**Title: Late Night Confessions with Gemma**

I never thought my step-sister Gemma would be this bold. Ever since Mom married her dad, we’ve danced around each other—flirty glances, accidental brushes that lingered too long. She’s this tiny brunette with a wicked smirk, barely five feet of trouble in a tight little tank top. But tonight? Tonight, she crossed the line.

I was half-asleep when I heard the creak of my bedroom door. The dim glow of my phone screen showed Gemma padding in, wearing nothing but a thin white cami and panties that barely covered her ass.

“You awake?” she whispered, biting her lip.

I pretended to stir, playing dumb. “Gem? What’s up?”

She didn’t answer. Instead, she climbed into my bed, her hip pressing against mine. The warmth of her body radiated through my sheets, and I could smell her—musky, ripe, like she’d been rubbing herself all night. Fuck, was she wet already?

“I couldn’t sleep,” she murmured, her fingers tracing circles on my bare chest. Her nails dragged down, teasing, and I felt my cock twitch under the covers.

“Gemma…” I warned, but she just smirked and slid her hand lower, cupping me through my boxers.

“Mmm, you’re hard for me,” she purred, squeezing lightly. “You like me in your bed?”

I groaned, my hips bucking into her touch. “You know I do.”

She giggled, then rolled onto her side, pressing her ass back against me. I could feel the damp heat of her panties through my boxers, the fabric soaked with her arousal. She ground against me, slow and deliberate, making my cock throb.

“I’ve been thinking about you all day,” she admitted, her voice breathy. “Rubbing myself in my room, imagining it was your hand.”

Fuck. My fingers dug into her hip, pulling her tighter against me. I could smell her cunt now—musky, sweet, fucking intoxicating. My dick ached, begging to be inside her.

“Show me,” I growled.

Gemma bit her lip, then reached down, hooking her fingers into her panties. She dragged them to the side, and the scent hit me full force—her pussy was glistening, swollen, begging to be touched. She moaned as my fingers found her clit, circling it slow and firm.

“God, you’re so fucking wet,” I muttered, grinding my cock against her ass.

She arched against me, her breath coming in sharp gasps. “I—I kept thinking about you smelling me,” she admitted, cheeks flushing. “I didn’t shower after my run earlier… wanted you to know how bad I wanted you.”

Christ. I buried my face in her neck, inhaling her sweat, her arousal. My fingers slid lower, pushing into her tight little hole, and she whimpered, hips jerking.

“Fuck me,” she begged, grinding back onto my hand. “Please, I need your cock.”

I didn’t hesitate. I yanked my boxers down, my dick springing free, thick and aching. Gemma reached back, guiding me to her entrance, and I groaned as her hot, wet pussy swallowed me inch by inch.

“Oh fuck,” she moaned, her walls clamping down on me. “You feel so good.”

I gripped her hip, pulling her onto me with every thrust. The sound of our skin slapping filled the room, her moans getting louder, needier. She was so fucking tight, so warm, her cunt gripping me like she never wanted me to leave.

“You like how I smell?” she panted, looking back at me with hooded eyes.

“Fuck yes,” I growled, slamming into her harder. “I love your dirty little pussy.”

Her back arched, her fingers digging into the sheets as she came, her body shaking around me. I followed soon after, burying myself deep as I filled her, my hips jerking uncontrollably.

We collapsed together, breathless, sticky, and too fucking satisfied to care about boundaries anymore. Gemma turned, pressing her lips to mine in a lazy, possessive kiss.

“I’m keeping these panties,” she whispered, tugging the damp fabric back into place with a smirk. “Next time, I’ll let you taste them.”

Fuck. I was already hard again.
