Graduating
One week from now, once you've proven your commitment, you can find this picture of me and settle down in front of it. Bring a vibrator - a hitachi if you can afford it. Massage those balls, apply the vibrator, and try to orgasm inside your cage. I assure you it's an extremely painful and frustrating process. Take at least an hour.
If that doesn't work, you can try to milk an orgasm out by fucking yourself with a dildo or vibrator. Again, take at least an hour. I really want to see you come inside that cage. It gives me the shivers knowing you might never get let out again.
If that doesn't work... well, then we can get your key and unlock you. But you will ruin that orgasm, as completely as you can, and lock yourself up immediately. I want you to stay as frustrated as you possibly can be inside that cage. You can handle it.
