It has been so dry lately, and I ask my step-son to put some lotion on my back. Such a good step-son, he does spread it all over like I need it. He tells me that he likes me dress too. Oh, something keeps poking me. Oh, is that ... is that my step-son's boner? I mean, he was practically humping me with it. Hmm, well if he wants to keep poking step-Mommy with it, I guess that's okay. He can just keep putting lotion on step-Mommy's back, and I'll let him go ahead and push his boner against step-Mommy's ass. His hands feel good rubbing on my back, and his cock is so hard rubbing into me. It's okay. I tell my step-son it' makes sense he would have these kind of feelings for me. I've taken care of him his whole life. When he tells me he likes looking at me, I tell him that's completely normal. He tells me he's been looking up things online about a word that is a special kind of love between a step-mother and step-son. I know what he means. And as his step-mother, it is my job to take care of all of my step-son's needs and be a safe place to unleash whatever fantasies he may have. Now, about this hard cock of his... he is so hard right now as I rub my hand against him in his pants. I definitely need to take care of my step-son. I get down on my knees and pull that rock hard cock out of his pants. Oh, it's so perfect! I start asking my step-son about these special things he's been looking up online. Are they like the things I'm doing to him right now? They are. Good. I'm glad that I can be a safe place for him to explore these feelings and fantasies. I wrap my cock around his mouth, getting it nice and wet. I ask him if he likes step-Mommy sucking on his cock. Yes, he does, and he wants me to keep going. Now I don't hold back and suck his cock the way he fantasizes about and deserves. I remind him that he feels so good in step-Mommy's mouth. All of a sudden, with no warning, he cums all over my face! That was clearly an accidental cum. I guess all that talk reminding him that his step-Mommy was sucking his cock was enough to send him over the edge way too fast. That's okay, I let him have this moment and get that cum all over step-Mommy's face and mouth. I suck on his cock some more, tasting his lovely cum. I guess we should just clean up now, right. Oh, he says he wasn't done, there are more things he wanted to do? He wants to see more of step-Mommy. I understand that. step-Mommy can show him if that's what he wants. With his cum still dripping off my chin, I stand up against the wall and start taking down dress. I let my step-son get a good look of step-Mommy and tell him to suck on my titties. He loves on my titties for a good while, then he tells me he's been thinking about step-Mommy's pussy and wants to get closer. He asks if I'm mad. No, I'm not mad. I just wish he had told me sooner. He's been fantasizing about step-Mommy's pussy for so long. I put him on his knees rubbing my pussy in his face. Sucking on that cock of his really made me wet. He wants to taste step-Mommy, so I let him bury his face in my pussy. He loves the way step-Mommy tastes, and his tongue feels so good. Well we've come this far, we might as well finish. I can't believe I'm about to have sex with my step-son. But step-Mommy's pussy is nice and wet, ready for my step-son's cock. He slides that perfect cock against my soaking pussy lips, spreading his juices all over himself. He slides inside of me, and I can't believe this is actually finally happening. I'm so glad that I can bring my step-son's fantasies to life. He feels incredible inside of me. He gets to see his fantasies come true, and who knew my step-son could feel this good. He fucks me so good against the wall, and I want all I can get from him. step-Mommy is close to cumming, and I want him to cum with me. I want him to cum inside of me. What a good step-son he is, and I tell him to fill up step-Mommy's pussy with all that cum built up inside, fantasizing about step-Mommy. He let loose another huge load of cum inside of me. I can't believe how much cum I can actually feel filling me up. As he pulls his cock out, there is so much cum that it drips out of my soaking pussy all over his cock and the floor. I wish he had told me about these fantasies a long time ago so we could have been doing this so much more. But now we do have a lot more to look forward to.
