[25 minutes of exclusive bonus footage included] 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 she trembles and climaxes from her nipples just by being massaged with slippery oil. Finally, on the last day, her nipples, which have become even more sensitive, are carefully caressed and her pussy becomes soaked in no time. She gets out of breath just from a titjob, 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. [Limited bonus video] Asuna Kawai in a risque bikini has her proud breasts squeezed. Licking, sucking, flicking the tips... squeezing a dick between her soft breasts... enjoying her divine H-cup breasts to the fullest.
