My wife really enjoys being on-call lover for him

My wife and I are both 22. We've only been married two years, and already she is the mistress to a multi-millionaire older gentleman. I don't really know how to control this situation. My wife really enjoys being "on-call" for him.

Apparently, he "needs" her a lot. He's always ordering her to come to his mansion so she can suck him off or fuck him. I like the fact that he gives her lots of cash, which she often spends on me, and I like hearing all the sordid tales of how he fucked her, but deep inside, it's still a very humiliating feeling knowing someone else is taking your wife away and fucking her whenever he wants. I just wish that idea didn't turn me on so much.
