Giving a Rimbjob and Milking a Cock

I am submissive slave, i love to listen and obey. My master want me to lick and stick my tongue in his ass, giving him a rimjob. I like to taste his as and stick it deeper . His cock is so hard and struggle not to cum so fast. I milk his cock while i lick his ass. After i blow his cock one more time, he comes on my beautiful big tits. Such a delight!
