When my Mistress first brought out the chastity device, I was very afraid.
I had begged her to fulfil my chastity fantasy months earlier, but she had never taken any action on it, save instructing me on the regularity of my masturbation - some weeks she would demand I masturbate several times a day. Other times, she would ban me from masturbating at all. I enjoyed these little games - especially since she demanded I report to her every small detail of my activities.
I was not afraid to wear the chastity device. Nor was I concerned about being deprived of orgasms - after all, that is what a chastity fantasy is all about. The truth be known, my Mistress's appetite for sex was insatiable. She liked me to fuck her as often as possible - several times whenever we had a session; she even liked to call me in the middle of the night, demand I come over and service her, then leave her alone to her peaceful sleep. Wearing a chastity device meant giving my Mistress all those good hard fucks was out of the question.
The first week I wore the device took some getting used to. It was made out of hard plastic. It was not an overly large device - designed to cover a flaccid cock with an additional ring to circle the scrotum. My Mistress had oiled my cock well, so my clammy dick never stuck to the insides of the casing. But at the end of that first week, my Mistress summoned me to a session, where she commanded I fully lick her cunt and trench out. It was of course my pleasure to perform this duty for my Mistress.
