Title: The Proposal Copulation

Author's Note: This story takes place shortly after Sheldon's proposal to Amy in the season 11 opener, "The Proposal Proposal." It's basically pure smut with some fluff thrown in for good measure. Enjoy!

Something that surprised Amy about sex was that each time could be so different.

Their first time had been about discovery. Learning how to touch and be touched and how to communicate that information to one another. Learning what they liked and how they fit together. Slow and steady.

The second time had been a little more hurried. They had a year's worth of foreplay behind them, plus two interruptions by Howard and Bernadette's baby. They hadn't been able to get enough of each other.

The third time had been spontaneous and playful and a little bit weird; like them. Well, probably weird to outsiders anyway. For them it had been delightful and fun.

And this... this time would be different too; she could feel it. They had called their families and friends to share in the excitement of their brand new engagement and after they had made the last call, Sheldon had immediately turned to take her into his arms again. They had smiled at each other in pure giddiness before crashing together in an eager kiss.

And now, he was handling her so gently and tenderly. One hand was cradling her face as he kissed her with such reverence that it made her dizzy. This man loved her. He wanted to marry her, to be hers for the rest of time. She was grateful for his warm arm wrapped around her lower back, pulling her tight against him, otherwise she may have melted right off the couch into a puddle of pure bliss.

Suddenly, Sheldon stood from their spot on the couch, pulling her up with him but never breaking their kiss. He started walking her backwards, leading her to the bedroom of her short term rental. She went more than willingly, her arms wrapped tightly around his shoulders and neck, her fingers dancing through the soft hair at the nape of his neck, the hollows behind his ears.

The back of her knees bumped against the edge of the bed and she drew back, lowering herself onto it, even as her arms reached out for him. He stood, not following her down, his eyes gleaming in the soft glow of the lamp beside the bed.

"Is this okay?" His voice was soft, husky. Her heart rolled in her chest at the sound of him, so sweet and hesitant and aroused.

She couldn't believe she was this lucky. Sex with Sheldon, two times in one month and it wasn't even her birthday! She held out a hand to him and nodded. "Please."

He took her hand but didn't lower himself to her. He simply stared at her for a moment and she wondered what was going through that brilliant mind of his. She didn't have to wonder for long. "I want to show you how much I love you. How much I want you... to be my wife," he murmured quietly to her.

Amy smiled radiantly up at him, so pretty in the warm lamplight. She gently rubbed her thumb over the band of her new engagement ring, thrilled to find it still there. This was real. Her Sheldon. His Meemaw's ring. They were getting married! She felt she might burst with happiness.

Instead, she sat up, reaching out for him with her free hand, her fingers slipping under the hem of his Green Lantern shirt. "Show me," she murmured, drawing him down to her with her fingers looped in his waistband.

He went to her, letting go of her to brace himself with his hands on either side of her. He pressed a chaste kiss to the corner of her mouth, then used one hand to gently untie the belt on her fluffy white robe. He helped her out of it, then began short work on the white nightgown she was wearing underneath. Once it was pulled over her head and tossed somewhere to the side, she lay before him wearing nothing but a pair of simple cotton underwear. She reached for the hem of his shirt again, but he stopped her.

"Not yet," he whispered. "Scoot up."

Amy crawled backwards up the bed until her head found a pillow. She reached for him once more, but he evaded her, looping his thumbs in the side of her panties and slowly sliding them down her legs. She lay before him, completely naked and open. She felt a wave of warmth run across her body as she watched him watching her. His eyes were dark and dilated. A shiver of anticipation raced through her and she could feel her nipples hardening under his intense gaze. She had never been so turned on in her life; had never felt so desired as she did in this moment.

"You're beautiful," he murmured, running his hand up her leg.

"Sheldon..." She wanted him against her, desperately.

"Roll over."

Her eyes widened in surprise but she immediately followed his command, turning to rest on her stomach. She folded her arms under her head and glanced back to look at him, but he was moving over her, knees coming to rest on either side of her thighs. She waited in anticipation, dropping her head onto her arms.

His hands stroked her back, starting at the top of her buttocks and sweeping up to her shoulders in one long, slow stroke. She hummed and closed her eyes, enjoying the sensation. He gently squeezed the base of her neck where it met her shoulders, his thumbs digging into the muscles there. He started to massage her, using the base of his palms and his thumbs to knead her back.

Amy relaxed under his ministrations, certain she would have fallen asleep had this been any other day. She was melting, her body turning to liquid underneath him, but she wasn't tired, in fact, she was quite the opposite. His touch was lighting fires under her skin and she simultaneously never wanted it to end and couldn't wait for him to make love to her.

He sat back a little, his hands lowering to the top of her buttocks.

"Have I ever told you how delectable your posterior is?"

Amy squeaked a little in disbelief. "Really?" She wasn't used to Sheldon complimenting her physically. It happened so infrequently that it always surprised and delighted her.

He ran his hands over her cheeks and gave them a little squeeze. "Hmm. Incredibly so." Then he quickly leaned forward and pressed a gentle kiss to the round softness there. She shuddered. She couldn't believe her mysophobic boyfriend... wait... fiancé would do something like that. It was so hot.

Suddenly, she jerked when she felt something wet and warm on her lower back. His tongue. My God, she thought, as he trailed his tongue slowly along her spine, all the way up to her neck. She tried desperately not to squirm, gripping the pillow tightly in her fists as she let out a whimper.

He sank his teeth lightly into the side of her neck, then sucked the skin there to soothe it. She groaned. "Sheldon, please." She felt him grin against her neck.

"Please what?"

"I need you," she begged. She twisted then, trying to turn underneath him. He allowed it, then dropped his full body weight on her, pressing her down into the bed. She wrapped her arms and legs around him, clinging to him as her body involuntarily rocked up against his. Her head fell back and her eyes closed as she felt the rough seam at the front of his pants rub against her deliciously. She moaned, rocking her hips again. "Pretty please."

"Patience, little lady."

She groaned again, this time in frustration, as he pulled away from her to remove his clothes. She quickly moved up onto her knees, scooting towards the edge of the bed near where he stood. She reached for his belt buckle as he pulled his shirt over his head. Together they made quick work of his clothes, until he was standing naked in front of her. She was delighted to find that he was already hard and ready for her, just as she was ready for him.

"Lay back." His voice was hoarse.

Amy did what he told her, waiting for him to follow her and press his body against hers. Instead, he ran his hands over the tops of her feet, before he slowly started massaging her there. She watched him through hooded eyes as he leisurely made his way up her calves. She gave up then, closing her eyes and sinking further into the bed, surrendering to the feeling of his strong, warm hands caressing her.

Her eyes flew back open and she gasped softly when Sheldon's fingertips tickled the backs of her knees at the same time his lips landed on her left knee cap. It was such an odd sensation and she couldn't help but wonder how on Earth that could feel so erotic. She trembled as his hands slid up the backs of her thighs, pulling them gently apart, before stopping on her bottom. He leaned forward, his stomach and chest resting on the bed between her legs.

She felt his warm breath on her inner thighs and she shuddered when she realized what he was planning to do. This was a first for them and something she wasn't sure he would ever do. She reached down, her hand landing on his cheek.

"Sheldon, are you sure? You don't have to-"

He wiggled his eyebrows slightly and gave her a wolfish grin. "I want to taste you."

"God." Her voice squeaked in disbelief as she dropped her head back onto the pillow and grasped for the sheets to hold on for dear life. She wasn't sure she would survive this sexy, commanding version of her normally prudish partner.

"Mmm," he murmured as he gently spread her open with both of his thumbs. He took a long look at her, then leaned in, running his tongue from bottom to top in one fell swoop.

Amy let out a strangled sound, a mix between a gasp and a moan, then jerked when his tongue found her clitoris. He grinned against her and tried it again, just to make sure he in fact had the correct spot. Her hips jerked once more. And then again, because everything was better in threes.

"Ohhh," she breathed, and adjusted her hips, opening herself further for him. He hummed his approval against her and she shuddered at the vibrations.

His tongue made circles, then switched and went the other direction. She gasped and involuntarily pressed herself up against his mouth. He groaned and increased the pressure.

Her mind emptied, going completely blank. She couldn't decipher the shapes he was drawing with his tongue. She didn't care anymore. She could only feel. His warm mouth on her was like nothing she had ever experienced before.

She could feel the pressure building low in her abdomen already, as the muscles in her thighs twitched around his head.

Suddenly, his fingers were inside of her and she groaned at the sensation of being filled up, even as he brought her to ecstasy with his lips and tongue. After another moment, he curled his fingers inside of her, rubbing against the front wall of her vagina. She felt a hot spike of pleasure stab into her.

"Oh oh oh ohhhhh..."

His tongue flicked against her, once, twice, then once more, and her world exploded. Her whole body arched, then went rigid, as wave after wave of pleasure pulsated through her. Everything inside of her went white and hot and she could literally see stars bursting behind her tightly closed eyelids. Somewhere in the distance, she heard a long, low moan, and she would have been worried about the poor person making that noise if she had any brain cells left.

Finally, her body collapsed and she melted down into the bed, panting heavily as though she had just ran a marathon. God, she was so thirsty. She opened one eye slightly, expecting to see Sheldon's grinning face but he had disappeared. She heard water running in the bathroom and relaxed back into the pillows, closing her eyes again.

When she heard his footsteps, she croaked, "Water," but didn't bother to open her eyes. She heard him chuckle and pad back into the bathroom.

A few moments later, she felt his warm hand on her forearm. She opened her eyes and stared up at him. There was the grin she had been expecting.

She propped herself up on one elbow and reached for the glass of water. She gulped it down quickly, relieved to get rid of the desert that had taken up residence in her mouth. When she was done, she handed it back to him and he placed it on the nightstand next to her before crawling over her to snuggle into her side.

She looked at him with wide eyes. "Sheldon... I... You... God…" She shivered. "How?"

He chuckled and dropped a kiss on her shoulder. "I've been wanting to try that, so... I read just about everything on the internet that there was to find about performing fellatio."

"That was... incredible. I... didn't think you would enjoy that." She blushed.

"I wasn't sure I would either, but..." He pressed his erection against her hip. A thrill ran through her. "Seeing you like that, hearing the sounds you make, knowing I'm doing that to you... is very arousing," he whispered.

Her cheeks reddened even further. His honesty shocked her.

"Sheldon." Her voice was thick with emotion as she reached for him. Amy wrapped her hands around his shoulders and pulled him down to her for a long, slow kiss.

He reached up and combed his fingers through her hair, then slid his hand down her arm, leaving goosebumps in his wake. He moved inward and cupped her breast, then trailed his thumb over her nipple. It pebbled beneath his touch and he groaned. She arched into him and mewled.

"God, Amy." He slid his body over hers. "Wrap your arms and legs around me." She immediately did as he asked. They both moaned when his erection pressed against her wet heat. "Hold on to me."

Sheldon wrapped his arms around her back and shoulders and hauled them both up until he was kneeling. She gasped and held on tightly, willing to go wherever he took her.

He sat back on his haunches, then pulled one leg up in front of him, before doing the same with his other leg and rocking back on his rear end. Amy couldn't help but laugh. She felt like a baby marsupial.

His raised his eyebrows at her giggle. "What?"

"I'm like a koala!"

He grinned at her and gave her his best "koala face." She giggled again before pressing her lips to his. He adjusted them until he was sitting more comfortably in the middle of the bed.

Amy shifted her hips against him and the mood quickly changed as they moaned into each other's mouths. Sheldon reached down and cupped her bottom in his hands, shifting her back slightly. She used her heels to push herself up and reached down to wrap her hand around him. She sighed at the feel of him, soft and velvety around steel. Amy guided him to her entrance, and together they shifted until she sank down on him, taking all of him inside her.

Sheldon let out a deep groan.

"Oh, oh," Amy gasped.

He pulled back to look in her eyes. "Are you okay?"

"Oh yes." She felt her eyes rolling back in her head. She rocked against him, humming. "So full," she murmured.

"Amy." He wrapped his arms around her lower back, holding her close, then pressed his forehead to hers. "I love you."

"I love you." She flexed her hips, rocking into him again. In this position, there wasn't a lot of up and down movement, but he was so deep inside of her and when she moved against him, it stimulated her in the best way.

His hands dropped to her bottom, cupping her and helping her move, helping her rock against him. He pressed his lips to hers, sliding his tongue along her lower lip. She gripped his neck and shoulders, her arms holding him close, as a sob ripped through her. He pulled back to look at her and they gazed into each other's eyes, panting and swaying together, never stopping their slow, easy movements.

"Sheldon." She pressed her cheek to his and clung to him. With every roll of her hips, she felt a delicious tingle at the base of her spine. It felt so good. He felt so good. They were so close, their chests pressed together, their faces touching, but she needed to know that it felt good for him, too. "Is this… is this good, for you?"

He tightened his grip on her and nodded, unable to form any words. She kissed him again and felt tears welling up in her eyes. She had never felt so connected to him. This man, her man, wanted to spend the rest of his life kissing her, loving her. Only her. She had never been so happy in her entire life.

Amy cupped his face in her hands, pressing her forehead to his as they breathed the same air. The ring on her finger sparkled in the lamplight.

A tear slipped down her cheek and his brows furrowed with worry.

"Amy?"

"I'm okay." She smiled brilliantly at him. "Just happy. I love you so much."

Sheldon groaned again, moving his hands to her waist, speeding her up. She tossed her head back, arching into him and letting go. She just enjoyed the feel of him, the closeness, the connectedness, the pleasure. It built inside of her, higher and higher, threatening to overcome her.

"So close," she muttered, biting her lip in concentration. That familiar heat spread in her belly, growing more and more intense with each thrust of her hips. Her hands went to his hair, fingers tugging involuntarily as she rose closer and closer to her peak.

Sheldon grunted and sank his teeth into her neck as his hands pulled her down tight against him, stilling her movements. She felt his release pulsate inside of her and she ground down on him, once, twice more, then cried out as she tipped over the edge into her own wave of ecstasy.

They shuddered against each other, holding tightly as the pleasure crested up and over them. Her face was buried in his neck and his was pressing into her hair.

After a few moments, Sheldon pulled back to look at her, taking her head in his hands. They kissed, breathing heavily, then Sheldon shifted like he was going to move. She tightened her legs around him.

"Not yet," she whispered.

He stopped. "Okay."

"I just need a minute." Amy wasn't ready to give up the connection she felt to him. She stroked her hands over his shoulders and reached down with her left hand to twine her fingers through his. He brought their hands up to his mouth and kissed her knuckle next to the engagement ring. She smiled and blinked back tears.

"I can't wait to marry you," she murmured quietly, then wrapped her arms around his shoulders and gave him a squeeze. He ran his hands down her back, then returned her hug.

"And I you." He kissed her shoulder and then her neck. "I am glad you said yes."

She chuckled and pulled back to look him in the eyes. "Did you doubt that I would?"

He smiled and brushed her hair back. "Yes and no. I thought you would say yes but I was still nervous... especially once you found out Dr. Nowitzki kissed me."

"Bitch," Amy muttered with a scowl.

"Amy!"

She laughed. "You're my man. She knew very well you were taken and she made a move on you anyway. That is the very definition of a bitch," she stated matter-of-factly.

He chuckled. "Your man?"

"Well, you are!"

"And you are my woman." He wrapped his arms around her waist and fell back onto the bed, then rolled her underneath him again. He kissed her all over her neck, her cheeks, her nose. "My Amy." He growled playfully, making her laugh. "Mine."

"Yes," she breathed, capturing his lips with hers. "There's no one else for me."

He grinned down at her, then pressed a tender kiss to her forehead. "Amy?"

"Hmm?"

"Can we go shower now?"

She chuckled and pushed at his shoulders. "C'mon, fiancé, let's go get cleaned up."

End Note: My next story is going to be my first multi-chapter fic (for TBBT, anyway) and I've only written the first chapter so far. It may be awhile before I share it, because I want to be sure I can finish it before I post it. There is nothing worse than falling in love with a fic just to find out it's unfinished.

Let me know your thoughts on this story!
