The Butterfly Effect Dual Vibrator

The Butterfly Effect is a really complicated scientific theory that (to way over-simplify) basically means that a huge event like a tornado can be set off by the tiniest of events - like an air disturbance caused by the flapping of a butterfly's wings. Physics is not our forte, but we do know that a huge orgasmic event could be set off by Evolved's Butterfly Effect Dual Vibrator!
