The sound made by the hydraulics of a standard maintenance hatch as it split into two halves and opened should have been something so common to him that it passed without notice. Jack had been on Gagarin 1 for such an extended period of time that the unique sound was as commonplace to him as birdsong to those who lived planetside. But then the sound was not usually accompanied by so much anticipation or the same fear of discovery as it was on that particular night.
Jack turned from the small dome of the observation blister with the skill and precision only known to those who had spent long months living in a zero gravity environment. He controlled his motion without a conscious thought, much the same way that one would walk without any concentrated effort when under the influence of gravity, spinning his body so that he could see down the length of the service tunnel behind him.
The shapelessness of his blue jumpsuit could not hide the fact that he possessed the slender and somewhat spare physique that had become the stereotypical image of the career space worker back on the surface. Though he was only average in height, the lack of gravity and the constant regime of exercise required to keep his body from withering to nothing meant that Jack seemed taller and more elongated than he was in reality.
Part of the impression was based on the all too real effect that the weightless environment had in allowing the spine to stretch to its full length, adding perhaps half an inch to the average height. But the largest part was down to the way in which his limbs, devoid of anything but wiry muscle and sinew, had learned to move with an almost balletic grace in response to the effects of his new surroundings.
Unlike many other space workers, Jack kept his hair long enough to reach his shoulders and pulled the dirty blonde tresses out of his eyes with a broad elasticated band that left it trailing behind his head like a golden halo. His eyes intense blue eyes added to the image of a somewhat unruly and rebellious young man, darting about as they did now inside deeply sunk sockets with an air of nervous anticipation.
"Olivia," he called into the shadows of the tunnel, "that you?"
"So long as you're Jack," the answer to his question came in a voice that was obviously both female and suffering from a certain degree of the same nerves infecting him at that moment in time.
The familiar tones had an instant effect on his mood, chasing away some of the anxiety that had seized him whilst he had been waiting in a matter of a few seconds. Also, with some of the pressure lifted, Jack found that he was able to put on some of the confident demeanour that he was sure the situation in which he now found himself would require.
"Glad you could make it," Jack managed to purge most of the trepidation from his voice as he spoke. "Hope you didn't have too much trouble finding the place." He was too focussed on the here and now to realise that he sounded like an accountant hosting a house party for the benefit of his clients.
"Your directions weren't that bad!"
Olivia's response failed to properly register as she emerged from the mouth of the tunnel and into the six foot square junction beneath the blister. Though Jack had known her for more than a decade and he had learned to hide it very well in that time, there was still a moment or two when he was caught off guard by the sight of her face. There were women whose faces looked better on paper for any number of reasons, but it was simply something about Olivia's face that slipped past his guard and made his pulse quicken.
It had always been the same way for him, ever since the day they had met back in high school. Her bright and open smile seemed able to affect him in a way that no other woman had ever been able to. It added a light to her elfin oriental features that brought her to life in a way which seemed to be absent when she wore any other expression.
She wore a jumpsuit that was superficially similar to his own, but on off white colour indicating her status as a member of the orbital platforms medical staff as opposed to his own position as a technician. Her sleek, black hair was still bound up in the practical braid that she wore during her duty shifts, reaching down almost to the small of her back and keeping her large brown eyes clear while she worked.
As she emerged from the shadows and into the light that the blister allowed into the junction, her pale skin was illuminated for the first time and Jack found his eyes drawn down towards her neck as if by an irresistible force. He saw that her jumpsuit was unzipped to the waist and the garment that she wore beneath was a mesmerising combination of black material and light reflecting on the curves of her body.
Jack had always tried to be a thoroughly modern man as far as Olivia's other striking physical features were concerned. It was strictly Neanderthal to resort to the same kind of attitudes that had been common amongst men in the past centuries when it came to the opposite sex. But there was no escaping the fact that she did possess exceptionally large breasts.
And there they were, staring him in the face from beneath a layer of spandex that made them all the more noticeable against the drab colour of her jumpsuit.
Back on Earth they had been something that it had taken a great deal of practice not to simply stare at in admiration and awe. But in zero gravity conditions they seemed to have been granted a life of their own. Liberated from the downwards pull on their mass they floated freely and had caused more than a few collisions between colleagues who should have been looking where they were going rather than at her chest.
Olivia looked around the junction and then gave Jack a conspiratorial grin. She was a shy and retiring girl by nature, but he could see in her eyes that she was pleased with the reaction her unzipped jumpsuit had caused in him. He had to admit that he had no idea how much courage she must have summoned to behave even meet him there in the middle of the night, let alone dressed in such a provocative manner as well.
"You're sure that we're okay here?"
"Of course," Jack tried to calm her nerves. "I work this area of the tunnels on most days and I know who's where at most times. We're always pulling an extra shift for each other on my team, so convincing them to let me cover a few hours here and there in return for having this place to myself for the night isn't really a big deal. And before you ask, no one knows why I want to be alone up here tonight and they're not the kind of guys who'd even ask."
That seemed to reassure her somewhat as she drifted closer to him and he deftly twisted to meet her, placing a gentle hand on her wrist to that they turned slowly with the effect of each other's momentum.
"I brought something," Olivia proffered a small styrene container with a pair of robust drinking straws inserted into a circle of foil on the lid, the standard method of preventing random incidents of inconvenient beverage escape on the orbital platform. "It's champagne," she laughed nervously, "seeing as how we're celebrating...sorry about the box, but it was all I could get at such short notice."
"No," he shook his head, "it's fine."
He couldn't help laughing himself.
"Champagne from a carton," Jack shook his head. "This is going to sound awful, but it kinda reminds me of you."
"What?" Olivia filled her voice with mock-horror.
"I mean something really special in an ordinary package."
"I suppose I should find that flattering?"
"Ah," Jack rubbed the back of his head, "don't be mean to me; the nerves always get to me at times like this."
"I know what you mean," Olivia took a sip of champagne from the straw and offered the carton to him.
At the time they had made the pact, it had seemed like nothing more than a casual notion, tossed out in a moment of abandon. But now the time had come for them both to be good to their word, it seemed that the nerves were getting to both of them.
Though it was becoming ever more common for people to work on the orbital platforms now that they were so many in number, it was still a rare occasion when two individuals who were known to one another planetside found themselves in close proximity when they did so. When Jack had recognised Olivia's name on the roster of new staff coming aboard on the standard three month rotation, the first thing he recalled was the pact and the amount of time that would elapse before they would be confronted with the prospect of fulfilling the promise they had made to one another back on Earth.
In truth it was a natural thing for human beings to want the bragging rights that came along with what had become known as getting one's space wings. With the advent of commercial flight more than a century before there had been the compulsion for the same kind of people to join the mile high club with a cramped and frantic liaison in a bathroom cubicle. Of course the kudos of being able to claim that one had partaken of sex in space was now the focus of the same attentions and secretive meetings in hidden locations.
