This is my first double dong. Before using, I passed to the washing machine. The smell is strong enough. At first glance, it is not very big but once you use it, we finally discovered its size. It is flexible enough to be used for a double penetration solo although 4 cm in diameter are felt at the anal. I also used a couple with girlfriend :). He holds up and is rigid enough for penetration face to face. In short a good buy that reveals even more intense sensations.
