In the dimly lit room, only a pink neon light hanging from the ceiling dimly illuminates the area. In the silence, the only sounds that linger in my ears are the heavy breathing of the two of us and the lewd splashing of water. Eventually, we exchange glances, and with a mischievous smile on her face, Reika slowly leans closer and whispers seductively in my ear, "Mmmm ❤️… How does it feel…? ❤️"
"—Ah, huh?! Reika!! It's coming already…?!" I stammer.
Reika, straddling me in a cowgirl position, was making me ejaculate right from the start with her skillful, seductive hip movements and the squeezing of her vagina. All I could do was endure it, clenching my molars as hard as I could and stretching my legs out, trying to hold on for as long as possible, but…
"Come on, just cum inside me ♪❤️," Reika teases.
"—Uh, aaahhh?!" I gasp.
The sudden, intense stimulation makes my whole body jump. I looked over and saw Reika with a sadistic smile on her face, lightly pinching my right nipple. A sweet yet bitter pain sends an electric current through my brain. My whole body twitches and convulses as if I had just ejaculated.
I recently started "nipple development" for a certain purpose. The effect was more powerful than I had expected. One moment she scratches my nipple with the tip of her nail, and the next moment she uses the pads of her thumb and index finger to pinch and rub my nipple. The stimulation is just right—not too painful, but not too weak either. The exquisite force exerted is so precise that it's as if the nipples themselves are likened to sexual organs, and it's hard to believe that it has only been in development for less than a month.
While I was secretly amazed at my girlfriend's unexpected talent, I was also reaching my limit. As my embarrassingly erect nipples were being rubbed, I felt something hot like magma rising up in the pit of my stomach. I was writhing in agony like a woman, as my nipples were stimulated with such sweetness, but then suddenly, a whisper in my ear and the intense stimulation of my nipples being pinched tightly made my lower body, which had been holding back to its limit, finally give way.
"—Come on, come on, come on♪❤️," Reika urges.
"—Ah, ah, ah, aaaahh… —Whirl, whoosh, whoosh…"
Squeezing tightly❤️, squeezing❤️, Reika's vagina gripped me as if squeezing me, and I came easily and pathetically through the condom. The stimulation to the nipples was intense, but the pleasure it gave to my penis as it was squeezed so tightly that it squeezed out every last drop was even greater. After ejaculating for a surprisingly long five seconds, which is unusual for me, I look up at the ceiling in exhaustion, as if I've released everything.
As I was staring blankly at the ceiling and the pink neon lights that looked bad for my eyes, like I was in a daze, a close-up of Reika's happy-looking face suddenly came into view. "Today, it seems like you were able to go all the way to the end for the first time in a while…!" she said.
"…Yeah. I guess it's all thanks to Reika telling me that story before we played…" I replied.
"…Uh, well, I'm not really happy about that… but, it's not just that this time, is it…?" she asked.
"Uh, th, that's…" I stammered.
"You were harder than usual because you were imagining what was coming up next, right?❤️" Reika teased.
"S-sorry, Reika…" I apologized.
"…Yuu, you're such a pervert after all…❤️" Reika said with a slightly dissatisfied look on her face, then, as if to regain her composure, she forcefully took my lips.
I let myself go and let Reika devour me. Even as we felt the sensation of our tongues parting our lips, we both breathed heavily as we entwined our tongues with each other's. After a long, happy deep kiss, Reika slowly released her lips with a satisfied look on her face. As our lips parted, our bodily fluids mixed together, forming an obscene bridge of thread.
"But I want to do anything for Yuu… I wonder if this is the weakness of someone who is in love…?❤️" Reika said softly.
"…Um… Thank you so much, Reika," I replied.
"Hehe, you're welcome…❤️" she said with a smile.
Reika straddled me, pushed me forward, pressed her soft breasts against me, and sweetly asked for another kiss. The soft feel of a woman's body and the sweet, peach-like body odor that wafted faintly from Reika's entire body once again aroused a part of my body.
"It's gotten a little hard again…?" she noticed.
"…Yeah," I admitted.
"Shall we do this again…?" she suggested.
"…No good, I need to change the rubber…" I said.
"I don't mind if it gets torn though (lol)❤️," Reika said with a seductive smile on her face and began to play with my nipples again with her fingers.
Even though I was in sage mode, I couldn't help but let out a cry at the sweet, tingling sensation. "…Ugh!" I gasped.
"…Hehe, Yuu is really a masochist… (lol)❤️," Reika teased.
"…You already know that for a long time, right…?" I replied.
"That's right❤️… After all, you're a total perverted masochist who gets excited by something like that, right…? (lol)❤️❤️," she said playfully.
"Ah, ahhh?!" I exclaimed.
When I complained, Reika gave me a mischievous smile and started playing with my nipples again. She rolled the nipple between her fingers, rubbing it up and down to increase the stimulation. Gradually, I began to feel more and more pleasure, and my penis became hard again inside Reika's vagina.
"It's been a while since we last did this, so I'm going to have fun today♪❤️," Reika said.
"Didn't we just do it a few days ago…?" I asked.
"…I wasn't able to fully satisfy myself then… If it were true, I'd want to have sex with you every day!❤️❤️," she declared.
"Ugh, th, that's not right…!" I protested.
With a grin like that of a carnivorous beast, Reika whispered a truly seductive declaration in my ear, then began her lustful predation on my waist again.
…
After two more rounds, I took a shower to refresh my sweaty body and then returned to my room. Incidentally, Reika had already finished showering before me. Right now, she's probably bored and playing with her smartphone.
Thinking about such things, I returned to my room from the shower room, and Reika, who should have taken a shower before me, was still completely naked, with only a bath towel wrapped around her from the chest down. My eyes met with Reika, who was sitting on the bed like that, but… I felt guilty now and turned my eyes away from her with an embarrassed look on my face.
Usually, around this time, we would be having some intimate pillow talk in bed before taking a shower, but today we had both quickly finished our showers. For some reason, we both rushed to get ready this time, and perhaps because of that, there was not even a trace of the usual sweet atmosphere between us.
"..." I said nothing.
"..." Reika was silent too.
I had already changed and was ready to go home, while Reika was still sitting on the bed in just a bath towel. The two of us, dressed so mismatchedly, didn't know what to say to each other, so we just sat in silence and listened to the clock ticking away. When I thought about the plans for the rest of the day, I got so nervous I couldn't speak. Or rather, I had no idea what to say to Reika in this situation. If I didn't bring it up, the front desk would soon call to confirm whether I wanted to extend the stay or settle the bill.
Just as I was concerned about such things, the phone in the room started ringing with a beep, beep, beep, like an alarm. Startled by the sound, I involuntarily turned toward Reika. It seemed that Reika was looking at me as well, and my heart started when our eyes unexpectedly met. A moment of silence passed between the two of us, with both ignoring the phone ringing, but then Reika spoke nervously, as if to confirm something for the last time.
"…Hey,… is it really okay?" she asked.
"…" I couldn't find the words.
My heart was beating fast as if it was going wild. Unable to find the words, I managed to nod awkwardly, and Reika, with a somewhat complicated expression on her face, picked up the phone that had been ringing nonstop.
"…Yes,… yes, that's right. —Yes, please extend the time…" Reika said clearly over the phone, requesting an "extension."
Reika put down the receiver and checked her smartphone, then frowned slightly, looked confused, and spoke with a blush on her cheeks. "…He's already waiting in front of the room…"
"Hhhh, I, I see… I, I guess I should, I should get going soon…" I stammered.
"…Yeah," Reika replied.
Reika looked away awkwardly, as if she didn't want me to see the expression on her face. My heart fluttered at Reika's attitude, which I'd never seen before… she seemed slightly embarrassed, but I gathered my belongings and headed alone to the entrance of the room.
"…As promised, I'll be back before midnight…" I said.
"…Yeah… I'll wait until you come back," Reika replied.
Pretending not to notice the loud pounding of my heart, I told Reika over my shoulder, unlocked the door, and went outside. Then, leaning against the wall right next to the door, a voice called out, "Hey, Yuu! Are you done yet?"
"…Takumi," I responded.
The man who greeted me with a smile and a raised hand, acting just like normal, was one of my few friends from university, Saijo Takumi. He had dyed his natural wolf hair a brown that leaned toward blonde, and he had a very frivolous and light-hearted look, as evidenced by the earrings in his ears and the men's necklace with a ring hanging from his neck. However, contrary to his flashy appearance, as can be seen from the bright smile he gave me, his personality of treating everyone equally makes him very likable to others. Even though he is a playboy, he has a likable personality that makes it hard to hate him. For me, Takumi is one of only two same-sex friends at university that I can confidently say I am close to.
And so, I made a "certain important deal" with Takumi that would last just that day. "I'll just confirm this one last time, is it really okay for you to go all out?" Takumi asked.
"…Uh, yeah. That's the promise…" I replied.
"I see, then I'll go ahead and do it this time!" Takumi said with an innocent smile and slapped me on the shoulder.
Then, with a delighted smile on his face, Takumi took my place, his expression stiff, and entered the hotel room we had been staying in just a moment ago… That's right. So that he could embrace my future lover, Kujo Reika…
"Hey, Yuu!!" Takumi called out.
"What?! Wait, stop it!" Reika's panicked voice followed.
As I stood there frozen in place, I heard Takumi calling out to me from behind, followed by Reika's voice. When I turned around, I saw Takumi holding Reika close and squeezing her breasts, and Reika, her face red and squirming. Seeing that sight, my heart involuntarily skipped a beat loudly.
"That's what I'm saying, isn't it? Takumi will be happy if we show him off like this," Takumi said.
"But… why would you go out of your way to do something like that right in front of Yuu…" Reika protested.
"Hey, Yuu! Once you've burned it into your memory, close the door of your own volition (lol)," Takumi said with a laugh.
Takumi laughed, and unlike usual, his laugh was unpleasant, as if he was making fun of me. He's already flipped the switch. Takumi had explained the situation to me beforehand. He was just putting on a show to get me more excited. He's a veteran, and he knows what words and actions will most arouse my jealousy and excite me, so he actually plays the role of the nasty adulterer.
And just as he had hoped, the sight of my girlfriend's breasts being squeezed in front of me made my penis, which had ejaculated to its limit just a moment ago, harden again.
—Cuckold fetish. That is the name of the twisted sexual fetish I suffer from. Being excited by the idea of one's spouse or lover being taken away by another person… This is extremely perverse for a creature whose first priority is the preservation of its own species, and it is one of the shameful sexual fetishes that only those who have gone astray can have. An abnormal sexual fetish that is so minor that it will never be understood by the general public. What would be a traumatic and humiliating experience for an average man can sometimes be the greatest excitement for someone with a cuckold fetish.
I've always been a masochist, and even before I started dating Reika, I had been into cuckold games and doujinshi to some extent. However, I only saw it as one of the "materials to get off to," and it wasn't a genre that I had any particular attachment to. However, after many twists and turns and ending up dating Reika, due to various factors such as inferiority complex and jealousy, I developed a "cuckold fetish" that was not fiction but reality.
Until recently, I had been suffering from erectile dysfunction to the point that I was no longer able to hold my girlfriend, Reika, in a normal manner—a condition known as ED. Naturally, I was anxious and started looking for various solutions to my ED. I continued to search the internet and books for information and also consulted with my girlfriend, Reika, to find situations that would excite me. However, as expected, improving ED was not that easy.
And so, after finding myself in a desperate situation and going through many twists and turns that are too long to recount here, I finally arrived at the solution of "consensual cuckolding" with a partner I could trust. And the person I chose to trust was Takumi, the person in front of me and my only friend at university. Reika had felt reluctant to sleep with a stranger but reluctantly accepted the "cuckold play" since Takumi was an acquaintance.
"…Is it really okay?" Reika asked.
"…Uh, yeah… I don't mind…" I replied.
"…I understand… If you say so, Yuu," she said.
As Takumi pulled her close and fondled her breasts, Reika blushed as she made a final confirmation. Seeing Reika like that, I felt a painful erection, but I nodded awkwardly. Seeing Reika lower her head in embarrassment at my response, I swallowed hard and put my hand on the open door as Takumi had told me to. By closing this door, I would be announcing the start of my first-ever "cuckolding" experience.
"—Ah, that's right! As of now, there are no plans to extend the session beyond the first session, so I think we'll be able to return Reika before the date changes," Takumi said.
"…Yeah, I understand… Well, then, well, I'll be happy to help you…" I replied.
"Yeah, look forward to it!" Takumi said with a grin, raising one hand in greeting.
For some reason, I felt awkward now and couldn't look Reika in the face. And so, without speaking to Reika until the very end, the door slowly closed.
"..." I stood in silence.
"...Ah," Reika let out a soft sound.
On the other hand, Reika, still in Takumi's arms, glanced at him once but quickly looked away without saying anything. Seeing Reika in that state, I wanted to say something immediately, but in the end, my words didn't reach her, and the metallic sound of the door to the room closing echoed throughout.
"…hhhhhh," I exhaled, holding back the pounding in my chest with my hands.
Regret began to well up in my mind. But more than that, it was true that I felt more excited than I had ever felt before. Letting my beloved sleep with another man and then later asking her to tell me about it—this causes me to feel great sexual excitement in exchange for jealousy, humiliation, and all sorts of feelings of defeat as a man. For those who have become fascinated with the perverse sexual fetish known as "cuckolding," this becomes a kind of drug that brings them the most blissful pleasure of all.
"…Let's go home," I muttered to myself.
After a short pause, as promised, I started walking toward the apartment where Reika lived. The current time is 7:30 in the evening. If Takumi was to be believed, I should be able to meet Reika again within the next five hours. I'm sure I'll be left with these agonizing emotions and excitement for a long time until that time comes. With this premonition almost like certainty, I took one step after another on my way home.
—This is the story of me, a dull otaku who miraculously managed to get into a relationship with a "gal who's kind to otakus"… But still, due to my own twisted sexual inclinations, I end up letting my best friend steal my ideal girlfriend…
