A/N: It's November! You know what that means? NaNoWriMo. So forgive me if I seem to slow down on updates. I might forget. But reviews will help me remember!

Cas knocked on the door to Dean's room, he hadn't seen Dean anywhere else on campus so he was hoping to find him here. It was time for their tutoring session and Cas didn't have a lot of time available to search Dean out before he needed to go and work on his own homework.

Cas let himself into the room when he heard Chuck's muttered "Come in!"

The room was Dean-free.

"Where's Dean?"

Chuck shrugged, eyes still firmly fixed on his computer. Cas let out a sigh and turned to leave, pausing when he spotted Dean's brother perched at the other desk in the room.

"Sam, right?"

Sam looked up and nodded before returning his attention to the book in his hands.

Cas bent a little to get a look at the cover and snorted, "Dante?"

Sam glared up at him, "What's wrong with Dante?"

"Isn't he a little out of your reading level?"

Sam's eyes narrowed, "I'm sixteen, I'm not an idiot."

Cas held up his hands in surrender, "Was just curious. The Divine Comedy is one my favorite books."

Sam raised an eyebrow. "Oh yeah? What's your favorite cantica?"

"Paradiso. Something about Dante's depiction of Heaven is really fascinating to me, you know? And yours?"

"Inferno. I find the description of Hell pretty awesome. What about Purgatorio?"

"I don't like the idea of Purgatory. Most people forget it exists, anyway. Well, until it's convenient to remember it."

Sam giggled. "Yeah, I guess. I think it's a Catholic thing. I don't understand how these souls can be purified, but not the souls in Hell."

Cas shrugged. "Don't ask me."

"What's your favorite sin?"

"That's an odd question..." Cas sat down on Dean's bed, across from Sam, pondering. "I guess lust? I always liked the phrase Dante used to describe the lusters. 'Carnal malefactors'. Plus, it's something we're all guilty of. The other sins are less natural."

Sam rolled his eyes. "You sound like Dean. He is the walking depiction of lust. I think he gets turned on by everything. And he's a glutton. For pie. And probably guilty of heresy. And anger. And greed."

"Yeah, he's a real winner."

Sam smiled at him. "I'm surprised you put up with him."

"I am, too. When he really pisses me off, though, I just get revenge on him."

"Yeah! It feels good, doesn't it?"

Cas smiled back. "Totally. Got any tips? What things annoy him more than anything?"

Chuck chimed in, "I'm not hearing this."

"Let's see... He hates it when you make fun of his music or his precious car. And, uh... He loves pie more than life itself, and will hate you if you don't share. You never want to question his manliness, or anything like that. Never imply that he's stupid... Aaaaand he's really ticklish."

Dean apparently chose this moment to show up, and Cas couldn't help but smile at him mischievously. "Hey Dean. Did you forget about our little get-together?"

"Are you in here corrupting my poor innocent brother?"

Sam gave Dean a sly look. "I'm far from innocent, Dean."

"You heard him, Dean. We were just discussing some classical literature that you probably know nothing about."

Dean narrowed his eyes. "I bet I do."

Sam scoffed with a smile. "No way. This is way beyond your reading level, Dean."

Cas watched as Dean grabbed the book out of Sam's hands. "Dante? He was one of the Ninja Turtles, wasn't he?"

Cas and Sam just laughed.

Dean glared at them both. "Screw you both."

Cas looked over at Sam, "Remember that last thing you said, Sam?"

"Yeah?" Sam gave him a quizzical look.

"Wanna show me where?"

Sam just laughed, "Yeah, sure. I'll need your help, though."

"Alright." Cas glanced over at Dean. Dean glanced at Sam. He knew something was up.

"I don't like like those looks... What were you talking about?"

Sam just shouted "Go!" and tackled Dean to the floor. "Grab his hands!"

Cas pinned Dean's hands above his head, and Sam began tickling Dean under his arms. Dean started giggling.

"Stop it, Sammy!"

"And he's especially tickling here." Sam tickled Dean's kneecap, and behind his leg. Dean began to squirm and giggle harder and at a higher pitch.

Dean managed to spit out between gasps and giggles, "I'm gonna kill you both."

Sam stopped, figuring he had enough, but Cas continued to hold his hands down.

"Wow, you were right Sam. Looks like he gets turned on by everything." Cas motioned down to the obvious tent Dean was sporting.

Sam backed away. "Dude, sick."

"I'm gonna kick your ass."

"You should probably let him go, Cas... He likes that too much."

Cas released Dean's hands, and helped Sam up.

Cas stared down at Dean. "You can just lay there until your little problem goes away."

Dean glared some more. "Man, shut up."

Sam laughed, "We can leave the room if you want to take care of it."

"I hate you both."

A voice rose from the computer, "Please don't leave him in here."

Cas grinned over at Chuck, "It's only natural, Chuck."

"Especially with Dean," Sam added.

"I think you forget who his roommate is. I'm well aware of his 'natural' problems."

"Can we stop talking about my dick, please?"

Cas just stared down at Dean."Anyway, sorry to bother you guys. I only stopped by to get Dean. He seems to have forgotten our meeting."

Cas reached down, and helped Dean up off the floor.

"Might want to let him take a cold shower before you take him anywhere," Sam snarked.

Dean glared at everyone. "Oh, you guys are fucking hilarious. Come on, Cas. Let's go."

Cas ushered Dean out of his room, and headed back to Cas' room.

"So, Cas... Mind explaining what the hell that was back there?"

"Nothing."

"Didn't seem like nothing."

"Your brother and I were just bonding. Sharing stories and what not. Wouldn't have happened if you were on time."

"Oh yeah, because I can't wait to learn about Calculus outside of class. Totally the highlight of my week."

"You seemed pretty excited about it in your room."

"God, would you let it go?"

"I would... but it's pretty hard." Cas laughed loudly at his own corny joke.
