I order my slave to get over to the desk and lie down on the floor. Then I place the office chair on his stomach and sit down on top. The weight of the chair and my body is concentrated on his stomach while I rest my feet on his face. He moans in pain from the pressure, but I won't let him go any time soon. He has to lick the dirty soles of my sneakers before I take them off and shove my sweaty bare feet into his face. He has to smell, kiss and lick my feet while I still crush him under the chair!
