What could be the possible plays/acts if you are meeting a hotwife & cuck husband?

As the title says, I have been invited by a married couple where the guy is a cuck & she's a hotwife.

My question to experienced people out there ( Kinksters, Roleplayers IRL, Cuck-Hotwife, stag-vixen, ENM/Open couple ) that what things you can try with them? They asked me that they wanted to explore that dynamics.
