A 20-year-old female instructor with 14 years of karate experience makes her AV debut with a 100cm bust, ready to be expelled. Her karate kata, which makes the most of her 170cm frame, are impressive, and the way her breasts shake when she punches with a straight fist is also impressive. Her innocent big breasts, which have only had three experiences with men, are squeezed to their heart's content, deformed to their fullest, and her innocent heart is shaken by the continuous penetration.
