Some rope and a vibrator

You quickly return with a vibrator and some rope in your hands and Mia has a cheeky grin as she sees what you've got.

"Mmmmm are you gonna tie me up in this chair daddy?"

"You guessed it whore. Now let me get you out of those clothes."

You pull her tank top over her head and slide her panties down round her ankles so she's fully naked, except for her 'whore' collar of course. With that done you start tying her up. First, you wrap some rope around her ankles, tying her to the legs of the chair so they're wide open, fully exposing her pussy. Next you tie her hands behind her back, passing the rope through the chair so she can't shift forwards or backwards. The final step is attaching the vibrator to her pussy, which you do so by tying a rope around her waist and the handle of the vibrator, holding it firmly in place against her clit and lips. As you switch it on and turn it up to the highest setting, Mia lets out a moan and looks to the ceiling as pleasure flows from her crotch. Thinking this might get distracting, you need to find a way to shut her up and so you grab her panties from the floor and stuff them into her mouth. Her moans are still audible, but much quieter now.

With Mia stuck in this position and the vibrator buzzing away against her pussy, you move over to the TV. You find your way to a porn site and search up 'rough gangbang'. This was some of Tracy's favourite content so Mia would probably love it too. Playing one of the first videos you find, Mia watches on wide eyed as she's pleasured by the vibrator whilst simultaneously being turned on by the porn scene unfolding before her. The video is a full length porno and will keep Mia entertained for over an hour.

"Alright then whore, I'm gonna go do some work while you stay here. I'll be back to check up on you later. Oh and remember, no cumming until I do get back. Understand?"

Mia tries to say something to you but with her panties stuffing her mouth it's unintelligible, but it sounds vaguely positive.

You leave her like this and head to the study to do some work. As you take a seat and put your phone on the desk you see another notification come through from Adrian. You already have 32 photos and videos and wonder if you should watch them before you start working.
