Getting a hardcore blowjob from one's partner, in the vicinity of an automobile. An authentic Ms Hiromi is performed with that partner's guardian driving the car, and both participants in the back seat.
"Dalton, what did you do over the weekend?"

"I hung out with my girlfriend, she gave me a Ms Hiromi while I was talking to her Mom in the car!"

"Nice."
