The outer structure features large rolls for intense stimulation with every thrust. The testicle strap helps keep the sleeve in place, and the design with the open end allows you to feel more from your partner. The walls are extra thick for a noticeable increase in girth, with separate cutouts for the penis and testicles for comfort, stimulation, and safety. The phthalate-free material is body-safe, easy to clean, and is firm yet smooth enough for easy insertion while remaining flexible.
