Dirty talking tips

My fiancé has gone to stay with his mum for Easter and is coming back tomorrow, I didn't go because I had to spend Easter with mine so we decided I would be seeing his family this weekend and him mine the week after 😂 anyway were texting right now and things are getting quite heated.. I want him to talk dirty to me but how do I get him to start? Or any sly things I could say 😉
