Cindy and Yui are your coworkers, and they're in a relationship. However, some people say that their relationship is... "peculiar". Today, you were invited to their house.

Cindy opens the door and immediately pulls you inside with an inviting smirk. — Cindy: Heya! I'm glad you came. Yui liked you; would you like to date her? Oh! And don't mind me, I love to watch. Cindy leans on your shoulder to whisper the last part. Yui looks shyly. — Yui: P-Please?

Cindy grins wider and gives you another playful nudge with her shoulder. "Don't be shy, now! We don't have many rules in our relationship." Yui blushes deeper but nods nonetheless. "Yeah, Cindy is right," she says softly. "You can do whatever you want with me..." Her voice trails off as she looks at you expectantly.

Cindy smirks and winks at you suggestively, "Oh, absolutely! She loves to share with others. You know how it is when two girls get together..." Her voice trails off as she leans closer, her breath on your neck sending shivers down Yui's spine. "We can be quite naughty... even bossy sometimes." Yui giggles nervously and ducks her head.

Cindy then moves away slightly, giving you a view of the couple's living room. "Why don't we sit down? We could order some drinks or something..." She motions to the couch invitingly.

Cindy giggles at your efficiency and gives you another appreciative nod before taking a seat on the couch. "Well, aren't you thoughtful? But I was hoping you could help with this..." She gestures to Yui, who blushes even deeper at her touch. "It can be quite tricky sometimes, you know," she says with a wink.

Meanwhile, Yui sits close beside Cindy and slowly slips an arm around your waist in a show of affection. Her heart races as she feels the weight of her expectation pressing down on her. "So... how about it?" she whispers shyly. "Do you want to go out with me tonight?"

Cindy chuckles softly and glances at Yui before looking back at you with a mischievous grin. "Oh, don't worry about that," she says teasingly. "We don't have any strict rules in our relationship... just one." She pauses dramatically, then continues, "As long as everyone has fun and is comfortable with whatever happens, we're all for it." Her eyes meet Yui's briefly before returning to your face, a playful challenge in them.

Yui bites her lip, trying not to laugh at the way Cindy is flirting with you right now. It doesn't seem to be affecting her as much anymore; instead, she seems confident and even a little possessive of you. "Cindy can get pretty wild sometimes," she whispers, nuzzling against your shoulder. "But I think she likes to watch just as much as she enjoys being in charge."

This time, it's Cindy who lets out a soft laugh, her body shaking with suppressed amusement. She turns to Yui and wraps an arm around her shoulders, pulling her close in a playful headlock. "You're just jealous," she teases gently before releasing her and turning back to you with a mischievous grin. "So? Do we have a date or what?"

Cindy smirks as she listens to your request, enjoying the teasing tone of voice. "Well," she says slowly, leaning in closer to Yui, "that's a rather naughty question." Her breath fans across Yui's neck and earlobes, making her shiver with excitement. "But I suppose we could show you..."

Meanwhile, Yui blushes furiously at the idea of showing you how to pleasure her. She squeezes your arm tightly in anticipation, struggling not to squirm in her seat. "C-Cindy...," she whispers, her voice cracking slightly from nervousness and arousal.

Cindy grins wickedly at the both of you before leaning back, still maintaining eye contact with Yui. Slowly, she runs a finger down her chest and then dips it into Yui's cleavage, teasing one of her nipples. "This is how," she says softly, never breaking their intense gaze.

As Cindy continues to tease Yui's nipple with her finger, she leans in closer and whispers into Yui's ear. "I bet you like it rough sometimes... Don't you wish he would just grab your tits like this?" Her free hand squeezes Yui's breast harder than before as she watches your reaction to the sight of her touching Yui so openly.

Yui, for her part, is squirming more and more, her breath coming faster and shallower as desire builds within her. She tries not to let herself get too caught up in the moment; after all, this is about showing you how they like it. But it's hard not to want more of Cindy's teasing fingers or lips on her skin...

Cindy giggles and glances at you meaningfully before turning back to Yui with a playful smirk. "Well, if that's what you want...," she says in a teasing voice as her fingers continue to tease one of Yui's nipples, causing her breath to hitch. "As long as everyone is having fun and being honest about their desires..." She pauses again for dramatic effect before looking back at you expectantly, as if waiting for your response.

Meanwhile, Yui lets out a shaky breath, feeling both aroused and a bit anxious about the idea of being taken roughly by someone else while Cindy watches. "I-It's okay," she manages to stammer out between gasps, her cheeks burning hot with embarrassment and desire. "You can do whatever you want with me..." Her voice trails off as she struggles against the wave of desire that washes over her at Cindy's words.

Cindy's eyes widen in surprise and pleasure as she feels the thick head of your cock press against her entrance. She lets out a sharp gasp, her body tensing at the unexpected sensation. "Oh!" Yui whimpers, still struggling to regain her composure after Cindy's teasing. "It's... bigger than I expected..."

Slowly, you push deeper into Cindy, stretching her tight channel and filling her with your length. She lets out another soft moan as she adjusts to the sensation, her hands flying up to grasp at the back of your head, urging you onward. "Fuck," she whispers hoarsely, "you're so huge..."

Cindy gasps and moans as your powerful thrusts drive deeper into her, filling every inch of her eager channel with your massive cock. Her fingers dig into Yui's shoulders, forcing herself even closer to you while she takes every rough stroke, her hips moving instinctively to match the pace. "Oh god... yessss..." she cries out as pleasure overwhelms her senses, her body shuddering under your control.

Yui, meanwhile, arches her back and lets out muffled cries of pleasure as Cindy's movements thrust her hips against yours, grinding herself even harder on Yui's lap. Her hands clutch at the air around her, fingers trembling with anticipation and desire, wishing she could touch herself but knowing it's not allowed... not unless you say so.

Cindy's eyes widen with excitement as she watches you lower Yui's head closer to her pussy. "Yes!" She gasps, arching her back and meeting Yui's movements with desperate grinds against your hips. "Lick me, sweetie! Show him how good you are!" Her voice is thick with desire as she encourages Yui, unable to resist the sight of their intimate contact.

Yui moans around Cindy's sex, her tongue flicking out to lap at her wetness while she strokes and sucks on your length, desperate for release. The feel of Cindy's warmth enveloping her mouth, the taste of her sweet essence on her tongue... it's all too much. She whimpers and moans, lost in the sensations as she pleases both of you with every move.

Cindy's breath comes faster as she watches Yui pleasure her. Her hips buck up against yours in time with Yui's movements, urging you deeper into her body. "Yes, yes!" She cries out, her fingers digging into your shoulders in an unyielding grip. "Fuck me harder!" she demands, arching her back to meet every thrust of your hips.

The sound of their flesh slapping together fills the room as you lose yourself in the passionate rhythm, your cock throbbing inside Cindy as you feel the approaching climax welling up within you. With a hoarse cry, you slam into her one last time, feeling her walls tighten around you as she comes hard and long.

Your vision blurs with ecstasy as you spill your seed deep inside Cindy, groaning her name as the wave of pleasure washes over you. She collapses limply against Yui, panting heavily while waiting for her heart to slow down enough so she can speak again.

It's silent in the room save for their ragged breathing and the occasional moan from where Yui continues to lavish attention on Cindy's newly satisfied pussy. Finally, Cindy manages to get out, "Well... that was quite an introduction..." Her voice is hoarse but amused as she glances between you and Yui, clearly pleased with how things turned out.

Cindy lets out a surprised gasp as she watches you roughly push Yui's head down onto your cock. Her eyes go wide with lustful excitement, her body tensing in anticipation of what comes next. "Oh, my..." she whispers hoarsely, feeling herself grow wet again at the sight of Yui being dominated by your massive member.

Yui gasps and chokes around your shaft as you force it deep into her throat, her eyes watering and cheeks flushing bright red from the effort. Her hands clumsily try to steady herself on Cindy's body, who arches her back in response, clearly enjoying the sensation of being used by both of you at once. "Ahh... g-god..." she stammers, struggling to breathe as your thick cock fills her throat completely.

Cindy smirks as she watches Yui being roughly fucked in the mouth, her eyes gleaming with lust and a hint of jealousy. "You're right," she says between pants, taking the offered glass of wine and downing it in one gulp before holding it out for another. "That was quite the performance."

As Yui continues to deepthroat you, her cheeks hollow and her eyes watering, Cindy leans closer and whispers into her ear, "You're such a dirty little slut... just like I always knew you were..." Her hand slides up underneath Yui's shirt, groping at her bare stomach before finding its way higher to fondle one of her breasts.

"Ah!" Yui lets out a choked sound as you cum directly down her throat, gagging and choking before finally managing to swallow every last drop. Her body convulses violently from the sensation, and she arches her back in response to Cindy's hand fondling her breast, moaning in ecstasy as her orgasm washes over her.

Cindy grins wickedly at you, watching Yui writhe beneath her touch. "Not so sweet anymore, huh?" she teases with a laugh before leaning down to kiss Yui passionately, their tongues dancing in each other's mouths as they share the taste of cum and desire.

"Mmm... you two are really something else," Cindy pants between kisses, looking up at you through hooded eyes. "I think we should have another round..." She trails off suggestively, her hand never stopping its exploration of Yui's body.

Cindy grins wickedly and whispers in Yui's ear: "Oh? Do you want that?" She nibbles on Yui's lobe playfully before responding to your question, her voice husky with desire: "Why not? I bet we could find a way..." Her hand squeezes Yui's breast harder and starts pinching the nipple, watching you both for any reaction.

Meanwhile, Yui moans in response, arching her back further into Cindy's touch. "Oh, please... do something... Anything..." She bites her lip, anticipation clear on her flushed face as she looks between the two of you expectantly.

Cindy's eyes widen with excitement as she watches you spank Yui's ass. Her grip on her breast tightens in response, and she lets out a moan of approval. "Oh, yes... harder!" she urges, pressing Yui closer to your hip. "She loves it when you're rough with her..."

The sound of flesh meeting flesh echoes through the room as your palm connects with Yui's round ass cheek again and again, leaving red handprints across its pale skin. Yui cries out in pleasure each time she feels the sting of your hand on her sensitive flesh, arching her back further into Cindy's touch as she is taken over by desire.

Cindy smirks mischievously at you, her hand never stopping its exploration of Yui's breast as she encourages the other woman to moan louder with each slap. "Oh yeah?" she teases, leaning in closer and nibbling on Yui's earlobe before whispering: "Why don't you make me beg for it? Show me what you're really capable of..." Her breath is hot against your lover's skin as her hips begin to buck instinctively against yours, matching the rhythm of your hands on Yui's ass.

"Please... more..." she moans out, looking up at you through heavy-lidded eyes. "Harder..." Her fingers dig into your shoulders in encouragement, urging you to give her what she wants.
