Mystery Mistress 9

Mystery Mistress 9 by thedude234

It started with who would be the worst person to have your key. Sativa, your boss, was clearly the top choice. She's the last person in the office you'd want to share your secret with. The last person you'd want to beg to unlock your cock.

But you shouldn't ever have to ask. Because Mistress Fire said that 2 keys at a time could unlock you. So you would never have to ask Sativa, you would just have to find the other person with a key matching hers.
