"Sex slave." She'd said it—clear as day.
Hmm. A full-on surrender, no less. And "use me however you want"? Perfect—100 out of 100.
"Beautiful, Sensei. You nailed it. Full marks this time."
"R-Really? Then don't ditch me—ever!"
"Of course not."
I'd only meant to reset our boundaries, but I'd leaned too hard into the threats. That edge dims her playful, eager charm—my bad. I'll dial it back next time.
"Sorry for being such a horny playboy. So… forgive me for fooling around with others, yeah?"
"I'd love to keep you to myself, but compared to this jackpot, I can deal. Might get jealous and petty sometimes—when I do…"
Her eyes gleamed with expectation.
"Oh, I'll make you feel good all night long."
"This can't be real. I'm not just passed out at my desk in the staff room, exhausted from overtime, right?"
"Want me to pinch you?"
"Yeah, hard… ow!? G-Gah, ahh!?"
"Whoops."
A wry grin—she'd offered her cheek, and I pinched it firm. She came instantly.
I'd forgotten her face was a live wire now. Mix that with her natural masochism, and it's chaos.
She clutched her pinched cheek, curling up, trembling like a leaf.
"My… my body… what's happening to it?"
She sensed the shift, unease creeping in. Time to dodge with momentum.
"Pain turns you on, huh? Perfect for my sex slave. So cute."
"W-Wait, this isn't right… hii, ahh!"
I licked her reddened cheek.
"Sensei."
"W-What…?"
"Round three—'Sensei' or 'Miyuki-san'? Your pick."
"…"
Our first night together—let's make it unforgettable.
Her eyes spun, but a tiny, strained voice slipped out.
"Use… Miyuki's body… however you want."
"Good girl, Miyuki-san. A treat for my obedient, one-and-only sex slave."
"Nn… nngh!"
I pecked her lips, nibbling softly, hands cradling her face—stroking her cheeks tenderly.
"Nn, nnh! …!"
The rush hit hard. Her eyes widened, locking onto my magic gaze up close.
Her body jolted—the fiercest quake yet.
"Uuuuh!"
"Whoa, already soaking the sheets?"
"…Ah… hah…"
She gushed, drenching everything, still spurting in little bursts.
"Miyuki-san. Miyuki-san?"
"Auh… ahh…"
Arms quaking, legs rigid—she kept climaxing, locked in place. Fucking hot.
"Might be too much to fuck her like this."
I slid a finger along her slick slit.
"Hiii!"
She arched, squeezing out the last of her flood, hips bucking wildly—pure provocation.
"Wow. Fucking you now might break you."
"N-No… not now… not now!"
She shoved at my chest, but her hands had no strength.
I grabbed them, pinning her down.
"Going in."
I forced her limp legs wide, pressing my cock against her.
"N-No! Aagh—guh!!"
One deep thrust—she peaked, eyes rolling back, spine bending like it'd snap. Her walls clamped tight, but her soaked heat begged for more.
"I'm moving now."
I ignored her, chasing my own pleasure, thrusting freely.
"Hii, hiii!"
She clawed at her hair, writhing under relentless waves, her thin chest heaving—pink nipples swollen red.
I flicked one with my finger.
"Fuh, guh!?"
Right, left, right, left—pinching, licking, toying with them however I pleased.
"Aah, aah!!"
At first, she screamed with each touch, but as I pounded her, shaking her limp frame, tears and drool smeared her face. Then, finally—
"—More."
That word lit my cock up before my brain caught on.
Deeper, harder—I ravaged her, unstoppable.
"Hii, haa! Aaaah! I'll lose it—I'll break!"
The more she suffered, the harder I got, digging in without mercy.
Wet slaps and squelching air drowned out her cries—she kept coming, spasms flaunting her wrecked body.
"Miyuki-san. Hold your legs."
She tried closing them after each peak, so I forced them wider, ordering her to grip them.
"Fuh… ha… like this?"
"Yes. Good girl."
M-shaped, spread bare—I loomed over her, stirring her insides with brutal thrusts. My fingers teased her wired lips—stroking, pinching.
"Auuu! Uuuuh! Mmph, nn!"
"Don't bite my fingers, okay?"
Was it cum or another gush? The sheets were warm and sopping—practically wringable.
Owning her like this, free to do whatever, no holding back—it's the best. Natsuki-san gets some care, but Miyuki? She's mine to command.
She can't say no, even at school. I won't risk exposure with reckless classroom play, but damn, the possibilities…
Imagining that, I sped up—fucking her harder, claiming every inch of her for myself.
