He buys her sunglasses

Where can i find a movie where a guy meets a girl on the streets ( she was american, i am sure so it wasn't from public pick ups) starts talking to her and buys her something from a stall (sunglasses) then he tells her she is beautifull and stuff and invites her back to his place for a photo shoot and, of course, they end up fucking POV style. I remember the girl had blonde or light brown hair and a very nice ass. The unique part of the movie was that the guy buys her a pair of sunglasses as a gift in the begining whyle they were talking and walking around near some shops . Please if you have any ideea about the movie tell me.
