**Title: A Sibling Secret**

The air in my bedroom was thick with sweat and something else—something raw and electric. My stepsister, Lily, stood in front of me, her fingers already tugging at the hem of her tiny sleep shirt. She had been teasing me all night—brushing against me in the hallway, bending over just a little too far when she grabbed something from the fridge—and now here we were, locked in my room, both knowing exactly where this was going.

I was already hard, my cock stiff against my boxers, aching for her. Lily smirked, biting her lip as she peeled off her shirt, letting it drop to the floor. Her tits were perfect—perky, with dark pink nipples that hardened under my stare.

“You like what you see, stepbro?” she asked, her voice dripping with mischief.

“Fuck yeah,” I growled, reaching out to palm her tits. She moaned as I pinched her nipples, rolling them between my fingers until she was breathing hard.

Lily reached for my waistband, yanking my boxers down in one swift move. My dick sprang free, thick and throbbing. She licked her lips before sinking to her knees, her fingers wrapping around my shaft.

“You’re so fucking big,” she whispered before taking me into her mouth.

I groaned as her lips slid down my cock, her tongue swirling around the head before she took me deeper, gagging slightly before pulling back, spit dripping down her chin.

“Fuck, Lils,” I hissed, grabbing a fistful of her hair. “Just like that.”

She sucked me harder, bobbing her head fast, her hand working the base in rhythm with her mouth. I could feel my balls tightening, but I wanted more.

I pulled her up, shoving her onto my bed. She giggled as I yanked her panties off, spreading her legs wide. Her pussy was already glistening, her pink lips swollen and wet.

“You’re fucking soaked,” I muttered, rubbing my thumb over her clit. She gasped, bucking her hips.

“Please, stepbro,” she whined. “Fuck me already.”

I didn’t need to be told twice. I lined up my cock and pushed inside her in one rough thrust. She cried out, her nails digging into my back as her tight cunt stretched around me.

“Shit, you feel amazing,” I groaned, pulling back before slamming into her again.

Lily wrapped her legs around my waist, urging me deeper. “Harder,” she panted. “Fucking wreck me.”

I obeyed, pounding into her, the sound of our skin slapping filling the room. Her tits bounced with every thrust, her moans growing louder, more desperate.

Then she did something I didn’t expect—she reached between us, rubbing her clit furiously as I fucked her, her eyes locked on mine.

“I—I’m gonna piss,” she whispered, her voice shaking.

I didn’t stop. “Do it,” I growled.

Her breath hitched, and then warmth spread between us as she let go, her piss soaking my cock and thighs, dripping onto the sheets beneath us. The sensation made her pussy clench tighter around me, pushing me closer to the edge.

“Fuck, that’s so hot,” I moaned, slamming into her harder.

Lily came with a wild scream, her body trembling as I kept thrusting, chasing my own release.

“I’m gonna cum,” I warned.

“Inside me,” she begged.

I buried myself deep as my cock pulsed, filling her up until I was completely spent.

We collapsed together, sticky and breathless. Lily smirked up at me, her fingers tracing lazy circles on my chest.

“Best. Stepsibling. Ever.”
