Well it would be a good story but then it doesn't make sense (from the beginning with this first game) for this to be in Inceton games "NTR".
It would continue to be just a female protagonist corrupting and cheating and that's it. Where would the NTR be? Nowhere (like this).
Unless it's from Mark's perspective? or another one? Furthermore, it doesn't take away the fact that this 2nd game has to start from an end of this game, which as I remember are:
1 Jen and Mark together (she is faithful throughout the S1 and now in S2 she is unfaithful? The same story reapeated like S1it wouldn't make sense to play S1, it wouldn't even make sense to start from this route).
2 Jen and Mark together but cheating on him with James, if I'm not mistaken with the name (in a S2 DEV has to develop what happened between them, so that she leads a boring life now, something that seems unlikely in that ending of S1, how long will it develop? Who knows).
3 as I remember she gets pregnant with this guy whose name I don't remember Jimmy? (Suppose she's his daughter so how will she have a boring life? and how would there be NTR? if you know what that route is like in this game there is no chance she will fool this guy).
4 She is left alone (Same from 1st game only with a daughter, it would be necessary to develop how she met this NEW husband and how she now leads a boring life).
5 Jen and the open relationship with the spa guy (sorry, I played this a long time ago so I don't remember names well) So here there's no point in starting an S2, not to mention lesbian routes, lesbian NTR?.
In my case it wouldn't catch my attention, if for others it would be excellent.
In general it may work or it may not. It's just a personal opinion why I think it wouldn't make sense for there to be an S2 as well because Season 1 doesn't even say this here Why? Because it is evident that it is not possible, according to me. I emphasize
