Futaman!

Rin is a high school student who has developed into a futanari, a secret that quickly spreads through her school. The local ero manga club, consisting of only two members, approaches her with a bold request: to pose naked for their artistic sketches. At first, Rin is hesitant and refuses, but the club members persist, and she eventually gives in to their persuasion.

As the drawing sessions begin, what starts as innocent nude modeling quickly escalates into something far more explicit. The club members push the boundaries, and Rin finds herself caught up in a series of increasingly lewd situations. The dynamics between the three of them shift as hidden desires and tensions surface, turning their artistic collaboration into a web of sexual experimentation and unexpected encounters. Rin must navigate this new and overwhelming experience, where nothing is as simple as it first seemed.
