Enjoy a completely new experience. The innovative TENSEK 4 joins the JAMYJOB range of masturbators and features a unique, all-black design that’s easy to grip. Every part of the TENSEK 4 consists of numerous suction lines and caressing nubs that will pamper you every time you insert and withdraw your best asset. The flexible walls mould to your penis and further enhance the sensual sensations. The TENSEK 4 features a comfortable grip to facilitate movement during masturbation. As always, JAMYJOB aims to put the power in your hands and deliver perfect stimulation. To achieve an intense orgasm, we strongly recommend using water-based lubricants. We recommend the AQUA or WATERFEEL brands. How do you clean the TENSEK masturbator? The soft TPE ULTRASKYN material makes the masturbator easy to clean. Warm water and mild soap are sufficient for surface cleaning. Then moisten the sleeve with a disinfectant such as Waterfeel Spray Disinfectant!
