We've had our share of masturbation sleeves over the years and tried quite a few different styles ranging from realistic pussies, asses, and mouths. Each of them is a bit different, just like in real life. That being said, the Hot Dream is something different from the others and marks the first time we've had the pleasure of so many features in one product. The vibration option has been done before, but the warming and sound choices are something new. I love that my fake pussy is so warm and inviting and that it tells me how much it loves being fucked. It didn't take long for me to learn to use extra lube and fill the sleeve with it before warming it up. I've also learned that it fits nicely between the mattresses, and I can fuck hands-free.
Another thing I discovered is that there is a small hole on the case that, when covered, provides more resistance/suction during stroking. Covering this hole with a finger prevents air from exchanging between the sleeve and the case. It nicely increases sensations while decreasing the noticeable pussy fart sounds during use.
Besides the solo playtime, my wife has also pumped the Hot Dream on my cock and combined that play with some anal toys on me. The end result is always a satisfying orgasm that doesn't take much time to achieve.
