My biggest fantasy is either of my female staff coming on to me. If I make the first move I could lose my job. If they make the first move, I guess it depends on how I play it...
They are so different from each other, but I would love to spend hours making either of them cum multiple times.
It won't be the most obviously taboo fantasy on here, but it is taboo because it could destroy my life, and I can definitely say that I would, without hesitation, LOVE to bury my face into either of them, and I think about it frequently when I talk to them.
