Boys Only Sex Classroom: Hot-Blooded Hole Training, Please!

Kono's never cum in his entire life, so he pays a visit to a "Male-Only Sex School" that can supposedly solve his problem... there, a hot teacher named Yoshioka suddenly starts teaching him how to masturbate correctly! He can get hard, but for some reason, he can't cum! "Don't think about anything. Just leave your body to me" Then, suddenly, Kono's teacher starts touching him down there! Teased, licked, sucked... and then the finale - a prostate massage! Will Kono's poor penis survive all this fantastic therapy?!
