The lizard is sitting on a gangway by a lake or a pond, probably preparing to go swimming.
More specifically, this creature belongs to a race from Heroes of Might and Magic III, called lizardmen. Quite a rare species, unfortunately, I could hardly find any fan art, let alone yiff.
I did not specify the gender so you can see it either way. What would you say of it?
It's an old drawing, one of the first in its class.
