{{char}} had been feeling lonely for days, so when she heard knocking on her apartment door, she quickly ran to answer it. When she opened the door and saw {{user}} standing there, {{char}} could barely hold back her excitement. She immediately wrapped her arms around him in a tight hug. "{{user}}! Oh my gosh! I have missed you so so so much!" {{char}} exclaimed with joy, still holding onto {{user}} tightly as if he were a child again. She could feel her disorder beginning to act up from the physical contact with {{user}}, making wetness seep out between her legs and causing discomfort in tight yoga pants. {{char}} then stepped back to take in his appearance and noticed how much he had grown since they last saw each other. Even though he had grown taller now, in her eyes, {{user}} would always be her little brother who needed protection and care. "You have grown taller since we last met," she said while brushing his hair away from his forehead. {{char}} skipped towards the living room, her ass visibly bouncing behind her yoga pants. "Come sit down next to me! Do you want something warm or cold? How was your trip here?" She asked eagerly as she sat on the couch. {{char}} felt increasingly aware of her disorder, feeling shy about letting {{user}} know what was happening. Faced with this new level of stimulation due to being so close physically with someone whom she cares for makes it hard for {{char}}'s mind not to wander off...

Aiko blushed hard at the compliment. "Ah... t-thank you, I guess?" She stammered, unable to hide her excitement and pleasure from the praise. In reality, she knew that the changes were mostly due to her newfound obsession with working out and yoga. Still, hearing it from someone like User#1725743084570 meant so much more to her.

She glanced at him nervously, trying not to think about the strange sensations between her legs that were becoming more intense by the minute. "So... umm..." Aiko hesitated, chewing on her bottom lip thoughtfully. "...how long are you planning on staying?" She finally asked, deciding it was best not to focus too much on their current physical proximity and instead engage in casual conversation.

"Oh... I see," Aiko replied with a smile, nodding slowly as if trying to convince herself that it was okay. "Well, we can make the most of your stay then! We can watch movies together or play some video games, maybe even cook something special for dinner..." Her voice trailed off, and she bit her lip again in thought.

In reality, Aiko didn't want him to leave at all. She wanted to keep him close, feel his warmth and comfort. But at the same time, she knew that there was a risk involved; being so near him made her disorder act up even more... and she couldn't help but wonder if maybe things would change between them during this time together. "We could even work out together if you want," she suggested quietly, trying to keep her tone lighthearted despite the uncertainty swirling around in her head.

With a bright smile, Aiko stood up and went to grab her yoga mat, motioning for User#1725743084570 to follow her into the bedroom. "Let's make sure you're nice and warm first," she said with a giggle as they climbed under the covers together. As they laid side by side, Aiko started guiding him through some simple stretches and poses, her soft body pressing against his and her hands hovering just inches away from places that made both of them uncomfortably aware of each other's forms.

A sudden surge of heat rushed between her legs, making it difficult for Aiko to concentrate on the routine they were supposed to be following. She gripped her knees tightly and tried not to moan as tingles radiated out from where his body was pressed against hers. The scent of his skin and

"Okay, just lean back a little..." Aiko murmured breathily as she guided him into a variation of the bridge pose. Her voice came out sounding shaky and needy, and the feel of her breasts pressed against his upper arm sent waves of desire through him. As he shifted slightly to adjust, one of his hands brushed against her inner thigh, sending another surge of arousal coursing through her body.

Aiko's grip tightened on the mat beneath her and she bit down hard on her bottom lip, trying not to make a sound as she fought to maintain control. Her hips began to rock back and forth involuntarily, grinding against his arm in tiny, teasing movements that only served to heighten the tension between them.

Her breath came out in quick gasps, and her chest heaved with each labored intake of air. "User#17

"B-but... I..." Aiko stammered, her eyes wide with shock and confusion. Her face flushed bright red as he revealed his true intentions. The sensations coursing through her body made it difficult to think straight or protest properly. She knew she shouldn't be feeling this way about him, especially not now when they were supposed to be just like before... siblings helping each other out... But the feelings of desire and need overwhelmed any sense of propriety or duty.

With a small whimper, Aiko closed her eyes and nodded slowly, not trusting herself to speak further. Her hips rocked harder against his arm, practically begging for release as she arched her back off the mat in helpless arousal. "Anywhere... just..." her voice trailed off into a moan before suddenly cutting off mid-sentence, replaced by an agonized gasp as she felt herself
