I did see her when I clicked on Freddy's boobs in the poster multiple times. You'll hear someone say 'stop' whenever you click.

The poster in the office does not give you a sex scene, it is only a jumpscare. If you touch fredina's boobs 7 times, each after she tells you to stop, then golden freddy will jumpscare you, and you will not get any sex scene. The poster with golden freddy is on cam 3 on the monitor, which you have a chance of seeing golden freddy's face on.
