The Contractual Arrangement
Yeongseon, feeling anxious, covered her lower body with the duvet and sat up. Who was it? "Kangmin. Who’s outside?" Kangmin, who had just ejaculated spectacularly inside Yeongseon, was in a daze. It was fine that he’d forbidden her from touching her own clitoris, but he hadn't thought about the play that would follow. He wanted to make her perform a "cleaning" blowjob, but he also had to let Yerim, who was standing outside, come in. Ah, that would work.
"Don't worry about her, Noona. Just clean it with your mouth first."
"W-with my mouth...?" She had never even performed fellatio in her dreams. This was a play she was experiencing for the first time in her life. Of course, she had seen actors alternating between anal sex and fellatio in her brother's adult videos, but she had never imagined herself doing such a thing. Yet, Kangmin was thrusting his glistening cock right in front of her nose, demanding fellatio. He wanted her to clean with her mouth the very object that had been sliding in and out of her anus just moments ago, sticky with semen and love gel. When they worked part-time together, he had been such a sincere, kind, and cheerful junior who was easy to talk to. Why was he so violent and cruel when they had sex? She felt like crying, but she also wanted to clean his cock. Her heart was a mess. Why was she like this when she had gotten the play she wanted most? She had just climaxed so intensely. Her wish had come true, so why did she feel this way?
"Kangmin. I... I've only kissed you once. This is too much..." Yeongseon looked up at him pitifully. The human heart doesn't just desire one thing. You can hate someone and love them at the same time. There are things you truly hate but can't throw away. You might want to keep someone by your side even though looking at them hurts. Yeongseon was the same. She had a desire to be bullied intensely, but she also wanted to be treated kindly. If she had anal sex while being miserably berated, couldn't he be at least a little kind to her?
"You said you'd do anything."
However, Kangmin had no intention of being kind just yet. This level of play wasn't enough to satisfy his Degrader tendencies. A little more. He felt like he would only be satisfied once he had treated her so harshly that she cried. Right now, he wanted to torment her more. The level of sex that had risen because of Yerim was inevitably applied to Yeongseon as well. In the end, hiding the tears gathering at the corners of her eyes, Yeongseon brought her trembling tongue to Kangmin's cock. A session of fellatio, consisting of light flicks of her tongue, continued for a while. Then, Kangmin asked a question.
"Noona. Tell me the password to your front door."
"Eight, six, seven, four. And the star key."
Ah, now Kangmin would be coming in and out of her house as he pleased. Thinking about Kangmin coming over to her place made her lower body tighten. The thought that she wanted him to be kind to her was slowly disappearing as he treated her violently. Regardless, what Yeongseon had wanted was an incredibly hardcore play. Her craving for kindness earlier had been temporary, satisfied once her desire was met. As Yeongseon continued the fellatio, she heard a beeping sound from outside. Someone was coming in. Yeongseon was startled and pulled her mouth away.
"It's fine. It's Yerim. Keep going."
Telling her to keep going because it was Yerim... This Kangmin guy, he really was a beast. Yeongseon's face turned bright red. Even so, this was too much. As she hesitated, Yerim opened the door and leaned against the doorframe. Yeongseon closed her eyes tight, trying not to look that way, and opened her mouth to swallow his glans.
Yerim was very disappointed. 'In the end, Oppa had sex with Yeongseon-unnie... And my magic power doesn't go up even if Yeongseon-unnie masturbates while watching the video. I'm the only one losing out here.' On top of that, Yeongseon was cleaning Kangmin's cock with tear-filled eyes. Her anus was slightly dilated, and semen was leaking out from between. He really did perform every kind of hardcore play. Then what about me, a succubus? The only thing I'm good at is using my body. I'm not going to be thrown away, am I? Yerim stood at the entrance of the room, lost in complex thoughts.
"Kangmin-oppa, does it feel good?" She asked bluntly, hoping he would notice her upset heart, but Kangmin, busy with his cock in Yeongseon's mouth, didn't even pay attention and just nodded. She sighed in frustration. Charles pulled a piece of paper from her pocket. She had written it during the six hours she spent waiting for Kangmin's call at the cafe earlier. That made her feel a little better. While Charles was sitting in the cafe, men had offered her six drinks, cookies, cakes, sandwiches, and even a roll cake to get her number. She had rejected them all. Still, the men had left them on the table, saying, "You ordered them, so please eat them." Honestly, it was delicious. Sweet desserts, cheese and ham toast, bitter coffee, and drinks with all sorts of fancy flavors. It was the best feast, one that couldn't even be found at a festival in the Demon Realm. But Charles hadn't been able to enjoy it properly because she was busy writing the paper in her hand. What Charles was holding was a contract. She had made it for Yeongseon-unnie. To adjust the terms of the three of them and to organize their future relationship. 'I never thought I'd end up writing something like this...' She had wanted Kangmin-oppa to stick only with her. She felt gloomy looking at the sentences she had agonized over, writing and erasing hundreds of times.
1. Sexual relations between Kim Kangmin and Jeon Yeongseon are permitted only once per week.
2. If Kangmin goes on a date with Jeon Yeongseon, he must do the same with Charles. The reverse does not apply.
3. Spending time with Jeon Yeongseon shall not lead to neglect of Charles.
4. Jeon Yeongseon shall not disclose her romantic relationship with Kim Kangmin to others.
5. Violation of conditions 1-4 may result in a 2-month restriction on meetings between Kim Kangmin and Jeon Yeongseon.
6. The above terms may be modified with the consent of all three parties.
It was a contract she didn't particularly like, but it was better than having nothing. She reviewed the contract once more. But if they met even after she told them not to, what penalty should she give? Confiscate the magic of cock enlargement for two months? That would be a loss for her, too. Charles sighed. The contract Kangmin and she had written, and all the contracts, were too favorable to Kangmin. There wasn't even a proper penalty. It was because she had rewritten a standard contract. 'But if I don't do this, humans will refuse the contract.' The contracts suggested by demons would make a human seeing them for the first time freak out. Like taking their soul as a penalty for breach of contract. Or demanding an enormous amount of treasure. Humans had become shrewd and would never sign. And how had Kangmin been? When they first met, he had tried to kick Charles out of the house. That was why she had suggested a contract with almost no penalties. 'With such generous terms, he wouldn't kick me out unless he was crazy, right?' But now that Yeongseon and Kangmin were actually having sex, Charles's heart was filled with anxiety. He wouldn't kick her out, but he might treat her like a broom left in the corner. That was why she had hurriedly brought the contract for Yeongseon. Honestly, she had wanted to insert a 7th item into her own contract with Kangmin: 'He shall not abandon Charles and will do his best to treat her well.' But because of her pride, and for fear that Kangmin would dislike it, she couldn't bring herself to add it. Seriously, Kangmin-oppa. He was so blessed. He ended up living with a kind succubus like her. And he didn't even know how to be grateful...
Charles, who had been watching Yeongseon's fellatio for a while, walked into the room. At that rate of light, flicking fellatio, it would take all day for him to cum. Yeongseon was already grimacing in pain. Her jaw was stiff from the first-time fellatio. Yerim tapped Kangmin. "Kangmin-oppa, look at this before you do more."
"I want to cum one more time."
"I'll do it for you a lot later. Let's talk first."
Yerim spread the contract out on the bed. Yeongseon also stopped the fellatio, massaged her jaw, and opened her eyes. She felt embarrassed to be wearing only her underwear, but the two of them didn't seem to care. It would look strange if she hesitated, too. She covered only her lower body with the duvet and looked at what they had brought. "What is this? And who is Charles?"
"That's my nickname."
A bright red contract, as if written in blood. And the names of herself, Kangmin, and Charles appearing. Yeongseon scanned the contract suspiciously. "You guys are really serious sex partners, writing contracts like this. Is this for me?"
"Yes. The three of us should look at it, and if it's okay, sign it."
As Yeongseon read through the items of the contract one by one, she suddenly felt sorry for Yerim. It was clear how much she wanted to monopolize Kangmin. They weren't just sex partners; didn't she like him? I must have interrupted and gotten in the way. But I'm also going crazy wanting to have sex with Kangmin. So please, bear with it. Hmm, but meeting once a week is too little... Yeongseon looked into the contract, searching for a way to increase the frequency. It was a joke-like contract, but she felt a bit aroused thinking that she was bound by it. "If you adjust the frequency part, I'm fine with it."
"Me too, the frequency and... if you add one more condition."
I was thinking while looking at the contract that it wasn't bad. Well, even if she added many conditions, Charles was a succubus who couldn't live without a man. She had to make some concessions. But I didn't want to limit how many times a week I met Yeongseon-noona. Should I just promise Charles sex once a day? What if I get sick or tired then? My head was getting complicated. I set it aside for a moment and added one sentence.
'7. Yeongseon cannot touch her own clitoris or vagina without Kangmin's permission.'
"Hey."
Yeongseon-noona turned bright red and poked me. But I pretended not to notice. Hmm, but the sentence in my contract doesn't seem to be here? Was it clause 3... I searched through my faint memories. It seemed I would only remember the exact sentence if I looked at the contract again. For now, I put my hands behind my back. Usually, contracts would be made so you could see them whenever you wanted, right? As I thought strongly, "Come out!" in my head, I felt like my back was spitting out a piece of paper. It really worked! Yeongseon-noona was busy reviewing the contract on the bed. Meanwhile, I read my contract. Clause 3. '3. All magic power generated between Kim Kangmin and Charles belongs to Charles.' Hmm. Reading this, I felt like a lightbulb was about to turn on, or maybe not...
