Laura I understand your parents now, since they didn't know about chastity before, but my parents knew. I remember what other girls did, and it bypassed me for obvious reason so I had to study university's lessons only and I don't regret.
They knew about it before,and used it on me,but it was a punishment,not permanently wearing.
Laura I don't know how girls manage to go to school being belted. There is more freedom in colleges than in schools.
In my case,when I was belted,I take care of wearing clothes hiding it and was not belted when I've sports(but my chastity belt was put on me right after I came home).No mandatory sports at university,so no problem about it anymore.
