You've been a good little slave. Always so obedient. Doing whatever Mistresses wishes. Always doing everything you can to make me happy. Well Mistress has a reward for you today. Today I will allow you stroke your cock while you worship my ass. I also have your favorite gloves on that I will use to stroke your cock occasionally. You, lucky slave, get to worship my ass and stare at my breasts until I tell you to cum with your tongue buried up my ass. That's right you are a lucky one. Pull out your cock and let's put that tongue to work.
