羞恥！問題児矯正全裸体力測定競技会

Ignore impure heterosexual exchange, late addicts, and teachers. Gather problem students and teach them greetings, etiquette, respect, and shame. Let them compete naked in front of everyone. Forcibly take it off even if you dislike it, and say hello when the measurement is over. "Thank you very much". Punishment if the behavior or measurement result is bad. Spanking cage. And a male fertility test. Let them serve with their bodies, saying "Cooperate with friends"!
