Health Education in a World with Futanari

A teacher announces a lesson on the physical differences between men and futa, selecting Ren Sato and a futa classmate as representatives while fellow students look on. Clinical charts, a pink examination machine, and absurdly exact figures for erect length, sperm size, ejaculate volume, count, and motility turn the classroom into a bizarre medical comedy. The demonstration grows steadily more embarrassing as intimate biological data are measured, displayed, and openly debated.
