CBT: Toilet Bowl Brush
» Pervertibles / DIY
A suggestion left as a comment on Down On My Knees:
While you are down at Home Depot maybe pickup one of those circular wire and bristle-type toilet-bowl brushes. The wire can be bent by hand to accomodate any size or provide any amount of tension. A new one will at still be clean and fairly sanitary. And the experience of hundreds of strong bristles being forced over your cock might resolve your search for a bristle device.
