No, Marc and Evelyn are not ment to interact with each other, they have their own purpose to explore a part of Myriam.
- Mother-aunt-son-sex with a dominant Marc would be really nice.
I noticed that a lot of people see Marc like if he was the protagonist
No, Marc is akin to the antagonist in classic narratives: he is the active part that sets things in motion, that challenges our protagonist and that causes the incentive and motivation for our main heroine to go on the heroes journey.
If nothing changed, Myriam wouldn't change- but now her son grows up and becomes more like his father, and in some storylines she becomes his slut. This puts Myriam in new situations and makes for some interesting narratives: how will she manage to put up a facade of being the mother in control while she is submissive to her son? How much will she let others know? If Marc insists on a good-morning-blowjob and Anthony as well, whom will she prefer (both will get it, but who will get it first
)? This could lead to some Anthony-Marc conflict (maybe NTR, maybe "open war") or just the opposite (mentor-student-relationship). Whom will she support?
Will she try to fight this relationship and get out of it? Will she try to make it work for the sake of harmony and appeasing Marc?
What about Katherine and how to keep it secret from her? Or maybe she will be corrupted as well? Or maybe Myriam considers it's best to make Katherine accept Marcs dominance over her slowly, but steadily?
Or imagine casual scenes of family-being-together, but twisted in the way of Myriam being her sons slut and therefore things play out slightly different.
And even if Marc wants to get all the girls, the story is still about Myriam. Maybe she will help him getting a harem, maybe she will be cuckqueened, maybe she will protect him from stupid mistakes, maybe she will have to cover up something for him. Whatever it is, Myriam is the focal point, but she is not the one benefitting from it.
And maybe that's important: she is the protagonist of a story about her life, where others like Anthony and Marc decide much of what happens (if she is on those paths) and Myriam is on the receiving end. How she deals with all of this, how she solves these "quests", "challenges" or "changes" and how it changes her- that's her story. Imho.
Well, for the first case, depending on Anthony's presence or not, she will have or not to drop him off, so I just used the other possibility to give William a scene again.
I can understand some disappointment about missing content here.
I kept Anthony, but kicking him out could also be motivated by wanting Marc to have all the freedom and opportunities.
