Slave Senior's Vigorous Masturbation
After lunch, each group was assigned rooms under their respective leaders. The gathering rooms and sleeping quarters were separate, of course—men and women couldn’t be put in the same room.
“Group 4, stay in this accommodation. Don’t go anywhere. Just rest until the program starts.”
After leading her group, Yoo Ra slipped straight into the empty room’s bathroom. It was originally reserved for the student council, but they were busy preparing the program and had left it vacant.
She opened her bag and looked at the items Jang Hansol had given her, calling them “gifts.” Lube, a dildo, and a silver plug that gleamed under the light. A small sticky note was attached to the lube, detailing exactly what she had to do.
“Giving me this crap as a present… haa… Jang Hansol’s actually insane.”
Everything about the items screamed their intended use. She had reflexively packed them after he said he wouldn’t fuck her again if she refused, but even after reading the instructions several times, she still worried whether she could actually go through with it while sane.
At the very end of the note, he had written in that infuriating way: “I’ll be checking, so do it properly.” Yoo Ra read the commands he had left her.
1. Wear only underwear for the entire MT. (You’re free to choose what.)
2. Wear the anal plug. (Use lube if it’s difficult to insert.)
3. Every day during the MT, record a video of yourself masturbating with the dildo and send it.
Every single one was the kind of order that would be disastrous if discovered. Especially during MT, when activity levels were high and the risk of getting caught was even greater.
‘Last time he made me go without panties at the bar… Is this bastard’s fetish completely broken?’
Grumbling, she lifted the toilet lid and sat down. Number 3 looked the simplest, so she figured she might as well get it over with now.
She kicked her pants off onto the floor and pulled her panties down to her knees. When she tore open the box, a thick, imposing dildo appeared.
Even when gripped with both hands, the head still stuck out. Its girth was so massive that her thumb and middle finger could barely touch when wrapped around it.
Feeling her throat tighten at the size—nearly identical to Jang Hansol’s—she took out the lube. She had no idea when someone might come into the bathroom. There was no time to properly loosen herself, so she squeezed out a generous amount and carefully coated both her pussy and the dildo.
She set her phone against the wall in video mode and fixed the dildo to the floor. Because it was so large, it stood upright on its own without any support.
‘What the hell am I doing in a bathroom…’
Self-loathing washed over her, but she had already finished preparing. Aligning herself, she slowly lowered her hips.
The moment she took it all the way in, her mind went blank. The heavy sensation of being completely filled made her head tilt back and her mouth fall open.
She came the instant it was inside. Her legs gave out and she nearly collapsed, but she barely managed to stay upright by bracing herself with her hands and feet.
‘Yeah… this weight… this feeling of filling me up completely…’
It couldn’t compare to when Jang Hansol fucked her himself. The warmth, the size, the speed at which arousal built—none of it matched. Still, for a dildo, it was satisfying enough.
‘Satisfying…? What am I even saying… I’m not doing this because I’m satisfied. I’m being forced to do this because of Jang Hansol…!’
Yet her body moved on its own, searching for the most sensitive spot as she began grinding against the dildo. Imagining it was Jang Hansol’s cock made her lose all control.
‘What do I do… my hips are moving on their own… I’m… I’m coming, coming, coming… I’m coming♥’
-Fshhhhh…!
She squirted, but the throbbing in her pussy still demanded more, so she immediately climbed back onto the dildo. Using the wet sounds of flesh slapping against silicone as fuel, she rubbed herself even faster.
Honestly, she couldn’t remember exactly how she had masturbated. All she knew was that she had done it with loud, shameless movements and positions.
Once she came back to her senses and stopped the recording, only a sigh escaped her lips. The bathroom floor was a mess, splashed with fluids from beneath the dildo. Because she had kept moving even while bent over, her breasts were pressed against the floor and marked red. Her ass stung from how hard she had slammed down.
“What the hell did I just do here… haa…”
Why couldn’t she ever refuse anything Jang Hansol said? Why did following his orders make her feel so exhilarated?
‘Have I really… become the sex slave he talked about?’
They had agreed the master-and-slave relationship would only exist in bed. Yet whenever he gave an order, she found herself thinking that even if she got caught doing something perverted and her normal life was destroyed, it would still be fine.
Obeying a man’s command to perform such an obscene act, getting so wet from it, and then personally recording and sending the evidence to him…
-Drip…
The woman who had just handed over a video that could ruin her life was getting turned on by it.
“Haa… I did it again… I shouldn’t be doing this…”
She was probably the only person in the world like this.
The senior who had shown them to their rooms, Yoo Ra, left in a hurry. Not long after, a video arrived from her via private message.
Lying on the bed in the empty room with earphones in, I immediately played the video.
‘She filmed it in the bathroom?’
Sound would echo quite a bit if she masturbated in there, so she must have found an empty accommodation.
She set the dildo—roughly the length of her face—down on the floor. Her face was on the smaller side, but I had prepared one as close to my own size as possible.
‘She’s taken something this big before, so she should be used to it.’
She swallowed hard while staring at the dildo, then slowly lowered her hips and rubbed the tip against her entrance.
[Hnnng… Jang Hansol, you crazy bastard… What am I supposed to do with something this big… hnn…]
She grumbled complaints about me while repeatedly pushing the large glans in and pulling it back out. Even though the size was familiar, inserting it all at once was still difficult, so she was warming herself up first.
But that only lasted a moment. With a determined expression, she dropped her hips and swallowed the dildo halfway.
[Haaah…! W-well, the size is similar, so… this much is…]
Her legs trembled as if she had lightly come. A thin trail of arousal slid down the shaft. Once the shaking subsided, she lowered herself again and took it all the way to the base in one go.
[Nngh…! Hiss… haah…]
Yoo Ra sat upright, convulsing. Once she adjusted to the size, she began doing slow squats. Every time she lifted her ass, the glans caught on her tight entrance and refused to slip out. When she dropped down, a wet, squelching sound echoed. She changed angles, searching for the spot that felt best, then started slamming down rhythmically once she found it.
[Hnn… hah… Jang Hansol…♥ hnn…♥ There… that feels good…♥]
She kept moaning my name even though I wasn’t there, completely absorbed in her own fantasy. It was obvious what she was imagining.
-Pop!
-Fshhhhh…!
She squirted the moment she pulled the dildo out. Most of it splashed onto the floor, but some of the powerful spray even reached the camera lens.
[Haaah… haah… More… this isn’t enough…]
Yoo Ra picked up the dildo and got into the rear-entry position I had taught her. Then, as if recreating the way I roughly fucked her, she grabbed the base herself and pounded her pussy at the same brutal pace I usually used.
[Ahnngh…♥ Master’s cock is poking my womb… it feels so good…♥]
Even while she was the one pressing the dildo in, she trembled her hips like she was delighted, stimulating her cervix. Her unfocused eyes and the drool spilling from her wide-open mouth made it clear she was lost in pleasure, no longer caring about the video.
She lowered her upper body to the floor and pulled the dildo out until it was barely inside, then slammed it back in with all her strength.
-Plap, plap, plap, plap…!
Having discovered a new way to feel good, she repeated the motion, chasing more pleasure. Every time her plump ass crashed down, it sent ripples through the flesh and made obscene sounds. Each thrust forced more of her juices out, soaking the floor.
[Nngh…♥ Ngh, ngh…♥ Hnnk…♥]
Her movements grew faster as she approached a bigger climax. Soon she let out beast-like moans and began shaking her hips violently.
[Hnn… hnnngh…! My slave pussy is… going… going…♥]
-Gush!
She tried to endure the pleasure by clenching her teeth, but eventually failed. A stream of yellow liquid began trickling out from below. Her eyes were completely unfocused, drool ran down her chin, and her massive breasts were squished sideways against the floor. Her hips trembled, her ass was raised high, and between her legs the yellow stream kept flowing. Even while orgasming, she continued slowly moving the dildo like something had broken inside her—nothing left but a female chasing pure instinctual pleasure.
Yoo Ra’s completely ruined appearance was captured in full on the video.
