When I was around 12-13 I kinda molested my cousin while she slept.

I would slide down her pants and just rub her and lick her pussy while she made faces but never woke up. At the time my mom, being Christian, didn't tell me about sex or anything. It was just an urge.

But now my cousin has grown up (sophomore in high school) and seeing her in a choker, tight jeans, and V-neck showing off her great tits gets me so hard and I want to fuck her.

Im not sure what to do, I can't even masturbate because I'm visiting and staying at her house.
