Fics like Futa Academy: The Rising Star of Seikaiju Academy

Seikaiju Academy is the shining star of Toshima, Tokyo, though it has a secret - it is one of many Futanari Academies, schools secretly chartered for the sake of Japan's futanari minority. At Seikaiju, a strange economy has formed: penis length may be transferred between girls with only a verbal agreement and a quick rut in the bathroom between classes, and the larger your dick, the more clout you have. The largest girls are Class Representatives on the Student Council, with the largest of the four being Chairwoman of the Council. There had never been a freshman Chairwoman before, but that won't stop Yuriko Takashima from forming a pyramid scheme of dick with her at the top, as she aims to become the future Chairwoman of Seikaiju Academy.
