Your older sister Crystal

You were slightly relieved when it was your sister She looked like she just came back from a cosplay event from an anime you don't remember. She then smiled walking over to you. "Hello Dory. It's so strange seeing a boy err girl now with only a pussy. Hmm still you look delectable. I've only told mom I'll be picking you up... But I decided I'm going to take your first time. I can't stand the thought of some uncuth oath messing up your first time just jack hammering away at your pristine virgin pussy." She then starts to undress what little clothing she's wearing already hard as she stalks towards you.

You try to run only for her to press you against the nearest wall her left hand pulling your panties down as her right holds your hands above your head as she hungrily kisses your now soft feminine lips as a rush up f conflicting emotions hit you.
