I don't know what you think a "quicky" is, but I'm a New Zealander and I know. Some guy who says it's between "1 and 20 min" wat the fuck? Here in NZ that is a "normal shag". A quicky is done in the quickest possible ammount of time (the time it takes to get an erection and blow your load as fast as possible). They take anywhere from 20 secconds to 2 minutes. The only one getting any pleasure is the guy - the woman is only there to help the guy out, and doesn't recieve any real pleasure.
The act of intercourse in a short amount of time (usually under 3 minutes) where the male recieves the majority of the pleasure, as the females sexual peak has been known to come later (all though no one cares)
Thomas and Kelly went into the stall at the resturant for a quicky as it was Thomas' birthday
