But for now let's concentrate on the job at hand... namely locking your cock into chastity. I know you want me to be mean to you, you've told me a million times that nothing turns you on more than my cruelty. Which is great, because I intend to make your chastity a living hell.
Once your cock is locked away I'm going to be wearing a lot less clothes around the house, and seeing your need grow is going to make me very, very horny. Which means you are going to be spending a lot more time with your face buried between my legs.
But at the same time, since I know you love doing that, it would be wrong to let you do that every time - wouldn't it? You wanted a cruel Mistress after all, so quite a lot of the time I'll probably just make you watch me get myself off, with my fingers or one of my dildos... if you're lucky I might let you lick my toys clean afterwards.
Or maybe not.
You see, my objective here is to make you ache... for me. I want every waking second of your existence taken up with longing for my body. I know you think you already ache for me but believe me you don't. Not yet. But you will.
Give me another 100 strokes, then...
