Tenga Egg Crater, twist & squeeze
Tenga Egg Crater. The rumbling sensations of these crown-like details collide against your shaft for a tremulous exhilaration. The indented surfaces of the cratered nubs offer adherence from all angles, and their concave shape provides an optimal surface to entangle lubrication.
Always use a good quality lubricant with your sex toy and clean well before and after use.
