These seem to be listed in chronological order on panel 145 https://e-hentai.org/s/2e7a52e5d1/2923267-145 , but I think these are a better read with a few titles closer to publication order, a little like Narnia. As such, I recommend: One Human Being, Grace, good spot to throw in Kinfolk, then Space Trek Fleet Wars, Madiy and Crash, Skybloom, Tentacle, Lithium, and then Bubble as a dessert/reward for all the satisfying emotional and sexy ups and downs. Brilliant work, their collective efforts are such a gift.
