Prologue

"Hey, guys, want to join my gang?" Percy Jackson asked his fourfriends from the 'Big 7': Jason, Leo, and Frank, and their 'companion', Nico.

"What 'gang'? Does it have to do with bloody combat? 'Cause you know I hate having to kill," Leo replied. "I like creating and fixing stuff and bursting into – Oops! Flames –" Leo threw down his shirt and stomped on it. "Well, sorry, guys, for 'accidently' catching on fi –" he stopped halfway and looked at Frank and bit his lower lip, concerned.

"Hey, sorry, man. Really, didn't mean to do that. C'mon, have some of Esther's peach preserves." Frank just nodded his head. He averted his eyes to Percy, for no reason, who was tapping his foot impatiently.

Percy just shook his head and said, "It's the 'BFS' Club." Nico and Jason both raised an eyebrow, making it clear that they were both wondering, "isn't that the 'Best Friends Sing' club or something?" Percy just laughed. "It stands for the "Big Five Sex" Club. Spending time with Annabeth has been quite boring , and I thought we should have sex with people other than our girlfriends." The others all grinned except for Nico, who liked Percy.

"Hey, but…" he sputtered.

Jason smiled. "Dude, it'll be all right. Relax."

And so that was how the Big Five Sex Club started.
