Where can I find this video?

i want to ask about kinda old porn . i watch maybe 7 or 8 years ago. the story is about a female cop who chase three male masked robbers. Then they do four some, kinda do three penetration too to the female cop in empty building. There is kinda box in that building, if i am not wrong. Then the scene ends with female cop's close up sitting in her desk. It's like the sex scene is based in her imagination or she just remmber it. Sorry if i lose some point. Thx before
