My step-son walks into my room, and he can tell that I'm upset. I found out today that his step-father has been cheating on me. It's been going on for some time now. So merlot, because it helps. I know my step-son is old enough to understand, but I don't want him to worry about it. I just can't believe his step-father would do this. Part of me wants to get revenge. I know it's not very tasteful, but part of me wants to cheat on him and give him a taste of his own medicine. my step-son likes that idea? No, I shouldn't be entertaining that kind of behavior. Yes, his step-father cheated first, but I don't even know who I would cheat on him with. Well... I think I must have had too much. I can't believe my step-son would even suggest that I cheat on his step-father with him! It is completely inappropriate! First, I am way too old for my step-son. More importantly, I'm his step-mother! No, I've had way too much merlot. We shouldn't even be having this conversation. Yes, I plan on having sex with somebody else, but not my step-son! But the way he is looking at me like that... I should stop right now! It's making me have inappropriate thoughts about my step-son. He grabs me and pulls me close to him. I shouldn't be enjoying this, but it feels so nice to be close to him. I love to be touched and to be wanted again. I can't help it, and I lean in to passionately kiss my step-son. What am I doing?! I pull away and tell him to leave. But my step-son starts taking his pants off! He is so hard! I tell him to stop teasing me with that cock! Maybe if I just touch his cock a little bit. It feels so good in my hands! This is wrong on so many levels, and it's making me so wet... Fuck it. I can't hold back anymore. I need to feel my step-son. I stroke his cock and passionately kiss him. This needs to stay our secret. I get down on my knees and pull out my step-son's cock. It's so perfect, I can't help but put it in my mouth. He is so nice and hard for his step-mommy. I pull his cock out of my mouth and stroke it while he shoots so much cum all over step-Mommy's big, fat titties. I put his cock back in my mouth and suck that cum off of his yummy cock. I want more from him. I slip out of my clothes, teasing my step-son by rubbing his cum all over my titties. I tell my step-son that I'm all ready to finally get revenge on that cheating bastard of a step-father. I climb on top of my step-son and slowly push his huge cock inside of me. It barely fits! It takes a minute to get used to his massive cock stretching out step-Mommy's pussy. I tell him to fuck me harder until I cum all over his cock, my tight, wet pussy pulsing around that throbbing cock of his. I'm going to make him cum for me again. I pin him down and fuck him hard until he is just about to cum. I pull his cock out at the last minute, as he shoot so much cum for his step-mommy all over my titties, which are still covered in his cum from earlier. I lay down next to my step-son, still drenched in his cum. I feel so good that I finally got back at his step-father. It's time for a nap now. The next day, I am avoiding my step-son, needing some time to process what has happened. That night my step-son finds me and merlot by the fireplace again. I tell him that I'm disappointed in myself for doing what we did yesterday. I'm his step-mother, and some things you just can't come back from. We can never let that happen again. Of course I liked it. That's the problem. I liked it too much. He's my step-son, and it's not okay. I can't be with him! Why doesn't he understand? What we did was wrong! My step-son doesn't listen and comes closer. No, I won't admit to him that I want to be with him. But I miss his lips already. I tell him to go, but he pulls me in close to him again. I tell him to stop, but I can't help kissing him deeply. I pull away, telling him we can't do this again! I know he can tell that I want to, even if I say I don't. I can't help but to pull down my top for him so he can look at step-Mommy's titties again. Why can't I stop myself? What it is he does to me? I sit back and pull up my loose sweater. I can't hold back anymore. I tell him to get over here and taste his step-mommy. I sit on his face. I know he as a great view of step-Mommy's titties while I ride his face and tell him to taste his step-mommy. My step-son makes me cum on his face. He is such a bad boy, and I like it. I make him unzip those pants and pull that cock out for me. I bend over the next to the fireplace and slide my step-son's giant cock inside of me. His cock feels even better than I remember as he fucks step-Mommy hard from behind. I tell him to keep fucking me harder until I cum even harder on my step-son's cock. I turn around so he can see step-Mommy's titties bouncing in his face. I slide back on top of his cock and ride him. He gets so deep! I want him to cum deep inside of me this time. I tell my step-son to cum with me. I can feel him shoot his cum deep inside of me as my wet pussy throbs all over his perfect cock. I confess to him that I did love it. He asks if I'm going to stop this. I don't think so. It's just too good. Plus, his step-father is not going to stop cheating.
