Finding a movie from yearly of 20xx

Hi, I'm looking for old movie from yearly 20xx, I remember approximate sequence of scenes: 1st solo girl at shower, then she came to strange building with dildo-statuette on reception, 2nd scene F+M in the kinda security room, 3rd sex in gym, 4th a girl found another one that masturbating in the office-room, then while she peeping she starts too, then begins a lesbo scene with double-ended dildo, the last scene was on the roof (maybe orgy or threesome). Pls help me to find the movie of my youth.
