I got a new motorcycle, and I can't wait to show it to my StepMommy. Just the thought of her straddling it makes my cock twitch in my pants. She's never ridden a motorcycle before and acts adorably intimidated by it. I convince her to go ahead and sit on it. I can't help but be a little envious of the bike, wishing it was me that she was going to sit on top of like that. She looks at me playfully and asks, "Do you think I could be a hot StepMom?" All I can think about it is her gorgeous mouth, and how badly I want to feel it wrapped around my cock, which is already straining against my pants. She notices the growing bulge and starts to ask me about my boner. I can't hold back anymore. I'm going to do it. I pull my cock out, savoring the look of shock on her face. I quickly pull her head closer to me though she starts to protest. As soon as she opens her mouth, I push my rock hard cock into her open mouth, thrusting over and over into her warm, wet mouth. I can't believe I'm actually mouth fucking my own StepMommy. I think she is slowly giving in to realizing that she wants this too. She's not pushing back as hard as she was. Finally having my StepMommy sucking my cock is overwhelming me, and I pull out just in time to shoot my cum all over her beautiful face and titties. Looking at her covered in the mess I just made all over her, I instantly get hard again.I'm going to break in this bike by giving my StepMommy a ride she'll never forget. I rub my cock against her pussy. It's already so wet, telling me she wants this much more than she pretends not to. My cock throbbing with anticipation, I slide it inside of StepMommy and the sound of her gasping at my size sends a wave of pleasure washing over my body. As she is bent over my bike, I thrust deeper and deeper inside of her. Though she tells me to stop, she keeps bouncing harder and harder against me with her juicy ass, taking every inch of my thickness inside of her pussy. Soon, she covers her mouth and cums on me, her juices dripping down my shaft and covering my balls. Her excuses get weaker now, like "Stop or the neighbors might hear us!" as if that even get me to slow down. She unbuttons her dress and slowly takes it off while I'm still inside of her, telling me what she really wants me to do. I'm getting close and I thrust inside of her with the frenzy of finally getting to fuck my StepMommy like I've wanted to for so long. I erupt, shooting every ounce of cum I have deep into her soaking wet pussy. She pulls my cock out, mixing our juices as they drip out of her pussy. I can't believe StepMommy's first ride on a motorcycle was while riding my cock. Let's hope it won't be the last.
