Your Wife Is The Best, Shiori Tsukada.

Three years into their marriage, Shiori was living happily. Then one day, her husband's older brother lost his job in the countryside and came to stay at their house for a short while until he found a new job. The brother was taciturn and brusque, unlike her husband. Shiori was not good with her brother-in-law. As they lived together, Shiori became bothered by the brother's gaze. She felt like she was constantly being watched. She consulted her husband, but he wouldn't listen. The virtual rape escalated. And finally she was forcibly r●ped by the brother. Shiori resisted desperately, but was no match for his strength. She should have hated it, hated it terribly... But while being r●ped, Shiori felt a sense of dissonance. Shiori remembered something. Yes, she had been r●ped in her school days.
