Amy couldn't believe it really happened. She was sitting in a hot cosy bathtub half-naked with her – also half-naked – boyfriend, and he was kissing her neck while his hands were still caressing her lower back. She tried her hardest not to moan but sometimes little noises found their way out of her mouth and she wasn't sure but it felt like it encouraged Sheldon. His right hand slowly wandered onto her hip, stoping right over the waistband of her panties. His nose nuzzled against the hairline in her neck, planting another soft kiss on it.

Amy tried to calm herself down, she felt her heart racing. But just when she had thought she would eventually get it under control, Sheldon's left hand laid on her shoulder and slightly pushed her back, signalizing she could lean against his upper body.

Goosebumps rushed over Amy's entire body as she felt his wet chest hair against her naked back. His right hand automatically slipped on her belly. As soon as she had relaxed and was leaning fully against him, he put his left hand under her chin, turning her head to the left, just so he could plant yet another soft kiss on her cheek. He smiled when he saw her blush. She quickly turned her head back and tried yet again to calm herself down. But Sheldon didn't seem to want to give her a chance for that. He put his lips back on the side of her neck, kissed it and finally slightly and playfully bit it.

Amy had had no idea that Sheldon knew exactly what would drive a woman crazy. Or at least her.

If only she had known that the physicist had already crossed a line he never thought he would. He was caught up in a whirlpool of lust and the need to satisfy his woman.

"Tell me that you want this" He whispered and his hot breath hit her shoulder.

Amy swallowed. "I do. I want this."

"How much?" His voice was so deep and throaty, that Amy closed her eyes to not lose her mind immediately.

"More than anything else"

That was enough. He had her where he had wanted her. He loved being in control. He loved knowing that he had control over her pleasure. Slightly biting her shoulder this time, he quickly slid his right hand into her panties.

Amy wasn't in control of herself anymore, she let go a loud moan and arched her back. But Sheldon didn't want her to break the contact between her back and his chest, so he quickly wrapped his left arm around her torso and pulled her back. Amy only knew that if he kept being so great at what he was doing, she wouldn't last longer than a few more minutes. And she wasn't quite sure yet if that would make him feel like a winner or if it would frustrate him.

It only took a few seconds for Sheldon's index and middle finger to find the little hot spot that would catapult his girlfriend into other dimensions.

Without really realizing, Amy's fingernails dug into Sheldon's thighs. A cheeky but very satisfied smile darted across his lips. It was a deadly mix of going up and down and then around in a few circles, that let Amy bend her pelvis back, overwhelmed by the feeling.

He would never have admitted it, but Sheldon had definitely read the book his friends had given him a few years ago. And not only that. He had browsed Google and Wikipedia and had watched a video or two – only for learning purpose of course. The only woman who had any sexual affect on him was Amy anyway.

Sheldon started to really enjoy how Amy was under his control and how he was the master of her body. He could torture her and make this take hours… or he could just send her right over the edge. He was well aware of his power.

Deciding he would tease her just a little more, he nibbled at her earlobe. He was tempted to finally touch her breasts with his left hand, feeling the full round so perfect amount of it but he knew that if he did that in that very moment, Amy wouldn't have been able to last anymore. He had never done anything like that to a woman before but somehow he could tell. He felt some contractions here and there and he wasn't a complete idiot – he knew what it meant.

He was drawn away from his thoughts when he heard another moan from Amy. His eyes darted up and he saw that she had turned her head aside. Eyes closed, she bit her moist lips just before she let go yet another sigh of absolute satisfaction.

Sheldon swallowed. Until now he had thought he was the one in control but – probably without knowing – Amy had him under his spell now, too.

He wanted her. Badly.

On the other hand, he didn't want to have her and his first time here. It would be clumsy enough on the bed anyway, no need to make it even more complicated in a slippery bathtub.

Amy moaned again and just when Sheldon decided he would send her over the edge and his senses were sharpened enough to suck in every motion of hers, every look in her eyes, every little movement she was about to make, he heard a voice.

Sheldon immediately pulled both his hands back and sat up straight in the bathtub. It took Amy a few seconds to quite come back to reality. Then she let go a frustrated sigh and angrily stared at the closed bathroom door.

"Sheldon, are you in there?" A knock on the door.

"Uhm… yes! I'm… helping Amy!"

Amy elbowed Sheldon into the ribs and he shrugged helplessly.

It was quiet on the other end of the door.

"I fell and he helped me get up!" Amy quickly added.

"Are you okay?" They heard Leonard putting his ear onto the door, he sounded worried.

"Yes, I am fine. What's the matter?"

"Well, the Warlords of Ka'a evening at Wolowitzes…"

Amy turned around and glanced at Sheldon but he just shrugged again.

"He'll be there in a few minutes, okay?"

Leonard seemed hesitant. "Uhm, alright… I'll wait in the living room."

When they finally heard him move away from the door, Amy moved away from Sheldon and turned back around. She was about to spill all her frustration out on him but then she saw that he seemed just as frustrated as her.

Amy sighed, swallowed down all the lust that was still within her and tried a smile. "Well, we should get out."

Sheldon just nodded and stood up. He then stepped out of the bathtub, grabbed a towel and threw it over his shoulder, before he held out both hands. Amy grabbed them and he pulled her up. He couldn't help but stare at her chest again. Swallowing down his again upcoming lust, he looked down and handed Amy the towel.

She bit her lips and wrapped herself into the warm fabric. Then – with Sheldon helping again – she climbed out of the bathtub.

Without any further word they both got dressed, always discretely staring at the other one when they weren't looking. It were ten awkward minutes of silence, then they finally were dressed and Sheldon headed towards the door.

Amy just stood there motionless, she didn't want to follow him, she just wanted to stand there and deal with her feelings and thoughts. But when Sheldon realized, that she wasn't coming along, he turned around and looked at her. It took a few seconds until she looked back and their gazes met.

The physicist sighed and then walked back to her until he stood only a few inches away from her.

"I am sorry" He whispered so quietly that even if fifty other people would have stood in the room with them, only Amy could have heard it. "I'll make it up"

He took Amy's face in his hands, smiled at her quickly and then pressed his lips onto hers. One or two delicious minutes passed, before Sheldon finally stepped back and went out of the bathroom.

"Zombie dinner" Howard dropped a card on the pile that was already lying on the couch table. Raj sighed and checked out his cards. Then he dropped another one on the table. Leonard was next and then it was Sheldon's turn.

But for the whole evening Sheldon had been thoughtful and not very talkative. At first they had thought he had been in the zone but usually he still heard something then or talked about what he was thinking. But he was awfully quiet and completely lost in his thoughts.

"Sheldon, your turn" Leonard sighed.

"Uh… stinky possum" Sheldon put the card on the table and his three friends stared at it in disbelief.

"Sheldon, you just lost" Howard's jaw dropped again. They all stared at the physicist and expected him to get angry or tell them how they all played wrong or tell them how it wasn't fair but neither of it happened.

Sheldon just bit his lower lip and then looked at Leonard. "Can we go home? I don't feel too well…"

"What's wrong? What happened?" Leonard looked at his best friend and hoped that Wolowitz wouldn't make any stupid jokes.

Sheldon really looked unwell. "I can't talk about it. I just want to go home."

"You're upset, do you want some hot chocolate?"

"This is not for when I'm upset!" Sheldon barked at Raj.

His friend shrugged and held up his hands as in saying sorry for the mistake. They all looked at Sheldon again. He seemed strange, something weird must have happened and the thought came to their minds in the same time. They looked at each other. Then Raj and Howard stared at Leonard and he silently shook his head with wide open eyes. Howard pulled down his eyebrows and nodded.

Leonard sunk his head. "Sheldon. Is everything okay with Amy?"

Since they all had expected it had been a fight with his girlfriend, they were waiting for Sheldon to freak out and either aggressively deny it or tell them how wrong Amy had been about whatever argument they had had.

But instead Sheldon's face became bright red and he swallowed and stared down at his hands. Then he shook his head a little. "No, nothing. I just think I ate something wrong and I really want to go home."

"Come on, we know it's about her" Raj had lost his patience.

Sheldon looked up, opened his mouth, closed it again and then cleared his throat. "Okay, it was because… I mean, it is because…"

"Oh, I know!" Leonard suddenly blurted out and Sheldon's facial color turned from red to white. How could he have known? Had he heard Amy's moaning? Oh, curse her and her damn hot voice.

"What is it?" Howard asked, staring around between Sheldon and Leonard.

The experimental physicist grinned. "Sheldon is worried about Amy"

Sheldon, who had held his breath, let go of all the air and then looked at Leonard in confusion before he realized what Leonard was thinking. Then he nodded furiously.

"Amy slipped in the bathroom today and now I just think he's very worried about her"

"Well" Howard still was looking around between them. "That is cute but why does that make you feel unwell?"

"I am worried about her. I mean God knows what this clumsy woman does next, right? That is why I want to go home. So, Leonard?"

"Don't you think you can just call her and check up on her like this?" Raj asked.

Sheldon sent him a death glare. "No. She'll lie about it. She doesn't want me to worry. You really know nothing about women!"

"Ouch" Howard whispered while eyeing Raj worridly from aside. Everyone had always been careful talking about Raj and his problems to find a woman, most of all because they knew that it wasn't that hard to make him cry. But apparently Raj had hit a raw nerve in Sheldon's crazy universe.

"If you don't drive me, I'll go by bus!" Sheldon stood up and went over to grab his jacket.

"You don't have your bus pants with you"

"But I have signed a contract three years ago, which states that I am there for my woman when she's in need. Screw the bus pants!" Grabbing his satchel, he walked out of the apartment and slammed the door shut.

"Did he just say 'screw the bus pants'?" Howard stared at the door with wide open eyes.

His both friends just nodded with the same shocked facial expression.
