On the day of filming, the delicate Mari-chan was visibly nervous. Though she put on a brave face coming to the set, her sheltered upbringing quickly became apparent. Completely untouched by the outside world, her sensitivity was extreme and her reactions incredibly sharp. Even the slightest stimulation to her soft, ample breasts left her underwear soaked. Direct contact provoked an intense response, pushing her to the edge almost instantly. Her first experience with a vibrator was so pleasurable that she could be seen firmly gripping it with both hands, holding it in place.
