" I bought two vixens, one for me and one for a friend in another state. He hasn't had a chance to try it out yet but I have, and holy crap, it's incredible! Now, I've used larger things before as compared to the shaft thickness, but when the Vixen is comfortably in place and the knot gets inflated, it creates the most incredible, intense sensations I've ever felt. I mean tense-legged, room-spinning, uncontrollable-panting sensations. I'm not exaggerating here! It's the same for air or hot water inflation, too. I'm looking forward to the next time I get to use it. I haven't tried the Cinnalube yet, but it smells good enough to eat. Thanks! "
