First off, I really wanted to give this hentai a Very Good rating; but I could not.
Don't get me wrong, this is a decent hentai. I personal felt that they could have done so much more for a monster rape hentai.
Princess Knight Catue falls under the "Bikini Knight" genre of hentai
The premise of this one is this: Princess Knight Catue, the "heroine" in this story comes home to find her kingdom in ruin, buy a demon-lord. Her loved ones: Mother, lover, and citizens are held captive and in order for her to free then, she must endure several days of humiliating sexual torture.
the first day she must orally serve her elite guard, and have sex with a large pig-monster in front of her lover. Meanwhile the demon-lord sexual tortures Catue's mother, even as far as to make her sleep with Catue's lover and her own daughter. In the end it was all for nothing, pretty much the same ending for some monster hentai it seems. . Also I should mention it turns out Catue and her people are descendants of Dragons.
The plot was not at all my problem with giving this hentai a better rating. Sadly it was more of the character design and the sex scenes.
For one, all the monsters were well-endowed to the point where it was just laughable, and straight up not enticing. It seems the character designers were in some sort of "who could draw the most ridiculously big dick" contest. I say that one went to whoever decided to give the demon-lord's penis a "second-form" (Watch the last episode) And really I could not tell if he was a demon-lord, or just some demonic Chip N Dale dancer who likes to be evil on the side.
I will say Catue's mother's breasts were a little too big, but that didn't bother me as much; I like the scene where she pleased the demon-lord. Speaking of sex scenes, that is where it was really lacking I felt. They could have done more. More gang-bang scenes with Catue, and her mother too; that didn't involve catue just being in a harness. Sure we see her in a gang-bang somewhat in the end, but it was just quick shots. Plus don't forget that the monsters were really just over-endowed.
