Sheer ecstasy was the look she gave.
I bought the Motorbunny Buck for my wife. She couldn't believe how much I spent on it. But then, she got on and I turned it on. Then the look on her face turned me on. 1 through 6ish, she does good and can hang with no problems. 7 through 9, she's about to explode. 10, she has exploded. 11, paralyzed her and she begged me to turn it of. Yep, that's how it went... Three times within a 15 minute period. She wasn't worth a damn for the rest of the night. Money well spent.
