The girls at Big-Tit Tune Up are hired not just for their skill at repairing the latest autos. They also have big tits, hot asses, fill out a pair of tight overalls like no one else can and they are highly trained in fixing your wagon. You can trust your car to the girl who busts a bra. The BTTU Girls don't like annoying customers but sometimes there's no avoiding them. In this case, Gianna finds herself stuck with an irritating dude who she would like to get rid of but business is business. Gianna is used to dealing with assholes. She has her own special way of servicing them. Johnny Rod likes to bring his ride to BTTU because what he wants, he can't get from a 50 year-old overweight mechanic. When a guy can get a complete overhaul and boob-lube job from a babe like Gianna, why go down the street to save a small amount of cash? Not only that, but the girls at BTTU include a free tongue bath with every visit. This company should have a chain across North America.
