Well, I don't know if I would go for everything you proposed, but I liked your post anyway, because part of the forum is also the possibility for us to toss some idea around, even if then they will never get in the game (remembering Zorlun had already fixed how he wanted to develop the story and the characters, and is not sure how much he is willing to compromise on the details for that).
It seems Zorlun is reserving the possibility of "bestiality" for Myriam, so I guess he would object to having Jennifer involved in that, and it is in unclear (not to say improbable) he wants to introduce in a visible way Jennifer's parents or even just one of them (it would seem probable if Myriam had to do it with others, the first time would feel more comfortable doing it with women, which would mean Jennifer and her mother).
He already indicated Jennifer is supposed to be a bit the wild and exploring all kind of things, and supposed to give some inspiration for some exploration by Myriam and hopefully also Katherine, but apparently if I remember correctly more on "sapphic only" way.
In reality, we are given the possibility of pushing Katherine towards being interested only in women, only men or both, but if I remember correctly, Zorlun excluded the idea of Katherine doing anything with any male (whether involving also Myriam or not, and independently from the situation, location, and quantity of males available), aside excluding very explicitly the possibility of Marc getting his way (or maybe even just trying and failing) with her.
So, it seems not all the choices are actually an indication of possible paths or events.
Actually, if I got it right, the motel and the stables are not in the same direction, the motel was kind of lost in the middle of nowhere, the stables are closer.
And honestly, for her to do stuff with Dumdum, there is no need to have any kind of rape scenario with the motel guy.
In the end, the same way in which her sweet side and identifying Dumdum with her younger brother made if possible (if chosen by the player) to have the shower scene, it would be kind of fitting that if she encounters again Dumdum, she may be given the possibility (at least if she did some choices the first time they met, at least the choice of taking the shower) of making Dumdum a happy boy ;-) ("mom says it's wrong to do it with bad women, but she is a nice woman", as he would say
).
But it is not clear if the motel guy and Dumdum will ever come back, or they were just a plot tool to allow start branching different paths.
