I'm with you man. I can go either way with incest too. It's not really one of my kinks (though siscest is bestcest).
I usually like to go with whatever it seems the intended relationship is. Usually when there is a choice like "what is she to you?", that's usually a pretty big hint that incest is canon, so I initially went with "sister". However a lot of the dialogue feels more like childhood friend makes more sense. Like, Clarissa doesn't live in the same household, or how it's "Clarissa's mom" even if you chose the "sister" or "cousin" variable. Another moment that comes to mind was the "Corey vs. Steve" convo in the girls locker room. If they were siblings or cousins, then it seems like the other girls would have teased Clarissa when she made that comment about him. Like "Oooooh Clarissa wants to fuck herinverse_clarissa_relationships
!!!, but they didn't do that. They just simply told her to pick from two other guys.
...but then she mentions bathing together as kids which is usually an incest trope, and that dialogue is the same whether she's a sister or childhood friend. So its like 90% feels like childhood friend, but 10% feels like they might be related? A childhood friend with a really really close relationship growing up?
It's hard to explain, but usually when incest is intended it's usually more obvious in the dialogue and that it was changed for patreon... but it feels like the opposite in this case. It's like she was legit written to be a childhood friend, but the dev added the incest option afterwards for the sake of fan service for incest fans. Pure conjecture but that's the way it seems to me.
Eh, anyway I think I'm vibing more with her being a childhood friend, so I'll probably just redo my saves lol.
I'm like you (incest is not my thing/not a dealbreaker for me), that said, I prefer it (and all other kinks) to be done well. As is, it feels superfluous and jarring, like the Dev only put it in to attract the crowd that is absolutely ravenous for it*.
Also, some other commenters have pointed out the deficiencies with the sex scenes. I believe this is easily a five star game and deserves tons of monetary support, however the sex scenes are the weakest point by far. Too many choices, each of which makes the game hang for a good five seconds after clicking. Animations are short and repetitive and the whole scene is rather abrupt and undeveloped and then done far to quickly (probably a sex metaphor about premature ejaculation and no foreplay in there somewhere).
I think the Dev has a strong command of the english language and general passion for writing, so I would recommend he simply do less animations for now, and add more stills to the sex scenes with about twice as much descriptive sentences and maybe some 'oooohs and ahhhs'.
I also think there's too many LIs.** I know it's anathema to say that around here, but character bloat ruins games worse than anything. It slows down the entire story, prevents any sort of depth or growth (which is surprisingly important in AVNs). Like incest it's more of a financial decision than a creative one and it's always a bad choice. I can't think of a single game where there are more than seven love interests and its still viable. And frankly, seven is a ridiculous number.
That being said, the dev could change nothing and I'd still support. This game is top tier.
* Seriously. i understand it's your kink and I swear I'm not judging, but when you make an entire massive mod to change an entire game's LIs to incestuous in a way that breaks the narrative of the game, I begin to question your overall mental health. Looking at you, guy who made the incest mod for Being a Dik.
** Please don't throw things at me. At least not in the face!
