Futaman!

A new series in the Aoba Q Madou Expanded Universe, giving us a glimpse of Rin's school life. After word comes out that she grew into a futanari, the local (ero) manga club, consisting of only two members, asks Rin to pose naked for them. Reluctant at first, she eventually gets roped into it. Futanari hijinks ensue and if you know anything out Aoba Q Madou’s work, you can guess the whole thing won’t stop at nude sketches.
