So Happy to Be Master's Cumdump Bitch
Slap! “Hikyaang♥” “Five minutes left. Hold on.” “Hagut♥ Heu…”
At the mention of five minutes remaining, Jisu let out a rough moan and began adjusting her posture. She seemed determined to endure just five more minutes, but her trembling legs made it clear her limit was fast approaching.
The fact that she had lasted this long was already remarkable progress. She had never managed to hold out for more than five minutes without cumming at least four times before.
“You’re holding out better than expected this time. Have you gotten a little used to the electric shocks?” “Hik… No way…” “Is that so? Then I’ll have to help you get used to them.”
When I raised the electric whip, she flinched and began to tremble violently.
“I-I don’t want… Hik! The electric shocks make everything tingle… My body feels weird…” “Really? You seemed to enjoy it quite a bit when you came.” “Hut… That’s because…”
She couldn’t say anything, as if I had struck a nerve. The electric shocks seemed to suit her surprisingly well; Jisu reacted more intensely than ever before, climaxing hard. So this was what it meant to enjoy something to death.
Of course, I had kept the voltage low enough that it wouldn’t actually hurt her, only serving as a trigger to heighten her pleasure.
Slap! “Hagiiit…♥” “Look at you. You’re loving it.” “Higiit♥ I’m cumming…♥ Huguuuung♥”
Her intense reaction was probably because the electric shocks matched Jisu’s tastes perfectly. After reaching her first climax from the shocks, she trembled as the dildo stirred her insides, driving her straight into a second orgasm. With back-to-back climaxes, maintaining a squatting position was obviously impossible. As she collapsed to the floor, I quickly grabbed her leash to keep her head from hitting the ground.
“Hiik… Hauk…♥” “You broke posture again.” “S-Sowwy…” “If you can’t even last ten minutes, how do you expect to serve my cock properly?” “Th-That’s… I tried to hold on… But every time the electricity zapped me, my head went blank and my legs gave out…”
As Jisu panted out her excuses, I looked down at her with cold eyes.
“Are you going to make the same excuses when you cum during service later?” “N-No… That’s not…” “Haa… I gave you four chances and you failed every single one. I’m disappointed.” “S-Sowwy… Hik! Please give me one more chance…” “So you can collapse again before five minutes are up?” “Th-This time I can do it…! I’ll hold on no matter what…”
Jisu looked up at me with desperate eyes, but I firmly shook my head. This was enough. She had failed to meet the condition I set, but that had never been the real goal of this session anyway. The purpose was to drain her stamina and make her fully aware, through punishment, that she was my obedient bitch. Judging by how desperately she was begging for another chance, that goal had been achieved.
“If you keep collapsing like this and end up getting hurt, who’s going to take responsibility?” “Th-That’s…”
It seemed better to stop here before Jisu actually got injured. I had been planning to demand service while testing her skills, but seeing her desperate expression gave me an amusing idea.
“Fine. If you really want to continue, I’ll give you a different mission.” “R-Really?” “But this one will be harder. You might even think it’s better to just give up.” “I-It’s okay…! As long as I can be recognized as Master’s cumdump bitch… I-I’ll do anything!” “Good. Then get on the bed and lie down with your ass raised.” “Yes…!”
Jisu hurriedly climbed onto the bed and assumed the position I had ordered. She stuck her ass out as far as possible, like a cat stretching, and I began to gently stroke her cheeks—soft and affectionate, almost like a caress.
“Huuut… Master’s hands are touching my ass…♥” “How does it feel? Good?” “Yes♥ It feels really nice…♥” “Good. From now on, no matter what I say, you answer that it feels good. That’s the mission.” “It feels good…♥”
Her voice had melted into a sticky, syrupy tone. I picked up my phone and activated the vibe app. When I set it to a light pattern that gently teased her pussy, her body began to tremble.
“How is it? I started with a light pattern.” “Huuut… It feels good…♥ The dildo is vibrating softly inside my pussy…♥” “Really? Then how about this?”
I switched to a chaotic pattern that felt like it was stirring up her insides, and her body shook violently in response.
“Hugut…! Hiiit♥ It feels… good…♥” “Tell me exactly what feels good.” “M-My pussy is being stirred up by the dildo… Everything inside is getting messed up… It feels too good♥” “Is that so?”
This time I swung the electric whip against Jisu’s ass.
“Hugiiiit♥” “How about this?” “Haguk♥ Heuk♥ Hugiiiit♥” “Answer properly.” “Hiit♥ Huguk♥ It feels… good… I’m going crazy…♥”
She was already trembling from the dildo relentlessly tormenting her insides, and now the electric shocks were added on top. There was no way she could endure it. She kept repeating that it felt good, barely conscious. I continued whipping her ass while watching her reactions, only stopping the whip and the dildo when she was on the verge of passing out.
Once the overwhelming stimulation disappeared, Jisu gasped for breath as if regaining her senses. I removed the dildo holder from her ass and immediately thrust my cock into her pussy.
“Heguiit♥” “How does this feel?” “It feels good…! Master’s cock♥” “I’m glad you like it.”
Holding onto her bound arms like handles, I began to move my hips. I had originally wanted to use the red handle on her head, but the position didn’t work out, so I gave up for now. I could try it next time.
“Hit♥ Haang♥ Master’s cock… is going so deep…♥” “And how does that feel?” “It feels good… Haang♥ It feels amazing♥” “Is that right? Not bad for me either. You’re decent enough to use as a cumdump bitch.” “Hut♥ It feels good♥ I’m so happy… I can be Master’s bitch… Huut♥” “Really? Say it properly again.” “Heut♥ I’m so happy… I can be Master’s cumdump bitch… Huit♥ I really love it…♥”
Even with her arms bound, a dog collar around her neck, and being fucked doggy-style on the bed, she kept repeating in a genuinely happy voice how glad she was to be my personal bitch. If I didn’t get turned on by this, the problem would be on my end.
Slap! Slap…! Thud…. Squish! Thrust…. “Haang♥ With Master’s cock…♥ Heguk♥ I’m cumming…!” “I’m about to cum too.” “Hit♥ It feels good…! Please cum as much as you want inside your bitch’s pussy… Huut♥ Fill me up♥” “Alright. I’m cumming.” “Huiiiik♥ It feels so good♥”
Enjoying the way her vaginal walls pleasantly squeezed my cock with every thrust, I poured every last drop of my remaining semen deep inside Jisu’s pussy.
Spurt, spurt, spurt! “Haaang♥”
Jisu reached her climax as she felt my cum flooding her insides. She kept twitching her pussy as if trying to accept every drop, and the moment I pulled out, she squirted violently.
Squirt…! “Heu…” “Whew… That was good. You okay, Jisu?” “It feels good…♥” “…You look half-gone.”
She still hadn’t regained her senses, probably because she had cum so intensely. The training from earlier must have left a strong impression; she kept murmuring that it felt good. This was enough for today. My own legs were shaking after cumming four times—I was on the verge of collapsing myself.
Gathering what little strength I had left, I untied the stockings binding her arms and removed the collar from her neck, then reached out to carry her to the bathroom.
“Jisu, let’s go wash up properly now.” “…Hik♥” “Jisu?” “It feels… good…” “Uh, yeah… Okay.”
Jisu seemed completely drained of strength. No matter how much I pulled her arm, she just lay face-down on the bed, trembling. Did I go too far today…? Since she had asked to wash up, I picked up the half-conscious Jisu and headed to the bathroom.

“Washing Jisu up and putting her to bed was a real ordeal.” “…You crazy bastard.” “Hey, it was Jisu who wanted to do it, okay? But her passing out on her own was a bit much.” “Even so, how could you make your girlfriend pass out? You’re literally just an animal.” “No, I’m innocent here…”
A week later, on the way back from the gym. After Seo Taehyun, my personal trainer, asked for sex stories and I told him one, he was now looking at me like I was actual trash. It was true that I had been pretty rough with Jisu that time, but still, getting that kind of reaction hurt a little. I had even toned it down when telling the story, yet this was the response. How disappointing.
“Haa, I didn’t teach you how to work out so you could use it for this.” “Come on, at least I put it to good use, right?” “Yeah, well… As long as you two enjoyed it…” “See? We’re just playing our own little game.” “Ugh… I shouldn’t have asked.”
Taehyun sighed and shook his head. I could understand his reaction to some extent. He had been asking me for advice on how to progress with Jihye, and instead I had told him a story that went way beyond just progressing. Of course he would be dumbfounded. Maybe I should have told him something else, but honestly, all my stories were pretty spicy, so there wasn’t much else to share.
“By the way, is it okay to talk about this so casually? It’s pretty private.” “Ah, it’s fine. Jisu said it was okay to tell you.” “Really?” “Yeah. She even told me to go into more detail and help you get together with Jihye faster.” “…Even if you say that, it’s not that easy.”
Our conversation naturally died down as we arrived in front of a coffee shop. It felt awkward discussing such things in a crowded place, and besides, we needed to order drinks. Taehyun chose an iced americano while I went for an iced americano with a shot of espresso. As I naturally reached for my card to pay Dutch, Taehyun stopped me.
“I’ll pay.” “Huh? Suddenly?” “In exchange, help me with some advice. There’s something I can only talk to you about.” “Sure. Sounds good to me.”
Free coffee and an interesting story? No reason to refuse. We waited at the counter, received our drinks, and found a quiet spot. After settling into a secluded area, Taehyun sipped his americano and carefully began to speak.
“It’s… not really a big deal, but…” “Yeah, yeah. Go ahead.” “When I met Jihye last time, I think I made a mistake…” “A mistake? What kind? What happened?”
Don’t tell me they couldn’t resist the mood and had raw sex…? But Taehyun and Jihye were still a fresh couple who hadn’t even had their first night together. If they had done it raw on their first night, that would be quite the mistake, but knowing the two of them, something like that didn’t seem likely. So what could it be?
As I looked at Taehyun with curiosity, he slowly opened his mouth.
“Well… Last Saturday, Jihye suddenly called and asked if I had time.” “Ooh, did you two go on a date? And then?” “She said she had a cute cat at home and asked if I wanted to come see it.” “Hmm~. Wait a second. Does Jihye even have a cat at home?”
No matter how hard I tried to remember, I had never heard anything about Jihye owning a cat. If she did, Jisu would have made a huge fuss about going to see it. Since that hadn’t happened, as far as I knew, Jihye had never kept a cat. Wait, could this be…?
“No.” “Then…?” “Yeah, it was… some kind of event.” “Whoa… Jihye? Seriously?” “Yeah…” “That’s huge. What, did Jisu put her up to it?” “Anyway, so I went to Jihye’s place. Of course, I thought there was actually a cat.” “Ooh, so that’s how you ended up facing ‘cat Jihye’.” “Yeah… But then…”
Taehyun let out a sigh and drank his coffee in silence for a moment. After finally setting the cup down, he looked at me and carefully spoke.
“I think I made a pretty big mistake.”
