Haruna is terrible at studying but loves sex, and after learning she’ll repeat a year, she worries her smart boyfriend will leave for college alone. A bogus online article claiming men’s IQ drops to three when they cum gives her an idea: make him fail too by constantly draining him with her H-cup breasts. Whenever he opens a textbook, she presses her tits against him, tempts him braless, smothers him with her huge boobs, and wraps his cock tight for one titjob cumshot after another. Day and night, at home and during adult school role-play, the little temptress keeps scrambling her brilliant boyfriend’s brain between her massive tits.
