"The god of gods, Zeus."
Zeus?! He was turning into Zeus?! Looking at his body, he could see that he was growing thick muscles over his body, and that it was about six and a half feet long. He could feel the beginnings of a thick beard pushing out from his skin. Not bad for a thirteen year old.
"Zeus. But...why? And how?" he gasped. The rings of fire were still permeating his body, but the sensation was starting to feel less painful and more pleasurable.
He looked up to gaze at the gods and goddesses surrounding him. There was Athena, goddess of wisdom, Ares, god of war, Aphrodite, goddess of beauty, and Hermes, messenger of the gods. All had an aura around them, which ordinarily made it difficult for humans to look at them, but he wasn't having any trouble. Furthermore, both Ares and Athena stood naked, showing off their absolutely perfect bodies, and proving that the gods did not play by the humans' rules. The others wore togas, woven from fine cloth.
"It's a long story," Athena said. The gods moved in and knelt down by the still emerging god. "We will wait for you to finish." As Zeus continued to emerge, the gods offered soft words of encouragement. Soon, his thick pectoral muscles stuck out on his muscled chest, and his beard was fully grown. He was taller than even the other gods, standing about ten feet tall. He was able to get up off the ground and crouch down, the soul of Olympus flowing through him. Even crouched down he was taller than his old human body.
Aphrodite rubbed Zeus's back, running her fine hands over the thick, rippling muscles on his back, all the way down to his butt. "How do you feel?" she asked.
"Fine," Zeus said, surprised at the unfamiliar sound of his voice. "I feel so...different. I am a god," he said. The rings of fire that previously were agonizing him were now sustaining him.
Hermes nodded. "That coin you found? We all have them. We were all born as humans and we've all been given those coins to turn us into the gods."
At Zeus's shocked look, Hermes looked around and nodded at his compatriots. They all began to shrink and their muscles began to soften. Soon, they were all shorter than the still crouching Zeus, all in their human forms. "This is what we used to look like, before we were gods," someone said. Surprisingly, Aphrodite was a man, and Ares was a woman. They quickly relinquished their human forms and grew into gods once again.
"Amazing," Zeus said. "But why would someone want to give up being a god? Are you telling me the former Zeus gave me his coin and I took his place? Why would he want to give this up? And why did he choose me?"
The gods had no answer. "You'll probably find out those answers soon enough."
Zeus stood up and drank in his new form. He was head-and-shoulders taller than the other gods, who were all about nine feet tall to begin with. A delicious feeling of warmth pounded through his body, the essence of being a god. He flexed his arms, looking at his biceps which were as big around as grapefruits. His cock and balls were also larger, in proportion to his new body. Surprisingly, he didn't have a lot of hair on his body below his face, his skin was smooth, even around his groin. He even felt around his body at his tight and thick butt.
Ares said, "The gods know when someone new takes over the body of a deity. Usually we try to meet them and aid them. Because you are now the king of gods, four of us came." Ares gave Zeus a serious look. "You have an important job now, Father Zeus. Are you ready to go to Olympus to assume your place as king of the gods?"
