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 butt should be an honor for you anyway - and I bet you suffer the throttling and agony gladly! Maybe I should get up a few times and drop my ass on your face again?! Or Ill simply keep sitting on your face until you stop struggling...!
