Sorry this is twisted one http://www.mangago.me/read-manga/ibitsu_no_kakera/
Incest as an anyone related? Adoptive, step-family. Or blood related incest. Their is a lot of manga's i know that are considered Incest by law but no one considers them incest because their is no blood relation.
http://www.mangago.me/read-manga/love_prism/ and one of the stories in http://www.mangago.me/read-manga/sailor_danshi/
Even if you just want brother x brother, sailor danshi has great art, even if the characters re a little more muscular (they're still adorable!) (^ v ^)
Most BL family affairs are stepbrothers.
