A cup with two holes that allows you to enjoy different types of sensual sensations - the Bitter Side and the Sweet Side.
The Bitter Side firmly tightens while the Sweet Side gently clings to your penis. Normal use is one side at a time. But, using both sides simultaneously transports you to the virtual world of a threesome.
All TENGAs have lubrication inside. The lubrication consists of: purified water, glycerin, sodium polyacrylate, phenoxy ethanol, and paraben (allergy tested in Japan).
