Defy this new rule

"What a stupid rule, i won't cage myself." you tell yourself as you go to college the next morning.

But at the entrance door, the college security (all futa guards) stops every male and has them drop their pants to check their chastity cage. If it's not on the list of approuved cages, they are sent away and told to come back when they have a good one. But those who don't have any have their name written on a list and are told that they are hereby expelled.
