One of the chastity devices i have come upon is the Kalis tooth braclet.
i do admit to owned a 24/7 version which is mild when you get used to it..i upgraded to the extreme one which i will admit was difficult to get used to but wore it a lot and got addicted to it.lucky i was not serving or submitting to any one at the time...but i did wear it for day and night for 90 days... i make no secret of the fact that it makes your mouth hunger...it drove me insane..but you know you have to test drive a product in order for Your Mistress to get the best out of you... i would be dumb enough to seek a Mistress for chastity...it is very addictive...submission to arousal in this device makes sex very ordinary..its like watching a vanilla blue movie when your into bdsm...boring.. to watch..
