The house was a summer rental in the Hamptons, paid for by our parents’ joint account, filled with the kind of forced family fun that made me want to drown myself in the ocean. But the pool—an infinity edge that seemed to drop into the Atlantic—was the one thing that made the trip bearable.
Until she turned it into a weapon.
Peyton was my stepsister. Twenty-five, a competitive swimmer, with a body that looked like it had been carved by water itself. She’d been avoiding me since the spring, since the night at her apartment when we’d shared too much wine and she’d kissed me against her kitchen counter, her hands in my hair, her mouth tasting like merlot and regret.
We hadn’t spoken of it. Hadn’t texted. Hadn’t made eye contact across the dinner table until tonight, when she’d suggested a night swim and our parents had said “what a great idea for bonding.”
Now it was 10 PM. The pool was lit from below, turning the water turquoise and the night into something unreal. Our parents—her father, my mother—were on the patio twenty feet away, drinking Sauvignon Blanc and laughing about stock portfolios or whatever married couples talked about after three glasses.
I was underwater. Holding my breath. Counting to thirty because Peyton had dared me, because I was competitive, because I needed to prove something.
When I opened my eyes at twenty-seven, she was reaching down from above, her hand extended through the surface, her face illuminated by the pool lights like some kind of water deity come to claim me. She grabbed my wrist and pulled.
I surfaced, gasping. Peyton was right there, holding the pool edge, her wet blonde hair plastered to her neck, her black bikini top clinging to her skin in a way that made me forget how to breathe.
“Your parents are on the patio,” I whispered, water streaming down my face, my heart hammering. “They can see the pool. They can see us.”
Peyton just smiled. That slow, dangerous smile that had been haunting me since the kitchen counter. She took a deep breath. And she dove under, pulling me down with her into the blue.
Underwater, the world ceased to exist. Sound disappeared—no parental laughter, no clinking glasses, no crickets. Just the blue glow, the rising bubbles, and Peyton’s face inches from mine. Her hand found my waist, pulled me against her, and her mouth pressed against mine in a kiss that tasted like chlorine and rebellion and every secret I’d been keeping since spring.
Her other hand found my bikini bottom. Slid under the elastic. Found me wet—and not from the pool.
I gasped. Bubbles escaped my mouth, rising toward the surface like silver prayers. Peyton’s fingers pressed inside me, moving with a rhythm that was slow and devastating and completely silent. She used the water as cover, as camouflage, as the perfect alibi for what she was doing to me while our parents drank wine twenty feet away.
She pulled me toward the deep end. The pool wall. A shadowed corner where the lights didn’t reach and the infinity edge made it look like we were falling into the ocean. She pressed me against the tile, her body covering mine, her fingers moving faster, deeper, her free hand gripping the pool edge above my head.
I needed to breathe. My lungs were burning. But Peyton didn’t let me surface. She just held me there, suspended between air and water, pleasure and panic, her eyes locked on mine in the blue light.
She made me come underwater. The orgasm was strange, muted, completely consuming—my body shaking, bubbles breaking from my lips, my scream lost in the chlorine and the silence. She held me through it, her fingers still moving, drawing out every wave until I was limp and floating and completely dependent on her to pull me back to the surface.
She did. We broke through together, gasping, our foreheads touching, our bodies hidden by the pool’s edge from the patio’s view.
“Girls?” My mother’s voice. “Want some wine? We’re opening another bottle.”
” We’re fine!” I called back, my voice high, strange, completely unlike my own. “Just swimming!”
“Okay, honey! Don’t stay in too long!”
Peyton didn’t let go. Her hand was still inside my bikini bottom, her thumb circling my clit, her mouth on my ear.
“Again,” she whispered. “I want to feel you come apart underwater one more time before we go inside.”
We stayed in the pool until midnight. She made me come three more times—against the pool wall, on the steps where the water was shallow, and finally in the pool house at 2 AM, where she’d dragged me after our parents went to bed, where the smell of chlorine mixed with the smell of us, where she showed me that water wasn’t the only thing that could drown me.
I still can’t swim laps without thinking of her. Every pool, every beach, every bath—her name is there, underwater, silent, completely mine.
