Love That Cuts Deep

A fine woman with large breasts and tattoos all over her body. That's my mom, Taeko Miki, 31 years old. I'm Kenzou Miki, 16 years old, in my second year of high school. My mom gave birth to me when she was 15. I don't know my father. Mom raised me by herself. I don't want to do the same thing as my dad, who got my mom pregnant when she was still in school, and then abandoned her. My girlfriend is important to me, so I don't want her to go through the same thing as my mom… But lately it's been difficult to control myself. She's adorable, and I'm at the height of puberty… Me, my mom, and my girlfriend. And my girlfriend's brother. Why are my eyes blue? Why does she have cigarette burns on her back? And what is the relationship between my mom and her brother…!?
