Your girlfriend is so happy you came over today: she has a little surprise for you. She starts by showing off her new top and how easy it is to pull it down exposing her perfect little breasts. Stroking your cock she tells you how much she loves getting you hard and seeing the precum drip out, biting her lip as her boobs bounce to the rhythm. You move to the couch and she gets on top, grinding her hips into you as her tight little pussy grips your cock. She rides you for several minutes, moaning with pleasure, until she asks if you want to know her surprise. She stopped taking her birth control, which means if you cum in her right now you could get her pregnant. She tells you she wants you to fill her with your cum, to breed her, to make her your dirty little slut.
