This does not seem to be the case to me, at least for now.
no betrayal between the LIs has been punished, in fact the initial one with Maya and Josy is rewarded, and it could go the same way for Jill and Bella. even the betrayal between best friends Sage and Quinn has not been punished.
the only adventure we've been punished for is Cathy's with Bella, which is also very undramatic, and probably Jade's with Sage, but even there only under certain conditions and we don't know how.
it's an AVN, you're expected to give in to temptation, otherwise what would they be doing there?
