Power Vacuum fan fiction 18+

This is fanfiction story of Power vacuum. An adult visual novel by What?Why?Games on patreon.
The original work involves incest, manipulation, impregnation and skippable NTR.
This is the story of Sterling who tries to save his loved ones from falling for a devious, monstrous creature that ever stepped foot on media. It's his grandfather Hunter. I recommend you to play the original visual novel. It's the funniest visual novel I've read.
Here the lik to the original game:

The original story has NTR (skippable) as non canonical part of the game. Which means that you can see the outcome of NTR choices but they don't happen in the main story. You get to sabotage the Ugly bastard's plan and watch him fail where you conquer.

My take on this fan fiction is to make some changes in some of the character's personality. Also I'm resurrecting his dead father David. I want to make the NTR part skippable here but in novel system, that's going to be a issue. So, the story will be divided into three volumes. These three volumes aren't connected to each other so the readers can read what they like and skip the others.

1. Harem: MC gets a Harem and takes revenge on his father too who made his life miserable along with hunter. Here the MC is buff and well trained fighter from rhe beginning. He can go toe to toe with Hunter who has simple but efficient fighting skills.

2. Netorare: I'm going to make some of the NTR elements as Canon to move forward in way that would make sense.

3. Netorase: MC and his enemies have equal advantage in this volume.
