Porn sites with a theme piss me off, too. Usually it's the same fucking guy in every fucking video doing the same routine to a different girl every week.
Massage18? Girls Do Porn? I'm looking at you.
Massage18: Girl walks into room with a wide angle lens fully clothed and undresses. Lies face down on the table, puts a towel over her. Soft-spoken guy walks in and starts oiling the fuck out of her. Back of the neck, down to the back, "do you mind if I get rid of this towel 45 seconds into the massage?", "oh no I don't mind, I'm really slutty ha!", he's at the butt, uh oh, better start back down at the feet, move up to the butt again, getting frisky! Now he starts to move his oiled-beyond-all-fuck hands inside her vagina and she's always super into it. Now it's time to flip her over, oil the shit out of her tits and go behind her so he can hover his dick over her face and massage her again. Moves over to her right side away from the camera, spreads her legs, and takes her hand puts it on his dick, "is that okay?", "mm yeah I love penis", she pulls out his dick and starts to roll over to suck it, but no no no! he says, pushes her back into spread eagle so we can see her vagina again, then she does this odd side-blowjob for a while. from here on the order can it can vary, but it's going to include missionary, doggystyle (usually wheelbarrow style), and something that shows off how strong he is, maybe by lifting her up. cumshot, boom.
GirlsDoPorn: Girl sitting on a hotel bed with the same bed sheets and yellow wallpaper. "okay we have Yolanda here, tell us your fucking life's story", "omg you're interested in me? ok well I love swimming and-", "no like when did you last suck a dick and how many dudes have you fucked and do you like threesome with girls?", "oh ya all that stuff lol", then she babbles on and on and omg, skip to the 5 minute mark please, "ready to get started?", "absolutely I love dicks". the same face-less, hair-less, slim body of a man comes out in jeans and no shirt, she is fully clothed and starts to unzip his pants and you've got a 50/50 shot on how well she can suck dick. scratch that, she absolutely cannot suck dick, I don't blame her, that dude's dick looks above average. wow nevermind, she really can't even take more than like an inch or two, this is just sad. he's piledriving her face and she's gagging, please just go easy on her. "no you can't hold my dick, put your hands at your side, I'm going to awkwardly grab your tits and then slap them around with my penis". it's been like 2 and a half mins, she's takes her shirt or dress off, sniffling because her sinuses are getting clogged from not breathing. suck some more dick, you start to notice things out of boredom like how the lighting makes everyone look more tan and is this a set or do they rent out the same hotel room, are the owners cool with it? etc, etc. finally the guy behind the camera is like "great, wanna get fucked now?" and she's like "yes please, that sounds so much easier." if he's feeling nice he asks her for her favorite position (spoiler - it's doggy), but if not then they go missionary. this is followed by cowgirl, coupled with a shot from the headboard, then woah-ho! reverse cowgirl, so crazy. more dick sucking right in the middle of the fucking video every time, it's never any better, ever. doggy style is next, maybe some sideways fucking, maybe lifts her legs up so she's at a right angle, then some harder missionary again, tons of tit squeezing. blowjob fucking again to finish it off. she licks the balls here usually. always a disappointing cumshot, it's never a lot and she's usually sitting there looking stupid for a minute while he tries to finish. sometimes a shower afterwards.
I'm fucking dizzy from typing all this, but I don't get why people like to watch a video if you know EXACTLY what's going to go down and the only difference is it's a new set of tits, ass, and face. Maybe I'm jaded, but I find no appeal in a pattern. I could easily do more of these (BangBus is another that comes to mind). Recently all that's doing it for me is some amateur stuff and sometimes some lesbian stuff since they really need to get creative with no penis in the mix.
