Nice models, but somehow the whole 'threesome' idea doesn't really come across because she looks utterly uninterested in it occuring. But I don't know the character, maybe that's her personality - to be unemotional or uninterested in things.
This really needs to be an animated GIF, not a video. 3-7 second loops just look plain lazy when put into video form, especially when there's no sound whatsoever. I'm sorry. I just can't give a good score to something this lazily done. Looping animations requires almost no effort, and it doesn't even look like it took more than 30 minutes to make this.
If you're gonna do a good loop, then please try to find some good loops as a reference to see what you can add to them. There is so much you can do with a short 30 second loop, but you have to be willing to put the time into it.
I'm not trying to be an asshole. I just see so many of these lazy loops that I can't give them "good" scores anymore. About the only thing this has going for it is the animation more or less looks good. I can't review anything else about it really because there's nothing to review.
