Blue - jerk Red - stop and Black - explode

I recently added new pairs of SleekCheek vinyl leggings to My collection and you begged to see Me wearing them. Its the week of My birthday and I feel generous; I offer you the opportunity to enjoy seeing My voluptuous butt in every pair that I own. But there is a price that you have to pay: you have to perform a separate task for each color. you will rub your dick when you see Me in the blue leggings, you will keep your hands away when Im wearing the red ones, and you can finally get ready to cum at My countdown when you see Me in the black pair. Are you ready?
