The Premium Silicone Dildo is a realistic dildo with a Dual Density Shaft. This means it has a firm inner core that is filled with patented Silexpan material, and a soft, lifelike silicone outside. This adds to the experience when using this toy: penetration will feel like it’s the real thing! The glans, scrotum and veins also contribute to this experience. The dildo has a suction cup base, so that it will stick firmly to any smooth surface, very convenient during solo play. Another great feature of the Premium Silicone Dildo is that is has Thermo Reactive properties. The dildo will become softer when it is heated in water or a microwave, and harder when it is cooled in water or the fridge. An advanced dildo for advanced sexual pleasure!
