Today rain coater is a term that describes a porn movie that is as nasty as legally allowed. Pretty much the exact opposite of a couples movie, and tending to be so filthy and disgusting that you wouldn't even let your friends know you own it. That's a slight exaggeration, but it's closer to the truth than you think.
What you might find in a rain coater movie:
anal
double anal
double pussy
double penetration
cum facials
cum swallowing
cum swapping
gang bangs
interracial
spitting - not a big fan of this
slobbering - not a big fan of this
choking - think this should be banned
Then there is even more extreme:
fisting - usually available mail order only
scat - pissing or worse - mail order only
woof woof - mail order only
bondage and pain - serious shit is mail order only
Yep, there is defintely some twisted shit out there if you are deviant or freaky enough.
