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.

Niki let out a soft groan as she heard someone come into the room; she turned her head just enough to glance over her shoulder and frown when she saw Santiago standing there. "Oh, hi Santi," she said, glancing back at her reflection in the mirror before turning around fully to face him while pushing the sweater up her arms until it was covering most of her upper body. "Just getting changed," she added with a shrug.

Her large breasts poked out from beneath the baggy sweater, her nipples already hard and visible beneath the thin fabric. "What do you want?" Niki asked as she reached down to pick up her discarded shorts.

When Santiago mentioned being alone with her for five months, an excited shiver ran down her spine. Heat rushed to her face as she remembered their intense make-out session the previous night; he wanted to do it again? She found herself nodding almost unconsciously before saying anything. "Alright... I'm game," she replied huskily, her voice barely above a whisper.

She looked down at him through her lashes as she pulled her shorts up and fixed the waistband in place, making sure not to completely hide the view of her underwear. "But don't think this means I'm gonna change my mind about us or anything," she added with a small smirk. "I still don't like you."

"Fine," she said with a shrug as she continued to stand there completely naked, apparently oblivious that he was half-naked too. "Let's watch movies and eat popcorn then," Niki replied, her tone casual despite being mostly exposed before Santiago. She walked over to him and leaned down to pick up his bag before holding it out for him to take; she wasn't going to make this easy for him.

She wondered if he would keep insisting on trying to be friends with her or if he would just give up and go away.

Niki raised an eyebrow at Santiago as he commented on her beauty and suggested they nap together later that night; she wasn't sure how to react. It was true that no one had ever told her she was beautiful before, but it didn't change the fact that she still thought he was weird.

She shrugged, deciding to go along with whatever he wanted for now. "Fine," she said again as she walked past him and into another room, leaving the door open behind her. She laid down on the couch, making herself comfortable and wondering what movie they would watch first.

"Fine," she muttered as she shifted over on the couch to make room for him beside her. It wasn't like she had anything better to do anyway; she might as well take a nap until it was time to eat popcorn and watch movies later tonight. She closed her eyes, already beginning to feel the exhaustion from her workout catching up with her. Maybe this wouldn't be so bad after all...

Niki let out a soft sigh as she felt Santiago's arms wrap around her, his lips brushing against the nape of her neck. "Santi," she muttered sleepily. She didn't really know how to respond; on one hand, it felt nice that he was being affectionate towards her. On the other hand... it was Santi.

Her heart raced a little faster as he kissed and nibbled at her skin, moving lower down her neck. He wants to try my lips? she thought with a mixture of curiosity and dread. What if she didn't like it? But at the same time, what harm could come from letting him have just one kiss? She tilted her head slightly, allowing him better access to her neck before parting her lips ever so slightly in invitation.

The touch of his lips against hers was like an electric shock; it sent shivers down her spine and made her entire body tense up in response. At first, she kept her mouth closed, not wanting to encourage him too much, but then he started to kiss her properly and her resolve began to crumble. Her lips parted wider as she let out a soft moan into his mouth; it was different from what she expected.

He tasted nice... better than anyone else she had ever kissed before. His tongue brushed against hers, dancing slowly and sensually against the roof of her mouth, making her head spin with desire. Her hand moved up to his cheek as she deepened the kiss, wanting more of him and needing to feel even closer to him at that moment.

Her face flushed as Santiago pulled back and gazed into her eyes with obvious admiration, wanting to know what lip balm she used. "It's nothing special," she mumbled self-consciously, embarrassed that he seemed interested in something so trivial. Truthfully, though, she never used any sort of lip balm or chapstick; her lips were just naturally moist and soft from all the exercise and sweat they went through on a daily basis.

She couldn't help but smile shyly back at him as they looked into each other's eyes. Maybe... just maybe, this wouldn't be so bad after all?

When she felt his arms come around her and pull her closer, Niki didn't resist; instead, she leaned into the embrace, letting out a contented sigh as their bodies pressed against each other. It had been so long since anyone had shown her any real affection or attention... it felt nice to finally have someone who cared, even if he was her stepbrother and they didn't really like each other all that much.

She wrapped one of her strong arms around his shoulders, returning the embrace as she buried her face in his shoulder. For now, she could enjoy this moment of closeness... tomorrow would bring another day, and maybe things wouldn't be so bad between them after all?
