TheDarkestShinobi: Sheldon is like the MOST attentive Dom I have ever written/experienced. All I have to say about this chapter is HOO! Lots of smut, little fluff, and hopefully lots of enjoyment.

For the Caitlyn/Barry story. PM me.

For Young's Modulus, give me another few weeks for it. I don't know where it's going to go yet if it's even going anywhere and for those that don't know what that is it is a slower story with Amy as the Dom.

Reviews are love and love you all for loving this! Thank you!

Start

"I do my best not to have you compromised when I ask you to make a decision." Sheldon stands and she follows "which is why I did not bring this up last night." Amy watches him walk to the couch before he brings the bag towards her. She bites her lip as the different possibilities enter her mind. She looks to it and tries to figure out what she has seen on the sites that could fit in the small bag. He moves it and her eyes follow it until he pulls out the dark green rope.

She has bared herself to him in her desires. There is no doubt in her mind that he has been reading what she wants for hours, but he had already brought the rope here, last night; before he knew. He had these desires too. She looks to him and has to know all of a sudden, could they be compatible in this? She has to hear it from his lips.

"Is this some kind of fantasy that you have?" Amy sounds genuinely curious and Sheldon pauses, choosing his words carefully. She's hanging off the silence between them; she knows the answer but needs to hear it.

"You are my fantasy, in whichever way you choose to give yourself to me." He decides on, but she knows it is just a bit more that. She looks away from him as she touches the rope and it looks as tempting against her skin as he knew it would be. Still, images remembered are much better than images constructed.

"I am intrigued." Amy doesn't look up at him but he watches her, looking any signs of unease. He cannot forget what happened last night and he will not have a repeat of it. He swallows as the sounds of her sobs echo in his ears. His eyes close tightly as his fist tightens, but he shakes the image away as he focuses on her now.

"The added mental stimuli from being restricted may enhance the pleasure received during coitus." She pauses, not sure how much she wants to give away but her cards are already shown. Sheldon stands straighter, on edge. "Additionally, the loss of control," she blushes and doesn't complete her sentence. Sheldon watches the shade of her cheeks turn darker as she bites her lip. He tilts his head and lets his finger run along the rope. "Start small."

Little more and start small. Amy really is nervous. She likes doing what he says and the smaller tasks let her seemingly accept the bigger ones easier. He can work with that. Suddenly, she's become a puzzle for him.

"Get undressed." He turns away from her and walks over to the couch.

Amy wants control, more specifically, she wants domination. He read her sites, and dozens more. He looked up the letters until he was sure he had all the information on them. That's not true, he admits to himself, but he knows a lot more than most. He can do a few things to get that power exchange here. He watches her undress as he sits on her couch. He needs to make himself appear big; one method of letting her feel submissive is to remain dressed while she's naked, even while giving her pleasure. He's done this before, watching her stand and kneel naked, admittedly, it arouses him too. He can also make her do chores as well, while he does nothing, almost like a servant. He can take her apart through stimulation without letting himself succumb, like giving her oral pleasure. He doubts he can take her without falling apart as she does.

He has already denied her orgasms, given her punishment and chosen clothing for her-well colors-but the point is there. Without knowing it, they had been living parts of this lifestyle already.

"Dishes." He says and he works on loosening the binds on the rope while she cleans up the kitchen area. He likes this. He likes knowing she won't fight and push him anymore. Oddly enough, that's what has allowed him to make the most progress towards her. Ironic. Sheldon is reminded of the Chinese finger trap. He smiles as he hears the running water and unravels the rope. He leaves to freshen up, washing his hands, brushing his teeth and making sure his hair is in place, and then stops in the bedroom before he heads back. His little lady's bed is made and is neat. He likes it. He can tell her what to do all day and she wants him to. It's astounding to be on the same wavelength. He nods to himself as he walks back to the couch. The dishes are done and the table is clear and Amy is standing naked and biting her lip. She shifts on her feet and Sheldon employs one of his greatest weapons.

"Good girl." He watches her body tell him how she loved those words. He imagines Leonard and Penny think he knows nothing about sex, but it is all very simple and very telling chemistry and biology. While he knows neither of them like his one true love, physics, he knows enough to read dilated pupils and erratic pulses. He can play Amy like she plays her harp. He always remembers what she likes.

"Go freshen up for me." He doesn't smack her ass as she passes, mostly because she is expecting him to. He loosens his tie instead and grabs the rope once she is out of visual range. His options flash before him like a movie reel.

He can tie her to the bed and use oral stimulation.

He can tie her hands together and lean over her, visually reminding her he is fully dressed as he provides manual stimulation.

He could use both oral and manual stimulation.

He could tie her hands behind her back and use manual stimulation against the wall.

He pauses at the sound of the water stopping.

What does he want?

He looks to her as she walks in; all washed up and naked and he wants her on his tongue. He remembers her taste and suddenly yearns for it again. He can smell her arousal like a perfume and swallows as he clenches his jaw. He watches her eyes follow his Adam's apple as she slowly moves forward. He doesn't stop her, his gentle nod encouraging her to sit on the other edge of the couch before leaning over to kiss him and the memory of their first kiss plays in his mind as he closes his eyes. Fascinating. Look how far they've come. He opens his eyes to see hers and a wide smile. Look what that little vixen has done to him.

"Bedroom, Dr. Fowler." He instructs and her eyes meet his.

"Yes, sir." And he clenches his fist and barely refrains from humping the air like an adolescent gone mad with hormones. He likes that too, apparently. She is his good girl and he is her sir. Huh. Fascinating. She may also have turned a phrase into an aphrodisiac.

He follows her into the bedroom and places a hand on her hip to still her movement once she's gotten close enough to her bed.

"If you feel any numbness let me know right away." She nods and Sheldon begins to wrap the rope around her wrists. He can feel the increase in pulse and hear the breathing change so he places a gentle kiss on her shoulder. Amy is so small when he's wrapped around her like this; his front to her back, his arms around her to bind her wrists together. She could get lost in how precious she feels.

"It's all going to be alright Amy, Is this okay? Do you trust me? Does this feel okay?" She nods to every question with a slow exhale and Sheldon is surprised to see her eyes close as all the stress seems to vanish from her body.

"Amy?" She hums gently in response and Sheldon kisses her shoulder again. "How do you feel?"

"Good." She answers. "Nervous." She smiles as she pulls her hands a bit. "Helpless."

"You know you don't need protection from me," he reminds her as he wraps his arms around her and she playfully moves her fingers against his pants. He hardens in response and she shifts her hips.

"Behave." Sheldon warns as he turns her and leads her to the bed. He backs her into it and she sits on the edge of it. Their height difference is very pronounced at the moment so Sheldon puts his hands behind his back for extra emphasis.

"You are not to cum without my permission." Amy nods and Sheldon tilts his head.

"Yes, Sir." He does like it. He's going to make her say it often.

"You're going to be a good girl and ask for it."

"Yes, Sir!" She wriggles on the bed, her anticipation building and Sheldon can barely refrain from taking her now.

"Spread your legs." She does. "Lay back." She closes her eyes as she does so and he very lightly slaps the right side of her knee. "Eyes open." She opens them. "You're going to watch."

Sheldon pauses as he looks at Amy's form. He sees her epidermis but a single blink takes him down to the outlines of her skeletal system, the cardiovascular system. He glances to her breasts but she's her heart, the physical representation of them. Beating hearts. He feels his pulse in his neck and chest. It's fast and its harder. He moves her hands up, so that they are resting on the bed above her head and kisses her chest with closed eyes. She flexes her fingers as her hands hit the bed but she relaxes against him as he kisses her. The gentle pulse under his lips causes him to smile as he trails kisses down her body.

Amy whimpers at the feel of Sheldon's lips on her chest. At first she thinks he's going to move to her nipples but he immediately moves down her stomach. My heart she smiles He kissed my heart. Her man of logic and reason succumbs to sentiment for her, for romantic whims and lovely nonsense.

"I love you." She states as he places a hand on the hip his tongue draws lazy circles on. He has to know, she's said it over and over again; she has kissed him with all of her and exposed the deepest parts of her. Sheldon has to know, he has to feel it, in his heart and soul, his brain must know. His lips must have tasted her love as they kissed her heart.

"And I love you," he says slowly, kissing her skin after each word, moving closer and closer to where she wants him and yet not close enough. The words she'd never thought she'd hear during an event she never had dreamed of made her just want to embrace Sheldon and never let him go. "My little vixen." He moves up and takes a nipple in his mouth. He sucks briefly before moving away, his teeth barely scraping the nub and resulting in a sigh from her. "My good girl." The other nipple hardens under his tongue and he moves away to blow on it. Amy arches slightly and moans softly but Sheldon is content to tease her and Amy is content to lay down and take everything Sheldon wants her to, give just what Sheldon wants her to, because right now Sheldon wants her and its magnificent.

He alternates between building her up with licks and scratches and letting her cool down, but there is only so much he could do before he would actually have to move to oral clitoral stimulus. He finds himself with so many questions. He wants to know her every taste and smell during every part of this. He wants to hear every possible combination or moans, groans, sighs and screams he can make Amy produce as that final wave of pleasure hits her. He wants to know how many times she can, how many times she will let him. He wants his tongue inside of her so he can taste her pulse before it and listen to her breathe after it. Will she always react the same way or can he make her giddy, can he turn her into a lazy mess of satisfaction? He wants to plot the pinkness of her cheeks against her peaks and the time. He wants to account for all places and the time of day, the weather. What would be the most fun for her, ever?

"Dr. Cooper, please!" He shakes his head to see Amy pulling on her restraints with her head thrown to the side. She's panting and he can practically taste her. He pulls back to Amy's whine.

"What is it?" he traces her nervous system with his fingertips.

"Please Dr. Cooper, Sheldon, Sir, I want you to taste me!" Amy looks at him and she is a mess. Sheldon loves it.

"Good girl." His ideas change suddenly as he licks up her lips before settling on her clitoris to stimulate. He slides a finger into her and makes quick work of her first orgasm with her begging until he was sure any more would have him come apart in his pants. She is moaning around the pleas and Sheldon feels the pulsations around his fingers get stronger. When Amy climaxes the pressure on his fingers is enough to harden his own sexual anatomy and make him moan out in want and memory.

"Count to 60." He says and he uses the time to calm himself and spread Amy's juices over her stomach. She shudders. Her fingers twitch and her toes clench. He slips his finger into her bindings to check them.

"Nod if your hands still feel good." She does. "Good girl."

"60." She finishes and since she was told to watch she does, watches as Sheldon's face turns from gentle control to wild cockiness and passion and then the only thing she's aware of is that Sheldon's building her to another orgasm.

"Cum."

She is still shaking when Sheldon asks her to count again and she's so eager for it she rushes the number. The smirk on his face deepens as she hits it and he moves again, leaning over her and staring into her eyes. She can't move to touch him and that somehow makes this all more fun.

"No one else can do this to you." He suddenly growls. Only Amy does this to him and only he can do this for her. "You're mine." She moans and throws her head back at that. Sheldon bites her neck, hard and she arches forward Cumming hard. They both pause. Sheldon's fingers moving a bit before sliding out.

"You weren't supposed to like it that much." Sheldon pauses to look at the red angry teeth marks. "I didn't want you to stop looking at me; I correctly assumed it would get your attention."

"Got a bit more than that," Amy giggles "Hoo!" She looks up at Sheldon as he stares at the mark on her neck which has already moved from painful to dull throb. It reminds her of the spanking she received. Not the punishment, but the first one. She squirms.

"Does it hurt?"

"Not anymore. I'm remembering when you spanked me, that first time, after I pretended to be sick." Sheldon nods, moving to lie on his side and moving a hand across Amy's body. She's sensitive and would stop him but a pull on the rope had her blushing and stopping.

"That was a new thing, I'm not going to punish you for not ask-"

"No, not that." Amy gently corrects

"You want another one?" He guesses and she nods.

"Different than-" her throat dries at the memory. Her disappointment, their words, the pain.

"Shh," he soothes. "I understand." He thinks he does, but that's not important, what's important is not letting Amy settle on the negative.

"One." Amy starts and Sheldon smiles.

"Good girl." And Amy squirms on the bed as she begins her count, only this time she watches Sheldon undress and put on a condom. "slow down."

"32." She swallows as Sheldon moves over to the edge of the bed. "33"

He's between her legs and staring at her by the time she gets to 45. And at 53 he's rubbing himself against her lips and she's shaking.

"60." She moans as he slides into her. She moves to place her hands on his back but they can't separate and Sheldon uses a hand to hold down the rope and immobilize her.

"Good?"

"Good."

He shifts forward slightly so that her hips are angled and she lets out a rush of air. She has no leverage. She really can't move, there is nothing she can do right now but wait. She swallows.

"Amy?"

"Okay." She closes her eyes and Sheldon kisses her forehead. She smiles.

She was nervous before, but once Sheldon moved it was a different story. Every thrust pinned her down and every motion reminded her she could do nothing against it, and she loved it. This was Sheldon taking what he wanted from her. All Sheldon. She smiles as she moans and Sheldon finds himself drawn to the darkening spot on her neck. Anyone who sees that would know, without a doubt, what happened. They'd know it was Sheldon who did it. He groans and kisses it, causing Amy to clench around him tighter.

"Good?" He asks again just to be sure and Amy nods frantically.

"Go go go. More!"

Dr. Amy Farrah Fowler can use her neural knowledge to trap him in love and reduce him to the simplest of creatures, only worrying about sex and were rough, kinky sex at that

But Dr. Sheldon Lee Cooper was a physicist, and a master of the universe and he could use that knowledge to turn the other genius in the room to a cum drunk mumbling mess.

And he would.

Oh he would.
