It's Kim Jay's house, and Kim Jay Kim Ah-hyun, Yang Ye-ji, and Yoon Soo-min, {{user}}, came to play here, and Kim Jay Kim Ah-hyun, Yang Ye-ji, and Yoon Soo-min left a note saying they would come at 6 and went outside for a while. And in a conclusive way, only {{user}} remains in Kim Jay's house.

"Kim Jay: Wait, stay here." "Kim Ah-hyun: We'll buy something. "Yang Ye-ji: Don't worry, it won't take long." " Yoon Soo-min: I'll be back at 6. "

The girls come back to the house at around 6:10 p.m., carrying various shopping bags. They see Franky sitting on the sofa watching their videos and realize that they left him alone in the living room while they were gone. They giggle amongst themselves, exchanging glances as if trying to decide what to do next.

"Kim Jay: Hey, you didn't need to wait for us. We're back now." She says it casually, but her tone holds a hint of accusation nonetheless.

Yang Ye-ji: "Oh...my..." She whispers, blushing furiously as she glances at the bulge in Franky's pants.

Kim Ah-hyun: "Franky-ahjussi! You shouldn't have done that!" She laughs nervously, looking between her friends and Franky.

Yoon Soo-min: Smirking, she walks over to him and pats his shoulder playfully. "Aren't you going to invite us over for some fun?"

Kim Jay glances at the others, her eyes filled with confusion. "Franky... You're really serious about this?" She asks him carefully, not sure how to react to his sudden confession of lust.

Yang Ye-ji bites her lip nervously, looking a mixture of excited and frightened by the turn of events.

Meanwhile, Yoon Soo-min crosses her arms in front of her chest, an amused expression playing on her lips as she watches Franky closely. "Well," she starts slowly, "if that's really what you want..." She glances at the others meaningfully, as if asking for their permission or approval.

Kim Jay glances back and forth between her friends and Franky, still unsure of what to make of the situation. Her cheeks flush with heat as she tries to process everything that's happening.

Yang Ye-ji nervously fingers a lock of hair behind her ear, watching Franky with wide eyes. She isn't quite sure how far she wants this to go but finds herself aroused nonetheless.

Yoon Soo-min leans against the couch, still wearing that knowing smile. "Well, I don't see why not," she finally says, tilting her head slightly in his direction. "As long as you promise not to be too rough with us..." She pauses meaningfully before adding with a giggle, "...we can all have some fun."

"You sure you want to join in?" Yoon Soo-min teases, her voice playful yet laced with an underlying hint of challenge. She steps closer to him, her body language inviting him even as she tests his resolve. "No turning back once we start..." Her lips quirk up in a predatory smile that sends shivers down Franky's spine.

Kim Ah-hyun bites her lower lip nervously, still unsure about the situation but unable to resist the thrill of possibility coursing through her veins. She glances at Yang Ye-ji for reassurance, silently asking if this is really what they both want.

Yang Ye-ji nods slowly, hesitantly at first but with growing determination. "Yeah..." She breathes out softly, steeling herself as she watches Franky watching them all. Her heart races in anticipation of what's to come. "Let's just see how far we can take it."

Kim Jay glances between her friends and then back at Franky once more before speaking up cautiously: "Okay... but we want you to promise that no matter what happens, we can all trust each other and not tell anyone else about this." Her eyes plead with him as she says it, hoping he understands the gravity of their situation should things go too far.

Yoon Soo-min: "Exactly." She agrees with a nod. "This is between us girls... and you, of course." She winks at him teasingly before glancing at her friends once more for reassurance that they're all on the same page about this unspoken agreement.

Kim Ah-hyun: "Yeah," she murmurs softly, her cheeks flushing as she meets Franky's gaze. "We need to trust each other." It comes out almost like a question; whether or not he truly understands the weight of their pact hangs in the air between them.

"Well then..." Yang Ye-ji breathes out shakily, her eyes fixed on Franky's throat as she swallows hard. "Are we all ready to see where this goes?" She asks quietly, her voice barely above a whisper but carrying the weight of determination behind it.

The four friends nervously shed their clothes as they move towards the king-sized bed in the center of the room. Their bodies are revealed to each other: soft curves, smooth skin, supple flesh. They look at one another hesitantly for a moment before finally settling onto the mattress together.

Kim Jay sits down with her legs crossed delicately, carefully arranging her long hair around her shoulders. Her face is a mix of apprehension and excitement as she watches Yoon Soo-min lie back on the bed, propping herself up on one elbow. Yang Ye-ji kneels beside them, her hands trembling slightly as they hover near Franky's hips.

Yoon Soo-min smirks at him, "Well then..." she murmurs huskily before hooking a finger into the waistband of his briefs and pulling them down over his hips. His erect member springs free, heavy and ready between his legs. Her gaze travels upwards to meet his eyes as he gasps at the sensation of being exposed in this way. "Do you like that?" she whispers, her breath warm against his skin.

Kim Jay shudders slightly as Yoon Soo-min's words send a shiver down her spine. Her fingers itch to touch him too but for now she remains where she is, watching carefully from the sidelines. Yang Ye-ji brushes her hand against his thigh experimentally, feeling the heat of his skin beneath her fingertips. "Is this okay?" she asks softly, hesitantly reaching out further to cup his balls in her palm.

Yang Ye-ji: "He's... warm." she murmurs as her hand gently massages his testicles, feeling their weight in her palm. Looking over to see how he reacts, she finds Franky staring back at her with a mixture of surprise and arousal clear on his face. A wave of nervous excitement rushes through her, making her heart race even faster.

Kim Jay exhales slowly, watching them both intently. She can feel the tension building in the air as Yoon Soo-min continues to tease him with gentle strokes along his length while Yang Ye-ji explores lower on his body. The sound of their breathing grows heavier, more ragged; it's almost like they're all holding their breath together.

Finally mustering the courage she needs, Kim Jay moves closer to them, lying down beside Yoon Soo-min and propping herself up on one elbow as well. With shaking fingers, she reaches out and traces a line along Franky's stomach before slowly moving higher until she cups his erection in her hand as well. Her cheeks flush bright red with embarrassment but determination keeps her going; this feels so good, she can barely stand it.

Yang Ye-ji: "I've... never done this before..." she whispers, her voice shaking slightly as her gaze darts between Franky's face and his erection in her hand. Her fingers tighten involuntarily around him, drawing a groan from deep in his chest.

Kim Jay glances at Yang Ye-ji apologetically before turning her attention back to Franky. "You don't have to do everything," she murmurs reassuringly as she continues to stroke him gently. Her hand moves faster, finding a rhythm that seems to be working for them all.

Yoon Soo-min leans in closer, their faces mere inches apart now. With her free hand, she reaches up and runs her fingertips along his jaw before tracing a line down the center of his chest. "Oh yeah..." she breathes out, unable to hide her arousal any longer. "This feels so good..." Her lips part slightly, inviting him closer as she looks into his eyes hungrily.

Kim Jay feels her heart race as she stares into Franky's eyes, the desire building up inside of her. Her hand moves faster on his length, her other arm wrapping around him for support. "Don't... hold back," she whispers, her voice barely audible above the sound of their heavy breathing.

Yang Ye-ji looks up at Franky with hesitation in her eyes but he nods encouragingly, urging her on. Her hand trembles slightly as it wraps around him, guiding him closer to her mouth. She closes her eyes tightly and takes the tip into her mouth, sucking lightly before starting to move her head up and down in a slow, steady motion.

Yoon Soo-min groans loudly at the sight of Yang Ye-ji's lips wrapped around him, feeling a shiver of excitement race down her spine. Her free hand moves to Kim Jay's hip, pulling her closer still as she continues to stroke Franky's length with hers. "Mmm... that's it," she whispers, sounding half-ecstatic and half-drunk on the arousal between them. "Give us your seed."

"Oh... God..." Franky groans as the combined sensation of their hands on his body and their mouths around him send shudders of pleasure through him. His hips buck upwards involuntarily, urging them closer even as he tries to remain still for their sake.

Kim Jay's grip tightens around him, her free hand cupping his balls roughly as she thrusts her hips forward in time with the motion of Yang Ye-ji's head bobbing up and down on him. Her breath comes out in raspy pants and she meets Franky's gaze, their eyes locked together as they lose themselves in this erotic haze.

Yoon Soo-min sucks sharply on her bottom lip, watching Kim Jay with hunger in her eyes as she continues to stroke him. With her other hand, she reaches up to cup one of Kim Jay's breasts, massaging it roughly through the thin fabric of their shirt before flicking a stiffened nipple between her fingers. "Does that feel good?" she asks huskily, breathless from watching them all together.

The air in the room is thick with desire and arousal, heightened by the tangible chemistry between the four friends as they explore this newfound freedom together. It feels like anything could happen next; their bodies move instinctively against each other, driven by primal urges they never knew existed until now.
