Make your A-hole swell as powerful suction increases circulation. Anal engorgement combines with penetration in this unique pumping accessory. Just stuff your booty hole with the flexible silicone beads, 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 4 smooth bulbs of the anal beads will add additional stimulation as you increase the size and sensitivity of your hole, but they can also be removed from the cylinder. Both materials are non-porous, durable, and sanitize thoroughly with mild soap or toy cleaner. Avoid use with silicone lubricants.
