[Wakabatei] Sex Representative {Doujins.com}

A bespectacled class president puts her huge breasts and plush thighs to civic use as the school's official 'sex representative,' starting with a health-class condom workshop where, blindfolded, she serves as the practice hole for a queue of nervous classmates. One by one the boys claim their turn, finishing embarrassingly fast while she sobs, sweats, and takes the full course of their enthusiasm. When the thick-browed homeroom teacher later recruits her to coax a school-phobic truant back to class, this dutiful representative proves no position is off the table for the student body.
