Sorry to make people wait. Here's the followup to Ota Imouto ga Namaiki Sugite Meiwaku Sugiru .

Notes
• The movie they are watching on page 3 is 魔界都市 ("Demon City Shinjuku"). Its DVD cover is the one seen on page 1 .
• The novel Konatsu is reading at the beginning is 魔宮バビロン ("Demon Palace Babylon"). Interestingly enough, "Demon Palace Babylon" is the sequel to "Demon City Shinjuku". Perhaps that's why Konatsu was willing to watch the movie.
• The book cover on page 14 is 銀河英雄伝説 ("Legend of the Galactic Heroes"). Siegfried Kircheis is a close friend to Reinhard von Lohengramm, the main protagonist of the series. The two of them help overthrow the Goldenbaum Dynasty. It appears that Konatsu pretends to be Reinhard in her fantasies.

@slimeyx
The word that I translated as "brother" is 兄上, Aniue (a respectful and somewhat archaic way to refer to an older brother). The thought didn't cross my mind to 'translate' it to Onii-san, but I think it provides a better gap when Konatsu subconsciously switches to saying "Onii-chan" .
