Strange question. What are the best videos that she had for dirty talk? Did she ever use any nasty words like tits, pussy, cock?
I was busy and I was hoping someone else would respond! You are a bunch of lazy bastards!
So, I will also be lazy and just cover what has been previously discussed rather than spending a lot of time on this question.
As we said on the previous page, HD X Red (release date 2-26-2014) has some pretty good dirty talk. At 14:40 she says "I wish your dick was inside me." This video also has a lot of pussy exposure and a clearly horny Christina. Run, don't walk, to this video if you have not watched or rewatched this video recently.
Another very entertaining video, released a couple of days later on 2-28-2014, is HD X Yellow. If you want to see a long clear view of Christina fucking herself from behind, with her asshole clearly exposed, then you need to watch this video. In HD X Yellow, she says the following:
11:55
You like it when I fuck the dildo? ... I wish I could fuck you.
16:25
Mmmmm...my pussy tastes go good. ... You want to taste my pussy?
The second quote comes after she has been hammering her pussy with the dildo for a very long time and then sucks and licks it clean.
These two videos are very similar in that Christina appears horny and almost possessed. Perhaps she is under the influence of something or doing something with hormones for her fertility. Either way, they were probably recorded within hours or at most days of each other because the style is similar and her state of mind is similar.
