Looking for a specific hentai manga.
Basically, a girl confesses to a guy he likes, but finds out that he's fucking his stepsister. The reason is because he has a condition where he has to have sex every hour or something like that, so the stepsister takes the responsibility of satisfying his urges. The sister then trains the new girl to be able to satisfy his needs.
