Reprogrammed his mind.

Scott and his sister Gemma swapped bodies by accident when one of their dads experimental devices blew up in the basement.

Scott was the typical nerdy kid at school and his sister was popular and beautiful and was going out with the school star quarterback who always picked on Scott.

Scott was only doing this to annoy his sister he had no intention of being her for the rest of his life & he was definitely not interested in her idiot boyfriend.

Scott placed his small delicate hands around the waist of his sister's boyfriend as his sister watched from inside his body not believing Scott was acting so girly around him and Scott could not believe the feelings welling up inside this female body as he soaked in the musky scent of the men's aftershave which disturbed him as he was getting sexually aroused in his sister's body.

Hoping that she could not notice what was going on between them as his crotch felt like a waterfall as they both plan to meet up after school that night for a little bit of extra curricular activity.

Scott can not believe his first sexual encounter would be with his sister's boyfriend in her body but the attraction between them both was irresistible and Scott new now his sister had true feelings for this man as her raging female sexual hormones reprogrammed his mind and he could not stop himself from falling deeply in love with this man and his sister's body.
