YUJ-047 | Teacher, please teach me how to give a blowjob after school.

Until recently, I had lived my life without knowing the meaning of the word "fellatio."
Everyone around me knew, and I was treated like a bit of an outcast.
How can I learn more about "fellatio"...
It's a problem I can't tell anyone about.
I wonder if my homeroom teacher, Mr. Tanaka, would understand my worries...?
