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"? I can't tell anyone about this problem. I wonder if my homeroom teacher, Mr. Tanaka, would understand my worries...?
