Foreword: This erotica, like all on my account, was originally an ERP session that I took and re-wrote as a novel. This one was translated into english as well. I try my best but english is not my first language, and styles inconsistency can happen since it's was originally written by 2 people. The original idea was mine, and I played the Coach while the other person played the couple. It is my first work in this way, and I am open to constructive criticism.

The sky is overcast at the beginning of this evening. In the dojo of this medium-sized city, the cheers, shouts of joy and cries of frustration caused by the regional Taekwondo team tournament have given way to silence tinged with the sound of raindrops hitting the windows. The atmosphere would be cozy if it weren't for the slight smell of sweat. Marion is waiting for her husband Julio, sitting in the bleachers. It seems as though everyone has left, which is possible since Julio's coach owns the keys to the dojo.

For Julio, however, the atmosphere is far from peaceful. With his feet against the wall, he leans with all his weight against the door of one of the cabins used by athletes to change clothes. He knows that the small stainless steel latch on this cabin wouldn't be enough to contain the rage of his coach.

His coach, on the other side of the door, is furious; despite a year of intense training and private lessons, Julio has been unable to score a single point and cost his team qualification. Not that he needed it to lose his cool: if people call him Oni, it's not just because of the Japanese demon tattoo covering most of his skin but also because his aggressive temperament is on par with said demon.

Oni, 190cm tall, shaved head, bushy but well-groomed mustache, black "wife beater" shirt highlighting his competitor's musculature, Adidas sweatpants and sneakers, beats on this door as if it owed him money.

"You're going to come out of there, little bastard! ONE YEAR taking care of you more than others, and that's how you thank me?! When you your wallet and phone robbed in front of your wife and came crying into my dojo for me to teach you self-defense, I should have sent you to hell! " he shouts while throwing hands and feet against the door.

Marion is tired of waiting. It's already late and her husband has lost; she wants to be there to comfort him. She decides to approach the locker rooms to see if everything is OK, but she is surprised to hear the coach's shouts. She hurries to go see what's happening.

"What on earth is going on here! Where is Julio?!" she asks.

Marion spoke in a confident tone that will quickly change upon seeing the coach's anger.

Julio recognizes his wife's pace and releases his force on the door. Enraged, Oni turns barely towards Marion and barks simply: "Shut up, you fool!"

Taking advantage of Julio's moment of inattention, Oni slips his arm into the opening of the door and seizes him by the neck.

"I've got you, little bastard!" he growls through his teeth like a snake, tightening his grip on Julio's throat. The door still separates the two men, but Oni's arm is long enough to start pressing Julio against the wall of the small cabin.

Julio grabs his coach's hands and tries to free himself. Breathing heavily, he attempts to break away from the grip around his neck.

Marion, shocked by the scene, quickly approaches to try to separate the two men: "Hey! Calm down, both of you! It's not worth it!"

Catching a glimpse of Marion moving towards him out of the corner of his eye, Oni's fighter instinct pushes him to turn away from Julio and release his grip as he turns toward Marion: "What do you want, you? You don't understand anything. This dojo is my life; every year I qualify my team for Nationals..."

He stops there when the sight of Marion's femininity snaps him out of his testosterone-fueled mindset tournament put him into.

"Okay... Maybe I don't need to hit him. But you know, Marion, he will have to pay for this loss. The whole team is angry, not just me. They won't soon forget how he ruined everything." Julio catches his breath and feels reassured seeing his coach finally calm down. He touches his neck that still hurts him.

"I'm sorry Oni... My opponent got the better of me... I... I..." He stammers.

Marion approaches gently and says, "I understand the importance of your dojo Mr. Oni... And we are both sorry for Julio's loss... But we will make amends, I promise you. How? I don't know yet, but you have our word."

She then comes close to her husband, still leaning against the wall from his fight and strangulation.

Oni now stares at Marion, ignoring Julio completely: "Do you know what it feels like to be the one carrying the responsibility for a loss like that? The whole team hates him; they're already talking about replacing him next season. Maybe he should even give up Taekwondo after such humiliation. What do you think, Marion?" He says with a sly smile, leaning forward slightly with his fists on his hips, as if lowering himself to their level.

"Well... Julio has made enormous progress, hasn't he? Of course, he isn't at the same level as the others, far from it... But he put in a lot of effort for the team. Please... It does him good to come here... I'm sure he will do better next year." Marion looks at the coach and speaks in a soft voice.

"I'm sure we can find a way to keep me on the team. Please, coach..." Julio replies, still a bit out of breath

Oni realizes more and more that he can gain something from this initially frustrating situation. "Of course I understand. But what I mainly understand is that I can easily make his life even more miserable. Imagine if I spread the rumor that he deliberately gave up on purpose, out of cowardice or worse, to sabotage the team. I could convince the others to exclude him definitively..." He says as he gets closer and closer to the couple, invading their personal space more and more, cornering them in the small cabin.

"Mr Oni... You know that's not true, why would you do that? We have always thanked you for what you taught me ...." Julio responds uncertainly, a bit afraid of being trapped again in the cabin.

"Julio is right! We should be able to find an arrangement, Mr Oni? I'm sure we can, yes." Marion has even more fear as she looks at the mountain of muscle blocking their only exit way.

Oni takes one last step forward, leaving enough space for the door to close behind him, its sound echoing ominously in the empty locker room. There is now no more space between him and them.

"Yes, we can surely work something out." he says as a diabolical smile begins to form on his face

In an instant, the expression on his face changes completely. His face becomes impassive except for his eyes which become authoritative. At the same time, his gaze turns towards Julio.

"Sit down." he says in a cold and authoritative tone.

A bit surprised by the order, Julio complies within only a few seconds, sitting on the bench. The couple looks at each other, both worried about this situation.

"Good boy." simply says Oni before turning to Marion.

With a calm but firm movement, he grabs Marion's throat and moves close to her ear so that only she can hear:

"Look at him... Just at the right height."

In his Adidas tracksuit, the outline of an erection begins to grow and presses warmly against Marion's hip, just a few centimeters from Julio's face.

Marion is too scared to react. She becomes a mere spectator of the scene. She tries her best to keep her breathing and calmness in this strange situation.

Julio straightens up "Hey! Let go of her, coach... She has nothing to do with it!" His voice trembles, as he's also afraid of this situation.

Oni's knee collides brutally with Julio's lower abdomen to make him sit down again.

"You'll speak when I give you the order, dirty dog..." he says before turning towards Marion "Both of you better obey me... Unless you want a little visit from us at your place with the whole dojo team. I'm sure they would love to give you a chance to make amends."

Julio sits back down immediately under the impact of the knee. His body is bent in two and his breath cut off as he holds his stomach.

Marion gasps seeing the strength of the blow.

"STOP! We will obey you! But please don't hurt anyone... I beg you..."

"You and your useless piece of shit, you better do what I tell you!" says Oni as he fixes his authoritative gaze on Marion.

While his right hand still firmly holds Marion's throat, his left hand seizes her right hand and places it on the erection that now almost reaches his knee.

Oni grins slyly. "You can see I'm quite uncomfortable in here..." he says as his penis seems to want to push Marion's hand away through his sweatpants.

"You will give your little dog the chance to be forgiven. Unless you want us to come and "forgive" you with the rest of the team at your home?" he says sarcastically.

Marion is still paralyzed with fear. Unable to resist, she lets herself have her hand taken and stroke his erection.

"No... Don't do that... We will obey you... I promise."

Julio isn't much braver. Watching the scene unfold, his stomach is still painful for reacting against the coach who is now using his girlfriend.

"We will obey you, I swear!" Julio adds.

Oni looks back and forth between Marion and Julio.

"Nice promises... We'll see if you can keep them."

Oni releases Marion's throat to grab her hair at the back of her head and bring her closer so he can whisper in her ear:

"Pull my dick out, and let him suck on it..." He says slowly in a threatening tone.

The couple is still in shock and it will take them a few moments to realize what the coach really wants. Paralyzed with fear, Julio gestures for Marion to obey the coach. So she goes to put her hands in his pants to pull out his dick. She is torn between disgust and surprise due to the size and weight of the erect penis as Julio stares at it with terror.

Excited by this unusual situation, Oni's penis grows hot and moist with sweat, hardening even more in Marion's hand as it points towards Julio's face.

Looking down at Julio, he says to Marion:

"Check out his head, it looks smaller than my dick!" he chuckles, making his penis bob before Julio's face.

From his hand that held the young woman's hair, he forces her to look him in the eye.

"You know what you have to do..."

The couple exchanges a look and understands. They will need all their strength to survive this ordeal. Julio, still terrified and blushing with shame, comes to take Marion's hand on the coach's penis and masturbate him very gently. He doesn't even know where to start, but he finds the courage to lick the tip a few times.

Oni suddenly slaps Julio's hand hard.

"Did I tell you to touch me, little shit?!" he says as his voice trembles with anger in the locker room.

He turns back to Marion again, pressing his forehead against hers to intimidate her.

"It's you who has to make him suck, dumbass! You're starting to make me lose patience..." he threatens in a menacing tone.

With his left hand, he grabs Marion's vulva through her pants.

"If you don't want to be useful, maybe I should just do it myself..." he says before turning back to Julio; "Is that what you want?!"

Marion screams, a mix of surprise, pain and perhaps a little pleasure as she gets grabbed. She hastily takes the coach's dick in her hand to direct it towards Julio. "Sorry! Coach! Please!" she moans.

Julio begins to envelop the penis with his mouth, hoping he can calm him down. He had never done this before so he sucks gently.

Seeing the couple's reaction, Oni calms down.

"There you go, see it was not that difficult..." he tells her before turning back to Julio.

"And you... Still good for nothing, look at that, I give you another chance and you don't even take it properly!"

In a quick move, Oni pushes his hips towards Julio, pressing the back of his head against the wall behind him and forcing his mouth to open wide enough to let his hard cock enter fully.

"Mmmh, this is better, what do you think about that my dear?" he says mockingly as he turns back to Marion while rubbing now through her pants.

Julio finds himself forced to have both the penis in his mouth and to suck it. It disgusts him a little but he dare not complain or disobey.

Meanwhile, Marion clings lightly to the coach's penis, not only to guide it towards Julio, but also to hold onto something. Her intimacy is sensitive and the coach isn't very gentle. Biting her lips to keep from whimpering, she tries to make sense of what is happening around her.

Seeing Marion clinging to his erect penis, Oni grabs her hand in order to force her to jerk him off in Julio's mouth.

"Come on, give it a little effort my dear, you won't let your boyfriend do all the work, right?" he says mockingly.

"That's not true... I... I really don't like it at all," she replied, blushing even more intensely. Yes, she is wet, but admitting that is out of the question. She gently masturbated the coach who prevented Julio from pulling away. The couple had never felt so degraded before.

"Ah, is that so?"

Still fucking Julio's mouth, the coach lowers Marion's pants and underwear to expose her pussy.

"Look at this, Julio!"

With one hand, Oni grabs Julio's head to force him to look at Marion's vulva. With his other hand, he plays with it for a few seconds, slides a finger into her vagina, then removes his hand so that Julio can see the wetness on his fingers.

"Look how much your wife loves this, watching you getting fucked by a real man!" says Oni as the excitement of the situation had made his dick rock hard in Julio's mouth.

"Don't listen to him!", Marion tries to contradict him between two whimpers. She fights hard to hold back tears while looking at her husband, but it is becoming increasingly difficult. Both her and Julio have a tear in their eye as they focus on breathing. He feels a form of pleasure go through his body.

"Yes, she's right, Julio, don't listen to me..."

Oni removes his erect penis from Julio's mouth and slides his fingers covered in pussy juices back into it.

"Taste it instead! Haha!"

After that sadistic laugh, Oni starts thrusting his fingers in and out of Julio's mouth with his fingers, making sure to spread Marion's vaginal fluids all over his mouth.

With his other hand, Oni grabs his erect penis and slides it between Marion's thighs, moving back and forth against her vulva, ensuring that Julio has the perfect view of the scene.

"Between Julio's saliva and Marion's dampness, you make it so easy... It could almost slide in on its own!" he says jubilantly.

As for Julio, his coach's fingers full of his wife's pussy juices bothered him less than the cock from before, even if it reminds him that he is letting his wife be touched. But this is just the beginning. Seeing his coach's cock approach the intimacy of his wife gives him a pang in his heart. Meanwhile, she is terrified at the idea of receiving that inside her, especially in front of her husband.

Seeing that Julio seemed to "relax" around his fingers, Oni decides to speed things up.

"Do you like the sight of a real cock on your wife's pussy?" he asks contemptuously to Julio. "Wait, we're going to do even better!" he says as he turns towards Marion.

Oni removes his fingers from Julio's mouth and, in one motion, pulls Marion's pants and underwear down. In another gesture, he takes off one of her shoes to completely free her pant leg, grabs the now naked leg of Marion, and places her foot on the bench next to Julio.

Julio now has a clear view of his wife's intimacy, her vulva at eye level.

Oni takes hold of Julio's hand and places it around his hot and lubricated cock, and begins guiding it towards Marion's pussy.

"Come on, little shit, you know the only thing left for you to do, show me how much you want to be forgiven..." he says threateningly to Julio.

"Coach... You don't really want me... To... I mean... Please coach... I just lost a match... Marion is innocent..."

Julio has a bit too clear of a view on the wet lips and penis of the two other people. As for Marion, she bits her lip at the idea of betraying her husband in this way. A part of her is disturbed, scared but also... Excited. She closed her eyes.

Oni grabs Julio by his hair, forcing his head back. With his other hand, he gripped Marion's throat to keep her pressed against the wall.

"It's too late for feelings, little son of a bitch! You had my dick in your mouth just thirty seconds ago... If you back out now, I'll tell the team what you were willing to do to be forgiven, and don't think they'll be soft on a guy like you..."

Oni moves closer to Julio, speaking to him in a calmer but also more sinister tone.

"From now on, it's not about what you want anymore, what counts is what I want."

"Yes sir..."

Another humiliating confession of defeat. The couple is desperate before this man. Julio eventually yields to the coach's demand and guide his dick towards the entrance of Marion who is still tensing.

"There we go, that's better." said Oni with a satisfied smile.

Increasingly excited by the situation, the Coach speeds up a bit more, pushing with his hips in the direction led by Julio. Oni feels the heat and moisture enveloping his dick: he continues to push further, slowly but steady. At first, there is almost no resistance; Marion seemed to have been eagerly waiting for this moment. But when it's time to pass the crown of the dick, a problem "in size" arises. Marion had clearly not been accustomed to being taken by something so thick, but this feeling of resistance only aroused the coach even more. Continuing his thrusting, the coach's dick stretches the vaginal walls of Marion indefatigably, filling her completely.

Marion feels her lips spreading too much and the coach penetrates her painfully. She bites her lip and whimpers softly. Julio turns away a little

"Stop... It's too big... It hurts... Please!" exclaims Marion.

The pleasure caused by Marion's pussy is already fogging up the Coach's mind. With his head back, eyes closed, he feels that he is now completely filling her, but it isn't even halfway down the length of his thick dick, and he has no intention of stopping there.

As if an echo from the depths of the mist, Oni suddenly becomes aware of Marion's complaints, and comes back to himself. He gives Julio a chilling look and says:

"I think your wife needs your help... or are you going to stay here doing nothing, like you were when you both got robbed?"

Oni grabs the back of Julio's neck and pushes his head against the spot where his thick dick is mixing with Marion's wet pussy.

"That's where it happens... Lick, dog." he orders him.
