Been a long time since I updated my list but I was kinda busy procrastinating and sht and now that I have time maybe I should continue this story dump. Anyways....

How about a story which starts out a younger brother who gets transported into a world where he needs to defeat a demon king?

He who have knowledge of the game his older brother was playing, was excited that he gets to be a hero and save the world and even beat monsters up, not knowing that the game was a H game. 

Que in Hilarious scenes of women seducing him and him being innocent and clueless about everything in the world and by the time he goes back to the real world, he would start explaining to his mom about his adventures and learning new language that his older brother spits out his drink at how he is so fcked...
