sugar coating the snake 

When a woman or man hides their true identity and makes themselves look sweet to lure in prey. A disguise that hides their snake like soul that has viperous natures but they need to look sweet to get close to someone to take advantage of them.

A woman who is a PHD student who wants a baby and then lures in a nice man to have sex with her. After she is impregnated, she then disposes of him and takes him to court for the money. The man is left wondering what the heck happened while she is taking him to the cleaners. But when she needs something she lures him back in with sweetness then bits into his jugular when he is at his weakest.

From real life:
she's changed a lot in the last month. Seems sweet again
but perhaps it is just sugar coating the snake
