During their coming of age, they each come to realize the true depth of the love they feel for each other and consummate that love in secret. They keep their younger sister, Nami, Sora's twin in the dark about their new relationship. Nami, clueless of what is happening in her household aims to set her brother up with her best friend, Kana Sumiya. Despite these relationships, Nami seems to have feelings for someone near to her too but keeps them secret.

Aki-Sora isn't your run-of-the-mill brother-sister incest story. There have been too many OVAs to count where a boy and his step-sister(s) of no blood relation at all, made quite clear early in the story, have expressed their forbidden love. One of the attractive points of Aki-Sora, though, is that Aki and Sora are, in fact, full siblings. Finally, the 'I' in incest was dotted, and the 'T' in taboo was crossed, like the line that Aki and Sora cross when they give in to their desires for each other.

A point I find particularly appealing about Aki-Sora is Sora's twin sister, Nami, whom he is not read more

IMO, this is the top of the line in borderline hentai & taboo.

This anime doesn't hide its taboo. No sir, its full blown incest. Unlike kiss x sis where they are not blood related and the story shoves that in your face on multiple occasions, Aki-Sora casually mentions. It doesn't try to justify that what they are doing is socially okay. It doesn't give a fuck.

The scenes are amazing. Nothing is shown of course, but its still amazing. Considering the fact that sex isn't just one pose and that's it, it varies from scene to scene, moment to moment. It has more to shown than read more

It has been a long time since I saw a good incest story like this one, not since Boku wa Imouto ni Koi wo Suru. This innocent, pure love between Aki and Sora can only be described by the actions they decided to take, the emotions they shared with each other. There’s nothing wrong with their love, nothing at all; you can’t call it dirty, because if that love is pure, honest and sincere, it can’t never be wrong.

If you really know how to appreciate an incest relationship without prejudice, you’re more than welcome to see it.

One more thing, I think there’s a read more

A lot of you probably think I'm bashing this solely based on the incest factor. However, this is not the case as there are genuine problems to be adressed. When it comes to story, not much is going on. It's just a young boy perving over his older sister, discovering that the feeling is mutual and them having intercourse. The main problem with the story is that the OVA doesn't know if it wants to be a serious melodrama or soft porn. The prolonged sexual scenes detract from the drama and after a melodramatic love confession it feels somewhat out of place. This creates a read more

Both have brother & sister intimate relationships.
Both deal with brother and sisters relationships, and both are ecchi
One of the few animes in the Mature Ecchi Incest genre.
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
Similarity :
+ Both anime about love between siblings
+ Alot fanservice

Different :
+ Sora only have 2 sister
+ Youtarou have 13 step-sisters
Both anime about love between siblings
Only if you like romance between mio & Shuuichi
