Charlie grunted as he thrust into his wife, Erin, from behind, relishing the sight of her curly blond hair bouncing with each push. She lay with her arms flat on the mattress and her face pressed into a pillow and he loved watching her upturned ass, still pink from its flogging. He loved the sound his hips made as they slapped against the backs of her thighs and of her muffled moans as she groaned into the pillow. He loved the taste of her pussy still in his mouth and the feel of her soaking wet cunt as he thrust his rigid cock rapidly in and out of her.

“Oh. God. Charlie!” Erin gasped in rhythm to his pounding. “Fuck. Me. Ungh! Yes! Fuck your dirty! Show-off! Slut!”

That did it. Grabbing Erin’s hips with both hands, Charlie gave one final push and with an animal groan emptied his load into her wet, eager pussy.

As Charlie caught his breath and his muscles started to slacken, Erin slowly slid herself off his cock and collapsed easily into the mattress, stretching her legs out behind her so she was laying flat on the bed. Charlie rolled beside her and she snuggled into his shoulder, letting out a happy little sigh.

“That was fun,” Charlie said softly into Erin’s ear.

“Mmmmmhmm,” she cooed dreamily. “I feel all rubbery.”

Charlie smiled and pulled her closer to him. They lay in silence for a minute, Charlie listening to the sounds of birds outside the window. He wondered about the last week with Erin. When she pulled up her skirt and flashed her butt plug at him while they were out for a walk in the park. When they went to the movies, she pushed his hand between her legs until rubbed her clit to a wet, hushed orgasm right in the back row of the theater. It seemed like every day she came up with a new idea to try as she leaned hard into the blossoming of her sexual imagination. Charlie was just about in heaven.

Erin stretched and hopped off the bed, then pulled on her lacy black panties, which she had retrieved from under the bed.

Charlie propped himself up on one elbow and watched her. “Wait,” he started, “don’t you usually…?”

“I want to feel it for a while,” she replied. She turned to face him and struck a pose, shifting her hips to one side and biting her lower lip. “I like when your cum drips down my legs.”

She broke into a giggle. “Besides,” she said, “I want ice cream and walking around with cum in my panties makes me horny. So let’s — oh!”

She looked surprised for a moment then smiled mischievously.

“Mm, it’s coming out… come on, baby, let’s go!”

Heaven.

——————————————————————————————————–

Two days later, they arrived at the studio for their fourth and final session with Yvette. Though the out-of-the-way street that the studio sat on was usually very quiet, this time the uber had to circle twice before finding a place to drop them off because of all the cars lining the narrow street.

“This is so weird. Do you think there’s something going on at some … like, other place?” Erin thought aloud.

Charlie looked up and down the block at the unmarked, low-rise buildings that lined the street, looking for all the world like a semi-abandoned industrial park.

“Maybe…” he said. “Not sure where, though.”

Erin shrugged. “Just weird there’s so many cars here.”

The door to the studio had been unlocked, as usual. But Letitia, the pretty receptionist, was nowhere to be found. In fact, there was nobody in the reception area at all. It sat empty, the only sound or movement a single red flashing light on the desk telephone and the hum of a mini-fridge that sat in the corner.

Erin didn’t seem to notice or care, pushing her way through the door that led into the hall of changing rooms. Charlie took a last look around the empty waiting room and followed her.

A few minutes later he stood contemplating the collection of leather, neoprene, and metal laid out on the counter before him. There had been no note or instructions this time, which was a little unusual. But after a few sessions, Charlie felt like he understood the routine — leave his street clothes, and come into the studio wearing only what had been left for him in the little wicker basket in the changeroom.

In the basket had been two sets of cuffs, neoprene with leather straps and metal buckles. Exactly like last time.

In spite of himself, Charlie felt a little disappointed.

It wasn’t that he didn’t enjoy the cuffs. He just hadn’t expected Yvette to repeat herself.

Perhaps, though, he reasoned, it did not make sense to expect something different every time. He had certainly enjoyed the novelty of each of their previous sessions, but perhaps there was something to be said for doing things more than once, really getting into them over multiple sessions. So he’d seen these straps before — so what? Hadn’t he had a good time last time? Hadn’t he enjoyed being strapped to a chair, “helpless”, while Lexy teased him and Erin had her fun right there in front of him?

Of course he’d enjoyed it.

Charlie quickly stripped down to nothing, placed his folded clothes in the locker, and fastened the straps to his wrists and ankles, then strode through the studio door.

He was not prepared for what awaited him.

He found himself in the same familiar studio where they’d spent much of their previous sessions. But today, that familiar studio was dramatically less familiar. The red walls, black cabinets, and black rubber-panelled floors remained. But the queen-sized bed was gone, leaving a large open space in the center of the room.

Around the edges of the room were a dozen or so large, free-standing candelabras wrought ornately in black, twisting iron, each topped with five thick, white block candles that cast spidery shadows on the walls as they flickered.

A white and black shoji screen stood in one corner of the room. Charlie could see long, wooden four-by-sixes extending above the top of the screen, stained a deep walnut color and with metal rings bolted to them near the ends.

Along the far wall, a thick, black curtain had been hung from the ceiling, blocking Charlie’s view of a third of the room. David stood at one end the curtain, as ruggedly handsome as ever. And although his tight black jeans and black t-shirt had been substituted for a crisp, black collared shirt, black tie, and black trousers, he still looked for all the world like he was merely stopping by on the way to his nighttime show at a dive-y downtown rock club.

And then, of course, there were the four women standing in the center of the room. Erin caught his eye first, being that she was precisely as naked as he was, complete with cuffs at her wrists and ankles just like his own. The only difference between them was that Erin also had a leather collar on. She caught Charlie’s eye as he admired her and wiggled her eyebrows at him, pushing her hips out to one side in a sexy pose. He smiled back as she came to stand beside him and took his hand in hers.

With some surprise, Charlie also recognized Letitia, the receptionist. She wore a long, black, strapless dress, its sequined bodice slit down the middle between her ample breasts, which threatened to spill out over the top. She had cut her hair short since the last time Charlie saw her, and the new style beautifully accentuated the elegant curve of her neck, which was further adorned by a delicate lace choker.

Lexy was there too. She flashed her familiar, teasing grin at Charlie. As he finally really noticed her, his eyes widened. Lexy was pretty before, but tonight she was gorgeous. Her wavy brown hair was arranged elegantly on top of her head with two thick curls framing her pretty face. Her smokey eye shadow and plumped lips were dramatic, but tasteful. She wore a long, shimmering silver dress held up by thin straps and slit up the side so that when she moved, her leg was exposed nearly to her hip, revealing strappy high-heeled shoes that were silver to match the dress. The fabric of the dress clung tantalizingly to her luscious, and very clearly bra-less breasts, which gently bounced and shifted as she moved. She was stunning.

And then there was Yvette. Gone were her tight jeans, black boots, and black camisole. In their place, she wore a black wraparound dress, long-sleeved, with a plunging neckline and a slit as dramatic as Lexy’s. The dress’s neckline and slit were so long that they nearly met. The two sides of the dress were cinched in place by a simple, but elegant, fabric sash. Yvette, too, wore strappy high-heeled shoes in shiny, black patent leather. Her thick, shining black hair was down today and lay across her shoulders, standing out against her pale skin. Like Lexy, her make-up was much more conspicuous than usual, but no less refined and Charlie found her black eyeliner and wine-colored lipstick particularly striking.

“Hello, Charlie,” she said when he finally tore his gaze away from her outfit and made eye contact.

“Hello, Mistress,” he replied. “I guess it’s a formal affair tonight?”

Lexy giggled, Letitia grinned, and even David looked like he might crack a smile. But, as usual, Yvette’s expression did not change.

“Today is our ultimate session,” she said matter-of-factly. “And we’ve decided to make it something of an event. I’m glad to see the two of you were able to work out your accoutrements with no problems this time.” She punctuated this last thing she said with a pointed look at Erin, who sheepishly pinched her lips together and looked at the floor.

“Now that we are all dressed for the occasion,” she continued, “We ought to get started. I think our assembled guests have been waiting long enough.”

Charlie exchanged a startled glance with his wife. Guests? He looked over at the black curtain obscuring the far third of the room.

At that, Dominatrix Mistress Yvette came closer to cracking a smile than Charlie had ever seen her before. She nodded to Lexy who pulled open one of the wall-mounted cabinets and retrieved a six-foot leash made of brightly polished metal. She handed it to Yvette, who clipped it to Erin’s collar. She then clipped Erin’s and Charlie’s cuffs together so that the two of them were attached at the wrist.

Charlie’s mind raced as he allowed himself to be clipped to his wife. Assembled guests? What assembled guests? Who were they? How many? Would it be like last time? If so, what happened to the bed? And what was the curtain for?

There was a tug on his wrist as Yvette led Erin by the leash to the center of the room and Charlie was pulled gently along behind her.

Yvette stood them both directly in front of and facing the curtain, then stood next to them. Charlie’s heart pounded as he stared at the opaque curtain. He glanced at Erin, who looked back, wide-eyed and flushed.

“What’s going on?” she mouthed silently. Charlie just shrugged and squeezed her hand.

“David?” Yvette said.

David grabbed the edge of the curtain and crossed the room, pulling it back to reveal the rest of the studio.

Charlie’s breath caught in his throat.

In front of him was an audience of at least two dozen people, all dressed in elegant evening wear and seated on folding chairs. Many wore simple, black masks over their eyes; others were maskless, but all were impeccably well-groomed. This part of the room was also lit with matching iron candelabras and the flickering orange light cast dancing shadows across the guests’ faces as they took in the scene, some with hungry, lustful expressions, others with approving smiles, others nearly as impassive as Yvette. The whole scene had the feel of some secret, arcane society meeting.

As David pulled the curtain away, the assembled guests began to applaud. Charlie almost laughed and felt a little thrill go through his body. He was dimly aware that his cock had gone from semi- to nearly fully-erect. Some small part of him was self-conscious about this, but he was so overwhelmed by the scene that he barely noticed. He snuck a glimpse at Erin who looked as shocked and wide-eyed as he felt. He squeezed her hand and she squeezed back, pulling her mouth into a small, nervous smile before turning back to the audience.

“Good evening, my friends.” Yvette’s voice reverberated through the studio, causing the applause to die quickly away. “Thank you so much for coming, and welcome.”

Charlie was startled at Yvette’s complete change in demeanor. Instead of her usual stern scowl, she wore a graceful and welcoming smile. It was not the expression she’d had when she had first welcomed them to the studio before their “orientation”, however; it was more like she was a grand host inviting her assembled guests to behold the begin of some wondrous spectacle.

Not inviting, Charlie wondered. Commanding.

“We are pleased you are able to join us,” she continued, “for a night of fun and pleasure. I believe that you all understand the rules of our games for tonight …”

Games? Charlie wondered and stole another look at Erin, who stared out at the audience with wide eyes.

“So all that is left to do is introduce our … ‘props’ for this evening.”

Yvette tugged on the leash and Erin obediently followed, with Charlie following behind her. Yvette led them to one end of where the audience was seated.

“These,” Yvette said, “are Erin and Charlie.” She started to slowly walk the length of the audience, bringing her two “props” behind her. “We’ve been working together for several weeks now, and I’ve decided they are ready for game night.”

The guests were seated by twos and threes and they all watched intently as Erin and Charlie were paraded in front of them, murmuring a polite hello or giving a small wave as the two of them passed by. Charlie’s eyes darted from face to face searching for a safe place to land as each audience member stared intently back at him.

After what felt like ages, the trio had made their way down the length of the audience and Yvette led them back to the center of the room.

“Now,” Yvette said, “you’ll all have a few minutes to take a closer look at our props so that you can make a more … informed prediction. For now, please stay seated while we set up the preview space.”

“Prediction?” Charlie wondered. “What on earth is going on?”

He didn’t have much time to think about it. As Yvette finished speaking, there was a flurry of activity behind them and Charlie craned his neck around to see what was happening to see Lexy, David, and Letitia disappearing behind the shoji screen.

It took a few minutes, but eventually the three of them had finished setting up what Charlie took to be the “preview space.” In the middle of the studio there now stood two large, x-shaped apparatuses — the walnut-stained wooden frames that Charlie had noticed earlier. (Charlie wondered he’d heard these referred to as “St. Andrew’s crosses”.)

Between the two St. Andrew’s crosses was a small, round, high table with a white, faux-quartz top atop a narrow, stainless steel pedestal. On the table were arrayed numerous devices — a feather, a riding crop, a vibrator, something that looked like a spiky little pinwheel, and a variety of other implements.

As David and Letitia positioned themselves by the crosses, Lexy glided over to Yvette, who handed her the leash.

Yvette held up her hand and the audience — which had been murmuring with increasing excitement since the St. Andrew’s crosses emerged from behind the screen — fell silent.

“Now,” she said, when she was satisfied she had their attention, “while our props are prepared, let us take a moment to review the rules of the observation session. First, you will be allowed to interact with the props. You may speak with them, ask them questions, and so forth, to get a better sense of how they might respond to the game. You may touch them. However, you may not touch them anywhere that would be covered by a speedo or a bikini.”

The audience chuckled.

As Yvette spoke, Lexy led Erin and Charlie over to the St. Andrew’s crosses, where she and Letitia disconnected them from each other and guided them each onto one of the apparatuses. They were bound at the wrists and ankles so that Charlie found himself standing spread-eagled with his wrists bound above his head and his legs immobilized at the ankles.

“Second,” Yvette continued, “you may use anything you see on the table to interact with the props; however, you are not permitted to strike them.”

Charlie wondered he heard a groan of mock disappointment from somewhere in the audience.

“But third,” said Yvette, “you may ask either David or Letitia to strike them — gently.

Fourth, you have only ten minutes to make your assessments, at which point all predictions must be registered with me if you want them to be counted.”

Charlie suddenly noticed she was now holding an iPad. He hadn’t seen her retrieve it and hadn’t the foggiest idea what sort of “predictions” she was gonna be recording on it. Things were getting more and more strange.

“And fifth,” Yvette said, “since time is limited, you are permitted only one question or interaction per prop — David will be there to help you keep track, should the need arise.”

There were murmurs from the audience.

“Are there any questions?” Yvette asked. She paused and surveyed the room. Nobody moved.

“Very well,” Yvette said, “let us begin.”

There was a scraping of chairs and a rising clatter of voices as the assembled audience got up and began to make their way to the center of the room where Charlie and Erin were bound.

Most stayed a few feet away at first, clustered in twos and threes, studying the “props” from a distance and conferring together in voices that melded together into a soft, excited hum.

Charlie looked again at Erin, who was biting her lower lip, wide-eyed and breathing heavily. He felt a pang of worry until he noticed that David had positioned himself between the two crosses, but closer to hers. That, and Yvette’s watchful eye eased his concern.

His train of wondered was interrupted by a woman’s voice.

“Hello, Charlie.”

He turned toward the voice and found himself making eye contact with a curvy, red-haired woman dressed in a black skirt and a purple and black corset. Standing just behind her was a tall man in black jeans and a black collared shirt.

“Um… hi,” Charlie stammered, suddenly very aware of a slight breeze on his privates.

“We’d like to ask you a question,” the woman said.

“Uh… sure,” he replied, “what, um … what would you like to know?”

“Well,” her companion spoke up, taking a step forward. “I guess we’d like to know whether you enjoy being up there?”

Charlie wondered for a moment.

“I … yeah, I guess I do.”

“You guess you do?”

Somewhere to his left, Charlie heard David clear his throat. The man smiled.

“Thank you, Charlie,” he said.

The woman in the corset took a step forward. “I think I’d like to see how Charlie responds to that,” she said, pointing to a small wand vibrator on the table. Lexy, who had taken up a position between the table and Charlie’s apparatus, smiled and handed it to the woman in the corset.

It made a low buzzing sound as the woman switched it on and Charlie almost laughed out loud when she held it to his thigh. It tickled slightly, creating a warm, tingly feeling in his leg. A bit like having pins and needles but without any pain.

“That … that kind of tickles,” he said to the woman.

She smiled at him and switched off the vibrator, handing it back to Lexy.

“Good to know,” she replied. “Thanks, Charlie.”

The couple stepped away from Charlie and moved over to join a knot of people who were watching the other St. Andrew’s cross and Charlie took benefit of the momentary lull to see what was happening with Erin.

She was surrounded by a much larger group of people. Charlie couldn’t complain about that, if he was in the audience he too would be most interested in the pretty blond woman bound with her chest pushed out and her legs lewdly spread.
