Watching "Double Penetrations Tryout 4" and beeing totally fascinated by this girl. Must have been really one of her first scenes ( until now only found 2 scenes in Adultdvdtalk, nothing on freeones and co ...) and she is so cute.
In the beginning she knows to suck one dick but the guys have to remind her several times that there are two dicks and that she can stroke that second dick while sucking the other. You can really see that she isn't that sure what to do with two dicks but the buys are really gentle and help her by just taking her hand softly to the second dick and then she slowly starts by herself stroking it. Kind of nice amateur/newbie style.
Then it comes to the fucking she seems pretty comfortable and perfectly knows to give a no hands blowjow while the other dick is in her pussy during doogy style.Later they change dicks and first to cowgirl and then to reverse cowgirl. In reverse cowgirl is so nice to watch her getting fucked balls deep. They then change again to doogy stlye and the anal treatment starts while the other dick is in her mouth. Some secondds after the dick entered her ass the cameara changes to her face and you can see how hard and unknown it is for her. After a few impacts the dick goes in for 2/3 of its lenght with some nice moanings of her and it seems she is on her limit. Then she's getting asked if he could go deeper she just says "mmm, mmm" (meaning "No"; she cann't speak because of the dick in her mouth...
). Directly after her answer is a cut. I think it's nice they left that deeper question and no answer in the movie it makes it much more natural. It goes on with her laying on her back on the bed and getting fucked in the ass. She is really concentrated in this part. She bites on her lips and clench her fist and then one guy says " You can say it hurts.", she laughs and says "It hurts". So she starts rubbing her pussy during assfucking and one boy says he would knew a better technique of giving her pleasure during assfucking... 
So they change again the position to cowgirl and after inserting the dick into the pussy he asks " Can I take your mind of your ass with fucking your pussy like this?" She answers just with a moaning in agreement. He: "But he still will fuck your ass!" She now only moans "Yeah!" and the DP starts. I think that's really a cool storyline and acting to introduce a girl to DP 
During the DP Carrie is for sure on her limits but she can handle it and seems (nearly) comfortable.
