Sheldon knew what he had to do.

He knocked on Penny's door. Nine knocks, three Pennys. He waited. She opened the door and smiled.

"Hi honey. Wanna go for a bus ride?"

His eyebrows twitched as he thought about it. "Maybe later. We have something to discuss."

"Oh?" Penny held the door open and allowed him to enter. "What should we discuss?"

"After careful consideration, I have decided that to save both our jobs and to avoid getting criminal records, we should cease the war. I propose we do so by Peace Treaty."

Penny narrowed her eyes.

Sheldon swallowed. "In exchange for you continuing to be my girlfriend, I will allow you unrestricted access to my room."

Penny raised her eyebrows. "Let me get a pen and paper, you're going to want to write all this down. And sign it." She added. He wasn't wigglin out of this treaty, never mind the fact that becoming his girlfriend was kinda the goal all along.

He nodded and wrote down his request on the paper.

"I have some terms too." Penny said. "In exchange for unrestricted lunch time and after hours access to your office, I will wear the slave costume once monthly."

"Twice." He countered.

"Deal." She nodded, and he wrote down her terms.

"Sex in the laundry room is to be restricted to times when either of our abodes is occupied by friends and/or relatives." He stated.

"All kinds of sex?" She questioned.

He blinked. An image of Penny on her knees floated through his mind. "No."

"Agreed." Penny smiled. "But I still reserve the right to do with you as I will in your bedroom even when others are in the apartment."

He thought of all the times Raj had made out with women in the living room chair, all the times Leonard had broken the 72 hour advance notice rule...

"Agreed."

With a flourish, they both signed their names on the bottom of the piece of paper.

"You know, if you learned to drive, I'd be able to give you a blowjob while you were driving." Penny murmured.

He raised an eyebrow. "Does driving a simulator count?"

"I'll think about it." Penny promised.

"You know," Sheldon copied her pattern of speech, "If you got your engine checked, I might be persuaded to..." He held up three fingers and smiled.

"While I'm driving?"

"Stuck in traffic?" He offered a compromise.

She raised her eyebrows. "I'll call a garage first thing in the morning."

He smiled. "We'll need another copy of this, and perhaps we should laminate it."

"You have a machine for that right?"

"Of course!"

When they entered the apartment across the hall, silence fell. Three pairs of eyes stared at them tentatively.

"Whatcha doin?" Leonard said carefully, his voice a trifle high pitched.

"Making a copy and laminating this." Sheldon replied, waving the paper in his direction.

"What's "This"" Howard asked warily.

"A peace treaty." Penny smiled.

"So, the war's over?" Leonard smiled.

"Yes, we thought it best to end it before we wound up in jail." Sheldon said.

"Or jobless." Penny added.

"So does that mean, you two are, over?" Howard and Raj both leaned forward to hear the answer.

"God no." Sheldon exclaimed. "It merely means that we now have accepted guidelines and rules and no longer have to try to out-do each other at every turn."

Raj whispered in Howard's ear. "Yeah, I don't get it either." Howard replied.

"It means knock on closed doors." Penny smirked. "Speaking of which, I think I'd like to go look at your room now." She smiled up at Sheldon.

He looked startled. "Why?" When her eyebrow twitched, his eyes widened, and he nodded. "Ah, yes, well. Goodnight Friends and valued acquaintance."

Penny grinned as she pulled him into his room. "Lets put on some music and lock the door."

"Ok." He did as she asked and then turned to find her sitting on his bed provocatively, smiling at him.

"Oh look." She whispered innocently, "We haven't done it HERE yet."
