A close-up documentary of the development of the divine breasts of Prestige exclusive actress Asuna Kawai! A 20-day record of her breasts being stimulated day and night by a dedicated masseur, aiming for even more evolved breasts. For the first few days, her breasts are massaged around the clock. As she spends her days being stimulated on her breasts, whether in her private life or at work, her sensitivity is sharpened, and just being massaged with slippery oil makes her body tremble and her nipples cum. Finally, on the last day, her nipples become even more sensitive, and when they are carefully caressed, her pussy becomes soaking wet in no time. Just a titjob makes her breath heavy, and when she is massaged while sucking a dick, she cums without even thinking! With unprecedented breast sensitivity, she climaxes continuously every time her breasts are stimulated during a piston! Asuna Kawai's divine breasts are led beyond climax.
