Strategic Mating Partner – Chapter 39

Author: nicotine

‘Ah, huu, uhh…!’

His mind screamed that he’d rather die than let out such embarrassing moans, but he couldn’t control himself. His waist moved on its own to take Sejin deeper, and his inner walls clung tenaciously to the hard length, refusing to let go. Moreover, even after reaching his peak, the sensation didn’t fade but continued, leaving him overwhelmed and lightheaded. It was a frightening experience rather than a pleasurable one. He was bewildered and disbelieving that he could lose control like this over mere sex. And the fact that it was with Sejin made the reality even more unbearable.

Taehyun had always believed that sex was more about an exchange of emotions than a release of physical desire. Relieving oneself was something one could do alone, but feeling another’s body heat, striving to give pleasure, enduring extreme unhygienic conditions, and pressing together the most vulnerable and intimate parts of their bodies—he thought these were acts that required affection as a foundation. Of course, sex wasn’t something that should only happen between lovers, but he’d always had that sort of fantasy. Even though he’d shattered that illusion by realizing he didn’t love anyone enough to want to do that with them, he had once held such a belief.

However, looking back on his acts with Sejin, it felt like something only people with nothing but raw desire left between them would do. They had thrust and rubbed against each other’s wet skin until there was nothing left to wring out. He couldn’t even estimate how much they had cum by the end. It was the first time he had reached such a merciless climax. The fact that they had to continue this regularly was quite a burden for Taehyun.

‘Ha….’

Regardless of his troubled feelings, they were in this together, so he had to continue cooperating with Sejin. With a heavy heart, Taehyun ruffled his hair and sent a message to Sejin.

7:36 PM Got a 10

The read receipt appeared almost immediately, and a reply soon followed.

117:41 PM

It was a negligible difference. Taehyun sighed deeply and typed a reply.

7:42 PM Check again tomorrow morning

The maximum level allowed for competition entry was 20. He needed to confirm how long these low numbers would last. He could only hope his pheromones would stay dormant for a long time.

Taehyun arranged to meet Sejin again four days later. The below-limit levels lasted for exactly three days. The day after their encounter, it peaked at 10, the next day at 14, and the day after that at 19. Sejin’s levels weren’t much different. On the fourth day after their encounter, his levels went up to 27. This was a level difficult to detect in everyday life.

In any case, to reliably keep their levels below 20, they would likely need to have sex every three days. It was difficult to determine an exact pattern with just one instance, and they’d need more data, but that was his current assumption.

‘Every three days… how many times would we have to do it until the Olympics?’

Isn’t this too frequent? He wanted to ask those with experience, but unfortunately, he had no one to ask. It was a topic related to sexual activity, so it wasn’t something he could easily ask others about, and furthermore, no one would want to reveal or share their experience with a mating partner. Even if it wasn’t illegal, it was the kind of scandal that could be fatal for a sports star.

Regret washed over him belatedly. While he felt mentally drained, the long-suffering side effects of the medication were gone, leaving him feeling physically light. It was fortunate that there were immediate effects. If it hadn’t been effective, he might have gone to apologize to Sejin and asked to stop this whole thing.

‘…….’

Regardless of Taehyun’s apprehension, the day for their second encounter arrived quickly, and he headed to Sejin’s house once again. Driving into the grounds of the massive mansion, he couldn’t shake the feeling that he was doing something wrong. The mansion where Sejin lived was truly an impressive structure. The architect who designed such a magnificent house must have envisioned a refined, deserving owner with sophisticated tastes, living there with dignity. And what were they doing there? Two young men in their twenties, panting and engaging in sex as mating partners. Taehyun found it hard to shake off these cynical thoughts.

“Come in.”

Taehyun, somewhat familiar with the place after his previous visit, walked from the parking lot to the front door, where Sejin opened the door for him. The sight that greeted him inside was still grand.

“Are we doing it right away?”

Sejin went straight to the point without even the usual courtesy of offering coffee or tea. Even if it’s just for show, shouldn’t he offer a guest some water? Taehyun sighed and said,

“I think we need to discuss something first. Can I have a glass of water first?”

As Taehyun walked towards the living room sofa instead of the bedroom, Sejin nodded with an impassive expression.

“Yes.”

While Sejin went to fetch water from the kitchen, Taehyun took out the prepared form and a pen from his bag. A moment later, Sejin returned with a tall glass of cold water and sat across from Taehyun with a puzzled look. Taehyun explained immediately,

“Since we’re doing… this… for the same purpose. I think it’s good to clarify what we each want.”

He tried to speak casually, but he couldn’t hide his embarrassment, and his ears started to burn. Taehyun ignored the heat in the back of his neck and continued,

“You have your preferences, things you like and dislike, right? Things you don’t want to do, things you want to do…. I’m suggesting we share those. Judging by our current levels, we’ll probably have to do this almost every four days, and it would be a pain if our preferences don’t align.”

If they were lovers, adjusting to each other’s preferences without having to explicitly state them would be part of the relationship, but Taehyun and Sejin weren’t in that kind of relationship. Therefore, he had to maintain a business-like attitude. If he made a mistake and acted ambiguously, it could be burdensome for Sejin. Sejin’s eyebrows twitched slightly at Taehyun’s suggestion before he spoke.

“Let’s do that.”

Then he picked up the pen Taehyun offered.

“Can I write down everything that comes to mind?”

Hmm, I haven’t thought about that. Taehyun came up with an answer on the spot.

“Write everything down first, and if it seems like too much, we can adjust the number and choose a few each.”

“Okay. Then…”

Sejin nodded and started writing something down from the first line without hesitation. He must have had some complaints about last time. Feeling slightly guilty, Taehyun watched Sejin cautiously as he slowly wrote down his own conditions. In fact, he felt embarrassed because he had so few conditions that he didn’t even need to think about a limit. Soon, Taehyun stopped writing, put the pen down on the table, and checked Sejin’s paper.

“Finished?”

“Yes.”

Immediately after exchanging their written forms, Taehyun had to desperately suppress a cough that threatened to escape.

The number of times during intercourse should be until both parties are satisfied.
Refrain from sexual relations with other partners while maintaining the mating partner relationship.

He had expected Sejin to add various things since he asked if he could write everything that came to mind, but it was simpler than expected. It made Taehyun’s long list look even more embarrassing. Seeing Taehyun’s conditions, Sejin frowned slightly and said,

“Aren’t these obvious? What do you take me for?”

It was understandable since Taehyun had also focused on making the act as comfortable as possible, so his list consisted mostly of things he didn’t want rather than things he did want.
