I want recs for books where the MMC is so used to taking his pleasure from the FMC. And the FMC is happy to service him, putting his needs above hers. However, later in the book there is a confrontation and the focus shifts to what satisfies the FMC.

The MMC previously either didn't care enough about her pleasure or didn't know how to sate her desires. But there's a "teach me how to please you" moment and that sets off his animal brain. Now he goes absolutely feral for her and makes her cum till she physically can't anymore.

I've only ever read two books with this trope- {Run Posy Run by Cate C Wells} and {Servant to the Spidae by Ruby Dixon} Please don't tell me these are the ONLY two books with this trope

M/F pairings preferred, any genre welcome

Thank you!
