Clit pumps may seem odd at first but in fact provide a whole new sensation to the pussy lips. Just like the penis, when pumped up, the lips of the pussy become more sensitive because they are engorged with blood. It might take a couple of tries to get used to the feeling but once you do you'll realize that having your pussy lips pumped to the fullest is incredibly erotic and a huge turn on. Keep in mind that once you pump your pussy it will remain ultra sensitive until the blood dissipates. That said it's a good idea to choose a day that you can lounge around the house so you have amazing sex many times over and allow your pussy lips to deflate.
