The countless hexagonal protrusions with a sense of edge stimulate every part of the body from all directions. In addition to up and down strokes, you can also experience free pleasure by rubbing and stroking.
Blow up that booty hole with a pumping accessory that penetrates you with a smooth, bulbed rod. Just insert with any lubricant of your choosing, attach your compatible hose and pump, and begin squeezing to build pressure in the cylinder. Your anus will be sucked in, puckering out like a blooming rosebud! The ribbed textures that continue down the length of the rod will add additional stimulation as you increase the size and sensitivity of your butthole.
