Jump in the car to go shopping

Lilly figures where better to go then shopping on her birthday. About an hour away is a trendy shopping plaza with plenty of people to show off to. Lilly jumps into her convertible and shifts into reverse. Her road is pretty rocky and all the vibrations are starting to get Lilly horny again. 'Man I'm just so horny today, maybe after this ride I'll find someone else to help me get the job done.' Lilly thinks 'But for now I need something as soon as possible I can't stand the tease of these vibrations much longer.'

Lilly looks around her car and sees a few options--

Hairbrush,

Cellphone w/ vibrate app,

Glass Soda bottle,

Flashlight
