Boku Wa Tomodachi Ga Sukunai hentai doujin [English] : Butterflies, by Kaigansen

Sena wants Kodaka for herself, so she makes sure to have sex with Kodaka right when Yozora is coming.

At this point, either you have read or watched Boku Wa Tomodachi Ga Sukunai, and this turn of events may be of significance to you (this is a bit ugly, love rivalry solved with the good old “first to fuck books the guy” rule), or else you can simply not give a fuck and simply enjoy the drawings
To my amused surprise, this isn’t a Little White Butterflies release, but a Cgrascal release, haha, despite the name of the doujin ^^
