Step-mom caught by step-son

Your out and you come home earlier then expected and see your step-mom cheating on your step-dad with the neighbor. You confront her and she ends up confessing that while step-dad thinks she’s his perfect trophy wife she’s actually a total slut. She’s been with not just the neighbor but also her boss, husbands friends, etc. She loves taking risks and almost getting caught and experiencing new cocks. She needs you to keep her secret and she’s seen you checking her out before so she offers you whatever you want to not tell your step-dad. She lets you first touch her body, starting with her tits, but she knows you loves her ass, and once she has you hard she takes you in her mouth loving sucking you off. She tells you that you mustn’t leave any evidence and makes a show of swallowing it all licking you clean. Step-dad will be home any minute but your still hard, normally guys are finished after she does her thing, and she needs more and asks if you want to fuck her. Rubbing you against her she slips the tip in but warns you have to be careful as she doesn’t have a condom, she makes everyone wear one as she’s not on birth control, but your bare cock feels amazing. As they go she dirty talks about how risky this is as she can feel you leaking precum already and she super fertile but how much she’s missed feeling bare cock and how much better it is. Asking where you want to cum you say you want to fill her and impregnate her
