This is the story of a girl in shimapan with a brother complex.
Here’s Nao. Isn’t she kawaii?
There’s nothing she wants more than to do kinky things with her brother.
Her onii-chan, Shuusuke, wakes up to her snuggling in his bed.
He seems to have some interest in her, too.
“Whoa. She looks so cute when she’s asleep.”
She moves in a little closer. She knows exactly what she’s doing…
He’s thinking about it. Will he kiss her?
Mom busts in for the cock block!
Mesmerized by the pantsu.
Next day Nao sees Shuusuke walking to school enjoying some toast.
Here are Nao’s friends: Haruka (left) and Hirono (right). Nao is pissed because she didn’t have breakfast, but her damn onii-chan did.
Perfect opportunity for more teasing, I guess.
She bounces back to her friends.
Flashback to when she teased Shuusuke at the theater.
Another flashback to when she teased Shuusuke while playing video games.
More lewd Nao fantasies.
Nao leaves the bath with a plan to tease her onii-chan further.
But that mutha fucka may have stolen her ice cream!
Yep, he took it!
She ends up showing more than she had planned.
Mom again for the cock block!
Trying to play innocent now.
Next day. New mission: Find onii-chan’s porn stash.
She flips up his bed (and her skirt because physics).
She finds a hidden family album.
Why isn’t she in these pictures?
She confronts her parents about this.
More pantsu because why the hell not.
Her parents explain that she and Shuusuke aren’t blood related, opening the possibility for her lewd fantasies to become a reality. She’s ecstatic.
She wants to do this.
And eventually this.
More bliss (and pantsu).
And more random fantasies for the sake of adding service.
Oniichan no Koto Nanka Zenzen Suki Janain Dakara ne!! (Because I Don’t Like My Big Brother At All!!) is a little funnier and heavier on fanservice than the typical ecchi-comedy. If you like implied incest, and petite girls with round ears who flash their pantsu constantly, this show is worth checking out.
