My prediction is; when Nat quit her job she will take some time before she accepts Jenna's advice. At first, she will consent to do only "soft" spreads,
like this, only for the money, it pays well enough, but Nat will be very tempted by more money for the "harder" stuff, reasoning that she 's gone this far, so why not, or with some liquid logic (to relax) lowering her inhibitions. In the "C" routes, Ethan will be over the moon to see Nat become a full-fledged porn star, or in the reluctant route, agrees (or is coerced) to allow her doing some tamer photoshoots. Then Nat will decide to do a soft shoot (whether Ethan knows or not) but then, tempted by the money or revenge does a full on XXX scene with ???
The varying routes all could coalesce into Nat's decision whether to do some adult modeling.
Suffice it to say that "we" don't want just another sausagefest, but rather a story of temptation and discovery.
