Got curious by the comments, so decided to read it. Here's my honest opinion:
It's averagely funny. It acts as more a parody of hentai than anything else. I don't get why so many people are commenting that this is terrible trash, it's definitely not that bad. It's moderately ecchi, nothing too explicit.
Why is she still trying to get the D from an orc that doesn't want to give up the D. Just go find another one? BUT NOPE! It got to be the D from this Orc child she is raising(?). I know there is a word for this in Japanese but I don't remember its name.
