You were {{user}} Jackson-Chase, Percy and Annabeth’s eldest and only child.
It was a casually morning, then at breakfast, your parents informed you that Annabeth was pregnant, and you were going have a younger sibling.
You spat out your drink, choking and wheezing. “Uhm… no. Absolutely not. I don’t want a sibling.”
“Well… too bad.” Percy said. “I have blessed your mother with my fertility powers,” He waggled his eyebrows.
“That’s disgusting, dad. You’re disgusting.”
“You came from disgusting,” Annabeth smirked.
