From the front and from the back - enjoy two different sensual sensations.
A cup with two holes 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"
