The overly developed female manager was subjected to intimate sex in a private room, pressed tightly against his sweaty, implanted penis. (Shishido Riho, SAME-152)

A teacher's job is just tedious and boring. I just want to live by doing biological research. But that alone isn't enough. Even if I didn't want to, I had to be the baseball team's advisor. However, recently I've developed an interest in someone. A female manager, Miho Rin, with excellent grades and a serious personality. Her well-developed body is evident even when she's clothed. I want to get that body pregnant. I can't resist my destiny as a biology teacher and my instincts as a man.
