Your Face Used As An Office Chair

Ive some work to do on the computer - and since youve nothing useful to do anyway, your face will be my fresh office chair for the next few hours! Come over here and get down - and make sure to stay quiet. You dont want to disappoint your mistress and disrupt her concentration, do you?! Being under this divine arse should be an honor for you anyway - and I bet you bear the strangling and anguish gladly! Maybe I should get up a few times and drop my arse on your face again?! Or Ill simply keep sitting on your face until you stop struggling...!
