Makai Kishi Ingrid

Taimanin Asagi is a spinoff of Dark Knight Ingrid. Same producer Pixy. 

Both have taboo group sex scenes. Both have pretty character designs. Both have very good animation scenes. Both are erotic.  

These two hentai OVAs have evil demonic monsters that are trying to wipe out humanity. They both have tentacle rape, blood, gore and extreme graphic nudity. Not to mention, they both try to focus more on story and characters than sex.  

Similarity : Both anime tell story about a groups of demon hunter A organization with a mission to protect human from demon Different : + No Lesbian Scene (Makai Kishi Ingrid) + No Mass Rape Scene (Guren) 

Those it feel good???( is what you will hear the most) Rape/ torture Tentacles Boy and girl fall in love Great sex scenes( kinda if you like it) Great ending song I thought the art and effects were awesome. VA's did so good
