My Best Friend's Wife (Transformation Series Adult Novels)

(1)

"Naoyuki-nii, are you interested in spouse swapping?"

I got really scared when that guy suggested this, but he looked serious and didn't seem like he was just kidding. Although I have heard of such things before, where two couples exchange partners to have sex, this is the first time I have actually encountered someone proposing this.

If the other party had proposed it jokingly, I would have definitely rejected it on the spot; but the atmosphere at that time made me ask for a little more time so that I could go back and think about it carefully.

"Then please go back and discuss this with Miss Kanako. I look forward to your answer."

The other party’s suggestion about exchanging spouses after we broke up is still fresh in my mind. I calmed down and thought carefully, were these words true? Is it fake? What does it mean for the other party to make such a suggestion? My heart is filled with incredible feelings.

My name is Naoyuki Omatsu, I’m 45 years old and I teach in an elementary school. Nakaichiro Kimura, who made the proposal today, is my best friend since elementary school. Our families have close contacts, and even after we got married, we still live in nearby communities and continue to maintain a good friendship and interaction. But why would he come up with such a suggestion out of the blue?

My best friend and I are the complete control group, both in terms of personality and appearance, but that's precisely why we have had a particularly good relationship over the past few decades. Compared to that flower-like man, I have an ordinary appearance and a short and fat body. When I went to the hospital, the doctors laughed and said that I was a typical patient of "metabolic syndrome".

My best friend has always been popular since he was young. If you want to find someone to be the standard example of the word "handsome guy", he would be the right one. He is also well-received for his interpersonal skills, which makes him, who is already smart, very successful in society. My best friend, who is engaged in the import and export of precious metals, recently bought a single-family house in a high-end residential area, while I am still stuck in the teacher's dormitory which is like an ant's nest.

Want to swap wives with me? The woman in my family was my classmate when we were trainee teachers in elementary school. We were the only two single young teachers in the school, and as time went by, it seemed natural for us to get married. But she - how should I put it - it felt like she had married an elementary school teacher rather than a wife. After work, she couldn't even think of her identity as his wife, and she still treated me like a student and educated me strictly. When they were dating, Kanako was still considered a "simple beauty", but since giving birth to her daughter Asuka, who is now in junior high school, her weight has been increasing like a balloon. Now when we take a walk together, I can completely hide behind Kanako's back.

Although other people's wives are always better, no one was surprised when his best friend, who already had a lot of romantic opportunities, decided to marry Misa, a recognized beauty. With her tall and slim figure and the fact that she has never had children, many people would believe if someone said that Misa was a female college student who had just started working, even though she has been married for ten years.

"Trade Diao Chan for a sow? Are you kidding me?" I have known Kimura-kun for decades, and I can tell from his eyes when he spoke that he was making the invitation sincerely, but what's the good of me and my woman? Will it make them want to swap spouses with us?

(2)

I tossed and turned the whole night. When I got up, I didn't tell my wife what I was going to do. I went straight to my best friend's house to find out everything. This matter cannot be decided by just the two of us men. We have to consult Misa's own opinion. To me who lives in reality, what I said yesterday was even more exaggerated than just talking in a dream, and it is not the first or second time that Kimura has played pranks and jokes on me over the past few decades.

"You idiot, I must be joking," I thought to myself, looking at my best friend couple sitting in front of me, eagerly hoping to hear the answer I wanted from them - the result surprised me.

"We haven't had sex for a long, long time," my best friend said shyly and a little embarrassedly. "Naoyuki,
How are you? Between me and Kanako? "

When this familiar couple in front of me suddenly asked me this, I was at a loss as to how to start. Although Kanako and I sometimes quarrel, we live a normal married life and enjoy watching our daughter grow up every day. To be honest, although our sex life is not as frequent as when we were young, it is still normal. As for the idea of ​​"swapping spouses", it is something I have never thought about at all.

I honestly told my best friend couple that although Kimura-kun mentioned the idea of ​​spouse swapping to me, I actually thought it was only a temporary solution and not a fundamental solution. Although it may help the relationship between husband and wife for a while, it is not a long-term solution. I seriously hope that the couple will reconsider this.

I looked at Misa and said, "Do you really think this is okay?"

"Well, my husband and I have the same idea. From now on, I hope you and your husband will take good care of me."

“Ugh…”

I looked at Misa, who was sitting next to her best friend and bowing deeply with her head bowed. Her beautiful ears and neck made me suddenly feel a throbbing sensation and I got an erection without realizing it. Being able to hug such a beautiful woman is something I have never experienced even in my dreams.

Now that the other couple's attitude has been confirmed, the next problem is Kanako's side.

If such an immoral suggestion were directly raised to her, she would probably fly into a rage. Thinking about the promise I made to my best friend and his wife, I am at a loss as to what my future relationship with her husband will be like.

Ah, it seems that I can only keep my head down as much as possible and ask my wife to make the decision. But to be honest, helping best friends is just a superficial reason. The most important thing is to take care of your own interests. What should I say to Kanako?
How should I answer? I kept pondering it in my mind. Asuka's school is going on a trip this weekend, so I'll take this opportunity to give it a try.

When I got home in the evening, after making sure Asuka was asleep, I timidly proposed the Kimura couple's suggestion to Kanako, but I didn't expect Kanako to agree readily. For me, the idea of ​​swapping spouses was something I had never even thought about, and I was surprised that Kanako agreed so easily.

"Hehe, it's because the other party is the handsome man Shinichiro." I deliberately joked to hide my complicated feelings, but three of the four parties involved agreed, and I didn't even have a chance to back out. So we agreed to limit it to just one time, on Saturday night.

That day, the four of us first met at a best friend’s jewelry store, then had dinner at a restaurant and then went home. Kanako was so excited when she woke up in the morning that she kissed me after lunch and said, "
Husband, you absolutely cannot back down now." She put on makeup carefully, which was unusual for her throughout the afternoon, and then she even took out some sexy brand-name underwear. My eyes widened in shock, I couldn't believe that an elementary school teacher would dare to wear such underwear.

After everything was done, Kanako walked up to me gorgeously and happily spun around to show off her outfit. well,
It’s a good thing for me that my wife, who is always hysterical, is in such a good mood. Maybe it would be nice to exchange with each other occasionally in the future, but we'll have to wait until after tonight.

After arriving at the jewelry store, Kanako's best friend insisted on giving her a piece of jewelry as a thank you gift in order to thank her for her help. Oh no, I didn’t bring anything with me and my hands were empty. I felt so embarrassed towards Misa. Kanako's face was filled with smiles, and she looked like she was about to jump over and hug her best friend. Thinking of this, I wonder if my best friend really wants to hug Kanako like a sumo wrestler.

After finishing her meal at the high-end restaurant, Kanako went back with her best friends, while Misa and I returned to the small and crowded faculty dormitory. Thinking of this, I once again felt very sorry for Misa. Misa was holding a large bag, and I didn't know whether it contained spare clothes or skin care products for night use.

What to do next when you get home? The atmosphere was a bit awkward at the beginning, and the two of them just looked at each other silently.
Misa was the first to break the silence and suggested that they take a bath together. When Asuka was a child, our family of three would squeeze into the bathroom to take a bath together, but after that, we have never taken a bath with a woman in all these years. While waiting for the bathroom to warm up, I took a can of beer from the refrigerator and we shared it. After a few sips of alcohol, I wasn't as nervous as I was at the beginning. Looking at Misa's expressionless face, a thought suddenly flashed through my mind: I wonder what Kanako's current situation is like? When it comes to things like this, it seems that women are more mentally prepared than men.

(3)

By the time the two of us squeezed into the cramped bathroom, I was already fully erect. Misa's body, which had no fat at all, had a pale pink color that seemed to symbolize shyness. Seeing my erection, Misa squatted down without saying anything and carefully helped me clean my penis and glans, while constantly stimulating various vital points of my little brother. I could only moan as my little brother was being taken care of so vigorously by a mature woman in her thirties, and in my heart I kept muttering thanks to the gods in heaven for giving me such a great opportunity. How will this spouse swapping thing change Kanako's and my life? I kept thinking.

After washing the front, Misa carefully cleaned between the legs all the way to the anus, but at this moment I said something that spoiled the mood.

"I'm sorry, I'm about to cum..."

Standing on high ground and looking down at Misa's beautiful face and well-proportioned breasts, the defender of Jingguan was ready to abandon the city and flee. But Misa didn't seem to be affected at all and gently helped me clean my penis.

“Ah…ah…this…”

If I ejaculate now, wouldn't I ruin this hard-earned opportunity for orgy? I asked Misa to stop her ruthless hands, but unexpectedly she added even more violent force.

Not only did she rub my penis hard, but her other hand also went around my butt and rubbed my anus. I can’t bear it anymore….

"sorry……."

I was so terrified that I didn't know how to apologize, but Misa helped me wash off the semen while using her other hand to stimulate my butt and scrotum alternately. The penis recovered amazingly quickly in Misa's hands.

"Eh? Is it really okay?"

"Ah...yes, thank you so much..."

I responded to Misa's words foolishly, while desperately trying to figure out if there was something wrong with me. Fortunately, she didn't seem to care.

Misa's next action after coming out of the bathroom shocked me again.

"Mr. Naoyuki, are you okay?"

"OK!"

I played with my penis, which had become erect again due to Misa's anal stimulation, and tried to regain my confidence.

"Please don't be scared by my interest..."

Although I was a little scared by Misa's superb skills in the bathroom just now, I still said it was okay.
She then took clothes out of a big bag and put them on. My eyes grew bigger and bigger, like a mink's.
Misa put on a high school sailor outfit.

"Do you hate me wearing this?"

"No... no... very good..."

To say that Misa, who is already over 30, matches the super short sailor uniform is definitely not a compliment, especially since there is probably not a single man in Japan who hates sailor uniforms. The tall figure and plump flesh made the small sailor uniform look indescribably charming. I could almost hear the sound of blood rushing in my penis which had just recovered.

"Well...if you don't mind...I have one more favor to ask of you..."

Misa's next words almost made me bleed from my nose like a high school boy.

"Can I masturbate in front of you?"

I didn't dare answer. Misa first sat cross-legged. She was not wearing a bra under her shirt, and her two nipples were clearly protruding from the fabric. When her body twisted, her plump breasts were tense, and the buttons seemed about to burst. Misa began to pant sadly. She lifted up her miniskirt to reveal her real white cotton panties for high school girls. She put her fingers along the waistband and rubbed her honey meat in front of me.

“Ahhh! It feels so good~oooooooooooooooo!!”

Misa's voice is usually very pleasant to the ear, but I didn't expect her moans to be even more alluring.

"Can you please, Naoyuki-san, masturbate in front of me?"

Normally, due to my phimosis problem, my foreskin cannot slide out immediately, but due to a series of unexpected events, the entire glans actually jumped out by itself. I ejaculated again while Misa continued to moan and moan.

Sigh... Why is this happening? Considering my age, ejaculating twice a day is already considered reckless behavior. The amount of semen decreases significantly. Just as I was regretting my foolish behavior, Misa reached her climax and screamed loudly.

"Naoyuki-kun, are you an S or M?"

While she was hesitating, Misa took out the handcuffs from her bag. I have never played this kind of thing with Kanako, but I think if they handcuffed me, I would definitely resist. I made my attitude clear

After that, Misa said that she would be handcuffed later, and then took out some props from the bag. After I handcuffed Misa's hands behind her back as instructed, I helped her put a blindfold on her, had her lie down, and gently brushed her entire body with a brush.

As the tip of the pen crawled, Misa moaned loudly and twisted her body. Unable to bear the stimulation of the obscene scene before his eyes,
The little brother actually stood up for the third time!

"Misa, I'm hard again..."

"Please... Please treat Misa well..."

This is not a dream… This is really not a dream…. I roughly turned over Misa's body and forced my penis into her little mouth. With coughs and groans, I exploded in her mouth for the third time. Then I inserted the forked massager into Misa's vagina and anus at the same time, and used a vibrator to play with her nipples and clitoris, sending Misa to the unparalleled climax two or three times in a row.

"Mr. Naoyuki, come here, please use your big cock to fuck Misa to death!" The woman cried and howled, and she could no longer tell whether she was in pleasure or pain.

I used tape to fix the vibrator on her nipples, inserted the massager into Misa's anus, lifted up her long legs, and thrust my penis straight into her flower heart.

Finally I ejaculated for the fourth time...

I was awakened from a deep sleep at noon by a strange soft touch. Misa, with her hands still cuffed, had her back to me.
The soft buttocks pressed against my face,

"Please, good man!"

Hearing her lustful moans, my desire was aroused again.

"Please give me one more chance..."

Under the woman's constant seduction, we shared one last pleasure. Misa assured me that she had taken birth control pills and asked me to finally shoot my already thin semen deep into her uterus. After helping Misa remove the handcuffs, she began to talk about her special sexual preferences. At first, my best friend was also deeply fascinated by this compulsive sexual behavior.
But after a long time, the enthusiasm can no longer be rekindled. So in the end, Misa asked her best friend to mention the idea of ​​couples swapping to me.

"Did I perform well?"

"Well, compared to my husband, yours is really huge, Naoyuki-san. I almost couldn't handle it..."

Although it was probably just a social gesture, it still made me a little happy.

We finally parted with a long, deep kiss.

Kanako, who just came back in the evening, had a good mood written all over her face.

"Does Shinichiro really like a super-sized aircraft carrier like you?"

"I took everything he said all night as social etiquette, hahahahaha!"

Haha, I seem to have heard similar dialogue somewhere. In a relaxed mood, I asked my wife some dirty questions, asking her to compare who was better, Shinichiro or me. My wife had a strange and seductive expression on her face, she smiled but didn't answer.
Just say that they also used handcuffs, and that it really aroused my wife's sexual fantasies.

"Well, how about we try it out as well?"

"So they handcuffed you?"

"Idiot, I'm going to cuff you!"

It seems that the best friend was given a good lesson after being handcuffed by Kanako. Alas, now I can’t even figure out who is the S and who is the M between my best friend and his wife. But no matter what, I got excited when I thought that this brat Kimura would actually let my sow be handcuffed.

The spouse exchange happened just as agreed upon, and there was no second time. After that, the two families continued to interact as usual, and the hidden tension between the couples in the two families seemed to have improved. The only change was that Misa was pregnant. My best friend said that we were all on contraception at the time, so she asked me not to worry.
But I still secretly wonder if my best friend has some physical problem and deliberately swaps couples to ask me for sperm. I still often have the evil thought that it was my sperm that made the beautiful Misa pregnant. I was excited thinking that Kanako's huge ass would ride on my face again tonight, and I would be forced to give her a blowjob with my tongue while almost suffocating.
I felt extremely happy as her fat fingers dug into my asshole and squeezed out my semen.
