Vibrating toys can indulge, they can manage to give tantalizing pleasure or become almost unbearable.
There are hardly not set boundaries to your fantasy when anally placed vibrators can be inflated or activated via remote control while out for a walk.
The scope is wide, depending on the area of application and strength as well as personal state of mind. The best example is the Wicked Wand Silicone: for some the only vibrator to be taken seriously, for others an instrument whose mere sight will cause the blood to curdle.
One person's meat is the other's poison!
