I'm so glad my boyfriend is home. I'm feeling so horny, and I've missed him all day. I start talking dirty to him, getting him turned on. I love getting him rock hard talking when I talk about him pleasing this pussy. I start rubbing my tits and rubbing his cock at the same time. He loves when I do that. I tell him about how I've been thinking about that big fat cock of his deep inside my wet pussy. I tease him for a while to get him nice and turned on, playing with my body to get him nice and hard. Once he is bulging out of his pants, I pull his cock out and slide it into my mouth. I get it nice and wet, talking dirty to him, telling him how I love sucking his nice fat cock. I slurp up on down on his cock, getting it nice and wet. I can tell how much he is getting into it. I love seeing the look on his face as I please him, then I hear him call me... step-Mommy? Yeah, I definitely heard him say "suck it step-Mommy." What was that? He confesses that he has a step-Mommy fetish? Wow, I guess I didn't expect to hear that, let alone while I am in the middle of sucking on his cock. Well, I guess I can give it a try for him... So I guess I just say things like, "Do you like it when ... step-Mommy sucks your cock?" He does. Ooh I like that reaction. I'll try a different one. "Do you like this step-Mommy mouth sucking on your cock?" He does. "Do you like step-Mommy pleasing you, taking every inch down that throat?" I really like turning him on like this. I keep milking that cock with my mouth and giving him all the dirty step-Mommy talk I can think of. Next I climb on top of him. As I straddle his cock, I ask if he wants this wet step-mommy pussy. His twitching cock tells me that he does. Fuck I can't believe how wet I am doing this. I didn't expect to start getting this turned on. I tell him he is step-Mommy's bad boy as I rub his cock on my wetness. As I slide his big cock inside of me, I tell him to stretch that step-Mommy pussy, and wetness leaks out of me all over his cock. Fuck this cock is too big for this step-Mommy pussy. He bends me over the bed and starts taking me from behind. I tell him to step-Mommy wants him to play with that asshole as he fuck me. He pounds my pussy with his cock, and tI tell him to push that finger into step-Mommy's ass. He fucks me harder until he's about ready to cum, then he flips me onto my back. I confess to him that I can't believe how much this is turning me on. I tell him to be a good boy for step-Mommy and give it to me. He has step-Mommy's juices dripping down his cock as he stretches me so much. Such a big boy for step-Mommy. As he slows down, I realize he wants to cum on step-Mommy's face, dripping down my chin. I get on my hands and knees and start sucking his cock again. I tell him how I love tasting that step-Mommy pussy juice all over his cock. I keep telling him to cum for his step-Mommy until he loses control and shoots the biggest load I've ever see him cum. He unloads all over step-Mommy's face. His cum drips back down his cock, and I put my mouth back on him, sucking both of our juices off of his cock. This is was surprisingly fun. We might have to do this more often.
