My Stepsister won't let me Finish a Video Game until I Fuck her first

Stealth mode activated as I sneak into my stepsister's room, ready to record a video game walkthrough. But hold up, she's not having it. She's got other plans, like making sure I don't finish gaming until I've given her what she wants. My heart races as she leans in, her breath hot on my ear, whispering her terms. It's a deal I can't refuse. Her hands roam over my body, her touch electrifying. I'm instantly hard, ready for whatever she's got in mind. She grins, knowing she's got me hooked. She wants me to fuck her, right there, right now. And I'm more than happy to oblige. We tumble onto the couch, her shirt off in an instant. Her perfect tits bounce as she straddles me, her wet pussy grinding against my jeans. I can't resist, I pull her down, my hands gripping her ass. She moans loudly, her head thrown back, as I grind back against her. We're both wild, both desperate. She slides off, unzips my pants, and takes my cock in her hand. She strokes it slowly, her eyes locked onto mine. 'You're gonna fuck me now,' she says, a wicked smile playing on her lips. I nod, unable to speak. She positions herself, her pussy hovering over my cock. She slides down, her pussy stretching around me. She rides me hard, her hips moving like a pro. I can feel her pussy clenching around me, her juices dripping down my shaft. She's so fucking wet. I grip her hips, pulling her down harder, faster. She moans, her pussy contracting around me. I can feel my orgasm building. She leans forward, her tits in my face. I suck on her nipples, my cock pounding into her. She comes, her body shaking, her pussy pulsing around me. I come too, my cock exploding inside her. She collapses on top of me, her body shaking with aftershocks. We're both exhausted, but satisfied. Mission accomplished. She's had her fun, and now it's my turn to finish my game. But for now, we're content to just lie here, our bodies entwined. This is what she wanted, and it's exactly what I needed."
