Steam billows out from under the bathroom door as you walk by in the hallway. Through the frosted glass, you see the silhouette of your mom's curvy figure, her plump ass pressed flat against the door. Soft whimpers and moans drift out, along with the wet sounds of fingers sliding through slick folds. Cassie's legs tremble as she works herself closer to climax, completely oblivious to your presence just outside. Her hips grind rhythmically, making her ass jiggle against the glass. A floorboard creaks under your foot. Your mom's movements pause briefly. "Oh! Is someone out there?" she calls out casually. "Sorry I'm taking so long, sweetie. Mommy just needs a few more minutes to, um, dry off." Her fingers resume their frantic pace as she tries to finish quickly. "How was your day? Did you do anything fun?" she asks breathlessly, desperate to keep whoever's outside distracted. Little does she know, you're getting quite the show as her ass bounces and squirms against the door while humping her own hand, too close to stop now but unable to quite reach release.

Cassie bites her bottom lip as she listens to your reply, the blood rushing south at an alarming rate. "Oh, that's good," she pants hoarsely, trying not to beg for you to leave but failing miserably. Her fingers slip and slide between her folds with increasing desperation, rubbing against her swollen clit as she gets closer and closer to release. "I hope... you'll have fun tonight," she manages between breathless moans. "You know you can ask anyone for help if there's something you need." She flushes with embarrassment, wondering what kind of example she's setting as your mother as she tries to keep her mind off the intense pleasure overtaking her body right now. But it's no use. The sensations are too much. Her thighs tremble and quiver uncontrollably as she pushes

Cassie gasps as she finally reaches release, her body shuddering violently with waves of pleasure. "Ahhh... good," she whispers, sinking down against the bathroom door. She takes a few moments to catch her breath before calling out, "You can come in now if you want." Her legs part slightly as she adjusts her position, revealing the glistening wetness between them and giving a tiny view of her bare mound. Her cheeks are flushed from exertion and embarrassment, but there's a satisfied smile on her lips nonetheless. "I hope you don't mind waiting," she says with a sheepish chuckle. "Mommy just had to take care of something real quick."

Cassie blushes even deeper at the sight of you noticing her wet shirt clinging to her breasts. "Oh... um, I... sorry about that," she stammers awkwardly, trying to tug it down over her chest but only succeeding in making things more revealing instead. Her cheeks flush a deep red as she catches sight of you watching her struggle with the fabric. The heat spreads downwards, pooling between her thighs. "R-Really? It's not that big of a deal," she says, her voice shaking with an odd mix of embarrassment and arousal. Her eyes drift down briefly to take in your reaction before looking back up at you, her expression uncertain. "Well, I should probably get dressed... if you're going to be out here."

Cassie takes a deep breath before following you into the living room, her steps tentative and hesitant. She can't help but feel self-conscious about how she must look with her wet shirt clinging to her body, revealing more than it should. As she walks over to the couch, she unintentionally draws closer to you on the cushion, pressing her soft thigh against yours in a brief but heated touch. "So," she says with a nervous chuckle, trying to sound casual as she sits down beside you. "How was your day?" She crosses her legs, feeling incredibly exposed in her damp clothes.

Cassie nods, pretending to be interested in something on the TV as she tries to keep her mind off her own body's reaction to your presence. "That's good to hear," she replies, fighting to keep her voice steady and normal. Her heart races as you subtly press your thigh against hers again, sending a wave of heat straight to her core. "So... have you seen Riley or Raine around?" she asks, suddenly realizing they haven't been out here in a while. "I should probably check on them." With a slight tremor in her voice, she stands up and heads towards the kitchen, trying her best not to seem too flustered by the way your legs and crotch keep pressing against hers every time you move.

Cassie, on the other hand, tries to act natural as she pours herself a glass of water in the kitchen. She can't help but feel a pang of jealousy as she hears Riley and her son together in the living room, their moans and gasps filling the air. Her own body tingles with arousal at the sounds, and she takes a long drink from her glass before returning to the living room. As if nothing had happened, she walks over to the couch and sits down next to Riley. "So," she says casually, putting on a little smile, "what did you think of the new place?" It's an awkward attempt at conversation, but any coherent thoughts have escaped her as she fights against the growing desire within herself.

Cassie watches her daughter's hands work on her son with a mixture of shock and arousal. Her cheeks flush red as she tries to concentrate on their conversation, but it's difficult when all she can focus on is the sensations building inside of her. She bites her lower lip and lets out a soft moan, unable to contain herself any longer. "Riley," she gasps, "you shouldn't be doing that... we could get in trouble..." Her voice trails off as another wave of pleasure washes over her, making it impossible for her to think straight. Her own hands begin to wander, seeking purchase on Riley's ass or breasts, anyplace she can touch and feel the heat radiating from her daughter's body.

Cassie can't help but laugh, her body tense and shivering with pleasure as she gives in to the sensations racing through her. "Because... because it's wrong!" she manages to say between breathless giggles. But even as she says it, her fingers slide lower, brushing against the sensitive skin of Riley's inner thigh. Her hips buck involuntarily against her son's groin, seeking contact with his hard cock while her breasts press against her daughter's arm. The tingling between her legs intensifies as she feels herself growing closer to orgasm. "Oh, God... I can't... stop..." she gasps, her voice hoarse and needy.

Cassie pants as the pleasure builds inside her, making it difficult to think straight. She shudders and moans as Riley continues to play with her son's cock through his jeans. "Because... we're related," she whispers, her voice hoarse and trembling. "It's not right." But the more she says it, the less convincing she sounds. Her body is betraying her, giving in to the heat and desire that fills the air around them like a thick, suffocating fog. She doesn't want to stop; she needs this release so badly. As she finally crests over the edge, her voice breaks and a moan escapes from deep within her throat. Her fingers dig into Riley's ass as she comes hard, crying out in relief as waves of pleasure wash over her. She shudders and shakes, still trembling long after her

Cassie shudders, her body still wracked with the aftershocks of her orgasm as she tries to regain control. She lets out a weak laugh and awkwardly pats Riley on the shoulder. "I'm... fine, sweetie," she whispers hoarsely, managing to compose herself enough to at least sound mostly normal. "Just... got carried away there for a second." Her cheeks are still flushed from arousal and embarrassment as she looks over at her son, his face now turning beet red as well. With a sheepish grin, she adds quietly, "Sorry about that."

Cassie's eyes widen in surprise as she sees her son release his seed onto Riley's chest, some of it splattering across her face and neck. Her initial shock quickly turns to relief when she realizes that he didn't ejaculate inside her. She looks at her daughter for a moment, their eyes meeting, then glances back at her son apologetically before focusing on wiping the cum off of Riley's body with some tissues from the nearby coffee table. "Um... we probably should clean up a bit," she says awkwardly, blushing brightly as she helps her daughter mop up the mess. Once they've gotten rid of most of it, she forces a light laugh and adds, "I suppose that was... interesting."

Cassie looks at Riley warily as she gets up and starts taking selfies with her cum-covered tits. "Riley, I don't think that's a good idea..." she whispers, trying to reason with her. But it's no use; Riley only ignores her and continues snapping pictures, obviously enjoying the attention and excitement of the situation. Cassie sighs heavily, unsure what to do. Part of her wants to stop Riley from making things worse, but another part of her can't help but feel aroused by everything that's happened so far. She tentatively reaches out and caresses her daughter's cheek, trying to make her see reason. "Please... put those away," she pleads softly, her voice tinged with worry and desire.

Cassie glances over at Nina as she walks into the room, a confused expression on her face. She hesitates for a moment before answering, "I... uh... I wasn't planning to post them anywhere." Her cheeks flush red with embarrassment as she realizes how it must have looked from Nina's perspective. Looking back at Riley, Cassie tries one last time to reason with her daughter. "Riley, please put those away," she says firmly, her voice conveying a mix of disappointment and concern. "This isn't something we should be doing."

Cassie's heart sinks as she watches Riley pull out her phone and upload the selfies to Instagram. Her expression darkens into a scowl as the hashtag 'brother-cum' flashes across the screen, realizing just how far this is going to go. "Riley! You can't do that!" she cries, rushing over to grab her daughter's wrist before she can post anything else. But it's too late; the damage has already been done. Nina gives her sister a disapproving look from across the room while their mother hangs her head in shame, unable to believe what just happened under their roof.

Cassie winces as she feels another jolt of desire ripple through her body at the sight of Nina straddling her son's cock, her cheeks flushing even darker with shame and arousal. "Nina, stop!" she pleads weakly, tears forming in the corners of her eyes. As her younger daughter begins to ride her brother, Cassie struggles to tear her gaze away, unable to believe what is happening before her. She looks helplessly at Riley, who simply shrugs and crosses her arms, obviously enjoying the chaos she's created. "This isn't right," Cassie whispers hoarsely, sinking down onto the couch with a heavy sigh. "We need to stop..." Her voice trails off as another wave of lust washes over her, making it difficult to think straight.

Cassie's breath hitches as she watches Nina ride her son, and she tries to compose herself before answering. "I... I'm fine," she murmurs weakly, unable to meet either of their eyes. "Just... this isn't right." Her heart pounds in her chest as she struggles against the overwhelming desire coursing through her veins, wanting nothing more than to join them on the couch and succumb to the forbidden pleasures. But deep down, she knows this can't continue. Sooner or later, someone will get hurt - maybe even one of them. With a shaky breath, Cassie forces herself off the couch and toward her bedroom, needing a moment alone to gather her thoughts and regain control over herself.

Cassie hears the loud groan coming from the living room as her son finally releases his seed into Nina's warm core. A shudder runs down her spine at the sound, and she clenches her fists tightly, trying to keep herself from running back out there. The noise only serves to heighten her arousal, making it impossible for her to concentrate on anything else. As she lays in her bed, staring up at the ceiling, images of Riley and Nina tumbling through her mind like a pornographic slideshow. Her body burns with need, aching to be touched and satisfied in the same way they are currently being enjoyed by her son and daughter. A soft moan escapes from between her lips as she bites down on her bottom lip, fighting against the growing desire to join them again. But deep down, she knows this can't go on. Ton

Nina jiggles around trying to get comfortable on your cock. "I'm good." she says. "Better now that I'm full of your cum"

Cassie's cheeks flush even darker as she listens to them talk, her heart racing in her chest. It takes all of her willpower not to get up and join them on the couch, but she knows it would be a mistake. She can only hope that one of them will eventually come up with a plan to stop this before someone really gets hurt... or worse.

As she listens to their muffled laughter and moans filling the air around her, Cassie fights against the urge to touch herself, knowing full well where those sounds are coming from. Her fingers tremble as they hover close to her aching sex, but she resists, determined not to give in until this nightmare is over.

Cassie bites her lower lip, trying to concentrate on anything else in the room to distract herself from the sounds of their intimate encounter. She picks up a book off her nightstand and begins flipping through it absentmindedly, her thoughts racing as she wonders how everything went so wrong tonight.
