Here is a direct translation of the story:

Mika (24) Masaru's First Sex Friend

This is the woman who started me on my path to making tons of sex friends.

I had started a band for fun with some local friends, and we would do this thing where several bands would rent out a house and play private shows just for our circle of friends. Mika was on the staff at that house (the one who brought us food and drinks).

Later, we ran into each other at the supermarket, and she was the one who asked for my contact info.

She had a body that would probably be a hit in Brazil, a high nose, and thick lips that were incredibly erotic. Dreaming of a one-in-a-million chance, I started texting her regularly.

The chance came quickly.

Mika was a divorcee with two kids. The guy she had been dating until recently was Shingo, a junior member of a band that I often played against, a guy I was indebted to. He looked like the phantom third member of Onigoe Tomahawk and was popular with both men and women.

She contacted me saying she wanted to talk about all that stuff.

On a weekday when Mika had the day off, her kids were at daycare, so we decided to talk at her house. Well, the content of the conversation was what I expected: a complaint that she and Shingo were on-again, off-again, and that he was also messing around with another woman. That other woman was also Mika's friend, and he was complaining to Mika about that woman, saying stuff like "you're better after all," and now he was trying to get back with Mika, so she didn't know what to do.

She said the reason she came to me with this was that out of all her male friends, she trusted me the most.

At that moment, I decided to make Mika my sex friend.

From the expression on her face as we talked, her tone of voice, her gestures—I knew without a doubt that she would fall.

So, I told her my (extreme) personal theory on relationships between men and women.

① "If you start dating, a breakup will come someday. Once you break up, you can't even be friends anymore. Even if you manage to get married without breaking up, most of the time you just turn from a man and a woman into family. But if you're friends, you can stay friends forever. So let's you and I be the best 'friends' forever."

To this, she chimed in, "I see! Yeah, you're right!" so her becoming my sex friend was a done deal. I'm married, and I don't want any trouble that comes from a woman getting into my family life or getting jealous.

Most men who fail at having affairs probably approach women from a lover's angle, saying things like "I love you" or "Let's go out," just because they want to fuck.

That's why the woman starts thinking she's number one in his heart, and out of jealousy and loneliness, she starts acting in ways that cause trouble for the man and making selfish demands.

To prevent that, I believe you have to clear the hurdle of making the woman realize that she is, to the bitter end, just a friend.

② "The ones who can have skinship are the ones who have the deepest bond among opposite-sex friends. No matter how much of a friend you are, you wouldn't want skinship with someone you can't trust." (Here, I immediately followed up by telling her a story about my past trauma and being a gynophobe, and told her that because I trust her, I just told her my most important secret). "This way of thinking is pretty strange, and you might be put off by it, but that's exactly why I wanted you to know how important a female friend I can have skinship with is to me. A guy who thinks like this is a turn-off, isn't he?" I said.

Hearing ② after already being told she's the "best friend" in ①, there aren't many women who would answer that they're put off. I've tested this on several of the sex friends who came later, and every single one of them answered, "I'm not put off! In fact, I'm happy you told me!"

Also, by talking about my past trauma, I smoothly implanted the idea that I don't like sex, but I do like fellatio.

Once she said she wasn't put off, I immediately acted overjoyed in an exaggerated way. I'd hug her and get excited.

I gave her a light kiss on the cheek, not the mouth, and with my arm around her shoulder, I'd say in a relaxed tone, "I wasn't sure if I should say it, but I'm glad I told you." The thing not to forget here is that, in the first place, she came to me for advice. So, with my arm still around her shoulder, I returned to her consultation.

③ "Having a boyfriend is a good thing for a woman. But there's no need to continue the relationship if you're just going to fight, and if you get back together out of loneliness, you'll just repeat the same thing. You have a friend you can have skinship with, so don't get back with a guy you already broke up with once. Just find a new guy. And if the new guy doesn't work out, you can just find the next one. I'm your friend, so even if you have a boyfriend, it's not two-timing."

I told her something along those lines. Hearing this after the flow from ① and ②, and with some light skinship happening, she accepted everything I said. Also, I would ask "right?" and "don't you think?" at various points, and by drawing out a "yes" from her, she starts to delude herself into thinking these are her own ideas. With that, her consultation was resolved, so for the remaining time, I steered things by saying, "Well, I have to leave at XX o'clock, so until then, let's talk about something while we have some skinship," and we headed toward our first play session.

She had said that she was bad at blowjobs and wasn't confident, that her jaw gets tired, and that she's never done it for more than 10 minutes.

I don't train them on technique from the start.

I just said, "How about we just have a normal conversation while you have it in your mouth and nibble a little?"

If she had tried to do it intensely or performatively, I would have stopped her.

I told her it's more relaxing to talk with skinship than facing each other, right? And that we're just using a blowjob for that.

Imagine it's the same as the relaxed atmosphere you get when talking with an arm around someone's shoulder.

While nibbling, Mika started talking about her past boyfriends, her kids, her job, and so on.

I just listened to it all, saying "uh-huh, uh-huh."

Unlike men, women, when they say they're asking for advice, often aren't really looking for an answer.

They've already made up their minds, and they want the person they're consulting to agree with them.

They just want someone to vent their complaints to.

When it was time for me to go and I told her, she was shocked to realize she had been giving me a blowjob for over 90 minutes straight.

And she was also shocked that I was about to leave without cumming.

In a text after I left, she said, "I thought men couldn't be satisfied unless they came, and that they'd want to leave right after they did."

I replied that that's not skinship.

I told her that since I can't masturbate, I'd be grateful if she could get me off, but unless a woman feels like she wants to get me off, I'm fine not cumming. Here's the important part: I told her, "Hypothetically, even if I did cum, that doesn't mean the blowjob is over. I'd want you to keep it in your mouth until it's time for me to leave. That's what I consider skinship."

To the end, skinship is what's necessary for opposite-sex friends.

Mika was delighted, thinking that I considered her my best friend.

However, a woman is bound to be left frustrated if a man leaves without cumming, and indeed, Mika also said she wanted to get me off.

One of my personal theories is that a man can never leave a woman who's good at fellatio. People generally say the way to a man's heart is through his stomach, but I think it's definitely better to grab him by the ballsac.

I told this to Mika, and when she replied, "I see!" I suggested, "Then how about we study fellatio next time?" and it was decided I would teach her from square one.

She was a woman who went along with my story so conveniently for me, and because of her, I started to mistakenly believe that I could do whatever I wanted to women.

I was able to practice conversational brainwashing and guiding her thoughts, so this woman is the beginning of everything for me, 'Masaru'.

This time was mostly explanation, but from the next entry, there will be more sexual descriptions.

Mika (24) Gradual Brainwashing and Service Training

For the first month after making Mika my sex friend, I made sure to go to her apartment as close to every day as possible.

I'd stop by for even just 30 minutes, have her suck me, and then leave promptly whether I ejaculated or not. I repeated this to make it a given that when she saw me, she would suck my dick.

If she were a one-off, disposable woman, I wouldn't do something like this, but I wanted to use her for sexual release over the long term. It was a semi-experimental form of training, born from the thought of whether it was possible to have such a woman, wanting to slowly remold the inside of her head.

Once the 'chat 'n' suck' became a given, I gradually started to convey my own desires.

Since I had drilled into her that fellatio is skinship and an act done not for the man but for the woman, Mika, who had come to think that both chatting and fellatio were the woman's desires and that I was a kind male friend who was humoring her in both, was delighted when I started to show my own desires.

What I requested was a 'while-doing-something-else blowjob.'

The chat 'n' suck was Mika's version of a 'while-doing-something-else blowjob,' a way for her to relieve stress.

The consultation was: since Mika also enjoys her 'while-doing-something-else blowjob,' is it okay if I have one too?

Specifically, I told her that I wanted to do my usual things during fellatio, but "I've never done it because 'normal women' would hate it."

Every woman has a desire to be thought of as a special woman, different from the normal ones.

When you use the words 'normal woman,' it becomes easy to guide a woman's thoughts.

When I asked her, "I want to smoke cigarettes and play with my phone during the blowjob, but you'd hate that, right?" as expected, she appealed to me as an understanding woman by saying, "It's totally fine! I want you to relax, at least when you're with me."

After this conversation, I made it a point to always smoke.

Then, I gradually started to smoke earlier and earlier, until eventually a flow was established where I'd enter the room, immediately light a cigarette, and in the meantime, Mika would pull down my pants and start sucking.

I would purposely text her things like, "I want to smoke one cigarette, can I stop by?" and then really just stay for one cigarette (while she sucked me). I kept drilling into her that it was a given that she would suck me no matter what I was doing and that she wouldn't stop, so Mika, who used to be a woman whose jaw hurt after 10 minutes, at this point, became a woman who had no problem licking for 2 hours.

Around this time, her kids were still in daycare, so I made it a rule not to see her in the evenings.

Consequently, this was a period where the days I didn't ejaculate were overwhelmingly more common.

I think any man would understand that it's pretty tough to finish without ejaculating.

Why was I able to endure it? It's because I had become curious whether the method I used to make Mika fall would work on other women, and I had successfully captured another woman.

I'd have Mika suck me during the day, and have another woman get me off at night.

That woman was a 19-year-old named Shinobu.

(I'll write about Shinobu separately, and later on, Mika and Shinobu meet and develop a relationship where we have threesomes.)

So, I started to enjoy not ejaculating; in fact, I began to feel a strange excitement from the fact that the woman who makes the sperm and the woman who extracts it were separate.

Mika started to feel a sense of guilt for not being able to make me ejaculate, but this, of course, was also part of the plan.

If she can't make me ejaculate, she'll start to think that she wants to at least make me feel as good as possible, to satisfy me even a little.

That's when I teach her to lick my ass.

When she licks my balls, I make a show of twitching in reaction, so she learns that that's what feels good, and as she starts to lick for longer, I purposely stop reacting.

Then she starts searching for a place where I'll twitch while she's licking.

I time it for when she's approaching my perineum, and then I start to twitch again and make my breathing rough.

As if she's found it, she starts to lick earnestly, and when she's close to my anus, this time I purposely jerk my hips, feigning an accident, and make her lick my asshole.

I repeat that a few times to get her interested in my anus, and finally, when she starts to lick my anus persistently, I stroke her head and mutter, "You're the best woman."

With this, a woman who will willingly lick my ass is complete.

When I asked her later, she said she had never done that for any other man.

I want you to remember how Mika and I meet: I go to her room during the day, immediately light a cigarette, and Mika immediately starts giving me a blowjob.

In other words, I'm not taking a shower or anything.

And she's licking that asshole.

Whether it was because she was already sucking my dick, which could smell on some days, as if it were a given, she also licked my unwashed asshole as if it were a given.

Once she's come this far, she won't refuse anything I make her do, and a woman who will kind of do anything is complete.

By the time two months had passed, she started leaving her kids with the mom-friend in the next room on weekends in order to get me off.

Mika (24) and Kaori (25) A Woman Introduces Another Woman

Mika was on good terms with the family in the apartment next door, and since they had kids of the same age, they had a relationship where they would go back and forth between each other's homes.

On their days off, the husband next door would watch the kids while the mothers went shopping together, or Mika would look after their kids while the couple next door went out for a drink by themselves. It seemed they were living well, relying on each other. That couple's wife was Kaori.

When we were having our skinship at Mika's house, talk of Kaori often came up.

Things like how she was born and raised in Japan but her parents were Chinese, or how her husband had caught her cheating several times.

And recently, she had apparently said to Mika, "Your vibe has changed. Your skin is glowing, and there's a kind of calmness about you. Did you get a new boyfriend?"

Mika had apparently answered that it wasn't a boyfriend, but the influence of a male friend.

After being grilled for details, Mika explained that they spend a relaxed time together with skinship of the mouth, to which Kaori apparently leaned in and said, "I'm so jealous! I want to talk to that person!"

Kaori wasn't dissatisfied with her husband; she was just a person who believed in cherishing herself as a woman and seemed to have cheated just for a little bit of stimulation.

Mika, who understood that feeling well, came to me with a consultation: if I was okay with it, she wanted to invite Kaori over to her room to chat and stuff.

I was a little hesitant, thinking I didn't want to get involved with someone who could put my own life at risk.

I had her tell me not just about Kaori, but also about her husband.

Age, hometown, job—after confirming that we had absolutely no connection, I also made Kaori promise not to speak about me to anyone, and to pretend to be a stranger if we ever ran into each other by chance. Then I gave a tentative okay.

We decided to meet at Mika's house in the early afternoon on a later date, and there was something I had forgotten about until that day.

For some reason, I hadn't asked what Kaori's job was. When I went to Mika's house that day, Kaori was already in the room, but when I said "Hello" and saw her face, I was surprised at how much of a "gyaru" she was, something I wouldn't expect from a friend of Mika's. Immediately after that, I realized I had seen her somewhere before, and was surprised again.

"Huh? I feel like I've seen you somewhere before!" I said, and after the three of us talked for a bit, it turned out she was a clerk at a shoe store in a large shopping mall.

She was the woman I had thought, "She's a shoe store clerk, but she's dressed awfully erotically," several times when I passed by that store while shopping with my family.

When I mentioned that it took me a while to realize because her clothes were casual, she told me that at work, she's always conscious of wearing revealing outfits. She said it's because the store manager likes it, and she's less likely to get yelled at that way.

Then, after we had been chatting for about an hour, Kaori, with a smirk, brought up the topic: "Mika told me what you guys do here~."

I knew from before we even met that she was probably interested in that, and from the fact that Mika tried to set us up, I also knew that Mika wasn't against the idea of me and Kaori having skinship.

Before this day arrived, I had decided that the one thing I wouldn't do was come on strong myself.

Being seen as thirsty for women would leave the worst impression on both Mika and Kaori.

For Mika, I was an irreplaceable male friend that her female friends would envy.

For Kaori, I was a man who had an ongoing physical relationship with her friend, a man she might do the same with herself.

I had to proceed while keeping both of these images positive at the same time.

The moment the conversation turned from small talk to the core issue was the make-or-break point.

To Kaori, who had brought up the topic with a smirk, I didn't act shy, or troubled, or even smirk back. With a moderately gentle smile, I replied, "Oh really? Yeah, it's super refreshing ♪," and then sought Mika's agreement with a "Right?"

When a topic is suddenly thrown at you, you have no choice but to answer "Yeah."

I immediately followed up with, "Everyone feels stress in their daily lives, right? But cheating has a huge risk, right? Because you're married. Even if you're single, you don't know how long it will last with your boyfriend or girlfriend, and there's no point in consulting same-sex friends about that partner. That's why a male friend you can truly trust is soありがたい, right?" I threw it to Mika again.

Mika, flattered at being called a trustworthy friend in front of her female friend, got in a good mood and said, "It's so true. After we hang out, I feel so motivated about all sorts of things!"

Her words were her way of saying (I feel the same way) to my words.

My previous words had made Kaori feel:
A reflection on her past failures with cheating.
The necessity of a male friend.
And furthermore, a loophole in her own mind that "This isn't cheating."
On top of that, Mika's words gave her the added excuse of "This is something necessary to cherish my family!"

From there on, both of them started to reply "uh-huh, uh-huh," and "Ah, I really think so," to everything I said. When I told them my trauma story, they tried to get closer to me, saying "You poor thing!" and "Right?" and "That's why we can trust you!" and appealed to me that I was a special existence with "There's never been a guy like this before."

I had intended to take my time over several days, but since I had captured their hearts more smoothly than expected, I thought, maybe I'll go for the win? I said to Mika, "I can only stay for about two more hours, so I'm going to borrow your bath," and briskly headed to take a shower.

"Huh? Where was the switch again?" I said, calling Mika over, and whispered in her ear, "After I get out of the bath, I want you to start sucking me in front of Kaori as if it's the most normal thing in the world while we make casual conversation, got it?"
"Okay," Mika replied.
