Well my friend, what you're looking for is RARE.
From my OWN experience:
In terms of girls who RESPOND to dirty talk I can recommend Shanti and Jayda at the BChain and to a lesser degree, Tamara @ BChain and MYA @ SRM.
IE> you talk to THEM.
Girls like Asha, Athena, Halle, MYA @ A & R, Monica @ Utopia aren't really into it. One MPA in particular got quite embarassed so I stopped.
If you're hoping for an Indian MPA who'll INSTIGATE dirty talk, the only Indian MPA I've been with who's good is TIA @ Allure. IMO Tia's very attractive but unfortunately VERY restrictive... that's the downside.
Lastly, keep in mind that dirty talk can fall under YMMV.
Generally I've tried this a few sessions after building trust so the MPA knew I was only dirty talking and not EXPECTING certain things
If it's a first session I'd suggest telling the MPA UP FRONT you like dirty talk.
