Doufám, že si to můj nevlastní syn zítra nevzpomene

Hearing a knock at the door late at night I wonder who it could possibly be. It's my stepson. He reeks. He had attended a party and apparently had too much fun. Well, I guess I need to help him to bed. Since my bedroom is downstairs and the closest I take him there and help him up on my bed. While undressing him I can't help but notice the bulge in his underwear. I peek. Even soft his cock is huge. I know that I shouldn't but I'm getting so turned on that I can't help myself. I stroke on it a bit. He moans and stirs but doesn't wake up. I begin to suck on it. Finally unable to control myself any longer I undress and straddle his big cock. I ride it until I feel him shoot a nice big warm load of cum up into my pussy. Uh - oh. Hopefully he won't remember any of this tomorrow. And hopefully I won't have some explaining to do in 9 months (Solo simulated with dildo)
