Family Secret. I Play with my Stepdad's Horny Cock

Imagine your stepdad, a hot, horny man in his 40s, who can't keep his hands off your tight little 18-year-old body. He's been eyeing you from the moment you moved in, but you've always kept your distance, until now. You're sitting on the couch, watching TV, and he comes up behind you, his hard cock pressing against your back. You feel his warm breath on your neck as he whispers in your ear, "You know, I've always wondered what it'd be like to have you, just like family." Your heart races as you feel his hand sneak up your dress, rubbing your wet pussy through your panties. You turn around, your eyes meeting his, and you know you can't resist any longer. You reach down and unzip his pants, his hard cock springing out. "Is this what you want?" you ask, a naughty smile on your face. He nods, and you take his cock in your hand, slowly stroking it, feeling the heat of his desire. He groans, and you know you're in control now. You move down, taking his cock in your mouth, feeling it throb as you suck and lick. He reaches down, his fingers rubbing your clit through your panties, making you moan. You know you're playing with fire, but you can't stop. He pulls you up, his hands on your ass, and you wrap your legs around him, his cock pressing against your wet pussy. You feel his hard cock inside you, filling you completely. You can't believe you're doing this, but it feels so good. You start to move, your body grinding against his, your tits bouncing. He grabs your hips, his thrusts getting harder and faster. You can feel his cock hitting that sweet spot inside you, making you moan and scream. You know you're not going to last long, and you can tell he's close too. You can feel his cock throbbing, about to explode. You pull him closer, feeling his hot cum filling you up. You collapse onto the couch, your body shaking with pleasure. You know you've just crossed a line, but you can't bring yourself to regret it.
