lewd@tthbaltazar I've done that in two kinds of public settings:
in sex parties, where people having sex is expected, and thus don't really need to restrain myself. people seeing and hearing me in that situation adds a lot to it.
and in more private "outside but trying to hide" settings, where......I can't help it anyway. it's too much for me. I usually rely on my companion covering my mouth or making me suck on their fingers or something. if it's someone with whom I fuck regularly they usually already know that and are ready to do that when needed
