Sherman has recently become trapped in a whale, which reminds me of another time he was also trapped in a whale, but nothing wrong with that.
The storyline starts around here. There isn't any on-panel vore, one day they are trying to get to a coffee place, the next they have steered into the mouth of a whale. The dialog is fun, though, and they've been stuck for several days.
