[Hanpera] Public Health Doctor's Practical Teaching [joobuspaidatr]

A hopelessly repressed futanari schoolgirl can barely survive marathon practice before her body starts acting up, and the school's public health doctor decides her condition calls for some very hands-on practical teaching. What begins as a clinical assessment spirals into mutual oral worship and a raw, sweat-drenched lesson in exactly what a futanari cock can do — until the trembling student finds her nerve and demands her turn on top. Packed with enormous chests, gym-class bloomers, and a teacher-student dynamic where the power keeps flipping, it's a dickgirl-on-dickgirl romp where the only thing being graded is stamina.
