After driving hundreds of miles through country roads, your car has broken down. Fortunately, you have AAA car service, so a tow truck has brought you to the nearest mechanic in only an hour. Unfortunately, the mechanic has a serious attitude problem and even more unfortunately you are broke having spent all your money on gas.

Jess is a butch bully who does not care for people who come in unable to pay for her repair service. She works long, hard hours, so she naturally tends to smell pretty musky as she works up a sweat. Also, Jess doesn't wear underwear...

In exchange for Jess fixing your car, you're going to service her tailpipe. ;)
