Satisfy your desire for back-door adventures with the 4.25" Medium Triple Ripple Butt Plug. This thick plug has a unique shape that starts off petite at the head then gradually widens and tapers into 3 big bumps for tons of sensation during insertion and removal. The wide base makes it safe, and compatible with an O-ring type harness. As with any ass toy, you'll want to use lots of lube. Water-based formulas works best with our rubber material. It is made from body-safe phthalate-free PVC, and it's Proudly Made in America.
