A sign of our times: when a girl sets her cellphone on vibrate and tucks it in her crotch wile she drive/sits at work/whatever and is expecting a call at any moment. When the phone 'rings,' the girl tends to shuffle a bit in her seat.
I was at a stoplight and saw this girl in the car next to me looking like she was cumming. Then she pulled a phone from between her legs. It was a pink shuffle.
