Sara Blasse is accused of filing a false police report.
The 23-year-old initially told police she got lost while driving in Chesilhurst on Sunday and asked a man for directions.
Police say the 5-foot-4, 300-pound woman said the man pulled her out of the car at gunpoint and threw her to the ground.
Officiers say the car, which is owned by Blasse's father, crashed into a tree and was set on fire.
Police say Blasse later admitted the crash occurred while she was giving oral sex to a man she had just picked up.
She refused to identify the man, who was driving.
