Desperate girl smoke to hold her pee

After a long trip in the car, on a hot day, this girl had a lot of juice and now her bladder is pretty full. She smokes and takes off her panties in the car, trying to release some of the pressure on her bladder. She is so desperate she can't hold it much longer. She doesn't care if she is seen by people passing by and she can only keep her pee by smoking.
