From the moment you choose either romance or dominance, there can be some content with mom or not. As of now, ep.4, if you choose romance you get to cuddle your mom, praise her looks, she'll do a feet pose for you in the bathtub while talking, and give you a sexual smooch in the neck while in the bedroom right before telling you that she wants to be more than mom and son from now on, but she wants to keep it secret. If you choose dominace instead of cuddling you'll grope her ass, you will sneak into her room in the middle of the night to touch her ass and use her feet a bit, and you generally will be more pushy with her, dominant, which she won't appreciate much, but maybe in episode 5 you can get more sex content out of that path/behavior. Honestly I prefer the romance path because it is more love path of a young guy with a 10/10 milf who happens to be his mother than I'm a young, dominant guy who will use my mother for my sexual needs and will not take a no for an answer which is the way of dominance path. I'm just tired of mc's using girls like a sex dolls so if there is a way to have a romantic relationship between mc and his mom I'd choose that. Sex conent will be in both paths, I'm sure of it. It just in one you'll have it natural and in another by force (at least in the begining). It's better to make love with your favorite milf in the game rather than make her your bitch and use her. But of course that is only my opinion
