Your step sister has noticed you've been going to the gym, and says you're looking good. She start's flirting with you & removing her clothes, saying there is nothing wrong with two people wanting pleasure. She sucks your cock before riding it cowgirl & reverse cowgirl, She tells you not to cum in her as she isnt on birth control, but you can't help yourself, your sisters pussy feels so good and you spunk in her. Oops, what will you guys do?
