Sibling Rivalry: A Transgender Body Swap Novella

by Cara Hart

Fed up with his sister's rants about how hard her life is, Miles finally snaps at her, hoping she’ll take his advice and learn to finally chill out. Instead, he wakes up as a girl the next morning—and his crazy sister won’t turn him back until he admits she was right. Well, screw that. If she’s going to mess with him like this, then he’s going to spend the next week proving her wrong. Being a girl can’t be as hard as all that, surely?

Thrown into a glimpse of a life he’s never known, Miles soon finds himself in a whirlwind of shopping, attention and parties that he’s never even bothered with as a guy, but…well...it’s not all bad. And if he happens to catch the attention of the guy his sister has been obsessed with all year?

Well, she’s only got herself to blame.

This is a 52k word body swap transgender novella, featuring a guy suddenly thrown into a girl's body and discovering things about himself that he's never known. It contains feminization, experimentation and transgender themes, with some explicit moments.
