I'm not exactly sure how to model paper that is "wet".  I think a
numerical approach to some viscous fluid flowing via capillary action
within a fibre based substance would be required.  On the other hand an
exact model is rarely required for artistic purposes and maybe just a
grey region around the water puddle would suffice.
