UPDATE: Link was broken before, now fixed.
If you read the captions of the associated image-story, the giantess here caught the shrunken woman cheating with her (the giantess’s) boyfriend and shrunk them both.
Those eyes, she’s trying to figure out her next move. Plotting to escape maybe? Or perhaps just trying to think of a way out of having to touch that dick?
A particularly cruel giant might tune the temperature in the room down so low that their tiny pet would have to snuggle and rub up against that massive cock for wormth~!
