Please, I’m losing the hope.
How would you commit incest unless “We are horny, let’s fuck.”?
Incest (nowadays) is usually considered illegal, immoral, disgusting, strange, wrong, unconventional, satanist, perverse, inhuman, stupid, contrary to morality, and so on and so forth, consequently, IN MY OPINION, although porn is often very silly, naive, and aimed at getting the characters involved to fuck regardless without beating around the bush, perhaps even on an intrinsic level, in order to do something more exciting, original, and interesting, you have to use a pretext other than “We’re horny, let’s fuck.”.
I think it is very difficult, normally, for someone to screw their father, mother, brother, sister, etc…, consequently seeing them do it without too many difficulties can be fun or a pure and simple realization of a fantasy aimed at satisfy those who are interested, but in my case, after having had contact with hundreds of porn, I don’t even get upset anymore when I see the usual banal, obvious, and idiotic spiel, that’s all.
Try reading “Hearts” by Romulo Melkor Mancin, “Family Temptation” by Hyji, “Mother’s Helping Hand” by Dick_Spanker, or “Helping Hands” by Shyquirter, and tell me (at least if you’re a fan of incest or otherwise turn you on) if they have the same quality as the average incestuous porn.
Have you tried Sister Love by Perverteer? All of the girls need convincing, and each one requires a different approach. The way the mom gets brought in is…pretty unique. I’ve found that your storylines are all more or less locked in (or out) by Day 6, and the choices that make it happen can seem very innocuous! After that, there are secondary characters to pursue and the pregnancy or not options.
Heavy Five is a sci-fi themed game, and the incestual pairing happens because other characters maneuver you into it. Not how if/how it continues, it was a few updates ago, I’ve gotten behind.
Now that I’m thinking about it, there’s Guilty Pleasure, which the group they were in manipulates things so he gets paired off with sis in a spin the bottle campout; it was a prank move designed to blueball our boy while everyone else got lucky, but after everyone else fucked and fell asleep, she goes, “let’s do it too, but real quiet” followed by “that was great, lets keep going!” which then starts pulling the other sisters into it. Kind of what you were trying to avoid but about the mildest possible manifestation of that, so maybe tolerable, my playthrough is still in progress.
Boy Dominates Sexy Mother (love the acronym) is unfinished and will forever remain that way, but what there is of it is pretty intense, being pretty strictly a blackmail storyline.
I love redheads, and Junior72’s excellent (Honey Select) art, but there can be too much of a good thing. Every single girl in “Lost & Found” is a redhead, even the one that isn’t (green dye, she reverts back to natural almost immediately). And his story is everything OP is trying to avoid…not just “I’m horny lets fuck”, but immediate “me too!” , “me three!”, and a fourth “don’t leave me out!”
For non porn fiction that covers that ground, there’s Robert Heinlein’s “To Sail Beyond the Sunset”. There are serious discussions of pros & cons, “there are reasons its against the laws of God & man” (namely birth defects in resultant children).
Fun fact: hemophelia exists because of incestual children born of Russian royalty. It’s always the royals, with their emphasis (and exaltation) of “proper bloodline”.
