Mystery Mistress 8
You had expected a quick "yes." But it wasn't nearly that easy. Hayley pulled her feet back from you. And began negotiating. Not really negotiating, as you were in no position to make demands. More like laying out her terms.
One extra hour wearing the buttplug for every deep sniff. Or, you could smell as much as you wanted if you wore it for the rest of the day. You were obviously all-in.
Next condition: you could have one lick if you wore plug for an hour tomorrow. You would easily agree to that. Or, the final upgrade offer, unlimited licking today if you agree to put anything up your ass, at any time, whenever she asks you to. You hesitated on this one. That was a big unknown. It would allow Hayley to force you to fuck your ass with any object, no matter how big. Baseball bat? You made the deal, gotta make it fit. Or any time. In the middle of a meeting with your boss, Sativa? Tough, thumb up your ass now! Or what if Hayley had a gay friend that might want to fuck you in the ass? This was too much, you couldn't accept that deal.
