I've seen a few Mia Rose scenes. Whenever she is with a big guy she really gets off and doesn't stop cumming. E.g. her scenes with Chris Charming, Manuel Ferrera, Erik Everhard and Mark Ashley.

I know that most female orgasms in porn are fake, but her reactions seem pretty genuine to me, and doesn't have any annoying theatrics or screaming. And I like watching girls who get off on being fucked hard and deep.
