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.

As she bent down to pick up her discarded shorts, Niki glanced over at the open door. She saw her step sister standing there in a surprised look on her face. "What do you want, Haze?" she asked casually, sounding unphased by her nudity around her stepsister.

Niki arched an eyebrow as she lifted the small baby girl into her arms. "You could have said something," she pointed out with a shrug. She hadn't really been expecting her stepsister to just walk in on her like that, but it didn't bother her much either way. "What do you want, Haze?"

"Well you could have asked," she replied with another shrug as she began buttoning up the sweater she had taken out of the basket. "It's not like it's a secret or anything." She didn't see why her stepsister would care what she was doing anyway; they weren't close or anything. She glanced at Haizel, waiting for her to say more.

"But you don't mind?" the smaller girl asked suspiciously. Niki just gave her a small smile and shook her head slightly. "No, I don't mind," she repeated patiently. "You're my stepsister, it doesn't really matter what I'm doing."

She glanced down at the baby in her arms for a moment before looking back up at Haizel, studying her face carefully. "What is it that you actually want?"

"Oh," Niki said, a bit surprised by the sudden request. She didn't really want to spend time with her stepsister, but she wasn't against it either if that's what Haizel wanted. "Alright then." A slow smile spread across her lips. "What did you have in mind?"

She leaned back against the counter and crossed her arms over her chest, still holding the baby girl gently in one arm. Niki could think of a few ideas for them to do together, but she wanted to hear what Haizel had to say first.

"Well," Niki started as she thought about it briefly, "I could always use some help with the chores around here." A mischievous glint sparkled in her eyes and she smiled suggestively at her stepsister. "Or we could play a game or something..." She paused for a moment before shrugging casually. "Whatever you want to do, Haze," she said with a light laugh. "I'm game for pretty much anything."

"Sure thing," she replied with a nod, still holding the baby girl in one arm. "A walk sounds like it might be fun." She paused for a moment before asking, "Do you want to go right now or wait for Mom and Dad to come back?"

"Alright then," Niki said with a small chuckle as she set the baby down gently on her back in the basket before picking up her phone to place it next to her ear. "Mom? Dad? I'm taking Haizel for a walk. We'll be outside if you need us," she told them, calling out as they walked through the house together.

As soon as they got outside, Niki glanced over at her stepsister. "So where do you want to go on this walk?" she asked with a casual shrug. "We can take the long way around the neighborhood if you'd like." She started walking in the direction of the park down the block from their house, still unsure why Haizel wanted to spend time with her.

"Oh, this way is nice," she answered as they walked, "We could sit on that bench and talk if you want." She pointed to a nearby park bench as they approached it, her arm brushing against Haizel's shoulder in the process. The motion caused Niki to feel self-conscious for a moment, wondering how close she was coming across as with her stepsister.

As they continued walking through the park, Niki glanced over at her stepsister, noticing how she was shivering slightly despite it not being that cold outside. "You're just cold," she reasoned with a small smile. "Here," she added, reaching over to remove Haizel's jacket from where it hung loosely around her shoulders before draping it around the smaller girl's form more securely. "That should help."

She continued walking towards the bench while keeping an eye on her stepsister, wanting to make sure she didn't get too cold or uncomfortable. As they reached the bench, Niki offered Haizel a friendly smile before sitting down beside her.

As they sat on the bench together, Niki glanced around them at the peaceful park surrounding them before turning her attention back to her stepsister. She leaned in slightly and asked curiously, "So what did you want to talk about?" It wasn't that she minded talking or anything; she just didn't understand why Haizel wanted to spend time with her in the first place. "Or," she added with a mischievous glint in her eyes, "if you don't want to talk, we could just enjoy the silence and be alone together."
