What do you do when your twin is having sex with your husband?
Scorned wife Ting Su learned her husband, Cheng, was cheating on her so decided to punish him.
Following a mobile phone tracker, Ting Su found her 30-year-old partner naked in a parked car with her own twin.
Realising they had been caught in the act, the pair hopped out of the vehicle completely starkers.
Seeing her opportunity, Ting Su jumped in and drove off, leaving her sister and unfaithful hubby embarrassed and without dignity.
Eyewitness You Meng said: "He was banging his fist on the window and shouting at her, and she just wasn’t playing ball."
Ting revealed the two had been having an affair since before the birth of her own twins.
She has since filed for divorce.
