That’s it. I want you to take your panties off, but leave the stockings and garter on. You may have to unfasten and then refasten them. Take your time, and don’t put those panties too far out of reach.
Now, once you’re ready, I want you to lean back in your chair and put both feet on the desk. Lean back with your legs up high, and spread apart.
Now stroke.
Imagine you’re about to take my strap on. Imagine I have you bound to that chair, and I approach you wearing my thick, black, shiny, lubed dick. Imagine it filling your sissy, feminized ass while I stroke your cheek and whisper:
“You’re mine, slut”
