The future… By 2625 AD, a large mining industry had been established on Titan, and with it came the three pleasure dome islands of Ecstasy, Elation, and Euphoria. These manmade islands were all constructed in the Kraken Mare Sea. However, by 2900 AD, robots did the mining, and the three pleasure dome islands were turned into adult-only tourist destinations available only to the lucky few who had won the daily solar system lottery.

Keith and Leanne are one of these lucky couples…

*****

“I can’t believe it!" Leanne exclaimed. "Just think. Fifty billion people are living in our solar system, and we were one of the three thousand lucky people to win a free ticket to Euphoria Island and its pleasure dome.”

“I know, Leanne, but we work hard, and I feel as though we deserve it,” Keith replied as he inwardly smiled to himself.

Unknown to his wife, their lucky win had cost him a small fortune, as he had purchased the winning ticket on the interstellar black market.

Keith joined his wife and looked out of the docking area’s large porthole window. Through it, they took in the distant Titan mountain range. It looked like it was floating on the teal-blue sea that surrounded Euphoria Island.

“However, Leanne, it is a pity we are only staying for one night. So we must make the most of our time here… Are you aware that Euphoria Island and its pleasure dome are places where couples go to have sex with new partners?”

Unseen, Leanne rolled her eyes before turning to face her husband.

She then stated, “Keith, I read the interplanetary web too. So, I do know that the pleasure dome is a place full of sin and vices. However, my understanding is that the rest of the island is much like any other adult-only space island resort, and maybe that's where we should spend our time.”

Her husband was surprised to learn that his wife seemed to know about Euphoria Island and its pleasure dome. He had been hoping that he could have seduced Leanne into visiting the pleasure dome, and couldn’t help looking disappointed.

Leanne picked up on her husband’s mood and decided to soften her stance.

"I do know you want to watch me having sex with another man, as you have mentioned it enough times when we were back on Earth.”

“Yes, but you always shut me down. I thought that here on Titan it would be different and that you might at least consider it.”

“Maybe it is different here… But I do need more time to think about it,” she replied, encouragingly.

Her husband smiled.

“Look, Keith, we can first explore the island. However, before you mention it, I do know the island’s pleasure dome offers all types of sexual services. And its atmosphere has a relaxing ingredient added to it, which helps reduce your inhibitions while at the same time increasing your sex drive.”

“Really!” Keith was trying his best to sound surprised. The laced atmosphere had been part of his thoughts in enticing his wife into stretching their sex life boundaries.

Leanne nudged him. She was fully aware of what her husband was thinking, and he knew the well-known fact about the pleasure dome's laced atmosphere.

“We are a long way from home and our family, around seven hundred and forty-six million miles from Earth.” Keith softly pointed out, hoping to prod his wife in the right direction.

Leanne smiled as she looked at her husband, his eyes now almost pleading. She stated, “But it is only seventy minutes by light drive… That is not so far!”

Feeling a little frustrated, Keith stood there looking at Leanne, his wife of twenty-five years. They were both forty-four, and to him, she still looked just as attractive as when they first met. Her long, shapely legs, dark, wavy hair, and curvaceous figure still had the power to seduce any man. Yet, with two adult sons living with them, they could not have the kinky sex they both sometimes craved.

As Keith took in Leanne's inherent beauty, his arousal reminded him of why he had taken her to Euphoria Island. Though it seemed unlikely now, Keith had hoped that this lucky one-night stay would spark a lustful sexual adventure.

With that thought still imprinted on his mind, he went up behind his wife and wrapped his arms around her body, drawing her into him so she would feel his hard cock.

“Someone’s pleased to see me,” Leanne chuckled, feeling his erection in between her shapely buttocks.

“Look, Leanne, while we’re here, you should remember that old Titan saying,” Keith whispered while nibbling his wife’s ear.

“The one that goes… ‘You have the most desirable wife on Titan?”

“Well, that one too,” Keith quietly chuckled. “But I was thinking more of the other one. The one that goes… 'What happens in Euphoria stays in Euphoria.”

Leanne turned and kissed her husband. “So, you are still having those naughty thoughts?”

Keith grinned, and he pointed to the welcome sign above the entry airlock. It read, “Euphoria Island, where fantasies can become realities.”

Leanne read it and then carefully stated, “Look, I am not saying something won’t happen here. But first, let’s get into the resort and enjoy looking around. Only then will I make my decision if we have a free pass for the rest of our stay here?”

It was at that moment that a mechanoid called them forward and read to them the island’s rules, one of which was that they were expected to wear the minimum of clothing. Their bodies were then scanned to check they were in good health. With that completed and passed, they signed all twenty-three health and safety waivers.  

Only then did they receive permission to enter Euphoria Island.

With their cases floating behind them, they jumped onto a transfer shuttle, which took the two of them under the welcome sign and through the airlock to their spacious living quarters. It was a room located on the outskirts of the island and offered views of the alien landscape and the night sky, dominated by Jupiter.

Once again Keith approached Leanne from behind and wrapped his arms around her. She turned and lovingly kissed him.

“Leanne, it feels romantic here,” he softly suggested, which brought a warm agreement from his wife.

“Let’s go and explore,” he then added, hoping that she would further relax and agree to the idea of going through the airlock and into the island’s pleasure dome.

Euphoria Island was split into three domed regions. The living quarters dome was where the guests slept and ate. Then there was the large tranquillity dome where you were encouraged to relax and let time wash over you.

However, it was the third dome that the island was famous for, the notorious pleasure dome. It was a place known throughout the solar system where you could go to indulge in illicit sexual activities, some barely legal.

Leanne knew that the pleasure dome was where her husband wanted to take her, but she was not quite ready for that. Instead, hand in hand, they strolled out of their sleeping quarters, both wearing only the lightest of white gowns, intending to explore the tranquillity dome.

There they walked along the shores of the indoor lake, its light blue, crystal clear water lapping over the fine yellow sand. The adult-only resort rules meant many of the customers took the opportunity to both swim and walk around in the nude, though neither Keith nor Leanne was quite ready for that just yet.

After a brief stop at a tranquillity dome bar, where the alcohol-fuelled drinks matched your taste and your mood, the married couple found themselves outside the entrance to the pleasure dome.  

“Come on, Leanne. While we are here, let’s go through the airlock and at least have a look at what the pleasure dome has to offer us,” her husband enthusiastically suggested.

“I don’t know, Keith. It is a big step to take in our marriage.”

“Leanne, we will only get this chance once, as it is unlikely we will win the daily solar system lottery ever again.”

His wife cast a sceptical glance at her husband and then turned her attention to the large white airlock door, which was currently guarded by a male mechanoid.

“Just a look,” Keith insisted and then gave his best cheesy smile.

Leanne somewhat reluctantly nodded and then stated. “But it will be me making the decisions, and do remember… Once we go through the airlock, we will be under the influence of the laced atmosphere, and it is unlikely we will want to go back… You have been warned!”

Keith’s only response was to grin in agreement.

The mechanoid scanned the couple with his cold, glassy eyes. Then let them through the airlock and into the darker pleasure dome. The heavy-scented atmosphere hit them as they stepped into a world of lust and vice.

To Keith, the air smelt of vanilla, while to Leanne, it was freshly cut grass. However, with every breath, the feeling of a deep euphoria swept through them. Their inhibitions, along with their long white gowns, fell away. However, not all of the guests were naked. Some people wore elaborate clothing that emphasised their sexual desires and preferences, while others were there to work and make sure each customer had a good time.

There were also the mechanoid men and women who had been carefully engineered to look like real, life-sized people. It was sometimes hard to make out if they were flesh and blood or just machines, the normal tell being to look into the eyes and see if there was any warmth there.

As they explored, it became apparent that the pleasure dome had a myriad of smaller domes inside of it, each housing its little secret world of desires, cravings, and sex.

Some domes housed sex shows, others orgies, or perverse sexual acts. However, when invited to join in, Leanne politely declined, telling her husband she would only consider doing something sexual if she thought it was unique, something that they couldn’t experience back on earth.

As they walked and watched, the intoxicating air they were breathing was making them feel increasingly relaxed and sexually aroused.

The horny couple turned the corridor corner and came to a new airlock. The digital sign outside announced that beyond was a weightless playroom with sessions lasting twenty minutes.

Leanne giggled, “This is the sort of place I was looking for. If we fuck in there, it would be different and fun. We would bounce around with others and have no control. Just think, Keith, there is a chance anyone could have me, and I am open to giving it a try – is this what you want?”

“You know my feelings, Leanne. Remember, we are only likely to get this chance once in our lifetime, but you are in control.”

Now totally relaxed, Leanne felt her husband’s hand gently caress her bottom, and seeing his cock was erect, she chuckled. “Keith, do you think you can last twenty minutes?”

Her husband chose not to respond. Instead, he walked straight in, leaving Leanne to follow in his wake. He was here to experiment, push the limits of their married sex life, and, above all, witness his wife having sex with another man… or even men.

Once through the airlock, they found themselves in a small chamber with a naked female mechanoid standing in front of another digital display. She welcomed them and spent five minutes explaining how the weightless playroom worked. They were told the atmosphere they were currently breathing contained a drug which would stop both weightlessness and motion sickness, as well as give the men a continuous erection.

“Right,” the mechanoid said, her voice sweet and oozing a sexual undertone. “It is twenty minutes of weightlessness, and during that time, you will have very little control as to where you go in the sphere. To help, you wear this belt, which has three grab handles and five thrusters built into it.”

Keith and Leanne looked at the wide leather belt the mechanoid was holding. The three handles were located one at the rear and two on either side of the body, while the thrusters were equally spaced. Now that they were committed, Keith and Leanne put the belts on. It was the only item of clothing they currently wore, and the mechanoid showed them how to operate the thrusters.

“Now it is time to choose your options.”

“Keith, if we are doing this, then I will be making the selections.”

Her husband instantly agreed, his mind only thinking about what he was going to see.

Leanne looked through all the different choices, selecting the default ones on all of them until she came to the bisexual option. She had never been with another woman, but suddenly she felt a desire to try it.

“Keith, do you want to see me with another woman?”

The question surprised her husband. However, with his biggest sexual fantasy just about to happen, his cock was now thinking for him, and he could only enthusiastically nod.

Unseen by Keith, Leanne made a couple of additional selections and handed the digital screen back to the mechanoid. Then, with little fanfare, they stepped inside the large, softly padded spherical playroom.

As instructed, they took their place on the handrail that ran in a circle around the bottom of the sphere. Standing with them were another ten naked couples, each looking at the other as the ever-changing pastel-coloured lights illuminated them.

Keith and Leanne knew that some of the couples were like them, real couples, while others were lifelike mechaniods. However, from a distance, they had no way of knowing who was human and who was a mechanoid.

As they scanned the scene, Keith wished he had paid more attention to the selections his wife made, particularly when he noticed that there were also two single men present. One was black, fit and completely naked. The other was white, dressed in black leather chaps, a neckerchief, a cowboy hat, and nothing else. Like all the men, they were both supporting atmosphere-fuelled, drug-induced erections.

Their presence had Keith increasingly wondering what options Leanne had put in for them. He was just about to ask her when the room went dark and a digital clock with white numbers started to count down in front of them.

TEN…

“Are you ready for this?” Leanne excitedly whispered.

NINE…

“Yes,” her husband replied, suddenly not so sure.

EIGHT…

“Keith, hold tightly onto my belt.”

SEVEN…

Keith tightened his grip.

SIX…

“Remember, Keith, to start with, it is sex only with each other.”

FIVE…

“We might have a free pass…”

FOUR…

“… But I want my first weightless fuck to be with my husband.”

THREE…

“Stay close to me, Keith.” Leanne was now extremely horny.

TWO…

The removal of the gravity-inducing system made their bodies feel suddenly lighter.

ONE…

Keith wondered if the moment had arrived when he would see his wife of twenty-five years with another man… or maybe another woman.

ZERO…

The background pastel lights turned back on, and their colours once again continued to change slowly as weightlessness took over. Their feet floated off the ground. The only control was their grip on each other's belt handles and their hold of the circular rail.

Then, as gentle background music filled the room, the rail that they were all holding retracted, leaving the twelve couples and two men floating just like they were in space.

“Stay close to me,” Leanne whispered once again.

Keith used his wife's belt handles and slipped effortlessly between her open legs. Leanne’s pussy was wet and inviting as his painfully rampant cock slid into it, his wife's legs wrapping around him to make sure they remained docked.

“Fuck me,” she whispered.

Keith realised for the first time just how difficult it was to have weightless sex. He chuckled to himself and looked around for inspiration.

There was a constellation of couples in the centre of the spherical playroom. His eyes took him to a woman holding a long cock with one hand to steady herself while another man was attempting to fuck her shaved cunt.

Then he heard Leanne giggling; she was looking at a couple who had been fucking doggy style but were now spinning, having accidentally knocked one thruster to full blast.

With renewed concentration, Keith used the two grips under his wife’s arms and started to build up an effortless momentum as his cock thrust in and out of Leanne’s pussy.

Floating there in space, Keith’s rhythmic fucking action soon brought the normal encouraging sexual sounds from Leanne. But there was nothing normal about this as they were slowly drifting across the playroom, passing other couples doing the same.

An older white woman was moaning, her eyes closed as a younger black man earnestly fucked her in the same sexual position as Keith and his wife were in.

Leanne muttered, “I like to try him next,” which only spurred on her husband, both of them now close to cumming.

Then there was a bump, which caused Keith to miss his stroke and almost lose grip of his wife. It was the cowboy. He was still wearing his chaps and hat, but more worryingly for Keith, his hard cock was jabbing into his backside.

“Want a threesome?” the cowboy questioned.

As Keith tried to brush him off, he noticed the new guest had cold, glassy eyes and that under his cowboy hat, he was completely bald. It was a mechanoid.

“Not with me,” Keith anxiously replied as the cowboy's cock probed his bottom for the second time.

It was an action that had Leanne giggling, as her husband’s cock slipped from her pussy.

“Threesome,” the cowboy mechanoid said once again as his cock tried once again to find Keith’s rear entrance.

Keith shoved him off, causing both him and his wife to spin in the weightless environment.

“Leanne, what did you tick on the option questions?”

His wife giggled as they spun.

“I am not into men!”

“I know Keith…” Leanne chuckled. “Maybe I should have been a bit clearer when I pushed that bisexual option button,” she added, knowing she had not excluded her husband.

The cowboy returned, his cock menacing and pointing towards Keith’s arse. With a whiff of desperation, Keith used his belt thruster to spin both of them. It put Leanne between him and the prodding mechanoid.

“That’s chivalrous!” Leanne exclaimed, and then she looked back and saw the size of the cowboy's cock. It was far larger than her husband's.

She took hold of it and eased it into her now wanton pussy.

“A threesome?” her husband asked a smile now etched on his face.

“Oh, yes…” Leanne murmured, partly in response to her husband, but mainly due to the sensation of her pussy being stretched. The mechanoid's cock was reaching places inside her that had never been touched before.

Keith kissed Leanne and then spun around so she could take his cock into her mouth.

The cowboy mechanoid began to fuck his wife as Keith lay along Leanne’s body, his head now between her legs. He had the perfect position to watch his wife’s pussy take its first new cock in twenty-five years.

As they floated across the weightless sphere, the cowboy thrust almost mechanically in and out of Leanne, sending gratifying sensations through her body. With Keith holding her, his dick was now effortlessly fucking his wife’s mouth, while his eyes took in the large cock now shagging her into submission.

As the three of them drifted and slowly spun in their sphere orbit, Keith felt his jism rise. He warned his wife that he was going to cum, but Leanne seemed not to hear him. She was too busy experiencing the pleasure of having two cocks for the first time.

Then, with a grunt, Keith ejaculated into her mouth, Leanne trying her best to swallow it down, although there were globules left floating in the air around them. Then, with the mechanoid still ploughing her, Leanne cried out as an orgasm ripped through her body. Keith did his best to keep hanging onto her as she bucked away, the cowboy mechanoid still expertly riding her.

It was like the cowboy mechanoid had been programmed, as, on hearing Leanne’s sexual cries, he started to grunt. Then, without warning, he pulled out of her and blasted his ejaculate towards Keith’s face. As the jism splattered him, in horror, he hit his belt thruster button, sending the three of them into different orbits.

While Keith and the mechanoid bounded off the spherical wall, Leanne was sent spinning straight into the cluster of couples enjoying their big bang in the middle of the sphere. There she was caught by the big black man whom she had commented on earlier.

Keith pushed his thruster button once again, trying to float over to her, but he was out of gas. He could only observe Leanne while he waited to get near the sphere wall so he could push himself back towards her.

Now on his own, Keith watched his giggling wife be slowly seduced by the big black man. As he looked on, he took his cock into his hand and slowly masturbated as he watched. Leanne soon had her legs wrapped around her dark lover's back as his big black cock started to pound her pussy.

This was his fantasy, and as they fucked, his wife in raptures of erotic pleasure, Keith started to realise that it was fast becoming his wife’s fantasy too.

With his hand picking up the rhythm, Keith fisted his cock in time with the unknown black man, each thrust into his wife being met with one in his hand. Then, after what seemed like an eternity of raw fucking, he recognised Leanne’s orgasmic cries as she started to cum.

Keith pumped harder. Then there was a grunt and a shudder as the black man started to cum in his wife’s pussy, the sphere echoing with her cries of pleasure.

It was the trigger for Keith to ejaculate into the weightless air of the sphere as he continued to watch the unknown black man doing the same, though into his wife.

As he recovered, Keith bumped into the sphere’s wall. So he turned and pushed himself towards his still-engaged wife. However, as he travelled towards her, Keith started to feel heavy, and he realised that the background music was now a voice counting down. The gravity-inducing system had reactivated, causing everyone inside the dome to gradually descend.

Grabbing Leanne’s hand, he pulled her close, and moments later their feet found the floor. Then, without warning, Keith’s previously floating jism landed on his head.

Leanne started to laugh.

“Well, it is meant to be lucky!” Keith remarked.

It was not until they were on the shuttle the next morning, as they left Euphoria Island, that Leanne brought up what happened in the pleasure dome.

“Keith, I think you are going to find us having another lucky win on the daily solar system lottery. As I have already mentioned, it is not only you who has access to the interplanetary web and therefore the interstellar black market.”

Her husband’s jaw dropped open as he realised that Leanne had known all along that he had paid for tickets to visit Titan’s Euphoria Island and its pleasure dome.

Then with a wink and a smile, Leanne added, “And I think it will be for more than one night!”
