I'm surprised they hadn't figured out they were doing the deed sooner! I'm loving it.

It has JC sex, so of course I liked it, no loved it.. ;) These lines here, “You know… Every time, with you, it’s just…” He shook his head, “Don’t laugh when I say this,” and she nodded, “I honestly feel like I blow up every time I reach climax with you.” But of course JC, of course.. ;)

I just love Katelyn and JC's hate/love relationship, and I love how you described "position" Katelyn is such a freak, sitting up, yep more fun..lolz

Smart move that Katelyn stopped him to go get grab a condom, haha.

Lastly, Justin, the loud mouth, and all three heads..I can just imagine the looks on their faces.

P.S. Lolz earlier in this chapter, Joey in the bathroom..tee hee.

Awesome job, thanks for the update

Oh my gosh! They did it again! And I loved these parts;

“Well, damn, you look fine!” A whistled from behind her, and she turned around, just as someone’s hand came up, and the hit the owner of the voice. 

“She’s Matt’s sister, dumbass; don’t talk like that.” 

“I don’t give a fuck if she’s Matt’s sister—” 

and 

“Yoohoo, beautiful – tryna shit, here.” 

and

“Oh my god!” Justin’s voice sounded into JC’s ear and he twisted his head to look over at the entrance to the living room. Justin was staring right over at JC, along with the other three’s heads around him. “I should have known when you said you were just going to grab your phone.”

I can't wait for your next update!

Awww! I really liked how the guys made her feel better by singing her the "Barney" theme song! I loved this part:

“Bitch, it’s PopOdyssey, not SobOdyssey.”

And I liked how JC wanted to buy that dress for Kate. I also liked how you incorporated Avenged Sevenfold into the story!
