Ever caught your partner cheating and then invited the affair to join the relationship?

My wife allowed me to invite my longtime girlfriend to join us. She accepted and we had some fun over a few sessions but they were jealous of each other and my wife was far more willing to pleasure my girlfriend than my girlfriend was my wife. My wife is an experienced bisexual having had several lesbian relationships. It was entirely new to my girlfriend. In the end it didn't work out but it was fun while it lasted.

Anyone who would do that is already in a poly relationship. Only way I could see it is if a hetero partner finds their partner did a gay cheat. Like a dude whose girlfriend starts seeing another girl. Some guys would think that's totally awesome. Same with girls whose boyfriend starts seeing another guy, I know that's a big fantasy.

But only for kinda shallow relationships. For a deep relationship, the betrayal is probably outweighing the sexiness.

I am pretty sure that wouldn‘t work that way at all in real life. So don’t try this at home!

I've "heard" of the opposite more often than I've heard of this case, (outside of porn of course). Where someone figures out their partner is cheating, contacts the person the partner is cheating with, and they both devise to "dump" the cheater.

I hate to break it to you, but porn isn't real life.

In a relationship built on exclusivity, running into your partner having sex with someone else is a shock for everyone: the one who's cheating, the one who's being cheated on, and the other one. I've been there.

The moment your love life collapses, you don't wonder if this isn't the opportunity to spice up your sexual life.
