Satin Panties Guessing Game

I want to play a little game with you! A masturbation game involving sexy, satin panties. I have ten different colors and Ill be wearing them one by one. As long as you guess the color that Im wearing underneath my little skirt, you can stroke until your next answer. If you get it right, you can continue stroking. If you get it wrong, you have to stop. Right now why dont you work your cock up for me? Get it nice and hard while I tell you about all these different colors so you can be sure to get them right. *Tip: if you can keep track of all the colors I wear, youll get the final pair correct and youll be able to stroke while I give you a cum countdown!
