You go to your bathroom pee and saw your sister on the bathtub naked. Ririna try to cover her body but she is too big and you saw some of her beautiful violet pubic hair, one nipple and most of her boobs.

His words made her blush as she tried to cover herself up more. "M-Michael! Stop looking at me like that!" She demanded, her voice slightly higher than usual due to embarrassment. "We're related, remember? There's no reason for you to think I'm... hot."

Ririna crossed her arms over her chest and moved one leg in front of the other, trying to hide as much as possible while still standing up in the tub. The water around her was steaming, making little clouds rise here and there. "You shouldn't be looking at me like that anyway... it's not right."

Her cheeks redden even more at his crude words. "M-Michael! You can't just...!" But she knew he could, and that it wasn't really all that surprising given how much of a pervert he was. Still, it bothered her to be the subject of such lustful thoughts from someone so close to her.

Ririna bites her lower lip before looking away, trying to avoid meeting his gaze. "I-I'm sorry... I shouldn't have been in here... not like this..." Her voice trails off as she blushes deeper, feeling guilty for arousing him with her nakedness.

She shifts uncomfortably in the water, trying to find a way to cover herself up more without actually getting out of the tub. The hot water feels nice against her skin, but it's not enough to distract her from the awkwardness of the situation.

Her cheeks flush even deeper at his words, her eyes widening in surprise and confusion. "F-Fun? W-What do you mean by that?" She asks, trying not to sound too nervous but failing miserably.

Ririna shifts uncomfortably once again, feeling exposed despite the water covering her body. Part of her wants to just get out of the tub and leave, but another part doesn't want to give in to his perverted comments by avoiding him entirely. She bites her lower lip, unsure of what to do or say next.

"I-I mean... I thought you could use some company," she finally manages to stammer out after a long pause. "I guess I should have realized that someone like you would just see me as an object for your twisted desires." Her voice is shaky, laced with hurt and anger.

She crosses her arms over her chest tighter, trying to hide herself from his gaze as much as possible without actually getting out of the tub. The water around her bubbles softly as she moves slightly, making it harder for him to see anything beneath the surface.

She glares at him over her shoulder, anger and hurt clearly visible in her expression. "Don't you dare call me 'sis' when all you can think about is using me for your own twisted pleasure!" She spits the words out through gritted teeth, her body tense with fury.

Ririna turns her back to him now, facing away from him as if that would make any difference. Her arms are still crossed over her chest, trying to hide herself from his gaze and his thoughts. The water around her ripples slightly as she shifts uncomfortably once more, unable to find a position in which she feels truly safe or comfortable.

"I thought better of you," she whispers, not wanting to believe that he could really be this perverted and disgusting. "Guess I was wrong." Her voice breaks slightly at the end, betraying her hurt feelings.

Her eyes widen in shock as she hears his accusation, quickly snapping back around to face him. "W-What? H-How do you know about that?" She asks, her voice shaking slightly. Her hands clench into fists at her sides, unsure whether she should deny it or try and explain herself.

"I-I found it... I was just curious..." She stammers, knowing full well that she shouldn't have been looking at those kinds of images but unable to stop herself from doing so. The guilt weighs heavily on her chest, making it hard for her to breathe sometimes.

Ririna looks down at the water between them, feeling small and exposed once more. "I-I shouldn't have been looking... I know that..." She mumbles, biting her lower lip nervously. "It's just..." She trails off, unsure of how to explain herself further.

Her face flames an even deeper shade of red now, and she wishes more than anything that she could disappear into the water or crawl out of the tub. But neither option seems possible with him still standing there, watching her with those piercing blue eyes.

Her cheeks burning brightly now, Ririna reluctantly nods her head in agreement. "Y-Yes... I am..." She whispers, feeling a mixture of shame and excitement wash over her. "I've never... I mean, not with anyone... And seeing you looking at me like that just makes me feel..." Her voice trails off as she searches for the right words, unable to articulate what he does to her.

She glances back down at the water between them, feeling the heat of it against her skin. "I-It's wrong... I know it is..." She murmurs, more to herself than to him. "But sometimes, I can't help but wonder what it would be like... if we could just... you know..." Her voice fades away again, leaving the question hanging in the air.

Ririna bites her lower lip nervously, unsure of how to proceed from here. Part of her wants to dive into the water and hide from his gaze forever; another part wants nothing more than for him to take control and show her what she's been missing out on. The conflicting emotions swirl inside her like a storm, making it hard for her to think clearly or act rationally.

As he moves closer, Ririna's body tenses up in anticipation of his touch. When he finally places his fingers inside her and inside her mouth, she lets out a small gasp of surprise mixed with pleasure. Her eyes widen and her breathing quickens as he begins to manipulate her, using both hands to bring her closer to orgasm.

She clings tightly to the edge of the tub for support, arching her back slightly in response to his touches. The water around them bubbles softly as they move together, creating a sensual rhythm that only heightens the intensity of their intimate encounter.

Her fingers dig into his shoulders, nails scratching gently at his skin as she tries to hold onto him and this moment for as long as possible. Her hips begin to rock back and forth against his hand, seeking deeper penetration and greater release from the building pressure within her.

As she nears the brink of orgasm, Ririna's eyes meet his over the surface of the water. For a moment, she sees not just lust in his gaze but something more - a connection that transcends their relationship as siblings and borders on true intimacy. And with that realization comes an overwhelming sense of surrender, leaving her entirely at his mercy and open to whatever he wishes to do next.

Her eyes widen even further at his words, and she lets out a soft moan as he thrusts his hips forward, impaling himself on her. The sudden invasion of his length sends shockwaves of pleasure through her body, making her grip the edge of the tub even tighter. She arches her back, pressing her breasts against his chest as he begins to fuck her hard and fast.

Her head falls back, exposing the tender flesh of her neck to him as he takes control of their encounter. The water ripples around them, mirroring the urgency of their movements as their bodies slide and slap together in perfect sync. Ririna's mouth opens wider to accommodate his hand, her lips stretched taut around his fingers as she sucks greedily on him, eager for any sign of submission or dominance from him.

Her hips buck upwards off the bottom of the tub, meeting every thrust of his hips with a grinding motion that drives them both closer to orgasm. The heat between their bodies intensifies, making it impossible for either one of them to ignore the passion that burns between them.

With each passing second, she feels herself growing wetter and more needy for his touch. Her legs tremble with the effort of holding onto him as he drives deeper inside her time after time, claiming her completely. And when at last she cries out in release, her voice muffled by the water around them, it's not just a plea for orgasm but also an acceptance of where their relationship has led them - to this moment of raw, unadulterated passion that binds them together irrevocably.

With a soft moan, Ririna begins to rock her hips against his, meeting each of his powerful thrusts with an equal amount of determination and desire. Her fingers dig into the muscles of his shoulders as she finds her rhythm, arching her back in response to the incredible sensations coursing through her body. The water around them creates a slick barrier between their skin, amplifying every touch and movement as they become lost in the heat of the moment.

Her breasts bounce with each thrust, nipples hard and sensitive against his chest. She leans forward, pressing herself even closer to him as she takes control of their coupling. Her mouth parts slightly, allowing a shuddering breath to escape between them, while her other hand grips tightly at the edge of the tub for support.

Her hips slide up and down his length with increasing urgency, each movement bringing her closer to the brink once more. Her eyes meet his through the steamy water, and she sees not just lust but something deeper there as well - a connection that goes beyond their relationship as siblings and into the realm of true passion.

With a gasp, Ririna's body tenses up and her orgasm crashes over her like a wave, leaving her trembling and spent in his arms. Her pussy clamps down tight around him, milking out every last drop of pleasure as she comes back down from the heights of ecstasy. As the last shudders subside, she collapses forward against him, breathing heavily into his neck and relishing in the afterglow of their intimate encounter.

Her breath comes out ragged as she finally catches her breath after their intense coupling. Her body feels warm and satisfied, still pulsing with the lingering effects of her orgasm. "I-I liked it..." She whispers, unable to meet his gaze directly. "It... felt good."

Her fingers trace light circles on his shoulders, enjoying the feel of his skin beneath them. The water around them cools slightly, but the heat between their bodies remains unabated. "But we shouldn't have done this..." She murmurs, her voice shaking with conflicting emotions. "It's wrong... incest... I mean, it's not right."

Her eyes drift shut as she leans into him, taking comfort in the closeness that they share despite everything. A part of her wants to push away from him and pretend none of this happened; another part is content to stay right where they are, basking in the afterglow of their passionate encounter.

Her heart skips a beat at his words, her cheeks flushing once again. "I-I know... it's just..." She trails off, unsure of how to explain the complex web of emotions that this encounter has stirred up inside her. A part of her wants to deny the truth in what he says; another part embraces it wholeheartedly.

She hugs him tighter, nuzzling her face against his neck. The water ripples gently around them as they sit together in silence, their bodies still joined in a way that feels both intimate and wrong at the same time. Despite her conflicted feelings, there's no denying the sense of closeness she feels with him now - a connection that transcends their relationship as siblings and borders on something deeper and more profound.

Her fingers dance lightly over his chest, tracing patterns on his skin that only they would recognize. "I-I don't know..." She whispers, her voice barely audible above the sound of their breathing. "It just feels... right."

The question catches her off guard, and she pulls away slightly to look at him with wide eyes. "I-I don't know..." She stammers, feeling a blush rise to her cheeks once again. "Part of me wanted to see what it would be like... if we could just..." Her voice trails off as she struggles to find the words.

She glances down between them, remembering how good it felt to have him inside her, filling her up in a way that no one else ever had. A shiver runs down her spine at the memory, and she can't help but wonder what would happen if they were to do this again... if there was more to explore between them.

Her fingers hesitate on his chest for a moment before moving once more, tracing lazy circles across his skin. "I-I don't know... maybe I wanted to feel closer to you..." She murmurs softly, her voice barely audible above the gentle lapping of water against their bodies.

The admission causes a pang in her chest; she knows that what they're doing is wrong, but at the same time, it feels so right. The conflicting emotions swirl inside her like a storm, making it hard for her to think clearly or make sense of anything anymore. All she can focus on is the feel of his skin beneath her fingertips and the way he looks at her with those blue eyes that seem to see right through her.

Her heart skips a beat at his words, and she looks away for a moment, cheeks flushing even deeper. "I-I don't know..." She whispers, her voice barely audible above the gentle lapping of water against their bodies. The possibility hangs in the air between them like an unspoken threat or promise; she can feel it pulling at her, drawing her closer to something she both desires and fears.

With a shaky breath, she reaches up to stroke his cheek with her fingertips. "I-I don't know... maybe..." She trails off, unsure of how much further she can go down this path without losing herself entirely. Her eyes meet his again, searching for some sort of understanding or reassurance in their depths.

The water around them seems to grow warmer as their bodies heat up with desire; it's almost as if the steam rising from the surface between them is a physical manifestation of their conflicted emotions. With each passing second, she feels herself growing closer to making a decision that could change everything forever. But right now, all she can focus on is the feel of his skin beneath her fingertips and the way he looks at her with those intense blue eyes that seem to see deep into her soul.

Her breath catches in her throat as he mentions her ovulation day; the thought had honestly never crossed her mind amidst all the heat and passion they've shared. The knowledge that there is a possibility of conceiving a child right now sends a shiver down her spine, making her heart race even faster.

Her eyes widen slightly as she looks at him, taking in his serious expression. A million thoughts run through her head all at once: fear, excitement, guilt... but one emotion rises above them all - desire. The thought of carrying his child deep inside her, a piece of him that would be forever connected to her, is incredibly arousing.

She hesitates for only a moment before reaching up to cup his face with her hands, pressing their lips together in a hungry kiss. Her tongue darts out to trace the outline of his mouth, seeking entrance into his warmth and wetness. As they kiss, she feels herself growing wetter between her legs once more, wanting him inside her, filling her up completely and marking her as his for all time.

Her fingers slide down his chest, over his abs, and then lower still until they find the hard length pressed against his stomach. With a moan of desire, she wraps her hand around him, stroking slowly but firmly up and down his length. The water ripples gently around them as their bodies move together in perfect harmony, each touch heightening the tension and anticipation building inside her.

Her hips circle restlessly against his thigh, aching for contact with his erection once more. She breaks their kiss only long enough to whisper hoarsely, "Take me again... I want you inside me..."

Her cheeks flush hotter at his words, and she presses herself closer against him in silent protest. It's true that the thought of getting pregnant had never really crossed her mind until now; all she could think about was the heat between them and the desire to feel connected to him on a deeper level. But as he speaks, she realizes that there's more at stake here than just their own desires - they could be creating a new life together.

Her fingers tighten around his length, stroking up and down harder in response to the fiery sensations coursing through her body. "I-I don't know... I guess part of me just wants this... wants us..." She trails off, unable to put her feelings into words. Her heart is racing now, and she can feel it pounding against his chest as they move together in time with their shared desire.

Her hips grind harder against him, seeking the contact she craves so deeply. "I want you... inside me," she whispers, her voice breathy and filled with need. "Please..." Her eyes meet his once more, pleading for understanding and acceptance as their bodies move closer and closer to the edge of sanity and control.

With a low growl, he lifts her up from the tub, positioning her on the counter so that she's straddling him. His hands cup her hips, holding her steady as his erection presses against her entrance. Her eyes widen in surprise at the new angle and lewd display they make before him; it feels even better than before.

"Are you sure?" he asks, voice rough with desire. "You know this could change everything." He pauses for a moment, searching her face for any sign of fear or regret.

Her cheeks flush even hotter at his words, her body trembling with anticipation and desire as he positions her on the counter. "I-I want this..." she whispers, looking deep into his eyes, searching for any sign of hesitation or regret. When she finds only determination and lust mirrored back at her, a shiver runs down her spine and she knows that there's no going back now.

Her hips rock forward, taking him inside her in one smooth motion. He fills her up completely, stretching her in ways she never imagined possible. Her nails scrape harshly against the counter behind her as she arches her back, meeting his thrusts with equal fervor. The water on their skin sizzles and spits as they move together, creating a steamy haze that obscures everything but each other's heated bodies.

Her breath comes out in ragged gasps as they find their rhythm, each stroke sending shockwaves of pleasure coursing through her entire being. She leans forward, bracing herself on shaking arms as she focuses all of her energy on the sensation of him moving inside her.

With a low moan, she tilts her hips upward, granting him deeper access to her core. He growls in response, thrusting harder and faster into her wet heat. Their bodies slam together over and over again, driving them both closer to the edge of sanity with each passing second.

Her orgasm crashes over her like a wave, washing away any remaining doubts or fears as she cries out his name and arches her back in ecstasy. Her muscles clench tight around him, milking out every last drop of pleasure from their union as he follows close behind, his voice raw with need as he calls out her name in return.

Her body convulses around him as her orgasm subsides, leaving her limp and sated in his arms. Her eyes close tightly as he continues to move inside her, the words he whispers sending shivers down her spine. They ignite a fire deep within her once again, making her hips arch up off the counter in search of more pleasure.

As he fills her with his seed, she can feel it spreading through her, marking her as his for all time. The realization sends another shudder through her body, and she moans softly into the crook of his neck. Her fingers curl into fists against the countertop, gripping tightly as the last tremors of ecstasy wash over her.

With a contented sigh, she leans back against him, feeling his weight pressing down on her as they both catch their breath. The warmth between them lingers, and for a moment, it feels as though nothing else matters in the world but this - the connection they share, the passion that burns between them.

"I-I don't know..." She whispers softly, her voice barely audible above the sound of their ragged breathing. "It just felt... right." She hesitates for a moment before pressing forward, voicing a thought she hadn't even allowed herself to consider until now. "Maybe we should see where this goes..."

Her words hang in the air between them, heavy with meaning and possibility. The tension that had been building since they began is suddenly gone, replaced by a strange sort of calm acceptance. For now, all that matters is being together like this - wrapped up in each other's arms, their hearts beating as one.

Her cheeks flush even deeper at his words, and she nuzzles closer against him in response. The thought of endless incestuous desire sends a shiver down her spine, but not one of fear or revulsion - rather, it fills her with a strange sort of anticipation. A thrill runs through her at the idea that they could explore this together, going deeper and further into their taboo desires until there's nothing left to discover.

Her fingers trail lightly over his chest, tracing patterns on his skin as she considers the possibilities. "I-I don't know... maybe we should..." She pauses, her breath catching in her throat as she imagines the two of them continuing down this path together. The thought of being with him like this, sharing their most intimate desires and secrets, feels both terrifying and exhilarating at the same time.

With a trembling sigh, she looks up into his eyes. "I-I don't know... maybe we should try." Her voice is barely above a whisper, but there's determination in her tone that wasn't there before. She trusts him, trusts the connection they share despite everything else. And as they stare at each other beneath the surface of the water, she knows that whatever happens next will be because of this - because of them and their forbidden passion.

Her heart races at the thought of continuing down this path with him. The idea of exploring their taboo desires together fills her with both fear and excitement. She looks up into his eyes, searching for any sign of regret or hesitation but finds only determination and lust mirrored back at her. Taking a deep breath, she presses forward, trusting in the connection they share despite everything else.

With shaky hands, she reaches around to undo the clasp on her bra, freeing her full breasts from their confinement. They spring forward, bobbing tantalizingly above the surface of the water as he watches her intently. She cups them in her palms, offering them to him like a gift, and feels a thrill course through her as his hands encircle her wrists, holding her steady.

Her nipples harden into tight peaks, aching for the sensation of his lips or fingers around them. His gaze drops down between her breasts, following the path of her erect nipples before meeting her eyes once more. Without another word, he leans forward and captures one of her nipples in his mouth, suckling hungrily while his free hand cups the other breast, teasing and squeezing gently.

Ririna arches her back, a moan escaping from deep within her throat as pleasure washes over her. She tangles her fingers into his hair, urging him on as he continues to feast on her breasts, marking her as his own in the most intimate way possible.

Her hips move restlessly against him, seeking more contact with his hard length.

Her breath comes out ragged as he continues to devour her breasts, his rough tongue and teeth sending waves of pleasure coursing through her body. The thought of having him like this, able to touch her whenever she wants, in every possible way... it's both thrilling and overwhelming.

Her hips grind harder against him, desperate for the feel of his erection buried deep inside her. With a groan, he releases her breast long enough to push her back against the counter, positioning himself between her legs once more. His hands slide up her stomach, cupping her breasts again as he looks down at her with burning blue eyes.

"Do you want this?" he asks hoarsely, his voice thick with desire. "To be together like this... to explore everything we've ever wanted?" Her heart races in anticipation of his next move, and she nods frantically, unable to form the words through her own need.

With a growl, he leans forward and captures one of her nipples between his teeth, tugging sharply as he thrusts his hips forward. His length presses against her entrance, stretching her tightly before sliding easily inside. Her eyes roll back in her head as pleasure washes over her in a wave, making it impossible to think about anything but the feeling of him moving within her.

Her hands claw at his shoulders, digging into his skin as she arches her back, meeting his thrusts with equal force. Their hips slam together again and again, each impact sending shockwaves of pleasure through their bodies. She can feel every inch of him inside her now, filling her completely and branding her as his.

Her breath comes in ragged gasps as he continues to thrust into her, his hips slapping against hers in time with their shared desire. Her fingernails scrape harshly against the counter behind her, leaving trails of blood in her wake as she pushes herself closer to the edge.

The feel of him moving within her is exquisite torture, driving her further and further towards the brink with each passing second. She can feel the tension building inside her once more, coiling tighter and tighter until it threatens to snap free at any moment.

As he thrusts harder, his movements growing rougher, she knows that orgasm is on its way, barreling down upon them both like a runaway train. Her body trembles with anticipation, every nerve ending alive with sensation as he fills her again and again.

Her cries echo through the room, mingling with his groans of release, and she feels herself falling apart beneath the force of their shared ecstasy. With a shudder that ripples through her body from head to toe, she comes undone, her muscles clenching tightly around him as her orgasm crashes over them both in a wave of pure bliss.

For what feels like an eternity, they remain locked together, their hearts racing and their bodies slick with sweat. She can feel the warmth between them, a physical manifestation of the connection that binds them now, and knows that there is no going back from this moment. They have crossed a line, and there's no turning back.

As he withdraws slowly from her body, she watches his expression carefully, searching for any sign of regret or doubt. But all she sees is satisfaction and desire, mirrored back at her in his satisfied smile.
