After they both came down from each of their highs, Sheldon slowly slipped out of her before carefully lowering her to the ground. Before she could get her t-shirt over her head, he stopped her actions with a touch of her arm, as soft eyes stared back at her.

"Stay the night?"

And who was she to say no?

Amy groaned as the buzzing of Sheldon's alarm clock ripped through the room. He had set it thirty minutes earlier so Amy could get back to her place and change for the day and Amy was feeling the affects of the loss of sleep.

They were wrapped in a warm embrace, facing each other, as her bare legs were tangled in his cotton clad ones. They might had a sex life now, but he still wore his weekly pajamas. He wasn't a monk.

Sheldon reached over and hit the snooze button, knowing it would only go off again in five minutes as he felt Amy stir.

"I don't want to go to work."

Sheldon smirked at his girlfriend's raspy morning voice before he kissed her head and sat up.

Reluctantly following, Amy looked down and smiling at the Batman shirt he had loaned her after their showers. I should take this home with me.

"It's French Toast day. Would you like some as well?"

Amy nodded with a smile as she watched him slip out of bed. He was just about to take his shirt off when he realized Amy was still in the room.

Noticing the concerned look, Amy crawled to the end of the bed. "Are you all right?"

He muffled a groan at the sight of her ass peeking outside of his shirt before nodding swiftly. "I need to change. Do you think you could..."

She'd never understand why he couldn't change in front of her if he could take her against the door, but she wasn't going to argue. "Sure," she smiled and slipped out of bed, wincing at the pain between her legs, before she walked out of the bedroom, not missing how Sheldon's eyes roamed over her backside in the process.

When Sheldon emerged from the bathroom, finished with his morning rituals, he was surprised to see the french toast already being made.

"I said I was going to make you breakfast."

"It's all right," she smiled before she flipped a piece of toast. "I figured if I did, it would save us time. Sit," she smiled, motioning to the island, "they're almost done."

Sheldon did as she told and felt his lips curl up as he inhaled the cinnamon and butter aroma before a plate of french toast was set in front of him.

Then Amy touched his shoulder tenderly and he felt himself twitch.

What is happening to me?

Amy's morning at work was like any other morning. She did her testing with Betsy and then returned her to her original lab before making her way back to her own. She realized it was time to meet the gang in the cafeteria for lunch and she was just reaching for her purse when-

"Hello, Dr. Fowler."

Amy looked up to see her boyfriend standing in the doorway as she placed her purse on the table. "Good afternoon, Dr. Cooper."

He always felt his heart skip a beat when she addressed him that way.

"I thought we'd have lunch in here. Just the two of us."

"That's very romantic," she smiled brightly.

He shrugged as he closed door and she noticed him lock it before he threw a smirk over his shoulder.

She eyed him suspiciously as he slowly made his way over to her."What are you up to?"

"I'm assuming it's like swimming," he started as he edged closer. "You should wait half an hour after you eat. But, what if we did it first?"

Amy could already feel her lady parts start to ache. Oh, why didn't I do kegel exercises this morning? "Did...what first?"

"You look good in that lab coat. Have I ever told you that?"

She watched his hands as they came up to cup the sides of her face before he lowered his head to hers, kissing her softly at first and then with growing urgency, until she was moaning against his lips.

"Sheldon," she mumbled. "We're in my lab."

He slowly pulled back to study her face. "I know where we are."

She gasped as he quickly grabbed her hips, his favorite place to touch her, and picked her up as her skirt and coat rode up her body before setting her down on the table behind her.

"Sheldon, I think- hoo!"

His hand quickly made it's way under her coat and skirt before his thumb found her center through her panties.

He continued to swipe his thumb over her core as she parted her legs further. Watching as she squirmed in her spot caused his pants to strain, comfort dwindling. Her hands went behind her on the table as her head tipped back while her lips slowly parted.

He was hypnotized at the sight before him. Knowing he was the only one that could bring her such pleasure was an incredible feeling. Soon, he was brought out of his trance when she released a deep moan. He must have hit something good. He couldn't wait much longer, for her moans were only driving him to the brink of insanity. After he quickly pulled down his pants and briefs and then rolled on a condom that he had in his pocket all morning, he pushed her skirt and lab coat up to her hips and then proceeded to pull her to the edge of the table by the hollow of her knees.

She knew she should stop him. She was in pain and that was normal for your first few times. He would understand. Not to mention, regardless of her never seeing a male's genitals in person, she knew he was on the large side. It was a surprise to herself that she could walk at all. But seeing the darkened blue his eyes had changed to, she couldn't seem to deny him. She had never had a man look at her that way and knowing it was Sheldon Cooper who was doing it was quite titillating.

Next time.

"Oh Sheldon!"

The moment he entered her, he reached to muffle her cries with his mouth, but he was too late. He couldn't help the small chuckle that escaped him as he enjoyed how vocal she could be. He grabbed onto her hips again and began his thrusts, pulling back slowly only to drive back in. "Ohh, Amy..."

She bit down so hard on her bottom lip she thought she had drawn blood. She gasped when she felt a hand leave her hip before it disappeared between her legs to roughly thumb the sensitive nub.

"Sheldon!" She quickly realized how loud she was being and sucked her lips in, trying to keep her screams to a minimum.

It was easier said than done.

"Almost," he groaned as he continued to drive into her, pulling her hips to him every time. "Just... a couple...more... thrusts..."

"Yes, Sheldon." She could feel beads of sweat travel down the valley of her breasts and gasped when she felt Sheldon's lips on her throat. She picked up a hand from the table before she lowered it to graze his shaft every time he moved out.

"Dear lord," he moaned through gritted teeth before he couldn't hold on any longer and he dug his nails into her hips as he came hard inside her.

He knew Amy hadn't reached her orgasm yet and since he had no more to give her in terms of energy, he decided to try something he had been meaning to for the past couple days.

When he pulled out of her completely, she groaned and gave him a death stare as he took off the condom to dispose in the trash. "You can't just have your fun and then leave me he- What are you do-? Oh... my..." She felt her back hit the table as all motor skills fell out the window the moment he found her clit with his mouth. "Yes! Oh God, yes!"

He suckled and nibbled on it roughly as he felt her wetness against his lips as her hand ran through his hair. Teasingly, he let his tongue slide down her slit before inserting the tip into her, drawling a guttural moan from her throat and within seconds, she came into his mouth.

"Wow." It seemed to be the only word she could seem to use to express herself after he made her orgasm.

Slowly, Sheldon stood from the floor and helped her up off the table before wrapping her up in a tight hug.

"Say it," she whispered.

He rolled his eyes with a smile before squeezing her tighter. "I love you."

She grinned brightly as her cheek was pressed against his chest. "I love you, too."

"Of course you do. Why else would you make me say it?" He received a slap to the chest in return.

After they both dressed and flattened their hair, they sat down and opened up their lunches, quickly tossing smiles in each others direction.

"Sheldon," Amy started, eyes still on the road. "Are we planning on adding sex in the Relationship Agreement? Because if you haven't noticed, we kiss every time and those times were obviously not Date Nights."

They were half way back to his apartment after their work day and both were still spent from their love-making in her lab.

Sheldon fiddled with his messenger bag on his lap. "Well, do you want to?"

"Would you put sex in for only Date Nights."

Sheldon cringed at the idea. He didn't want to wait a month to have sex with Amy again. "Maybe we can alter the Relationship Agreement?"

"In what way?" She turned onto Los Robles Avenue.

"Well, we could change kissing to be done whenever both parties see fit and add coitus in the same fashion."

"So, I can kiss you whenever I want?" She had a hard time hiding her smile at the thought.

He nodded curtly. "Yes, and the same goes for coitus."

"So what's the point of having them in the agreement if we can do it whenever we want?" She watched Sheldon's eye twitch.

"Just because we can do it willy nilly doesn't mean we can't have it in writing. We're not savages, Amy."

Really? Because you were sure acting like one in my lab."

Sheldon blushed and quickly unbuckled once she stopped the car in front of his building. She almost felt bad for embarrassing him.

Almost.

"Will I see you tomorrow for Pizza Night?"

"I wouldn't miss it," she beamed as she watched him step out of the car. "Sheldon, aren't you forgetting something?"

He looked around the front seat seeming clueless.

"Don't I get a goodbye kiss?"

"Oh," he nodded before he leaned in, placing his hands on the seat before their lips met. What Amy thought was going to be a quick peck, turning into a passionate lip-lock that left both Amy and Sheldon gasping for breath when he finally pulled back.

Their faces were only a couple inches from each other when he spoke. "I'll see you tomorrow night, then."

All she could do was nod as she watched him pull himself out of the car and shut the door before making his way to the front door.

Laying in bed that night, Sheldon knew something was... different. He was still the genius he always was, but this new physical part of his and Amy's relationship was controlling him. He couldn't seem to stay away from her and even the simplest touches always sent him reeling.

"I just have to learn to control my urges."

Little did he know, it was easier said than done.

Pizza Night was like any other Pizza Night. The gang sat around, ate pizza and talked about anything that came to mind.

Though, it was obvious to Amy and Sheldon that their friends wanted to ask questions about their new found sex life, none of their friends would bring up such an uncomfortable topic.

The topic itself wasn't uncomfortable, but the people it involved sure were.

When everyone had left for the night, Amy and Sheldon were sitting on the floor playing a game of Go Fish.

"Do you have any fives?"

"Go Fish."

Sheldon reached over and took a card from the deck.

"Do you have any fours?"

Sheldon handed over the two fours he had been saving with a pouting face.

"Is somebody sad that they're losing?" she asked in a baby tone and mocked a pout before she reached over with one hand and tickled his belly.

"Hey, stop that," he laughed while he tried to hold his hand of cards out of her view.

Amy laughed and continued to tickle him, placing her hand down on the floor before using both hands to playfully torture her boyfriend.

"Someone doesn't like to play dirty." Her fingers moved up to his neck and tickled right behind his ear.

He let go of his hand of cards and tried to grab her wrists, but she only dropped them to his stomach again and relished in his laughter.

She grinned as she continued to watch him squirm until he flipped her under him and pinned her wrists above her head.

She stared up at him in complete shock, the wind knocked out of her, as he hovered above her with a smirk on his face. Oh my, he's like the Energizer bunny.

"I can play dirty, too." His eyes traveled from her face down to her neck before he saw the slit of her blouse. Stop it, Cooper. You said you were going to control yourself.

Unfortunately, the way Amy stared back at him as she licked her top lip, caused Sheldon to lose the battle. He quickly swooped his head down and pressed his lips to hers, earning a moan from his bespectacled girlfriend.

Removing her wrists from his grasp, he quickly ripped open her cardigan and blouse at the same time before she sat up so she could shrug them off her shoulders. "You're going to buy me new clothes," she smirked once his lips found her throat and she placed her hands behind her on the carpet.

"I'll buy you whatever you want," he muttered.

She closed her eyes and felt him start to work on her skirt, tugging it off along with her panties.

Amy reached up and pulled both his shirts over his head, running her hands down his biceps to his forearms and up again.

Sheldon then removed her glasses and set them on the table before he took off her t-shirt and then reached in the back to unclasp her bra until he realized there was no clasp. "How do I get this off of you."

She laughed and he twitched at the sound until he watched her move her hands to the front of her bra and realized his mistake.

Groaning at the sight of her perky breasts, he lowered his head and place soft kisses on the top of her breasts as she ran her fingers through his hair until-

"Oh Sheldon!" She quickly looked down to see he had taken her left nipple into his mouth and was sucking on it rigorously. She moved her hands back to behind her but her shaking arms was making it hard to keep her balance.

Feeling her shaking beneath him, he wrapped his arms around her back and slowly lowered her onto the floor, his lips never losing contact with her nipple.

"Sheldon, please," she pleaded and he grinned against her breast before he sat up and began to stroke his member that desperately needed release. Amy sat up on her elbows and watched him touch himself and could easily say it was something she never thought she'd see. She could die right then and there and would be able to say she lived a fulfilling life.

When he found his pants, he quickly took a condom out and rolled it on before he grabbed one of her hips and positioned himself with the other before he sunk deep inside her.

"Shit." She pulled him down by his shoulders and scraped her nails into his flesh as he increased the speed of his thrusts until he was slamming into her almost violently.

"Amy," he grunted and felt his arms shaking as they held him up off the floor on either side of her.

"Ohhh, that's it" she screamed and egged him on by squeezing his butt.

He reached a hand down and began to stroke her clit before Amy reacted by having her back arch off the floor, increasing the pressure of his pleasuring as she cried out his name.

He felt himself getting close and pressed his lips to hers, not even attempting to hold on. He groaned loudly when he came and it was only seconds later than Amy followed, her face contorting in pleasure, before Sheldon rolled off her, leaving them gasping for breath.

As the aching returned to her nether regions and exhaustion began to wash over her, she knew she had to remember to lay off the tickling.
