My Big Diaper Princess has been fully regressed and now is trapped wearing diapers for the foreseeable future. He lays on the bed protesting to me about his predicament; I whisper to him that yet again he is going to be denied my pussy and his useless little pee pee will remain tucked away in his pink diaper as I torment him! I intend to make use of him today but not in anyway that will give him any pleasure - I instruct him to lay down on the bed and I start by straddling his face, placing all my weight over his mouth and nose, covering him with my voluptuous bottom. I laugh at his predicament as I start grinding myself back and forth on his face, the crinkling of the diaper can be heard as his legs squirm in frustration from this torment. I can feel myself getting rather wet, his nose touching my clit with each grind, harder and faster I go as his cries are muffled from my flowing juices. I look down and can see his little pee pee growing hard and pressing against his diaper - all the time knowing that it will never see the light of day again! Having thoroughly pleasured myself, I lift myself off, laughing at his soaked gasping face. He starts begging me, “please no more” but this has made me decide that he needs a little more tormenting by mummy! I mount his diaper and start riding it, his cries in agony and frustration can be heard as his useless little cock is firmly crushed into the diaper padding by the pressure of my grinding. With each movement I can feel it shrinking, smaller and smaller until I am happy it is crushed and out of sight! He lays on the bed after I have finished today’s torment, weeping at the thought of his new life - fully regressed and diapered.
