Kelly opens a can of foaming drink and takes a sip, which seems divine to her. She drinks more, feeling shaky and excited.

She began to feel her body heating up and wondered what was happening to her, or maybe the soda was something else. Her olive-colored trousers turned dark blue, and her legs got bigger, so she had to take off her shoes. Her legs were feminine and graceful, and her toenails were covered with green varnish, but at that moment the varnish began to crumble, the foot increased, and she relaxed. Her toes had lengthened, her foot was swollen, and now she had two, well, male, very beautiful legs. By the way, at that moment she felt that her panties had changed their texture, now it seemed that she was wearing black boxers, her trousers had lengthened, and she had turned into beautiful dark blue men's trousers. At that moment, she already understood what was happening to her.: She turns into a boy, namely her boyfriend Blitz. The transformation continued: her brown crop top turned into a simple gray T-shirt with a red pattern, she felt her D-size breasts shrink into two large male breasts, her stomach, always flat, filled with several well-developed abs, her vagina began to burn, and her penis also began to grow, she felt aroused at the same time, she grew brown pubic hair that reached for her penis, now she had a PENIS AND TESTICLES, and they were big. The brown color was noticeable on her trousers, her heels turned into a pair of men's shiny dark boots with red soles, and on her feet appeared men's white socks, a black jacket, a thin long scarf tied around his neck, matched her outfit, now she looked like a handsome guy with a feminine face. She sees an androgynous girl in the mirror, but she continues to drink, enjoying the taste and moaning. The nanorobots transform her body, breaking down fat and building muscle. Kelly admires her manly reflection. His face began to change, becoming more masculine and freckles appeared, a black bandana with a red pattern appeared covering the lower part of his face, and round red glasses gave the image of mystery. His graceful hands began to enlarge and fingerless gloves appeared on his hands, and the veins began to stand out from the exercises he was doing, and his hair began to shrink, and now he had slightly disheveled brown hair that gave him a sloppy appearance. His hair looked so soft. She has an adam's apple. He looks in the mirror, enjoying the view, and lets out a loud laugh. He gets taller and bigger. The pain goes away, but the feeling of intoxication remains. Kelly touches her biceps and abs, giggling. He becomes a full-fledged man, an exact copy of his boyfriend, without a shadow of femininity. Kelly rubs her neck and makes a purring sound in her new voice.

With bewilderment in your eyes, you look at the half-drunk Kelly, who has become your boyfriend.
