The scene opens with a description of the swimming girl's pectoral muscles, which are the muscles that hold her chest and buttocks together. The girl complains that she's weak against the stimulus of the massage, and that the man who's been working on her has been giving her too much of a push. The massage continues, and the girl complains about how much the man is jerking his fingers. The man tells her that he'll treat her the next day based on her results.
