Legendary Hand [Mature]

The doctor explains that he can't perform the special treatment on a woman who has "yin energy" because it's not good for her. He tells her that she can have sex with any woman she wants, but only if she passes on the "yin" energy to another woman. She's so excited that she falls asleep while getting the treatment. The doctor says that if you let "yin blood flow smoothly," it has a "positive effect" on all of a woman's bodily functions. He says that even though he absorbed so much of the yin, he's still getting aroused. He asks the doctor if there's anything stronger than this special treatment, but the doctor says it requires "ultimate skill." The doctor asks if he can tell her what it is, but she won't tell him without the director's permission. She says that she'll get up first, and then she's going to have sex again.
