I'm still wondering about how the sharing D with Martin event can logically occur.
Yes, I know this is a game and not reality, but the Mr.Dots team has tried to keep some air of plausibility intact.
Unless (a very drunk) Martin catches D and her daddy fooling around (like everyone else has done) how could the MC bring up sharing his daughter?
I could see a scenario where in D and the MC planned for D to seduce Martin into having sex with her first (as the MC and Elena watch via a spy-cam and have sex themselves). Afterward maybe the MC "catches" them. A discussion with heavy drinking follows and ends with D getting spit-roasted (as Elena watches and records via the spy-cam for sharing with Jennifer later).
At the moment there is no evidence that D is interessted in fucking another man. Maybe there is curiousity, if you watched the BBC porn with her, and she and Elena just wanna check out if this prejudice is true? And they got caught by him? I don't think there will be a one on one situation getting hot between D and M alone without a catalyst.
Or there is, again with alcohol involved, some misunderstanding. E is flirting heavy with him telling him to come over at night, D and E wanna fool around too, and based on some 50s movie due to circumstances they are in different beds. So M joins not E but D and D thinks it's Dad?
On the premise that M first visit implies a harcore scene between D and him. Maybe there is none?
