Natsume-ke No Nichijou [English], by Katsurai Yoshiaki
« A femme fatale, an absolute male magnet. Her sexual appeal could almost be described as “bestial”, as if she were somehow exuding irresistible sexual pheromones from that alluring body of hers. » That perfect description, for the first of the two sisters of the male hero, starts the manga :3 The second sister is no less of a sex hound, also uniquely and obsessively directing her lust at her younger brother, only that she’s falsely looking composed and innocent to outsiders
And thus, these three siblings are drawn having TONS of happy threesome time. Besides the thick censorship rectangles, the only thing tarnishing my enthusiasm would be the slightly abusive nature of the girls, as the brother, although consenting, is never given any choice and is pushed into wanting even more sex.
The sexual intensity was extremely high, almost no page was wasted on anything else but sexyness. I loved it Thanks a lot, for this release, to Wehasband, Hihohahi, Mikocon and CellTF!
