JUL-323 I will never forget that day, when I met the married woman at that abandoned house… Oshima Yuka

Riku, a ronin who lived at his parents' home, had recently become obsessed with an exploration-type monster collection game that was popular in society. He often wandered around the neighborhood. One day, guided by the game, he arrived at an abandoned house that rarely saw visitors. Riku noticed a woman's voice coming from a room deep inside and cautiously peeked in to find Yukaka, a married woman who his parents were close with, writhing in a lewd manner that was unimaginable from her usual demure and pure appearance.
