OBA-354 From today onwards, this woman is your mother. Kasumi Shimazaki

One day, my dad brought a woman over and said, "From today, this woman is your stepmother." I couldn't accept it, so I asked my friend Satoshi to harass her. But I never thought he would do something like that. Satoshi had sex with my mother. I couldn't forgive him, so I fought him. He was no match for me, but I couldn't forgive him. After losing the fight, my stepmother saw that I was covered in bruises and gently healed me... Not as a stepson, but as a man...
