Oh there are just so many out there to choose from lol. The main one that I have been loving so far is my Hitachi. I never had one before doing webcam. One day I was watching a model doing a show and she pulls out a medium size machine. So when she started to play with it she put it on her clit. seconds later she starts cumming like crazy. That's when I thought "I need to get this shit like yesterday!" I purchased one online and when it came in the mail I cleaned it and used it instantly! The vibration in that machince is intense. Best for my clit stimulation. I can cum over and over and over and this machine doesn't make it stop (which I love) It has so many levels of intense vibration. I like the 5th level lol!
