You’re fucking your girlfriend until she starts talking about your Stepmom, and she realize you’re getting even hornier and your cock starts throbbing inside her pussy. She starts talking about how you’ve always fantasized about having sex with your stepmom and how you’ve always been spying on her naked and jercking off to your own stepmom. In the end, she asks you to suck on her motherly breasts as if you were feeding, and you cum inside your girlfriend while thinking about your stepmom.
