Sharky and Sif started talking all of the night, as they were enjoying the pleasure.
As they talked, Sif revealed her Asgardian heritage, explaining that she had the potential for a lifespan of thousands of years.
"I've lived only a small fraction of my life; I have so much more of it left to live. Now I want you to live the same long life as me. So I will find a potion from my father, so you may also live a long life."
Sif said as she was caressing his face, and looking into his eyes. She knew Odin loved her, so she believed her wish would be granted.
Sharky smiled and said, "As you wish, Sif." He didn't tell her he was also an immortal now; he wanted to reveal this to her, but since she wanted to do something for him, he accepted it.
