**Playing with Fire**

It started as a stupid dare. My twin sister, Naruko, and I were lounging around our house, bored out of our minds. The AC was broken, and the summer heat was unbearable. We were already in tank tops and shorts, but even that felt like too much.

“You know what would be cooler?” Naruko smirked, stretching lazily on the couch. “No clothes at all.”

I rolled my eyes. “Yeah, right. Like you’d actually do that.”

She raised an eyebrow—that same fucking *challenge* look she always gave me. “What, scared?”

Hell no I wasn’t scared. Before I could second-guess it, I yanked my shirt off. “Your turn.”

Naruko bit her lip, then—without hesitation—peeled off her tank top. No bra. Her tits bounced free, pink nipples already stiff from the rush of doing something so reckless. My dick twitched in my shorts before I could stop it.

“Pants too,” she dared, fingers hooked in her waistband.

Fuck it. We’d seen each other naked as kids all the time. This shouldn’t be weird. I shoved my shorts and boxers down in one go, my cock springing up, already half-hard. Naruko’s eyes locked onto it, but she didn’t back down—just shimmied out of her shorts and panties until she was just as bare as me.

We stood there for a second, completely naked, the air between us thick. Then Naruko smirked. “Still think you can beat me at video games like this?”

“Easily,” I shot back, but my voice came out rougher than I meant.

We sat down on the couch, controllers in hand, but I could barely focus. Every time she shifted, her tits swayed, or I caught a glimpse of her smooth pussy pressed against the cushion. My cock was fully hard now, throbbing against my thigh.

Naruko *noticed*. Of course she did.

She dropped the controller. “You’re distracted.”

“Am not.” My jaw clenched.

She leaned into my space, her tits brushing my arm. “Liar.” Then her hand slid over my thigh, fingers tracing up to my cock. I groaned as she wrapped her fingers around me, her grip warm and tight. “You’re *so* hard.”

“Fuck, Naruko—”

She wasn’t stopping. Her thumb swiped over my leaking tip, smearing precum, and I grabbed her wrist. “We shouldn’t—”

“Who cares?” she breathed, her other hand cupping her own pussy, fingers slipping easily between her folds. “I’m already wet. You wanna feel?”

I did. *Fuck*, I did.

I pulled her onto my lap, her slick cunt grinding against my cock. She gasped, her nails digging into my shoulders as she rolled her hips, coating my shaft in her wetness. “You—you’re so big,” she panted, her breath hot against my neck.

My hands gripped her ass, spreading her open as I dragged my cock up and down her slit. “Tell me you want it.”

“I want it!” Her back arched, pressing her tits against my chest. “Put it in, *please*—”

I didn’t make her beg twice. I lined myself up and shoved deep, her tight pussy clamping around me in one slick, hot squeeze. Naruko *shrieked*, her nails raking down my back as she took every inch. “Oh fuck, oh *fuck*—”

I fucked up into her hard, her tits bouncing with every thrust. She was so goddamn tight, so wet, her moans loud and desperate. “You feel *so good*,” I growled, slamming her down harder.

Naruko’s head fell back as she rode me, her pussy sucking me in deeper. “I’m gonna cum—”

“Then cum,” I snarled, pinching her clit.

She *screamed*, her cunt pulsing around my cock in hot, rhythmic waves. The second she came, I lost it—pounding into her one last time before my cock twitched and I emptied myself deep inside her, groaning her name like a prayer.

We collapsed together, panting, still locked tight.

Naruko giggled against my shoulder. “Best game ever.”

I smacked her ass. “Rematch?”

She grinned. “Only if we stay naked.”
