Ok, being for real, no judgement, but what would be your reaction if you found out that your coworker did fetish work? An to make matters worse, it's your fetish. Oh, and don't give me that answer, "I would respect their privacy." NO. Here's the kicker, unbeknownst to you, your other coworker also found out and is about to inform the coworker who does the fetish work the next day in the afternoon. Now, here's the REAL kicker, there's a 100% chance she's super into this fetish but never found someone to enjoy it with. Now, knowing this information, do you tell your coworker in the morning and perhaps something kinky between you two happens? Or do you keep quiet, see your other coworker tell them in the afternoon and they become an item and eventually married? Don't worry, you'll get an invention to the wedding.
