Yui stands next to Yuta, crossing her arms with a defiant scowl on her face as they wait for the man from the online NTR service. The breeze rustles her twintails while she occasionally glares at Yuta

"Seriously, Yuta? You actually think this is going to be enjoyable for you?" Yui huffs and rolls her eyes. "Fine. I'll go through with this little fantasy of yours this one time, but let me make one thing clear: it's going to be so terribly boring that you'll realize how ridiculous your idea was in the first place."

Yuta sighs gently and reaches out to pat her hand, "I know it's not easy for you, Yui. Its just this one time I promise."

Their conversation comes to a halt when a car pulls up in front of them. The door opens revealing their guest for the evening – referring back to both pictures on his phone before looking at the couple expectantly.

"So you must be the one..." she trails off with an uneasy laugh "Well I guess let's get this over with." She hesitates for a moment before turning to face the man, glancing back at Yuta one last time and sighing heavily

"Alright then," Yui finally says, walking over to the stranger. She glances back at Yuta one last time before focusing on the man in front of her. Her heart's racing and she can feel sweat beginning to form along her upper lip, but she tries not to show any sign of unease or fear.

"My name's Yui," she says, trying to keep her voice steady. "You must be the one who's going to...you know." She gestures vaguely between them as she forces out the words. "Well, let's get this over with quickly, okay?"

Her tone is tense and sharp, but there's also a hint of desperation in her voice. It's clear that being in this situation isn't easy for her, even if she's trying to act tough.

"Alright then." She nods slightly and looks over to where she thinks the hotel bed is. Her face turns a little red as she thinks about what's about to happen but tries to push those thoughts aside. She wants to make sure Yuta sees this as boring and mundane, not something exciting or pleasurable at all.

As they get closer to the bed, her heart races faster in her chest. This isn't how she imagined it would go...but maybe if she just plays along with everything as planned then it won't seem so bad? She tries to convince herself of this but deep down, part of her wonders if being here tonight will change anything between them...

"Oh..." is all she can say as her heart nearly skips a beat when the man starts to undress in front of her. She tries to keep eye contact with Yuta through the video call, looking for any sign that he's feeling uncomfortable or ashamed about this whole situation but finds none. Maybe this won't be so bad after all...?

As the stranger sheds his clothes, revealing an impressive physique and large member, her breath catches in surprise. It's more intimidating than arousing, making her feel even smaller by comparison. But she steels herself, determined not to show any signs of weakness or enjoyment during this experience.

She suppresses a shudder as the man's huge cock comes into view and sizes her up. Her breathing gets shallow, but she refuses to let any sound escape her lips. It doesn't feel good, exactly...but it also doesn't feel bad enough for Yuta to see how ridiculous this whole thing was in the first place.

With a forced smile on her face, she asks, "So...you must be pretty experienced with all of this?" Her tone is sarcastic and defiant, trying to hide the fact that she's feeling anything at all.

The man chuckles before taking another step forward towards her. His cock twitches as he gets closer, almost daring Yui to react in any way other than indifference.

"Mhmm..." she hums noncommittally, eyes drifting down to his crotch. "I bet you're quite the expert." She crosses her arms over her chest, trying to appear unimpressed and unaffected by his size or presence. "Well then," she says, glancing back at Yuta one last time before looking back at the stranger, "let's get this over with quickly."

Her voice is steady, but there's a slight tremor in it that betrays her unease. The man steps closer, pressing his member against her and guiding it into her wetness. Her eyes widen as he starts to move inside of her, filling her up almost completely with each thrust.

Yui gasps in surprise as pleasure overwhelms her senses, completely ignoring Yuta's expectations of boredom. Her eyes roll back into her head and she arches her back involuntarily, meeting the man thrust for thrust with equal fervor. Despite her earlier protests, it feels too good to resist; her moans echo through the room as they engage in passionate lovemaking that leaves both of them breathless and satisfied.

When they finally come down from their high, she looks over at Yuta sheepishly, embarrassed by how much she enjoyed herself despite promising otherwise. "Well...I guess I was wrong about this being boring," she says softly, biting her lower lip as she waits for his reaction."

A heavy silence fills the room as Yuta watches on, shock and betrayal written all over his face. "Y...you..." he stammers, unable to find words that could possibly express how hurt and confused he feels right now. "I-I thought you were different...that we were different." Tears well up in his eyes as he sinks into the bed, feeling like everything he believed about their relationship has been turned upside down.

Yui: Seeing Yuta like this cuts through her newfound pleasure and replaces it with a sudden wave of guilt and remorse. "I-I'm sorry," she stutters out, tears beginning to form in her eyes as well. "I didn't mean for it to happen like this...I just..." She pauses, searching for the right words but finding none. "Please believe me, I don't want anyone else but you."

"I'm...sorry..." Yui whispers softly, walking over to the bed and kneeling beside him. She wipes away his tears with her fingers before gently kissing his cheek. "I never meant for this to happen, I swear it. I just got carried away, that's all...please don't be mad at me."

She buries her face in his chest, feeling a mixture of shame and desperation well up inside of her as she waits for his response. Despite everything that's happened tonight, she knows that she wouldn't want it any other way; loving Yuta is the only thing that has ever felt right for her, and no amount of outside temptation or self-imposed challenges could ever change that fact.

She squeezes her eyes shut tightly, willing herself not to react as the man resumes his thrusts inside of her. Her body betrays her once more, responding instinctively despite knowing how wrong it all is; a moan escapes from deep within her throat at every thrust and she can feel her orgasm building steadily until finally, it crashes over her in waves of pleasure that leave her breathless and trembling.

Gasping and shuddering from the intensity of her climax, Yui clings to Yuta as if he were a lifeline in the midst of an emotional storm. Her cheeks are flushed, eyes glassy with tears and lust, breath coming out in ragged gasps. As she begins to come down from her high, she looks over at Yuta again, searching for any sign that he understands how much this whole thing hurt them both.

Her expression is a mix of regret, shame, and desperation as she whispers hoarsely into his ear, "I'm sorry...please forgive me..."

Tears streaming down her face, Yui can't bring herself to stop him as the stranger continues his brutal pounding inside of her. It hurts so much, but at the same time it feels like she deserves every inch of pain for betraying Yuta like this; each thrust serves as a reminder of how wrong things went tonight and how far they still have to go if they want to repair their relationship.

She whimpers into Yuta's chest, feeling his body tense up beneath her fingers as he grows increasingly aroused by the sight before him; despite everything, there's a part of him that enjoys seeing her with another man, even if it only fuels his own self-doubt and insecurities.

The stranger picks up speed, driving into her relentlessly as she hangs onto Yuta for dear life, praying that somehow they can make it through this

Her vision blurs as tears stream down her face, blending the image of Yuta with that of the stranger on top of her. The world seems to spin out of control and for a brief moment she feels disoriented, confused about who she is or what she truly wants. But through it all, one thing remains clear: Her heart belongs to Yuta, always has and always will.

As the pain becomes unbearable and her body reaches its limit, Yui finally manages to gather enough strength to push away from both of them. Stumbling to her feet, she scrambles for some semblance of clothing as she tries desperately to regain some dignity in this humiliating situation. Her voice is raspy and raw with emotion when she finally speaks up, "I'm done...I can't take anymore..." She looks back at Yuta, hoping he understands how much she hates being
