I used KIN 2. Mei's hand did not come out right. What do you think happened?

Prompt

A woman lies on her back on a white bedspread in a college dorm room.
Her legs are raised and spread open.
One man kneels between her thighs penetrating her.
Two other nude men stand close on either side of her.
One standing man grips her raised leg.
Books sit on a desk behind them.
Cool white light fills the room.
String lights hang in the background.
The camera faces the action at eye level.
