Spartacus Double Ring is an explosive fusion of four concepts (double ring with vibrating sheath and clitoris stimulator) in an irresistible, ergonomic pleasure-giving object. Conceived to maximize your performance and intensify your excitement, its innovative design features a horizontal vibrating ball fitted to the lower ring, designed to produce irresistible vibrations on your testicles. During penetration the pleasure is doubled by the thickness of the silicone that considerably increases the diameter of the penis. The vertical vibrating ball placed on the upper protrusion of the sheath is designed to spread the vibrations along the entire penis, stimulating the caress of the clitoris intensely, from top to bottom by suction. Spartacus is made from top medical quality silicone with a velvet feel and sufficient flexibility to adapt to any type of body. The double ring vigorously stimulates the testicles while enabling you to maintain an erection for a longer period of time.
