Role play scenarios?

For group fun my wife has worn her wedding dress for the men.
Also catholic school girl outfit

One of my strongest bucket-list fantasies is for wife to play the "cheating wife" role, where she only drops very subtle hints of her play session(s) but denies that anything happened. Soooo erotic for me to think about it.

Here are a few we have done

Goth guy/popular girl CNC scene
Douchey frat bro/Studious academic chick
Mob boss/woman whose boy friend owes a debt
Inquistor/witch

One we want but never have done
Personal trainer scene

We've either hear of or made up the following: model/photographer, doctor/patient, nurse/patient, doctor/nurse, priest/nun, bride/best man, pagan fertility ritual sacrifice, jail guard/prisoner, massage therapist/client, handyman/bored housewife, professor/college student, stripper/customer, punisher/sinner (this one is heavy on the BDSM), queen/slave, priestess/worshipper, and party game loser tied down available to all. Any others you've done, witnessed, thought about, or heard about? Favorites?
