The description tag here is completely unnecessary here when the title page of this happily describes itself as "All Futanari Nasty Bitchs", which is a wonderful description for a wonderful CG set.
Our aforementioned nasty bitches include Anko, Shizune, Tsunade, Kurenai, and the series titular gender-changing protagonist who gets 'herself' gangbanged by a load of men. Joy. All, however, sport their own erections to match, so it's all good.
I like futanari. Have you noticed? Giggle giggle Michael McIntyre giggle
