Increasing the thrill by trying to finish cranking one off before you are caught
The object of danger wanking is to entice yourself into a sense of security, then your climax makes you grunt and BOOM they've seen you.
***Open your bedroom door***
***Unzip your jeans***
***Whip out the one-eyed-milk man***
***proceed to Danger Wank***
you must finish and put everything away by the time she gets to the top of the stairs...
On a long journey in the car:
Sit in the back, while someone else is in the front
whip out your lolipop, and proceed to wank
you must finish without rocking the car off course, atracting attention in the rear-view mirror, or making an audiable sound.
go on, try it....
don't do it for you, do it for the little guy

Guy 2: "DDDDDuuuuuuuuuuuuuuudddddddddeeeeeeeeeeeeeee"
Guy 1: "No, it's ok, she helped finish me off"
