Good boy, you better be back down on your knees. Now I hope you don't mind but I started getting a little hot watching you tug on your balls all over the office and had to get comfortable. How is My cock doing. Is it leaking yet? Whipe up that nasty precum off with your index finger and shove it in your mouth. Tell me how it tastes.
Now I wonder, have you ever had anything in your ass before? You have! Good. Now lube up that butt plug and slide it into your ass. You better hold it in there. Every time it hits the floor it is going into your mouth for a thorough cleaning and then back in your ass.
Now untie the shoelace from your big toe and make the tie on your balls tighter. Put your belt on as tight as you can. Pull the string behind you, through your legs and tie it to the back of the belt. Leave as little slack as possible. Your balls should be pulled tightly behind your thighs. Make sure all the ties are tight! This should keep you humble in my presence.
Now tie your ankles together with the rope. Use quadruple knots. If anyone comes in you wont be running off quickly to hide.
