"Never ever speak like a slut again". Am I right to say this to my girlfriend in this situation?

Anonymous
For fun, to make me jealous, she told "I've thought about sleeping with other guys". I got shocked and she said that again !! "I've thought about doing everything with other guys".

This happened 2 days ago and i punched her shoulder and she apologized. But she still says that was fun and I'm getting angry. Am I right to say "Never ever talk like slut again! If you does, our relationship will end".

What do you think?
