Sex with my wifes best friend - 🧡 My wife wants me to have an affair with her best friend. What shall I do?

My wife and I have been married for nearly 20 years.

Everyone got drunk and they all started leaving or passing out my wife passed out hours before.

I know it takes two to have sex I'm at fault here as well , but that wasn't out first time drinking together.

Nothing ever happened in the past so something like what happened never even crossed my mind.

I stand before him in my panties and garters—and my glasses, of course.

We're not talking a girlfriend, we are talking about a wife, whom has been unfaithful multiple times with different people and shows zero remorse or care.
