I don't own Alvin and the Chipmunks. Sorry. I will own my OC's once they get put up though.

Prologue

"You're like my favourite kind of cake." Theodore mumbled as he and his girlfriend Eleanor kissed in the kitchen. They had just returned from a romantic dinner at their favourite restaurant.

"You're sweet, gorgeous, and every time I smell freshly made pumpkin pie with whipped cream I think of you…"

Meanwhile at the library, Simon and Jeanette were finishing some university work. "So in conclusion, the equation for finding out the product of two integers is "A" multiplied by "B." Simon explained to Jeanette, who was copying down his words into her notes. When she finished she gazed up at him with her bespectacled violet gaze. "I wonder what the equation for love is." she mused.

"Hmm." Simon thought. "Maybe…Boy plus girl? No, that's not technically correct… Maybe the age you hit puberty multiplied by the number of hormones divided by pi? No, that doesn't sound right either!"

Jeanette turned his head so that she could stare into his sapphire blue eyes. "What about me plus you?" she murmured. Her breath chilled Simon because it was cool and icy from the vanilla-spearmint gum she loved.

"Oh yes." he smiled, kissing her. "You and I definitely equal love." Then he surprised Jeanette by sweeping her off of her feet. She gasped in surprise, then they started to laugh, not even stopping when the librarian put a finger to her lips and hushed, "SHH!"

Simon and Jeanette may have had IQ's higher than Einstein, but when they were together, they were fools in love.

At that exact moment, Alvin and Brittany were finishing up a duet in the recording studio. After they sang the last few notes, the producer spoke. "Okay guys, that's enough for today. We'll pick it up tomorrow at 10:00 sharp." Then he turned off his equipment and left, leaving the two chipmunks alone in the studio.

Alvin hung up his headphones and entered Brittany's cubical, where she was putting her headphones away too. She looked his way when he entered and smirked sexily. "Oh my." she pretended to gasp. "Is it just me, or did the room just get so much hotter?"

Alvin grinned and wrapped his arms around his girlfriend. "I almost called the fire department when you were singing because you were on FIRE! I'm so proud of you Brittany. This album's gonna be number one in the charts. I can feel it!"

"Thanks baby." Brittany gently caressed Alvin's face and gave him a kiss. Alvin kissed back, but a bit more fiercely than Brittany. "Your voice was really strong today. Did you gargle with lemon juice like I suggested?"

"Yeah. I almost threw up though. It was so sour." Alvin shuddered, and Brittany laughed at his puckered up face. "At least it didn't turn you into a sour puss."

They both laughed in unison and kissed again. Ever since they had started going out, their arguments had become fewer and fewer.

"Hey Theodore, do-" Eleanor asked.

"You-" Jeanette inquired.

"Love me?" Brittany demanded, running her fingers through Alvin's hair.

The boys nodded at their girlfriends. "Yes. I love you." They all replied in unison.

"You are as sweet as a cupcake." Theodore complimented. "You're intelligent and stay true to yourself." Simon told Jeanette.

"You're the most beautiful girl in the entire universe." Alvin said to Brittany.

"I promise I'll never leave you." All 3 Chipmunks told their girlfriends.

The very next day, the Chipettes never saw the Chipmunks. They assumed that their boyfriends were busy. "We'll see them tomorrow." Eleanor reassured her sisters.

But a year later, when Brittany gave birth to quadruplets, Alvin, Simon, and Theodore had still not returned.
