Loving...yet nasty...incest? (Must like anal)

[Assficianado]

I'd like to write a one shot brother/sister story. The two of them will be young...15 or 16...but there's been a strong sexual tension between them for years. They'll have the most awesome,nasty sex,yet they'll treat each other as they always have. They'll feel some guilt, but they'll agree that they get off on knowing they shouldn't be doing it.

This is a one-shot, but you must care for the story...no one or two paragraph posts. I don't need a wall of text, but show me that you're into it.


I love the intimacy of anal incest, so she must love...or at least like...anal sex and being rimmed.

I'm more than happy to include your kinks and cravings, and if we enjoy it we could keep it going.
