Amy didn't know what she got herself into when Sheldon said he was going to show her what he was capable of. She felt bad for scratching him so bad when they were in bed, but in a way she felt like she was leaving her mark. Little did she know that Sheldon was planning on doing the exact same thing.

He grabbed her hand and pulled her to his bedroom and he wasted no time getting her clothes off. Before long they were rolling in bed kissing when Sheldon began to pay special attention to her neck. Amy loved when he did this; she felt like all of her nerves were set ablaze and she had no desire to put them out. This time though, Sheldon had no mercy. He sucked hard on her skin and licked every inch that he ran his lips over from her neck all the way down to her collar bone. Amy was enjoying all of the sensations she felt but then realized what he was doing.

"Are you trying to give me a hickey?" She asked raising her head up to look at him. He grinned at her and whispered in a low voice

"Sweetheart, you're going to wish it was just a hickey by the time I'm done with you"

Holy crap she thought to herself as his lips kept moving lower. He reached her breasts and kissed the tops of them before sucking and licking just as he did to the rest of her chest. He then took her nipple into his mouth and Amy threw her head back and gasped before grabbing Sheldon's hair. He grinned at this and continued assaulting the remainder of both her breasts with his mouth until it was evident that his mouth had obviously been there.

In order to heighten her pleasure he ran his fingers down to her heat and slipped one inside of her soliciting another gasp from her. She breathed hard and kept one of her hands in Sheldon's hair and the other gripping the sheets underneath her. He slowly moved his finger in and out of her before kissing down her stomach and stopping at her hips. He gave her a strange look; a look of warning almost. Then he sunk his teeth into her right hip and she screamed. She screamed because she had expected it to hurt her, but all she felt was pleasure mixed with the feelings she was getting from his hand down below. Sheldon kissed over the marks his teeth had left in her hip and then moved to the other to kiss and suck the flesh covering her bones. She'll never know how much I love her skin he thought to himself. After a few minutes he made Amy turn to lay on her stomach and he moved her hair so he could kiss the back of her neck. Soon his lips moved down and he sunk his teeth into her shoulder and she screamed

"Oh, Sheldon!"

Sheldon grinned at this. He loved that he was marking his woman all over her body and she couldn't help but enjoy it. A part of him couldn't even believe that he was enjoying it, but he wasn't about to stop. He kissed and sucked the rest of the skin that covered her back until she was covered in obvious bruises of love. When he was finished he wrapped his arms around Amy and pulled her so she was lying on her side. He stayed behind her and positioned himself at her entrance and she was surprised; they had never tried it this way before. As soon as he entered her she moaned and layed her head in the crook of his neck. He draped his arm over her and held her close as he moved deep inside her and giving himself more pleasure than he could have ever imagined. He leaned down to kiss her forehead and Amy's eyes fluttered opened and she whispered

"You have no idea how good you make me feel"

He smiled and kissed her forehead again, squeezing her to his chest and he whispered

"You have no idea how alive you make me feel"

He continued to move deep inside of her and quicked his pace and Amy's breathing quickened as well.

"That's good, Sheldon. Just like that"

He moved faster and moved his hand up to cup one of her breasts, loving the feeling of her soft skin in his hands. She moaned and he could tell she was getting close; she would always lick her lips right as she was about to cum. Just as she brought her tongue out to lip those beautiful lips Sheldon leaned down and kissed her and he felt her body convulse. She came hard and Sheldon kept his lips on hers the whole time and she moaned loud into his mouth and he enjoyed every second of it. He closed his eyes and finally released her lips and she mumbled

"God Sheldon, you're amazing"

His ego certainly appreciated that. Sure, he knew that he excelled at everything but it was always nice to hear it. He felt himself getting close and he gripped onto Amy hard as he pounded into her. She closed her eyes and held herself against his body as he screamed and released his warmth inside of her; a feeling she never grew tired of. He collapsed against her and she turned to lay on her stomach and he laid on her back. He smiled as he inhaled the scent of her hair. I love that that scent more than anything he thought to himself as he snuggled against Amy's body. She smiled and enjoyed the feeling of Sheldon being so close to her. When they were in public he barely touched her, so moments like this she learned to cherish without question.

The next morning Amy got up to take a shower and she looked at herself in the mirror and her jaw dropped. If she didn't know any better, she would have assumed someone beat and assaulted her the night before. Sheldon had definitely left his mark. Her neck, breasts and part of her stomach were covered in bruises made by Sheldon's lips and tongue. Her hips had bite marks as did her shoulders and her lower back. She looked like she would be in a ton of pain but she felt none. She felt an overwhelming feeling of love take over her as she realized that Sheldon did this. Sheldon gave her these beautiful bruises as a sign of his love and affection for her. She wore several layers so she wouldn't have any issues hiding them, well, except for the ones on her neck.

Sheldon walked into the bathroom as Amy was rubbing foundation furiously on her neck to try and hide the hickeys that covered it.

"Rats, I should have been more careful" he said as he watched her pour more foundation in her hands. She shook her head and said

"Nonsense, Sheldon. I love what you did; I just know that I can't go out in public like this. Plus if our friends saw there would be absolutely no other way to explain this unless you tell them somebody tried to strangle me"

Sheldon thought about it but soon dismissed it and he placed a hand on Amy's shoulder.

"Well, I'm sorry for leaving you with so many marks to deal with, but I told you I'd get even with you for what you did to my back" Amy smiled and turned to face him.

"I'm not sorry at all, Dr. Cooper. I will wear these marks proudly knowing that they came from those beautiful lips of yours" She gave him a quick kiss and continued getting ready for her day.

Later on that evening, Sheldon and Leonard were playing Halo so Penny came over to spend some time with Amy. They were chatting about different things that had been going on.

"How's living with Dr. Whackodoodle? Driving you crazy yet?" Amy smiled and shook her head and reached for a bottle of wine and two glasses.

"It's actually going really well, Penny. We don't argue, were almost completely used to each other's schedules and everything has just been… well, nice" Penny smiled and raised her eyebrows in surprise.

"Well that's great, sweetie! I'm glad you guys are getting along" She glanced back at the boys to make sure they weren't paying attention before leaning forward closer to Amy and whispering

"How are you handling living with him and not having sex?"

Amy froze as she was trying to get the cork out of the wine bottle. She knew she couldn't say anything. She knew that this was her and Sheldon's secret and by not telling anyone it had turned into the best dirty little secret she ever had. She swallowed before continuing to open the wine bottle.

"It's alright. Sure I have moments where I just want to rip his clothes off and have my way with him, but I'm getting used to it" Penny nodded and frowned and she handed Amy her glass.

"Oh sweetie, I just hope he doesn't make you wait forever. You deserve so much better than that"

If you only knew she thought to herself as she began pouring wine into the glass. Then her hand accidently slipped and she poured wine all over her cardigan and shirt.

"Damn it! Oh well, I'll be right back Penny I'm just gonna change shirts real quick" Amy made her way to the bedroom and the boys began to argue about their game so Penny decided to follow Amy in there to escape the madness. She walked into Amy's bedroom and dropped her wine glass to the floor when she saw Amy without a shirt on. Amy jumped at the noise and turned to look at Penny before covering herself. Penny raised an eyebrow and said

"Alright, Amy. You'd better have a damn good explanation for this"
