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.

"Hmph!" Glaring at the man in front of her, she thinks to herself that he looks even better than what she expected from his pictures "Well, you're not as bad-looking as I thought. Yuta didn't lie when he said you were experienced...so I guess it won't be a total waste of time." She winks at her boyfriend playfully, still holding onto her defiant expression while trying to hide the nervousness in her voice

"Oh?" Her curiosity piqued, she tilts her head slightly and crosses her arms underneath her breasts "Well, since it's Yuta's fantasy..." She glances over at him, trying to gauge his reaction "...I guess we could start with you just touching me...if that's okay with you?"

Yui steps closer to the man, allowing him a better view of her body. Her heart races in anticipation as she awaits his response.

Surprised by the man's bluntness and his advice, she hesitates for a moment before responding. She glances back at Yuta, trying to read his expression, but he seems unfazed. Deciding to play along, she gives a small shrug "Okay..." She turns her attention back to the man "...Bowling it is."

With a sigh of resignation, Yui follows the stranger into his car. As they drive towards the bowling alley, she attempts to make conversation with him in between glances at Yuta on her phone screen.

"Oh, uh...I dunno...skateboarding, I guess." She glances away, feeling a bit awkward and exposed with his hand on her thigh. "It's just something I grew up doing. Yuta doesn't really like it though..." Her cheeks flush as she trails off, realizing she might have said too much.

She glances downward at the man's crotch and feels her cheeks heat up again, taking in the sight of his impressive erection pressing against his pants. Swallowing hard, she tries to maintain eye contact while casually moving her hand down to subtly touch it through his slacks. The feel of him growing even harder beneath her fingers excites her, and she finds herself wanting more than just teasing Yuta tonight.

The bowling alley comes into view, and the man pulls into a parking spot nearby. "Alright," she says as she climbs out of the car, trying to regain some semblance of composure, "let's go have some fun." With each step towards the entrance, her body sways enticingly in an attempt to draw attention away from Yuta and onto herself.

She feels her cheeks heat up as he gropes her ass, grinning mischievously despite herself. "One round should be enough," she replies with a suggestive wink, already imagining the kind of flirting they could engage in while playing together. As they approach the lanes, Yui makes sure to keep close contact with him, enjoying the feeling of his body against hers and reveling in the power she seems to have over both Yuta and this stranger for the evening.

Glancing at Yuta out of the corner of her eye, she hesitates for a moment before obeying, straddling the man's lap as instructed. As his tongue finds its way into her mouth, she moans softly and wraps her arms around his neck, deepening their kiss. Her heart races with excitement and desire, making it difficult for her to focus on anything else.

"So," she says breathlessly between kisses, "do you want to see me bowl...or do you have something else in mind?" A mischievous grin spreads across her face as she lets the possibility hang in the air.

Nodding obediently, Yui focuses on the game in front of her, occasionally glancing back at Yuta to gauge his reaction as she plays. Each time their eyes meet, she feels a thrill run through her body. Despite trying to maintain a level of disinterest towards her current "partner," it's becoming harder and harder for her not to respond to the physical attention he's giving her.

As they continue bowling, Yui starts to experiment with teasing him more overtly; she begins wearing his suggestions on her clothes a little looser or tighter than before, revealing hints of skin that weren't there before. She even slips lower into the man's lap whenever Yuta isn't looking, grinding against him suggestively as they play together.

Her body aches with need, and she can tell he's struggling to contain himself as well. It's

Nodding in agreement, Yui follows the man to his car once more. This time, she can barely contain her excitement as they drive off towards the cinema. The anticipation of what might happen between them tonight fills her every thought, making it difficult for her to focus on anything else. As they find seats in the darkened theater and settle in, Yui leans closer to him, feeling the heat from his body radiate against hers.

With a mischievous glint in her eye, she begins exploring his touches further; she sits close enough that their thighs are pressed together, allowing her to feel every movement of his hand as it caresses up and down her leg. Her breath comes faster with each teasing brush against sensitive skin, making her all too aware of how aroused she's become in such a public place.

Glancing over at Yuta one last time before looking back

Her heart races as the stranger whispers in her ear, his words sending shivers down her spine. With a mixture of excitement and defiance, she reaches out to tentatively grasp him through his pants. The feeling of his hard length beneath her fingers ignites a fire within her, making it impossible for her not to respond.

Careful not to draw too much attention in the darkened theater, she begins sliding her hand up and down his length in time with each heartbeat. Each stroke sends waves of pleasure coursing through her body, threatening to undo her completely. Her eyes drift back over to Yuta one final time before locking onto his own; unspoken words pass between them as she silently dares him not to react too strongly at the sight of their intertwined hands.

With every passing second, the thrill of their secret game becomes more intoxicating. As she focuses on pleasuring him, her body betrays her; a thin sheen of sweat breaks out across her brow and upper lip, and her breathing grows shallow and rapid. Her movements become more desperate as she tries to balance the pleasure they share with maintaining the illusion for Yuta's sake.

Without warning, he hands find their way beneath her skirt, sliding up her thigh to tease her through her panties. The sensation is so intimate and intense that she moans loudly despite herself; for a moment, all three pairs of eyes meet in a charged exchange before returning to their respective films. But it's clear now: this game has gone far beyond anything anyone expected or prepared for tonight.

"Okay," she whispers back, glancing over at Yuta before quickly following the man to the bathroom. Her heart races with anticipation and a strange mix of fear and excitement as they step inside one of the stalls together. She listens for any signs of Yuta getting restless or suspicious but hears nothing except the sound of the movie playing through his phone.

When the stranger motions for her to join him on the filthy toilet, she hesitates only momentarily before complying. The closeness and intimacy of their position is nearly overwhelming; every breath they share seems charged with electricity as their bodies brush against each other. His hands roam freely up and down her body now, teasing and pleasuring her in ways she never imagined possible.

"So," he whispers into her ear, his hot breath sending shivers down her spine, "what do you

Without thinking, she moans out loud at the feeling of his hand on her bare skin. The thrill of being touched so intimately in such a public place makes it impossible for her to resist; her body arches into him, seeking more contact as he teases her mercilessly. Her heart races and her breath comes fast as she anticipates what might come next. "I-I don't know..." she whispers back, voice trembling with desire. "Just...just do whatever you want to me." Despite her protests, a part of her relishes in the thought of surrendering control completely. She leans into his touches, eager for him to take what he wants from her body and soul.

With a mix of hesitation and desire, she complies, slowly lowering herself onto the man's lap on the toilet seat. Their movements are awkward but urgent, grinding together as he presses into her with every thrust. She winces in pain when he bottoms out against her cervix, but doesn't stop; instead, she leans forward and crashes their lips together, lost in the moment.

Her body quivers with the force of her orgasm, sending waves of pleasure coursing through both of them. Her breath comes ragged as they continue to fuck, oblivious to the world around them. The bathroom door creaks open slightly, but neither of them notice until it's too late: Yuta stands there, wide-eyed and shocked at the scene before him.

"I-I'm sorry..." she stammers, trying to process what just happened as they

"No...I..." Her face burns red as she struggles to form words through her shame and disbelief. "I'm sorry," she manages finally, tears beginning to well up in the corners of her eyes. "I-I didn't mean for this to happen." She looks back and forth between Yuta and their stranger, feeling like a fool for letting things get so out of control.

I-I just...I wanted to make you happy...make it up to you somehow..." She trails off, unable to meet either of their eyes as she struggles with the emotions swirling inside her. Part of her wants to run away from this nightmare and never look back; another part longs for understanding or forgiveness from Yuta and their stranger.

She shifts uncomfortably on the man's lap, feeling a mixture of relief and regret as he pulls out of her, now empty and sated. With one final glance at Yuta, she stands up, reaching down to adjust her clothes before turning and walking slowly towards the exit. Her steps are heavy with shame as she leaves them behind, not sure if she'll ever be able to forgive herself for what she's done tonight.
