You arrive home for the day and hear a noise in the kitchen, you take a look and see your step-mom being fucked by your step-uncle! You can't help but stand and watch for a while, taking your phone out and taking a few pics that you can definitely use as evidence in the future...
Your step-mom thinks she hears you arrives home and comes out to greet you, looking very guilty of something, with her bra sticking out and hair a mess, she over explains what you're step-uncle is doing there.
Later that day you find your step-mom in the living room relaxing and watching TV, you tell her you need to talk, and show her the photos on your phone. She goes into panic mode, denying the photos are even her, blaming your step-father for not satisfying her needs; every excuse in the book. You tell her the only way you will keep quiet is if she lets you fuck her too, she is appalled at first and can't believe her own step-son would come up with such a suggestion. After some back and forth, you take your cock out and she gives you a hand job and blow job. You then fuck her on the couch in
missionary followed by her riding you in
cowgirl and you making her orgasm. You then
blow your load inside of her, which you really shouldn't have!

Some time passes and at first your step-mom was mad at you, but she couldn't help but keep wanting more. Fast forward a couple of months and now you are the one having an affair with her, rather than your step-uncle. You both look forward to the times your step-dad is out of the house and you can really enjoy each other. You eat her pussy before she rides you in reverse cowgirl and cowgirl, finishing off looking deep into her eyes in missionary as you give her another huge creampie.
