A/N : Thank you Hazelra7 for beta-reading!

It was Friday afternoon – or prevening as Sheldon called it – and the seminar was over. It didn't make much sense to head to work now for just about an hour before calling it a week, so Amy and Sheldon decided to go to 4A to spend some time together before Leonard would be home.

They were preparing tea. Amy was helping him getting all the ingredients from the different cupboards and shelves. While he was enjoying watching her, it struck Sheldon how much at ease she knew her way around in his kitchen, and more so, how much he liked it.

"Have you thought about it already?" He asked her bluntly.

"Have I thought about what?" She repeated confused.

"What I asked you this morning," Sheldon replied.

"Well, that was one rollercoaster of a day, and you asked me a great deal of questions during the seminar, which one are you referring to now?" Amy asked, still wondering what he was up to now.

"To the one you said you needed to think about," he tried to clarify further.

"Sheldon, not everyone around you has an eidetic memory, and… oh." She stopped, as the realization suddenly hit her. He had brought up the topic of living together on his own volition! Okay, to be honest, he hadn't asked her directly to move in with him earlier, he had just said that she could apply as well when he would be looking for a new roommate at some point in the future. For Sheldon, that was huge. But she didn't want to get her hopes up, so she'd dismissed it and said she'd think about it.

"Sheldon, I've been burnt too many times with that topic – if it even is what I think it is. I'm not gonna jump to hasty conclusions here. Tell me what exactly you wanted to know." Amy didn't want to tease him, she really needed the confirmation.

Sheldon looked at her longingly. "Have you considered… moving in with me? I mean, not right now… there has to be some order and structure and testing time… we'd need a whole new agreement, that's a lot of work… and I'm truly sorry about how I've been treating that topic in the past," he finished meekly.

Suddenly Amy flung herself into his arms, kissing him eagerly. He didn't see that coming, but didn't hesitate to reciprocate. When they came up for air, Amy grinning at him, he smiled at her and asked, "I'm really not the best with body language… does that mean you would agree?"

"I would, indeed," she beamed at him. "We could do it gradually just like you do with Leonard moving out… start with two days a week… that's what we're doing anyway with the sleepovers."

"Oh," Sheldon replied. That's not exactly what he had in mind. "Uhm… Since it's Friday now, and the sleepovers are on Thursday and Saturday, I've been thinking about three days in a row… it would just make sense, there'd be less running to and fro between our apartments… it simply preserves time and energy…"

"You're really serious?" She asked, and he nodded. "Sheldon, I'd love that! …But we need to tell Penny and Leonard."

"You're right. I should have given him a note 24 hours in advance… but neither did he all these times. I'm sure they've guessed already what we've been… up to the last weeks," he answered sheepishly. "Let the jokes begin," he sighed in a self-deprecating manner.

"I don't think they would make fun of us… I hope. They're our friends," Amy tried to calm him.

"Exactly," he muttered.

Leonard and Penny entered the apartment a while later. Amy and Sheldon had just finished their tea.

"Oh good, you're here! We've got some exciting news to tell you," Sheldon said, smiling at Amy and taking her hand while they moved from the kitchen counter to meet them.

"Okay, let me guess," Penny answered. "You will try to get another turtle?"

"We will, but that's another topic," Amy answered, smiling back at Sheldon.

"It's even better: We will be living together, as a trial period only on date nights and weekends, for starters," Sheldon explained.

"I thought you were doing that already," Leonard answered unimpressed.

"No, Sweetie, they're talking about three days in a row now, that's already half the time!" At least Penny was more excited.

"Penny. Three divided by seven is merely 42.9 percent of the time," Sheldon explained. "And Leonard, you might want to buy your own noise-cancelling headphones," he continued, causing Amy to blush.

"Oh sure, like I would ever need them… no offense, Amy," Leonard replied sarcastically and went to the fridge to get something to drink. Penny followed him to the counter.

"Just because we've been… very discreet… doesn't mean it will stay like that forever. We just wanted to give you a heads-up," Amy explained patiently, kind of expecting Penny to freak out. She had been dying to tell her on girl's night about their progress, but had restrained herself, not wanting to have Sheldon humiliated by the guy's jokes.

Penny, however, was not impressed. She just grabbed two glasses from the cupboard and put them on the counter.

"I know what this is," Leonard said, filling in some water for Penny and him. "You're doing your little experiments on us again!"

"I assure you that we've been intimate for a while now," Sheldon said, placing his arm around Amy's shoulder and pulling her closer to him.

"Hey, you're getting better at this, buddy," Leonard grinned and took a sip from his glass. "I didn't see any twitching in your face at all!"

"That's because it's the truth," Sheldon said exasperated.

"Yeah, right, just like your herb garden rumors," Penny exclaimed. "Aloof, but effective, right? Why don't you give us some coins to sort while you're at it?"

"I can assure you there's nothing aloof about it… more like whimsically inventive, I dare say," Amy leered at Sheldon, making him blush now.

"Sure, fine, whatever. Hey, we're just heading out to get our Chinese food. You'll want your usual orders, I assume?" Leonard asked.

Sheldon just nodded wearily, and Amy answered, "Tangerine chicken for me as well, please."

"Got it, see you later," Penny said, putting the empty glasses in the sink; and they left.

"I don't believe they don't believe us," Amy said, shaking her head at this turn of events on their great announcement.

"I know… and even worse, we might probably starve to death since Penny took our order," Sheldon complained.

"Hey, good one, you were funny on purpose," Amy laughed.

"Actually, I wasn't," Sheldon replied. "Hmm… We don't seem to be really convincing, despite after all we've learned today… We might have lied to them too often. What else could we do?" he wondered.

"I don't know," Amy shook her head again. "We could be doing it right here in your spot and they would still think we just faked it," she grinned.

"Hmm…" Sheldon pondered, eyeing her up and down, resting his chin on his thumb and forefinger.

"Oh no, that was just me trying to make a joke… you're not thinking that…" Amy started.

"Hmm…" He resumed and licked his lips, looking into her eyes very calmly.

"You… you can't truly be thinking that!" Amy was terrified of getting caught… on purpose, even! But at the same time she was strangely thrilled by this idea – and by the seductive humming sounds he was making… and the way he was staring at her intensely now.

"C'mere…" He hugged her close to him in front of the couch, nuzzling his nose in her hair to inhale her scent.

"Sheldon, I'm not getting naked here!" Amy exclaimed, but started to hug him back. He just smelled too good, there was nothing she could do.

"Too bad… but not necessarily needed…" His husky voice was sending tremors down to her belly.

He sat down in his spot, taking her with him so that she was straddling him, her skirt riding up on her thighs. With Amy in his lap, they had the perfect angle for kissing, no need to bend down, he mused. Then his mouth was on hers, his tongue prying open her lips to be granted entry. She welcomed him with her own, sliding up against him as their breaths mingled with the sweet smell of peppermint tea and honey they had just shared. As if they had a mind of their own, her hips were grinding down on him, delighted by the torturous friction from the growing bulge in his pants between them.

In the meantime, Sheldon had unbuttoned her cardigan, and she shrugged it off, tossing it over to the armchair. They were kissing passionately again and Amy began to stroke him through his pants.

He bucked his hips against her, but he was getting too excited already and needed to calm down. "Whoa, whoa, no hurry… let's take it slow… we've got all the time in the world," he groaned.

"Are you sure… you wanna stay here? You're really serious about that?" Amy asked breathily.

"I am. And I can be very… patient… to prove a point," he whispered into her ear and softly bit her earlobe.

"Dear Lord, I'm in serious trouble now…" Amy began to moan softly as she felt his hot breath on her neck and his mouth on her skin; he knew exactly which spots were driving her crazy.

"You're just now realizing that?" He began to unbutton her blouse.

Amy was writhing against him in his lap. "Sheldon… I want you so badly… but I'm not getting naked here…"

"Shh… I know that… we'll keep it on… but I need to feel your skin…"

"Then let's start with you, Dr. Cooper," she said, pulling both his shirts up over his head.

They melted together in a tight embrace, reveling in the sensation of her bare belly pressed against his own. They kissed again, delicately stroking each other's skin, while Amy grounded her hips against him more and more urgently.

"I don't care if they'll catch us… I need you inside me… now!" Amy panted. Her heart was beating so fast now, and her eyes were already half-lidded with desire.

"That's the spirit," Sheldon said hoarsely.

Amy got up to remove her panties in a frenzy and kicked off her shoes. Sheldon unzipped his pants but kept them on so that just his erection sprung free. Amy hurried to climb back onto his lap, hiking up her skirt to take him all in. They both moaned when they were finally joined, both their eyes closing in pleasure at the contact.

Sheldon held her hips while they began to move in long, slow strokes. Their lips met again, their tongues playing lazily with each other. Amy's hands were stroking through his hair while they kissed. She loved the feeling of his short-cropped strands of hair gliding through her fingers. Sheldon's hands were caressing her posterior and holding her in place. They wanted to make it last and enjoy the special bond they shared.

And that's how Leonard and Penny found them. They came back some time later, finding Amy straddling a half-naked Sheldon in his spot, his hair messed up like sex on a stick, her cardigan carelessly thrown over the armchair next to his shirts and her orthopedic shoes tossed to the floor. Her arms were around his neck now, her blouse unbuttoned and wrinkled, pulled out of her skirt. Her skirt, albeit still on, had ridden up her thighs and was now only scarcely covering her bare legs. They were kissing each other leisurely while she was slowly gyrating her hips on him with his hands gripping her bottom. Amy didn't even care anymore about the interruption at this point.

"I can't believe I forgot my wallet here," Leonard said. Then he spotted them on the couch. "Hey guys… the joke's getting old, give it a rest," he said, taking Penny's hand who just shook her head as they left again.

Sheldon smirked as he heard Penny asking, "Has he been secretly working out?" And Leonard replied, "Phew, this is Sheldon we're talking about!"

"Told you so." Amy's sonorous voice was vibrating near his ear.

"I knew… we should have… removed our clothes," Sheldon panted. As he started to push back into her more forcefully she could only moan in response.

They had been going like this for quite some time now, their feelings intensifying slowly, but steadily. However, all this built-up was going to channel into some form of release soon, and they were both reaching a point of no return. Their kiss became more urgent and passionate and their lovemaking faster and more erratic.

When Sheldon sensed he couldn't take much more, he reached down between them, pressing on the swollen nub between her legs in tiny circles, and bent his head towards her neck, sucking on her cervical artery. And so they were flying off together over the edge, their cries of pleasure muffled by their kiss as they slowly came back down to earth holding each other tightly, spent and satisfied.

A/N: Queenfisher posted in the forums the following idea: "I'd like to see a Shamy plot where the Shamy announces the news of them having sex to people but everyone won't believe them and the Shamy just shrug their shoulders and continue having sex unintentionally in secret." I used this great idea for this chapter, I hope it's ok with you!
