Poseidon can't help but notice what a fine fish tail Jessie Walker now has. For the first time in a millennium he felt his divine member grow hard. So Poseidon used his godly powers to teleport her to his underwater sea harem.
After the rest of the Olympic games, Poseidon would teach her how to pleasure a god. She would have to learn fast... That is, if she doesn't want to be turned into a complete fish...
Anyway, on with the games!
