This is my FIRST story, so it might not be too great. Anyway, It's about the chipmunks as they were in the 2007 movie. I don't own Alvin & The Chipmunks, but I DO own CJ The Chipmunk.

"Well," said Dave to Simon, as he usually leaves Simon in charge, "I'm going to the store. Simon, make sure the others behave."

"You got it, Dave," said Simon with a smirk, hurrying Dave out the door.

Being the smart/ responsible one, Simon goes to check on his brothers, hoping for ONCE that Alvin was just doing something "productive", a.k.a, something good.

"Ted, you okay in here?" Teddy was sitting in the den watching somethin' on t.v.

"Yeah, just fine Si." Simon smiled

"Okay, just checkin' in."

Now, strangely enough expecting him to be doing something good, Simon went to check on Alvin. He was laying on his bed listening to his mp3 player.

"Hey, Alvin."

"Hey, Si. You need somethin'?" Alvin said after turning off his mp3 player.

"Nah, just checkin' in." Simon looked around curiously to see if anything in the room was trashed.

"Hey, Si, if you think I did somethin' wrong, come in and check!"

Simon entered the room, and began to look around, checking in the closets, under the beds, the whole nine yards to see if anything was broken and then hidden. Alvin hopped up from the bed, and walked up behind Simon.

"Si, I could help ya, but I didn't do anything." Simon sniffed around a bit more

"Okay, you can help me, I guess."

The room had passed inspection by Simon almost completely, and so he decided to check under all three beds again, while Alvin was sitting on one of them, Simon's backside toward him. Natuarally, Simon had to bend down to check under the bed, giving Alvin a good view underneath Si's clothes. Alvin didn't think anything of it until he realized…he couldn't look away…and he felt his member start to harden. Simon stood back up and walked over to Alvin who was blushing, his member completely erect now, even though he was trying to hide it.

"..Alvin? What's wrong?" Alvin blushed even more, and diverted his gaze to the ground, now noticing that Simon had seen his member.

"Alvin? Are you oka-" he was interrupted by Alvin gathering the courage to stand up, pull himself as close as possible to Simon, and kiss him on the lips.

Simon jerked away wiping his lips.

"Ew, man! Why did you do that?!" exclaimed Simon.

Alvin frowned and looked down, blushing hard, then turned away and laid face down on the bed, as Simon exited the room. He made his way into the living room and started watching t.v., thinking about what had just happened. At the moment in time, it seemed disgusting, but the more he thought about it, the more he realized no matter which way he looked at it, he wanted to do it again. It wasn't something most people would understand, but he didn't care.

Feeling extremely guilty for rejecting his older brother like that, Simon went back in to check on Alvin, who had started listening to his mp3 player once again.

"…Um….hey, Alvin?" Alvin pretended not to hear this, even though he could plainly hear his brother's voice over the music.

"Alvin?" Simon asked again, this time, being responded to by Alvin turning off his mp3 and taking out the earplugs. He walked over to the bed his bro was on and sat close to him.

"Alvin..I'm really sorry about earlier.." Alvin turned away in silence.

"Alvin, I didn't mean to get you upset.."

"Well, you did…just go away.."

"Alvin, please.."

"No."

Out of sadness, frustration, and desire, Simon grabbed his older brother, turned him toward himself, and kissed him on the lips passionately. Alvin hesitated, but couldn't help but to return the kiss and throw his arms around Simon. Caressing each other's bodies, Al flipped positions so that he was on top, and kissed Si, putting their tongues in each other's mouths.

Simon reached up and took off Alvin's shirt and pants, and Al pulled off Si's sweater, but pulled off his pants with his mouth, causing Si to moan. Now they were both naked, and Alvin looked Si up and down, biting his bottom lip from the sight.

"S-Simon…can I blow you?"

"You know it.." Simon bit his bottom lip as he watched his brother go down kissing his body.

Alvin had already kissed all over Simon's body right down into his groin, where he licked Simon's shaft up and down, causing Simon to moan and shudder out of pleasure. Finally, Alvin puts his bro's whole member in his mouth, bobbing his head up and down. It took less than five minutes, but Simon came in Al's mouth, and Al swallowed it all, then came back up to make out with Si.

"Alvin...I wanna taste you.."

Simon kissed Alvin's neck twice, as he rubbed all over him until he got to his groin. He pumped Al's member twice first, then engulfed it and bobbed his head up and down while Alvin moaned from extreme pleasure and excitement. After which, they collapsed on top of each other, and laid there for about five minutes, hugging each other close.

Then, Alvin stood up smiling, and he got on all fours signaling to Simon to go in him. With that, Simon stuffed his member in Alvin, and Alvin moaned from pleasure and pain. The faster Simon humped Al, the more he loved it, and at last they both moaned as Simon came in his older brother.

"Your turn, Si," moaned Alvin

Simon got on his hands and knees, and flinched as Alvin shoved his member in him, going in a fast yet calm in-and-out motion. Simon tried to muffle out a,

"Ohh, Alvin…yess…" but he couldn't help it.

After twelve minutes, Alvin came in Simon, and he pulled himself out and laid on his back, right next to Simon. He leaned over and kissed his brother, then asked,

"We're not going to tell anyone, right?"

"Of course not, maybe Teddy would understand, but…still…"

"Well, can we do it again? Ever?"

"Yes, we just can't let anyone know. Now, come on, let's go get cleaned up and watch t.v."

"Ok. I love you Simon..so much"

"I love you too, Alvin."

The t.v. was left on in the living room from when Si was in there previously, so Si laid on his back on the couch, and Alvin snuggle up with him.
