Kourtney K. & Travis Barker Kissing on the Dock of the Freight ... PDA Wherever, Whenever

Travis Barker and Kourtney Kardashian must be trying to set a world's record for public face sucking sessions -- and they must've had Otis Redding on the mind for their latest location.

The couple was standing on a dock -- the loading variety -- in NYC for Tuesday's hot and heavy make-out sesh. They were in the middle of a shopping spree when they decided to load up on the PDA.

Luckily for Kourt and Trav, there weren't any deliveries going down, but let's face it ... that loading dock isn't gonna see any better action than this. At one point, Travis kinda had his GF pinned against the side of the wall as they went at it.

It's kinda funny ... you can see there's a max height of what movers can shove through the docking entryway -- less than 11 feet -- and KK's well in the clear at just 5'1" and Travis is 5'9". Safety first, kids!

Anyway, this is what these 2 are known for now -- be it in Italy, Malibu, Paris, Mexico or even New York ... they're gonna lock lips like it's the last chance they'll ever get.
