An unconventional documentary-style work featuring Asako Mochizuki, eight months pregnant, stripped naked in a traditional Japanese room and bound with hemp rope while her breasts are tormented to capture her reactions. The film depicts her restrained in various positions—embraced from behind around a pillar with arms raised, wrists tied above her head—and shows intense nipple play, with prolonged, powerful scenes of milk expression. The action progresses from M-shaped leg binding to inverted Y-shaped suspension, intensely highlighting the eroticism of the young married woman's swollen pregnant belly.
