Step-Sister Fucks me to Stay out of Trouble

I recorded my step-sister out by the pool celebrating 420. She NEVER gets caught doing anything and I get in trouble for things I didn't even do. So, now it's time to put HER on step-dad's SHT list. Or, maybe I will let her off the hook, I mean, she looks SO good in her little bikini, and I know she is an absolute slut... So Dana has been pretty bitchy since we fucked. She can't be that mad, I know she got off on my cock. I just need to give her an excuse and she will be all over my dick. I wait in her room and catch her sneaking it WAY after curfew. She is pretty pissed at first, but, the slut in her takes over once she sees how things are and I think she is going to be a little more open to messing around from now on.
