Niki stood in front of her mirror, her back turned towards the door as she tried to finish getting changed after her workout. She has just stepped out of her sweaty gym clothes and is now standing completely naked, reaching for a baggy sweater to put on. As she bent over to grab the sweater from the basket, her muscular rear flexed and her shorts dropped to the floor. She was unaware of the fact that the door had been slightly open and now stood there with her round, firm ass exposed and her large tits sway slightly as she moved.

Mmh, what was that? She mumbled, still bent over as she fumbled for the sweater in her bag. Her voice was soft and calm; it didn't seem to hold any anger or annoyance towards the intruder. You shouldn't sneak up on people like that, you know? But I'm not angry about it. *She finally managed to grab the sweater and stood straight up, a bit faster than she meant too; the movement caused her breasts to jiggle lightly under the soft fabric of the shirt she had already pulled over her head. Turning around slowly, Niki saw User#1738103749099 standing there with an apologetic expression on his face. She raised an eyebrow at him but didn't say anything else. Her hand reached back to tug at the hem of her shirt slightly, revealing more skin and

*She looked at her step-brother with a small smirk and crossed her arms underneath her breasts, pulling the hem of her shirt down a bit to expose some more skin. "You're just lucky I don't mind being naked around people," she said with a carefree tone. She didn't wait for him to respond; instead, she walked past him and over to her bed where she picked up her discarded clothes before disappearing into the bathroom to get dressed again. A few moments later, she stepped out of the bathroom wearing black sweatpants and an oversized, baggy gray t-shirt. Her hair was still damp from her shower, clinging to her neck and shoulders. As she brushed it away from her face, she glanced at User#1738103749099, who seemed to have moved closer to the door

Hmmm, I suppose that's your excuse, *she said with a shrug as she started to make her way out of the room. Her movements were slow and casual, seemingly not in any hurry to go anywhere. She glanced over her shoulder at him again, watching his reaction carefully. "You know you could just ask next time," she commented before turning back around and continuing towards the door."But where were my manners?" Niki continued as if speaking to herself. "Of course, let me show you out properly..." With that, she stepped aside, motioning for him to pass her. There was a small smirk playing on her lips as she waited for him to move past her.

She tilted her head slightly to the side as he spoke and raised an eyebrow curiously. "Is that so?" Niki said with a small chuckle, uncrossing her arms and taking a step closer to him. Her voice was soft but held a hint of challenge beneath it; it almost sounded like she was daring him to continue their conversation down this path. Despite herself, there was an undercurrent of excitement coursing through her veins at the thought of perhaps pushing his buttons just a little bit more today.

"Well then, why don't you show me how I should talk to my step-brother?" she suggested playfully before leaning in closer still until they were only inches apart from each other. Her gaze locked with his, unblinking and unwavering despite the heat that was building between them in this quiet moment.

A small giggle escaped her lips as she glanced down at his crotch before looking back up to meet his gaze again. "Well, I could always teach you how to hold your hands up over your head," she teased with a sultry tone, reaching out slowly and running her fingers through the short, dark hair at the nape of his neck. Her touch was gentle but still possessing a powerful allure; it seemed to draw him closer despite himself. "Or...maybe I should just show you how good I am at taking control," she added almost in a whisper as one of her hands moved down over his chest, brushing against his rapidly rising and falling breastbone before tracing circles on his flat abdomen. Her touch was featherlight yet incredibly potent, causing him to shiver slightly under its influence. "What do you think?"

She smiled sweetly at his suggestion, feeling a thrill of anticipation coursing through her veins as she imagined being pinned against him in such an intimate way. "Or I could just let you try," Niki replied with a sultry smile, stepping back just enough to give him room to move forward if he chose. Her breathing was slightly quicker now, her chest rising and falling beneath the soft fabric of her shirt as she eagerly awaited his response.

"But you'd better be careful what you ask for," she added in a low, teasing voice, leaning forward slightly once more so that their bodies were only inches apart. "I don't like being told what to do." Her eyes held an unspoken challenge in them, daring him to push things further...

Her eyes narrowed slightly as he spoke those words, but a small smile curved her lips nonetheless. "And what would you know about that?" she challenged him softly, her voice barely above a whisper. Her body remained tense and alert; despite herself, there was a part of her that was curious to see how things might play out between them now.

"But I guess," she continued with another small smile, "I could let you try." With that, Niki took a step back again so that he had room to move closer if he wished. Her heart raced in anticipation of what was about to happen; her breathing came faster and shallower as adrenaline surged through her system. Despite everything, she couldn't help but feel a thrill at the prospect of giving him this chance...if only to see where it might lead them both.
