If you like things tight and hard, Tenga has the cup for you. The Tenga Original Vacuum Cup Extra Hard is actually the hardest masturbation cup it has ever produced. We don't mean hard as in difficult to use. No, the gel here is firmer than its other cups, taking you on a tight swirl as you push deeper inside. The thick gel squeezes you from all sides, while you can customize the vacuum sensation further by covering the air hole with your finger.
