Hentai Chastity Lottery
Now, choose CBT or no CBT. (if you wonder if this could get dangerous : NO ! your health shouldn't be threatened at all !)
CBT is advised for more fun !
Write your choice down, then go to https://www.random.org/ , generate a number between 3 and 48 and go to that page. You'll do that at the end of each page.
You should also open another https://www.random.org/ page, because you'll sometimes have to generate other numbers. Leave both of those pages opened at all times !
On the same paper, if you chose to do chastity, you'll keep track of a "chastity counter" which will increase with some encounters. For now, it is empty. Whenever you're told to leave the tease and not to come back until the chastity expires, that chastity time refers to the one written on your paper. You cannot wank, or watch any other porn during that time.
Obviously, if at any moment you can't hold back any longer, stop and come back when you're ready to proceed. You'll keep your progression.
The ones you should seek are the Mistresses. They are the ones that will allow you to cum. But some of them are evil, and will increase your chastity or give you a very long list of instructions. With that said, good luck!
