The cage had been locked on for months now, you could no longer take it and started signing up on message boards for anonymous meetings in public. You hoped they would give you pleasure and let you cum, but more often than not, you were just a play thing
You knew they were also locked when they asked to lock you up, but you had no idea they expected you to match the time they already had in their belt, and since she was Ace it wasn't difficult at all for her to last the 3 years she already had.
Its been 3 weeks since you got locked, you are not allowed any stimulation of your little clitty at all. This is what you have to resort to for orgasms now.
