I slept with my stepsister when she turned 18
Do you think it's okay to sleep with your step-sister?
It was an awesome moment in my life.
It's frowned upon to sleep with your step-siblings, as they are your close family members. You shouldn't sleep with your step-sister again as most people will look down upon you for it.
I seriously can't find any reasons that would stop me from doing it again.
Well it's heavily frowned upon, and I'm sure if your step parent found out they'd be furious.
