Chapter 1: Warm Enough?

Chapter Text

You’ve counted fourty one days since the spaceship transporting you and thirty four other passengers was hit by an undocumented asteroid and crash landed on an unknown planet. You and Commander Mills, the sole survivors of the crash, have been on a gruelling trek in search of the other half of the ship that contains an escape pod, which is your only hope of getting out of this place.

Running low on supplies, the lack of sleep and trying not to get eaten by some blood thirsty animal has started getting to you. You are grateful for Commander Mills however; if it weren’t for him, you don’t think you would’ve even made it this far. You’re even more grateful to him when he cheerfully calls your name while you rest against a tree. You follow his voice as you reach a clearing in the trees and see him standing near the edge of a cliff. You walk over and stop beside him. He holds a computer in front of him, pointing it at a mountaintop at the other side of the valley.

“Escape vessel located fifty kilometers ahead.” You hear a robotic female voice say.

“You found it!” You blissfully shriek, jumping with glee on the spot. He places his free hand around your waist, squeezing gently, as you wrap both of yours around his neck. Your face is inches from the crook of his neck and you breathe in his earthy scent.

“We’re going home.” He says softly in a bundle of your long hair, his palm now caressing your lower back in short, comforting movements.

As the sun begins to set, you mutually agree to rest for the night and continue your journey again at sunrise. You set up camp on a smooth patch of ground, then take the initiative to re-fill your shared water bottle at a nearby stream.

You walk onto a rock over the water, squatting down to reach it. You begin to wash your hands first, noting how cold the water feels against your skin, making you shiver. You grab the bottle next to you, open the lid and lower it down to fill it up. Without warning, one of your feet slips on some slimy algae, thrusting you straight into the freezing cold water as you yelp in surprise.

The unexpected impact and difference in temperature makes you hiss in pain, but as your head submerges under, you end up choking on water. In a panicked and disoriented state, you try your best to flail your arms to bring you back up to the surface. Your head resurfaces quickly then and you desperately gasp for air. You cough uncontrollably as your body tries to get rid of all the liquid you just swallowed.

“Take my hand!” You hear Mills’ gravelly voice shout as he extends a strong arm towards you. You swim closer to the edge and the moment you grasp onto him, he swiftly pulls you out. You continue to cough and he proceeds to rub your back to help soothe you.

“Are you alright?” He breathlessly asks. You nod as you focus on getting your breathing back to a steady pace. If you didn’t know any better, you might have believed he was genuinely worried about your wellbeing; despite only knowing you for a month and a half.

He notices you’re shivering before you do and he guides you towards the campfire that he lit up whilst you almost drowned yourself.

You sit in front of the fire and hug yourself tightly to try to warm up but the chills don’t seem to give up.

“You need to take your clothes off. They’re not doing you any good when they’re completely soaked.” Mills advises -or more like orders- you, standing with his arms on his hips next to you. You know he’s right, so you obey and begin to strip. He turns around to give you some privacy, creating a makeshift clothing rack with rope in the meantime.

“I’m done.” You let him know once every piece of clothing is off your body, standing behind him with your arms crossed over your breasts.

He turns his head halfway to look at you, forgetting for a split second that you have no clothes to change into. His head snaps away from you when he realises but not before he takes in the smooth contour of your breasts. He slips his oversized zip up hoodie off his shoulders and proceeds to throw it back towards you as he mumbles an apology. You notice him tense up at the uncomfortableness of the situation but even though you’re the one who’s naked, you’re not the least bit uncomfortable with the idea of him looking at you. In fact, part of you craves just that.

You thank him as you slide your hands through each sleeve and zip it up. The hoodie sits just above your knees but you welcome the warmth on your upper body. Once you sit back in front of the fire and give him the all clear, he turns around to pick up your wet clothes off the ground. You offer to do it yourself but he insists. He’s almost finished placing each item on the clothing line until his large hand grabs onto your wet undies. You’re too busy warming yourself up to notice how he holds them for a second longer than any of your other garments, his breath getting caught in his throat.

With the sunshine gone and the temperature dropping for the night, the shivering intensifies. You rub your hands together, rocking back and forth in an attempt to warm yourself up. Your jaw trembles, making your teeth chatter loudly.

Arms wrap around you from behind and Mills’ chest comes into contact with your back. His legs slide on either side of yours, as if attempting to create a protective cocoon around your body. His hands hastily rub your arms to create heat.

You close your eyes as your body begins to warm up and relax. You can feel Mills’ warm breath on your neck and you instinctively lean back into him. A moan escapes your lips as the feeling in your body comes back, bringing with it an unexpected feeling between your thighs. You pray that he didn’t hear what just came out of your mouth, but you’re no fool; It’s the middle of the night in a forest. There are no other sounds apart from the faint chirping of crickets. Of course he heard it.

His muscly legs squeeze against your own as he continues to rub your arms. You swear you can feel a hard bulge on your lower back, but you don’t know if it’s actually true or wishful thinking. The thought sends a different kind of shiver down your body and then it becomes too hot. There’s heat radiating from his body that’s spreading to every part of your own.

You feel something wet and slick between your legs and you know it’s no longer the river’s fault. Moments ago all you wanted was to be bundled up in every bit of material you could find and now all you can think about is ripping the damn hoodie off.

“Too hot.” You mumble and disconnect yourself from him, sliding forward slightly. He feels as hot as lava. Your instinct is to get away and yet you crave his scorching touch. The thought makes your head spin.

“Are you okay?” He asks, a concerned tone attached to his voice. He places a light hand on your upper arm and you instinctively turn to face him with your entire body as you lean on your knees.

“Too hot.” Your repeat once more. It’s all you can say as your brain turns into mush at the sight of him.

He places a hand on your forehead, furrowing his eyebrows. “Shit. Do you have a temperature?” He asks out loud, more to himself than you, as he checks the warmth of your skin.

“It’s not that.” You say, grabbing his hand from your forehead. Your grip on his wrist remains as you lower both of your hands to the ground. “It’s this.” You admit, and press his fingers against your wet core.

His completely serious and worried expression turns dark in an instant; Like a shark that’s spotted its next prey, ready to devour it whole. He begins a long stroke between your labia with his thick, middle finger, from your throbbing hole to your needy nub. It feels like forever since the last time you were touched.

You slowly grind against him, pushing into his finger as your thirst for him becomes stronger. He forcefully grabs you then, turning you so that your back is once again flush against his chest. His grip is painfully tight on both of your shoulders, as he tries to stop himself from doing something he’ll regret. Ever since he landed on this unpredictable planet, it’s like the dial for his primordial instincts has been turned to the highest setting. He’s tried his best to hold it together but now that you’re practically giving yourself to him, all he wants is to destroy you and mold you back together again and again.

“I don’t want to hurt you.” He confesses, a hot gust of air hitting you behind your ear. It should scare you, but it only drives your desire for him further.

“I don’t mind if you do.” You admit. It’s like you’ve been possessed. You’ve never wanted something this much in your entire life. It’s like running low on oxygen and the only way to get it is from him.

“I have a wife.” He attempts to reason with you through gritted teeth. You can tell by how tense his body feels, how hard he’s trying to keep it together but rather than deter you, it only spurs you on. You’ve never been one for wild sex or adultery but in this moment, you don’t care about anything else but him. For all you know, you may never make it back home. Might as well enjoy it while you can.

You turn your head sideways to up look at him and grind your ass against the tightening bulge in his pants. He looks pissed and it only makes him hotter. You grind a little harder and that does it. He grabs the back of your head, aggresively colliding your lips together in a heated kiss. He forces your mouth open, slipping his tongue inside and you moan in pleasure. His hand slips down your body, his fingers touching your heat without warning. It makes you jump, causing the tip of his finger to slip through your entrance. You yelp in surprise and move your arm over and behind your head to slide your fingers through his hair. You tug him closer as your lips continue to fight for dominance.

He seems to enjoy the aggresive tug on his hair as he grunts and pushes two fingers inside your dripping cunt. You whimper at the sensation and move your hips up and down in a steady but needy rhythm. His free hand moves to the zipper of your hoodie, unzipping it halfway to expose your breasts. The fabric slips down your shoulder and his large hand cups your plump tit.

Your mouth opens against his, as you become completely immersed in the pleasant sensations he’s giving you. He places his palm harder against your clit and speeds up the pumping of his fingers. Your pussy clenches all around him and you squirt all over the both of you as your organsm hits without warning, “Fuck, Mills!”

Without giving you a moment to recover, he pushes you forward. Your hands instinctively reach out in front of you to stop you falling on your face but the impact causes the gravel to scrape your palms. The pain however, is muted by the burst of serotonin that’s being released in your system.

You hear a clank of a belt and a zipper, then he’s thrusting into you, his cock splitting you open. You grab a handful of dirt to steady yourself as it’s the only thing within your reach. A deep, hungry groan escapes his lips, making your pussy clench harder against his member. Your vision is constricted by the hair that’s fallen on either side of your face. Your wet strands swish back and forth in sync with his thrusts.

“Lean against that tree.” He commands with his deep, raspy voice. You crawl on all fours to the tree beside you, your legs trembling and grab onto the trunk in an attempt to steady yourself. His warm lips connect with your exposed shoulder, spreading sloppy, wet kisses all over your skin. Both of his hands firmly squeeze your exposed breasts before trailing down and connecting to your swollen clit. You’re already on the verge of another orgasm but you miss the full feeling of Mills’ girth inside of you.

“Please Mills. Fill me up. Please.” You beg, not caring to hide the desperation in your voice.

“Sit on my cock, baby. Fill yourself up until you can’t anymore. C'mon.” He urges you as one hand rubs your clit and the other squeezes your ass. You begin to sit back on his lap, as your pussy devours every inch of his length. You stop when you think you’re completely full of him but to your surprise, he grabs your thigh, pushing the last remaining inches inside of you. You whimper as you feel the tip of his cock hit your cervix. It’s almost too much to bear.

The pressure of his fingers on your sensitive button encourage you to carry on, slowly coming up and then back down on his cock. Before your know it, you’re practically jumping on his lap as he disappears in and out of your stretched cunt.

Mills lets out a dirty, hushed whine and your ego inflates by the obvious effect you’re having on him. Your hand reaches underneath you, grabbing and squeezing his balls. Another whine escapes his lips, this time, even louder.

His free arm extends towards your neck, his fingers squeezing firmly against it as your back collides with his chest, removing any space between your bodies. Your hands wrap around his forearm and your eyes close at the mixture of pleasure and air constriction. He quickly takes over, thrusting in and out of you desperately while he rubs circles around your bundle of nerves.

You feel yourself cumming for a second time as you let out an unrestrained cry. His pace doesn’t give up until you’re squirming at the overstimulation and he pulls out at the last minute just as thick strips of cum shoot out of him and onto your bare ass.

You zone out for a while, only coming back to reality when you feel a cloth between your legs as Mills cleans you up.

“Turn around.” You obey his order and turn to face him, feeling unexpectedly shy. You watch as he reaches for your hands and turns them over so that your palms are facing up. He grabs a clean piece of wet cloth and begins to dab your wounds clean. The gentleness of his touch is a complete contrast to the way he was fucking you a few seconds ago.

Once he’s done, he guides you to the wooden den he made out of sticks and branches, and you both lay down. His arms wrap around you once more, but there’s no roughness this time.

“Warm enough?” He asks, a hint of a smile in his tone.

You nod before dozing off to the best night’s sleep you’ve had in a long time.
