bound to vibrator
post #2770036 post #4079150 post #2875124
A character has a vibrator bound to their body (such as attached to their thigh or belly with rope or tape, or incorporated as part of a belt or harness) in such a way that they are inescapably stimulated by the vibrator. Frequently incorporated along with other bondage or restraints to further restrict their ability to either move away from or remove the device.
If the vibrator is not directly bound to the character, but the character is held in place against the vibrator, simply use fixed vibrator instead.
