Supervised playdates roleplay fantasy

One of my big roleplay fantasies is to have a playdate with another "little" (any gender, for some reason my sexuality feels less rigid when it comes to ageplay) while supervised by our partners/caregivers. There would be some sort of erotic element, which could be as innocent as being changed or spanked bare-bottom in front of each other, or more explicit, such as being encouraged to cuddle and explore each other's bodies.

Does anyone else share this fantasy, and/or have you engaged in this type of play?

I think it would be interesting, however I haven't done much role-playing. I would like to try it in a real setting or possibly with a small group.
