Rui Miyamoto works as an executive secretary at a startup, with a spectacular 94-centimeter G-cup bust, narrow waist, and full ass. Her first overwhelming orgasm experience escalates through immediate penetration, restrained sex, drug-fueled sex, and a four-person scene with four cocks. Given no time to recover, she arches, convulses, screams, and collapses under nonstop stimulation. The stunning secretary loses all concern for being seen as pleasure overwhelms her again and again, creating a ten-hour porn spectacle packed from beginning to end with extreme climaxes.
