You have invited your sister over for the long weekend and tonight is the last night that she is there. You have already fucked her once but this time she wants you to make her pregnant. She wakes you up on the couch noticing that you are hard and entices you first with her mouth talking about wanting you to shoot your load into her. She then leads you to the bedroom where she strips and plays with herself before riding your cock. She tells you that she wants you to impregnate her this time for real and she wants every last drop of cum inside of her pussy. So you give her a creampie making your sister pregnant
