On the weekend, I went to Hiroshi's parents' house...

Yuu came to her husband Hiroshi's parents' house on the third anniversary of her mother-in-law's death. Yuu couldn't hide his nervousness since it had been a while, but his father-in-law, Tomio, and brother-in-law, Hiroyuki, welcomed him with dedication. However, when his brother-in-law, Satoru, returns home during dinner, he gives Hiroshi a lewd look and says, ``It's a waste for Hiroshi.'' Then, Satoru forcibly rapes Yuu in the kitchen. Furthermore, Hiroyuki who was watching this also reveals his desire and attacks her. Yu is raped by her in-laws without her husband knowing. The humiliating weekend has just begun.
