If you have a taste of evil fetish, this will appeal to you.
- Both are the BEST Hentai I've seen with bestiality. In Kowaku, it's sex with a Bull. In Haitoku, it's sex with a Dog.
- Both Hentai has a girl trapped into a situation of submission, but in Kowaku, there's a guy trying to save the girl.
- Both Hentai has bondage. Difference is Kowaku has some torture, while Haitoku has some scat.
