Would it be wrong to fuck my stepbrother again?

Gross!! I can't believe my stepbrother just came in me! I told him not to, but he did it anyway. The only way for me to feel somewhat clean again is to take a shower and wash that jerk's cum out of me.. But as I try to wash it away, I start getting extremely horny. My fingers travel down my body and I start rubbing my cum filled pussy. The thought of fucking my stepbrother to keep my secret turned me on so much.. Right when I feel like I'm about to cum, he barges into the bathroom! Omg what are you doing!? You scared me! Whatcha doing stepsis? Did I catch you in the middle of something? I'm trying to take a shower!! Can I join? -My stepbrother smirks at me and jumps up on the bath tub with his rock hard cock out- Dude stop, stepMom and stepDad will be home any minute!! Come on, I know youwant it back in your mouth, I can tell by the way you're staring! I know it's wrong to fuck my own stepbrother
