AN: At long last! LOL. I hope you all had great holidays, mine was busier than heck, but hopefully this little chapter was worth waiting for!

CH

Penny had waited.

Waited for a bzinga, or a twitch, or a knock on the door at three in the morning...

After two days of nothing out of the ordinary, not even a flicker of Sheldon's composure, she'd mentally shrugged and assumed he was either not going to pay her back, (which she hadn't expected anyways) or that he was still doing research and would take his sweet time about it.

Either way, she had other things to worry about, like bills, and that audition.

Sheldon had in fact been doing research.

First he'd analyzed his responses, and lack of responses. Then he'd decided on a future course of action, along with a detailed plan of what the desired outcome of this new diversion would be, and a suitable framework of steps to be taken, hypothesis to be come up with, contingency plans should a step fail, or a response not be the one desired. Once his plan was complete, and, he deemed, fool-proof, he merely settled in to wait for the perfect opportunity.

It came, on a Thursday night.

He was waiting at his door when she trudged up the stairs, her work uniform crumpled and stained with something resembling ketchup.

"Hey Sheldon." She sighed, walking past him to her door and fishing out her keys. "Is it anything-can-happen-thursday today?"

"Yes." He replied simply, following her into her apartment. "I took the liberty of ordering us take-out, if that's alright?"

She nodded and motioned for him to shut the door. She'd really been hoping for the night alone, with a good book and maybe an escapade with the shower head, but now that he mentioned food she knew she was hungry, and it HAD become sort of tradition for him to spend those Thursdays with her, because she had no desire to go to bars to pick up women, and when he had mentioned it previously, informed him that showing up with THREE desperate looking guys was a surefire way to not pick up men either.

So anything-can-happen-thursday had become Sheldon and Penny time, as long as Amy or a grad student eager for a title-sharing credit didn't interfere, and Penny liked it. Of course, the continued one on one exposure had lead to the thoughts, and the dreams, and the actions, of what had taken place in the laundry room, though she had to admit she would never had acted so quickly had it not been such a perfect set-up.

Him, already strung out, way out of his comfort zone, and her with the sure-fire remedy...

She smiled at him and hooked a thumb over her shoulder. "You pick the movie I'm going to go shower."

He was already perusing her video collection and barely even nodded.

Just another Thursday night with the robot man.

Dinner was good, the movie was better, she hadn't watched it with Sheldon before because, well, it had a fair amount of R rated action, but he'd picked it out. He'd watched most of it with one eyebrow raised, the sex in public scene had rated two raised eyebrows and a faintly disbelieving sniff.

She had to agree.

Someone in that crowd would have for sure started a fuss instead of just wandering around smiling.

Sheldon watched her as the credits rolled, his mind working. He had chosen this film because she had always passed it over, and the way her colour had deepened in a few places, the aberrations of her breathing pattern had reassured him that his calender had not lied. If he did not act tonight, she would be going out tomorrow night. He pondered for a second waiting for the next night, but reasoned that as she had no room mate she would self-satisfy tonight and thus take the edge off for the next night, and that just wouldn't do.

She stood up abruptly and left the room, heading for the bathroom.

He gave her a minute, and then followed.

When she came out of the bathroom, her face pink from having been scrubbed with cold water, he was leaning against the wall facing her.

She blinked in surprise.

"Penny." He narrowed his eyes. "Come here."

She stepped towards him instinctively, and found herself suddenly with her back to the wall and him in front of her, leaning towards her like she was his whiteboard.

"You seem a little flushed." He whispered, his blue eyes staring into hers knowingly.

"Damn you." She hissed slightly, as she felt one of his fingers trailing on the top of her sweatpants.

His lips quirked, and the finger dipped slightly under the waistband. "Is that a no?"

Her hand seized his shirt in a vice like grip. "Don't you even DARE stop."

So he didn't.

His head came to rest on the wall beside hers, his leg pressed between hers, both spreading her legs slightly and serving as a support. He was determined to do this as she had, with one hand alone, focused on the task. It had left him wanting more, he wanted her to want more as well.

His hand slipped lower, and began to move, and explore, tracing her with the tips of his fingers then delving inside, his thumb finding the spot which all the diagrams had agreed on, the spot labelled as a 'sure-fire' way to make a girl scream.

She didn't scream, but she did make a sort of breathy sound that he found fascinating, so made her do it again.

And again.

When he finally stopped, her eyes were glazed over, and he almost entirely supporting her weight.

Her hand was still clutching his shirt.

Her breathing was heavy.

"Did you google that?" She whispered.

He nodded.

"Wow."

He cleared his throat. "When you make that noise, and inside.." He ventured.

"Yes Sheldon, you know longer owe me one." She half smiled, looking down and noticing that she still had her sweats on and that he had so far not made a move to reach for the disinfectant she was sure he had on him somewhere, though she could see his fingers glistening in the dim light.

When her eyes returned to his, she saw the cat like grin on his face and a tiny line appeared between her eyebrows. "What?"

He stepped away from her and let her slide down the wall a bit till she forced her legs to hold her up. "In that case." He definitely smirked, "I believe you now owe me again. "As you made that noise THREE times."

She managed a half glare as he sauntered out of her room, and then her apartment, before she collapsed on her bed with a smirk of her own, because how could you be mad about getting exactly what you wanted?
