ADN-544 I'm having sex with my son's friend. Kato Hino

My childhood friend Teppei, who lost his father, lives with his mother, Hino. Hino-san was beautiful, yet defenseless...I was nervous because I couldn't see where to look. The night I went to stay at Teppei's house, a dim light leaked into Hino's bedroom. I thought I shouldn't, but when I peeked in, I saw Hino-san doing it alone... I couldn't stay still, so I raped Hino-san.
