Chad held up a metal ring with about a one and a half inch diameter. It was a plain silver ring except that it had a tiny switch on it. The switch didn't do anything so Chad wondered what it was for. The ring was way too big for his fingers but too small for his cock. Then he noticed that there was more writing on the note.
"If you don't know what this is, it goes on your balls. Slip one ball at a time through the ring and then flip the switch."
Chad struggled to get the ring on. It was big enough but only for one ball at a time and his two did not want to cooperate. Finally, he got both balls through and he flipped the switch. The ring shrank. That's all that happened. Chad was still Chad but there was now no way to get his balls out of that tiny ring, not even one at a time.
Chad couldn't figure out how the ring shrank or how to make it grow again. He flipped the switch back and forth but nothing happened. He let the ring go and it felt heavy like a pound of metal pulling on his balls.
Chad waited, wondering what kinky plans Karen had. He stood there naked, waiting for hours. Then he felt like a fool. No one showed up. At eight thirty, he gave up and got dressed. He wore the metal ring around his balls because he couldn't figure out how to get it off. He went home and got ready for bed. He planned to sneakily ask around the next day to find out who had stood him up.
As he crawled into bed, he could still feel the weight of the metal ring permanently attached to his balls.
