I've some work to do on the computer - and since you've nothing useful to do anyway, your face will be my new office chair for the next few hours! Come over here and get down - and make sure to stay quiet. You don't want to disappoint your mistress and disrupt her concentration, do you?! Being under this divine ass should be an honor for you anyway - and I bet you endure the smothering and pain gladly! Maybe I should get up a few times and drop my ass on your face again?! Or I'll simply keep sitting on your face until you stop struggling ...!
