Summary: The boys are gone and Penny's pining, but her mind and body are at odds.
Disclaimer: Not mine. Doesn't that make such a disclaimer unnecessary at this point in time?
Spoilers: General knowledge of both seasons 1-2, as well as specific for 1.01: Pilot, 2.22: The Classified Materials Turbulence, and 2.23: The Monopolar Expedition; AU for season 3.
Notes: alsaurusrex, thelymachy, damalur and southern_heaven for their help in figuring this one out. It only took a few months for me to do so.

Well, here's the final chapter, more of an epilogue. I hope those reading have enjoyed the story and that this is a satisfactory ending. (Originally, the last chapter was the end.) Your comments have been very much appreciated. :)

The sun had set and the only light in the room was filtered pink through the nearly transparent scarf that Penny had placed over her bedroom lamp. It cast a soft blush over Sheldon's back, making the freckles here and there barely visible. Leaning close, Penny kissed first one and then another before pulling back quickly, knowing that he'd turn to face her in the next second or two demanding to know what she was doing and why. And then he would grab the 'Protocols for a Romantic Relationship" journal he kept by the bed and add notes, thus diminishing any chance of "coitus." Like clockwork, he rolled over just as she was finishing her thought, already speaking, "Penny, why--"
She cut him off before he could even get started. "-- Sheldon, show me the Butterfly Effect." Lying back, she pushed the sheet down, baring her breasts. He was quiet for a moment, his gaze moving over the reveal of her naked body before he looked away and gave himself a little shake before speaking.
"The Butterfly Effect, as you call it, is derived from Chaos Theory. Chaos Theory is a branch of mathematics which studies the behavior of certain dynamical systems that may be highly sensitive to initial conditions. That sensitivity is what is known as "the Butterfly Effect." As a result of this sensitivity, which manifests itself as an exponential growth of error, the behavior of chaotic systems appears to be random. That is, tiny differences in the starting state of the system can lead to enormous differences in the final state of the system even over fairly small timescales. This is sometimes presented as esoteric behavior, but can be exhibited by very simple systems: for example your butterfly effect." Sitting up, Sheldon paused and began expounding on the theme. Penny sighed, his words a white noise to her own thoughts and she tried to figure out how to get him doing – and not saying – what she wanted.
"The term "butterfly effect" itself is related to the work of Edward Lorenz ..." Blah, blah, he continued on while Penny continued thinking, idly running her finger up and down his arm, but he was so immersed in his topic, he didn't even notice. "... the more poetic 'butterfly.' I, myself, don't see the difference: Seagull, butterfly, they both have wings, thus either would suffice for the analogy."
Penny rolled her eyes and realized that the time for subtlety had passed; she was going for his Kryptonite. With her eyes locked on his face, she purposefully shifted, sending her breasts bouncing in a fashion sure to capture his attention. Immediately, Sheldon stopped speaking, his eyes drawn back to her nude form. He swallowed and then continued, but now his voice was huskier. "Why you're asking about this, I have no idea. I've explained the theory to you several times and despite your far less inferior intelligence when compared to my own, I do find it rather difficult to believe that you've yet to grasp this fairly simple concept."
"Sheldon," his eyes finally met her own. "I didn't ask you to explain it to me, I asked you to show me." And she smiled, a slight curve of her lips, and then added another shimmy of her body to get the point fully across. His eyes widened, his mouth began to form a quiet 'oh!' and then he smiled back. Reaching for the sheet, he flung it off of her body completely and maneuvered until he was lying nearly across her, but not quite. Bending down, he sighed ever so softly against the curve of her neck.
"One could easily grasp the concept of the Butterfly Effect were it reduced to a smaller scale," as he spoke, his breath ghosted against her skin and every word or so, the lightest flick of his tongue brushed against her throat. "For instance, if I were to place one finger here ..." He continued, while putting his words into action. On the other side of her neck, just behind her ear, he placed one long, beautifully slender finger and stroked her skin, before crooking it ever so slightly to allow the gentlest scrape of his fingernail in a back and forth motion. "Because this is a particular erogenous zone of yours," he whispered into her other ear, "that simple, unrelated action would cause your toes to curl." His feet entangled with hers, finding the proof of his words. "Your breath to hitch, your heartbeat to speed up," and one hand moved lazily up her hipbone, tenderly dancing over her stomach before cupping her left breast and counting the number of beats per second quietly to her. And then softly, deeply, "do you understand the Butterfly Effect now?"
She gasped and arched her body, then angled towards him, her arm wrapping around his shoulders. Pressing her mouth to his, her lips parted and without words, she showed him once again that, yes, she understood. She definitely understood.
