Like Fish to a Line

So here's a question for a lovely Tuesday morning: Imagine that you're well-ensconced with a significant other -- hell, let's say you're married. One evening, a mysterious and altogether captivating hottie strolls into your life, and you have the opportunity to engage in back-breaking sex with no catches, no obligations -- and no chance of your partner ever finding out. You simply indulge, then walk away a free man or woman, back to your life of romance and hottubs and martinis and robot butlers (oh, like you don't have one).

Do you partake? Or pass on it?
