That Time of the Celestial Rotation is an explicit twelve-page comic made by the artist PatchYeah. Features a human on anthro relationship between his characters Molly and Pepper. Illustrated from December 2020 to November 2021.

Warning: this contains some things the artist says that "if this isn't your thing" you could "consider it some gross body horror Halloween thing": specifically containing impregnation (interspecies; egg insertion), inflation (belly inflation; egg inflation; and some weight gain), and oviposition of soft-bodied eggs (not the chicken or lizard kind; the goopy frog or fish ones).
