I'd say the porn scenes are worth it if you don't mind reading. They are few and far between, but it's more of an interaction between the characters that makes it a good scene.
To me, it's a good book with boobies, pubies and orgies. I am usually glued to the screen every time a new chapter comes out, it's a well written story, I like the characters and development. And the humor is just too good :)
If you are involved in the story, the porn scenes will make it worth it.
If you want a more simplistic story with a lot more porn, look at Tropicali, also by StoryAnon. You will miss some references to this game, but it can totally be played standalone.
