Obviously, you are looking for something that Harem Hotel is not, a fapping, sandbox game where sex is the main point of the game.
Why then, did you choose to play a visual novel?
They all have stories, which means lots of text.
Which means longer gaps between sex scenes.
Before playing any game, it is always a very good idea to go to the comment section and read some of the posts, to see what others think about it, and to ask questions about the game, such as is it any good, does it have a story, what is the plot behind the story.
If you had done that simple little thing, you would not have downloaded over 12 gigs of a game, that has a strong story, lots of text and a plot that you apparently do not like.
If you just want fapping material, you chose the wrong game to download.
Because, as I said, this is a visual novel.
F95 has tons of sandbox games with limited story, so I suggest that you switch to one of those, instead...
So, rather than wasting your time badmouthing a "VISUAL NOVEL" for having a story and plot, simply because you don't like the fact that it has a story and plot, why not spend your time looking for a game that focuses on sex.
Which appears to be all that you are looking for.
