Revenge on the tiny cheater

We need to have a talk my darling, did you think I wouldn't find out? How silly of you. I will have my revenge on you as I always do... It took me a while to think of something to do to you, to think of how best to make you suffer, so I came up with a plan... After one simple deal with a Devil, I have been granted magical powers, and I'm going to use them to shrink you and your little slut into my tiny playthings!
