We've talked in the past about the science of pornography. How porn has changed the way that men view sex and pleasure. In the interest of science, I have a little experiment for you. You're going to grab a hitatchi and situate it firmly under the head of your cock and turn it all the way up. Then, for the next 10 minutes, you're going to watch porn. I've interlaced several videos I think will be particularly exciting into this one. We're going to see how long you last. Will you cum right away? Can you hold out? We're going to test just how conditioned your brain is to cumming for porn.
