We had a situation like that when camping.
A lot of moaning and groaning, "Oh yes baby", "Oh yes baby", "Give it too me", etc... coming from the camp site next door ( fold down camper ).
Solution: Re-enactment of the shower scene from "M*A*S*H".
A dozen people sitting in lawn chairs give the performers a "standing O" when they come out.
Strangely quiet over there the rest of the weekend.
