Go inside anyway

You go inside through the front entrance. Sneaking in from behind might even be more dangerous than just walk in through the regular entrance. You go through the door and find yourself in a long narrow corridor with lots of pictures of scantily clad women on the wall. One of them is wearing a bikini, another is not even wearing a top but uses her hands to cover her breasts. You get hard inside your pants.
the corridor goes around a corner and you peek around seeing a security guard standing there. Great. What now?
