Glad my feedback was helpful! On the mismatch thing, what I'd like is to be able to have Theresa keep to a more respectful tone while the jealousy stuff is on in general (especially for *other* characters). No reason why Theresa being a straightforward submissive should preclude Liu calling MC "the third best fuck I've had today" or whatever. Heck, no reason why Theresa shouldn't be able to tell MC about the other people she's fucked on MC's orders without also calling MC inadequate.
(Again, even the inadequacy stuff isn't bad in general—it pairs quite well with having Theresa call you "slave" IMHO.)
