Nearly Caught Fooling Around With Step-Auntie At Party

My step-nephew has turned into quite the man. I love this little game we play, I enjoy constantly teasing him with those skin tight outfits and lingerie I flaunt in a bid to drive him crazy. It's worth the effort as it seems to work like a charm as he can't take his eyes off me whenever I'm around how could he possibly resist a hot MILF. I attend our step-families masquerade party dressed to the nines in a sexy dress, stockings & lingerie underneath with satin opera gloves and that's when I decide to make my move. Throughout the event, I have my eye on my step-nephew showing off my long legs and bending over just enough to show off a little bit of my ass to tease him even more. I know he's finding it hard to resist me now I can tell, I approach him we chat briefly before he whisks me away to an empty room with nobody else in sight. I like that how he just took charge, I strip out of my dress to reveal my sexy lingerie set underneath and now he can't take it anymore and wants to show me what he can really do. I never knew he had such a big cock, I jerk and suck that huge dick enjoying teasing him getting it sloppy telling him how naughty it is that we snuck away just so he could have his way with me. Laying back on the bed now to fuck me, full on missionary sex I can't remember the last time I had cock this good! This is so wrong but we just keep going imagine if we ever got caught in the act, I'm about to cum but then I hear a knock at the door quickly he pulls out as we hide. It's his step-sis coming to look for him. Our absence from the party didn't go unoticed as I hang my head out of the door to make small talk to her. But he can't help himself fucking his step-aunt even though his step-sis is on the other side of the door. I try to contain my moans as he continues to pound me. I imagine to get rid of her just long enough until I finally let myself cum. That was a close call, but still even after that we just keep fucking. It's worth the risk as my step-nephews cock just feels so damn good and I mount him again to ride him. I tell him we need to be more careful and not get caught but he doesn't seem to care if everyone knew we were fucking. I feel myself getting close again and this time I want him to cum inside me. We finish together moaning my head off and I hope nobody heard that given how loud we just were. How naughty would it will be to go back to the party and talk to the entire step-family with my step-nephews cum dripping out of my pussy, and how they’ll never know what just happened. I haven’t had sex that good in years, but he has a lot to learn and I'm certainly going to enjoy teaching him a few tips and tricks to make him even better. We better get back out there, but I can’t wait till next time.
