Imagine being locked into a strange device, unable to move your entire head as it pokes through a small opening in the middle of a cushioned seat! As you lie down on your back, looking up at the ceiling you quickly realize that you will be serving as Ms. Katherine Green's human seat! Her perfect round ass comes into view as she lowers herself on top of you, your nose and mouth are entirely covered by her ass! She rocks back and forth, only letting you breath as it pleases her. You are her slave and will serve entirely at her pleasure. Today seems to be your lucky day.
