Isekai Meikyuu de Harem o
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

Why do perfectly good isekais have to turn into harems!?!? Also what is with the tentacle slime ability and the aphrodisiac slime ability that makes people into sex crazed slaves. That's still rape people!
