An intensely fetishistic work where the beautiful mature woman, Reiko, is challenged! Reiko, dressed in a mysterious workwear outfit, has edible oil applied all over her body by a man with a brush. Despite being inserted with a vibrator into her vagina without changing her expression, her enduring demeanor inexplicably excites. The brush moves from her chest, under her arm, through her cinched waist, and to her vagina where the vibrator was inserted. Without mercy, her clitoris is also teased with the brush tip. Making lewd squelching sounds, it continues to tease the beautiful mature woman's lovely vagina!
