I'm currently re-reading "Hells Angels" and am amused that one of the most common criminal charges filed against them in the early 1960s was "public cunnilingus."
Sadly, Hunter S. Thompson never says where the public cunnilingus took place. Do you think they were eating women out in bars? Or in the middle of the street? In church? Where exactly would someone perform public cunnilingus if they were so inclined?
