Hold up, all that effort put to corrupt her and steal her away humiliating the BF just to dump her and give her 2 pages of her becoming a cum dumpster of random guys? Seriously?
Okay, I'm not even mad about the story being too cliche EVEN for the NTR... forget about it... The ending is just... another level of being the bottom of the barrel... Well, as they say: "We thought we had hit rock bottom, then someone knocked from down below" or something like that.
