Cousins had a crush on my non bio cousin for a long time and it pairs well with that. Brother Sister too the the taboo mixed with the complex emotional dynamic really packages a lot of character development into what is normally not very well thought out characters.
This isn't always the case, but i've found that the questions the BS relationship adds to a story make it much harder for a new writer to accidentally make them one note.
For a younger MC, Sisters, Definitely, Bonus points if the MC's Twin or its Twin sisters. I'm fine with Aunts/Mothers though.
For an older MC, Daughters, and especially sister if she's canonically the mother of one or more daughters already.
doesn't matter as long as it's close family, no step-bullshit unless it's really important for the story
not like it's shitty mainstream porn acting, it's full fiction - imagination is the only limit
oh what i gotta choose now?! *cry*
id have to rank f+d(d) first b+s, s+s, m+d im not that into m+s. ok guess choosing wasn't that hard and i mean any extended fam is hot with a good story really a nice story is the make or break.
I enjoy the act of corrupting in games and mothers daughters and sisters all have different approaches that make them all fun in their own way, that being said usually the naughtier the better. As long as its well written
As long as the relationship is believable and doesn't feel forced for the sake of lewd/sexual content I dont really have a preference. Theres a whole lot of variation with this one so if i had to choose. Id say i lean toward a more 'whole family' concept.
i realy like daughter/father content like Dating my daughter. When the father reconnect with his daughter and must try to know her again... with tease... a lot of tease!
Father/daughter

non incest of similar age ranges
grand parents
I like it when a game can actually write a realistic relationship and it isn't just "I am your sister so I must have sex with you". That being said I hate grandparent stuff.
This might sound odd, but for me it goes Twin, Cousins, then regular siblings. Dunno why, I find twins together incredibly hot, cousins are also great but way under explored, and normal siblings are... Like, alright. Kinda basic tbh. Do love any elder sister stuff though.
Anything parental or with a large age gap squicks me out tbh. There'll be some that I enjoy and it's not a deal breaker if it's in a game, but depending on how it's written it can actually become one.
