Pretty soon the coupled settled into their rooms and into Dr. Changs gas traps and their bodies were wheeled into the sub basement.
"What do you plan oh doctor" his assistant said.
The doctor smiled mischeviously.
"first I will swap the athletic guys head and genitals onto the heavyset womans body, keeping his clothes of course. He will still keep his athletic, high energy personality but I want to add getting exhaused earliuer from her personality to his."
"His wife of course will be lacking the easy exhaustion and have his body but with her own genitals."
"The busty blondes head will be placed upon the fat hairy guys body, it'd be interesting to see how her seeing other girls as jealous of her body will be effected when her body is male."
As for the muscular guy and the asian girl, swap their skins and skin features. She'd have his rough hairy light skin, little male nipples, head hair, and her genital skin would be dry and wrinkled like his ball skin. While he will have her smooth tanned skin, female nipples, and the skin on his genitals would be pink and moise like hers.
