A woman who caught her husband having sex in a car with her twin sister got her revenge when she left the cheating pair nude in a parking lot.

Ting Su, 29, was suspicious that her husband Cheng was fooling around so she followed him one day and caught him naked in a car parked at a shopping mall in China with her equally naked twin sister.

Su confronted the frisky duo, who thought it would be a good idea to bolt buck-naked from the car.

A quick-thinking and vengeful Su jumped behind the wheel of the love machine, leaving her husband and sister naked in the parking lot.

The commotion caught the attention of onlookers who were quick to flood social media with images of the mortified mistress and Cheng chasing the car as his jilted wife drove away.
