It worked and it was wonderful if jacking off at the same time. It did as it was intended to be used for. I shoved it in my ass and turned it on high and I j/o and I came. I could sleep with it in. It was worth the money. I was hoping that it would be smooth and seamless I had to put a condom on it to make it more smooth other then that very relaxing. I could sleep with it in but it does get warm after about 15 minutes.
