A couple in love, thinking about marriage, have a tough decision ahead of them. They might have to move in with Tomoya's father. However that isn't even the start of the problem, upon showing up at his father's house, Kanako realizes that not only does she know his father... but she has slept with him… multiple times.

His father was a man of numerous partners. She was hoping that he had forgotten who she was, but he was simply too sharp. After she remembered what being with him was like, she remembered that he surpassed his son in every single way as a lover.

I tried to get my son, Kazuhiro, to help with the move, but he used his club activities as an excuse to refuse. Instead, Kazuhiro introduced me to his senior, Koizumi, who had graduated from school and was working in the moving business. On the day of the move, it was just Koizumi and me, but thanks to him, everything went smoothly.

When Koizumi brought up the moving fee, I found myself at a loss for words. The truth was, I didn't have the money to hire a professional, which is why I had tried to get my son to help. Seeing my predicament, Koizumi suggested that instead of money, I could repay him with sex. My sweat-soaked shirt clung to my skin, revealing my ample chest. Although my husband and I had been sexless for years, my body still had enough sexual appeal to arouse a young man's desires.

As I was hanging out on the rooftop, feeling down, Satomi Kawai approached me. I felt a mix of annoyance and temptation, knowing Kawai's reputation for fucking anyone when they were feeling low.

In front of the eager and flirtatious Kawai, I couldn't help but spill my worries. I was freaked out by the unexpected and bizarre appearance of my girlfriend's cunt during our first time, which left me unable to get my dick up. Kawai, listening with a smirk, brushed off my concerns, saying it was no big deal and would be fixed once we fucked. Before I could even wrap my head around it, Kawai stood up, flashed her tits, and brazenly exposed her cunt, giving me a teasing grin.

Final exams are approaching, so the protagonist gives up his activities in order to study. As Kawaii, the school slut, is not ready for the exams, he asks his friend to help him pass with good grades. He agrees to help her, since he can use that time to study and because she will reward him with sex.

After a few days of studying, the protagonist is left alone with Kawaii’s mother. As the two talked, the mother reveals to him that she knows all the kinky things he has done with her daughter. Just when he thought he was in trouble, the mature woman with huge breasts tells him that to thank him for all he has done for her daughter, she will let him have all the sex he wants with her.

Tomoko was worried because her son, Masanobu, was coming home injured, but he wouldn’t tell her the reason behind those injuries. Tomoko felt frustrated because she couldn’t help her son. One day, her classmate, Togawa, visited her. According to him, Masanobu was being bullied along with him. Tomoko continued talking to the young man until he confessed that the reason for his bullying at school was because he is a virgin. Seeing Togawa very distressed, she let him touch her huge tits to make him feel better.
