family barbecue turned into me moaning on her cousins cock

I never thought the dirtiest sex of my life would happen at a boring family barbecue. My best friend had dragged me along to her place since her parents were throwing one of those big backyard get-togethers. Music, beer, kids running around, old people gossiping, nothing I was excited about.

Then he showed up. Her older cousin, mid twenties, tall, lean but muscular, sun-kissed skin with tattoos peeking from under his shirt. The type of guy you feel staring before you even look. And when I finally looked, he was already watching me back.

We barely talked at first, just casual bullshit while standing near the cooler. But every time he spoke, his voice dropped low, almost like he wanted me to feel it more than hear it. I laughed at something stupid and he leaned in close enough that his breath tickled my ear. My thighs pressed together before I even knew what I was doing.

As the night went on, the crowd got louder and drunker, but he kept finding excuses to stand near me. Reaching over my shoulder for a drink, brushing past me in the kitchen, letting his hand linger on my lower back just a little too long when he moved by. Every little touch was a spark that had me wet before I admitted it to myself.

When it finally happened, it felt almost inevitable. He whispered that he wanted to show me something in the garage. I followed without even thinking. The second the door shut behind us, he pressed me against the wall, kissing me hard. My towel-sized sundress slid up around my hips in seconds, and his hand was between my thighs, finding just how soaked I was through my panties.

"Fuck," he muttered, "you wanted this as bad as I did."

I didn't even try to deny it. I just spread my legs wider and let him slide my panties to the side. His cock was thick and throbbing, and I was dripping before he even pushed in. When he did, my whole body arched off the wall, the stretch burning and perfect at the same time.

He fucked me like he'd been waiting for this all night, one hand gripping my ass hard, the other over my mouth to muffle my moans so the whole damn family wouldn't hear. Every thrust slammed me deeper into the wall, and all I could think about was how wrong it was and how good it felt.

"Say you're mine," he growled against my ear, pumping into me harder.

I was whimpering, pussy clenching so tight around him I thought I might lose it. "I'm yours," I gasped, barely able to breathe.

The orgasm ripped through me before I even realized it was coming, my legs trembling so hard he had to hold me up. He fucked me straight through it, relentless, until he spilled inside me with a groan so deep it vibrated through my chest.

When I finally stumbled out of that garage, my panties were soaked and his cum was still dripping down my thighs. And the dirtiest part? I couldn't stop grinning.
