Chapter 7.1
Eiji and Koichi are such good friends their colleagues think they’re dating. Since being roommates in the same dormitory some 20 years ago, they’ve gone through the same university, the same company, and living the married life under the same building. One day, they both find out that their wives want a divorce. While drunk and consoling each other, Eiji shares his troubles “down there” and it turns into a competition of who gets to make the other come first.

It's fully erect, y'know?" Eiji and Koichi are so close that their coworkers think they're an item. They roomed together in high school and have been inseparable ever since. They went to the same college, joined the same company, and even rented the same apartment building after marriage. But then, both of their spouses file for divorce! As they drunkenly console each other, the conversation turns to Eiji's erectile dysfunction. Koichi pushes Eiji down, saying he will "compare it with what it was like 20 years ago." Before long, they're both engaging in mutual masturbation and making each other c**?! What will become of this 20-year-old mutual love affair...?
