Settle for the Original Wager; It's Bad Enough

You sense that you could probably shatter Erik's masculinity into pieces if you really wanted to, but you respect him as your rival, and decide to go easy on him. This wager was already the steepest that you two have ever undertaken, and you figure that leaving this room with his cock shackled is punishment enough.

Shoving Erik down onto his back, you straddle his hips, facing away from his upper-body and towards his defenseless dick and balls. You stroke him vigorously, and it takes a bit of time, but eventually the ceaseless teasing forces Erik's cock to stiffen between his legs. You grab up the chain, and quickly wrap it around Erik's balls, encircling his shaft all the way up to the tip before pulling it tight.

Erik shudders, and then you can feel his entire body go limp as the fight goes out of him. It was a close match, but in the end, victory was yours.

You drag Erik to his knees for a quick selfie with your phone, which prominently features Erik's expression of crushing defeat, and the chain that now binds his manhood.
