I think yaoi is more preferred over younger girls compared to like hentai because hentai has less plot/story, less emotions, more full blown sex. Girls want to read the drama, angst, twisted cool stories, and get into the character development of cute ukes etc. Yaois put much more weight on incest than hentai unless the hentai fetish is mainly about incest.. but for bro x sis, it's not major. For hentai, major incest taboo are like mother x son. And there's limited bdsm hetero that isn't hentai.
Yes! Drama! Twisted stories! Cute ukes! they all rock!
My only problem is how manipulative the seme was. I don't mind rape or insest.
I love bondage and taboo relationship when done right, I hate straight couples (bro x sis ) but for yaoi I can never dislike a "good" incest as in when they treasure each other even in a very twisted dark way.
And for people that are complaining about the sadist seme and the incest, it was pretty obvious from the first panel. It literally had the uke bound to a chair with a vibrator on so it can't get any more obvious than that. You should've quit reading by then instead of reading the entire thing and complaining in the comment section
