The following sets were timed, backer-exclusives from the artist's Pixiv FANBOX account during 2023.
If it seems like the sets are out of order, they're not: the artist sometimes will go back and redo some of the sets with lactation and/or pregnant variations. If there are any duplicates, please let me know.
433 - 442 and 559 - 570 were samples of the C102 doujin (/g/2666979/3d3d7afe8d/). 629 - 648 is Yomena from Flower Knight Girl.
[Edit (08/25/24)] So it looks like I made a mistake: 017 - 064 are duplicates of 181 - 228 from Part 1 of the 2023 gallery. It's been so long that I don't remember whether it's actually a timed-exclusive or not. While the file size is smaller, the file type and resolution is the same.
