Mistress Ava Black has her chastity slave ready for his device fitting...
But lo and behold, as soon as she tries to get his cock into the device he manages to catch a very unfortunate boner.
Oh goodness! She is definitely not pleased with that!
So she decides to solve that problem one way or another. By stroking it to get him to spunk, and then by slapping the cock as hard as she can. All while sitting naked on his face to make sure he spunks as quickly as possible.
Will she be able to get that cock to 'get down boi!'?
