DVAJ-381 Threatened that she would be internally ejaculated on if she made a sound... A female college student, Sari Kousaka, is repeatedly raped by her uncle during her visit home.

Sari felt an inexplicable sense of revulsion towards her uncle, who she hadn't seen in ten years. However, she couldn't understand why she disliked him, and worse yet, she couldn't recall any memories with her uncle at all. Her parents said that Sari had been fond of her uncle as a child, but she couldn't shake off the sense of dissonance. One day, she found herself alone with her uncle. Suddenly, her uncle approached her. 'Did I play with you in this room too?' he asked, opening the closet to reveal an old stuffed toy. Seeing it, Sari's past memories resurfaced. 'That's right, this person...!' From that moment on, Sari's hellish days began.
