted... as his former 8-inch cock bulged out the front of his new lycra women's shorts.
The woman underwent the opposite changes as her now masculine body suddenly gained her own tits and pussy back. They were now the right gender again, but with different body types.
Satisfied, you looked elsewhere in the gym.
