What a bag of M&M's means

Sometimes everything becomes more exciting when I am challenged, and I know that a prize is at stake should I win the bet.

The prize? A big bag of M&M's chocolate-coated peanut candies.
The challenge? To exceed performance in bed.
The result? I won, hands down!
The secret? Unparalleled energy which I only usually experience after some serious exercise, waking him up with a serious blowjob, and staying on top the whole time.
