Chapter 173: Students Call Me What? (R18)

I didn’t ease them into it this time.

I stepped behind Yoona first, one hand wrapping tight around both of her black horns, the other gripping her hip hard enough to bruise.

The academy blazer was still on, shirt half-open, longer skirt folded high at her waist. I lined up and drove into her in one deep, relentless thrust. The wet, filthy sound of it filled the room as her pussy stretched around me again, still slick with my earlier cum.

Yoona’s moan ripped out of her, high and broken. "Ahh—Daddy—!"

I didn’t give her time to adjust. I fucked her hard and fast from the start, hips snapping forward so the desk creaked under every impact.

The fabric of her uniform shifted with each thrust, the blazer sliding, the white shirt pulling tight across her bouncing breasts, the folded skirt flapping against her lower back. I used her horns like handles, yanking her back onto my cock so she had no choice but to take every thick inch.

"Look at you," I growled, voice still locked in that stern professor tone. "My perfect student council president, bent over my desk in full uniform, taking Daddy’s cock like a desperate little slut. Thank me."

"Thank you—ahh—thank you, Daddy—thank you for fucking me—" Yoona’s voice cracked on every thrust, moans tumbling out of her in a steady, needy stream. "It’s so deep—Daddy’s cock is so deep—"

Beside her, Yerin was watching with glassy, hungry eyes, short pleated skirt still flipped up, panties stretched around her thighs. Val stood right behind the younger twin, two fingers buried inside her, pumping slowly while her other hand rubbed tight circles over Yerin’s clit.

"Don’t just watch," I ordered, never slowing my hips. "Kiss your sister. I want to see my naughty students making out while I use one of them."

Yerin didn’t hesitate. She leaned over, cupped Yoona’s flushed face, and crashed their mouths together. The kiss was messy and wet, tongues sliding, soft moans spilling between them every time I bottomed out in Yoona.

The sight of the two of them making out in their ruined academy uniforms while I fucked one of them sent a fresh pulse of heat straight through my cock.

Val’s free hand slid up under Yerin’s open shirt, pinching and rolling a stiff nipple. "Good girls," she murmured. "Keep kissing. Let Professor see how much you love each other while he ruins you."

I pulled almost all the way out of Yoona, then slammed back in hard enough to make her cry out into her sister’s mouth. The wet slap of skin on skin grew louder. Yoona’s horns were warm and smooth in my grip; every time I tugged them she clenched harder around me, a fresh gush of slick coating my cock.

"Switch," I said after a few more brutal thrusts.

I pulled out of Yoona with a wet sound. A thick strand of mixed cum and arousal stretched between us before breaking. Val immediately guided Yerin into place, hands flat on the desk, back arched, short skirt held high. I stepped behind her, gripped both of her hips, and buried myself to the hilt in one smooth stroke.

Yerin’s moan was louder than her sister’s. "Fuck—Daddy—!"

I started pounding her immediately, harder and faster than before. The short pleated skirt bounced wildly with every thrust. Her loose navy tie swung against the wood. I reached around, grabbed a fistful of her dark hair, and pulled her head back so she had to arch even deeper.

"Louder," I ordered. "I want the whole fucking academy to know how well my student takes cock, even if no one can hear it."

"Yes—ahh—yes, Daddy—your cock feels so good—thank you for fucking me—" Yerin’s words dissolved into high, broken moans. Every time I slammed home she pushed back to meet me, chasing the feeling.

Yoona, still dazed and dripping, turned her head and watched with dark, hungry eyes. I caught her gaze and jerked my chin. "Don’t just stare. Get under her. Suck your sister’s clit while Daddy fucks her. I want to feel you both at the same time."

Yoona dropped to her knees without a second of hesitation, sliding between Yerin’s spread thighs. The moment her mouth closed over her sister’s clit, Yerin’s entire body jerked. A sharp, startled cry tore out of her.

"Oh my god—Unnie—ahh—"

I felt it immediately, the way Yerin’s pussy fluttered and clenched around my cock every time Yoona’s tongue flicked or sucked. The dual sensation was filthy and perfect. I kept fucking her in deep, steady strokes while Yoona licked and sucked greedily underneath, her black horns brushing against my thighs.

Val stood behind Yoona, one hand in the older twin’s hair, guiding her mouth, the other reaching up to squeeze and play with Yerin’s breasts through the open shirt.

The room filled with wet, obscene sounds, the slap of my hips against Yerin’s red ass, the soft filthy noises of Yoona’s mouth working her sister’s clit, the constant stream of moans and broken "Daddy"s spilling from both of them.

I switched again without warning, pulling out of Yerin and dragging Yoona back up by her horns. I bent her over the desk once more and slammed back into her from behind. Yerin, still shaking, dropped to her knees this time and crawled under her sister, returning the favor, tongue sliding over Yoona’s stretched, dripping entrance right where my cock was thrusting in and out.

The feeling of Yerin’s tongue licking around my shaft and Yoona’s clit at the same time almost made me lose it. I groaned, gripping Yoona’s horns tighter and fucking her even harder.

"That’s it," I growled. "Lick your sister’s pussy while Daddy fills it. Good fucking students."

Yoona was beyond coherent sentences now, just high, continuous moans and the occasional broken "Daddy—yes—please—" every time I bottomed out. Yerin’s tongue never stopped, tasting both of us, moaning into her sister’s cunt.

I made them switch places again and again. One bent over the desk taking my cock, the other on her knees licking and sucking wherever she could reach. Val kept both of them stimulated, fingers, mouth, hands on their breasts, never letting either of them come down fully.

The uniforms stayed on the entire time, growing more wrinkled, more stained, more perfect with every passing minute.

When I finally felt both of them getting close again, I pulled Yoona up so her back was against my chest, still buried deep inside her, and reached around to rub her clit in tight, fast circles. Yerin stood in front of her sister, kissing her deeply, one hand between Yoona’s legs to help, the other pinching and rolling her own nipple.

"Cum for me," I ordered against Yoona’s ear, voice rough. "Both of you. Right now. Show Daddy how good his students can be."

Yoona broke first, clenching hard around my cock, a long, broken wail of "Daddy—" tearing out of her as she came. The rhythmic pulsing of her pussy dragged me right to the edge. I fucked her through it, then shoved her forward onto the desk and buried myself in Yerin instead, pounding the younger twin through her own orgasm until she was sobbing with overstimulation and still begging for more.

I lasted maybe ten more thrusts before I buried myself to the hilt in Yerin and came hard, flooding her with thick pulses while she clenched and moaned around me. When I finally pulled out, both of them were trembling, thighs shiny, uniforms completely wrecked, my cum leaking from both of them and dripping onto the desk and floor.

They stayed bent over exactly as ordered, panting, faces flushed, lips swollen from kissing each other.

I ran a hand over both of their glowing, spanked asses, feeling the heat still radiating from the earlier punishment.

"Detention’s still not over," I said, already hardening again at the sight of them. "You’re going to clean each other up with your tongues. Then you’re going to get back into position so Daddy can fuck you again. Uniforms stay on. Roleplay stays on. Understand?"

"Yes, Daddy," they answered together, voices hoarse and eager.

Val smiled faintly, already stepping in to guide their heads between each other’s thighs.

The next round started the moment their tongues touched skin again, wet, filthy, and nowhere near finished.
