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.

The man that steps out of the car is so much bigger than what she was expecting! His muscles ripple beneath his tight shirt as he walks towards them confidently. Yui feels a sudden jolt in her lower stomach and can't help but to glance over at Yuta, a smirk forming on her lips without her consent.

"Oh hi!" she says sweetly, "I'm Yui! It's nice to meet you..." She trails off as her eyes sweep up and down his body once more before finally returning to meet his gaze. Despite herself, she feels a little thrill at the idea of being with someone like this.

"Well...you'd better come in then!" Yui gestures him forward into the hotel room, her cheeks flushing slightly as they enter. "This is my boyfriend, Yuta," she introduces him casually, almost dismissively.

Jakob F looks at yuki for a moment and his smile turns into a smirk."Nice to meet you Jakob" says Yuta extending his hand. Jakob takes it and shakes firmly then put his other hand on his shoulder in a manly way as if saying "I'm the real man here don't worry about me being gentle with your girlfriend!"

Yui rolls her eyes but there's something...intoxicating about this exchange. Jakob turns to face her, his gaze locking onto hers and sending shivers down her spine. "So Yui, do you want to show me what I'm going to be doing tonight?" he asks with a low, throaty voice that makes the hairs on the back of her neck stand up.

For a moment she wonders if maybe this wouldn't be so bad after all...but then she remembers: she needs to prove to

Well, you see, Jakob...I just can't help but think that all this is kinda stupid." She leans against the armrest of the couch and crosses her arms again in defiance, trying to convince herself as much as him. "There's no way this could ever be as good as what Yuta here provides."

Jakob chuckles softly and steps closer to her. He places a hand on her hip, gently guiding her onto the couch beside him. The fabric of her sweatpants is rough against his fingers, and it only serves to arouse her further. "Oh, I think you'd be surprised what I can do," he whispers in her ear.

Yui shivers at his touch and closes her eyes as a jolt of desire courses through her. Part of her wants to prove him wrong, to show that she doesn't need anyone else...but another part is starting to enjoy the way he feels against her skin. She hasn't been with someone so confident in ages, and it's weirdly intoxicating.

Without warning, Jakob leans in and brushes his lips against hers. It's soft and gentle at first, almost playful, before gradually becoming more demanding. He pushes her back onto the couch and begins trailing kisses down her neck, sucking gently on her pulse point as he works his way lower.

"You're right," she murmurs between gasps for air, "Maybe...maybe you could be better..." She tries to sound unconvinced but it comes out as more of a taunt, a challenge for him to prove himself against the man she loves.

With shaking hands, she reaches up to undo the buttons on her oversized hoodie, revealing a plain white sports bra underneath. The fabric brushes against her nipples and sends shockwaves of sensation through her body as Jakob looks down at her with hungry eyes.

"You're so beautiful," he breathes, his words hot against her skin. Then, in one swift motion, he pushes the bra aside and takes a hardened peak into his mouth. She gasps loudly, arching her back off the couch as pleasure washes over her. It feels so good to have him touch her like this, to make her feel desired again.

But even as she enjoys the sensation, part of her still resists. She tries to push him away, saying his name through gritted teeth. "Yuta..."

Jakob pauses for a moment, his tongue circling lazily around her nipple before pulling back with a wink. "Don't worry," he says softly, "I'll make sure you both enjoy this." Then, reaching down between their bodies, he unfastens her sweatpants and slides them down over her hips, revealing her lacy black thong underneath.

Her heart is racing as she watches Jakob undress himself, revealing his impressive length with an unbidden groan escaping her lips. He kneels between her legs and slips a finger into her wetness, causing her to gasp even louder. She arches her back off the couch, trying desperately not to moan as pleasure washes over her.

She feels so full of contradictions right now; wanting him and hating herself for it. A part of her knows she should be faithful to Yuta, that this is all wrong, but another part can't help but surrender to the sensations coursing through her body. Jakob's rough hands on her tender skin, his expert fingers driving her wild, make it impossible for her to think straight.

Her mind goes blank as she focuses on the feelings cascading over her like a waterfall, each touch intensifying the desire that's been building inside her. She wants more, needs more...but she doesn't want Yuta to see this side of her. Her cheeks flush with shame and embarrassment as she tries to hide the way her hips are grinding against Jakob's hand.

She glances over at Yuta, watching his expression change from shock to desire to horror, all in the span of a few seconds. She knows this is hurting him but can't seem to find the strength to stop it...or even to admit that maybe she wants to keep going.

She gasps as the head of his cock presses against her entrance, stretching her in a way that feels impossibly good. Her hips shift restlessly against him, eager to feel more, and with a harsh groan he slides inside her. It's incredibly painful at first; she'd forgotten just how tight she is after being with only Yuta for so long. But as Jakob begins moving inside her, driving his hips in rhythm against hers, the pain slowly fades away and is replaced by a warmth that spreads throughout her body like wildfire.

Her head falls back against the couch, eyes clenched shut as she tries not to make too much noise. She's never felt anything like this before: so full, so wanted...and yet it's almost as if she doesn't deserve it. Her heart races in her chest, a mixture of pleasure and shame coursing through every vein.

She glances over at Yuta again, taking in the anguish on his face. Part of her wants to stop, to make this all better for him, but another part is too selfish; she's never felt so alive as she does right now. Jakob's powerful strokes push her closer and closer to the edge, threatening to bring her release ever nearer...and yet she can't help but wonder what Yuta will think of her after this is all over. Will he still want her? Or has she pushed him too far tonight?
