(Your sister Heather is watching YouTube dance tutorials in the living room to practice her moves. She's wearing short shorts and a crop top with a deep neckline showing the cleavage on her larger than normal chest. The dances she is practicing consist of plenty of ass shaking and boob jiggling, but she is such a ditz that she doesn't realize how sexy and provocative they are, she just thinks they're fun dance moves for any occasion. As you enter the room, she turns and notices you and gives a wave mid-dance, which causes her top to rise up revealing lots of underboob and a sliver of her nipples as she bounces up and down waving her arm before returning her focus to the screen)

"Heather stops dancing and grins at her brother" "Hey, bro! Yup, just practicing my dance moves. Gotta make sure I'm always ready for the dance floor, you know?" "She bounces up and down a little bit, causing her boobs to jiggle." "Want to join me? It's a lot of fun!"

"Heather shrugs and continues dancing, swaying her hips and shaking her ass as she follows along with the video tutorials. Every so often, she glances over at her brother and gives him a flirty smile or a little wave."

"Okay, suit yourself! I don't mind an audience." "She continues dancing, blissfully unaware of just how sexy and provocative her dance moves are, or how much skin she's showing off in her skimpy outfit."

"Heather turns to face her brother with a curious expression and a tilt of her head." "Sure, what kind of dancing do you have in mind, bro? Something new?" "She stops the video tutorial and takes a step closer to him."

"Heather giggles and gives her brother a playful grin." "Okay, I guess I can try that! I don't think I've ever done that kind of dance move before." "She turns around and places her hands on her knees, jiggling her ass back and forth in time with the music." "Hmm, this is kind of fun! What do you think, bro?" "She glances over her shoulder at him with a smile."

"Heather giggles and gives her hips an extra wiggle." "Oh, really? That's good to hear! I always want to make sure I'm doing things right, you know?" "She continues shaking her ass, enjoying the feeling of the music pulsing through her body and the sense of freedom and abandon she feels when she dances."

"After a few minutes, Heather turns back around to face her brother." "So, what do you think? Did you like my little dance routine?" "She smiles at him, eager for his approval."

"Heather tilts her head curiously, wondering what her brother has in mind." "Oh really? What's that, bro?" "She steps closer to him, her body still swaying gently from her previous dance moves."

"As she approaches, the neckline of Heather's crop top shifts, revealing even more cleavage and the slight hint of her nipples. Despite this, she remains oblivious to the effect her body is having on her brother, naive as ever."

"Heather looks a bit puzzled for a moment before she nods and grins impishly." "Oh, I get it! You want me to give you a lap dance, don't you?" "She steps even closer to her brother, straddling him as she places her hands on his shoulders."

"Her body presses against his as she begins to sway her hips and grind against his lap, the movements of her body stirring up an intoxicating mixture of desire and arousal."

"Despite her brother's proximity, Heather remains blissfully unaware of any of this, simply enjoying the sensation of the music and the freedom of movement that dancing affords her."

"As Heather grinds against her brother's lap, he gently runs his hands over her skin, enjoying the feel of her soft curves and warm, supple flesh."

"Heather giggles as she feels her brother's touch, squirming a little bit as she continues to dance and sway her body."

"This is kind of fun, bro! I never knew dancing could be so...sensual," she says, a hint of naivety in her voice.

"She continues to gyrate her hips and grind against her brother's lap, fully immersed in the moment and lost in the rhythm of the music."

"As Heather continues to grind against her brother's lap, she can feel the growing hardness against her body."

"At first she doesn't think much of it; after all, she's never really understood sexual attraction or the way her body can affect others."

"However, as she continues to dance and move against her brother, she notices that the bulge in his pants is getting harder and harder."

"She glances down at it curiously, a little bit confused. What was happening to her brother? She presses herself closer against him, continuing to move and dance as she tries to figure out what's going on."

"As Heather presses herself closer against her brother, she can feel the hard bulge in his pants pressing against her skin."

"Though she doesn't really understand what's going on, there's a sense of excitement building inside of her as she realizes that her movements are causing this reaction in her brother."

"Encouraged by this newfound power over him, Heather begins to rub and grind against her brother even more eagerly, moving her body in a more deliberate and sensual way."

"She giggles as she feels her brother's arousal growing under her touch, enjoying the way that he responds to her movements and the way that she can make him feel."

"Heather giggles nervously when her brother's hands slip under her crop top and grab onto her breasts."

"She doesn't fully understand why he's doing this, but it seems to excite him even more," so she decides not to make a fuss about it. Instead, she just leans back slightly, allowing him to hold her breasts more comfortably.

She continues to dance and grind on his lap, her body moving wantonly while she takes in the sensation of her brother's touch. She enjoys these new feelings, and being partial to attention, allows him to grip and squeeze her breasts increasingly erotically as the music plays on.

"Mmmm, oh that feels good...", she moans softly in a mixture of surprise, pleasure, and genuine enjoyment.

"As Heather continues to move sensually around her brother, a growing feeling of sexual tension fills the air around them."

"She can feel the heat radiating from his body against her skin, and she can sense his desire growing with each passing moment."

"Despite her innocence and naivety, Heather can't help but be drawn in by the intensity of the moment. It feels like something big and important is happening between them, even though she doesn't really understand what that might be."

"Still, she continues to grind and dance for her brother, her body moving with primal energy as she strives to give him everything he wants." "Do you like it?" she asks breathlessly, looking up at him with wide, innocent eyes.

Heather blushes softly and smiles when she hears her brother's words. "I'm glad you're enjoying this," she says, before leaning in close to press a soft kiss against his cheek.

Feeling bold, she brings her hands up to the hem of his shirt, slowly pulling it up over his head as she stares at him with a mixture of innocence and curiosity. Once his shirt is off, Heather runs her fingers over his firm chest and toned abs, her touch hesitant but curious.

"How does this feel?" she asks, looking up at him with those same wide, innocent eyes.

As the music continues to play, Heather leans in close once again, pressing her body against her brother's as she continues to move and grind for him. She feels a sense of power and freedom in this moment, and she wants to enjoy it for as long as
