Taking Advantage of Step-mom in the Shower

I'm taking a shower and someone peeks out watching me, I notice that you are watching your stepmom with an obvious erection but I pretend that I don't see it, until it becomes more and more big and you surprise me naked! I scold you because I have already told you to knock before entering the bathroom. After all, there may be someone occupying it, but since you are here I tell you not to be ashamed of seeing me naked and to massage my back with sulfur soap. But oh, you're getting closer and closer to the forbidden zone no matter how hard I try to move, I want to keep pretending that it's your leg that's rubbing against me until you pound me against the wall and penetrate me. Your faith is right behind us washing his hands so I cover my mouth so as not to moan so loudly, but the more your mother tries not to make noise, you fuck me harder, faster, and deeper and make my hips move abruptly on your erect cock...
