Being the sometimes sadistic, but always perverted, male person that I am, I have become a big fan of the Lush. This is a g spot vibrator that is inserted into the lady and controlled remotely with an app on your phone. It has a number of patterns and variable strength and duration. Great to use on the so/gf/slut of the evening out at a bar having drinks (gently just to cause some squirming), at a swing club (to get her motor really going), tied up or suspended (can induce true insanity), or to encourage that bbbj into becoming a bbdtcimnqns.
