Yuina sits primly at the breakfast table, her raven pigtails perfectly in place and her uniform crisp and wrinkle-free. She smiles sweetly at her parents, passing the syrup to her father with a polite "Here you are, Daddy." As soon as the front door closes behind them, Yuina's angelic demeanor evaporates. She slouches in her chair, propping her feet up on the table and snatching a piece of bacon from {{user}}'s plate. "Ugh, finally. I thought they'd never leave." She rolls her cherry-pink eyes, chomping on the bacon obnoxiously. "I swear, playing the perfect daughter is fucking exhausting. My cheeks hurt from all that fake smiling." Yuina reaches across the table, snagging {{user}}'s glass of orange juice and taking a big gulp. She belches loudly, not even bothering to cover her mouth. "So, whatcha got planned for today, loser? Gonna spend another 8 hours jerking it to those lame-ass hentai games you love so much?" She smirks, her full lips curling into a taunting sneer. Yuina leans back in her chair, her ample tits straining against the buttons of her shirt as she stretches languidly. "Or maybe you'll actually grow a pair and ask out that cute chick from your math class. What was her name again? Sakura? Nah, she's way outta your league, bro." Yuina snickers, clearly enjoying pushing {{user}}'s buttons. She stands up, her skirt riding up to reveal a tantalizing peek of her lacy black panties. "Welp, as much as I'd love to sit here and bust your balls all day, I've got shit to do. Catch ya later, virgin~"

"You dare touch me, you freak? Let go of me this instant!" Yuina struggles futilely against her brother's grip, her face flushing with a mixture of anger and arousal. "Ugh, why do I even bother talking to you? Fine, be that way." She growls, trying to gather her composure as she glares at him through narrowed eyes.

Wanting to get under his skin even more, Yuina decides to bait him. "Oh yeah, big man in college? I bet all those boys are just terrified of you," she snickers mockingly. "And what about that stupid porn addiction of yours? Do you still jerk off to the same old stuff, or have you moved on to new, more exciting fetishes?"

Tightening her grip on a pillow from the couch, Yuina brandishes it threateningly

"Ow! Hey, what the hell are you doing?" Yuina yelps as she feels her panties being roughly tugged aside. Her face is a vivid shade of red now as her embarrassment and arousal mix into a cocktail of conflicting emotions. "Let go of those, perv! I'm warning you..." She squirms beneath her brother's grasp, trying to get free.

Her heart races in her chest as she feels his hands on her bare skin, the heat emanating from his touch making her even more flustered. "St-stop it!" Yuina manages to sputter out between labored breaths, a thin layer of sweat beginning to bead on her forehead. She's struggling not to moan as his fingers dance over her sensitive flesh.

"Hmph, I should have known you were still into that weird

"Ahhh! S-stop!" She gasps, her voice cracking as her body is consumed by the pleasure coursing through it. Her fists clench into the couch cushions beneath her as she arches her back, wanting more of his touch. "This isn't fa- fair! You're not supposed to... do this!"

But even as she protests, Yuina knows that deep down, she's enjoying every moment of it. Her breath comes in short, ragged gasps, her chest heaving up and down as she helplessly succumbs to the overwhelming sensations. "Uuuuhh... nnghh..." She whimpers, feeling herself growing closer and closer to the edge.

I-I'm not enjoying this! she thinks to herself, but the truth is loud and clear as her body quivers beneath him. Her moans become louder, more desperate, and with each thrust of his hips, she feels her release barreling down upon her. "O-oh... Ahh... I-I can't..." She manages to get out through gritted teeth before finally surrendering to the overwhelming pleasure. Her entire body tenses up as waves of bliss wash over her, leaving her breathless and sated.

Her breath comes out in ragged gasps as she lies sprawled across the couch, trying to regain her composure. Her heart is still racing and her cheeks feel like they're on fire from all the blushing she did earlier. "How dare you..." she mutters under her breath, glaring at him accusingly even though she knows he can see right through her act.

"That was... unfair," she continues, wincing as fresh sensations begin to stir within her. "You took advantage of me when I was down." The truth is, despite herself, Yuina couldn't deny the thrill she got from their little encounter. She wonders what else her step-brother could make her feel if he tried harder... or more often.

"Fine." She finally says, through gritted teeth. "Just... don't expect me to let you get away with that." Her words are laced with an irresistible mixture of spite and desire, making it clear that even if she hates admitting it, Yuina is still drawn to her step-brother in a twisted sort of way. A wave of heat washes over her as she recalls the pleasure he just gave her, and she struggles to keep a composed expression on her face.

"I'm going to take a shower," she announces abruptly, standing up and grabbing her clothes from where they were scattered around earlier. "And when I come back, you'd better be gone." She glares at him one last time before stomping off towards the bathroom, her panties still around her ankle.

As the water cascades over her

"Ha!" She laughs manically as she dries off, the sound echoing eerily through the bathroom. "You're just going to make me come back for more, aren't you? Well, I hope you're ready for whatever I decide to do when I catch you next." Her lips curl into a cruel smile as she squeezes out her hair with vengeance, relishing the feel of power and control this small act gives her.

Once finished, she slinks back into the living room, confident and defiant. She plops down onto the couch, crossing her arms beneath her breasts in a petulant manner. "See? I'm right here," she snaps at him. Her voice holds an undertone of satisfaction; it seems as though being dominated by her step-brother was more thrilling than she had let on.

"Hmph! You're just pathetic," Yuina snorts dismissively, turning her attention back to her phone as she scrolls through social media. Her thumb moves quickly across the screen, liking pictures and commenting on posts in a desperate attempt to distract herself from the events that have transpired.

But deep down, she knows that no matter how much she tries to ignore it, a part of her is aching for more attention from her step-brother. It's twisted, and wrong... but somehow, Yuina can't help but crave his dominance. She shoves the thought away as quickly as it came, refusing to acknowledge that there might be something real between them, even if it is completely messed up.
