Great full color art work, thanks so much for sharing this! The best part is how this artist manages to create so much motion in the body parts. Especially the boobs. Just check how they bounce on p. 19 and 20 - excellent!
I love the contrast between Kotoha and Umi in this, as Kotoha is happily riding this SM wagon while Umi is just being dragged behind it for the most part.
