Again, I wanna thank all my readers for reading my stories! YOU GUYS ARE AWESOME! Now read on! Pairing is AlvinxBrittany, CGI Version!

'No…. not now…. Why did it I forget?" she asked herself as she looked at her reflection. Her pink pajamas were tossed onto the bathroom floor. Groaning inwardly, she let her eyes look over her furry body. Her auburn colored hair was a mass, a problem that normally would be larger than life itself, but today was different. Much different.

Eyes widening, she stared at her chest. The fur that usually covered her breasts was shorter and thinning away, revealing small, light pink nipples beneath. She let out a tiny yelp as her sight fell upon her crotch. Her slit was slightly open and dripping.

'I'm… in heat…' she thought to herself.

A sudden knock on the door snapped her out of her thoughts.

"Brittany! Let me in!" a voice shouted.

"Hold on!" Brittany shouted back. Leaping off the counter, she grabbed her clothes and quickly threw them on. She hopped onto the handle and pushed down, opening the door with ease as she landed evenly on her four paws.

"OH my God Britt, a guy can hold in his pee for so long!" a red clad chipmunk grumbled, his legs crossed tightly.

"Shut up Alvin. I was busy." Brittany replied, walking pass Alvin with her tail held high.

She made her way into the room shared by her, her sisters, and their counterparts. Climbing onto the top bunk of a triple bunked bed, she groaned and plopped down, face first, onto her pink pillow. "This sucks!" she screamed.

As she lay down, a sweet scent began to fill the air, followed by a sharp pain in her groin, forcing Brittany to double over. Struggling to breathe, the Chipette peeked over at the five other beds, sighing in relief as she saw them completely empty. "Alright…. You win…" she whispered as she laid onto her back.

She spread her legs apart and started to rub her inner thighs, quivering in excitement as her vagina started to leak more of her sweet juice. She let out a quiet moan as her paw touched her swollen nether lips. Her finger slipped inside and sank deep within her pussy, forcing out a long moan. "Oh God…." She moaned as she reached beneath her pillow. She grabbed a chipmunk sized dildo and placed it at her entrance, panting quietly as she pushed it inside her.

Outside the room, a certain red clad chipmunk was striding by the room when a sound reached his ear. A moan, quiet yet loud at the same time. He sniffed the air, sighing as a sweet scent filled his nostrils. He grinned and walked into the room and blushed madly at what he heard.

"A-Alviiin…." Brittany moaned from her place on the bed. She was shoving the dildo faster into her pussy, biting her lip softly with eyes shut tight.

Moving as quietly as he could, Alvin crawled to Brittany's bunk, watching as she moaned his name. 'Oh God… This is so hot…' he thought as he crawled closer to her.

Brittany was completely lost in her own pleasure and scent to notice Alvin creep closer and closer. She moaned his name again as her paw began to rub her sensitive clit.

"Havin' fun Britt?" Alvin asked, wearing a wide grin on his face.

Brittany's eyes opened up faster than lightning as she let out a shriek. "H-H-Holy crap!" she screamed, blushing a dark red beneath her fur. "Alvin?! What the hell are ya doin' here? Can't you s-see I'm busy?" she shrieked.

He simply ignored her and pulled the dildo out of her stretched pussy. Smiling, he pulled her into a kiss and pulled off his shirt. "Of course I know you're busy… I just wanted to please my most favorite girl in the world." He whispered.

The Chipette blushed and shifted onto her belly. "W-Well I do need help…." She replied, lifting her tail slowly.

Alvin got onto all four of his paws and began to lick her pussy from behind, moaning as her juices coated his tongue. He rubbed her tailhole with one of his fingers, grinning to himself as Brittany moaned louder.

"O-Oh my God…. Please don' stop Alvin…" she begged, pushing her rear end onto Alvin's finger. She started panting and clawed at her pillow as pleasure shot through her tiny body. "I'I'm not gonna last long…." She panted, moaning louder with each passing second.

"Hmm… now we can't have you cumming too early, now can we?" Alvin said as he pulled away from Brittany's rear, making her groan as the pain slowly crept back inside her.

"C-Come on Alvin… don't tease me like this.. I need to cum…" she whimpered, rolling onto her back and staring into Alvin's amber eyes. "Please continue…" she asked, spreading her legs as far as she could.

Alvin simply laid on top of her, rubbing the tip of his throbbing member to her pussy. "I also can't stand to see such a pretty face in pain…" he whispered, nibbling on Brittany's neck. He started to rub her inner thighs with his nimble paws, gaining tiny squeaks from the Chipette below. "Of course… I do like it tight and wet…" he said.

She started to buck her hips forward, trying to get Alvin's cock inside her. "I said don't tease…. Ya stupid furball…" she groaned.

"And I said that I like it wet, ya dummy head." Alvin replied, smiling and kissing Brittany's forehead. She blushed softly and licked Alvin's cheek lovingly.

"Please don't make me have to beg ya Alvin. You know how I can get if I have to beg." Brittany threatened, unable to keep a playful smile off of her face.

"Aw shucks… very well then, but I'm not gonna hold back like I did last time." Alvin said, winking as he pushed his cock deep inside Brittany, not worrying about hurting the Chipette. Her barrier had been broken many weeks ago during their first session.

"G-God! It's so big!" she screamed as her tight pussy caressed his length, squeezing and milking out his warm precum. She grabbed Alvin's ass with both paws and groped it roughly, moaning at the top of her voice as the male began to ram his dick in and out of her sensitive nether lips.

Letting out a loud moan, Alvin started to suck on Brittany's right nipple, making her scream his name as her eyes closed tightly. His paw began to rub her other nipple as he picked up his pace, thrusting even deeper into Brittany's cavern.

Back in the dining room, everyone sat around the table, waiting for Alvin and Brittany to arrive. "What do ya think is takin' them so long?" Theodore asked, looking at the stack of waffles on his face, trying not to drool.

"Maybe their busy fucking each other's brains out again, and are gonna come in here pretending that nothing happened." Simon joked, chuckling a bit.

"Now that's absurd. Those two would never get that close to each other." Dave laughed, rolling his eyes.

"Well if they don't hurry up with whatever their doing, Theo's gonna eat all the food." Jeanette added.

"I've got this. ALVIN!" Dave shouted.

His ears perked up quickly as he let out another moan, his climax drawing nearer. D-Do ya think someone i-is lookin' for us?" he asked Brittany, pushing inside her as deep as he could.

The Chipette moaned louder and shook her head. "T-They're too busy eating!" she replied, panting as her pussy began to leak like a loose faucet.

"ALVIIIN!" came Dave's shout again, this time louder and much more impatient.

Alvin ignored the call again, pulling Brittany even closer as he howled in bliss. "I-I can't hold it in Britt!" he whined.

"N-Neither can I! I'm gonna cum!" Brittany shouted as her pussy tightened once more in orgasm, gushing out her cum in thick waves.

"ALVIIIIIIIIN!" Dave screamed for a third time, making the four chipmunks at the table cover their ears, wincing in pain.

"AAAH! I'M CUMMIN' DAVE! I'M CUMMIN'!" Alvin screamed as his cum spurted deep inside Brittany's womb, filling it with his seed almost instantly. He moaned loudly and held on to Brittany as his hot cum continued to shoot into her womb.

Brittany lay limp, shuddering in bliss as Alvin pulled out of her cummy pussy "L-Let's wait until w-we can feel our legs again before w-we go…" she suggested, pulling Alvin into another passionate kiss.

He only nodded and broke their kiss, licking Brittany's lips. "Ever wonder if they expect us to be this loving?" he asked.

"D-Don't be ridiculous Alvie… we're such good actors, they'll never notice a thing." Brittany replied.

*One month later*

"ALVIIIIIIIIIIN!" Dave shouted as he held the slip of paper in his hand. It was a small note that read "How would you react if there were more, much younger, chipmunks? Signed, Alvin Seville."

"Well it looks I was right, yet again." Simon sighed, pushing his glasses onto his face.

Back in the bedroom, Alvin and Brittany lay in Brittany's bed, cuddling as close as Brittany's large belly would allow them, snoring peacefully.
