BOLD! Stepbrother fucks me while she sleeps!

I wanted to make just getting ready to go out with some friends, when suddenly my stepbrother was a mega-bar in front of me in the bathroom. His girlfriend, a total bore, sleeps next door in the bedroom !! Yes I can not blame him but that he wants to take full advantage of the situation, the bathroom door closes and takes me through really nice! Otherwise, he never goes so for the shot! He had me already in his spell when I saw his hot, hard spanking .. I just can not resist .. Whether his girlfriend has probably noticed what?
