A/N: I can't believe how well this has been received so far, thank you all so much! It's really motivated me to continue with this. Big Shamy love to you all!

N.B. I will have to change the rating of this to an M due to what's going to be involved at times throughout this story. It won't all be smut, but I'm intending to write a little bit. I'll note at the start of each chapter whether there will be sexual content or not so you can make your own decision as to whether you'd like to read it or wait for the next chapter. Regardless, it'll still be full of Shamy's beautiful love, sexual or non-sexual. Enjoy!

Chapter 2: 'The Arousal Potential'

Sheldon woke up next to Amy in a daze, not used to unscheduled naps. He frowned for a moment, trying to recollect how he got here and into this situation. It all suddenly came flooding back to him, and he smiled softly as he watched his Amy sleeping peacefully. With his free hand, he gently stroked her face with the back of his fingers. She stirred, as he gradually moved his fingers through her hair, and she half-opened her eyes to see him looking back at her with a relaxed crooked smile. She smiled back, to which he responded by placing a gentle kiss on her forehead. She closed her eyes and deeply sighed, still slightly convinced that she was dreaming, though she hoped she wasn't! They continued to gaze at each other, lying very close together as they had limited space on the couch. Sheldon slowly leaned in to lock his lips with Amy's once more, holding her close to him with his free hand still in her hair.

Amy continued to embrace these moments with Sheldon, not knowing when this might happen again. Sheldon wouldn't just do this for the sake of it, though. Did Sheldon want to alter the paradigm of their relationship? Is that why he wanted to experiment? Amy tried not to think too much or jinx anything, as she proceeded to stroke her free hand over Sheldon's hips to his slender back. At that moment, Sheldon pulled back and pursed his lips, widened his eyes and jolted to an upright position on the couch.

"I can't do this." Sheldon stated, distressed by his ever-conflicting feelings. Sheldon was a straight-minded man of science; he couldn't comprehend these new unnecessary confounded emotions. Life was much simpler before all this… And yet he still wouldn't change his new life with Amy for anything in the universe.

"Sheldon, I understand," replied Amy sympathetically. She sat up and cautiously placed her hand over Sheldon's. "This is new and uncomfortable for you. We don't have to do anything you don't want to."

"But I do want to." Sheldon retorted instantly and shot his head in her direction, taking a hold of her hand which was placed over his. "Very much." He gazed into Amy's eyes, overwhelmed by just how understanding and considerate she was, not to mention beautiful. He leaned in and placed a gentle, grateful kiss on her soft lips. He looked down in contemplation. "Strange. I rarely find it this difficult to solve problems that face me. Then I met you." He frowned and looked a little frustrated. He looked up at her, slightly more relaxed, but still perplexed. "I've been distracted since the moment I met you."

Amy smiled back at Sheldon. Her smile faded slightly, and she looked down nervously as her fingers fidgeted. "Sheldon," she started, "It seems that… What is making you nervous is when I initiate the more intimate physical contact." Amy paused and started nervously looking around, away from Sheldon. He shifted his head to grab her attention, and gestured for her to continue. He strongly disliked it when people were dilly-dallying. "What if…" Amy continued, "If you're nervous about progressing, but still have the desire to do so, then it would be feasible for you to set it at your own pace. You make the first move into different physical stages of the relationship."

Sheldon lowered his eyebrows in thought. "Interesting."

"I can advise you too, if you feel it would help. It would be like the time when I helped you to massage your own back. You weren't very fond of the idea, but with my help you came to enjoy it. It might not be the same, but seeing as you wanted to experiment, this could be my way of assisting you."

"Alright," replied Sheldon, still looking a little confused. "I wouldn't even know where to start, though. Nowadays people have different preferred erogenous zones and ways in which they like those areas to be stimulated." Amy blushed while he spoke. "Honestly, why can't all humans be sexually gratified in the same way? They're all just a bunch of hippies."

"That's why you can experiment with it, though." Amy felt a little embarrassed talking about this. She know she shouldn't in order to help Sheldon, but she hadn't planned on talking about this with him so soon. "Of course I have a… general idea of how I like to be satisfied, but what's great about physical relationships is that you can test different ideas."

Sheldon seemed to approve of what Amy was suggesting. He was comforted by the fact that it could go at completely his own pace. "Okay. Should we agree that when I 'make a move', you make a similar kind of move with me, unless I state otherwise?"

"Agreed." Amy responded with a firm nod, as if they had settled some kind of business deal. Seeing as they had a formal relationship agreement, this wasn't any different to when Sheldon made changes to the document.

They awkwardly shuffled closer together and cautiously put their arms around each other. This relaxed Sheldon, and he smiled as he slowly leaned down to place his lips against Amy's. They stayed in just that position for the first few minutes, which Amy didn't mind. Sheldon was very tender when he kissed her, which she could embrace forever. Sheldon's arms were around Amy's lower waist, and he started to gentle stroke his hands around that area, whilst his kisses became slightly firmer and he let out a very quiet moan. Amy took this opportunity to stroke her hands across the back of Sheldon's neck. Her nails softly traced along the top of his spine, and this made Sheldon drop his jaw and jolt forward slightly.

"Oh, Amy," Sheldon sighed, before gently slipping his tongue into her mouth and onto hers. She gasped before quickly returning the favour, circling his tongue with her own. Sheldon discreetly slid his fingers under the top rim of her skirt and his thumbs under her upper layers of wool and polyester.

Surely this can't be happening, Amy thought. She really had to hold back from pulling his shirt off and climbing on top of him, but if she could refrain herself up until this point, she could hold off for longer. Give me strength. Technically this invited her to make a similar move, so she seized the opportunity and slid her hands down Sheldon's back, then back up and under both of his shirts. He seemed to like it when she lightly ran her nails across his skin, so she glided the back of her fingers gently up his spinal column. Sheldon stopped kissing Amy and panted in pleasure, his head raised and his eyes clenched. His breathing got heavier as her hands explored his body. Her hands slowly slid out from under his shirt and onto his lap, where she felt something not quite right near the central pelvic region. Well, not quite normal for Sheldon… But very right indeed.

He was huge. She was pretty certain he would be, and she didn't have to place her hands directly on his member to feel that his bulge was of remarkable size. They were both staring at each other, panting. They knew they both wanted it, but were reluctant to resort to that so quickly. She kept her eyes locked on Sheldon's, whilst she lightly stroked her fingers across his crotch and zipper. Sheldon seemed very anxious; anxious about what was happening, yet eager to experience more. He bit his lip to avoid gasping loudly, as he felt Amy's fingers stroke gently up the length of his member right to the tip.

Maybe he would feel less nervous if I just focused on satisfying him for now. Amy used her other hand to stroke his face, and whispered softly to him. "Close your eyes."

Sheldon obeyed. He trusted Amy; he could see it in her eyes. Despite originally agreeing that he would make the first move, he knew he wanted her to do this. Amy slowly unzipped his fly and fondled with his tight underwear to try and uncover his shaft. "Just relax," Amy whispered whilst lowering herself onto her knees on the floor, trying to ease Sheldon's anxiety, "And for just a moment, pretend I'm not here. Just focus on the physical sensation."

Sheldon felt at ease. He trusted that Amy would go at his pace, and knew that he could stop at any time should it become too much. He leant back, closed his eyes, took a deep breath and exhaled slowly. He nodded.

Amy made a gap through his unbuttoned and unzipped fly, through which Sheldon's cock darted out. He was definitely ready for this. Despite his conflicting thoughts, physiologically he wanted this. Anatomically he needed this. Amy knew she had to take it slowly, and she used all her strength not to force her mouth around the whole thing. It was huge, throbbing. There was a neat layer of pubic hair around his scrotum; she imagined that he would generally keep it neat and manageable. Slowly but gently, she stroked her fingers from the base of his scrotum up the smooth length to the tip of his cock. Sheldon trembled, and his breathing quickened. She glanced up to check that he was okay; his eyes were still closed and he was biting his lip. Her eyes resumed their position, and she gently tightened her grip on Sheldon's shaft and she started to slowly rub her hand up and down. Sheldon was panting now; Amy had been dreaming of a moment like this for so long! The movement gradually accelerated as she brought her free hand up to his firm scrotum and massaged her fingers softly in a cupping position, which spurred Sheldon on.

"Oh yes, Amy," Sheldon gasped. By this point he was moaning, and not as quietly as he'd have hoped. He repeated her name over and over and stroked his hands through her hair, which slowly seemed to be pulling her head closer to his crotch. Amy's morals took over, and she suddenly stopped and looked up at Sheldon. She prepared herself to confirm Sheldon's approval, before he interrupted her and intensely locked eyes with her.

"Amy, please. I need you."

She gasped in surprise and arousal. Amy took that as all the approval she needed. She licked Sheldon's shaft from the base to the tip, before wrapping her lips around the length and tasting everything he had to offer. This was so much better than she could have ever imagined. Amy churned his cock with both her right hand and mouth and placed her free hand underneath his shirt and across his torso, then lightly scratched her nails back down and towards his sack. With three kinds of stimulation happening, it was a little surprising that the inexperienced Sheldon could hang on for so long. Sheldon continued to gasp and started to sweat, as he stroked his hands over the top of Amy's back and shoulders before running his fingers back into her hair.

"Amy, I think I'm…"

At this point, Amy proceeded to lick around the tip of his stiff cock whilst it was still in her mouth. Sheldon tossed his head back and cried out, as he thrust his cock deeper into Amy's mouth. Amy moaned deeply and sucked him even harder. Sheldon's hands held her head in place firmly, as he shuddered and exploded inside her mouth. He continued to shudder as Amy kept her mouth around his slowly softening cock, keeping Sheldon's taste inside her mouth for a few more seconds before swallowing. She slowly slid her mouth off, licked her lips and looked up at Sheldon. She caught her breath, and then spoke.

"Fascinating."
