This Tenga Onacup masturbator easily passes for a deodorant or other grooming product. Nobody would suspect it’s actually one of the most popular male masturbators on the market. In this Double Hole Onacup, you get two different sensational options. On one side, the ‘Sweet Side’ is soft and lightly textured for a gentle thrust and easy insertion. On the other, the ‘Bitter Side’ has a vigorous entry and strong constriction, with increasing sensation as you thrust. The two sides have separate sleeves to keep them completely hygienic. This innovative masturbator is designed to be used just twice (once in each sleeve), but if you use a condom you should be able to get a couple of uses out of each side. It’s pre-lubed for greater comfort, and well-sized to hold in the hand as you thrust.
