This is an evil little chastity curse. It only prevents one person from giving you an orgasm – yourself. Everyone else will be able to push you over the edge, only you yourself can’t do it. You can vary the length of the curse by writing down a time between 1 day and 365 days before you start, if you don’t do it, the curse defaults to one day.
