It looks very unpleasant - a well-pumped guy is trying his best, and the lady's face is covered with a strange grimace. In general it is not clear - whether she enjoys sex or performs an unpleasant duty! And the body of the lady is not particularly that glitters, and her breasts and nothing at all!
Looks good - anal tight and not ripped, labia tightly closed and not sagging. Rather fresh woman, not really developed sexually, there is a chance for a man with a small size organ to feel the dense coverage of the penis. That's what I appreciate about women, I don't like it when my dick falls into a woman with almost no resistance. It makes sex so much less enjoyable.
