AN: This chapter gets a little smutty, so if that's not your thing feel free to skip ahead…you might miss something very important though!

The next day Amy received a delivery of a bulky parcel tied up in brown paper and when she read the label on the outside, quickly hid it away in the spare room until she could unwrap it without Sheldon seeing the contents.

"Was that the door, Amy?" Sheldon asked as he walked back into the living room after visiting the bathroom.

"Yes, just a parcel that was too large to leave on the lobby table. Sheldon, I need a few hours in the fortress tonight…it's not because I want to get away from you or anything." Amy quickly assured her boyfriend after a worried expression flittered over his face. "I've just got a few last minute bits and pieces to finish off and you'll be heading over to Comic Central with the guys this evening anyway, so don't panic if you find the door locked…some things are better left as a surprise."

"Oh Amy, you know I'm not fond of surprises." Sheldon gave a little moue of distaste and Amy walked over to brush a soft kiss against his pursed lips, murmuring quietly against his mouth.

"Trust me, Tex…you're gonna love this one."

"Hmm…" Sheldon hummed against her lips and slipped his hand around her waist to pull her closer against him as he parted his lips to deepen their kiss. It was Amy's turn to hum as his mouth rubbed against hers as the kiss turned deep and lush, leaving them both a little breathless and flushed afterwards.

"Hoo…" Amy murmured as she slowly drew away, running her finger along Sheldon's slightly swollen lower lip.

"Hoo, indeed." Sheldon replied huskily as his darkened eyes gave away his desire, "Are you sure I can't persuade you to let me in on your little surprise?"

"Just a few more days and you will be able to see it for yourself." Amy slipped her hands into Sheldon's rear pockets and tugged him a little closer. He looped his arms around her waist and smiled softly down at her.

"I'm glad we decided to have a quiet Christmas at home this year, I know that we discussed spending it in Texas but I really wanted this year to be special for us."

"How could it not be? We're living together now and closer than we ever have been, it's going to be a wonderful Christmas, Sheldon and I can't wait for you to unwrap your present."

"Hmm…only if it comes wrapped in a silky peach bathrobe." Sheldon rubbed his nose lightly against Amy's and she giggled softly.

"Perhaps I will let you open that one a little earlier rather than making you wait until Christmas Day." Amy murmured teasingly as she withdrew her hands from his pocket to trail her fingers under Sheldon's t-shirt, hearing him utter a breathy giggle.

"Ooh…Vixen, we're supposed to be working today!"

"I don't wanna work…I'd rather do this…" Amy ran her fingers along Sheldon's waistband until her knuckles brushed against the light dusting of hair around his navel; she slipped the button through the buttonhole and hovered above the zipper as her eyes locked with Sheldon's steamy blue gaze. His hand moved down to cover hers as he pushed her hand into his pants, forcing the zipper to part as he wrapped her hand around his turgid length and squeezed lightly.

"Mmm…maybe I should wrap a bow around it and pretend it's my present from you." Amy murmured as she nudged Sheldon's hand out of the way and slipped her hand through the slit of his briefs until it was skin on skin contact. Sheldon hissed through his teeth as his hips jerked forward when Amy started up a gentle pumping motion of her hand.

"God…you keep that up and you can unwrap me any time you want to…Ah, so good!" Sheldon closed his eyes and leant his head back, giving himself over to the feel of Amy's small hand moving up and down his shaft. "I'm gonna…oh shit!" Sheldon's eyes flew open as he felt a sudden warmth enclose his length and he looked down to see Amy kneeling at his feet as she gently took him into her mouth. Sheldon's hands wrapped themselves in her hair as he needed something to hold onto as she started to nibble and suck more urgently. "Oh baby…yes…yes…YES!" Sheldon screamed from the back of his throat as he shot huge streams of his essence down the back of Amy's throat, he tried to pull back a little frightened that Amy would gag on the salty liquid but she gripped onto his thighs all the tighter as she swallowed it all down. Amy's head continued to bob slowly as she lapped up all of the stray pearls of liquid that coated Sheldon's shaft, her tongue giving him a thorough cleansing as she hummed her approval under her breath. Sheldon's fingers relaxed in her hair and slid around to cradle the back of her head as he continued to thrust lazily forward, enjoying the vibrations of Amy's throat whenever she hummed; feeling the answering tingle all the way down his spine. He was a little disappointed when Amy finally drew back her head, as he was still hard within her mouth, but when she gave him a slow wink and started walking backwards down the hall he immediately started to follow; both shucking off their clothes and leaving them trailing behind them as they raced toward the bedroom.

"Did you enjoy that Tex?" Amy murmured huskily as she peeled off her blouse to reveal her pale pink bra. Sheldon stepped forward as he wrestled his t-shirt over his head, and his hands came up to start massaging her plump breasts in his hands; pushing them together so that they over spilled the cups.

"You have to ask? Amy, that was the most intense experience of my life and I loved it…" Sheldon squeezed the plastic clip of her bra together, releasing her bounty from their tight confines and giving a sigh when her breasts spilled out into his hands. "I love it when they do that, all soft and warm; and fitting perfectly into my hands." He rubbed his cheeks between the valley of her breasts, giving each one a brief kiss as he slipped the straps down and off her arms.

"Let's not forget the fact that you have large hands, so therefore my breasts are a little on the large size…" Amy stepped away briefly to hook her fingers in the banding of her briefs and again Sheldon's fingers nudged hers out of the way so that he could take over the task.

"Your breasts are perfect, as are your thighs." Sheldon trailed his palms over her silky skin as he pushed her briefs down her legs. "Your skin is so soft and when your legs wrap around me and hold me inside...it's just perfect and I never want to leave."

"Are you trying to seduce me, Sheldon Lee Cooper?" Amy asked with a soft grin, and Sheldon looked up from where he was worshipping at her navel, kneeling at her feet with his hands on her thighs.

"Why, is it working?" Sheldon grinned back a little wickedly as his fingers moved around to lightly start up a gentle caress of her inner thighs, drifting slowly upwards as Amy's legs parted to allow him greater access. "Oh my, what do we have here?" Sheldon's drawl came out a little husky as his fingers rediscovered the hidden pearl of her desire, slipping inside her slick walls to roll it between his fingers. His left hand nudged her leg to hook over his shoulder and Amy balanced herself by resting her hands on his strong forearms, something she was grateful for as his dextrous right hand went exploring further. "Hmm…that's new." Sheldon's long forefinger brushed up against a particularly sensitive patch of nerves and when he felt Amy shiver at his touch, concentrated his efforts there; sliding his fingers in and out slowly at first and then increasing in intensity when he felt her moisture pooling.

"Sheldon, please…I need you."

"Tell me what you need, love…I'm here." Sheldon added a third finger to the mix, stretching her walls slightly as gave them a little twist and flicking his index finger at the newly discovered spot.

"Make love to me, please." Amy begged, clamping down on his fingers as her hands bent into to claws; the sensations were incredible but it couldn't come close to matching how perfect it felt when Sheldon was inside her.

"Oh darlin', I'm so hard that I'm afraid I won't be able to be gentle with you."

"Then don't be, I need you so much." Amy was almost crying as she pleaded with Sheldon, and he withdrew his fingers slowly; his gaze almost feral with intent as he backed her onto the bed.

"You shouldn't have said that." He growled as he pushed Amy hard down onto the mattress and climbed up her body, rubbing himself over her with every movement.

"Why?" Amy whispered as her hands roved all over his back, coming to rest on his taut buttocks and urging him against her heated core.

"Because I'm now going to fuck you until you see stars…I warned you and you didn't listen…Now you have to pay the price." Sheldon forced her thighs to part even wider and without ceremony shoved himself deep inside her until he couldn't go any further. Amy let out a high pitched wail as she felt the tip of him brush up against the entrance to her womb as Sheldon started thrusting. He showed her no mercy as he withdrew almost completely and slammed in hard, feeling his scrotum slap against her buttocks with every relentless thrust.

Amy wailed and thrashed her head against the pillows as she felt every steely inch of him moving harder and faster inside her.

"Look at me." Sheldon ordered in a low, gruff tone. "Keep your eyes open, I want you to see who's fucking you." He moved Amy's hands above her head and ordered her to keep them there, the movement thrusting her breasts in the air. He dived his head down to suckle strongly at one breast and then the other, and when he felt Amy's internal walls ripple around him; bit down lightly on her nipple and she screamed his name loudly as she felt herself fall over the edge of the precipice. Sheldon released her nipple from his mouth and slammed his hands down either side of Amy's head as he raised himself up on his elbows slightly as started to thrust more erratically.

"Come on…yes, that's it." Sheldon muttered under his breath as he felt a tightening at the base of his spine, warning him that his climax was near. He could feel the sweat pouring off him as he continued to pound into Amy, making the headboard slam against the wall with every thrust. Amy was still screaming as she continued to climax around him and he could feel her walls tightening their grip around him and it was enough to start tipping him over the edge.

"FUCK!" He roared as with one last slam he gave him over to sensation, biting down hard on Amy's neck as he sent hot floods of liquid gushing into Amy's core. His hips jerked as he continued to spurt, feeling her squeeze every last drop out of him until he was wrung dry. Completely exhausted, Sheldon slumped over Amy's prone body as they both continued to pant heavily.

"Sorry, don't know what came over me…I can't believe I spoke to you like that!" Sheldon muttered as he feebly attempted to roll over to his side, cradling Amy against his worn out body. "I think I pulled something in my back…"

"Sheldon, that was so…"

"Disgusting? I'm sorry, it won't happen again, I promise."

"No! I was going to say that it was completely hot! You were like an animal and I loved it…" Amy wrapped her arms around his waist and nuzzled her head against his neck, lapping up the little beads of sweat that formed there. "I love it when we take it slowly, but I could live with it if you did that every once in a while…"

"Noted…" Sheldon dropped a kiss to her cheek and then frowned when he saw the angry red mark on her neck. "Oops…I think I gave you a pretty nasty hickey there, it might be difficult to cover that one up."

"Don't worry about it, I'm pretty sure I scratched some deep furrows on your back when you were going wild…maybe that's what is sore."

"Hmm…" Sheldon craned his neck around to try and see the damage, and then shrugged it off. "No real harm done. Can I just say that I loved my Christmas present?"

"You are more than welcome, Doctor Cooper…I loved mine, too."

"Oh, that wasn't your present…wait a minute." Sheldon rolled over in bed to rummage through the pockets of his trousers, glancing behind when he felt a soft hand squeeze his taut behind.

"Sorry, couldn't resist…it was just there and you know how much I love it."

"It is aesthetically pleasing, even I have to admire how it looks in a pair of tuxedo pants." Sheldon grinned as he bend over the edge of the bed once more, deliberately wiggling his behind in the air and hoping that Amy would cop another feel. "Mmm…I love your hands touching me. Just saying that it's right there if you wanted to move your hand a few degrees north…"

"In your dreams, Cooper…I'm too tired for another round just yet, I'm still recovering from what happened the last time."

"Meany…maybe this will change your mind." Sheldon finally laid his hand on the prize and rolled over to his back, keeping his hand tightly closed to hide the contents. "You're not the only one that's been on the receiving end of a few mystery parcels this week. Do you remember a certain conversation we had in this bed just a few weeks ago?" Sheldon opened up his hand to reveal a small box and Amy's breath hitched in her throat.

"Sheldon?"
"I love you, Amy and I want to wake up next to you for the rest of my life." Sheldon knelt on the bed and clasped her hand in his, reaching over to flip up the lid of the velvet lined box. "Meemaw helped me pick it out a few months ago, she was keeping it safe until I was ready…Amy Farrah Fowler, will you make me the happiest man in the universe and agree to be my wife?"

"YES!" Amy squealed and threw herself into Sheldon's arms, sobbing against his shoulder. "I love you so much."
"And I love you." Sheldon wiped away her tears with his thumb, and held up the ring. "Shall we see if it fits?" Amy held out her trembling hand and Sheldon slid the ring over her knuckle, admiring the way the diamond sparkled against her pale skin. "A perfect fit for a perfect lady."

"I'm not perfect, Sheldon, far from it." Sheldon placed his finger over her lips to prevent her saying anything further.

"To me you are the very definition of the word and I don't want to hear another peep from you unless it's 'yes, Sheldon'. Okay?"

"Yes, Sheldon." Amy smirked at him and Sheldon tapped her nose playfully. He flung the empty box onto the bedside cabinet and rolled Amy beneath him, pressing a kiss to her lips, raising an eyebrow in question.

"Yes, Sheldon." Amy nodded obediently and Sheldon grinned as he dropped a trail of kisses down her neck. "Yes, Sheldon." Amy murmured as his mouth moved lower and lower, until finally she was incapable of remembering her own name, never mind his…
