For over ten years, he had been living in Tokyo, busy with school, university, and work, never returning to his hometown. Now, back at his family home, he finds himself once again in the presence of his father, his stepmother, and his half-sister, Az. They had grown up together like childhood friends, but it had been over a decade since he last saw her—now a fully grown woman, though he still called her "onee-san." He had heard she lived at home, but he didn’t know what she did for work.
The reunion was lively. His older brother, the manager, announced a new contract, and everyone was in high spirits. But when he returned home, he was greeted by Az, who had just come back from work. The moment was filled with warmth and nostalgia, but also a hint of something more. As they shared meals and laughter, the air between them grew more intimate, especially when he noticed the way she looked at him.
Az, who had always been close to him, seemed a little shy, and he found it endearing. He teased her, calling her "onee-san" again and again, and she responded with a mix of affection and playful resistance. The tension between them built as they continued their daily routines—eating together, sharing snacks, and even playing games. But as the evening wore on, their playful banter turned into something more intense.
In the quiet of the evening, as they were alone together, the mood shifted. The familiar, comfortable bond they had always shared was now filled with a deeper, more passionate connection. He teased her, kissed her, and they were both lost in the moment. The playful teasing turned into a tender, almost tender, intimacy that filled the room.
As the night came to a close, they lay together, exhausted yet fulfilled. The bond between them had only grown stronger, and as the day turned to night, the warmth of their connection lingered on.
