We appear to be talking in circles as there seems to be some misunderstanding. I'll make the points I've been trying to make as clearly as possible, and then I'll leave it. You'll either understand or you won't.
- This is an adult visual novel. It is not porn. You pick from the options available. No more, no less.
- There are plenty of novels where characters, main or otherwise, don't have sex with each other. Can't make that any more clear.
- I'm not talking about excluding any scenes. I've repeatedly talked about how not every scene you might want to see is going to be available, and that just because something happened narratively doesn't mean you'll see it on screen.
- My mentioning kinetic and regular novels is relevant because you inferred that choice and options were what enrich a story. Rather than the characters, storyline, or any other aspect of a novel.
- The stated preference doesn't collide with anything. I stated that I would rather not watch a love interest with someone else unless I'm participating. That's one of the aspects of swinging/sharing. You and your partner set your own boundaries, and one of the ones you can express is your preference on whether or not they have relations with someone while you are not present. The title of the project is Family Vacation, not Random Guys in a Club. If I'm going to watch scenes, I'd prefer it be ones with the family and their loved ones, rather than with strangers in a bar. Pretty simple. That being said, I don't believe it "collides" or excludes any of the people you mentioned; considering that if they are named characters it means they are somehow in the Family's lives.
- Regardless of what the medium is, there is no way to include and "execute" every possible option. Period. If you're watching a porn you are not going to see every possible sexual act, in every position, with every person who has ever been on screen. You're going to see what was written, directed, and filmed; no matter how much you might want to see more. Even in the ones that give you choices, you only get two or three per scene. If you want more, you'll have to watch another porn. The same is true with an adult visual novel. Regardless of expectations, you're going to see what the author has made. That's why I suggested that you find something else. I wasn't saying it to drive you away from this excellent visual novel, rather so that you could find something else to add the things you want to see that you appear to be missing.
In short, this is a great visual novel; not a porn movie. There's a lot more to it than just the sex scenes.
There can only be so many choices in any VN, no matter how expansive it might be. Enjoy what's available, get engrossed in the story and characters that the author/dev has written for you, and enjoy the lewd scenes if you so choose. If you don't find what you're reading fulfilling, add something else to it, while allowing those of us who do enjoy the story to do so unmolested.
Thanks, and farewell.
