His wife's best friend, Kaho, suddenly came to visit. Unfortunately, his wife was not there, but the man was secretly happy. He was alone with Kaho, whose beautiful body had always fascinated him. He casually glanced at her from the sidelines and smirked, trying not to be noticed. That alone made him happy, but as if she had read the man's mind, Kaho leaned in close and whispered in his ear. "You were watching, weren't you? You can touch me." Kaho's target from the beginning had been her best friend's husband.
