When a guy says to a girl; lets play the firetruck game, he cons her into touching her pussy.
Guy: Let's play the firetruck game.
Girl: OK, how do you play?
Guy: Well I run my hand up your leg and when you want me to stop you say "Redlight"
Guy: -runs hand up leg-
*5 seconds go by*
Guy: Firetrucks dont stop for red lights ;)
