I love Caroline's story and she is hot as fuck(No.1), I like Lily more than Sara (don't hate me for that), Celia and Violet are awesome (busty girls are my thing), Linda is too aggressive at the beginning, Yazmin is such a tease and for the rest there isn't enough content to comment on them (I hope there will be soon, especially for Judy, Macy and Delilah).
Linda by a landslide !! She's one of the few moms in incest games that don't need to be blackmailed or mind controlled, or convinced to break the taboo, she has been grooming her son for sex since he hit puberty !!
That licking scene is one of the hottest non-penetration scenes in any adult game ever ! Probably helps that I think the MC is insanely attractive (man-pretty), cause that scene would be dog shit if the male in question was Eric's model with his shit eating grin, or Liam's model, or Jack the lawyers model(generic fat guy) or Davide, or D'Brickshaw, or any male from The Bully...
Caroline is a very close second, she is insanely hot, probably even more so than Linda. Linda edges her out due to oozing sexuality like crazy.
