[Shinozaki Rei] St Harukawa Academy's Strange Tales (Mesubuta JK Nikubenki!!!) [desudesu]

At St. Harukawa Academy, a female-dominated school where bottom-ranked boys serve as human toilets in the girls' restroom, a prim, bespectacled schoolgirl sneers at the 'perverts' who volunteer for the job—then decides to put those eager underclassmen to work herself. Her smug composure melts fast as the hairy, big-titted Tatsumi slurps smegma off one cock after another, demands two cocks pumping her pussy at the same time, and begs to have her ass filled too. Months later she's glowing with a huge pregnant belly while classmates whisper impossible rumors about what she actually gave birth to.
