The pain of the small cage and a plug that was 2 sizes bigger than you were used to was almost too much, but the pure pleasure you were feeling from the rush of arousal was enough to keep you going forward with your training.
You couldn't believe your progress. All the working out, denial, teasing, it was all coming together. Tonight at the party, no one was going to recognize you, and the fact it was a party known to have a lot of nudity, you were in for a wild ride.
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.
