Femdom sjuksköterskan: valet av kyskhetsburet

Hello, I am a nurse but not a traditional nurse, my goal is to put all the small cocks in chastity cages and transform the guys with useless cocks into submissives who beg for me to empty their balls. But their balls empty on their own after a few months in a chastity cage. However if they were perfect, I can consider fucking them deep in the ass to help their sperm come out but what I like the most is seeing them suffer and at that moment as I am a nurse, I know how to make you suffer even more
