So i read the entire thing which was very short and to what i know of there isnt much further plot other than this manga about a girl who wants to seduce her brother and uploads lewd pictures of herself on Twitter.
In terms of the manga it was pretty straightforward however what put me off it was that on the very last page we get a description of the characters and only then did i find out that Erika ( the main character ) was a middle schooler and while she looked young i had hoped she was AT LEAST of a legal age but i also don't understand how a middle school was allowed to buy/afford sex toys and how she got away with posting cp on her Twitter :L
Despite this its just a crappy hentai manga nobody REALLY cares about the plot or loop holes in it and maybe im just being bias because im not a fan of incest or age gaps
