Nalirra was one of the third generation of the incredibly long lived People. Her tribe were the twenty specialists who ran the Ship, kept it maintained and liveable, and cared for the valuable cargo of non-gens, frozen original human specimens intended to build a new humanity when the ship completed its incomprehensibly lengthy voyage.

The People had been carefully designed for their task, engineered to provide the necessary expertise and skill, and to live happily in an environment that could be difficult, especially from a psychological viewpoint. Nalirra and all the rest of the tribe were human, but not to the original spec.

At first glance, most non-gens would have been struck by a couple of differences. Firstly, her entire body was devoid of external hair. Her head, eyebrows, armpits, and groin were missing the expected substantial growth, and the rest of her skin was without the fine covering that would normally be present. Secondly, this first difference would be very apparent because the People did not wear clothing. Ever. The constant temperature and humidity in the ship made both of these coverings unnecessary, and hair was a major maintenance issue in such a finely tuned long-term machine.

There was another physical difference which would become apparent if you looked for a moment. The People had tails. Long thin prehensile tools, equipped with the musculature necessary to allow them to lift themselves from the floor where necessary. The tail was equipped with a sensory organ on its tip, able to perceive fluctuations in light, heat and magnetic fields.

Glad to have completed her tasks for the day, Nalirra collapsed onto the bed, physically worn, mentally washed out, but definitely not sleepy.

Over the many years of the voyage, the People had developed an unwritten code for their social interactions. Part of this code dictated that beds in one part of the quarters nearest the engine of the ship, and arbitrarily named the South Nest, was set aside for those who wished to sleep quietly, and generally alone. The North Nest, a smaller area opposite was designated as a cosy social area. Not much sleeping happened there. At least not until very late.

Nalirra was in North Nest. She wasn't much in favour of sleeping alone, and a day of physical activity just meant she needed a little rest before the fun began. The people didn't use blankets either, a combination of the controlled environment, and superb engineering of the entire tribe, and she simply curled up on the soft platform, lying on her side with her tail behind her, along the line of her spine, and curled over her shoulder. The tip rested comfortably between her breasts. Within a minute she was sound asleep, and the next hour drifted by without her noticing.

Eventually, other members of the tribe drifted into the Nest, either before or after eating, depending on their priorities, and Nalirra woke as one of the men approached her.

Looking around, she saw there was a couple to her left, hetero, and with a flick of her head, another to the right. Nalirra liked to spend time with both men and women, but she mostly liked to go with the trend. The buzz was better. She beckoned to the man standing politely before her, realising now that it was Bortal, a good friend. Nalirra moved over on the platform, allowing him to lie easily in front of her, their bodies facing together, their faces near to one another.

"Nice nap Nalirra?"

"Not bad Bortal. You're not quite the worst way to wake."

"Just as well. I had another couple of offers, but you looked delicious lying there."

"Less talking Bortal. I need a kiss."

"You're not the only one. Looks like we need to catch up to Leesa and Garnout."

As they snuggled more closely together, their mouths met, and the embrace of their tongues cemented their willingness to merge their bodies more thoroughly.

After some time spent caressing one another's bodies, Nalirra tipped Bortal over onto his back, and lay down gently on top of him, her breasts pressing into his firmly mucled chest, her thighs avoiding his erection for the moment. Returning her mouth to his, they resumed the discussion their tongues were having.

The people weren't psychic, but they were something similar. An unexpected side effect of the engineering miracle that produced the tribe was an undocumented and unexplainable empathy for each other. In a sexual situation, this resulted in the ability to feel the excitement experienced by others nearby, and to pass on the arousal to partners and others. Frequently, groups of partners found themselves synchronising their movements and positions, thereby increasing the excitement felt. Orgasm was invariably a mutual, simultaneous thundersmack of release.

Looking around as best she could with her mouth attached to Bortal's, Nalirra could see her counterparts on the other two beds were also atop their partners, and also concentrating on oral communication without speaking.

As she reluctantly removed her mouth from that of her partner, Nalirra moved slowly down the bed, kissing his chin, neck, chest. On either side of her, the movements were repeated. Someone always took the lead in these group encounters, and Nalirra was frequently the instigator. Tonight she was definitely in charge.

Lifting herself from his body now, and seeing the girls either side repeating the movements almost in time with her, she felt as though a mirror had been placed on both sides of her bed. Crouching on her knees, either side of his waist, she could feel his erection between her legs, the tip touching the delicate skin on her inner thighs. Not feeling any need to delay, she lowered herself on it, his manhood easily entering the slippery tightness of her, the hairlessness of both of them adding to the tenderness and sensitivity for both of them. She could dimly feel the sensation from both his and the other minds. As she pushed him deeper inside her, she looked around to see the other girls similarly impaled. She felt hot and nearly ready, but she stopped moving for a brief time, to give Bortal a chanced to recover his equilibrium. She knew he was prone to overexcitement at this point, and she wanted to prolong this for a while. The other girls were similarly still, looking around and smiling as they waited.

Bortal was more than a little aware of what was happening and why, and as they all sat there suspended, he reached up with his hands and gently caressed Nalirra's breasts with the very tips of his fingers. As he, and his partners, slowly increased the pressure of the massage, he slowly moved his tail so the tip was just below her breasts. Allowing the tip of it to drift down over the silken skin, he directed it to her navel, caressing as only it could, and then lower still, until its softness reached her clitoris.

Knowing what was going to happen, Nalirra recommenced the movement on her lover's erection, lifting and lowering smoothly above him, the slippery friction arousing them both. In addition, his fingers continued their pressure on and around her nipples, and his tail started to tickle around her pleasure point.

The three couples were empathically linked more strongly now, and the bond was unbreakable. The girls were being caressed by an incredible sensual gestalt: erectile friction internally, fingertips on nipples, and tail bud on pleasure bud. Multiply this by the combined empathy of the group. The men weren't too badly off either. An ever accelerating pummelling from the love tunnels surrounding their manhoods, the feel now of the girl's hands scraping fingernails across their buttocks, and tail buds tickling their small but hard nipples.

As the speed of movement increased, the physical stimulation became less important than the mental link, and no one noticed when the tails were removed from their tickling places and twined around one another, strengthening the links within each partnership.

Nalirra knew she couldn't keep this up much longer, and as she glanced at the strained sweating faces around her, she realised again that she wasn't alone. Pushing down harder now, and squeezing him within here as best she could, she pushed all of them over the line, and as the three women pushed down one final time, all six participants exploded in orgasm, tails tensing tightly together, as did sexual organs, and a unified groan escaped from the group as all their muscles convulsed as one.

Slowly Nalirra collapsed on top of Bortal, he still deep inside her, their tails plaited together, their bodies hot and sweaty, and Nalirra kissed him deeply on his lips, and looking around again at the replication of their efforts, dropped off to sleep again, content until the next time.

Waking suddenly in the late darkness of the artificial night, Nalirra was aware of a change around her. The firm presence of Bortal was replaced by her favourite partner, Leena. She was softer, and a little smaller than Bortal, and of course was a woman.

Nalirra knew that Leena preferred a quiet private sort of lovemaking, and it seemed she was going to get her wish. The rest of the group was asleep around her, and Nalirra didn't want to wake them again if she could help it.

Leena was lying behind her, groin snuggled firmly to her butt, breasts pressing comfortingly at her back. Leena's lips were nibbling insistently at her neck, sending quiet pings of pleasure through her in the darkenss.

Content to receive pleasure for a while, Nalirra lay quite still, though Leena must have known she was awake. The caresses on her neck and shoulders continued, and Leena's groin was undulating gently against her buttocks now, an age old need for pressure causing the movement.

Eventually, Nalirra felt she needed to be more involved, and turned over to face her lover. Their mouths met as their arms entwined, and both girls explored all of the skin that was in reach. Groins pressed together insistently, damp and hot with the encouragement. As they both continued to kiss deeply, and their tongues explored the spaces available to them, Nalirra's tail slowly stroked down her partner's spine, and Leena took the hint and returned the gesture. The empathic loop turned this minor excursion into a major event, and they were both sighing on the bed as the tails reached the base of each other's spine, and caressed lightly down between the buttocks.

Comfortable and happy with her partner, Nalirra pushed her tail down further between Leena's legs, and between her willing thighs, and gently impaled her with the delicate tip of it. Leena returned the favour, and both girls moved their loins away slightly from her partner, and lifted a knee, to allow better access. The tail tips weren't able to spread and fill a woman like a man could, but the narrow soft tips tickled and awoke the inner nerves like opening a flower. Slowly sliding in and out of her partner, Nalirra could feel the same movements within her, and the stimulation was incredible.

The intrusions continued to be both welcome and pleasing, and both women were moving in time to the sliding tails now, buttocks sliding back and forth on the bed. Leena always liked some manual stimulation now, and Nalirra wasn't averse to a little assistance either, so she moved a hand down near Leena's hairless mound, and started to caress the slippery area as Leena did the same to her.

Soon their universe was a confusing mass of sexual arousal, and a drifting empathic link of pleasure. As both girls approached orgasm, the movement of their fingers and tails sped up, and the undulations of their bodies became uncontrolled. The mouths remained locked together, as much to reduce the noise as to provide pleasure, and they clamped their lips tightly as they came, shuddering to climax, clamping tails with tight muscles, willing fingers away from contact, screaming silently with pleasure.

As the throbbing slowed and sanity returned, Nalirra looked around and noticed for the first time that her neighbours had been woken, but they didn't mind obviously, as bodies were writhing in various stages of arousal all around. Leena disentangled herself from Nalirra's various embraces and turned over, and Nalirra cuddled up behind her, groin to butt, breasts to back, and slept again. This time until morning.
