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 nods approvingly at your answer, her focus still fixed on the task at hand as she teases herself closer to climax. "Oh, that sounds interesting," she pants, moving a bit faster now. "Maybe we could do something like that together sometime." Her other hand slides between her legs and begins rubbing in rhythm with her fingers, thrusting into the air with each stroke. "Mmhmm... yeah, like this..." She moans louder as her body tenses, the orgasm finally washing over her. "Ahhh!" Her hips buck violently against the door and she lets out a long, satisfying groan before going still. After a moment, she opens the bathroom door with her foot and steps out into the hallway, looking more relaxed now that she's finished. "There you go," she smirks, brushing past you to head back to your

Cassie smiles reassuringly and gives you a quick hug, her breasts pressed against your arm as she wraps her free arm around you. "I'm feeling much better now," she purrs. "Thanks for being so understanding." She takes a step back, studying your face carefully. "You didn't look too bored out there, I hope?" A playful glint returns to her eye as she notices the way you take in her still-visible arousal beneath her bathrobe. Her smile turns mischievous. "Maybe later tonight we could find something more interesting for us both to do." She winks and saunters away, leaving you with a distinctly unmistakable bulge in your pants.

Cassie raises an eyebrow at your suggestion, intrigued by the idea. "Oh really?" she asks playfully, taking a step closer to you. "You know I'm not very good at those... But it could be fun to try together." Her breath is warm on your cheek as she leans in slightly. With her free hand, she reaches up and tucks a stray lock of hair behind your ear, the touch sending shivers down your spine. "Lead the way," she whispers, her voice low and seductive.

Cassie follows you into the living room, watching with curiosity as you gather some scraps of paper and other materials off the coffee table. Her eyes travel appreciatively over your body as you work; she can feel herself growing aroused all over again just by being near you. As you begin to show her how to fold and manipulate the paper into basic shapes, her mind drifts in and out of concentration, fixating instead on the way your muscles ripple under your skin and the scent of your cologne that hangs heavy in the air. It's becoming increasingly difficult for her to focus on aeromodeling...

Cassie nods, feigning interest in the aeromodeling plans as you begin to assemble everyone in the living room. Her heart races when she sees Nina and Riley glance meaningfully at her before looking away again, clearly aware that something is going on between the two of you. It's not long before Anne joins them too, her face a mix of amusement and curiosity as she watches Cassie struggle to pay attention to the task at hand. With everyone assembled, you start explaining your plans for the model, gesturing animatedly with your hands while glancing occasionally at Cassie for confirmation or assistance. She follows along, but her focus is mostly on the way your movements cause the fabric of your shirt to stretch tight across your chest and abs. Her mind wanders further as she imagines running her fingers over those defined muscles...

Cassie nods absently, her attention still firmly fixed on you as she listens to your plan. She tries not to be too obvious about it but finds herself frequently stealing glances at your lips, wishing they were closer to hers. The thought of touching those full, pouty things sends a shiver down her spine. As the others begin helping you set up the model and work on the electrical components, Cassie finds herself drifting closer to you once again. She leans against the nearby bookshelf, feeling awkwardly self-conscious about how close she's standing but unable to resist the pull. The heat between them is almost unbearable now...

Cassie's heart skips a beat as she looks at your exposed chest, her eyes trailing over the smooth, hairless skin and defined muscles before snapping back up to meet your gaze. "Y-you can take off your shirt if you like," she stammers, feeling her cheeks heat up. The air in the room seems suddenly thick with desire and tension as everyone nearby notices their exchange, their eyes darting between the two of you expectantly. Your mother takes a step closer, reaching out to brush a lock of hair away from your face. "But we should probably focus on getting this model done first," she whispers huskily, her breath fanning across your cheek. Her fingers lightly graze your jawline before pulling back, leaving a trail of warmth in their wake.

Cassie's cheeks flush deeper at your accusation, but she doesn't deny it. In fact, her gaze drifts back to your chest before meeting yours again. "Fine," she breathes, a mix of reluctance and desire in her voice. "We can take a quick break..."

She takes another step closer, wrapping her arms around you as their bodies press tightly together. Her soft breasts are flush against your bare chest now, and with a small moan, she arches into you, seeking more contact. The feel of her skin on yours sends waves of desire coursing through you both; it's clear that this "quick break" is going to be anything but quick.

As your hands move up to cup her bottom, squeezing gently, Cassie pulls back slightly to look into your eyes. Her lips part as she lets out a shaky breath and le

Cassie blushes deeply at your insistence, confused and aroused by your rejection despite the clear desire building between the two of you. She takes a step back, raising her hands in protest. "Fine, fine," she says, her voice shaking with emotion. "Let's focus on the airplane then."

Her heart races as she watches you begin working on the model again, unable to ignore the way your muscles ripple and flex under your skin every time you move. Her eyes drift lower, taking in the defined outline of your abs before traveling higher once more to meet your gaze. The tension between them is palpable, electric, but for now it seems they're going to have to find a way to contain it... or maybe even channel it into something more productive.

Cassie looks around for a moment before spotting the small tool on one of the bookshelves nearby. "Right here," she says, reaching up to grab it and handing it over to you. As their fingers brush against each other, an electric current seems to pass between them once again. Her breath catches in her throat as she watches you work on the model, admiring how focused and skilled you are at fixing things together with such precision. It's almost enough to distract her from the heat building within her every time she looks at your bare chest... almost.

Cassie smiles warmly at you as she takes the completed airplane model into her arms, marveling at how beautiful it is despite all of its rough edges and blemishes along the way. "Thank you," she whispers, genuinely grateful for your guidance. "I can't wait to see it fly."

Her eyes linger on your face a moment longer before she turns her attention back to the rest of the family. Nodding to Anne and Riley in acknowledgment, she clears her throat awkwardly, unsure how much more time they should spend together like this. "Well, I think we've all learned quite a bit today," she says with a small laugh. "Maybe another lesson next time?"

Cassie watches as you head toward the bathroom, feeling a pang of regret wash over her. There were so many more things she wanted to say, do... But

Her cheeks flush as she hears the bathroom door close, but Cassie manages to maintain her composure. She takes a deep breath and turns back to the group, forcing herself to focus on something other than the intoxicatingly erotic sight of you naked in front of her. "Well, shall we call it a night then?" she asks brightly, trying to pretend that nothing out of the ordinary has happened.

The others nod their agreement and begin to gather their things, preparing to head off to bed. As they file past Cassie on their way out, she catches Nina and Riley exchanging knowing glances again. The thought makes her blush even deeper but also fills her with a strange sense of camaraderie; whatever's happening between them all, it's clear that it runs deeper than just the surface-level flirtation they've been engaging in tonight.

With

Cassie busies herself by gathering some things up off the counter as you emerge from the bathroom wrapped in a towel. Her heart skips a beat at the sight of your toned physique, and she can feel her cheeks burning with embarrassment again when their eyes meet briefly. "Well," she says casually, trying to sound calm and collected. "That went by quickly, didn't it?" She turns back to the kitchen, intent on making some tea to help settle her nerves. "I should head up too. Goodnight, dear." Her voice wavers slightly as she forces herself not to look back at you while walking away.

Once safely in her bedroom, Cassie collapses onto the bed with a shaky sigh. This has been one of the most intense experiences of her life, and she's not sure what it all means for any of them. All she knows is
