Can We... Become Rich?
"Yerim. Clause number three of my contract. If we modify this, can I receive magic power too?"
I whispered to Yerim, but she shook her head.
"If you pour water into someone without a vessel, it just spills. Ordinary humans cannot store magic power."
So, ordinary humans can't store magic power. I tapped my head rhythmically. According to Charles, the mechanism for generating magic power is the release of desire. But the magic power generated when I masturbated went to Charles, and my sister's magic power simply vanished. Neither of us had a storage vessel. What was the difference between Youngsun and me? The release of desire was the same. Then what else was different? Was it whether or not the attribution of magic power was written into the contract? Could that be the only difference?
As my thoughts reached this point, my heart began to race. Perhaps I could obtain magic power from Pornhub videos. I tapped Yerim on the shoulder.
"Add this to the contract, too. Between Jeon Youngsun and Kim Kangmin..."
Hmm, it would be better not to use the word "magic power." It was best if as few people as possible knew that Yerim was a demon. I whispered into Yerim's ear.
"Right before the contract is signed, add a clause stating that the magic power generated between Youngsun and Kangmin belongs to you."
Yerim, who had been unhappy with the current situation, suddenly beamed.
What if I added this condition and magic power actually flowed in? If the destination of the magic power was determined by the clauses of the contract? Then I could easily accept even the most unreasonable demands Youngsun made. I could gain magic power without working, and it would become the foundation for research into extracting magic power from Pornhub. It was too much magic power to give up!
"That's fine, Youngsun. Instead of once a week, how about twice a week?"
Wow, she's really stingy! Why not ask for more? Even though she intends to take all the magic power generated between the two of us anyway. But if I increase the frequency and sign the contract, and no magic power comes in, Charles will be the one truly screwed. If I hadn't been messing around with Youngsun, it would have all been her own magic power. Fortunately, Youngsun seemed satisfied enough with the contract being increased to twice a week. However, before stamping it, she added more requirements.
"...I'd like there to be a safeword."
Well, in a hardcore relationship like ours, that's only natural. I added the eighth clause.
8. If Jeon Youngsun says the safeword, all play will cease immediately.
"And one more thing. I don't like you having sex with other men, Kangmin. When we film, we'll use my phone. If you want to upload the video, you need my permission."
She said she'd only say one more thing, but she ended up saying three. Still, I added clauses 9, 10, and 11 without a single complaint. I pressed down hard with the pen. Youngsun seemed to like that, as she clutched the front of her bra and looked at me. Her eyes were like a cat's. Hmm. I do like hardcore play, but even that requires a minimum level of consensus.
"Is this enough?"
"...Good. Then do I just sign here?"
"You just need to place your finger on it."
Yerim explained, and before Youngsun could stamp it, she waved her hand over the contract. Characters spreading like blood inserted themselves into the middle of the document.
The magic power generated between Kangmin and Youngsun is attributed to Charles...
The clause numbers shifted one by one, but Youngsun didn't notice. Her thumbprint was pressed next to her name. I, and Charles, also pressed our thumbs. Without even a sting, the red print was set.
"I'll keep this in the drawer."
Yerim folded the contract and stored it in Youngsun's desk drawer. She had said that contracts with demons were kept in the heart, but I guess they work even when stored in paper form like that. Once that was done, Yerim signaled me. She was dying to experiment right away. Could we really earn magic power without having sex directly or setting up a dream? I was curious too. Could I really earn enough magic power to build a one-man harem with Yerim? I asked Youngsun, who would provide the answer to my question.
"Noona. Do you still want to climax with your pussy?"
Youngsun wrapped herself in the blanket and nodded. Her face turned red, and she kept glancing at Yerim. She must be embarrassed to talk about this in front of her. Should I make her even more embarrassed?
"Then, I'll allow you to masturbate here."
We wouldn't have sex. I wanted to eliminate any factors that might interfere with the experiment as much as possible. I wanted only Youngsun's desire to be released. If I intervened, the magic power generated during ejaculation might contaminate the experiment. Youngsun's face twisted with disappointment, as if she had been expecting me to penetrate her with my cock. But thinking that masturbation was better than nothing, she wiggled her body.
"Do I have to show Yerim too?"
Yerim didn't want to interfere with the experiment either.
"Well, I'll step out this time."
She even went outside the house entirely. Yerim sat on the stairs next to the house and waited.
'Ah, please. I hope the magic power rises.'
While Yerim waited anxiously, I pulled back the blanket Youngsun was wrapped in. Her body was beautifully toned, shaped like a competition swimsuit. Her pubic hair was neatly trimmed along the bikini line. And the garter belt wrapped around her lower abdomen.
"Masturbate like you usually do."
Youngsun swallowed hard and placed her hand on her clitoris. It had dried out a bit during the commotion of writing the contract, but as Kangmin watched her, she quickly became wet again. I watched her moving fingers and opened my mouth.
"Did you trim your nails this short because you thought we'd have sex today?"
"Y-yes..."
Nails trimmed short to avoid causing scratches. To think I'd have a sex partner so obedient to my desires. It's all thanks to Yerim. I smiled, thinking of Yerim waiting outside. I should have sex with Yerim when I get home today. As I stared and smiled, Youngsun blushed. She spread her legs a little wider. The M-shape opened further, revealing the deep crevice of her pussy. Should I help her out a bit? I kissed her outstretched foot lightly. It should be fine to be a bit gentler now, right? Her toes curled. The scent of the body wash still lingering on her skin hit me. Small toenails, toes wiggling cutely. I opened my mouth and lightly bit the tip of her ring toe.
"Haa-"
Her fingers moved more diligently. I matched her rhythm, brushing over her clitoris with my tongue and darting between her toes. Embarrassed, she rubbed her clitoris even faster. I had wanted to try this since I saw her feet. Her reaction was surprisingly fun. It wasn't dirty at all. On the contrary, it was smooth. I continued kissing my way up. Ankle, shin, knee, thigh. Surely, just kissing wouldn't satisfy my desires. Thinking that, I bit the inside of her thigh.
"Haa, it feels... strange."
She had never experienced masturbation while someone was caressing her like this. As I kept kissing her, Youngsun's body trembled. She seemed quite aroused. After a few minutes, she exhaled raggedly—
"Kangmin, kiss me. If you do, I think I'll come..."
She pleaded with moist lips. Hmm, even this kind of ordinary, pure love can be quite erotic. I couldn't resist and layered my body over hers. While Youngsun masturbated, I teased her lips with kisses. I thrust my tongue deep inside and bit her. Her breathing became violent. Then, her tongue invaded my mouth. As Yerim had taught me, I wrapped my tongue around hers and sucked on her lips.
"Hk, hnnngh-"
Youngsun's body jerked and trembled lightly. Hmm, did she come? Was this enough? As if to answer my question, her fingers, which had been brushing her clitoris, stopped, and her eyes glazed over. Good, then let's go ask Yerim!
"Youngsun Noona. Today was really great. Especially the anal part. I was completely turned on."
"Don't say things like that. It's embarrassing."
Youngsun lay there, covering her face with a pillow and sighing. Since her pussy was still a "new product" and she had been taken from behind first, it was natural for her to have complicated thoughts. I gave her one last kiss on the lips and left the room.
"Rest up, Noona. See you at the part-time job tomorrow."
"Y-yes."
Youngsun sat up and waved. Having experienced an extreme climax followed by a soft one, she seemed too exhausted to even stand. Her face was already nodding off. Should I head out now? As I put on my clothes, my hands trembled with excitement. Having sex with Youngsun was great, but checking if the magic power had increased was even more thrilling. Had Charles's magic power increased? I thought it would work. Fundamentally, only the target of the contract had changed; the content of the contract itself was the same. Like coding, if the core of the code is the same and only the variables change, the code should work without any problems. But magic was a completely unknown territory. I wouldn't know until I asked Yerim.
When I stepped outside, Yerim was sitting on the landing, hugging her knees.
"Did it work?"
Yerim walked out the front door without a word, her expression blank. She looked disappointed, as if there had been no results. Damn it, did it really not work? But as soon as I stepped outside the front door, Yerim suddenly jumped up. Her well-shaped breasts bounced along with her.
"It worked!!! Magic power came in! It's much less than doing it directly! It's really only about one-hundredth, but it came in!!! Oppa, you're a genius! No one in the Demon World had ever experimented with this!"
And she hugged me and spun me around. Is it true? Then, if we can just figure out a way to attach the contract to Pornhub videos, can we become rich? Do you have a method in mind?
At that, Yerim shook her head.
"I don't know how to do it yet. But we need to get tattoos, find a camera in the Akashic Records, and change our nationality—there's so much to do! For now, let's just film a light video and upload it to see! Just something like an introduction video!"
Yerim bounced around, seemingly thrilled just thinking about it. I was excited too. Really, does this mean I can build a one-man harem now!!!
