Three female students who are usually members of the discipline committee. They get good grades and live their student life seriously. But that's just a disguise. They're actually super slutty sluts who love to play with men's nipples! These devilish beauties get excited by the look and sound of a man's pleasure, and they're going to thoroughly play with the nipples of the new teacher, the head of the grade, the student teacher, and the principal, training them to be super masochists!
