Jen Wow, very nice! Your parents found a good way to distract you, and perhaps a reward for your dedication to staying chaste as well? It must be something that esp. your mother will be pleased with.
I hope there were breaks in between? 3 hours is a row seems too much.
How many hours towards your license do you have by now?
Jen I still need breaks from the belt
Is this still your skin getting annoyed? You have not managed to find a product that relieves that, like the talcum Jonas mentioned? Perhaps one of the other wearers here has another tip for you? I heard vegetable or baby oil being recommended.
I also heard some people just removed the lining, and wear the belt metal on skin.
Of course once you get through this and decide this is the way to go forward, a second belt or a different waistbelt (if they can be exchanged on your current belt) that sits at a different place could help, but that would be a pretty expensive option. It's hard to judge, but the lining on the FancySteel FS2 looks different from the regular silicone.
How long do you usually need to give the skin a rest before you are ready for more belting?
