From what I can tell it's a cliffhanger ending. After a bunch of lending sessions she's like "actually, I've been giving you false reports", and goes on to describe more netorare-like events, and then at the end is like hmm, was I lying or was I not? And then the friend that he's been lending her to texts him saying they need to talk in private, and the story ends.
A bit too extreme for me, but I imagine NTR people will like it.
