What is Wanting if One Cannot Feel?

*Got some lemony goodness in this chapter!*

They learned something new every time they looked at something in the Engineers database. One day while David was configuring their coordinates, Elizabeth came running in, completely out of breath. "David, come quick!"

Startled, he leaped out of the piloting chair and took hold of her as placed her hands on her knees. "What's wrong, Elizabeth? Please take a deep breath."

She coughed a few times before getting her breathing back to normal. Standing up straight, she greets him with a big smile. "I've been looking over the history of some of the Engineer's findings and...nevermind, come on!" She took his wrist and led him down the hall down the halls to the east end of the ship. Tapping away at the buttons in the same fashion he taught her opening the doors into the archive room that they'd discovered earlier. "Now look at this." She pulls him over to one of the larger monitors. She started typing away on the gel keys. "As you've seen before, most of their annals are recorded digitally. But I found these fossils here that they kept in a separate compartment." She pressed another button and a small compartment opened up, revealing a clear glass box. Then she grabbed one of the said fossils and showed it to him. "See? It has a similar skeleton to that of a fish on earth, but its bone structure is different. I thought it might have been a specimen from earth." Her finger traces along the bone. "So I put it in here to verify." she places it gently in the box, shuts it and it slides back into the compartment. "And watch carefully as the computer analyzes it. It's not only scanning the bone but the fossilized dirt too!" The monitor starts to beep and she looks at the results. "Now I'm still not entirely familiar with their readings as you are, David, but if I'm correct, this is the exact age of the fossil." She points at the screen. "It predates even the oldest fossils in record history."

David looks at it in awe. "You're analysis is correct, Elizabeth. This fossil is over ten billion years old."

"Do you know what that means, David?" She asked him with excitement.

He nods and looks at her. "Yes, it means that it predates our entire solar system." Leaning in to look more closely. "It's quite possible that this might have been one of the first species in its existence. Making it a direct ancestor to our engineers."

Elizabeth covered her mouth choked back a sob. "It's so... unreal . David this might be a key to the entire universe's existence. The Engineers hold the answers. I just know it. Oh, David!" She wrapped her arms around his waist and buries her face in his chest. "One of the greatest discoveries of all time and we're the first to have proof that it exists."

David smiles at her for including him in her findings. He responds to her warmth be pulling her closer and holding her in his arms. "It is a miraculous discovery, Elizabeth. You've managed to surpass all human science. Farther than anyone in history. All on your own."

"You wrong." She said muffled against his chest. Her head lifted and he looked at her thoughtfully. "I couldn't have done any of this without you, David. None of it would have been possible. It was impossible for me to get off of LV-223 on my own." Her gaze dropped. "I was so cruel before. When Charlie died I lost all hope. I was angry, hurt...and I took it out on you. Because it was easier than realizing it was my own selfishness for finding God that got him killed. This made me no better than Miss Vickers."

"No," He lifted her chin up with his finger. "You mustn't blame yourself, Elizabeth. Dr. Holloway wanted to learn the truth as much as you did. Space travel is dangerous under any circumstances. He knew the risks." He wiped away a stray tear that escaped her eye. "You are not wrong for being angry with me. I am the one they made him meet his demise in the end. Though while I felt no real loss for him, your emotional pain was regrettable."

She blinked away a few more tears. "It was another thing Charlie and I saw differently on. Treatment of Artificial Persons. While he saw your kind for what you were, I saw you for what you looked like. Human." A harsh sigh came out of her and she backed away. "But you're not." She backs out of his embrace and takes several steps back. "It's wrong of me to forget that."

What could only be described hurt coursed through his circuitry? But he held firm and followed her slowly. "On the contrary. It was your behavior towards me that made me feel more than what I am. I have no soul. But you make feel like I could have one. There was a reason that I enjoyed watching your dreams, Elizabeth. It was because of your love for life. Your parents. You find a purpose in everyone you meet." He took a step closer. "You make me feel as if I have potential beyond my initial creation. You make me feel, Elizabeth." Once he's close enough he moved a strand of hair out of her face. "You make me alive. "

Her dark eyes search his with uncertainty, but she doesn't back away. "Is it even possible...for you to feel?"

He rests his hand on her cheek, staying as close as she'll allow. "I told you before that 'want' was a concept I wasn't familiar with. But I am now. And what I want is you." He closes the remaining distance between them and presses his lips to hers.

Her lips are soft under his. He'd felt them once under his fingertips when he was examining her on the Prometheus. Once he'd read psychology texts that kissing was a form a test. A way to see if the partner could be a potential mate. He'd seen the kisses that she and Dr. Holloway snuck when they thought no one was looking. It made him curious. Envious. Miss Vickers never kissed him when she took him. He theorized it was because she didn't see him as a mate. To see the emotion behind their lip movements with Elizabeth and Dr. Holloway made him want to feel the significance himself. An android cannot breed. So they have no function that requires them to have a mate. But Elizabeth, makes him want to be hers.

She doesn't respond at first. Which could be either a negative or positive response, so he takes it a step further. He closes his eyes and takes her face in his hands as he urges her to open her mouth. She gasps and he takes the opportunity to slip his tongue passed her lips. He may not be human, but that didn't mean he couldn't replicate their movements. His tongue included.

She moans into his mouth as her tongue strokes along his. Her hands slowly sliding up his ribs and slipping around his back to wrap around his shoulders to pull him closer. Their bodies now molded into one.

We fit so perfectly together. David thought as he continued moving his lips with hers. She was so different from other humans. As he was different from other synthetics. Neither of them belongs with their own kind. Being blocked from their true potential. She is the ideal mate for me.

Elizabeth pulled away from him only to catch her breath, but David kept his lips on her skin. First at the corner of her mouth, then her cheek, her chin, below her jaw, and then up and down her neck. Her responses to him were a positive reaction. She was becoming aroused. Her skin forming goosebumps, her heart beating faster and her eyes were dilated. Yes, this was the correct response he wanted.

He kisses up her neck and licks behind the shell of her ear. His voice a gentle whisper, "Elizabeth, I want you. Will you let me have you?"

She sighs in bliss but shakes her head. "No, David, I won't do that to you. It's not right. I will not use you that way."

He bites her earlobe and she gasps. "You won't be doing anything I don't want you to do, Elizabeth. Say, yes. Don't deny yourself for what you desire." Her resistance was getting weaker, he could feel it. "Let me make love to you."

Her fingers have slid up his neck and tangled themselves into his hair. She resists for a little longer, and then she relaxes, "Yes…"

With great speed, he pulls her up into his arms and takes her to one of the bed chambers. He sets her down gently on the floor and she backs away gently. Her eyes stay on his as she first takes off her makeshift robe, letting it slide from her arms onto the ground. She then slips her shirt over her head, leaving her in only her intimate things.

David is silent as he watches every inch of skin reveal itself. So creamy in color, silk to the touch. Yes, he would touch it soon. Professional boundaries would no longer hold him back. She is offering herself to him. He will cherish this. Her wound had healed considerably since they boarded the ship. He'd already removed the staples since the wound was closing on its own. Now only a pink line remained.

Her knees hit the edge of the bed and she sits down gently. She pulls herself farther onto the mattress, her shallow breathing making her breasts rise and fall.

First, he takes off his boots, their thudding sounds echoing in the room. He takes hold of the zipper at his throat and pulls it down to his right. Elizabeth's pupils dilate even further as he pulls his arms out of the suit, revealing his bare chest. His physic mimicked that of a man in good physical shape. Though artificial, it brought the attraction to female women. Many a time had he'd notice them ogling him when he was present and board meetings alongside Mr. Weyland. He sometimes he found it a nuisance because they would often distract him from his duties. Today he was grateful for his design.

Elizabeth's mouth opened slowly as he slid the suit down the rest of his body. Her eyes following every movement, widening as he steps out revealing his girth. He slowly pads over to the bed, letting her take in all of him. Lifting one knee at a time, he crawls onto the bed towards her. As he gets closer, she lies down on her back. Soon he's leaning over her on all fours. His arms on either side of her head with his legs over her waist. He leans down to peck her on the lips. Just a small one. Then another at the column of her throat. He traces her clavicle with his fingertips, then her breasts. In response to his touch, her pink nipples harden and get darker in color.

His fingers travel between the perfect globes down to her healing scar. He traces it gently before giving it a gentle kiss along the line. She blushes at his tenderness; making him smile. He continues his kisses down to the line of her panties. Reaching up with his fingers, he looks at her, silently asking for her permission. She nods and he proceeds to pull them down her hips, up her legs, and off her feet. She shivers; either from the cold or his stare, he does not know. She was completely bare to him. Mine.

David settles himself between her legs and spreads them apart. Her breath catches as she sees him staring at her most intimate area. Unable to take it, she turns her head to hide her face, unwilling to show him her now reddening cheeks. He strokes her knee softly before nuzzling it, brings his lips down her leg presses a kiss to the inside of her thigh. He leans in at the apex of her thighs and kisses her clitoris. She gasps from shock and her head falls back, making him smile. He then takes a tentative lick along her labia. With no sense of taste, he can not detect anything in particular from her fluids, other than what he is doing with his tongue is helping her lubricate more.

At some point, her fingers are tangled into his hair. Her nails scratching his scalp as her moans get louder and louder with every stroke of his tongue. Licking up and down her entrance while taking special care of the bundle of nerves at the top. She lets out a yell of bliss when he takes the little bud with his lips and stuck strongly. So...swollen and sensitive. This was good. Elizabeth was very aroused and it was all thanks to him.

Once he felt she was sufficiently lubricated, he pulls away and slips his finger past her folds and strokes her opening. Her natural juices coating his digit as he teases her flesh. Then she lets out a guttural moan as he slides it into her flesh. Her hips quiver as he moves it slowly in and out. Her slicked flesh quivering as he enters a second finger. He moves his fingers in a 'come hither' motion. Using the pads of his fingers to stroke her smooth flesh as he finds the small bump inside of her cavern and her pelvis clenches. There. "Is this alright, Elizabeth?"

She nods shakily. "Yes...please don't stop."

He smiles and continues to move his fingers inside her, rubbing the small spot. Picking up the speed ever so slightly. Then with his thumb, presses down gently on her clitoris. Both digits striking her nerve endings with intense pleasure. Every so often she would wiggle her pelvis as he intensified the pressure. While one hand continued to stroke her nether region, the other occupied itself by stroking her breasts and tweaking one of those rosy nipples. Her fingers were curling into the blankets. Those well-sculpted breasts rising and falling with every breath she took. Her physic was exquisite. Everything about her was. Even the little mewls of pleasure that would escape her lips.

He pulls his fingers out from her heat and crawls back over her. Looking down at her flushed cheeks and now-longer her spread around her face like a dark halo. He leans down and probes her mouth open with his tongue and she sighs in bliss as she tastes herself on him. "Open your eyes." He commanded her gently. She opens them slowly and those brown eyes looked deeply into his. So dark. With her dilated pupils, they looked almost black. Pools of ink. "You are so beautiful." His hands slip under her back and pull her up against his chest. Proceeding to bring her onto his lap. Her eyes widen at his boldness and wrap her arms around his shoulders to steady herself. Again her stare land on his girth and she takes in a shuddering breath. She meets his gaze, and with his encouraging nod, lowers herself onto him. He slides in slowly, from the tip down to the base until he is completely engulfed in her heat. Her breath catches and she hangs her head back. Her breasts brushing against his pectorals as she leans into him.

He's the first to make a move. His pelvis thrusts into her slowly, making her moan. He does it again. And again. Soon enough, she's rolling her body in sync with his. Her legs tighten and she crosses her ankles behind his back, pulling him closer until they're practically molded into one organism. Bringing him in deeper. Once certain she's comfortable, he activates the vibration in his nether regions. She gasps in surprise and her eyes widen with shock. Her nails digging into his skin with the new sensation. He can feel her pulse quickening under his fingertips and moves faster. His thrusts meet hers with more intensity. Her arms tighten around his neck. Her breath was coming out in short pants with every thrust. Just a few more and she's screaming out her climax in his ear. The sound makes him fall through with his own version of an orgasm. Ejaculating his synthetic fluids into her womb. For a moment he let his circuitry imagine that he was actually filling her with his seed and bearing fruit. But just for a moment.

Elizabeth falls limp in his arms, exhausted and out of breath. He lays her down gently and pulls the blankets up and over them both. As soon as he lies next to her, she lays her head on his chest. Atop where she could listen to his manufactured heart. Neither of them said anything for a long time. At one point, he'd wrapped his arm around her and started tracing the patterns in her skin on her back.

After several minutes, she looks up at him. Her eyes dreamy. "That was spectacular."

He smiles and kissed her forehead. "I'm glad that you enjoyed it, Elizabeth."

She bit her lip self consciously. "I noticed that you released inside me. Did you…?"

"As a robot, I am unable to feel sexual gratification. My discharge was merely a simulation built into my programming for the release of my partner. Which can be done at any given time." Her lids lowered but he lifted her chin to look back up at him. "But witnessing your sexual release at my hands has brought me great joy."

She smiled shyly and ducked her head into his chest. "Even when describing sex, you make it sound like an algorithm."

"Does that trouble you?" He asked, already considering to backtrack.

"Not particularly." She murmured, pressing a kiss to his pectoral. A small sign of affection that didn't go unnoticed by him. "It just reminds me that you are unique."

"But not human." He finished for her.

She didn't respond at first. Her thoughts traveled for a bit. At last, she said, "No, you're not human. You're a robot. I know that and yet, I still feel drawn to you." She chuckled darkly. "Even though this goes against everything in nature, I don't care. I like being close to you."

He smiled and his hard drive computed the feeling of pride. "And I like being close to you, Elizabeth. I always have. You are unique in your own way as well, and it attracts me to you like a moth to a flame."

She smiled again and snuggled closer. "I'm so glad you're here with me, David. I don't think I would have made it without you."

He brings her hand to his face and kisses her forehead. "I love you, Elizabeth." She gasps and pulls away. She stares at him in shock, but he stays still. "I will not deny it any longer. Be this part of my programming or my own emotions. You needn't feel the same. But what I feel for you, I can promise, is real. I love you."

Tears gather in her eyes as she tries to fathom his words. For a moment he's uncertain of whether or not he's made a mistake. Then she sniffs and offers him a calming smile. "I love you too."

He blinks. His readings are...hopeful. "You do?"

She nodded and kisses him on the lips with less urgency, but full of compassion. "Yes. I love you, David. And I hope we get to be together for as long as possible."

This relieves of him of the possible tension he would have faced. She didn't reject him. She accepted him as her equal. They would never be able to truly bond. For they were two different forms of mechanisms. Hers happened to be organic to his synthetic. But it didn't matter. She loves him. Which is more than he would ever ask. She was now his forever...
