My name is Danjuro Kurobuchi. I'm a middle aged teacher. My students call me Nikujuro and ridicule me. The staff shun me. My only social life is when I pay a hooker, and the condom that separates us is a metaphor for my relationship with the world. Vice principal Harada burdens me with additional duties after school hours. My pay is low, so I end up roaming the halls doing menial work.

One day I see one of my students, a slutty "gyaru" type named Mika. She's habitually truant, sleeps in class... it's strange to see her still on campus. She goes around the side of the building, and I follow her. She starts making out with her boyfriend. Being a morality officer and a teacher I need to investigate this lewdness. That is to say, I watch them f*ck from beginning to end. When it's all over, I'm all pumped up and horny from peeping. I go straight to the red light district. While I'm walking between the sex parlors, Mika suddenly calls to me. She followed me here. I stop dead in my tracks. She grabs my hand and excitedly takes me to a nearby hotel. She knows that I was watching her earlier and bribes me not to expel her. She wants me to stay quiet. In return...
Mika and I f*ck in the tawdry, cum-stained bed. It's wonderful. Her soft young wet p*ssy glides effortlessly on my d*ck. She lets me cum inside her. I'm cumming in my student. We do it until morning. And it doesn't stop there. She wants to keep doing it. Not just a one-night stand...

She's only the first of several students. The president of a club, a bullied girl, a delinquent girl, they all have their reasons. My so-called sex life is exploding.

Four girls together - a sex vacation to the lodge?
They have these questions for me... I solve everything with sex.
Finally I feel like a teacher!
