This one is a favourite after a massage feels great to tease with on low speed and work up to a higher speed as you get closer to that sweet spot always works and gives a very strong orgasm that just drains her in a good way, she like using it as much as I do, if she uses it, while I am there I have a hard time to hear it, it is very discreet and batteries last a long time if you use good quality ones ( a month or a bit longer ) the cheap batteries are ok in a pinch but drain pretty fast ( a week at most) and we use it at least five times a week, so use good batteries and you will be please with the results.
