You are at a halloween party with your wife and her stepsister. You two have hooked up in the past, but you haven't seen her in years. When she runs into you, neither your wife or her husband are around, so you sneak off to the bathroom to reminisce on old times. Your wife doesn't like blowjobs, and her stepsister loves them. She kisses you and tells you how badly she wants you again, even know she knows her stepsis would freak. She doesn't care. No one will find out. Besides, you two hid a pregnancy from them, playing it off like it wasn't yours. That was years ago, but an accident, and now she doesn't want it to be an accident this time. Bending over the sink, she rips her fishnets and you finally fuck her raw again. She moans and grinds back on your cock, saying how much better she is, how she's the better stepsister. She loves you and your cock so much, she begs for you to fill her up and make her pregnant again, to homewreck without anyone finding out, cheating on your wife with her own stepsister. It's sick, but you love a little trick with a treat. This halloween gets messier than ever, and no one will ever find out.
