Desire

She could hear Six's breath quicken and his body stiffen slightly. She had to wonder of his endurance with touching his shaft and she also had a thought, what did aliens do when they got "the urge"? That was something she'd have to ask him, but it wasn't the time for questions, that would ruin the mood.

She cupped the underside once more and moved in closer again, her breath fanning over the shaft in gentle waves.

Six didn't just hiss at the close proximity, he full on growled. He couldn't help it, whatever she was doing was driving him crazy and he'd be damned if she didn't finish him off with all of the teasing she was doing. He gasped and almost screeched as he felt something wet and moist rub against his shaft, was that her tongue? Whatever it was, it felt so good against his heated flesh. He felt vulnerability once more at the thought of her mouth near his shaft, although her teeth weren't as sharp as his, he knew that the flesh was easy to tear, even with such blunt teeth, if she were to clamp down and tug, he'd be done for, and so would she since he'd bleed all over her. He shook himself mentally at the thought; she'd never do that to him, would she? Nah, she wouldn't. With that decided, he tried to relax his body again, but found it difficult at the attentions he was receiving from the girl.

Sam trailed her wet fingers along the underside and sides, deciding that she'd like to see him all wet and bothered. She smirked deviously at her actions, knowing the sort of effect she was having on him. Her confidence was rising rapidly as she ran her hand up and down his shaft, slowly, surely tormenting the poor alien to the point of cracking, which she would be very to see. She couldn't imagine what he would do if he did in fact crack under the pressures she was placing on him.

She took her hands away and heard his sharp intake of breath as she spat into her hands, lubricating them to the point of him being a slippery mess when she was done with him. She wrapped both hands around his shaft once more, her hands moving from the base to tip. Gently, she pumped the heated, throbbing flesh and waited for him to finally break and possibly try and either dry hump her or force her to go faster. She paused at the feeling of something in her hair, and then realized that his hand was extended and pushing her head toward his crotch, telling her to put her mouth around it.

He knew she was playing games, so he'd just play right back with her, playing the submissive idiot wasn't always his forte, so he went to being the dominant in the relationship, as he'd always been. He felt himself snarl at her as she defied him by trying to push against his hand to say 'no', he then pushed with more vigor, her face pressed to his manhood in such a way that he found himself hissing at her in warning.

Sam looked to the side, looking at Six who was enjoying everything she was giving him. She smiled against the flesh and moved her head up the shaft a little bit; she then kissed the tip gently and felt the hand in her hair slacken slightly. She licked the tip, the hole at the top nothing like the slit she'd seen on pictures of human men and dipped her tongue in slightly before gently placing her mouth around it and suckling gently.

Six was waiting for that, her mouth was so warm and moist that he felt his orgasm beginning to build there. He hissed at her in warning, and felt her gulp down more of him eagerly which had him gasping and hissing at her. His jaws and inner teeth were clenched to the point of possibly breaking, and finally he let his mouth open and a roar escaped, very much unlike the screech he'd let out before.

Sam's eyes widened as she felt warm, no hot liquid enter her mouth and seep down her throat and gently gripped with her teeth, hoping that he wouldn't push her head down onto him more since she'd probably choke if he did. She was barely taking in the tip, only about a quarter of the length was fitting into her mouth, no maybe a little more than that, but she wasn't in any position to think about it since she had to swallow or she'd die anyway. She swallowed as much as she could and then let go of the shaft and backed away, the hand still gripping her head tight as she openly gagged on the taste, although it wasn't too bad, it was mostly shock.

When she calmed down, she ran her tongue along the inside of her mouth, tasting his cum which seemed to stick to the sides of her mouth. It was surprising for her since it tasted a little sweet, a little like icing sugar with a hint of salt; strange.

She looked up to Six who was lying there, looking sated, his member still fully erect as it had been before and shook her head in bewilderment. He had such a high sex drive that he could probably go on all night if he wanted. She blushed at that thought and bit her lip which tasted like his shaft did; like his saliva. It clicked just then, those lumps were glands that allowed him to give off his natural form of lubricant; aka, his saliva. She smiled at her find and wondered how she didn't notice before; she chuckled and crawled up to Six who was sitting up.

He sat up slowly, not really knowing what he was doing at that point. He tried to stand but found that his legs turned to jello and he fell back down, on the other side of the bed. He felt weight shift the bed and felt some hands on his back, stroking him since his back was to the human. He hissed his appreciation, and felt her hands kneed into his flesh, massaging him gently.

Sam stopped what she was doing and sat up against the wall by Six's head. She felt Six's tail move up her leg in a slow and sensual manner with a hiss of content.

He turned around and laid to face her, his head in her lap and he nuzzled into her thigh gently. His inner maw came out to gently nip at the cloth covered thigh while his hands went up and down her legs in a very sensual manner.

Sam flushed beet red at the attention, his hands were doing a number on her slightly aroused state of mind. From giving the alien a blow job and swallowing what he actually gave out, she'd felt the urge to just rub herself against the Xeno's length, and his hands were doing nothing to sate her wants.

Six was aware of her state of arousal, not only was the fact that her body heated up under his touch was a give away, but the fact that her scent was musky had him hissing in satisfaction. He was happy to be the one to make her so aroused, and every time he smelt it on her, it was just like new. She reacted the same, blushing and squirming under his touch, but for some reason, it all felt new when he was experiencing it. It was a strange feeling.

Sam was sat on the pillows with her back against the wall, she had no idea why she had sat up against it when she had comfy pillows and a nice mattress to lie on instead, that made no sense to her, and with what Six was doing, heat pooled in her belly and had her squirming. She could feel everything, from his tail which was inching up her thigh, tail blade running along her trouser covered leg gently, and his hands which seemed to be stroking her sensually. She was in heaven at that point, nothing beat having him touch her in such a way, nothing made her wet in the apex between her thighs.

Six sat up and sat on her left side before coaxing her to lay down with his hands, tugging at her clothing in a lie down gesture, well, that's what he was going for anyway, but what she did had surprised him. He watched as she smiled and shook her head at him with a roll of her eyes and removed his hands.

"Alright." She said while quickly removing her shirt to expose her pert breasts with nipples that were fully erect from all the attention she was receiving.

Six hadn't meant for her to do that, but he was glad that she'd taken it that way and quickly showed his appreciation by mounting her and tearing her trousers from her body with his tail blade. He heard her gasp and quickly covered her mouth with his drooling one, the heat of his passion showing in that one powerful movement.

Sam quickly threw her arms around the Xeno's neck and held him to her passionately; her tongue moved along his teeth and felt the smooth surface on her sensitive appendage. She moaned at the feeling and quickly laid herself down on the mattress, her head on the pillow as the Xenomorph moved from her mouth and down to her breasts.

He nudged at a dusky pink nipple and heard her moan loudly, he then got to work with using his inner maw to lick it gently, his other hand went up to play with her other nipple, tweaking and pulling gently. He felt her back arch into him, and suddenly thrust upwards into his crotch. He wanted to do what she did to him, but he was so afraid he would hurt her, her breasts were fine with his ministrations as they were made of tougher skin whereas the lower half was rather sensitive and with his teeth he wouldn't want to risk it. His fingers may be alright to use though, maybe his tongue if he kept it shut, maybe.

He moved his head to the other breast and wrapped his inner maw around that one to gently tub with his teeth, being very careful of the knife like objects. He then moved lower, his inner maw trailing large amounts of saliva down her stomach and pooling in her naval before moving lower again and to the apex between her thighs.

Sam felt the intent more than saw it and quickly clamped her legs shut, although she felt that it may be an offence to the Xenomorph, she didn't particularly want him to sever her most sensitive area.

"Six… W-wait." She stuttered as he nudged her legs apart and placed his massive head between them so that she couldn't close them anymore. She began to panic greatly, her head moving from side to side as her heart raced in her chest. "No Six, wait…" she told the Xenomorph.

He didn't want to wait; he really didn't want to, he wanted her to feel the same amount of pleasure as he did. He nudged at her folds with his larger jaws and rubbed his talon like teeth along the insides, he could feel and taste the natural lubrication and could hear the gasps of pleasure coming from the human being who was telling him to stop moments ago. She was enjoying it, and he wasn't about to stop. He pressed on, and used his inner maw to rub against her clit in a way that made her jump and cry out in pleasure. He felt himself growl low in his throat and had the urge to mount her properly, of course he'd wanted to before, but at that moment, he felt the oncoming urge to take her viciously and make her his once and for all.

With that thought, he stopped what he was doing and moved up her body again. He rested his hips on hers and pressed down to the point of his length being encased by her folds, the tip of his erection weeping and wanton sat just over her belly in its perfect arc. He moved his face close to hers and hissed to her with a tilted head, a silent question which he was hoping she'd respond to in a positive fashion.

Sam looked up at him with a shaking form, she figured that it was from all the pleasure he managed to make her feel in just moments and bit her lip at the silent question; 'can I take you?' She had two options; say no and just pleasure him like she had earlier, or say yes and have him enter her and possibly tear her apart from the inside out. Her being quite idiotic and daring nodded her head at him once and continued to look up at him with a worried expression. The answer to her earlier question of; 'would it fit?' would finally be answered.

With her answer, Six screeched in her face in thanks and nuzzled at her marked shoulder before nipping at the bruised flesh. He quickly positioned himself to indulge in the sweetness that he'd just tasted and the warmth that was sure to come and looked back to her with a hiss in her face and his forehead against hers in a loving manner.

Sam picked up on this and gripped onto his neck tighter than ever before, kissed him much more passionately than they ever had and quickly pulled away to pant at him, showing her eagerness at him doing what she thought was impossible.

He kissed her back as best as he could before gently moving forward and having his tip encased in the warmth and tightness of her body, he pulled back from kissing her and rested his head on her shoulder in a way to try and calm himself down, his heart was beating at his rib cage much like a new born of his kind would beat at a hosts chest to break free, and made a quick snapping motion with his hips to sheath what he could inside the girl.

Sam's eyes opened wide in shock and pure pain, she tried to cry out but nothing escaped her suddenly parched mouth. Tears began to form in the corner of her eyes and her hands had let go of Six's neck to come up to face, balled into fists and rubbed at her eyes gently. A sniffle literally echoed in the room as a new sense of tension entered the air of the room.

Six was still, he was so frustrated at that moment, stopping was the last thing that he wanted to do, but she was hurt and it was his fault, and it wasn't his intention. He stayed sheathed inside her and moved as little as possible as he slowly lifted his head up to face her, a hiss escaping his mouth.

Sam felt sobs rack at her body, sniffles escaping her mouth as she contemplated the question he was asking; 'are you okay?' She un-balled her fists and wiped at her eyes furiously, feeling stupid for crying at the most natural thing that she could do with someone. She looked up at Six who was looking down at her throat, his head bowed in submission. She sniffled again and swallowed the bile in her throat before reaching up to his head and stroking the side of his face which he leaned into and she smiled at him, knowing that he was sorry.

"I'm okay…" she said with a small sniffle, "just be gentle, okay?" she told him as she pulled his face up to look at him with watery eyes of love.

Six stared at her, was she stupid? If it was hurting, then you should stop right? He was certain that that was how it was supposed to go, since some of the other Xenomorphs tended to get hurt immediately, especially at the first time of mating. The barrier that there was to break, was something painful for his species, and clearly the same for a human being if the girls tears were anything to go with. He shook his head and attempted to pull back out, but she wrapped her legs around him, as much as she could with his tail anyway.

"Don't you dare." She threatened. "Just gimme a minute…" she said while gripping onto him with her arms as well, keeping them securely locked around his neck so that he couldn't move away.

Six let out an exasperated sigh at her words, he was guessing that he wasn't allowed to move away or she'd probably cry some more, so he stayed still. He laid himself down on top of her, being careful of his weight and nuzzled at her chin with his massive head in an attempt to show her that it was okay if she wanted to stop, and when her arms and legs slackened he was sure that she'd ask him to pull out, but no, she moved her hips instead. He hissed in pleasure and bumped at her jaw, telling her to keep still or he'd more than likely mate her into the bed. She did it again, and he almost came undone.

He pulled away from her arms, removing them from around his neck and growled in her face, warning her, challenging her. She did it again and that was the end of it. In a quick move he was out of her and flipping her over, nothing gentle about his actions. His lust was something that overtook him, and she was squealing as he thrust himself back into her again, and from on all fours, the pleasure was intensified.

Sam was in complete shock at the others actions, first he was being sweet, and then he just flipped. She tried her best to stay on her hands but every time he thrust into her, she felt heat pool in her stomach. She felt herself flush at the mere thought of what he was doing to her, her body heated up at the animalistic display.

Six continued with his erratic thrusts, not caring of her wellbeing anymore, but of his own pleasure, although he could tell that she was enjoying every second of it. He gave a smug smile and continued his thrusting; his hands on the sheets underneath the two and gripping them with such force that he was sure that he heard something rip. There was something about the way that she seemed to be thrusting back and into him, something about it made him lose all sense of control and he dug his teeth into the same shoulder as before which had her crying out in pain and pleasure once again. He was quite surprised that she wasn't fighting back since he knew that she liked her freedom, although she didn't like it when he just up and left her which he had done at times, and at a place like this, he couldn't blame her. Everyone was out to get his kind, and she was worried, nothing more. She allowed him just as much freedom as he did with her, even if he got jealous sometimes.

He gave a growl of satisfaction as he dominated her and as she attempted to get back up on her hands to become erect, he quickly pushed his body weight down to keep her there. She seemed to like that, being dominated; he'd have to remember that for the future. He screeched at the feel of her tightening around him, she was so very tight, nothing compared to his species. He felt her walls shudder around him in pleasure and he felt her spasm uncontrollably, her head turning to the side and her face splashed with tears. He stopped instantly for her to recover from whatever pain she was feeling.

She looked back at him and groaned at the erotic display.

"Why'd…. you stop?" she panted in question. "Don't stop…" she continued and tried to get up on her hands again, but was instantly stopped by Six who pushed her down and gave a screech in her ear.

He was about ready to cum, but was it okay to cum inside her? He hoped that she would be okay and not be impregnated with his young, although he wouldn't mind the concept of such a thing, her being a mother to his pups. He gave a massive roar as he felt his climax approaching rapidly, his body was almost there, all he'd need was a last bout of pleasure to get there. His thrusts became more maddeningly harder, which struck Sam in just the right place and she cried out.

She pillowed her head with her arms and quickly bit one in order to keep her voice down, although Six was being quite vocal and no one was unaware as to what they were doing, she certainly didn't want them to hear her. She felt it, her stomach uncoiled, she screamed around her arm and she felt herself black out.

Six arched his back and thrust in one last time, sheathing him wholly into her body and let out a massive screech of what others would deem pain, but to the two lovers, it was one of white, hot, liquid pleasure. He felt himself let loose in her confines and slumped over her body in exhaustion, he quickly averted where he was slumping and moved to the side, with her back to him, and still sheathed inside her.

He made an effort to quickly untangle the sheets from their limbs and covered her in them the most before allowing his self to fall asleep while still nestled in her warm body.

The two awoke some hours later to a brash knocking on the door, well, at least Sam did. She was quick to try and sit up but Six was making it hard for her with his arms caging her in and pulling her back to him. She gave a frustrated sigh and pushed at the Xeno's arms.

"Six, let me up." She told the alien with a groan. She could still feel him inside her, his length still out and profound. Wow, the guy was sleeping and his libido was still hyped, she'd have to keep that in mind for-

Another rap on the door, and this time, a voice sounded through.

"Sam, it's Lieutenant Jones, we're coming in." He told her as she quickly scrambled to cover herself and Six with the covers, herself more than Six since he didn't really have much to hide.

The door swished open with a hiss of hydraulics and in stepped the Lieutenant with Chris, Jodie and Simon in tow, and also two other soldiers stood behind the three with guns at the ready, rested on their shoulders and one chewing gum with attitude much like the elusive Lieutenant.

Lieutenant Jones looked about himself and smirked at his surroundings while chewing his signature gum.

"We heard a lot of noise coming from here and we suspected Six to have eaten you or carried you away." He told her with a smile. "We were concerned for you, Sam." He said in the sweetest voice he could muster. "But I can see…" he paused to quickly approach the two and went to lift the covers from the two bodies, but Six was fast.

Six shot up and dove on the other, his manhood half way sheathed while dripping with juices from both her and himself. He got right up close to the Lieutenant's face and hissed at him in warning, daring him to make a move.

The two at the door pushed past the other three to fire, but were stopped by a hand which went up and from the Lieutenant no less. Was the Lieutenant smirking? The man was damn crazy for even messing with Xeno, let alone the mate of one.

Lieutenant Jones gave a chuckle and shook his head at the Xeno.

Six tilted his head at this in confusion, his lips dribbling saliva all down the man's jacket.

"You're very protective of her, very good." He said while attempting to sit up, but was pushed back down to the floor by Six who was looking down at him with a hiss. The Lieutenant looked to Sam who was sat up while clutching the covers to her chest, obviously covering up her body from the rest. He turned back to the Xeno and rolled his eyes. "Okay, I'm not gonna hurt her, alright? Just get off of me." He said.

Six hissed at him one last time and moved back and off of him slowly, making sure that he wasn't about to try anything.

The Lieutenant stood and brushed himself off, and regretted trying because of the sticky mess on his flak jacket. He looked at the two and chewed his gum with a serious look on his face.

"I want you two up and ready to meet with us in fifteen minutes, understand?" He asked the two.

Sam nodded her head and watched as he made his leave.

Chris smiled and nodded at her.

"Meet us in the Main control room, alright?" he asked while waving as he moved to go out of the room. He stopped to look at Jodie who was gaping at Six in disbelief. "Jode?" He asked while waving a hand in her face.

She turned to him and pointed at the Xeno in utter shock.

"Did you see…?" she couldn't finish her sentence.

Chris nodded.

"Yeah, and I'm still trying to burn the image out of my mind, now stop staring like an idiot and lets go." He told the other with a glare before grabbing her arm and hauling her out.

Simon and the other two were still stood there and watching the two with both shocked and hateful expressions. Simon shook his head and clicked to show the other two to leave them alone, and they did just that by following the man out.

Sam and Six were sat there, even when the door closed, with confusion written all over their faces.
