Ferrid's manga / #ecchi(31)

Kinda beastiality. Like a harem except the guy is a cat. Ch 23

Basically isekai hentai without the dick penetration. They do get penetrated by tentacles and fingers tho so.. Ch 27

The summary is a bit misleading. It's more like a perverts guide to another world. A guy gets isekaied to another world where he has game like abilities that make him a cheat but instead of being a hero he decides to buy sex slaves. Half the manga is him taking a bath with his sex slave. Ch 31

Basically every japanese mans wet dream when they die and get reincarnated into another world. Ch 11

Transported to a world where there are no men! Women go into heat when they are touched by a man and won't live past 20 unless they have sex due to a curse placed by the "Jealousy God". Also, alien gang rape poison sex
