続・色暦大奥秘話　淫の舞 (1972)

The twelfth shogun, Ieyoshi, embraces Oruri day and night under the care of Fujioka, a guest attendant at the O-oku. However, Fujioka's senior, Kumoi, who recommends Oseki to him, is not amused at all. The scene between Fujioka and Kumoi was symbolic of the battle between women in the O-oku. Fujioka hears from Orui that she is pregnant and rejoices that she has nothing to fear if she bears the Shogun's child. Meanwhile, Kumoi comforts Bure, who is a lesbian, and asks Oseki to help her get a call from the shogun.
