Mark takes you on the spot

Bent over at the waist, you hear something unzip behind you. You momentarily try to peer behind you, but your submissive personality keeps your hands gripping your ankles. You feel both of Mark's hands take hold of either side of your waist, and he pushes in closer. His stiff member wanders in between your cheeks. You can't help but begin to inhale and exhale deeply, snapping your head back forward, waiting for the inevitable. He does you a favor, and handles his meat to scrape against the outside of your labia. Slicked up with your juices, you feel his hands tighten once more around your waist, and he pushes himself forward.

All the build up has gotten to you. The notebook. The coffee shop. Your boss, and the email he made you send. And now this. Reality begins to sink in as Mark's dick sinks into you. You can't help but release a helpless squeal as he makes use of your new position. Unsure of what else to do, you grip your ankles tighter and tighter for balance, even though it is Mark's hands and thrusts that really matter. Pretty soon the sound of your aroused sex and Mark's thrust fill the office air. You can't imagine how anyone nearby can't hear. Add on to that that you are helplessly bleating in unison with his grunting.
