then i look for curved shota. ;p joking aside there's not many novel had shota as mc what i know only CCM, if you're not talking about mc but shota only nothing i can recommend.
Commushou no Ore ga, Koushou Skill ni Zenfurishite Tenseishita Kekka Though it was stopped translated, because of the author making changes so the story is less ero...
Not sure if its what you're looking for but these is a few of younger male x older female manga. Just a manga with NO hentai. Merupuri - This one is kinda special because the Mc can switch between 2 form. His kid form and his older form. https://www.mangaupdates.com/series.html?id=843 Please save my earth - Reincarnation, past lives and ESP. https://www.mangaupdates.com/series.html?id=1245 Boku o Tsutsumu Tsuki no Hikari - Continuation to Please save my earth (sequel) https://www.mangaupdates.com/series.html?id=386 Dear mine - About a genius rich kid x older girl who is older than him a few yrs. https://www.mangaupdates.com/series.html?id=4352 Soredemo Sekai wa Utsukushii - Little king x princess older than him few yrs. There is even an anime of this one (pretty much new). https://www.mangaupdates.com/series.html?id=72487 Game Over (MIZUTANI Fuka) - A pretty short complete story. If anyone read 14-sai no Koi before would know this one since it is part of it. https://www.mangaupdates.com/series.html?id=56401
Following that logic, one could ask, "what's with all the loli hype" as well. Difficult to question other people's fantasies, however weird they are.
Depends on if you need the age difference between the two to be rather noticeable, or if maybe just a few years' difference will be enough. Or maybe you would be happy with a 'Legal Shota' with a much older female? Also, you said Does that mean the two of them have to be atleast good acquaintances or possibly more?
Mahou Tsukai kurohime the male mc isn't exactly a shota but he's young the female mc is mature it's a manga btw, surprised no one mentioned it, and it's a personal favorite
I don't know if you're a fakin troll or you're just someone who can't see Mt. Tai in front of their eyes what he meant by "male is shota and the female is not" as in romantic relationship, he/she prefer the male one as shota ( litle kid or under age or just say a boy) while the female one is not "shota/loli" ( a woman or a lady or best said older woman) while "straight" mean that it's normal relationship beetwen male and female not some gay, homo, lesbi, yuri, yaoi etc basically OP said he/she want a story between a boy and a more older woman to OP if you good with manga maybe try read Im Dal Young's manga, like UnbalancexUnbalance, The Legend of Maian, Sai:Takers even though it's not complete shota but it's more like Young Man with much more older woman,
There should be some shouta mc x oneesans.. But I never see an oneesan mc x shouta.. is it even popular? I cant recall
There's many at Hentai story , but i can't remember the novel title's or remember the exact story because most of it is you know just For Academic Purpose only, besides it's been ages since i last read good plain hentai or good hentai ah I remember, Aki Sora is good shota read if you can put up with the soft H, read the manga coz the anime sucks
