Fans of "Oopsie!" know what they're getting, though the Adult Time label does it best to mix the content among stovepiped porn genres like trans, Gay and BGG. While the title suggests dirty talk, "Potty Mouth" is a tedious 3-way involving interracial sex, and suffering from its awful male casting.
That awful male is JJ Graves, an unattractive guy covered with ugly tattoos who's assigned to hump two attractive females. In easily the dumbest set-up scene in memory, he disguises himself as a toilet seat (you gotta see it to disbelieve it) and then has sex with veteran Misty Stone and busty newcomer August Skye, who would much rather he bowed out to let them have lesbian sex one-on-one.
Misty trots out her favorite pornspeak with her favorite line "Oh my goodness!" but manages to swear a lot anyway, perhaps it's blasphemy that she likes to avoid.
