In a class of only S-class beautiful girls, the boys are in a harem state! What's more, the naughty girls in my class play pranks such as flipping skirts and shifting jerseys, and seeing panties show off every day! Sometimes my buttocks are visible and I get an erection! The pranks escalate, and finally the girls are tied to desks, chairs, etc. and left alone with a sign saying "Please feel free to do it!" When I found this, I did a lot of lewd things! Freedom is good!
