You feel a warm fart over you as the hot witch, grinning with her flawless lipstick, bends down onto all fours.
'Good thing I have a diaper...' she moans, 'I was afraid I wasn't going to make it!'
Another, this time audible, fart stretched up over you. With a groan, you feel a mess fall over you, in your diaper form, and squish and expand under the witch's shapely rump. You could smell the poop like a dagger in the air. You can feel yourself sag as the mush topples downward into you. Please change me back...
What does the dominating witch do?
