GFE: Old-Fashioned Parents

You've taken your girlfriend to visit her parents for the weekend. Even though you two have been living together, her parents still don't feel comfortable with you both sharing a bedroom. Graciously, you accept the big beanbag chair in the basement. Your girlfriend reassures you that her parents are just being silly, and that you can expect a visit from her later that night. Even though you're nervous about getting caught by her step-dad, you can't help when she tempts you with her big voluptuous titties. Even though it's incredibly risky, you have to fuck her massive boobs until you cum all over them.
