OK slut welcome to the first part of your little panty punishment. Here's how its going to go. You have three pairs of panties to wear right? So we have three different stages of the punishment..each one a little more.."fun" than the last. If you bitch out or cum too early you will have to wear the panties you are wearing during the stage until you can man up and finish the whole tease! Got it!
Now start stroking that tied up cock through your cute little panties. What color are they? Where did you get them? You love panties don't you? You better be naked except for those panties slut..NO exceptions!
All set? You better be! Good.
Now get out that wooden spoon or something "fun" you got from the kitchen. Don't act like you have never wanted this before. Stop stroking that cock!
I want you to look at the clock, or better yet set up a stopwatch on your phone or computer. Keep those panties on and spank yourself alternating each cheek for a whole minute. DO it NOW!
When you are done look at your sorry ass in the mirror and see the nice little pink spots. Now pull down those panties and do it again. As hard as you can for the FULL MINUTE. No cheating here sissy. Make it hurt!
