Jeff is one big boy! He has a large length and large diameter, so there is plenty enough to go around. This dildo is made from super realistic UR3 material which mimics real skin. It is a little difficult to maintain, but it is worth it. On the bottom of the toy is a suction cup that sticks and holds to any level dry surface. Unfortunately, the suction cup does not work well in wet conditions, so using it in the shower will prove difficult. The shaft has a few raised veins, and the head isn't super pronounced. If you can take his girth, Jeff will definitely please you all night long.
