As Finn and Catlyn timidly entered the back room of the inn, they were both nervously eying the invitation they'd received in the post. It shimmered in the room's dim ambience, clearly wrapped in a variety of discretionary spells. Without a doubt this night would be the most adventurous thing they'd ever done together, and only thanks to the chance meeting they had with the wealthy traveler at the prior Festival of Lights.
"A Cordial invitation to The Carnival of Sin, Admits Two"
They looked at each other and with only a moment's hesitation dropped the invitation into the fireplace against the far wall. The normal burst of blue flame was a relief- at least THIS part was normal- and hand-in-hand they stepped through the newly conjured portal into a night they'd never forget.
They'd been wed for ten years. Finn spent his days in the town library, helping to archive the various books and scrolls that made their way to their humble corner of the world. Catlyn was known in their region for her beauty, her talent as a singer and yes, her body. She didn't perform often but when she did, whatever tavern she graced would be packed to spilling over, men admiring her elegant features, beautiful voice and sensuous body. Catlyn knew Finn didn't mind men ogling her, but she often opted for modest clothes, keeping her curves obscured. Although she could earn a month's wages in tips if she showed off more, she believed her body was for Finn's eyes only. That was about to change.
At the Festival of Lights two moons past, Finn and Catlyn had been a few drinks deep at their local tavern when they got to talking with a well-dressed man from out of town. He was tall and broad, with handsome features and a deep voice- he spoke sweetly to them, telling them about his various adventures around the world, many of which with a hedonistic twist. The man made no effort to hide his interest in Catlyn, who'd opted that evening for a slightly more revealing dress, which hinted at her body's contours and the generous swell of her full breasts. Catlyn didn't seem to mind his leers, however, and gently rested her hand on Finn's arm, quietly letting him know everything was fine. That was when the man mentioned the Carnival.
They'd never heard anything like it-- an anonymous and sordid evening of voyeurism and group sex. Go and fuck or be fucked to your heart's content, or simply watch as the events unfolded around you. Any and all were welcome, but some, he added with a lingering look at Catlyn's large chest, were more welcome than most. Finn was speechless. He'd only ever had Catlyn as a partner and beyond occasionally hearing neighbor's lovemaking through open windows on hot summer nights, the idea of witnessing someone else having sex was a foreign and, despite his reservations, exciting idea. Catlyn, too, had a blush on her cheeks and upper chest, and her breathing had gotten quicker. The man continued talking, painting a picture they'd go on to talk about in hushed tones for weeks afterward.
Almost a month later, both were surprised to discover that the other was still thinking about the Carnival, and in bed together as they gently made love, Catlyn was the first to admit she would be curious to go. Finn immediately finished inside of her, shuddering at the rush of emotions. His meek wife wanted to visit the Carnival of Sin? He didn't answer her, but was soon hard again and they quickly tumbled into round two. The next morning they found the invitation in the mail along with the gentleman's best wishes, and they only discussed the matter briefly before agreeing to go-- not to participate, of course, just to go and watch. That was the agreement.
After the cozy warmth of the Inn, the broad expanse of night sky above their heads was a shock. The night air was warm, almost unnaturally so, and their clothes felt unusually restrictive. They'd arrived at what seemed to be a grain field, where a wide open patch had been cleared for guests' arrivals. Ahead of them there was a tall fence with a checkin counter, wooden and well-constructed, with a revolving gate to its left. Finn and Catlyn remained still, hesitant to take their first steps. Were they really going to do this? A feeling of static in the air built around them and soon another couple popped into existence with a blue flash a few feet to their right. The new couple, clearly carnival regulars, smiled at them before walking merrily to the check-in counter. After a brief conversation, they headed through the revolving gate and toward what Finn and Catlyn had spent so long discussing but still couldn't picture. Finally, they mustered their courage and approached the desk.
"First time?" The young woman at the desk asked, her voice smooth like honey, and low, sending a tickle up Finn's back. She was beautiful- lithe and her feature's weren't as elegant as Catlyn's but she was still lovely, and eyed the young couple hungrily. Finn suspected she'd just as happily take Catlyn to bed as him, and as he watched her continue to eye Catlyn's body he knew he was right.
"Y-yes. Do we- do we go through that gate now, or is there, a mask or something?" Finn's voice faltered, and Catlyn rubbed his arm, pressing her body to his protectively.
"An excellent question," the woman purred, leaning forward, "the gate contains several enchantments and when you pass through they'll bind themselves to you until you leave. Simply put, first, anyone outside of your party," she gently indicated the couple, "won't recognize your face, even were they to gaze into your eyes. Your anonymity is protected and you're free to act however you've always desired."
The woman reached out and took Catlyn's hand, lightly dragging her fingers across Catlyn's wrist. Finn didn't object, watching as his pulse quickened.
"Your personal belongings will be kept safe, replaced by Carnival-appropriate garb," she kissed Catlyn's palm, "and of course you'll be protected against all transmitted diseases, so you can take as many partners as you want." Catlyn didn't pull away, and was breathing harder, her full breasts pressed against his arm as the booth attendant continued to tease her.
"Any other questions?"
Catlyn and Finn could only shake their heads, no.
"Then, I must tell you finally that the Carnival has rules. Your anonymity is protected but there will be members of security monitoring your behaviors and your moods. Every act of indulgence..." the woman nibbled at one of Catlyn's elegant fingers, "...has its place. If you don't respect the rules, your fate is in security's hands."
Finn had questions, but was transfixed at the woman's behavior. Catlyn meanwhile was clearly enjoying the attention. Without any further questions the woman lightly kissed Catlyn's hand once more, took their ticket, and one at a time they passed through the revolving door.
On the other side they took a moment to collect themselves. As promised, their clothes began to change--as Finn watched, Catlyn's garments became gossamer, shimmering and transparent, reduced to a singe cloak, that shifted in the breeze. For himself, his wool trousers and shirt were gone, replaced by a solitary light loincloth of a similar, transparent material, and much to his embarrassment he realized anyone who looked could see his penis. With the knowledge that any passing man might look at Catlyn's nearly naked body, her flat stomach and heavy breasts, her perfect round ass and firm shapely legs, Finn began to get hard, despite himself. The transformation didn't stop at the clothing, however-- the hair began disappearing from both of their bodies, and in the flickering torchlight Finn could swear their bodies had become oiled, the gentle smell of honey teasing his nostrils.
Catlyn didn't acknowledge her new appearance, and was still collecting herself after the teasing from the counter. After a moment, she took a proper look around and gasped. Finn followed her gaze. His jaw dropped.
They'd entered a fairground, with tents and small structures scattered under the expansive and beautiful night sky. There were hundreds of guests walking around, all of them in similarly revealing garb, some in obvious states of arousal. Many of the stories they'd heard from the gentleman immediately proved themselves true--shadowy corners being used by enthusiastic lovers, small stages set for performers, and lesser acts of intimacy anywhere you looked. Some of the exhibits were clearly aided by spells, portals bringing the professional Carnival Performers' bodies to within arm and mouth's reach of guests, others magically obscured from view, shimmering barriers leaving only a faint impression of the hedonism within.
Catlyn and Finn were speechless. In their lives they'd never imagined seeing another couple have sex, let alone the number on display in front of them now, and the shapes of bodies! Every imaginable physique was present, from the portly to downright pornographic, from bodies that drew you to them to bodies you'd just as happily forget. Nevertheless, with anonymity, the thousands of strangers milled about, comfortable in their skin. Confronted with hundreds of comparisons, Finn couldn't help but marvel anew at Catlyn's body. She immediately stood out among the crowd, and it wasn't long before Finn began to notice men glancing over at her, idly stroking themselves to the sight of her pillowy breasts under the shimmering cape.
Catlyn, meanwhile, took note of the many male physiques she'd never considered before tonight. Finn was very attractive to her, but was narrow in his shoulders, thin and lanky, without an ounce of extra muscle anywhere. She'd seen men rinsing in the river with broader chests and thicker arms, but she'd never imagined such a wide range of physiques possible, let alone the variety of cocks! Finn satisfied her, but his cock was thin, only an inch or two longer than her fingers. Among the many strangers, she saw cocks twice the length and soft, swinging heavily as their owners meandered about, with partners or without. It was going to be a very interesting evening.
The couple tentatively stepped forward, hand in hand. Finn wondered at Catlyn-- if she'd noticed her outfit change, she didn't seem to mind it. As they moved, her breasts shifted under the garment and his erection twitched involuntarily at the sight. Once again, he glanced around, taking note of the men (and women) who followed Catlyn hungrily with their eyes.
The layout of the Carnival became more apparent as they strolled. The earliest exhibits seemed to feature mostly the Performers, professionals in the sensual arts, whose bodies acted as entertainment for the Guests. The later exhibits offered opportunities for Guests to take center stage, and along the periphery were benches, beds, chairs and more-- opportunities for those inspired to find a moment of intimacy with whoever had caught their eye.
