What is the ruling if a young woman nurses two times from an older woman while asleep, and the older woman awakens and completes the required three additional nursings?

Primary text

Since the invalidation results from the joint actions of both women, the financial liabilities are apportioned. The husband owes the older woman her full dower. He must seek recovery of three-tenths (3/10ths) of the younger woman's dower from the older woman, and five-tenths (5/10ths) of the younger woman's dower from the younger woman herself, if consummation with the older woman had occurred. If no consummation occurred with the older woman, he owes her half her dower, and must seek recovery of five-tenths (5/10ths) of the younger woman's dower from the younger woman.
