Part ⑦Witnessing Lover Cheating ☆
"---..."
It was a miracle that he didn't cry out. Or maybe once shock has passed, a person's thinking becomes rigid. Jin had found that out for the first time in his life. Though he didn't want to know.
To his right, near the lockers.
A man in a suit.
A woman in a shrine maiden's outfit.
They were embracing each other, devouring each other's lips.
"Chu, Nmuu♡ Nchuuu♡ Chu♡ Chuu♡"
The woman with her arms around Koichi's neck, standing on her tiptoes with a pout on her lips, was unmistakably, unmistakably Yui.
She was much more aggressive than when she was with Jin, pressing her huge breasts against Koichi's chest so hard that they changed shape, and entwined her tongue with his. She sucked. He was also in Koichi's embrace, and she had her eyes closed in bliss.
And in a daze, Jin just continued to stare intently at the kiss between his lover and his comrade. There was no doubt that it was consensual.
For a few minutes after Jin discovered them, they engaged in deep kissing. They seemed to only have eyes for each other.
Finally, their faces parted. It was definitely Yui and Koichi.
"Geez... in a place like this..."
Yui was dissatisfied, but she didn't look completely opposed. She showed no sign of loosening her arms around Koichi.
"Maybe it's because we're at work that it gets me excited."
"Really?"
"You'll see if you try it."
"Aah."
Koichi lightly bit Yui's earlobe, and Yui shivered. It was an affectionate expression that Jin had never done before.
"I'm counting on you."
Koichi whispered in Yui's ear, and Yui nodded.
Koichi sat down heavily on a nearby metal chair. It was a rare and very arrogant attitude for him. His behavior in front of his captain, Yui, could be considered rude. However, Yui herself showed no sign of paying any attention.
Instead, she bent her knees and sat on the spot without touching the bottom to the floor. Yui's face was now exactly at the same height as Koichi's crotch.
Yui unzipped Koichi's trousers with her own hands. It looked like a practiced technique, but was he overthinking it?
"!"
Koichi's male organ appeared with a thud, as if taking in some fresh air. What surprised Jin was that it was twice as large as his own penis when fully erect. And yet, it still seemed like it wasn't fully awake.
Jin's body was frozen, unable to move. Just like in that nightmare, all he could do was watch.
Please stop, please make it a mistake--his plea was not granted, and Yui's face moved closer to Koichi's male organ.
"Chuu"
Then she gently kissed the tip of the penis. Jin still couldn't move. Meanwhile, the act continued.
After greeting the penis, Yui opened her mouth wide, in a way that was indecent for a shrine maiden.
"Aa--muuh"
With a single gulp, Yui took Koichi's thing into her mouth. There was no hesitation. The thickness of the rod was clear even from Yui's deforming cheeks.
"Njyuu, muchuu, chuu, chiyuuu~"
Yui sucked the penis with a sound. Then she wrapped both hands around the scrotum, gently stroking it up, tracing the penis with her fingertips.
"Mujyuu, muchuu, mujuyuu, njyuuu"
This time she shook her head and began to stroke the penis with her mouth.
It was clear that she was not being forced, but was giving it a blowjob that she would only give to someone she loved.
"Good, Yui... feels good... keep it up."
Koichi said in a daze, perhaps from the joy of making the captain serve him. He patted her head and praised her, and Yui's eyes drooped in delight.
"Jiyuru ~, jiyurururu ~, njuu ~, muchuu , chyuu ~"
Yui's oral service became even more intense. Koichi's cock seemed to be getting even bigger. Yui looked up at Koichi while giving him a blowjob, like a loose-headed woman fawning over a man, a sight that was hard to imagine coming from her usual dignified self.
--It was very similar to the scene he saw in that nightmare. No, it was even worse.
"Fuaa...Muu"
Koichi moved his hips, and his penis was pulled out of Yui's mouth. Koichi's erection was shiny and black with Yui's saliva.
Should he take advantage of this gap?
Even if he did, what could he do?
While Jin hesitates, the next act begins. Or rather, it may be that nothing is broken between them.
Without any instructions, Yui loosens her obi and opens up the white shrine maiden robes.
Jin swallows hard. Jin doesn't know what's underneath either. He has only ever touched her through her clothes. Her precious, maiden chest.
A black, frilly bra is revealed. It is small compared to her bust, which is over 90cm, revealing a lot of her chest skin. What's more, the fabric contains mesh, making it a very provocative piece of lingerie. He is beginning to see a side of Yui that Jin has never known before.
"Oh, this is the first bra I've seen. Did you buy something sexy like I told you to?"
"I-I'm so embarrassed."
"It's fine. It suits you so well."
"What do you mean?"
"It's perfect for sexy Yui."
Koichi spoke as if he'd seen it countless times. And what's more, had he ordered Yui to buy it? Since when had the two of them become like this?
Yui blushed, but without hesitation he reached both hands behind his back. Without a sound, the hook was undone.
"--!"
Jin wanted to scream, but his vocal cords were frozen and wouldn't work. His eyes were glued to Yui's voluptuous bust. It was far larger than those of the three subordinates he'd seen in that nightmare, and was full of adult charm.
Even without the support of her underwear, her watermelon-like huge breasts were not giving in to the effects of gravity. It must have been the result of training. Her areola was a nice size, a light pink color, and the nipple in the center was fresh. Jin was a man too. He wanted to touch her. He wanted to squeeze her directly. He thought she would be his.
Now those breasts were facing another man.
Yui got on her knees, supported her chest with both hands, and squeezed Koichi's penis between her cleavage. Koichi's son was so enraged that even Yui's huge breasts couldn't contain it, and the tip of his glans was sticking out. Yui then applied pressure to her chest from the side, stimulating his penis.
"How's that...? Koichi, are you happy...?"
Yui's titjob wasn't intense, and although it was a little awkward, there was no doubt that the breast pressure was sufficient. Above all, it was breast service from Yui. There was no way Jin wouldn't be happy. It seemed the same for Koichi. But he wasn't happy at all.
"Of course. You're doing it just like I taught you. You can put in more pressure."
"That's good...♡ Got it, I'll try my best...♡"
Yui continues to service her breasts with a sweet voice. She applies pressure from various angles, squishing and squishing, and each time she does so, her large breasts change shape obscenely. There was no trace of the usual sharp captain there.
Yui's offensive doesn't stop.
She makes a squishy sound as she spills the saliva that she has been saving up in her mouth onto the protruding glans. That alone is lewd enough, but the saliva that has been collecting in her cleavage makes it even more lewd.
"Amuu"
Yui takes the glans, covered in saliva, into her mouth again. As she sucks, she squeezes the penis between her breasts to stimulate it.
"Kuoo..."
"Njuuu♡jiyururu♡ jiyururururu ♡jiyururururururu♡"
"Oh, that was good, Yui... Yui..."
Koichi, who had been relatively calm up until then, now had an ecstatic look on his face at this titty fuck and blowjob. His penis, which he thought was already at its limit, seemed to swell even more inside Yui's mouth.
The moment of ejaculation came easily. He was surprised he'd lasted this long.
Yui's mouth left his forehead for a moment, as if to take a breath.
--Brrrrrrrrrrrrr!
A tremendous amount of milky white liquid was released from the tip of his penis. Naturally, the semen fell on Yui's face. His mouth, the bridge of his nose, his hair - even the hair ornament Jin had given him - was all soiled with Koichi's seed.
"Wow, it's beautiful. Are you sure? Thank you, Jin!"
Yui smiles when he musters up the courage to give it to her as a present.
"--Yeah, I like you too."
Yui accepts his confession while still holding the hair accessory in his hand.
"I love you, Jin."
All of his memories are tainted with Koichi's semen. It's as if they're being smeared and hardened. At the same time, Jin's heart is covered in despair.
Yui didn't avoid the semen at all.
Aside from his face, the semen that was supposed to fall on the floor is caught by Yui's breasts.
"Aah, it's hot...♡ It's so thick...♡ Kuchuu, nchuu♡"
She sniffs the semen in a childlike tone and licks it off her lips. She doesn't hesitate to drink it.
"You like it thick, right? I've been saving it up, so you should be grateful."
"...Yeah♡ Thank you, Koichi♡"
Yui innocently thanks him even though she's been soiled. She's usually clean and serious, but if the office is even a little dirty, she'll give you a scolding. She's like a completely different person.
Her face, covered in white liquid, exudes both lasciviousness and innocence, bringing out a charm of Yui that Jin had never known before.
"Yui, sit there."
Koichi's orders don't end there. Yui obediently sits on the desk as she's told. It's unclear who is the captain.
"--- oh."
This time Koichi bends down, and the upper half of his body disappears into Yui's scarlet hakama.
The voice that seeps out of Jin's mouth is drowned out by the cold air of the hallway. The two are so engrossed in each other that they don't notice Jin's presence. Even if he had spoken louder.
"You're already wet even though I've barely touched you."
Koichi's mocking voice could be heard.
"Just a kiss and servicing me is enough to get you excited."
"Don't say such embarrassing things...♡"
"You're so embarrassingly overwhelmed. Besides, you and I are close."
"Yeah, but...♡"
"--I'm going to take it off."
"Aah♡"
--What do you mean, take you off?
As if to answer Jin's question, there was a rustling sound of clothes rustling.
A little later, a pair of black panties, the same color as her bra, were thrown out of the scarlet hakama. They fell to the floor with a sticky, squishy sound.
"Aauuuuuuuhh♡"
Jin was staring at the love juice-stained underwear, and was shocked to see Yui shaking her hair.
"Aaaaaahh♡ Hyaaaaaan♡ Right there, right there♡ That's the sensitive spot♡"
It was impossible to see what Koichi was doing inside the hakama. But it wasn't hard to imagine it, seeing Yui's face as she raised her chin and let out a squeal.
"No, not on my clitoris♡ No licking, no♡ Rubbing your beard against it, Aaahhn♡ Aaaaaaahh♡ It feels good♡ I'm sensitive to that♡"
Yui's shameless commentary. There was no need to, but Jin listened more intently than ever. He couldn't help it. His whole body trembled with emotions he had never known.
"Kissing♡ Aah, Aah, Aah♡ Your tongue is in♡ It's coming inside my vagina♡"
Koichi's cunnilingus takes Yui to heaven in an instant. Her semen-covered face is distorted with pleasure, and saliva is spilling from the corners of her mouth.
"No, no, no, no, I'm cumming, I'm cumming, my subordinate is making me cum♡ Aaaahhh♡ Aaaaaaaaa~~~♡ Cummmiiiiingg♡"
Her whole body is convulsing, and there's no doubt that she's reached climax, not just by his words, but by his looks. It's the first time he's seen his lover's orgasmic face. He's immersed in the pleasure of orgasm.
"Haa-♡ Haa-♡ Haa-♡ Haa-♡ I can't do this...♡"
Yui was whining and shaking her shoulders. No matter how difficult the situation, no matter how disadvantaged she was, it was unlike her to never give up.
Koichi crawled out of her hakama. He looked down at Yui, who was basking in the afterglow of her orgasm, without changing his expression. Their relationship was not that of subordinate and captain, but that of ruler and servant.
Koichi's penis, which had already ejaculated once, was still rock hard, and Yui gazed at it with a dazed expression. After a short while,
"Auuh."
Suddenly, Koichi pulled Yui's arm and forced her to stand. Urged by this, she put her hands on the locker and thrust her butt out towards Koichi. Just like a whore seducing a man.
Violated.
His precious lover's virginity, his first time, was taken by another man.
This time, now, it was time to make a move. He couldn't tolerate this any longer.
Jin had made up his mind, but--
"Are you… not going to put it in... ?"
Turning his head, Yui asked Koichi innocently.
--Wait.
Jin's throat was bone dry. Yui's tone of voice sounded as if they'd made love many times before.
--Perhaps already. Already. A long time ago.
Jin should have noticed sooner how the two of them had gotten used to each other, but perhaps his mind refused to understand.
Koichi remained silent in response to Yui's question.
After a long silence,
"Do I have to tell you?"
Yui asked again, quietly. Koichi answered with a nod. Yui, who had accepted this, lowered her eyes, bit her lip, and hesitated for a moment.
But the next moment, she was smiling and speaking in a sweet voice.
"Give me your cheating cock♡"
And what's more, she said something outrageous. Yui used vulgar language that she would never utter.
"Give me Koichi's cheating cock♡ in Yui's pussy♡ Give me your cheating cock♡ Stick it in♡ Poke it in♡ Poke it in a lot♡ Splash your cheating cock's cheating sperm♡ into my pussy♡"
The shock that hit Jin was unlike anything he had ever experienced before. He collapsed on the spot.
Koichi seemed satisfied with Yui's fawning behavior, as he laughed lewdly.
"You're a perverted captain, exposing your juicy pussy. You wanted it all the time during work today, didn't you? You're not fit to be a captain if you want your subordinate's cock. And it's not Jin's, it's mine."
If Jin knew the Yui, he would be furious at this. But Yui accepts it. He accepts it happily.
"That's right♡ Jin-kun won't do♡ It has to be a cheating cock♡ I can't take it anymore♡ I've held back this long, so please, Koichi♡ Please, please♡ Do it♡ Please♡ Cheating cock♡ Stick it in♡"
"You're a hopeless captain, Yui"
"Aa--♡"
He grabbed his big butt with a thud.
In a standing doggy style position, he stuck his sticky semen-covered erection in. He wasn't wearing a condom.
Slosh, slosh, slosh, without resistance or snags, Yui's vagina swallowed Koichi's penis. It was like a hole just for Koichi.
"Aaaaaaaaahhhh~~~♡"
Screams of joy echoed through the locker room. She was no longer a virgin. Her vagina was used to accepting men. Jin was finally able to accept that fact.
In the end, Jin couldn't interrupt. All he could do was stare at his fiancée and his comrade having sex.
"Auuh♡ Auuhh♡ Deep♡ So deep♡ All the way to the back♡ It's coming all the way to the back♡ Aaahn♡ Aaah♡ Aauuh♡"
The uninhibited piston movements began, and the only sounds Jin could hear were the dry thumping sounds and Yui's moans.
"Kuaaa♡ Kaaaaaah♡ Koichi, Koichi♡ I love you, I love you, I love you, I love you, I love you♡"
Another shock hit Jin. Not only was Yui a source of pleasure, but he began to whisper words of love to Koichi himself.
"Koichii♡ Koichii♡ I love Koichi♡ I love having sex with Koichi♡"
"You've become quite the erotic shrine maiden, Yui. Aren't you ashamed to be an exorcist shrine maiden?"
"I'm embarrassed♡ But♡ It feels so good♡ Sex with Koichi♡ It feels too good♡"
"You're such a pervert shrine maiden, getting so worked up from cheating sex. The fans of Kagaribi of Demon Slayer will be disappointed when they see this. And so will your subordinates."
"I can't help it♡ Because I♡ I'm a pervert shrine maiden♡ I'm not fit to be an exorcist♡ I'm an erotic shrine maiden♡ I don't care about demons♡ I don't care about cursers♡ It's only Koichi's cock♡ All I can think about is cheating cock♡"
Yui can't stop now. She spat out words that degraded her one after another. She moved her hips in time with Koichi's thrusts.
"And cheating in the office? Your subordinates and Jin will be sad."
"Oh, no♡ Koichi forced me♡"
"Did you say something?"
"Fuuaaaaaaaahn♡"
Her voice of protest was silenced by a deep thrust into her vagina. Yui still looked happy. If she hadn't desperately put her hands on the locker, she would have collapsed on the spot.
"You're not just a disqualified exorcist, are you? Commander. You have a fiance, but you're having sex with another man."
"That's right♡ That's right♡ I'm sorry Jin♡ I'm sorry♡ I'm♡ I'm a disqualified fiance♡ I love cheating♡ I'm a naughty shrine maiden♡"
Although she apologized, Yui didn't seem sorry. Rather, it seemed like she was enjoying the sexual intercourse, taking advantage of Jin's presence.
"Aah ♡ Aah♡ Aahn♡ Koichi's ♡ Koichi's cheating cock ♡ It's getting bigger again ♡ Amazing ♡ Amazing ♡"
"Yui's grip is good too"
"Yes ♡ I'll do my best ♡ I'll do my best so Koichi will be happy ♡"
There were signs.
Koichi increased the speed of his hip thrusts, and Yui arched her back like a bow. Her pathetic moans deepened.
--Hey, no way.
"Ah♡ Aauh♡ Auuh♡ Aauh♡ Aaaー♡ Aaaaahー♡ Aaaaaahhnー♡ Aaaaaaaaah～～♡"
"Kuuh"
A faint moan escaped Koichi's mouth, and his hips, which had been moving smoothly up until then, stopped. He was thrusting all the way to the back.
"It's coming♡ It's coming♡ It's coming～～～～♡"
Yui roared.
"Koichi's sperm♡ Semen♡ Thick semen♡ It's being spurted into my vagina♡"
Jin was overcome by a despair that he had never felt even in that nightmare.
He was ejaculating raw. Making a baby is something that only lovers, married couples, are allowed to do.
He was far ahead of the others. Leaving aside her lover Jin, Yui had already done almost everything with him.
Jealousy alone was not enough to settle this. But he didn't have the energy to take it out on Koichi. He was simply overwhelmed by the overwhelming feeling of defeat.
"Hiiyaaaann♡"
His penis was pulled out rudely. The thick semen dripped to the floor. Even after two ejaculations, and even after he had spat out a huge amount of sperm, Koichi's cock was still going strong. With Jin, it went limp in one go. Something that thick was impossible.
Losing the support of his penis, Yui's hands slipped on the locker, and this time she was about to collapse.
Koichi held her gently in his arms.
"Haa...♡ Haa...♡ Haa...♡"
Held in strong arms, Yui looked at Koichi with glazed eyes, breathing sweetly intermittently. Koichi responded to her gaze, and the man and woman gazed at each other.
They looked exactly like lovers, or engaged couple.
"Yui"
"Koichi--"
Without either of them saying anything, they leaned their faces closer to each other.
Unlike the intense sex they had had earlier, this was a gentle kiss, as if they were caring for each other. Their tongues were sloshing, and they caressed each other's genitals. It felt like they still hadn't had enough. He had a feeling that round two was about to begin.
It was no good going any further.
Jin fled the scene as if fleeing. All he could do was sulk, and he couldn't intervene in anger.
He didn't even remember how he got home.
He lay in bed in the clothes he was wearing.
--Please, this time too, it was a dream.
Even though he wished for that, the image burned into his retina wouldn't go away. Even if he forced his eyes closed, he couldn't sleep. He slapped his cheek with all his might, but there was no way this pain was a dream.
Suddenly, his smartphone vibrated.
Hopefully it was Yui, he picked it up, but
"What is this...?"
It was an email sent from an unknown address. A strange URL was attached to the body of the email. Jin wondered if he should just ignore it and contact Yui himself, but he wondered what he should say to her, and so on and so forth――
"......"
He tapped the URL as if drawn to it.
It connected to a video file.
He would come to deeply regret that action.
