Lurks What I really miss the most regarding closeups is the following:
1) Lack of gaping
Girls are shown spreading their pussy lips to show some pink, but I just don't see the deep, internal shots of the vaginal ripples. I'm not talking about using a speculum, either. Just have the girl use both hands, push her fingers in deep and pull the walls apart. The advantage is that it helps the brain envisage what our dicks might feel like when we insert them in her. I mean, that is the essence of porn -- at least to me, anyway. And if the directors could just cut the scene beforehand, hand the girl a Hitachi wand and let her play with herself for a few minutes, she would almost certainly be able to work up some thick wads of cream inside -- and perhaps even start dripping out the hole. There is really no need to be bashful about showing deep gaping.
btw: I am really big on dripping pussies, but one of the byproducts of that is when her cum soaks her panty. I noticed that some scenes have the girl present the panty up to the camera to smell it, but it is done too quickly and I just don't see the wet spot (if it is even there), so the effect is lost. Another scene had the girl display a panty that looked like someone poured a glass of water on it, making such a large area of wetness that I just felt I was lied to. It has to be done right.
2) Clit closeups
Only 40% of girls are able to orgasm by penetration alone. The rest do it with clit stimulation. Essentially, the clit and G-spot are the two most erotic zones on a girl (they are part of the same nerve network) -- and yet, the clit is too often overlooked. In my opinion, a special emphasis should be placed in EVERY scene where a girl SLOWLY pulls back her clit hood to expose her love button. Those things can swell up in a big way on some girls when they are excited, so to overlook that is a mistake. Follow up the exposed clit with the girl twirling it, flicking it, and pressing down on it -- all with careful close-ups and all the while cutting out briefly to show her face whenever possible as the electricity shoots up her body, and I think it could add a lot to foreplay. It would also help the girl get more warmed-up for when she does get impaled with a cock later in the scene -- possibly even assisting her have a real orgasm rather than just a (commonly) faked one. Anything to help with the real orgasms should be a goal of any scene, I think. It is hard for girls to fake those little convulsions when they orgasm and those convulsions are great at helping me blow a load.
