This wasn’t supposed to go like that. You weren’t supposed to lust over your best friend’s little sister. Not the girl you’ve known since you were three. Not the girl who used to trail behind you two, braces glinting and hair in messy ponytails. Not the girl who used to call you “nerd” every time you corrected her grammar. Not the girl who is now… very much not a girl anymore.

It started slow. A look too long at her smile. A laugh that curled too easily in your chest. The summer heat didn’t help—bare legs, sun-kissed skin, and that confidence she carried like she knew exactly what she was doing to you.

You kept telling yourself it was harmless.

She was off-limits.

Well.

Fuck limits.
