Get the party started early.

Sally can't help herself. The drive to the mall made her shift in her seat as she worked the clutch and the stick shift and the dress worked its way up over her hips and her thong snaked its way deeper and deeper between her pussy lips. Soon enough, she was double clutching and rocking her hips, forcing the thin veil of material even deeper into the cleft of her pussy and grinding her clit against the material.

By the time Sally actually arrived at the mall she was panting with need of release. She considered everything in the car; she had a micro-vibe on her key chain for just such an occasion, she had her fingers (though her pussy would have swallowed her fist by now), and as she slid the car into a parking spot she found herself stroking the giant knob on the gear shift. She looked at it carefully as she put the car in neutral and hit the parking brake.

It was an eight-ball that had been drilled tapped so it would screw onto the gear shift. She licked her lips as she considered the options; she knew her vibe would get her off, she knew her fingers would do the trick, but that ball would stretch her sooooo good...

...but then, who knows what else was in the car...probably some water bottles, maybe an empty beer bottle...
