I purchased a progasm jr & peridise set for having been a good boy 😎 and since I wanted something different as I have been having difficulty with the mgx, something with the ridges on the bottom, I will revisit this one at a later date. I got them yesterday and decided to try the jr first. I can only say, man what a pleasure tool. I was a little intimidated at first but it slid in so easily with that glass like surface and nestled in like it was molded just for me. Once on my back it just disappeared and the involuntarys started in earnest as I tried like hell to keep joined, This guy wanted out! really forced me to work for it. I have only had 1 orgasm with it so far and it was completely different from what I received from helix. Instead of getting hot my body went ice cold, like I was dropped into a freezer. Felt exhilarating.
I than moved onto the larger peridise, after sitting for several minutes again the involuntarys started and kept going for about 45 minutes. Got some interesting sensations. At one point the tip of my cock felt like it was getting zapped with electricity. once they stopped the only way to keep them going was about a 50% grip. I went on to try the smaller one. Once again they started and lasted about the same amount of time. I didn't get any orgasmic sensations but the muscles moving so fast was wild. I did notice that even though I has not having any involuntarys I could feel the muscles trying to get a grip this smaller tool, quite an interesting feeling.
