Another theme might be protection. Poseidon could be cuddling Percy to show that he will protect him from the various threats that Percy faces in the Percy Jackson universe. It's a way of showing his fatherly love and concern.
There could also be a theme of comfort. Percy has been through a great deal in his adventures, and a cuddle from his powerful father could be a source of great comfort. It can also show Poseidon's softer side, which is not often seen in the original stories, and give a new dimension to their relationship within the fanfiction world.
