**Beach House Secrets**

The summer air was thick with salt and sweat, the kind that sticks to your skin and makes everything feel sticky and slow. My sister and I had the beach house to ourselves—mom and dad were away on their anniversary trip, and my sister had just turned twenty-one. She’d been flirting with me all summer, little glances, little touches, always lingering when she didn’t need to. Tonight, though, it was different.

We’d been drinking on the deck, the ocean roaring in the distance, the sky a deep, endless blue. She was wearing this tiny white bikini, the kind that made it impossible to look away. I’d caught her looking at me too, her eyes dipping down to my shorts more than once.

“You’re staring,” she said, smirking as she took a sip of her drink.

“Yeah, well, you’re making it hard not to.”

She laughed, low and knowing, then stretched out on the lounge chair beside me. The way her hips shifted made the fabric of her bikini bottoms ride up, just enough to give me a glimpse of the soft, pink skin beneath. My dick was already stiff in my shorts, and when she noticed, she didn’t look away.

“Someone’s excited,” she murmured, her fingers tracing lazy circles on her thigh.

I swallowed. “You know what you’re doing.”

She just smiled, slow and wicked, then hooked a finger under the waistband of her bikini bottom, tugging it just enough to make my breath catch. “Maybe I do.”

That was it. I reached out, grabbing her wrist, pulling her onto my lap. She gasped, her ass pressing right against my hard cock, and fuck, the heat of her through the thin fabric was incredible.

“You’ve been teasing me all summer,” I growled, my hand sliding up her thigh, under the edge of her bottoms. She was already wet, her pussy slick and warm against my fingers.

“Yeah,” she breathed, grinding down against me. “And now you’re gonna do something about it.”

I didn’t waste time. I yanked her bikini to the side, my fingers spreading her folds, rubbing her clit in fast, tight circles. She moaned, loud and shameless, her nails digging into my shoulders. “Fuck, yes, right there—”

I pushed two fingers inside her, feeling her cunt clamp down around me, so fucking tight. She rocked against my hand, her hips jerking, her tits bouncing with every movement. I could feel her getting closer, her moans turning desperate.

“I wanna see you cum,” I said, twisting my fingers inside her.

She came with a sharp cry, her whole body trembling, her pussy pulsing around my fingers. But I wasn’t done. I pulled my hand free, her juices glistening on my skin, then grabbed her by the waist and flipped her onto the lounge.

She was still panting when I yanked her bikini bottoms down just enough to expose her pussy, pink and swollen. My cock was throbbing, leaking pre-cum, and I couldn’t wait any longer. I stroked myself a few times, then aimed right for her wet cunt, sliding inside in one smooth thrust.

“Oh my god,” she gasped, her back arching. I fucked her hard, deep, her tight heat squeezing me perfectly. Every thrust made her whimper, her nails clawing at the fabric beneath her.

“You like that?” I grunted, slamming into her. “Like your brother’s dick in your pussy?”

“Yes, fuck, yes—”

I could feel my balls tightening, my orgasm building fast. I reached down, rubbing her clit again, and she came instantly, her cunt clenching around my cock like a vice. That was enough to push me over the edge.

“Gonna cum,” I groaned, pulling out at the last second. I jerked myself off fast, my cock pulsing as thick ropes of cum splashed across her bikini bottoms, still clinging to her hips. White streaks painted the fabric, dripping down onto her skin.

She whimpered, watching as I covered her, her fingers brushing through the mess. “Fuck,” she breathed.

I collapsed beside her, both of us panting, the sound of the ocean mixing with our ragged breaths. She turned her head, grinning at me.

“We should do this again.”

Yeah. We fucking should.
