Sexual Mother's Pregnancy ~A Lewd, Masochistic, Big-Breasted Mother Becomes Her Son's Pregnant Wife~ Real-Life Version Himesaki Hana DASS-948

The protagonist, Kirimiya Haruta, is the only son of a wealthy couple living in a luxury apartment. He attends a prestigious private school but currently lives a semi-reclusive life. His father, Yoshio, is an elite employee of a large corporation who believes he is bullied because of his short stature and obesity. He despises this "loser" son and neglects his family, throwing himself entirely into work. On the other hand, his mother, Mizuki, a spoiled heiress lacking social awareness, dotes on him but understands little about boys' development, treating him like a child. He harbors a cold hatred for his father while secretly cultivating a twisted love for his young, beautiful, and charming mother. However, he doesn't actually fall into the life difficulties his parents anticipated. For several years, he hasn't been bullied and spends his school hours engaging in day trading to amass a fortune. He maintains good relationships with his friends and can obtain most things that money can buy. But I've now given up on the idea that "having a lot of money doesn't necessarily bring happiness." What I truly crave isn't money, but my mother, womanhood, and Mizuki.
