Ripples in Time (Patreon)

Chronoa wanted to put on some pounds, but her impatience led to her jumping through her own past to various points and coaxing her past self to indulge just that little bit more.

Now, though, those past selves are biting back, and Chronoa might end up fatter than she ever dreamed of..!

This is actually based on an old story that's currently on the 'to-do' list, revolving around the same sort of concept.  Maybe this will end up being the ending to that!
