Not that I remember, though I can immediately think of the advantage of doing away with the "husband has a cuckold fetish" trope. But on the other hand, the writer would have to go out of their way not only to make it tasteful, but to convince readers it doesn't come from the wife's frustration, that she wants it because she likes teasing her husband, not because she needs other guys in her sex life. Then, they'd have to think of how the husband would react. I know some of you are ok with guys allowing it with no other gratification than showing their love for the wife, but I can't go there. The way I'm wired, partners rely on each-other in a relationship, complete each other. There must be no need for either to rely on others for anything (I won't go into situations where one has some condition that prevents them from satisfying their lover, heck, I'm looking for light entertainment, not drama). So, everything involving third parties should be recreational only, an extra to spice things up. Having said that, I don't see why the crazy idea can't come from the wife, just don't remember any games that bring it up that way.
