I own nothing. Enjoy!

(This one was a little shorter than I planned, more soon! Thanks for sticking with me 3)

Now that the haze had subsided Sheldon felt a wave of panic wash over him. What had they done? What was going to happen? How would Penny react?

He assessed her expression, but she just looked like she was about to fall asleep. Her eyes were half closed and her breathing still slightly irregular.

His doubts caused a familiar drop in his stomach. Woman were complicated and fickle creatures.

Feeling exposed he frantically searched for an exit plan. As if sensing his panic Penny looked at him concern playing in between her brows.

"You okay, sweetie?" Penny asked softly.

She watched as his eyes darted from her to the bedroom door and back again. Without answering he bolted up grabbing his pants to cover himself and running for the bathroom.

"Well that's a first," she said softly to herself, but it was definitely not unexpected. So how was she going to fix what her sex drive had wrecked?

Rolling to sit on the edge of the bed she felt how weak her body was. Her knees were shaky and every fiber of her being wanted to remain in this haze.

Getting to her feet she looked for her clothes. She saw Sheldon's black shirt crumpled and picked that instead, throwing it on and making her way to the bathroom. She tried not to be offended to find that he had the hot water full blast as steam hit her in the face.

"Sweetie, maybe we should talk..."

"Talk?!" He exclaimed sounding slightly muffled by water. "No, we should definitely not talk. Talking cements the reality of what just happened."

"Look, you have an eidetic memory. Do you really think forgetting is going to be possible?"

"No, but I can try!"

Penny felt a wave of disbelief wash over her. After everything that had happened the last week he just went right back to his insane self. Acting on impulse she pulled his shirt back over her head and ducked into the shower.

Sheldon was frantically scrubbing his already red skin and was shocked to see Penny standing boldly behind him. He moved to cover himself in horror as she rolled her eyes.

"Penny!"

"I've already seen it all, sweetie, there's nothing to hide."

"You can't be in my shower while I'm showering!" He asserted.

She closed the distance in the already cramped shower. Water cascaded over her as she moved forward, backing him up until he was pressed against the shower rack. He searched for an exit again and she almost felt bad.

Almost.

"Why not, sweetie? Looks like you could use a hand." She reached down between them and cupped him intimately.

He relaxed subtly leaning into the touch. Penny looked around and grabbed the bottle of soap and squeezed some into her hand.

Rubbing her hands together she began spreading the soap against his chest massaging softly.

"What are you doing?" He asked trying to sound stern but the fight was leaving him. Penny felt conflicting urges rise to the surface. One wanted to bolt, the other wanted to continue for hours on end.

"We're continuing your experiment," she replied sliding her hands over him.

His eyes drifted shut, giving Penny a clear green light. She slid herself against him and took his bottom lip between hers. His hands drifted over her body sliding over the wet skin and driving Penny back to new heights. Her back hit cold tile, bringing her back to her original motive. She stopped the kiss, pulling back and moving to pick up the abandoned bath pouf.

"Will you wash my back?" she asked as sweetly as she could.

"Will I… what?"

"Wash my back," she affirmed turning her back to him.

Sheldon stared at the naked blonde that had invaded his shower and his senses. First she attempts to seduce him and now she wanted him to bathe her. Was this normal post coital behavior?

Of their own volition, his hands took the soapy item and began to rub it against her shoulder blades.

"I have no idea what I'm doing," he confessed, though he didn't remember planning to do so.

"You're a genius. I'm sure you'll figure it out."

"My aptitude and intelligence are reserved for a particular subject and that subject is Physics."

"So you don't know how to scrub a back?" She turned to meet his eyes. "It's pretty simple, but if you can't..."

"Of course I can, it's just a matter of whether or not I'll do it the way you like."

"I'm sure I'll like whatever you do," she remarked turning away.

Her tone revealed her innuendo and Sheldon felt himself swallow a little harder than he meant to. Focusing on scrubbing her shoulders his eyes wandered the curves in front of him. His hands drifted over them automatically and he found that somehow this simple process was making him aroused. As his gaze found the familiar, but somehow different tattoo on the curve of her posterior he found his hands on her hips drawing her backwards.

Penny leaned forward when he pressed against her and pressed her hands against the opposite wall of the shower. It was quite a stimulating scene. Furthermore, it would allow him to…

Penny gasped feeling Sheldon enter her again. This time it was a bit easier to handle, but it was still surprising. How had he hid that for so long? Then again, she hadn't exactly been looking. When he began thrusting it canceled out any other ideas she had. He began moving faster and harder, his fingers gripping her hips and their moans echoing against the walls.

It wasn't long before she was orgasming for the second time that night. Moments later she felt him push hard against her signaling his own end. Shakily she turned to face him and he semi-collapsed against her pressing his face into the curve of her neck. The feel of his lips in that sensitive place caused a foreign feeling in her stomach.

"What on earth has gotten into me?" He asked softly.

"I don't know," she replied letting her hands trail over him. "But whatever it is, I have it too."

There was a tangible silence and Penny almost made a run for it. This was happening to fast and if she didn't know any better she'd describe this feeling as falling. She moved around him leaving him leaning against the corner with his elbows.

She washed off quickly a slow sense of awkwardness permeating the air. She had acted on impulse and now she was feeling things. Things she should not feel.

She stepped out grabbing a towel from the cabinet and drying herself off. Going through the apartment she put away the pizza leftovers, turned off the lights and washed the dishes. Anything to stay busy. As she put away the last dish Sheldon came into the kitchen wrapped in a towel. Her heart responded by quickening.

He met her gaze and she saw her own terror reflected there.

"Okay," he said slowly. "I'm ready to talk."

"It's kind of late to talk," Penny walked around him to the bedroom. "Why don't we go to bed instead? We'll talk in the morning." The false cheerfulness of her voice sounded shaky as she searched for her clothes. She turned to leave but he was in her path.

"I'm sure both of our REM cycles have been interrupted for the evening already."

"Maybe we can salvage them." She avoided his gaze.

"Penny, you're wearing my shirt."

She looked down at the shirt. Twice she had casually thrown the item on. It was familiar and soft against her skin.

"It will serve well as pajamas I suppose." He remarked before walking around to get into bed.

Her surprise must have shown because he went on.

"I have been trouble sleeping. Maybe the company of a friend will help."

Penny walked to slide in next to him. Facing Sheldon as he shut of the lamp, she tried to curb her anxiousness. He came back to face her as well. They lied there for a moment Penny searching for something to say, but he spoke first.

"I think if we're going to establish a pattern we should assume the same position as before. Otherwise I'll never get any sleep."

To Penny's surprise he laid on his back and put his arm over her head. She moved in closer and found her anxiousness shift to … something else. She had her head on his chest and it just felt so good. The warm and clean smell. This wasn't a hook up. It was different. Terrifying. Wonderful. Odd.

She felt the warmth lulling her into sleep but she had to say what was on her mind.

"Sheldon," she murmured.

"Hmmm," he groaned.

"Thanks."

"Hmmm?"

"For letting me stay, thanks."

There was no response and they both drifted off.

Please Review! I love hearing good things. I'm starting the next chapter right now.
