As the title says, incest slow burn games. Not necessarily very slow burn but just where the family doesn't slut for your dick immediately. Where you have to corrupt the naive and innocent ones.
1) Big Brother (and MANY of the different versions).
2) Last Hope
3) Midlife Crisis is relatively slowish burn
4) Culture Shock takes a while to get Family Fun
Grandma's House
LI's that are incest are (As in MC is blood related)
Grandma (Slowest burn)
Aunt 2 (Long burn)
Aunt 1 (Fast burn)
Cousin (Daughter of aunt 1 and fast burn)
Then there is a character who is a bit of a mother to MC as well.
Be aware there is a ton of LI's in the game.
There is also other blood relations that MC in involved with as in 2 females who are related just not to him.
In fact there is a family of gingers you can get with.
Only 7 LI are unavoidable, all others are optional and there is a large variety to choose from.
Light of My Life is one of my favorites - I subscribed on Patreon. There is just something about those two daughters.......I dunno, I just really like them.
