I Watch the Cup Final with my Stepsister and I end up Fucking her and Showing who the Champion Is.

Watching the cup final with my stepsister, it was just like any other day until it wasn't. We were both glued to the TV, cheering for our teams, but as the match got intense, something else started to heat up between us. She was in my lap, her big ass grinding against me, her big tits pressing against my chest. I couldn't help but get hard, and she felt it. I could see her eyes flicker with desire, and before I knew it, her hand was on my cock, stroking me through my pants.

She leaned in, whispering, 'You know what I think? I think we should make our own championship.' I smiled, pushing her hair back from her face, 'And how do you propose we do that?' Her response was a slow, seductive grin.

She stood up, turned around, and dropped to her knees. I was already hard, but watching her big ass sway as she crawled towards me made me even harder. She unzipped my pants and pulled out my cock, her eyes widening at the sight of it. 'Oh, baby,' she murmured, 'you're so big.' And then she took me in her mouth, swallowing me whole.

I groaned, my hands fisting in her hair. She sucked and gagged, her big tits bouncing as she moved her head back and forth. I couldn't take it anymore. I pulled her up, spun her around, and bent her over the couch. She was wearing a tiny skirt, so I just pushed it up and pulled down her panties. Her ass was a masterpiece, big and round, just like her tits.

I rubbed my cock against her wet pussy, teasing her. She moaned, pushing back against me. 'Fuck me,' she begged. And so I did. I slammed into her, her tight pussy gripping me like a vice. She screamed, her big ass shaking as I pounded into her.

She was so wet, so fucking hot. I could feel her getting ready to cum, her pussy clenching around me. I reached around, my fingers finding her clit. She came with a scream, her pussy milking my cock. I couldn't hold back anymore. I pulled out, my cock throbbing, and came all over her back and ass.

She collapsed on the couch, her breath coming in little gasps. I couldn't stop looking at her big ass, her big tits, her big Latina curves. She looked up at me, a satisfied smile on her face. 'You win,' she said, 'you're the champion.' And I knew she was right. I had won, just not in the way I thought I would when I started watching the cup final with my stepsister."
