Humans lived longer, travelled more, and enjoyed relatively good health. On the down side, fertility rates were down, with more people unable to have children or having bad timing, as well as a diverse number of genetic and environmental factors that contributed negatively to fertility and conception.

Finally the Biological Imperitive had been put into place, it was a simple thing, a body sensor that alerted women to their own fertility as well as the availability of a suitable partner. Only fertile humans had sensors, and it had become a burden and a sign of prestige.

There was one other component, when a woman was at peak fertility and a highly compatible male was nearby both sensors released increased hormones into both humans. It was meant to drive them together and most of the time it worked.

Right now Makla wished she didn't have to wear the damn thing. The silver band glowed around her left wrist, flashing and beeping. She was alone on her ship and the thing must be malfunctioning she thought, as the hormones surged through her body. She did the only thing she could think of, she set her ship to autopilot to take her to the nearest available planet or port. The damn thing would keep flooding her system with desire for three days or until she had sex with the person whose sensor was also going off. She was hoping to find someone or something to make those three days tolerable as she headed for her sleeping quarters nearly ripping off her space suit as the fabric was frustrating rough on her suddenly engorged nipples.

Makla slumped into her bunk and began masterbating, the ship letting her know she'd reach a destination in a few hours. She growled her frustration and opened up the shower, hoping the water and sonic pulses would ease the sexual tension in her body.
 
(Hope this is ok)

A dying uncle had left Dev the deed for "Cisco Alpha", a unique trading space station. Dev assumed that it would be his ticket to getting rich, only to find that the station was in the middle of no where, a few hundred clicks from the trading lanes, and that the only ships he got were ones who broke down, or a ship where a munity had occurred, and the rebellious crew was looking to dump the commander.

He was sitting, slumped back in the chair on the command deck, watching the long range sensors. Occasionally, a ship would come near, but would rarely dock. He could barely afford the cost of supplies to keep him alive on here.

He sighed, and moved back to a data pad that contained last month's news update, which has usual, moaned on and on about the Biological Imperative. He got angry and threw the pad down on the steel floor. Most of all, he found it hard to live without any female contact, and even jerking himself barely provided a rise of excitement.
 
The warning beckons went off and she found time to throw on a robe, her body was on high alert. Right now she'd be happy with a drone, slang for an infertile male, or heck even a human compatible species. She managed to nail the landing despite the intense sexual need coursing through her body. All she noticed was that there was a human on board. Whoever it was, they would service her, no human would be so cruel as to ignore the way her sensor was going off like an old Vegas slot machine. She ran to the hatch and hurled herself off the ship, gravity was pretty low as the price to maintain Earth standard gravity was costly. She wondered where in the hell the human was and why he or she hadn't greeted her by now. Makla took a deep cleansing breath, taking a moment to consider their point of view. It would be a shock to find a pilot alone in such a state with her sensor flashing and glowing. She straightened her robe, the pale cyan silk clinging to her damp skin, the lower edge barely hitting mid thigh. She hadn't bought the garment expecting anyone to ever see her in it. Right now she would have screwed the most loathsome human, the thought disgusted her slightly and she hoped whoever was available would be pleasant about her plight.
 
Dev carefully navigated the dark metallic corridors of the station until he arrived at the airdock.

A woman was standing there, wearing one of those silly body sensors, which was flashing and making all sorts of noise. She was wet, like she had just climbed out a shower. Dev cocked his head and stared at her for a moment. She was wearing a small, revealing robe.

He wasn't sure what to say, "Can I help you, ma'am?" he asked, although he could feel his manhood inside his pants start to become long and stiff at the sight of the pilot in heat.
 
She wasn't sure whether to be relieved or pissed that he didn't have a sensor, well drone or no, in a remote station like this she doubted he got much action. She almost spat out a sarcastic comment that wasn't it obvious? Then again he might not have a sensor because of his location. She managed a smile, "Yeah I really could use a fast fuck, please tell me you are capable." She didn't even want to think of the fact that he could be a drone without the capability of an erection, at this point it didn't matter, she'd use his hands or mouth just as easily.

She waved at her body sensor, "Damn malfunction has me hot enough to fuck anything."
 
Dev felt his growing cock fighting against the fabric of his jumpsuit pants, at her comments. He let out a slow, long breath, and wondered if he was dreaming. His eyes traveled up and down her body and he paused a moment before speaking. "I guess... " he studdered and paused, not sure what to think or do, "I, um... I can... I'm capable of... Fucking, you know," he said, trailing off.

"I mean, I haven't had anybody come and talk to me about the Imperative. I don't know anything about making babies or whatever those things are for," he explained.
 
She wondered how old he was that he hadn't been tested yet, then again if he was out here the government might have decided it wasn't worth cost of transporting him to a reproduction center, test him, and outfit him with a sensor, and transporting him back. "Well if it was working correctly this would mean I'm not only ovulating, but that a genetically ideal male is nearby. It's been pumping me full of hormones to make the mating process a need rather than an option." She paused, her robe was driving her mad as it caressed her engorged tits with every word. "I'd love to go over all the details but I really need to fuck you." She dropped the robe revealing her extremely aroused body. "Sex should get the alarms to stop, but I'm going to be extremely fucking horny for the next three days, so I hope it's not too much of a hassle for you to service my sexual needs until then."

She stepped towards him, her full hips swaying as she moved, her full breasts plump and luscious looking in the low gravity, the dark pink nipples swollen to a near painful size.
 
Although he was confused by the whole Imperative, he did understand one thing, and that was this horny woman was standing naked before him. He moved before her, and brought both of his hands to her ample breasts, his palms carefully taking in all of them while his fingers roamed over her hard nipples. He pressed his lips against hers passionately, and felt his cock now practically breaking free in his pant.

He moved his mouth down, his warm lips wrapped around her hard peaks and his tongue began playfully lapping over her sensitive nipples. His left hand, its place on her breast taken by his mouth, moved to her flat toned stomach where it sensually grazed her damp skin.
 
Her body relaxed at the physical contact, and the room started spinning. The kiss was a little unexpected, but very nice, she kissed him back with all the built up frustration of several hours on the edge. Makla pressed against his touch, realizing that while she was revved and ready to go, he probably needed some time to get to the same point. Her hands tugged at his pants, wanting full body contact as soon as possible.

The feel of his hot mouth wandering down to her breast was a relief of sensations, one hand running through the hair on his head. Her legs spread shoulder width apart, her swollen wet cunt aching for more.

He was going a little too slowly and she growled uncharacteristically and pulled away long enough to yank his pants down to reveal his was definetly capable. The low gravity encouraged blood flow and growth, typically adding to length and girth in space. It was well known that all porn was made in low grav for that very reason.
 
Dev was almost excited himself by the size of his own manhood. Of course, it was bigger in low-gravity, but it was bigger than he had ever seen it, even the random times he pleasured himself. It supposed it must be this woman and her strange needs were having some sort of effect on him.

He gestured towards a nearby work bench near the airlock where a damaged space suit was waiting. He moved there and pushed the suit onto the floor, and stripped off his shirt. He started stroking his own manhood and pointed to the bare workbench. "Get yourself up on here and we'll get down to business," he said to the nude woman, himself feeling a bit more confidant with the situation.
 
She had thought she was going to have to take charge of the situation, which woulnd't be much of a problem except her body was aching for it. She watched his cock swell to full size and she sauntered over to bench, she wanted to get bent over and taken like an animal but the bench wasn't ideal for that so she sat down straddling the bench leaving a wet spot between her legs. She stretched out and idly stroked her slick cunt in preparation.
 
Dev moved closer to the bench and placed one hand on her waist while his other hand grabbed the head of his cock and guided it near her soaking pussy. Slowly, his manhood penetrated her. He slowly extended his cock inside of her until he could no longer. He let out a low moan at the fantastic feeling of her warmth around him.

Soon, he braced his hands on her hips, and began pulling his cock in and out of her with his hips only. He started slow, forceful and deliberate at first, but began picking up speed. He felt the heat from the friction speed up on the muscular sides of his dick while he starting thrusting faster, and harder. He let a low guttural moan escape from his lips.
 
She struggled to not move her hips, but his hand upon her helped, and she allowed him to dictate the pace as it the alarms had stopped sounding and the lights were no longer flashing. In fact even the lights seemed to dim as her bodies natural response was being recognized. She'd had her sensor light up almost every month, but being in space aging slowed down such that it hadn't gone off in quite a while. Then rational thought was banished as their bodies merged in a rhythm older than time.
 
Dev moaned and started thrusting harder and harder. He didn't even know this woman's name, yet he was here, fucking her. One of his hands reached up and fondled her ample breasts, and his fingers carefully grouped her hard nipples. He felt could feel the excitement, and he felt better than he had in months. She felt wonderful, almost like a dream.

He hadn't fucked in years, and knew his stamina would be effected. True enough, he could feel a familiar pushing feeling in his balls and new he was cumming close. He started to slam his cock harder and faster inside of the stranger, hoping to get as much fucking in as he could. He pinched at her tits and let out a passionate scream before ramming his cock in as far as he could, and realized his warm seed inside of her.
 
She'd been on edge so long that it seemed strange to finally cum, her body exploding as she felt his cock explode inside her. Her insides melted around him in the extasy, her sensor finally dimming and the world coming back into focus. Her hips nudged up against him, wanting to eke out a few last moments of pleasure as the last ripples of warmth faded from her body.
 
Dev kept his cock inside of the mysterious beauty has long as he could before it became too limp, and he slipped it out. He bent over, and gave the woman a long, passionate kiss while his hand fondled one of her breasts.

He stood up and admired her body. "My name's Dev. What's yours?" he asked with a grin.
 
"Makla," she said with a soft purring tone. "I should be good for a while, perhaps we could move to more comfortable surroundings?" despite having the fuck she needed her nipples were still proudly erect, her cunt tingling from the pounding, juices still flowing. She could have fucked immediately but noticed his cock was going to need some down time.

She slowly stood, "Thanks by the way. I really needed that, and it'll be a lot easier from now on."
 
"Dev, no problem, miss," he said, reaching for his disgarded closes from the floor. "There is my quarters, above the command deck. It isn't much, but there is a bed and an actual bath tub, not just a sonic shower," Dev said, bragging slightly.

"Where are you headed?" he asked, handing the woman her robe.
 
"I've got a pick up on Krantor, but I booked it to get here, and it's not time sensitive, so after I leave I'll just send a message saying I had some trouble and got delayed." She left her robe by her ship, she saw no need in dressing as her body was pretty much on constant readiness and other than a few hours of sleep here and there she wanted to be ready to fuck him at any time.

"I'm pretty lucky you're out here. It's a pretty deserted place for a trade station."
 
"Heh," Dev commented while he lead Makla through the narrow steel corridors of the station. "Tell me about it. I can go months without seeing a single ship," he said while the pair navigated up a narrow staircase.

They arrived at the top, and Dev entered a simple security code into a keypad to admit them into the quarters which were located on the very top of the station.

They were fairly large, yet mostly unfurnished, with a simple bed, and a rather ugly, yet well equipped bathroom. It was also messy, Dev's dirty clothes were scattered about, and a few large crates of supplies were also located in the room. Two large bay windows looking out at the star field were on the ceiling, however, providing a good view for those laying on the bed.

Dev turned to his guest, "So... that little thing on your wrist makes you... erm, horny?" he asked, still not quite sure why this beauty naked woman was so intent with fucking him every waking moment.
 
She stretched her arms over her head, "Yes and no, it's supposed to alert me to when I'm most fertile, and when the right person is available at the right time. When both occur it triggers a hormonal reaction, in order to make mating at the right moment more urgent." She laid down on the bed, "Typically the genetically compatible mate would be easy to find as his sensor would be going off, and mating would take place and calm the sensors. Since mine is obviously malfunctioning it just kept making me more horny, and will continue to do so for three days." Her fingers were casually stroking her body over her breasts and down to her now slightly sticky cunt.
 
He felt his limp cock stir and he approached the bed. He started stroking his manhood. "You're ready to go already?" He asked, slightly shocked.

He laid on the bed next to her, and reached over and fondled her breast slightly, he nipples were still hard and warm. "I guess I can go again," he said, watching his cock rise to its full length.
 
"I'm going to be basically constantly ready to go, but I am a lot more clear headed after we fucked." She bent one knee spreading her thighs, showing off her swollen slick cunt. "I hope you are pacing yourself, otherwise on the third day I'm going to be raping your mouth."
 
Dev chuckled nervously, although he was seriously afraid of the possibilities. He was far from being a virgin, after the armies of sleezy space port chicks he had banged, but he had never screwed such a dominant chick, specially one who had a suped up sex drive, and wanted to fuck for three days straight.

"Well, erm, I guess I could do one more quick fuck, if you want... for now anyway," he said, getting on his knees and positioning himself closer to her.
 
"Eager is good," she said with a big smile, "though speed is not essential this time," one hand was playing with one of her swollen tits, the other was casually thrumming her super engorged clit. She welcomed him between her thighs her wet fingers guiding his thick cock inside her hot body again.
