Hmm it must be the work of fingers! Look at the first page how she has both arms placed, they look to be either trying to cover up herself or pushing a certain hand away from that spot. In the next sections there's an up and down motion with her body, and after coming there's the squeeze. Also before the colored paged you can clearly see an arm between the legs.
I probably imagine that this whole thing started with actual tickling, hands moved around the legs, up to the thighs and then situated themselves between the legs. And that's where this whole thing started.
Also i think if this was ever the work of a toy, i don't think it would deserve it's title. So that's why I believe it was fingers.
