SVDVD-550 Shame! Problem play correction naked physical fitness measurement competition

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. Even if you dislike it, take it off strongly, and say hello when the measurement is over. "Thank you very much". Punishment if the behavior or measurement result is bad. Spanking ●. And a male fertility test. Let them serve with their bodies, saying "Cooperate with friends"!
