You have been a very naughty slut and wore a thong outside despite me, you Mistress, telling you not to. As you were bending over at a shopping aisle a guy saw your thong poking out of your pants and now threatens to expose you unless you suck his cock until he cums in your mouth and then swallow every last drop.
You ask my guidance and like the generous Goddess that I am, I decide to help you and instruct you on how to suck his cock the best way possible.
Are you ready to serve slut?
