Day 3. University. Evening.
When the last bell rang, Takashi stood up without even glancing in my direction. As he passed my desk, he carelessly left a small folded note on it and walked out of the classroom.
I unfolded the paper.
“Building B, fourth floor, the room at the very end of the corridor past the men’s restroom. We’re waiting. In twenty minutes. Don’t be late.”
I carefully folded the note and put it in my pocket. I stood up slowly. The back of my skirt felt heavy and wet; the fabric clung unpleasantly to my skin. The vibrator inside continued to hum quietly and insistently. My hips were slick with moisture. My socks and shoes still bore the dried traces of semen.
Inside—there was nothing sharp. Only the same quiet melancholy. The classroom gradually emptied. I moved slowly on purpose, gathering my notebooks and pen, even though everything was already packed. When I finally raised my head, only the three of us remained: me, Ayaka, and Naomi, a girl from the parallel class where Takashi studied.
Ayaka came up to me, looking worried.
“Mika ... wait. What’s going on with you? You’ve been ... not yourself for days. Pale, quiet ... And today Minami was calling you a ‘yujo’ in the hallway and laughing. What happened? Please, tell me. We’re friends.”
I stood, staring at the floor. The vibrator inside continued its quiet work, making my muscles twitch involuntarily. Between my legs, it was hot and wet. Every movement sent an unpleasant, slick sensation through me.
“It’s personal, “ I whispered, not lifting my eyes.
Ayaka stepped closer.
“But Minami ... she says things like that ... I don’t understand. You can trust me. If someone’s hurting you... ”
I finally looked up. Ayaka’s eyes were full of genuine concern. For a moment, it almost hurt. But I only shook my head slightly.
“You decide for yourself who I really am, Ayaka.”
Naomi, who had been silently gathering her things by the window the whole time, shot me a quick glance and turned away.
I grabbed my backpack, slung it over my shoulder, and headed for the door. Ayaka stayed standing in the middle of the classroom. I could feel her gaze on my back, but I didn’t turn around.
The corridor was almost empty. I walked slowly. Every step sent a faint tremor through my legs—the vibrator continued to work, refusing to let me forget my state. I reached the stairs, took a deep breath as if making a choice that didn’t really exist, and started climbing to the fourth floor.
Each step felt heavier than the last. My heart beat steadily, but heavily. I knew what awaited me there. I knew exactly who would be in that room. I knew resisting was already pointless.
On the third floor, I paused for a moment, placing my hand on the railing. The vibrator inside suddenly intensified—apparently, someone was already controlling it remotely, hinting that I should hurry. I exhaled quietly, feeling my body betray me with warmth low in my abdomen.
“Let it ... be what it will be,” I thought, detached.
I continued climbing to the fourth floor.
I continued climbing to the fourth floor. My legs felt heavy, as if filled with lead. Each step on the stairs sent a faint tremor through my knees. The vibrator inside me didn’t stop — it no longer just hummed, but pressed insistently against the most sensitive spot, making the muscles in my lower abdomen twitch periodically. Without panties, I could feel every drop of moisture slowly sliding down the inner sides of my thighs. The skin there was hot and sticky. My skirt barely covered my bare body, and that sensation made me feel even more exposed than if I were completely naked.
The corridor was empty and silent. Only my footsteps and the quiet hum of the vibrator inside me. My heart beat steadily, but heavily, as if someone had placed a stone on my chest. There was almost no fear. Only that same thick, viscous melancholy and a resigned acceptance of my fate.
I reached the end of the corridor. The door past the men’s restroom was slightly ajar. Muffled voices and soft laughter came from inside.
I paused for a moment, placing my hand on the cold handle. A brief thought flickered in my mind: “This is it. It starts now.”
I turned the handle and stepped in.
There were five people in the room.
Takashi was sitting on the edge of the teacher’s desk, calmly looking at his phone. Next to him stood three of his friends — the same ones I had performed oral on in the restroom during the previous class. One of them, tall with a short haircut, was holding Minami, pressing her back against his chest. His hand had slipped completely under Minami’s unbuttoned blazer and blouse, clearly groping her breast. Minami giggled quietly, pressing against him, whispering something in his ear as if it were perfectly normal.
The moment I entered, all five turned their heads at once.
Takashi slowly lifted his gaze. A calm, almost satisfied smile appeared on his lips.
“You’re here. Good.”
He nodded toward the door.
“Lock it.”
I turned silently, closed the door, and turned the key. The click sounded loud and final. The sound made something inside me clench — not fear, just a heavy realization: there was no way out.
Takashi turned on music on his phone — a quiet, rhythmic track with heavy bass. The sound filled the room, bouncing off the walls.
“Now, stand in the middle and start undressing. While dancing, “ he said calmly, almost gently. “This is just to make it more interesting... ”
He took a small remote and pressed a button.
The vibrator inside me instantly went to maximum. The strong, sharp vibration hit my clitoris and deeper. My legs buckled immediately. I exhaled quietly through my teeth. Everything inside clenched sharply, then relaxed, and a new wave of hot moisture flowed down my thighs. My breathing faltered. I felt my nipples harden instantly under my blouse, and the lower part of my abdomen fill with a heavy, pulsing heat.
“After you finish undressing — crawl to us, “ Takashi continued, keeping his gaze fixed on me. “Crawl. Understand?”
I stood in the middle of the room under the eyes of five people. Minami looked at me with a faint, satisfied smile, still pressed against the hand of the guy groping her under her blouse. Takashi’s three friends watched me silently, with predatory interest. The vibrator mercilessly hummed at maximum. I took a step forward, into the center of the room.
“No...” — the old voice whispered inside me. “Not here ... Not in front of them...”
But my body no longer listened. My hips began moving slowly to the rhythm of the music. I raised my hands and started undressing while dancing — awkwardly, mechanically, but still dancing.
First, the blouse. I unbuttoned it, one button at a time, feeling the fabric slide off my shoulders. My breasts, in a white bra, were now fully exposed to their eyes. My nipples were hard, painfully sensitive. When the blouse fell to the floor, I heard Minami’s quiet giggle.
“This isn’t me... — the thought struggled in my mind. It’s just a body. Just a reaction...”
The skirt. I slowly pulled it down, swaying my hips. The cold air of the room touched my wet, heated crotch. I could feel all five of them watching — eyes fixed on my glistening folds and the thin stream of moisture slowly running down the inside of my left thigh.
The bra. Click. My breasts fell heavily outward. My nipples were dark and swollen. I kept moving — slowly circling my hips, raising my hands, letting them trace over my own body. It all looked pathetic and humiliating, but I couldn’t stop.
The vibrator inside suddenly intensified even more. A sharp, deep wave shot from my clitoris to the very bottom of my abdomen. My legs buckled.
“No ... not now ... not in front of them...”
But my body no longer asked permission. The orgasm hit me suddenly, fiercely. I gasped and moaned loudly, my legs trembling and giving way. I fell to my knees, then onto all fours. Everything inside me contracted with long, powerful spasms. A hot stream of moisture spurted onto the floor — not just droplets, but a tiny fountain. I felt the puddle spreading beneath my knees.
My mind screamed: “Get up! Don’t show them this!”
But my body betrayed me, trembling and continuing to spasm, expelling wave after wave of liquid.
I breathed heavily, on all fours in the middle of the room. The floor beneath me was already wet. A thin, glistening trail stretched from my knees backward.
Takashi looked down at me with a faint smile.
“Crawl, “ he said calmly. “To us. Crawl.”
I slowly lowered myself onto my stomach. My breasts pressed against the cold linoleum. I began to crawl — slowly, humiliatingly. Every centimeter was a struggle. Between my legs, everything still pulsed and flowed. Behind me, a wet, shining trail marked my shame — a broad, treacherous stripe of my own moisture.
I crawled toward them. Naked. Shivering. Leaving behind a wet trail of my humiliation.
I stopped at Takashi’s feet and looked up. My hands were trembling as I reached for his trousers to undo the zipper.
Takashi shook his head calmly and pushed my hand aside.
“Not me, “ he said quietly. “Start with them. And her.”
He nodded toward his three friends and Minami.
I froze for a moment. The old voice inside me kept fighting: “No ... not like this ... don’t start yourself...”
But my body had already begun moving. I turned to the first guy — tall, short-haired. My hands reached for his belt. I unbuckled it, then the zipper. I pulled out his erection. Thick, heavy, with a large head and pronounced veins. Already fully hard. I took him into my mouth, slowly, deeply.
He grabbed my hair and pushed his hips forward, driving himself down my throat. I gurgled, my eyes watering instantly.
“Look at her go right away, “ he chuckled. “Kono kou benki... ”
The second guy standing nearby had already unzipped himself. His was longer, thinner, with a swollen head. I turned to him and took him in my mouth while the first continued holding my head. He didn’t just let me suck — he fucked my mouth hard, thrusting deep and sharply.
The third guy stood a little further, slowly stroking himself as he watched me from above.
“Yujo... “ he murmured. “Look at how wet she is. Wetter than in the bathroom.”
Minami stood nearby, holding her phone at face level, filming close-ups. She smiled.
I moved from one to the next. One allowed me to work on him myself — lips and tongue tracing every vein, taking him deep. Another fucked my throat harshly, holding my head and driving all the way in. Saliva ran down my chin, dripping onto my chest and the floor. The vibrator inside me didn’t stop, and with every thrust into my mouth, a new wave of heat built in my lower abdomen. The third, with the longest but thinnest shaft, first let me suck, then penetrated deep, moving inside me, making me gasp for air.
“This isn’t me...” I kept repeating to myself. “I’m just ... doing. I’m no longer human...”
But my body betrayed me. Every time another cock went deep into my throat, my vagina tightened around the vibrator, and a fresh hot stream flowed onto the floor.
Minami leaned closer, filming how the saliva stretched from my lips to the head.
“Deeper, Mika. Show them what a good mouth you are.”
I paid no attention. I let them do whatever they wanted with me.
Only one thought kept spinning in my mind over and over:
“I crawl. Then I suck. And I keep flowing ... And I don’t even try to stop this humiliation. As if this is how it’s supposed to be.”
After a while, the guys started coming.
The first grabbed my hair with both hands, thrusting deep into my throat. I felt him pulse hard, hot, thick streams hitting my throat. I swallowed quickly, mechanically, trying not to choke. The taste was bitter and salty. He held me until the last drop, then slowly withdrew and wiped himself on my cheek.
“Good kou benki... “ he murmured, stepping back.
The second was rough too. He first fucked my mouth hard and fast. When he came, the semen was so thick I barely managed to swallow it all. Some dripped from the corner of my mouth, running down my chin. He didn’t let me wipe — just slapped my lips with himself and stepped away.
The third came more quietly. Holding my head, he moved slowly and moaned softly. When he spilled, I swallowed everything without flinching. My throat was already warm and sticky.
I breathed heavily, saliva and cum running down my chin onto my chest. My whole face was wet. I slowly turned toward Takashi, still on all fours, when suddenly Minami’s sharp heel struck me hard in the side, right under the ribs.
The pain was sharp, like an electric shock. I flinched, arched, and let out a quiet moan, pressing my hand to the sore spot. The wind was knocked out of me for a moment.
“Hey, mecu, “ Minami purred sweetly but venomously. “You forgot about me. You owe me too.”
