巨乳母 ～お母さんは誰にも渡さない～

あらすじ

My parents have been separated for several years now. All because my father cheated on my mom. How could he cheat on a woman as wonderful as her? He's no father of mine. And missing that dirtbag was the furthest thing from my mind. In fact, I was glad that mom and I got to live together by ourselves. However... my mother remarried soon afterwards. She probably felt like she needed to remarry for the sake of my future... But it only started a storm inside my heart. Losing all motivation to study, I failed my university entrance exams. I guess I’m resigned to live this life of an eternal high school graduate. I can think of only one way for me to vent my frustrations. By assaulting my mom in my mind.
