"Haruna. I’ve been messaging you for hours. You haven’t replied."
Her tone wasn’t just impatient—it was accusatory, possessive, the kind of voice that made Haruna’s spine lock up, her breath hitching as if she’d been caught with her fingers buried inside herself. Her body tensed beneath me, her thighs trembling as my cock—thick, heavy, veins throbbing—pressed against her dripping, swollen pussy, the tip already slick with her arousal.
"S-Sister..." Haruna whimpered, her voice cracking as she tried to shift away, her hand flying down to cover herself. Too late. Her fingers trembled against her glistening, puffy lips, her pussy dripping with juice, desperate to be filled. "I-I was... with Aunt Julie and... and Jack—"
I growled, my grip snapping around her wrist like a vice, yanking her hand away. The head of my cock dragged up her slit, parting her folds, grinding against her clit in slow, deliberate circles.
Haruna’s back arched, a broken, needy moan tearing from her throat—"Aaaah—! N-Nnngh...!"—her juices gushing, coating my shaft in hot, sticky proof of how badly she wanted this.
Yuko’s voice tightened, suspicion bleeding into every syllable. "Haruna... what the hell is happening over there?"
Haruna bit her lip so hard it should’ve bled, her face flaming crimson, her thighs shaking as she fought to keep her voice steady.
"I-It’s nothing, Sister! I’m just—hng—helping Hannah clean her—ah!—her room—!" Her words shattered as I pressed the thick crown of my cock against her entrance, not pushing in—just teasing, just promising—making her pussy flutter, her hips jerk helplessly toward me.
Yuko scoffed, her disdain dripping through the speaker like poison. "You must help Hananh... she has done so much for you.."
Haruna said, " Hmm...Sister.. "
The sound of her nails tapping against something—impatient, predatory. "Is Aunt Julie still angry at you?"
Haruna’s eyes widened in silent terror, her head shaking frantically at me—don’t, don’t, don’t—but her body betrayed her, her hips rolling into the pressure, her pussy weeping, begging to be stuffed full. "N-No, Sister... she swallowed hard, her voice cracking under the strain. "A-Aunt forgave us..."
Yuko hummed, slightly mollified, but the edge in her voice never faded. "Good. ...Oh." Another beat. Then, colder. "Where’s Jack?"
Haruna’s smirk was instant, victorious—she knew if I took that phone, my cock wouldn’t be burying itself inside her anytime soon. "S-Sister, Jack’s right here..." She shoved the phone into my hand, her fingers lingering just a second too long, brushing against mine. "You wanna talk to him?"
I took the phone, pressing it firmly against Haruna’s stomach, my other hand sliding up her thigh, my thumb circling her clit in slow, maddening strokes. My voice was low, amused, and dangerous.
"Sister Yuko..." I purred, dragging out her name like a caress. "Did you miss me already?"
Yuko’s voice turned to venom. "Miss you? Don’t flatter yourself."
I looked down at Haruna, her cheeks flushed, her lips parted, her breath coming in ragged little gasps as my thumb pressed harder, making her whimper. She mouthed ’fuck you’ at me, but her eyes were begging.
I waited.
Then—
With a slow, brutal push, I breached her entrance.
Haruna’s mouth fell open, a shattered, obscene moan ripping from her throat—"AaaaaAAAH—! F-FUCK—!"—her back arching off the bed, her pussy stretching, clamping down around the thick intrusion, her walls fluttering as I sank deeper, deeper—
I slammed my hand over her mouth, muffling her screams, but the wet, desperate sounds still leaked out, high and needy, her tongue flicking against my palm as she choked on her own pleasure.
Yuko’s voice sharpened. "What the hell was that?!"
I didn’t skip a beat, my voice smooth, mocking. "Oh, that? Hannah found a stray cat. Sounds like it’s starving for milk."
From the side, Hannah giggled, then let out a perfect, teasing mewl. "Meee~ow..."
Yuko sighed, annoyed but buying it. "Ugh. Yeah, sounds hungry."
I chuckled darkly, my hips rolling just enough to make Haruna’s eyes roll back, her nails digging into my arm. Not the cat, sister.
"I’ll talk to you later, Yuko," I murmured, my voice rough with restraint. "Got to feed this thing first."
Yuko hesitated, then—"Fine. But send Haruna back before dark."
I grinned, feral. "Wouldn’t dream of keeping her."
I hung up.
And then—
I fucked her sister raw.
The Punishment
The second the call ended, Haruna let out a sobbing, relieved moan, her pussy clenching around me like she’d been waiting her whole life for this. "F-Finally—! Ah—! J-Jack, you bastard—!"
I didn’t give her time to breathe.
I slammed into her, bottoming out in one brutal thrust, my balls slapping against her ass, my cock stretching her to the limit. Haruna screamed, her back arching, her tits bouncing, her fingers clawing at the sheets. "NGH—! TOO—! TOO MUCH—!"
"Too much?" I growled, pulling out until just the tip remained, then plowing back in, harder. "Or not enough?"
"I-I—! AH—! I HATE YOU—!" she sobbed, but her legs locked around my waist, her heels digging into my back, forcing me deeper.
I leaned down, my lips brushing her ear, my breath hot. "Liar." My hand snaked between us, my fingers finding her clit, rubbing in tight, punishing circles. "You love this. You love it when I fuck you like a slut while your sister listens."
Haruna whimpered, her face burning, but her pussy gushed, soaking my cock, her walls fluttering around me. "N-No...! I-I don’t—! AH—! F-Fuck—!"
I chuckled, thrusting deeper, hitting that spot that made her see stars. "Then why are you dripping for me?" I pulled out, slapped my cock against her pussy, then rammed back in, making her scream. "Why does your tight little cunt keep milking me like it’s starved for my cum?"
"I—! I—!SHUT UP—!"* She tried to push me away, but her hands ended up gripping my shoulders, her nails digging in as she pulled me closer, her body betraying her with every desperate, needy roll of her hips.
I grabbed her throat, not tight enough to choke, just enough to make her feel it, to remind her who was in control. "Say it."
"N-Never—!"
I pounded into her, harder, faster, my balls drawing up, my cock swelling—"Say. It."
Haruna’s eyes rolled back, her mouth falling open, her orgasm crashing over her—"I—I’M A SLUT—! I’M YOUR FUCKING SLUT—!"
That was all I needed.
With a guttural groan, I buried myself to the hilt, my cock pulsing as I filled her, jet after jet of hot, thick cum flooding her pussy, marking her, claiming her—
Haruna screamed, her body convulsing, her pussy clenching, milking every last drop from me as her own orgasm wrecked her, her juices mixing with my cum, dripping down her thighs—
I collapsed on top of her, breathing hard, my cock still twitching inside her.
Haruna panted, her body trembling, her voice weak. "...We’re so fucked if Sister Yuko finds out."
I grinned, rolling off her, my cum already leaking from her well-used pussy.
"Oh, she will." I traced a finger through the mess between her legs, then pushed it into her mouth, making her suck it clean. "And when she does..." I leaned in, my lips brushing hers. "We’ll make sure she watches next time."
