Kendra sat straight up in the cockpit of the shuttle. After killing Kyne and leaving Isaac, there was only one thing she was concerned about. The Marker.
She considered herself fortunate that she wasn’t alone. By her side was another man. She wasn’t paying too much attention to him. With her current mission at stake, and especially after recent events, she wasn’t thinking about how sometimes her feelings towards her coworkers went way beyond professional. Right now the only thing she wanted was to keep this thing from fucking with anyone else.
For Kendra did not intend on fulfilling EarthGov’s mission. She didn’t think for a second they would be able to contain it. On the contrary, the more people this blasted thing was around, the more problems that would arise. If not by creating Necromorphs, then it would drive them batshit. That many people, that large and powerful an organization, the disaster onboard the Ishimura would look like a playground by comparison. She intended to destroy it.
Despite recent events however, she did feel better. It was bad enough seeing her dead brother. After seeing the horrors of the Necromorphs, it was good to have some freedom. But completing her current mission just left her with another problem. Namely, the man beside her.
She didn’t know anything about him. As far as she was concerned, he was just another man, like Isaac, like Hammond, like Kyne and Chen, someone she had to deceive and cast aside. For all she knew he could be a spy sent from Unitology meant to preserve the damn thing. Good luck talking to those zealots. The only thing she knew was that she had hired him as protection.
She didn’t know how to breach the subject without revealing herself. This close to her true task, she didn’t want to spoil her real mission. Fortunately he also had much to say.
“You okay Daniels?”
“What?” she said, a bit taken aback by the sound of that voice. She looked in the direction of it, right behind her. She saw and heard Isaac Clarke.
She was speechless. “H-how?”
“It wasn’t right leaving me back there like that. But I found a way, just like you said. And here I am. Now about you turn this ship back around. You do that, and I might forgive you. Make us whole.”
The chant of Unitology. She’d heard it plenty of times before. Hearing it now though, it had a new meaning. For once she was actually tempted to do just that. She had left him back on Aegis VII. As much as she hated doing that, she did what she had to do. Make things right.
But that wasn’t possible. He wasn’t real and she knew it. She only hoped he would survive.
She looked away from him and closed her eyes. As soon as she focused on those thoughts, remembered her dead brother, she looked back again. Nothing. He was gone. Just more smoke and mirrors from the Marker.
“Are you okay?” It was the man beside her. She turned around to regard him. He was nothing like Clarke or Hammond. Talk about meeting cutes, he was tall dark and handsome, he had a boyish smile that was definitely nothing like the disgusting Necromorphs that had laid waste to the Ishimura. His sudden appearance made her jump a little bit, almost like she was a little girl with a crush for the first time.
“S-sure...” she said. She still didn’t know much about him either. Was too flustered to even ask.
“I know it was a bit much getting this thing back so we get can get it to EarthGov, but don’t worry, we’ll be back soon. They’ll know what to do with it.”
That cleared things up a bit. At least now she knew how to handle this. Now she knew where he stood, who he was. She had handled Isaac and Kyne. She could handle this one all the same.
“That’s good,” she said, right now trying to save face and look like anything but some little girl needing some action. “My nerves are a bit on edge. My girlfriend’s waiting for me back home. I’ve been missing her for way too long.”
“In that case, leave the rest to me. I’m a mastermind when it comes to piloting a ship.”
Kendra blinked. She was suddenly possessed of the strange urge to say, I bet you’re real good at piloting something else too, she opened her mouth to say it without a care in the world, but stopped herself. It had only been at the last minute too, the idea of saying such a thing felt as natural as breathing.
She looked at him again. Big guy, short dark hair and totally jacked, she could tell that about him even with his uniform on. She wasn’t able to think straight, suddenly needing to find an excuse to get away from this situation.
It was her gut instinct that went beyond reason. Her gut was telling her something else too. That the wetness she felt in her pussy, the desire to see this man naked and find out for herself just how good a pilot he really was in other things, was not her own body’s reaction or even her own desire. That she knew it was a sign of the Marker fucking with her head.
Didn’t make that feeling go away. When she saw her dead brother, those feelings of strange nostalgia, of happiness, hadn’t gone away. This feeling was worse, because she knew it wasn’t a hallucination. She couldn’t just use her mind to rationally figure out this whole thing wasn’t normal.
And it was getting worse. As soon as she entertained the possibility that it was the Marker screwing with her head, Kendra’s mind was flooded with lewd and nasty images of tearing his clothes off and finding out what he looked like naked. Not only that, but she could only begin to imagine how big his dick was, wondered how many other women had taken a chance with it. Soon it wasn’t just a cute little crush, it was the kind of raging desire that the more she looked at it, tried to scrutinize rationally and argue away, the worse it got. However much she wished otherwise, she wanted him so bad and it wasn’t going away anytime soon.
“I’m going to get a rest,” she said. “I’ve just got a headache.” It took her an immense amount of willpower just to say that.
And that is what she said. But she didn’t believe it, not just in how it was an obvious excuse to herself, but also because she didn’t want to. She could hear how unsure her voice was, how husky her breaths were to her own ears, no way he didn’t hear that too.
More than anything, it felt wrong of her to say it. Doubting this desire now seemed so foolish to her. She bit her lip from how frustrated she was and it only made things worse. All she had to do was give in.
And that was exactly what she did. She climbed on top of his lap and cupped his face, it felt like the most natural thing in the world, it felt so right, and after all the recent misery of that last mission, that’s what mattered. The smile on his face made her heart flutter, he was so cute and there were so many ways she wanted to make him smile before the end. And she could feel the tent he was pitching in his pants right under her bum, he was so rock hard and that made her feel so wanted and made her want him even more. That big thing spoke to how much he wanted it more than any words.
And it silenced all the doubts in her mind. “This mission has left me feeling bad for such a long time.” Another unprompted thing that she would normally have never said after harrowing events as of late. But she didn’t dare fight it this time.
He slapped his hand on the autopilot button, and then they were on autopilot. The two of them made out on the spot, grunting and groaning as they embraced. They were holding each other and feeling each other up under their coats, his big hands touching her body excited her so badly, and she could in turn feel how big a guy he really was. Kendra couldn’t wait for him to start piloting her.
While they were sucking face, she moved herself back and forth on his lap. So resistant to the voices in her head before, now she was obeying them without a second thought, piloting him. Their tongues were flicking bad in each other’s mouths, he was feeling up her shirt and touching the bare skin of her back of her back for the first time and she had to throw her head back and moan like a whore. That only incensed him further and he kissed all over her neck. His hot breaths and touches excited her, after looking at the rancid Necromorphs too many times, there was nothing quite like being alive.
A wild wetness was stirring in her cunt. Her clothes were still on and her thick pants were anything but racy, and still she could feel that thick bulge, the heat inside of it. She wanted to fuck it up so badly.
He was licking and slurping all over her skin now. Kendra’s hands were erratic at that point, she was going nuts with the way she was caressing him, at first she reached down and rubbed her hands all over the big thing in his pants, moving it like she would a joystick even though the only thing she could feel was the head, that’s how crazed she was, and then something of reason returned to her. But it wasn’t advising her on the absurdity how quick and flurried this current course of action had become, it was telling her that if she really wanted to have her fun, she would have to put her hands someplace else.
She did just that. Kendra suddenly moved herself down off him on her knees and before him. He watched as she began unbuttoning his pants. For something so simple it was a bit of an effort at first, her movements were frantic and frustrated at once. But the moment was so heated that he didn’t try to assist her, he just watched her like he was watching a porno.
As soon as she got it right, his boner popped right out. It almost hit her in the face, and even then it might as well have. All she could do was stare at it, she had felt the impression of this prick in his pants, but seeing it in the flesh was another thing altogether. She might as well have been drooling at it like a repressed little schoolgirl getting a look at penis for the first time.
Contrary to how aggressive she had been earlier, Kendra tentatively reached forth and touched it like it was something forbidden to her. She almost jumped when she first touched his dick, she had barely grabbed him and in that time she could tell from that first caress alone just how thick and hot his pecker really was. Getting away from the Ishimura alive and being alone with this hunk of a man, she couldn’t believe how lucky she was.
She started jacking him off. Every time she stroked his flesh with her bare hand sent shockwaves of joy to the rest of her body. Along with the considerable heat in his manhood, she also became aware of the overpowering smell of his penis. While she continued beating him off, she closed her eyes and let herself become absorbed in it.
Against her body’s wishes and much to her disappointment, her mind returned to her. The thoughts of wanting him inside her, of fucking her up were still as strong as ever, but she could hear voices, annoying voices too in the back of her mind, telling her that she shouldn’t be doing this sort of thing, that it was the Marker’s influence messing with her. That she had an urgent mission beyond what this stud of an EarthGov employee would want, and definitely more than having herself a good time.
And yet she didn’t heed those warnings. Whether it was the Marker’s influence dominating her mind on a level she hadn’t anticipated or her own libidinous wants winning out against her sanity, Kendra didn’t stop. What she wanted, what she needed, was right here in front of her.
The scent of his prick felt like it was fogging up her brain. Focusing entirely on playing with his meat now, she became a little more skilled in beating his meat. Kendra had started brushing her fingers on the thick shaft before her like she was strumming it like an instrument while at the same time slowing the rate of her already awkward handjob just to make him feel it further. She felt his instrument in turn begin to tense up.
A giddy smile lit up Kendra’s face. Slowly she sped up the rate of her handjob while all the while continuing to playfully move her fingers across the expanse of his member, watching it react in real time like she was studying a wild animal. She giggled like a little girl, nothing appropriate or anything like how she would normally act in the present circumstances given what she had just gone through and even in that addled state of mind, she knew it. But that didn’t mean anything to her, the only thing that mattered was driving this big dick crazy.
He groaned hard when her thumb brushed up just right on the crown of his cockhead. Abandoning all restraint, she started beating him off at full speed. He threw his head back and cried out, she felt his whole body shaking, and the energy was coursing through in his dick. He was already packing some serious heat, but now she knew that he was really ready to fuck.
“That feel good,” she said in a heated whisper.
Not a question and he knew it. “Yes! Yes!”
“Good boy.”
Kendra had just the right idea to reward him. She stood up over him like a dominatrix and licking her lips, so confident in her sexuality and looking straight into his eyes. She was definitely resolute on doing more than just beating him off. The heat in her body was going crazy, and she went on getting her own pants undone. After the difficult task of getting his fly opened, getting her trousers off was a much simpler task by comparison, and it wasn’t long before her pants were slipping down her legs.
Kendra’s body had been getting so hot under her clothes. As the pants fell down to her ankles, it felt so good to have her skin exposed and open. He liked it too, Kendra had been mostly covered up but he could still tell she had a nice body under her uniform and her thighs didn’t disappoint. He couldn’t wait to see the rest of her naked.
Not as naked as he was. In a last attempt at defying the Marker’s influence, she did not take off her panties. He wasn’t even touching her but the pangs of want burning inside of her were like an inferno. She looked down at his penis, and she suddenly moaned out of nowhere.
Grinning to himself, he grabbed her crotch. She made another shrill little whimper from his big paws engulfing her nether regions. He crudely moved his palm over her pubic area again and again, and she fiercely grabbed onto him, there was no question the motion was violent. Not his shoulders, she grabbed his neck, and it was a clear sign of her frustration and powerlessness.
Kendra’s eyes looked dead and devoid of emotion. She was staring straight into his soul, and in any other circumstances he would have been terrified. But the fire in his cock was just as great, and it only inspired him to roughly caress her crotch even more. Her dampness was seeping through her panties and onto his palm, and her hot breaths were right on his face.
Before long she was sucking face with him again. Their mouths were hanging open, their tongues viciously pressing up on each other. She was grabbing his neck with a wild energy all the while, an attempt to contain him and control him that could never take away from how much she knew that she couldn’t control herself. Touching his thick manly neck, all she could think about was how thick his penis had been in her grasp.
His touches on her pubic region became more aggressive. His big middle finger was slipping in between her pussy lips while still fondling her sensitive area. Her pussy wasn’t naked yet but her clit was slipping out of the nub and twitching like crazy, that’s how much she wanted it. He hadn’t moved his hand one bit, he was still fondling her down there, but he began making an effort to pull off the undergarment just with the force of his hand alone.
That wouldn’t do. She pushed him back with a burst of strength that surprised even him. He looked up at her, not sure what to do. But grabbing back onto his penis, Kendra climbed back on top of him and sighed happily feeling his naked cock that close to her vagina, barely protected by her soaking wet panties. Hold the base of his massive shaft, she slowly lowered herself down on him and inside of her. His penis pushed up into the folds of her clothing and then he was directly inside her.
“Oh fuck...” she whimpered.
“That good for you too?” he gasped.
“Yes. Please just...”
She didn’t complete that sentence. Not when she started riding him. She was still wearing her panties, but she acutely felt him inside of her pussy like she was naked. The only thing Kendra could do was grunt.
Both of them were sitting still for awhile. His cock had wholly filled up her crevice beyond what she could imagine and it was both unbearable to sit on but also felt really damn good too, while he couldn’t believe how tight she was. Even with his dick not being inside of her naked vagina, the intensity of her cunt was like she really was naked. At the same time, the texture of her soft panties enclosing on his fat dick, her wetness seeping through the fabric and coating his pecker, in a way it really was better than the moist folds of her twat straight on his penis.
The pressure got so intense that he was the first to move up inside of her. Kendra had no choice but to grab onto his shoulders and clasp him tightly, gritting her teeth from the almost violent sensation of friction and pleasure. Squirming on top of him, she made an effort to move back with him.
It was almost like watching two virgins fuck. They were both so horny and clumsy that they were just grinding up on each other, not really properly doing it together. While they were still trying to find a groove to it, he regained some semblance of power first and reached up her torso, feeling her body enclosed in her shirt underneath her jacket. He could feel her shapely torso underneath, outer impressions in her EarthGov uniform made her look if not plain, then too professional to be really getting a raging hard on for like he had now. But now that he was getting a real hands on approach, she was every bit the nubile vixen he wanted.
He was kissing her neck. His lips that close to her ear. “Am I better than your girlfriend,” he said in a heated gasp.
“What...?” she said, unsure if she heard him right.
“You said you had a girlfriend back home and...”
That’s right, she had. But Kendra’s mind was so flared up that she couldn’t be sure anymore if she really did have a girlfriend, or if it was just part of her cover story that she used to deceive everyone else on this mission. She couldn’t even be sure if it wasn’t anything other than a Marker induced hallucination. She only made a single lustful sigh in response to his inquiry.
Not that she could even begin to ponder such a thing. Not with the penis rocking her insides, not with the way he was eating her ear, and not with his hands moving up under her shirt and feeling the bare skin of her torso. Wanting to get naked, Kendra clumsily began moving on getting her jacket off.
While she was doing that, his hands were on her naked back and had found her bra. He worked on getting the clasps undone at the same time she was making an effort to get her arms out of the sleeves of her jacket. As he was doing it, she had deliberately moved her face down on his and then they were making out again.
Kendra moved her arms up and finally tossed the jacket aside in a very rough and crude motion. She was just as determined to get her shirt off and reached down under the hem and raised it up over her body and threw it away. Now with her torso all but naked before him, he moved back to look at her.
Despite her professional and no nonsense demeanor, she really was fine. Big tits, flat stomach, no real blemishes on her skin, her baggy work uniform didn’t do her any justice. Her bra was lazily hanging onto her chest, and the only part of her boobs that were covered from his greedy eyes were her nipples. Grinning to himself, he tore the rest of her bra down with his teeth so that it would have fallen right off if not for the straps still on her shoulders.
Kendra’s legs wound up around his waist and she held onto his neck. She looked right at him and nodded at him vigorously. He knew what she wanted without her saying a word and rubbed his face in her titties like a dog sensing the needs of a bitch in heat. They were so pliant and full, her big pliant flesh easily moving on his face like jelly, he couldn’t contain himself.
He didn’t do that for too long. His face in a pair of big naked honkers, he began sucking all over them. He would take each of them into his mouth and sloppily inhale it only to move onto the next one. Kendra held onto the back of his head, spurring him onto it while gripping her fingers deep into his hair.
They were moving on each other hard now. No sign of hesitation between them, they were fucking each other up real good. She had started riding him hard first, the way he was sucking her tits was making the aching inside her cunt so much worse, and then he was driving his dick right back inside her. If you tried to convince anyone about the dangers of the Marker by showing them this lewd scene that popped up out of nowhere, Unitologists would just try and save face by marketing their gospel as a solution to marital troubles. Make us whole indeed.
Kendra gasped when she was suddenly driven to an orgasm. He momentarily stopped too from the force of her folds clenching tight and milking at his dick, that’s how intense her climax was on him. But he was very nearly about to blow.
Kendra felt it too. She began humping him harder than ever in the chair, she wanted to drive him to satisfaction. Only that she rode him so hard that she actually fell down on the floor.
The deprivation of her pussy on his dick was like being denied water in the desert. He looked down at her, she was on all fours with her ass sticking up in the air. She was still panting, moaning, and then she looked back at him. She moved her hands all over the back of her luscious thighs, on her asscheeks sticking out of her panties, then she actually slapped one of those asscheeks. He instantly stood up and rushed at her.
While he was getting at her, she pulled down her panties for him, exposing her bare mound and jammed one of her fingers into her vagina, tempting him. As soon as he was near her, she took her finger out and wiggled her bum right in front of him for his viewing pleasure. He wasted no time in getting his prick right back in there.
