**”Big Sister’s Gift”**
I never thought I’d get the balls to actually do it. My big sis, Theta—older than me by five years, curvy in all the right places, with a mouth that could make a priest sin—had always been off-limits. At least, that’s what I told myself. But ever since we moved back in together after her messy breakup, the tension had been unbearable. The way she walked around the house in tiny shorts and loose tank tops, no bra, her tits bouncing with every step. The way she’d stretch on the couch, arching her back, her tight pussy barely hidden under the fabric.
Tonight was different. We were alone, drinking wine on the couch, laughing about old times. The more we drank, the closer she got, her thigh pressing against mine, her fingers trailing up my arm.
“You’ve grown up so much,” she murmured, her dark eyes flicking down to my crotch before meeting mine again. My cock was already straining against my jeans.
“Theta…” I swallowed hard.
She smirked, sliding her hand onto my thigh. “You like what you see, little brother?”
Fuck, she knew. The way her fingers inched higher, teasing, until her palm pressed against the bulge in my pants. I groaned, my hips jerking up into her touch.
“I want you,” I admitted, voice rough.
Theta’s lips curled into a wicked grin. “Yeah? Show me.”
I didn’t hesitate. I grabbed the back of her neck and pulled her into a deep, hungry kiss. She moaned into my mouth, her tongue sliding against mine, her hands clawing at my shirt. I pushed her back onto the couch, grinding my hard cock against her thigh as I yanked her tank top down, freeing her tits. Her nipples were stiff, pebbled under my palms, and I sucked one into my mouth, biting just enough to make her gasp.
“Fuck, you’re so hard for me,” she panted, reaching down to unbutton my jeans. Her fingers wrapped around my cock, stroking me slowly as I shoved her shorts down, revealing her wet, glistening pussy. She was already dripping.
I pushed two fingers inside her, curling them against her tight walls, and she cried out, her hips bucking. “God, yes—you’re gonna make me cum already.”
“Not yet,” I growled, pulling my fingers out and shoving them into her mouth instead. She sucked them clean, eyes locked on mine, her tongue swirling around my digits.
Then I couldn’t wait anymore. I shoved her legs apart and buried my face between her thighs, licking a hot stripe up her soaked slit. Theta arched, her hands fisting in my hair as I sucked her clit, fucking her with my tongue. Her pussy clenched around nothing, juices coating my chin, and when I slid two fingers back inside, she came with a sharp scream, her body shaking under me.
But I wasn’t done. I needed to be inside her.
I sat up, my cock throbbing, pre-cum leaking from the tip. Theta reached for me, her fingers wrapping around my shaft as she guided me to her entrance. “Breed me, little brother,” she whispered.
That was all it took. I slammed into her, balls-deep in one thrust, her tight cunt squeezing me like a vice. Theta’s nails dug into my back as I fucked her hard, her tits bouncing with every snap of my hips. The wet slap of skin on skin filled the room, her moans turning into broken pleas.
“Cum in me—I want it, fill me up—”
I lost it. My balls tightened, and with a growl, I buried myself as deep as I could, pumping hot ropes of cum straight into her womb. Theta clenched around me, milking every last drop, her own orgasm wracking through her as she clung to me.
When I finally pulled out, my cum dripped from her stretched pussy, proof of what we’d done. Theta smirked, running her fingers through the mess before sucking them clean.
“Guess we’ll have to do that again soon,” she purred.
And I knew we would. Over and over until she was swollen with my kid.
