Becoming the Student's Cumdump
Song Jiwon had parted ways with him only minutes ago.
Min-gyu descended from the rooftop in silence, yet his mind was flooded with her lingering image. The way she crossed her legs, subtly exposing her thighs while smiling. Even the gesture of raising a finger to her lips and slowly tracing her tongue between them.
"She's insane. That was basically an invitation to fuck."
Min-gyu realized it clearly as he walked down the stairs. Song Jiwon was no longer an autonomous person. She had become a complete bitch who moved solely according to her master's orders.
More precisely, she was the kind of woman who would do anything if commanded.
Min-gyu found himself smiling. The corner of his mouth slowly lifted, and excitement once again boiled up from deep in his chest.
The moment he closed the front door behind him, the remaining heat in his body erupted. Without even setting down his bag, he headed straight to his room, sat at his desk, opened his laptop, and logged into his anonymous account.
BitchMaster69
One name floated above the chat window.
HornyBitchTeacher
Min-gyu began typing.
"I've given you quite a bit of freedom lately, bitch. You waited like a good little slut. Now that it's been a while, your master is going to give you an order."
The moment the Telegram notification chimed, Song Jiwon reflexively grabbed her phone from the bed.
BitchMaster69
Just seeing that name made her heart pound violently. Her face flushed, and her knees tingled. Staring at the screen, she bit her lip and started typing.
"Master…! I really missed you so much."
She had been behaving lately, but honestly… she had been bored. She had even talked to that student. He was so meek and obedient, hanging on her every word… and completely unable to talk back.
Song Jiwon hesitated for a moment, then deleted one of the sentences she had written.
("He's so cute that I actually started to feel a little affection for him.")
That sentence still felt like something she shouldn't say.
"This is our chance, Master. Make me even lewder. I'm completely ready. Please push me past the line this time."
Even after sending the message, she couldn't put her phone down. At this very moment, she had no idea that the person she was messaging was the very same student she had just been thinking was cute on the rooftop.
But Min-gyu knew. He knew exactly how foolishly, innocently, and obscenely she was becoming her master's bitch. And because he found it so endearing, he wanted to break her down even more thoroughly.
Min-gyu looked down at his phone and began typing again. The scene she had shown him on the rooftop refused to leave his mind. The way she had covered her lips with her index finger and teasingly flicked her tongue at him. It was an unmistakable fellatio gesture.
"If I don't raise the intensity of my commands after seeing that, I don't deserve to be her master."
"Tomorrow at school, make that student cum. In whatever way you want. In the way you've been dying to try. If I order you to 'make that guy cum,' what can you do?"
"I don't want to hear anything like 'That might be difficult.'"
"Tell me what you can do. You're a bitch, after all."
When Min-gyu's message arrived, Song Jiwon's fingertips trembled. But the trembling wasn't from fear—it was from excitement.
"…Make that student cum?"
She smiled quietly and began typing.
"With my hands… or my mouth, I think I could manage. Doing it at school is a bit risky, after all. Hehe. It's not like I couldn't do more, but if someone walked by it would be a problem, right?"
Min-gyu stared blankly at her reply for a moment. "So she's already assuming penetration is possible. She's only holding back because it's school…"
The thought sent a wave of heat rushing up the back of his neck. "…Seriously? She wants to do that with me?"
He closed his eyes. His mind was already burning red-hot.
"As expected, no one does it like a bitch. The fact that she's already thinking about shoving a cock in her mouth the moment she gets turned on means she's become a real whore."
Right after sending the message, Min-gyu covered his face with one hand. His insides were boiling like mad, but he had to stay outwardly calm.
A notification sounded immediately. A reply from Song Jiwon had arrived. When he checked his phone, her words appeared on the screen.
"Haaang… When Master talks to me like that… I want to act even more like a bitch…💦 But Master…? Me… servicing another man, sucking him, even making him cum… Doesn't that make you jealous…? I'm Master's bitch, after all… So instead of serving Master, I'm just offering myself to another man like a whore, right…?🥺💧"
Min-gyu laughed a beat late after reading it. If he had been serious, he might have felt jealous. But right now, she didn't know that the person she was asking this of was the very student whose precum was currently soaking his pants.
Min-gyu raised his fingers with practiced ease and slowly typed a humiliating reply.
"Jealous? That's something couples who date and love each other do. You belong to me. You're my property. How I use you is entirely up to me. Have you ever seen a hammer ask, 'Is it okay if I don't hit here?'"
Before he even read her next reply, Min-gyu was already certain. Song Jiwon had truly decided to become her master's tool. And soon her message appeared.
"As expected… it's you, Master. You're really on a completely different level from ordinary men… The way you treat me like a tool without the slightest hesitation. But I know. Inside that attitude…"
"…is your deep consideration, meant to turn me on even more…💖 Hehe… I'll do even better. Enough to make Master proud… I'll become even lewder and more devoted! Just trust me and give me orders!!"
In that moment, Min-gyu's gaze quietly changed. Beyond mere excitement, his eyes now held deeper plans and intent. He began preparing his next command, devising a new move.
Min-gyu closed his eyes and pressed his fingertips together again. His breathing was still uneven. His underwear was damp, and his cheeks were burning. Even so, he had to put on the mask of "Master" once more.
"When you arrive at school tomorrow, call that student somewhere you can have him alone. The staff room, an empty classroom… somewhere people won't pass by. You decide. I don't know your school."
"You said he's extremely passive and timid, right? If you can control a kid like that… what do you want to do to him?"
After sending the message, Min-gyu set his smartphone down. He ran his hand through his hair as if trying to tear it out.
"Ah… fuck… I hadn't thought this far ahead…! What do I do? How the hell am I supposed to make this real?!"
"…Haa… I really… don't know…!"
Until now, he had only been giving orders through text. But now he had to make her actually put her mouth on another man. She had said it was possible—had even said she wanted to try…
At that moment, another message arrived.
"Masteeer~🥺💕 Since Master gave me the big picture of making him cum… I'll do my absolute best!"
"Still… mmh… if you could just give me a little more detail… I'll try my very, very best💦"
Min-gyu looked down at his phone. There was the monster he had created, desperately waiting for instructions. He swallowed a short breath. The choice was now his. And soon, his fingers moved again.
"Fine. Making him cum is non-negotiable. When you see that student's cock right in front of you, if you feel overwhelming lust just from looking at it… I'll allow you to use your mouth."
"However, penetration—whether pussy or ass—is strictly forbidden. I don't want to let you be used that easily just yet."
"So when you're really about to lose your mind, use only your mouth. Got it? Just like a public urinal, receiving his cum instead of piss… only that much is allowed."
Min-gyu closed his eyes. Now it was time to imagine how Song Jiwon would go mad. She was no longer a person who made her own decisions. She was a thoroughly trained bitch who only moved when her master commanded. No—more precisely, she was "a woman who would do anything if ordered."
Min-gyu took a long breath. It was Song Jiwon's turn to respond. The woman who got so aroused just from the word "Master" — what kind of face would she make, what tone would she use, and how far would she claim she was willing to fall? Just imagining it made the cock in his pants slowly begin to twitch. Faintly, slowly, but unmistakably.
Min-gyu wanted to actually fuck her with his cock. Even after training her countless times, he had never once put it inside her. The fact suddenly tightened around his neck like an inferiority complex. But at the same time, his mind was tangled with sticky anxiety.
"What if I can't even get hard the first time?"
"I know where to put it, but actually doing it…? The flow? The timing?"
"Will I even be able to fuck her like a real man…?"
Until now, he had hidden his inexperience by pretending to give orders. He had trained her with a dominant tone, with his fingers, with text—without ever actually taking her.
"Only the mouth. No penetration allowed." That line wasn't for Song Jiwon. It was a cowardly defensive line Min-gyu had drawn to keep himself from breaking. And the thought of penetration still terrified him.
A notification sounded. Min-gyu felt a faint sweat on his fingertips as he slowly scrolled the screen.
"Yes… Master 💋 Just like you said, Master… if I really get turned on from the bottom of my heart…"
"I'm ready to accept that boy's thing. I'm just a toilet that moves according to Master's will. If that's what Master wants, I'll receive that student's cum like a toilet…"
Each word came out with a steady rhythm. Hesitation, anticipation, obedience, and beneath it all, the conviction of a bitch who was completely surrendering herself. Min-gyu stared at the message, unable to move a single finger, drinking in her words with his eyes.
She had truly reached that point. "If Master allows it, I will become a toilet that receives everything that comes out of a cock with my mouth." Even as she wrote those words herself, her face flushed while typing—it was so vivid he could picture it clearly even without seeing it.
And finally, Min-gyu placed his hand over the typing window. Even without opening his mouth or closing his eyes, her expression rose in his mind. Slightly parted lips, swallowing saliva, eyes looking up.
"I'm looking forward to the bitch's report tomorrow."
He sent the reply and ended the conversation.
