What happens when Kripke releases the uninhibited side of Sheldon?

:Split Personality:

Sheldon watched skeptically as Barry swung the pocket watch in front of his eyes. This would be the easiest $100 he had ever made. Barry was sure he could hypnotize Sheldon. Sheldon was sure hypnotism was pure hokum.

"Owkay," Barry said, once Sheldon was under. "You awe compwetewy under my spwell. I am going to give you special pwompts. The word stamen will pwace you into this state. The word cotton will retuwn you to your usual self. You will wemember evahwething." Barry smiled at everyone around the room, ready to embarrass and humiliate his colleague. "Owkay, Coopah. Open your eyes and show evahweone what you are wike without your phobias!"

Penny's phone began ringing just as she was stepping into the shower. She sighed and checked the number. Cal-Tech? Why would the university call…..Sheldon. Oh yeah, Leonard was out of town. He must need a ride home. Penny hit answer and put it to her ear.

"Sweetie, can you give me 20 minutes?"

"Ms. Queen?"

Penny frowned. "Who's this?"

"This is President Seibert. You are listed as Dr. Coopers emergency contact. You need to come get him."

Penny pressed her head against the wall. "What has he done?"

"Well, it's better if you just come see. I don't think you would believe me if I only told you," Seibert said mysteriously before hanging up.

"Holy crap on a cracker. What the hell have you done, Moon Pie?"

Penny looked open mouthed around the cafeteria. Overturned tables, shattered vending machines, and an unconscious Kripke being wheeled out on a gurney. She looked over at Sheldon, who was looking lost and frightened between two security guards.

She turned to Seibert. "I'll take him home. What kind of trouble is he in?"

Seibert shook his head. "None. This wasn't really his doing. He was hypnotized. Apparently Kripke was trying to play a joke and it got out of hand. I can't really fault Cooper for this, but I do think he needs a days rest." He looked around the room. "Maybe two."

Penny nodded with relief and hurried over to Sheldon. He looked estatic to see her. She was tempted to hug him, but that would just set off his quirks. Instead she lightly patted his shoulder and gestured to the door. They made their way to the car and got inside.

"Thank you for coming to get me," he mumbled.

Penny smiled at him. "Anytime, sweetie. That's what friends do."

The drive was silent. Once they got to the apartment, they checked their mail and began going up the steps. "So, wanna talk about it," she asked.

Sheldon sighed. "I don't. I lost all control, Penny. It was horrible."

They reached the fourth floor and Penny unlocked her door and opened it. "Well, it's over now. You weren't blamed, either. Your boss said it was Kripke's fault. " Penny sighed with resignation. "Why do grown men revert to acting like kids? Why can't they stay men?"

A weird growl made Penny freeze. She looked over her shoulder and fear shot up her spine. Sheldon was looking at her with blazing eyes. His lips were pulled back in a wide grin. He took two steps…no, she thought faintly. He stalked over, and placed one hand on the each side of the door jamb.

He slowly leaned his head down and sniffed her hair. Penny trembled and took a step backwards into her apartment. What the hell? Sheldon licked his lips and moved forward as well. Penny's purse fell from nerveless hands. Never in all the 6 years she had known him, had Sheldon ever looked like this. She could see the lean muscles in his arms tense up. His hips had a fluidity, a graceful glide to them, like a cougar. He grabbed the door and slammed it behind him, without taking his eyes off of hers.

"Shel…Sheldon? What's going on?" she whispered.

He matched her step for step as she backed up to the wall beside her bedroom door. Her back was pressed hard against it and he moved until their thighs brushed each others. His left hand slammed into the wall by her head. His right snaked out and wrapped around the side on her neck, his thumb stroking the rapid pulse on her throat.

He leaned in and licked her collarbone. "I want you," he murmured. "You are mine." Then his lips captured hers roughly and his tongue dominating her mouth. He moved his hands to her hips and he pushed her up the wall so he could settle his erection between her legs. He flexed his hips against her core and Penny moaned.

Penny's mind was pure chaos. This was Sheldon Cooper! Sheldon "Coitus=Germs" Cooper! And he was…oh god! Was he really touching her there?

Sheldon's hands slid her skirt up around her waist as he nipped and sucked on her bottom lip. He curled his fingers around the crotch of her thong and jerked, ripping it apart. He growled with delight as she whimpered and moved against him.

Sheldon moved back far enough to unfasten his pants. He pushed the material out of his way and thrust forward, grazing her clitoris roughly. Penny gasped against his mouth, whether from pleasure or shock, she wasn't sure. His hands dug into the flesh of her thighs as he lifted her up and slid into her. He abandoned her mouth and bit the side of her neck. He pounded into her as fast as he could. She reached for her shirt hem and drew it over her head. Her arms wound around his neck and she tightened her vaginal walls around him. Sheldon growled again And dipped his head to lick and tease her breasts.

Penny screamed his name as her orgasm hit. Sheldon pulled out of her and picked her up. Three quick stride and he tossed her down on the bed. He rolled her over and spread her legs wide. He grabbed her hips and pushed inside again. Penny braced her upper body on her elbows and pushed back against him. They moved in sync, their bodies instinctively finding a rhythm together.

Their bodies glistened with a sheen of sweat, the air filled with the sounds of moans and bed springs. Penny was getting close again when he reached around her waist and shifted their positions. She was on her side, with him behind her. He started moving again, his face pressed into her shoulder.

"So good," he whispered. "So warm, and wet, and mine. All mine."

Penny reached her hand back to grasp his hip and licked her swollen lips. Sheldon was pushing all of her buttons. She was putty in his hands. She scratched at his thigh, urging him on. He bit her shoulder lightly and grinned.

"You like this, don't you?" he asked, his Texas twang prominent.

Penny gasped and nodded. "Caught on to that, huh?"

Suddenly he froze. Penny growled in frustration. This was no time to tease!

"Penny?" Sheldon's voice was timid and shocked.

Penny looked over her shoulder into wide, startled blue eyes. "Sheldon? What's wrong?"

Sheldon licked his lips self-consciously. "Dear lord! Penny I am so sorry! I…I… OH god, what have I done?!"

Penny started to pull away so she could see him better, but stopped when Sheldon's hand tightened and he groaned. His eyes got even wider and he blushed as his hips bucked. Slowly Penny pressed back again, watching him carefully. Sheldon closed his eyes at the pleasure, but guilt still marred his expression. "Sheldon, what's wrong?"

He opened his eyes and looked at her with sorrow. "I have forced myself on you," he whispered faintly.

Penny held perfectly still. "Don't you want me anymore?" she asked softly.

Sheldon looked at her in surprise. "Penny, I …I have … You did not want this. I made you."

Penny gave him a gentle smile and slowly squeezed her inner walls again. Sheldon's eyes went wide and heated up. "Sheldon, if I asked you to stop, would you?"

He nodded fervently.

"If I asked you to keep going, would you?"

He moaned low in his throat. "Yes." he answered, half assertion, half plea.

Penny squeezed again. "Sheldon?" He looked into her eyes. "I'm yours. Don't stop, unless YOU want to. Because I want this."

Sheldon pulled away from her, and moved over top of her body. He watched her closely as he entered her again. Penny sighed happily and wrapped her legs around his waist. He pressed his mouth to her neck and began pumping his hips again. They moved leisurely now, though. Exploring, touching and learning each other's body intimately. This time, when Penny's orgasm hit, Sheldon was right there with her.

They lay on the bed, curled up in each other's arms. Sheldon told her about the hypnotizing, the trigger words (although he spelled them out rather than say them). Penny asked what would happen if someone else said them. Would he want to have sex with them, too? Sheldon shook his head.

"At the university I had no urge for intercourse. Not even with any of the attractive women there. I remember looking at them and being angry you weren't there," he said shyly. "However, to be safe, I believe it would be prudent to have the triggers removed from my subconscious altogether."

Penny snuggled and smirked. "Too bad. I kinda liked neanderthal Sheldon." He looked at her sternly, although there was a hint of desire in his eyes. Penny grinned. "But I'd rather have the real you any day."

Sheldon kissed her tenderly. He would have to remember to thank Kripke, after he removed the triggers. After all, that little prank of Kripke's had gotten him Penny.

For Rene, who said she wanted a naughty version of Encino Man.
