age gap, power imbalance, icky / weird / borderline taboo

hello everyone!

as the title says, i'm looking for more with age gap (older man/younger woman, preferably more than 10 years) and by icky / weird i mean something like: maybe he knew her since she was a child bcs he's bestfriend with her parents or she's bestfriend with his children, maybe he raised her or something, maybe he had a past with/loved her mother, or maybe just something with very clear power imbalance between them that indicated their age difference (i hope that makes sense???)

what i don't want: - erotica or novella length (nothing wrong with that and i've read my fair share of jessa kane, alexa riley, etc but i'm just not looking for something like that at the moment) - enemies to lovers - why choose, love triangle, reverse harem - extreme ddlg (like the one with enema, diaper, pacifier, etc) - non-human like MCs

books i've read that fit this (that i can remember): - the protege by brianna hale (daddy kink, he took her in when she was 8(?) and raised her until she was 18, their sexual relationship began when she's 20/21) - age your act by eve dangerfield (daddy kink + sort of daddy/daughter play in the sex scenes) - dark fires by brenda joyce (guardian/ward) - embers by claire kent (he's her late boyfriend's father, and they'd lived together with the boyfriend for months or years i don't rlly remember before the bf eventually died) - madcap miss by joan smith (there's not even smut in this but the icky-ness came from the fact that bcs of reasons the MCs worked together to fool mmc's late wife's grandmother by making fmc pretends to be his daughter so yeah)

and last, i'm fine with any subgenre! (contemporary, historical, fantasy, etc).

thank you 💜
