Her firm, large, milky-white breasts and sweet yet lewd lips become daily outlets for his arrogant lust. Their neighbor, who has been secretly watching them, becomes obsessed with her. Driven by twisted desire, he begins to torment her, until finally her husband sells her off. The greedy, throbbing cocks of multiple men defile Azusa, making her big tits tremble as they use her body.
