This sleeve is covered with bumps, cleverly curved for G-spot stimulation. At the base of the sleeve is an opening to slip a vibrator in to and, guess what, included is a waterproof, mini vibe. The people at Pipedream are nice enough to hook it up with a battery, lube and toy cleaner, too. The sleeve is made of clear silicone and will stretch to fit any size member. This toy will give that special lady ultimate pleasure, it has bumps, a G-spot curve and a waterproof vibrator. Stock in your couples section and watch the girls get excited.
