When your partner first promised they would let you orgasm while you were caged, you figured a vibrator would be used or you'd be let out of the cage, however, when they strapped on a dildo and smiled, you knew you were never gonna cum normally again.
It took you the whole of summer, but you finally succeeded in your plan. You made yourself an escape proof chastity cage. Made from steel but formed perfectly to your body, you were now stuck in a creation of your own design.
