example :
Ayu Mayu

Any manga?

This will help.

I can really recommend KissXsis 😃

I need a die with 2 sides.

That's known as a "coin".

Oh, thanks. Too much D&D.

oniichan control is exactly what your looking for, as is the aforementioned KissxSis.
also Oniichan no Koto Nanka Zenzen Suki ja Nai n da kara ne!! (longest manga title, ever!)

Do but despise reason and science,
The highest of all human gifts -
Then you have surrendered to the Devil
And must surely perish. - J.W. von Goethe

I think Onichan control is a bit more perverted than Ayu Mayu though. I still enjoy it, it may be wrong but it's funny.

Favorite Manga:

Midori no Hibi
That is all.

Oniichan Control, KissXsis and probly Oniichan no Koto (I haven't read that last one yet) are what you are looking for, but those wont be like Ayu Mayu, since that was more like a light romance manga and not really a incestuous story. I really didn't get the feeling he was dating one of his sisters during the story... Anyway I personally love KissXsis, lots of ecchi stuff and not just fanservice, however everything is censored 😛 , Oniichan Control is on a nice start, however the sister is freaking me out.

Koi Kaze is an other siscon related series that portrays a much more serious and taboo view of brother-sister relations.

Yuuhi Romance is more of a brocon short story, it's also a light read on the subject, not as hardcore as KissXsis or Oniichan Control.

You might like Chokotto Sister, isn't really siscon however, but in some ways it is...

I don't know many more, but however if you liked Ayu Mayu, you could try some step-sister/sister-in-law stuff (daugther of man/woman that remarried to your mother/father) like Parallel (bad example... ) 🤢

PS: Oniichan no Koto's art looks like some brocon incest h-manga I saw, so maybe we can expect something along the lines of KissXsis
