What's the best way for a beta white guy to serve?

My wife’s sex life is hers and I’m along for the ride. When she’s with someone and wants to do something wild like fuck in public, pick up a woman for a threesome, or just go out on the town. I’m there to help them accomplish those things. I also enhance those fantasies when she wants by being the cuckold in the room or at the restaurant table she can taunt.
