I've been fantasizing about my girlfriend's stepmom for weeks. That MILF has an ass that won't quit. I know it's risky, but I can't stop thinking about slipping my dick into her tight ass without getting caught. I need a plan. Maybe when my girlfriend's not around, I can make my move. I just have to be careful. If we get caught, it's game over. But the thought of her juicy ass makes it all worth the risk.
