A Bright Family Planning [English, Incest], by Kikkawa Kabao

That was the funniest hentai story I read since three weeks, this hentai manga ^_^

(Remember to view the updated list of all Kikkawa Kabao’s works on hentairules)

Basically, thie story is about a father-asking-himself-too-many-questions-about-his-kid’s-welfare (just like me, in fact) who realizes his son and sister have incest sex, peeps on them and is confronted with very essential questions (for god’s sake, I don’t want to ever be in a situation like him when my kid grows up :D). The story being narrated from his point of view, that’s very funny, really
