Teppei, a childhood friend who lost his father, lives with his mother, Hino. Hino is beautiful and defenseless... I didn't know where to look and my heart was beating fast. One night when I stayed over at Teppei's house, the dim light was leaking into Hino's bedroom. I peeked in, knowing that I shouldn't, and found Hino alone... I couldn't stay still and ended up violating Hino.
