[Ponsuke] Officially Accredited Sex Boot Camp Ch 1-5 [flash11]

A rigorous curriculum of pleasure unfolds across interconnected chapters, where eager students and experienced instructors push each other's stamina to the absolute limit. From Rin-chan's breathless surrender as she's pinned to the sheets begging for more, to Kazuto's relentless devotion between a woman's thighs, each couple discovers that the real test is seeing how many rounds they can survive. When one partner gasps that they're ready to go again because it simply feels too good, the boot camp's true lesson becomes clear: nobody here is graduating until they're completely drained.
