The hard plastic cage covering your privates didn't let any sense of feeling through, but for some reason you tried to still tug on it even if you knew it was a hopeless endeavor.
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.
When your partner suggested you try some bondage to spice things up, you never imaged it would start with 3 weeks of chastity followed by a shibari session ending in free use for all your partner's friends.
