Fighting with your partner over who gets to go first? Can't decide whether you like a throbbing pulse or a rapid buzz? The Dynamic Duo swoops in and saves the day: separate variable-speed control dials mean you can tickle two erogenous zones at the same time, thrill to two different levels of sensation, or get off at the same time as your partner. And separate jacks mean the 37-1/2" cords stretch further, making it even easier to hit just the right spots.
