The music throbbed, a dull bassline vibrating through the floorboards. I knew I shouldn't be here, especially not like this. But the way he looked at me, all raw need… I couldn’t stop myself.
Liam, my step-sister, was always off-limits. Her fiery red hair, those bright green eyes, that bubble butt that drove me crazy... But with Mom and Dad throwing this party, the house filled with chattering voices and the clinking of glasses, the risk made it even hotter. She had been doing a sloppy blowjob downstairs with me during the party, but the temptation was too strong to stop there.
He’d cornered me in his bedroom, a nervous laugh escaping my lips. "Liam, the guests…" I'd started, but he cut me off with a kiss, urgent and demanding. It wasn't the gentle, hesitant kisses we'd shared before. This was different, desperate.
He lifted my summer dress. My shaved pussy throbbed in anticipation. I wore a Cup B size bra, and he knew I was always shy about my small breasts. "You are sexy. I wish you would know it" he whispered against my ear.
He pushed me onto the bed, his eyes dark with desire. The muffled sounds of the party seemed to fade as he entered me, slow and deliberate at first, then faster, harder. Each thrust was a rebellion, a whispered secret in the cacophony of forced cheer downstairs.
I gripped the sheets, my nails digging in. The climax hit me like a tidal wave. A moan escaped my lips, and I bit down hard on my arm, praying no one heard.
He didn't stop. He surged forward one last time, filling me with his cum. The feeling of him inside me, warm and throbbing, was intoxicating. I came again, my body shaking.
Afterward, we lay tangled together, the silence thick with unspoken words. The party raged on downstairs, oblivious to our little rebellion. Was this a one-time thing? Or was this just the beginning? My natural tits pressed against his chest, making me blush. His piercings glinted in the dim light, reminding me of how close we were to being discovered.
We'd crossed a line, and there was no going back.
