After the final bell, strait-laced class representative Mizuhara Kazuko stays behind for a twisted private lesson only she and her teacher know about. Bent over the desk, her slender body is pinned as he drives his cock straight down her throat, forcing tears while she gags helplessly. The once-uptight honor student soon loses control—squirting hard from relentless, raw pounding and taking thick creampies until her womb overflows. Beneath her perfect image, Kazuko grows addicted to the forbidden after-school training, sinking deeper into her teacher’s dominance and pleasure.
