Wow baby, that's really dirty! See, I knew there was a slut lurking in you!
Here's a video of my favourite way to treat one of my slaves, I want you to watch it and stroke anyway you like, but you must keep stroking. You know what to do if you edge, pause it, ruin it, dribble it honey.

Then I want you to look around the internet for a video of a shemale that is as close to the fantasy you described as possible. You must then stroke your cock and watch it. Same goes if you edge sweety, I hope it's a short video!
