Looking for specifically Twincest**....twins must love each either not someone else.**..thanks in advance ^^

There's a category option for this: http://www.mangaupdates.com/series.html?category=Twincest
I hope it helps 🙂

incest is wincest, but twincest is the best!!!

now, since you put under yaoi/yuri i suppose you dont want the straight kind. so:

Inferior Male
Junai Virus
Koiyami Archive
Nureru Karada (YAMAKAMI Riyu)
Netsujou Innocence
Nanadome no Gomenne
Tonari no Shibafu

read the description for some because they are part of a collection of short stories.

Thanks both ^^
