Both involve love between a twin brother and sister. 
report Recommended by yaoiisgood
Two anime that deal with incest without glorifying it, or attempting to pander to those with a fetish for such things.

People are often put off Koi Kaze due to the age gap between the older brother and much younger sister. Boku wa would probably appeal more to those people because the siblings are twins.

In both stories the leads try to fight off their romantic, lustful feelings for their sisters; ultimately failing to do so. And in both it's made crystal clear how society views incest and the hardships brothers and sisters in love must face. Neither title is smutty... though, going  read more

both contain the same style but unlike the innocent Aki, the protagonists of Boku Wa is more serious in their choices, the brothers live with their parents and friends during the story, what is something that does not contain in Aki-Sora, the fine is and as dramatic as the note is the same, 10

Both animes have brother/sister incest motive, with the brother being in love and the sister submitting to him out of devotion. Angel Sanctuary, though, has a lot of additional interesting stuff, Boku wa Imouto is a pure realistic drama.

Forbidden love is one of those genres in the anime world that's explored in both series.

In both series, there is a forbidden romance between the main characters. Although Onegai Twins focuses more on a love triangle, both series contains rivals and drama.

Both series also has comedy although Boku wa Imouto ni Koi wo Suru focuses more on the drama side. Additionally, both anime(s) have that mature and emotional side where the main character struggles to find his way throughout the story.

Both stories are about love between two siblings aka incest, especially with the brother trying to hide his feelings for his sister.

Both are romance animes with forbidden love.

And ofcourse both have cute girls.

One is a serious anime while the other isn't.

One starts with a brocon while the other starts with a siscon.

Both had a unique love story, both had beautiful art styles and both are worth watching if you like dramatic romance.

Both anime have the brother and sister relationship.

The difference between these two is that boku wa imouto ni koi wo suru is a serious drama about falling in love with your sister while oreimo 2 is also about falling in love with your sister but with humor and more on playing eroge games with your sister.

About brother's and sister's love. Incest.

These series aren't very similar, but both contain forbidden relationship between canon Romeo and Juliet and between siblings

Both have sister and brother falling in love and struggling through hard times caused by friends and family.

While Utena is by far more complicated, what both animes have in common is a brother/sister incest motive. 
report Recommended by Juxian
Even if being different in plot and length, both are smutty anime with plenty of drama which involve love between twins (even though Imouto has actual incest, while Ceres doesn't).
Also, Aya and Iku are very similar: both are blonde, dumb and quite annoying schoolgirls. 
report Recommended by RenaPsychoKiller
Condensed OVAs of stories about the troubled relationship between co-dependent siblings. Hitsuji no Uta is thematically darker, but its incestuous undertones definitely draws comparison.

Sister complex and going beyond the boundaries of morality. 
report Recommended by hokeymon
Both are very heart warming storys, where all of the characters are very easy to relate to. Also, both of the series revolve around a couple who are brother and sister (even though in marmalade boy the couple are only step bother and sister!)

Brother's conflict has the main protagonist's brother in love with her. The brothers are also extremely gorgeous and the main protagonist also seem to be a weak girl who seem to have difficulty rejecting their affection
