Name calling/dirty talk is great. It's even better if you can find some buttons to push that are personal, and incorporating that instead of just staying with the generic "fuck me slut" type of thing...talking can be such a great addition to sex.
Examples that have really worked for us
-suck it like the nuns taught you in catholic school, whore
-you little slut, getting wet just from sucking cock
-fuck me like you mean it, bitch
-c'mon, tuff guy, I told you to fuck me hard
-you filthy fuckin' pervert, put your tongue back in my ass now
-spank me, daddy, i'm so bad, spank me harder
-you pervert, your cocks hard just from thinking about eating my pussy
