Warning: This chapter contains mature content other viewers may find disturbing. Don't like don't read. I'm just going with the basics of sex  here. I'm not sure how chipmunks really have sex and I don't really wanna look it up.

Brittany and Alvin had the biggest scene yet to make.

Brittany had taken off all her clothes to surprise Alvin although Alvin had the same idea.

A/N: I feel so dirty writing this.

"Alvin?" Brittany called standing there naked as she crept into his room.

"Brittany?!" He had no clothes on either.

"Guess we have a tie breaker." Replied Brittany.

"guess so.....so....sex now? Not that I'm trying to pressure you but..."

"Yes Alvin. I'm ready now."

Alvin moved forward kissing her roughly on the lips. He trailed his front paws down Brittany's waist on either side. Then moved to kiss down her neck.

Brittany pushed him on the bed then fell on top of him.

Then Alvin said "Should I or shouldn't I?"

"Do. it." Breathed Brittany.

Then he put his (you know. whatever a chipmunk uses to have sex into her I'm guessing a tiny chipmunk penis.)

He thrusted against her harder and harder.

Him and Brittany both started panting then with one final big thrust he pushed his all the way then it came out with a (pop!) noise.

They both lay side by side together gasping for breath.

"I love you Brittany."

"I love you too Alvin."

Then they heard someone clear their throat which was Simon standing awkwardly in the doorway.

"Could you guys like...maybe close your door next time or....."

"GET OUT SIMON!!!"

"Right um ya ok bye!" Simon bolted away.

Simon shuddered. "There's something Ill never get out of my head.

A/N: Well I hope you all liked it cause let me tell ya I felt SUPER awkward writing that even though it was short.
