My friend sees me studying on the bed in my underwear and approaches me silently, he unzips his pants, takes out his cock filled with cum and starts rubbing it against my buttocks and my lovely pink panties. I don't make any noise, I let him imagine that i'm not aware that he is playing dirty and that his behaviour is wrong. I let him go on anyway. Just the thought of that makes me extra wet, and my pussy begs to be penetrated every time I feel him rubbing against me. My family is in the house and we can't make noise, but a little silent rubbing can't hurt anyone, can it?
