Tom has got a girlfriend here name is destiney gardnerThat is not her name....nor was it ever!! Her name is Giovanna Falcone
You can call her by her name directly. If you mean how do you refer to her, there is no special term, just as you said it in the question. She's your girlfriend's sister.
if you mean she is his daughter, then it is your niece, if it is his girlfriend call her by her first name.
