Combining Nasstoy's powerful 7 inch Whoppers vibe with a user friendly universal harness, this set is a winner for fans of role-reversal and for girl-on-girl play. The harness itself comes fully assembled, you'll just need to step in and adjust the straps for a perfect fit- the wide, comfortable straps and a soft, leather front-piece and back band keep the vibe secure. 2 metal O-rings are included, they snap onto the front easily once looped around the base of your chosen toy- most dildos and vibes with a base will be compatible. Long and slim, the shaft of the included Real Skin vibe is straight and precise, seeking out sensitive inner sweet spots like the g and prostate, depending on you you choose to enjoy it- regardless, the supple surface with its firm precise core is sure to please. Three speeds are yours for the choosing, they're controlled easily with a simple slider-dial remote. Out of the harness, an incredibly strong suction cup at the base lets you attach the Whopper to any number of smooth, flat surfaces for hands-free use. Use a great quality water or silicone based lube with this toy, it'll keep things slick and enjoyable, while protecting the material. Takes 3 AA batteries (sold separately). Not recommended for use in water. Harness fits most.
