We Are Reproducing私たちは繁殖している; Watashitachi wa Hanshoku Shiteiru; Watashitachi ha Hanshoku Shiteiru; We Are Breeding

Award-winning series by author and essayist Uchida Shungicu. A frank, sex-positive look at pregnancy, childbirth, child rearing, and single motherhood. The series is tagged as Erotica because it has sex in it, but if you're looking for an erotic manga per se, you'll probably want to look elsewhere.
