Is there even a proper term for it?
Hey, @Odysseus of Domntr, you might be on to something. Maybe invent a new term? Kinda reminds me of the '90s and below where the terms 'pegging', 'dirty sanchez', 'santorum' are being invented. (most recent I can think of right away is 'mating press')
Just not this term "oromanstupratio" - copy/paste that word on google and it will bring up a different meaning from what you are giving.
