Rachel Korine shows breasts in last nights season finale of The Knick on Cinemax. Right around the ten minute mark scene opens with her riding her john. We see her breasts bouncing for a second or two until they are interrupted. The views aren't very good in clarity. After her john is assaulted we get a straight on shot of Rachel standing with great views of both breasts. The season finale is available on Cinemax on demand service MAX GO.
