A competition, and you plan to participate

Next to the stage are some signs, informing you of the opportunity to partake in a competition. The goal seems simple-volunteer men and women get up on stage, and the woman which gives the best blow- or handjob, and receives the most impressive cumshot, wins.
An idea begins to form in your head. You quickly find the woman which holds the competition, and whisper some things in her ear. Then you go to look for Lydia.

You find her with John, by a stand with chastity devices. Right now, shes handing John an even smaller cage, maybe 1.5. inches. ""hat do you think?" she asks, then she sees you. "Ethan! Hows it going?"
"Good, good, listen, can i discuss something with you?"
You pull her aside and leave John standing there, the small cage in hand. Some goth girls walk by and giggle as they see him.
You explain Lydia your plan and her eyes light up. "I love it! Thats gonna be so much fun!"

You spend the next half our just walking around, until the speakers inform the guests that the "competition" was about to begin.
As people take seats around the stage, you begin to feel a bit nervous. Cameras are prohibited, and you really have nothing to hide, but stil...

Some men and women are being called up to stage. Some bigger, some smaller, none as big as you. Some fail to get hard, over manage to cum rather quickly.
Then, finally, you sense your chance. As the lady on stage calls for a new competitor, you raise your hand. She smiles and waves you on stage, flirting with you, doing the usual showbiz stuff.

Then she turns back to the audience.
