Suggestions? Ok, I have a couple.
There are some things that the girls do consistently every single time that they could change up periodically to add some variety.
Like always floating their legs way up in the air during missionary. Holding their legs back with their arms. Does every single girl have to do that every single time? If she needs the back support, you could put some pillows under her. This is not natural missionary, and it has a way of breaking immersion, because it reminds you that she is having to do that because of a camera angle etc.
Or giggling at the end of their sentences, when no one told a joke. That's kind of off putting, and even creepy sometimes. Is she about to pull a knife on me or...
Things like the unnecessary giggling could be due to try-hard acting. Where they look like they are merely performing a show; trying to be sexy instead of just being themselves, being sexy. Instead of her enjoying getting pounded by the stud, they are strong-arming the scene to be sexual instead of them naturally being sexual. So it's even hard to tell if they are faking their orgasms half the time.
Anytime the girl looks upwards or to the side at the camera crew, that utterly breaks the fourth wall, ruining immersion. That is 100% a no-no in my opinion. I would even cut those parts out of the videos if it were me.
As for a scene suggestion:
Lots of girls start out with a really pretty outfit, and it's fun to see them have the initial conversation, wearing their outfit. Then they always get buck naked before the action starts. Is this always necessary?
Once in a while could the guy just press her against a wall and get it in with her clothes mostly on (The rare stand-up missionary pov scenes are great). She can always get naked later; there's always more time to do other stuff.
The same studios always shoot their videos in the same rooms. Could they not mix it up by shooting in other places? I swear 9/10 of all videos are in a living room or bedroom of some huge mansion. Ok, but is that the only places people have sex? If this is an immersive role playing pov experience, are you saying only the super rich have great sex, or are worthy of sex or something? If a good chunk of this customer base is here partly because they have varying degrees of struggle with women in real life, could you think about not proliferating this issue when they are here attempting to escape it; not be reminded of it? Sure, it's fun to pretend to be a rich guy, but that isn't what this is for. Not only is it a reminder of some of the cold hard facts of life, it's tough to not be thinking of the actresses in the (mansion) videos as gold diggers. Where, if I'm the man in the video, and this is obviously my mansion, then "Does she only likes me for my money? Is she sleeping with me just as an ambition?" (The try-hard acting can aggravate this problem too). So shooting videos in settings that only the super rich can afford, could psychologically work against the viewer, who is trying to enjoy the act; trying to forget about their own personal problems. This is entertainment after all. So shooting videos in modest places once in a while wouldn't hurt, in my opinion. Just something to think about.
