The following sets were timed, backer-exclusives from the artist's Pixiv FANBOX account from early-November to the end of 2022.

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.
