There's room here for both versions of NTR/sub, one with her enjoying it (corruption) and the other with her suffering it (humiliation/rape).I want to see her getting forced by her boss or others (coworkers maybe?). I want her to struggle a bit not outright enjoy it.
Her affair with her boss started with blackmail it should continue like that, eventually Tony pushing Lara to others.
Her last scene with him was a bit underwhelming for me, because of her enjoyment.
On the other hand, if there was an alternative NTR/dom subpath as I suggested, I'd only open the possibility for the MC to discover what she's doing in this one. In a way he might even feel proud of having such a strong partner
