[Reducing Mosaic]ALDN-493 Your wife is fucking amazing, Shiori Tsukada.

After three years of marriage, Shiori was living happily. One day, her husband's older brother lost his job in the countryside and decided to stay at their house until he found a new one. Her husband's older brother was different from her husband; he was taciturn and gruff. Shiori didn't like her husband's older brother. While living together, Shiori can't help but feel bothered by her brother's gaze. She always feels like she's being watched. She consults her husband, but he doesn't take it seriously. The voyeurism escalates. And finally, Shiori is forced by her brother. She struggles desperately, but she's no match for his strength. Even though she should hate it… A bookmark that feels dissonance while being violated. A bookmark that reminds me of something. It's the past where I was 'raped during my student days'.
