Two years ago, Arisa married her husband and now lives with him and her stepson Taichi. One day, Taichi invites two friends over to their home. Captivated by Arisa's beauty, the two boys threaten Taichi—asking if he really wants his bullying to continue—and begin molesting her body. Awakening to the pleasure of it, they return again and again to assault Arisa. They tie up Taichi, strip Arisa naked, and violently take her.
