A First Time for Cassie

Contradictions make for some wonderful sexual tension. Looking over at Cassie as I waited for the lights to change it was hard to see the turmoil, but I knew the tells and she was definitely in a spin. For someone who liked to be in control (but not 'in charge' as such), this was a level of mental torture similar to going to the doctor for an unexpected referral. Actually, when I came to think of it, this was very similar, and with that thought I stifled a grin.

"Honey..." she began, but I jumped on that shit right away.

"For the tenth time," I said with good-natured exasperation, "I have no idea what they're going to do. They haven't sent me a script, and I doubt they even have one."

Cassie slumped in the passenger seat with a cute little pout. I could see she knew I was right, but that didn't mean she liked it. It was one of the little pleasures of setting up an adventure for someone who needed to know what was going to happen: today, she was going to have to let go. Not that it would be easy, but then she did also say she liked things to be spontaneous. Hmmm... we almost split up early on -- it was impossible to take her to the cinema without a barrage of questions about how the film would end, and that was before we had even sat down. And that's just one example of things that exasperated me about her until I learned to accept her for who she was.

The lights changed and I drove over the bridge to the east side of the city with the rest of the lunchtime traffic. There was a cheesy metaphor somewhere between me driving Cassie to where we were going, over a broad silver river carrying torrents of meltwater from the distant mountains out to the Baltic, hundreds of miles away. I decided, wisely I think, not to mention that to my literature PhD candidate girlfriend, instead giving her a smile as she gazed out at the river, the tip of her thumb between her lips and betraying her anticipation.

She didn't know where we were going, though she certainly knew why, and that ignorance added something else to her tension. I knew, however, and I decided now was the time to tell her.

"We'll be there in five minutes or so," I said, "we can still turn back. Nobody will hold it against you, and I can take the guys out for a night on the town instead."

She shook her head, and I think the excitement had got her tongue -- a cat on a hot tin roof.

"Ok, well, just a final reminder," I went on, "they know your red lines, and they know your safe word. I trust these guys, and I'll be there anyway, too. Horny?"

She nodded, and then she let out a breath in a long stream and I knew that she was composing herself.

"I wouldn't do it without you there," she said, giving me a cute smile, "thanks for arranging this. Probably."

"Hey, you can stop any time you want."

"I know," she said, "let's hope I don't want to."

I turned the car off the main road and into the smart riverside district where the townhouse was. It was a rental place, very expensive, and equipped specifically for those in the know. The owner occasionally put on open events, rather in the manner of fetish clubs, but mostly it was for private hire. I had hoped to take Cassie to one of the club nights the year before, to make a change from the swinger clubs we went to, but I came down with the flu, and then Cassie caught it from me. Hardly conducive to a night of wild fun...

The satnav sent me down increasingly quieter streets until we reached a side street that even the locals probably forgot about. It was short, with only about ten widely-spaced houses on each side before the street ended in a T-junction. But those houses... I could only dream of owning something like them. They were all tall -- four storeys -- and had large walled gardens. Everything was whitewashed and scrupulously clean.

I pulled up in the street and sat for a moment, silent with Cassie.

"Are you getting out?" I said, and it really did need to be her choice.

"Yes," she said, after a pause, and then more definite, "yes."

She got out of the car without waiting for me to get her door for her, and stood in the street as I grabbed our small suitcase of toys from the boot. She looked great, and certainly fitted in with the area: despite me saying that she needn't dress up, she had chosen a dark skirt suit she wore to conferences, and a pair of two-tone heels. The heels pushed her up towards my height, and I'm six-foot dead, and with her shoulder length blonde hair and slender figure she really did look like a model -- not a catwalk, supermodel, mind, but one who would easily get the lower end jobs. Smart and pretty... yes, nobody needed to tell me I'd got lucky.

I led her over to number four, to the small gate next to the heavy driveway gates. There was an entry phone, and I pressed the button and I could feel her agitation as she virtually bounced on the spot in silence. Then we were buzzed in and I pushed open the gate, ushering Cassie through and following her up the short flight of stairs to the quite imposing black front door.

Inside we were immediately faced with the owner in the small foyer. I had only contacted her via email previously, but I knew something of her by reputation. She was from somewhere on the eastern edge of Europe, a stereotypically stern, tall, beautiful Slavic woman in her thirties with precious little in the way of human warmth. Or at least, so it seemed when she was speaking to me, outlining the rules of the place regarding smoking and damages and the like, and the drinks we could take in the bar. But when she glanced over at Cassie, I saw the slightest flare of her nostril. Aha, thought I, that explains a lot.

I handed over the remaining, rather large pile of cash required to hire the place on top of the deposit I had already transferred to her and she checked it meticulously. And then she was gone after reminding me that we had the house until six.

We walked through the door connecting the foyer to the rest of the building, and there waiting in a bar area were my friends sitting on a smart grey leather sofa with a coffee table in front of them. I had arranged for two guys to come and dominate Cassie, Alex, a friend from my old life back in London and Matt (which he preferred to Matteo), a more recent acquaintance from the months I'd spent working in Vienna the year before.

Alex was quite a slim guy, and not too tall either, with close cropped dark hair. But whilst he wasn't God's gift, exactly, he reeked of relaxed competence, as if every smooth movement had been meticulously considered and perfectly executed. He was on the verge of forty now, and I knew that would be another plus as far as Cassie was concerned as she liked older guys. But as always, the real winner was Matt, about five years younger than Alex.

He was the son of a Nigerian father and an Austrian mother, and being a light-skinned black guy with blue eyes he had women everywhere falling at his feet. It irritated him sometimes, and I could understand why, but I loved taking advantage anywhere there was a woman in charge of customer service. It didn't hurt, either, that he was buff and had short dreadlocks, and a winning grin -- I mean, dude, if you want to be loved for your mind, at least buy some non-prescription glasses!

Alex and Matt had, I noticed, also dressed a little smartly for the occasion, both of them in dress shirts and trousers, not jeans. It was serendipitous, an accidental show of respect for the effort Cassie had made, just as her outfit complemented the location. Even I, I suppose, had subconsciously made an effort, wearing something similar to the guys.

They stood up and we had a bit of a group hug and a friendly shaking of hands and the like. By sheer luck Alex and Matt knew each other vaguely from the lifestyle, and we shot the shit for a minute or two, all the while with Cassie standing ignored, off to one side. Normally, I wouldn't have countenanced anyone excluding her, but right now... well, she had to know her place.

"You weren't lying when you said this place was fully equipped," said Alex, and I could see that he was getting some ideas -- he owned a BDSM suite in London which he rented out to people on the scene.

"Yeah, we've been having a bit of a back and forth," said Matt, "I want the top floor and he wants the basement."

"I've only seen it on the website, actually," I said, "what was the basement, again? It's the fake prison, isn't it?"

"Yeah, it's beautifully done" said Alex, "and the top floor is the classic set up. We're going to flip a coin."

"Anyway," said Matt, "we're pretty much set, so..."

"Hang on," I said, and I went back to the foyer and collected the small suitcase I'd brought.

"Not you, too?" laughed Alex, and he retrieved his own case from behind the sofa where they'd been sitting, and a second later Matt got his from the same place.

"Yeah, I guess we'll have enough stuff," I grinned. Matt nodded.

"So, as I was saying," he began...

* * *

It had taken me weeks to set up this afternoon, and once Alex and Matt had shown their interest, we got together on Zoom to talk everything through. No piss, no shit and no blood had been Cassie's main outline, apart from the usual safe, sane and consensual, and then the guys had said what they wanted -- obedience, basically, and the chance afterwards to have some friendly chill out time and a bit of sightseeing in a city they hadn't visited before. That wasn't a problem, so I sent them a picture of Cassie, and they liked the look of her, and then I bought them tickets and reserved hotel rooms, and her birthday treat was definitely pretty much set.

"I just want to double-check," said Alex, before we ended the Zoom, "that she knows a bit about what she might be getting into."

"Yep," said Matt, "she's got some experience, I hope. Sometimes people overestimate what their partner is comfortable with."

"Well, we've done some stuff at home, some whipping and bondage and nipple clamps and stuff."

"And she liked it, I guess?" said Alex, at which I nodded. After all, we wouldn't be having the conversation if she hadn't.

"What about something with more than one person?" said Matt, "that can freak people out, and if it's the first time you never know how they'll react."

"I know, but she's had a couple of threesomes, as well as a thing with three guys at once before now. Admittedly, that was in a swinger club and was straight fucking, but she absolutely loved it. She surprised me actually, at how much she let go. I mean, we've swapped before, but this was different. She was on cloud nine for days after."

"Sounds like she'll probably be alright, then" said Alex, "but you'll keep an eye on her. You know her and you'll see if she needs a break, or to stop. So, don't get too carried away watching, and stay switched on. We'll be relying on you a bit."

"I promise," I said, and I smiled, thinking about how I could simply sit on the sidelines and let Alex and Matt take the strain.

It had been her idea, or rather, it had been a wish she had idly vocalised, to have a hardcore session with someone other than me. We played sometimes, and of course, we swung, but when it came to the dominance and punishment side, she felt it didn't quite work, that there was something missing. I agreed -- I'm no top, really, and I don't pretend to be. Usually, by the time she really got into it I would be running out of ideas, and it began to feel like work.

However, whilst I may not be master material, I know a man, or rather men, who are. Furthermore, through an unlikely to be repeated set of circumstances, they were both single. It was now or never, probably. And when I asked her if she would really want it if I could organise it, she had spent a few days turning the idea over in her mind and then given me the go ahead.

"Ok," I said, "if you're sure. You'll have to do what you're told."

"Yes," she said, a hint of the nervous virgin in her demeanour, "that's why I want it."

When I suggested that I might be able to get two friends to come, rather than one, and they could both give her a workout her eyes widened. Rather than turning a second man down flat as I expected she raised me.

"Go on then," she said, "but I have one condition."

"I'm listening."

"You have to watch," she said, "you have to be there as my security."

I nodded. I knew how much she liked being watched in the swinger clubs. Whether she was with me or with someone else, when there were other people in the room and she was stripped naked it turned up her arousal a few notches.

"I wouldn't miss it," I said, which brought us to the there and then.

* * *

It was time to introduce Cassie to the guys, and I did so, bringing her forward from the background where she had been dutifully waiting. I could see she thought Alex was interesting and Matt was hot. So far, so good.

"Hi, Alex," she said and kissed his cheek as they shook hands.

"From now on, it's 'sir', thank you," said Alex, but not unkindly.

"Same for me," said Matt, and he kissed her hand like an old-fashioned aristocrat then held it high, "now, give us a twirl."

She did, and she was quite graceful, her years of dance lessons paying off. It was clear she fancied Matt, as they all did, and that would hardly hurt the afternoon's activities.

"Let's check the rules," said Alex, "no cheek or answering back. Your safe word is 'red'. Your tits can be sensitive, so we should be careful not to squeeze or crush them, but nipple play's ok, and you aren't a fan of gags. That's right, isn't it?"

"Yes," said Cassie, and I smiled inwardly -- that was her first mistake.

"Yes?" said Alex.

"Yes, sir," said Cassie, correcting herself, and there was a little twinkle in her eye.

"I've got one more," said Matt, "if there's something you want us to do to you, like, you're thinking, 'I really wish they'd fuck me right now', and we're doing something else, then you have to ask. But ask nicely, and we have to believe you want it."

"Doesn't mean we'll do it, either," said Alex with a grin, "but we might."

Cassie glanced over at me for my approval, but I was already stepping back into the role of observer.

"Don't look at him, he's off-duty now," said Matt, "you look at us. Is that clear?"

"Yes, sir."

"Now," said Matt, "I'd like a drink before we begin. Vodka and tonic."

He nodded towards the bar, and it took Cassie a moment to realise she had to get it for him.

"Would you like a drink, too, sir?" she asked Alex, and honestly, I felt a little proud that she was a quick learner.

"Just a coke, and..." here he looked at me.

"Scotch and lemonade," I said, and Cassie turned to go to the bar as we took our seats.

"But it needs to be served naked," Alex went on, and Cassie stopped.

I saw her swallow as it struck her that the scenario was really beginning, and then she slowly unbuttoned her jacket. She was standing next to chair, and she draped her jacket over the arm. Next, she unbuttoned her blouse and slipped it off, placing it on top of her jacket. Alex and Matt watched her all the while, letting her see they were eating her up with their eyes.

She was wearing a sheer cream bra beneath her blouse, and it framed her tits wonderfully, and showed off her dark nipples. I loved her tits, not too big but not small, and I'd spent much time playing with those nipples, still perched quite high. At twenty-eight she was still firm, but one day we would both be saggy. That wouldn't matter, I already knew, for I would still desire her as I desired her then. And glancing at Alex and Matt I could see they desired her in that moment, too.

Cassie unclipped the bra and slid it down her arms, and I could see she was caught between two feelings -- she loved that we were watching her, but nonetheless she felt she should modestly cover herself. It was a battle with an obvious outcome, and after a moment she dropped the bra and stood, seeming to press her chest out with some pride. Good girl, I thought to myself.

Next, she unzipped her skirt, swallowing another little wave of nervousness. She slid the skirt down, showing us the matching sheer panties she was wearing, and the tan hold-up stockings. In all, I had to admit she had prepared very tastefully, and it was almost a shame it was wasted. But only almost -- she could dress like that for me any time, and having seen this outfit I would make sure she did.

"Panties off," said Alex, and she held his gaze as she reached for the waistband, then pulled them down.

She knew from our conversations that she shouldn't put her hands in front of her pussy, and she remembered, putting them behind her back and letting Alex and Matt see the thin strip of hair on her mons. I could see a little life in her cheeks now, and I wondered if she was already wet.

"Get the rest of it off, too," said Alex, meaning her shoes and stockings, "slaves don't have clothes."

She complied, and within a minute she was absolutely naked, her hands behind her back again as she stood, being idly scrutinised by us all.

"Now, get the drinks, slave," said Matt and Cassie promptly obeyed, going behind the bar and finding out where everything was.

"Have you got a coin?" Matt asked me, "it's only fair if you flip it to find out where we're taking her first."

"Sure," I said, "somewhere."

I fished around in my pockets and then searched through my wallet, but I didn't find a coin until Cassie came back from the bar with the drinks on a tray. She placed them neatly on the table, then returned the tray to the bar as we watched, and then she came back to us.

"Wait there," said Matt, pointing to one side of the table, and Cassie assumed a kneeling position -- again, something I had forewarned her to do.

"Legs apart," said Alex.

"Yes, sir," said Cassie, and she slid her knees apart on the rug. I marvelled at her automatic submissiveness. If I tried ordering her around, she would get cheeky in a heartbeat or more likely simply tell me to fuck off, but perhaps here, with men who were strangers to her, she was playing it carefully.

"Heads for upstairs, tails for the basement," said Alex, and I flipped the coin and let it fall on the table, bouncing and skittering until it came to rest.

"Heads!" laughed Matt, "I win."

"Yes, well, let's make sure we get some time downstairs, too. Deal?" said Alex.

"Deal."

We then spent the next few minutes sipping our drinks as we swapped some gossip about mutual acquaintances, and Alex and Matt speculated about why a particular Danish club that I'd never heard of had closed its doors. It was chatter we could have saved for later, but I knew why my friends were doing it -- we were keeping Cassie waiting until we were good and ready, reminding her she was there for us, though in reality this was all for her.

I glanced over at her and saw she was looking into the middle distance. It struck me at that moment that for all I knew her so intimately, I hadn't properly looked at her since.. who knew? So, I took a little time to see what Alex and Matt were seeing. My eyes followed the curve of her breast and then lowered to the slight swell of her stomach, and I studied the smoothness of her skin, promising myself I would explore her with my hands later. And, of course, there were her legs, parted, and the strip of pubic hair, and her holes, just out of sight. I began to feel the allure.

"Hey, slave!" said Matt suddenly, bringing both Cassie and me out of our reverie, "do you like your boyfriend watching you get fucked?"

Cassie didn't know what I'd told them, so she could hardly lie. "Yes, sir," she said, plumping for the truth.

"Hmm, I think I'm going to call her 'slut' instead," said Matt, and Alex nodded.

"I like him joining in when I'm getting fucked, too, sir," Cassie said, volunteering more information than I thought she would. Again, I studied her, and I could see she was turned on.

"Have you fucked any girls, slut?" said Alex, and I knew the subject was a favourite of his.

"Not enough, sir," said Cassie, glancing in my direction to see how I would take her answer. I was mildly surprised -- she had fucked a woman or two in swingers' clubs, but I didn't know (because she hadn't bloody told me, silly woman!) that she wanted more of it. Well, I was sure that could be arranged.

Alex nodded again, and I guessed he was imagining a random woman sitting on Cassie's face and gripping her hair. I was imagining it, too, if I'm honest, and for all I knew Cassie was thinking about it as well.

"Time we began," said Matt, putting his half-finished vodka and tonic down on the table. Alex nodded.

"Get up, slut," he said, and I smiled as I watched Cassie obey.

"The bathroom is over there," said Alex, "if you need to piss or shit, you should go now. Don't know when you'll get the chance next."

"Thank you, sir," said Cassie, and she left to go to a door near the back of the bar. We all watched her go, her arse moving beautifully as she walked.

We chatted a little more as we waited, and then Cassie returned, keeping her hands behind her back as she walked over to us.

"Just stop there," said Alex, as Cassie reached us, and she stood, obediently, "so, did you piss, or shit?"

Cassie glanced over at me again -- did she really have to answer this? Matt, though, quickly clicked his fingers to get her attention, pointing back at himself when she looked at him, and the message was reinforced: your boyfriend isn't an active part of this.

"I peed, sir," said Cassie after the briefest pause, and for the first time she seemed a little shy, looking down at the floor.

What I could see, and I hoped Alex and Matt could, too, was that his was a real give away. Cassie was getting into this, and she wanted it to go further, right away.

"Let's go upstairs, then," said Matt and Alex gave him a fake grimace of displeasure that we weren't going downstairs instead.

"Then you can take your case, and I'll take mine when we go down," said Alex.

"Fine," said Matt and picked it up while Alex took Cassie by the upper arm, preparatory to leading her to the stairs. Her breathing was suddenly a little superficial: clearly the butterflies were swooping through her stomach, and looking at her, I was ready and eager to watch the main event.

"Hang on!" said Matt, and he took hold of Cassie by the other arm. In one swift move he spun her to face the sofa and then bent her over the back of it, forcing a startled gasp out of her as the top of her head almost touched the seat and she stood on tip-toe.

"Hands on your arse, slut," said Matt, "and pull your cheeks apart."

As Cassie did what she was told, balancing on the top of the sofa back as Matt opened his case and rummaged around. A moment later he pulled out a small bottle and held it up over Cassie's tight arsehole. He squeezed the bottle and some lubricant dribbled down on to her. She whimpered softly, I assumed both because it was probably quite cool, and she could guess what it signified. Matt dropped the bottle back into the bag and then pulled out a black butt-plug, somewhere about medium size.

"Oh, no! Please, sir," murmured Cassie as Matt circled the tip of the toy around her hole.

"Keep them spread," said Matt, ignoring her. Cassie whimpered again, and pulled her cheeks a little further apart. At which Matt eased the tip into her, then pressed it further into her arse. Cassie gasped quietly, and I could see her trembling slightly. Surely Matt, as close to her as he was, could smell how aroused she was by now.

Matt pushed at the plug again, and now the widest part must have stretched her hole, as she moaned aloud, only for it to be cut off with a whispered, "Oh God!" as the toy sunk all the way up to the base into her anus.

Matt stepped back half-a-pace, then slapped Cassie's arse as she let go of her cheeks, and again she gasped.

"Get up," ordered Matt, and Cassie stood, her face flushed.

Alex, meanwhile, walked over to the bar and retrieved the remote for the sound system, pressing play. The Vangelis Bladerunner soundtrack began playing, echoing around the bar and upstairs, too. A good choice.

He dropped the remote back down on the bar and came back to us, at which Matt handed Cassie off to him. He took her by the arm again as Matt collected his case, and led her over to the wide staircase that led rather grandly up through the building. Matt, meanwhile was fishing around for something in his case before zipping it closed.

"You should have that," he said, tossing something small over to me, "use it at will."

I caught it, rather deftly in my humble opinion, and saw that it was a remote control. Being a bit slow occasionally I wondered for a second before realising it was for the butt-plug, which obviously vibrated. Nice, I thought, though I held back from using it right then and there.

I brought up the rear as we all climbed the stairs. Four steps ahead of me was Cassie, and it was hard not to watch her arse, and the base of the black butt-plug peeping out from between her cheeks as she walked. As we passed the first floor, I glanced at the playroom there, and to anyone out of the loop it simply looked like a somewhat modernist living area, with steel and leather and vinyl furniture, all in grey and lilac. Tasteful, if your taste is different to mine.

I found out later that the other side of the floor was occupied by bathrooms and a wet room, and a sauna, and also an examination room for those with a medical fetish. I couldn't imagine it, personally, but then, there are more things on heaven and earth...

We went up to the next floor, the top apart from the attic. Alex took Cassie to one side through a door and immediately told her to kneel just inside the doorway. I followed with Matt, who smiled the instant we entered the room.

"See what I mean," he said, "classic."

The room was indeed a classic of its type, a kind of faux Victorian drawing-room-cum-boudoir with added 'furniture', but big. I found a seat on a plush chaise while Matt put his case on a side table and opened it, conferring with Alex in low tones as they looked through the contents. I guessed they were taking their time on purpose, thus giving Cassie time to look around. And wonder what was going to happen next.

I looked around, too. It was all heavy wood and blackened iron and crimson furnishings, with up-lighters in wall brackets. There was a large four-poster bed, and looking more closely I could see heavy eye hooks at the corners and on the posts. There was also the obligatory St Andrew's cross, and a padded arch that stood at about waist height, and a chair with more eye hooks at various points but which seemed to have no seat as such, but rather two flat sections where the subject could sit. Studying it, it seemed that the seat halves and front legs of the chair were integral, and a subject would sit on it and have the seat halves spread open to the desired angle.

There were two other noticeable pieces of furniture, a frame like a very broad ladder that stood at an angle from the floor to the angle between the top of the wall and the high ceiling, and a table. The table was very interesting, with a bed frame type affair all along one edge, and at the corners opposite stood iron posts. I could imagine Cassie laid on that table and secured.

I glanced at her, and from where I was sitting I could see her in profile. She looked composed, but I suspected she wasn't. It was then I remembered the remote that I was carrying. I looked at it properly and saw it had three buttons -- a mode selector in the middle and plus/minus buttons on either side. I pressed the mode selector and was rewarded by hearing Cassie's slight intake of breath.

Looking back at her, I pressed the plus button once, and saw her glance over at Alex and Matt, still in discussion. It was then I realised that she hadn't heard, or hadn't seen Matt throw me the remote. She didn't know I had it and probably thought they did. That could be fun.

Alex and Matt seemed to have concluded their conference, and they both turned to look at Cassie. She tensed, beautifully, her tits lifting a little and standing proud. I wondered for a moment whether, even at this late stage, she would call a halt, but she simply stood when Matt told her to get up. Then Alex took hold of her arm again, but this time he wasn't so gentle as he pulled her over to the leaning ladder-like frame I'd previously noted.

"Legs apart," he said, as he pushed her against it, her face to the wall.

I now saw that there were pairs of joined cuffs on the floor by the side of the frame, soft ones that could be buckled to the subject. I turned off the vibrating butt-plug, and I don't think Cassie really noticed, her attention focussed on Matt and Alex as they attached the cuffs to the frame, and then lifted her arms above her head. Her wrists were secured to either side of the frame, and I could see her breathing was getting light and fast -- this really was getting to her.

Next, the guys fastened her ankles to the frame in the same way and she was spreadeagled, if basically standing. This was something I knew Cassie loved, to be restrained, open.

"Do you want us to tell you what will happen next, slut?" said Alex, his mouth by her ear.

"Yes, sir. Please."

"Tough!" said Alex with a smile.

One of the features of the frame was that the ceiling was high enough, and the frame at the right angle, to allow someone to stand comfortably between the frame and the wall. Matt now did so, and turned to face Cassie, looking her up and down. The horizontal bars were quite widely spread, and there was plenty of space for her tits to fit between them.

Matt examined Cassie, raising his hands to her tits after a second, and then rubbing his thumbs over her nipples. She breathed in sharply again as her nipples hardened, and Matt smiled.

Alex, meanwhile, had stepped back to admire Cassie, cuffed to the frame. He took in the sight, and I could see his expression was... possessive? Perhaps, or perhaps predatory. Maybe something in between. And then he went back to the case and pulled out a riding crop.

A slap and a gasp drew my attention back to Matt and Cassie, and I saw him slap her breast for, I presumed, a second time.

"Do you like that?" Matt said, standing close to Cassie.

"Yes, sir," she said softly.

"I thought you would," said Matt, "anyway, there's one more rule we haven't told you yet. If you want to come you have to ask permission. Is that clear?"

"Yes, sir." And the colour went to Cassie's cheeks.

Matt started to unbutton his shirt, and Alex stood waiting behind Cassie, a smirk on his face as he let her look at Matt. And if I was a girl, hell, I'd look at him, too! He'd been working out more since the last time I saw him, and whilst he wasn't over-muscled at all, he was really toned now. I knew Cassie would like that, and I knew she would like the tribal tattoo that spread over his shoulder and down his upper arm. He dropped his shirt casually to the floor, and If I had to guess, she was hoping he'd lose the trousers, too. But he didn't, not then.

He stepped back to her, so close their faces were almost touching, then reached his hand up and bushed his fingertips across her cheek.

"Are you wet?"

"Yes, sir," Cassie answered, her voice still soft. Whether it turned Alex and Matt on, I don't know, but it got to me and I had to shift in my seat.

"Yeah, I'm going to need to check that," said Matt, grinning, and he dropped his hand down between her legs and began investigating her pussy. At the first touch Cassie had her lip held in her teeth and when he slid a finger to the knuckle into her, she let out a loud gasp.

"In front of your boyfriend, too," said Alex, "you really are a slut, aren't you?"

"Yes, sir," Cassie said a little louder, and then she yelped as Alex brought the riding crop down, hard on her arse.

"Thank you, sir," said Cassie through her gasps, and now Matt began to finger-fuck her more firmly.

"You want our cocks, don't you?" he said.

"Yes, sir," Cassie gulped, and I could see that she was finding it harder to focus.

And then she yelped again as Alex spanked her other cheek with the crop. I took a huge gulp of my drink at this, losing myself almost as much as Cassie was. My only regret was it wasn't being filmed, but then had it been, it wouldn't have been nearly as good as being there.

"You're going to have to earn that, slut," said Matt, and he pushed a second finger into her. Even sitting where I was, I thought I could hear the squelch of his fingers in her as he fucked her faster. It was probably only wishful thinking, but I went with it.

Alex spanked her again with the crop, and she groaned, and now I could see sweat breaking out across her skin.

"Have you been keeping count?" said Alex.

"No, sir. Sorry, sir," said Cassie.

"That's three," said Alex, and he continued spanking her with the crop, and now she kept count between her gasps as Matt slid his fingers deeper and deeper, in and out of her.

When she got to eight I remembered the remote again, and as I turned on the plug her voice raised an octave. Nine, ten, and here I think she expected Alex to stop, but I knew him better than that.

"Eleven!"

"Twelve! Please, sir, may I come?" said Cassie, and her voice was getting urgent.

"Thirteen!"

"No," said Matt finally, and Cassie groaned again, now in a disappointment that sounded almost like pain as he pulled his fingers away from her.

I fumbled with the remote, trying to turn off the plug and rob her of the sensations so she really couldn't come, but it took me a moment and I think that was another happy accident. Looking at her face while the plug was still throbbing in her anus, I could see she was struggling to repress a wave of pleasure and not break a rule. And then I managed to turn it off.

"Fourteen!" gasped Cassie, and for the first time in a minute or so, I actually heard the crop make contact with her reddened skin, so intent had I been on her reactions.

Alex lowered the crop, but of course Cassie couldn't see that. What she was focussed on though, probably, was Matt's fingers. Her held them up to her lips and pushed him into her mouth, making her taste herself. She breathed heavily, still close to an orgasm and now further stimulated. I knew she liked it, but what I wanted to see even more was Cassie tasting another woman on some stranger's fingers. That was for another time, of course.

Then Matt took his fingers away and both the men walked back over to Matt's case, Alex retrieving his shirt as he went. Cassie was left to her thoughts, and I watched her as her breathing slowly subsided. Alex and Matt, meanwhile, removed their clothes and folded them.

Looking over at them I smiled, anticipating Cassie's reaction -- Matt certainly had nothing to be ashamed of between his legs, but Alex was sporting an unexpectedly large weapon (nine inches, for a guess), with girth and a slight curve to it, too. I was in the wrong place, unfortunately, to be able to properly see her reaction when she saw Alex, but I amused myself thinking of her expression.

It was Alex who walked around in front of Cassie when they returned, still with his crop and with something I couldn't see clasped in his other hand. Matt stood behind Cassie this time, a flogger in his hand and a greedy expression on his face.

While Matt looked over Cassie, Alex brought the crop up to her tits, letting the keeper slide over her nipples. I could just see that she had a little tremble, probably waiting for Alex to bring the crop down on her nipples. He took his time, though, as they both had so far -- there was no need to rush, so he caressed her for long, long moments before suddenly smacking the crop against her nipple.

Cassie jolted and cried out, but in another moment Alex had his lips enveloping her nipple, his tongue flicking at her, and she subsided with a gasp. He straightened up and started trailing the crop around Cassie's other nipple.

"Please, sir..." she whispered, but before she could clarify -- yes, or no -- he cracked the crop against her again, and again she cried out before he took her nipple between his lips.

"Open your mouth," said Alex, and once she did, he made her grip the crop between her teeth. Then, rather dramatically, he let the other thing dangle from his hand, and I could see he had a pair of clamps joined by a thin chain. Cassie couldn't say much about it now, but perhaps she didn't want to, with Alex running his tongue over her nipples, and Matt now pressing himself against her back. I wondered if she could feel his stiffening cock sandwiched between them.

Alex took the first clamp and attached it to Cassie's nipple, and I could hear another intake of breath. I remembered her telling me that she didn't understand it, but the pain made her wet, and I could see she was reaching another level. Soon, if they took the crop from her mouth, I was sure she'd be begging them to fuck her.

Once Alex had put the other clamp on Cassie he stepped back and went out of the room, leaving her to Matt for the time being. He had been using his free hand to caress her back, and let it drop to her arse. Now, it seemed he remembered the flogger in his hand. He went back and let swing, and there was the sound of it moving through the air. It connected with her cheeks, already a little pink from Alex, and she let out a muffled cry as she made sure to keep the crop in her mouth.

Matt whipped her with some skill, during which Alex returned with a couple of towels which I guessed he got from a bathroom across the landing. He sat and watched as Matt continued, Cassie's skin getting pinker, and her cries becoming a little stronger. I don't know how many strokes her gave her, but he suddenly stopped and pressed himself against her back again, and I saw that he had swapped the flogger around in his hand. And now he rubbed the handle along her cunt, and from her reaction, he hit the right spot.

He was slow, teasing her, and she was moaning, and then he suddenly turned the flogger around again and brought it up, hard, between her legs, whipping her cunt. Cassie yelped aloud, and it took an effort for her to keep the crop in her mouth. Matt whipped her cunt again, instantly following up by going close to her again and caressing her with the handle of the flogger once more.

We watched as he worked on her, and he expertly brought her to the edge, and then kept her there. She was trembling, her chest heaving, and her breathing was fast. Matt slowed down when he sensed she might come, and then took her right back to the edge again, and we heard a muffled, "ples, sr, my I cm?" from Cassie.

At which Matt stopped completely, dropping the flogger and walking over to Alex and me. Cassie groaned again in disappointment. It was becoming a habit.

"I think it's time we had a bit of fun, don't you?" said Alex, and Matt nodded, grabbing one of the towels and wiping himself down. But they left her there for the next few minutes, casually looking at her as her breathing slowed.

After what might have been five minutes they went back to her and, without a word spoken, undid her restraints and let her shake out her wrists and ankles. Alex then pushed her back against the frame whilst Matt went to his case. Alex let his hands roam over her body, investigating her, and finally moving to the chain between her nipple clamps. He smiled and took the crop from her mouth, dropping it to one side, and then replaced it with chain.

He surprised her with his next move, and to be honest, he surprised me, too. So far Alex had been rather soft, all things considered, but now he grabbed her by the hair and pulled her roughly across the room. Cassie cried out, bent double as she tried to keep up with his long strides, and as she cried the chain fell, the dropped chain now swinging as her tits swayed a little, too.

"Stand straight," he ordered, stopping. She obeyed, and immediately put her hands behind her back. He took the chain and pulled it, hard, and she cried out again, at which he put it back in her mouth.

After that, he took her by her hair again and pulled her over to the end of the four-poster bed, making her kneel at one corner, her back to the post. Matt, meanwhile, had taken a pair of handcuffs from his case. He walked over and put the handcuffs on her, her arms in front of her, and then lifted then above her head to one of the eye hooks, and he slipped one of the links in the chain on to it, securing her.

I loved the way she looked, kneeling again with her legs spread, but now with her arms up and still with the chain in her mouth and her tits lifted up a little in consequence. She was looking at Alex, or from her position more probably Alex's cock, and if I knew my girlfriend, she really wanted that cock by now.

"You want to suck me, slut?" said Alex, none too gently. Cassie nodded.

He moved closer and ordered her to open her mouth, and from my angle all I could now see was his arse and the back of his thighs. I glanced around and changed position, coming and leaning on the other post at the end of the bed, and by now Cassie was taking the head of his cock in her mouth. Alex grunted, and I suspected that he was going to enjoy the next few minutes, Cassie priding herself (with good cause) on her oral skills.

He eased his cock further into her mouth and then wound his fingers into her hair on each side of her head. I doubted she would be able to take all of him, but she looked like she was going to try, and then Matt came and knelt by her, moving his hand down between her legs to explore her pussy.

It occurred to me that I hadn't turned the butt-plug on for a while, so I found it in my pocket and pressed the plus button. Although her gasps were muffled, we could hear them, and they grew stronger -- perhaps it was Matt fingering her, or her submissive enjoyment of Alex getting half his cock in her mouth, or perhaps it was the buzzing of the plug. I suspected it was the combination.

Matt looked my way and motioned upwards with his eyes, a clear signal to up the strength on her butt-plug. I nodded and press the plus button twice more, then a third time for luck, and Cassie was now moaning, and giving Alex the best that she could. He fucked her mouth in return, and it was clear she was losing herself again.

"My turn," said Matt and took over from Alex, who stepped back then went to Matt's case, looking for something.

Cassie eagerly took Matt in her mouth, and in comparison to Alex she could take all of him, nearly. Matt, of course, was going to be sure.

He had her lick his shaft, then he pushed his head between her lips and she was greedy. As soon as Matt sensed that he pulled back, teasing her with his cock and making her chase him with her mouth. Then he gripped her hair and pulled her head back, holding her firmly.

"Open your mouth, wide," he said, and she obeyed.

He paused for a moment and then pushed his cock deep into her mouth. She gagged but he held her, not letting her move, and holding his other hand out to Alex. Guessing what Matt wanted, Alex retrieved the riding crop and handed it to him. Matt eased his cock back out of Cassie's mouth, letting her gasp down some breaths, and as she recovered he held the crop by the business end and slipped the handle up between the chain and her sternum.

"All of it this time, slut," said Matt, pulling the crop away from her and stretching the chain. Seeing the clamps pull at her nipples and hearing her react, well -- I still couldn't understand her attraction to it, but she looked amazing.

Matt pushed his cock into her mouth again, now even deeper, and Cassie did her best, pulling back a little but only so she could move forward and take even more of his shaft. Matt lifted the crop even more and a muffled whimper came from Cassie before she took his last inch, and he let his head fall back as he enjoyed feeling his cock enveloped. After which he pulled back and lowered the crop, though that wasn't the end for her -- he demanded more and for minutes she licked and sucked his head, wrapping her lips over him and making him gasp, now.

"I bet everyone thinks you're respectable, don't they, slut?" said Matt as he finally stepped away from Cassie. At the same time, I turned off the butt-plug, wondering how much charge it had -- I would save some more for later.

"Yes, sir," she said after a moment to catch her breath.

Alex knelt next Cassie as Matt walked away, taking hold of the chain between the nipple clamps. He pulled and she sucked in a breath.

"Do you like that, slut?"

"Yes, sir. Thank you, sir."

"Does it make you want to fuck?"

He pulled the chain a little harder, stretching her tits out towards him. Instead of a gasp she let out an audible, "ow!" Alex repeated his question.

"Yes, sir, please," said Cassie, and there was an edge to her voice.

Alex continued to tease Cassie with the chain, but I looked around to find Matt. He was standing by the table I had noted earlier, and I could see he was preparing it. There were two posts with hooks standing at opposite corners, and he had attached a soft cuff to the top of each post with what looked like carabiners.

On the table top there was already a towel, which I guessed Matt had put there. There was a large soft pad resting against the frame running along the length of the back of table, and there were already cuffs prepared there, too. It looked like Cassie was going to get a pounding there, and I licked my lips -- was this getting to be too much for me? I had seen her fuck other people, and she'd seen me do the same, but I hadn't seen anything this intense. I stood up and slid out of the room for some air.

I spent a minute pacing on the landing, analysing my own feelings. I think it was her last expression of pain that had got to me... But, on the other hand, she told them she enjoyed it, and she had her safe word. I mentally slapped myself for thinking her weak. She was strong, and I was seeing her strength. It occurred to me, too, that she hadn't looked at me once since we'd climbed the stairs, and that meant she didn't need my approval any more, another sign of strength. And then I thought about how hot she looked in their power, spread and submissive... and I was standing out on the landing missing it!

I slipped back into the room to see they had already taken Cassie to the table. She was sitting on it and just in the act of lying back so her head and shoulders were supported by the pad, her legs dangling from below the knee. I moved closer, finding a chair and moving it so I hoped I would see all the action to come. Alex, standing between her legs, clicked his fingers and Cassie presented her ankle to him.

He was firm as he lifted her leg, and she let out the cutest little gasp, and then he buckled the cuff around her ankle. Matt, meanwhile, was cuffing Cassie's wrists to the frame, and when Alex secured her other ankle she was wonderful to look at, her legs up and spread and her cunt exposed.

Matt leant over her and took first one, then the other nipple clamp off her. Cassie sucked in a painful breath as each nipple expanded again, and Matt chuckled. Then, being the bastard that he was, he flicked each nipple, hard. Cassie gave a pained moaned at that, and her thighs trembled a little as she looked at him with increased desire.

"Do you want us to fuck you, slut?" said Matt, his tone quite harsh.

"Ask us," said Alex.

"Please fuck me, sir," said Cassie to Matt, which of course wasn't convincing enough the first time, and with Alex scraping his fingernails quite gently down the back of her thighs, she had to ask again. This time, with Alex's assistance, she was definitely believable, with a hungry edge to her voice.

"You want us to fuck this pussy?" said Alex, his fingers now brushing over her arse and converging on her labia.

"Please, sir!" And Cassie sounded even more definite the third time.

Suddenly he spread her, roughly. She moaned.

"This dirty pussy? How many men have fucked it already? Twenty? Thirty? Forty?"

"I don't know, sir."

"Too many to count, eh?" And then Alex took hold of the base of the butt-plug. He eased it out of her until it reached its widest point, and Cassie tried not to show how much she liked it.

"What about here? How many cocks have you had here, slut?"

I knew the answer, but I wondered if Cassie would tell him something so intimate.

"Four, sir."

Alex smiled and slid the plug back into her as Matt climbed onto the table and knelt next to her, softly stroking his cock as she watched, waiting for him to make her suck him again.

"Do you like us treating you like a slut?" said Alex.

"I love it, sir," said Cassie, not taking her eyes from Matt.

There was a brief pause, and then Matt took her hair firmly in his hand and ordered her to open her mouth, pulling her to him. In a moment his cock was in her mouth and I could hear her trying to please him. Alex went and got the crop again as this was happening, coming back and going straight for her pussy.

With his free hand he spread her labia again, this time wider, and I had to shift in my seat again as I looked at her beautiful soft, pink flesh. Then, he spanked her pussy with the crop, and she jolted, her expression of pleasured pain muffled.

"So wet," said Alex, this time to himself, and he spanked her again, "dirty slut."

Matt climbed off the table, his cock hard and horizontal. He went straight for his case and pulled out a condom, ripping the pack open and rolling it down over his cock. He tapped Alex on the shoulder, who stepped aside for him, and I caught a glimpse of Cassie's expression as she saw Matt ready to slide into her hole. Of all the things that turned me on about that afternoon, that look on her face at that moment -- a little hungry, a little nervous -- is something that I remember with pleasure.

Surprisingly, Matt didn't tease Cassie, instead pushing his cock into her immediately. He wasn't too hard, but he was relentless, slowly sinking further and opening her up as she moaned, her pleasure evident as she gulped down a huge breath. Once he was sunk to his balls in her he stopped, and finally gave her a moment to become used to him.

"Mmm..." said Matt, "she's quite tight, actually. Aren't you, slut?"

This time Cassie didn't answer, as Matt quickly pulled back then sank his cock into her again, harder this time. Cassie whimpered, and we could hear that she was deeply aroused, her cunt flooding. I could testify that she got very wet, and there were times we would have to change the soaking bed sheet, often in the early hours.

Alex stood to the side, watching and slowly stroking his cock, and looking at him I smiled and shook my head: damn, but he was sporting a people pleaser, and I couldn't wait to see him stretch Cassie's holes. Whether she was anticipating him replacing Matt I couldn't tell, but as Matt began fucking her faster and harder there was no doubt she was enjoying it, her gasps getting louder and being replaced by moans. It was time, I decided, to turn on the butt-plug again...

Cassie's moans got louder, and she looked squarely at Matt and began asking him to fuck her harder, please, sir. Matt, of course, granted her wish, gripping her thighs and pounding her cunt and watching her tits sway. Then he reached for her nipples and pulled and twisted them, her moans rising in volume again as she gasped out a 'thank you' between thrusts.

Alex went over to Matt's case and fished about, pulling out a condom. He rolled the latex over his cock and tapped Matt on the shoulder, and with not a little regret Matt eased back out of Cassie. She, for her part, looked at Alex's sheathed weapon, and it was the moment of truth...

He paused, building her anticipation, before he pushed his glans into her, stretching her. He stopped to listen to her ragged breathing, and in truth everyone was focussed on this, even Matt who was halfway through pulling his condom off. And then he plunged into her, and it was as if his cock actually forced her moan out of her.

"It's so big, sir," she gasped, stating the obvious, but Alex simply ignored her, easing back and thrusting again. I, for my part, upped the power on the plug.

It seemed clear, as Alex began fucking her harder, taking her with long, smooth thrusts, that we were heading for some kind of conclusion -- if they let Cassie come, that is. She was moaning with every thrust, and Alex's skin was slapping against hers. Matt, now he had rid himself of his condom, climbed back on the table and knelt by Cassie, and it seemed he wanted something, too. He grabbed her by the hair and yanked her over to him, feeding her his cock and muffling her moans.

I don't know how much longer it went on, but it seemed pretty quick. I could see she was about to orgasm, with her thighs beginning to tremble, and it seemed that she wanted to try to ask for permission. It was clear the guys could see what condition she was in, but they didn't let up, and I suspected they wanted her to break their rule. I pressed the plus button on the remote control a final time.

Cassie began writhing, and I saw her try, and fail pitifully, to hold back. And then she was coming, gagging on Matt's cock and her cunt spasming around Alex's. Her legs and her arse shook and she squealed, and then Matt pulled his cock out of her mouth and he was close, too.

A second wave went through Cassie, and she heaved, moaning and gasping as a blush spread across her chest and Alex continued to pound into her. Matt, meanwhile, stroked his shaft and then his head fell back as, sweaty and red-faced, he came, aiming his cock at her torso. His first spurt missed her, shooting cum above her and down onto the floor, but his second, and third, and then last, all landed on her neck, and down over her sternum, dribbling down between her tits.

A last contraction hit Cassie, and she clenched her eyes shut and her head fell to one side. It looked like that might be enough for her, and I was impressed, again, with Alex for picking up the sign. I turned off the plug and he slowed down and then stopped, only easing out of her, giving her pussy a moment to bid him goodbye, as Matt slid off the table and stood, breathing heavily. Cassie's breathing wasn't the calmest, either, but she tried to collect herself.

"I'm sorry, sir," she said to Alex, "I tried not to come..."

Alex, however, didn't say a word. Instead, he began undoing her restraints, and Matt, now he had his breath back, began collecting his bits and pieces together.

"Would you like me to take that out?" Alex said to her, meaning the butt-plug. Cassie nodded and gave him a wan smile, and he eased it out and put it to one side -- though it looked like she felt a last ripple as he did so.

"Do you feel ok?" he asked as he helped her to sit up. She nodded again.

"Did we go too far at all?" She shook her head and gave him another smile.

"Ok. There's a bathroom over the landing. Have a comfort break and clean yourself up..."

Cassie slid off the table and began to walk a trifle unsteadily to the door.

"But.." said Alex, stopping her momentarily, "don't clean that cum off. I want to see that on you when you come back."

"Yes, sir."

As Cassie left, Alex pulled off his condom and tossed it in a small bin near the bed, and then he took a towel and wiped himself down before grabbing his clothes.

"Come on," he said to me, "I could do with something more to drink. And we need some more music."

To be honest, I hadn't even noticed that the soundtrack had finished, but I followed him downstairs, leaving Cassie in Matt's care.

We were chatting by the time Matt came down ten minutes later. He had a towel wrapped around his waist, as did Alex, and was carrying his case. There was, however, no sign of Cassie.

"She's fine," he smiled, "I left her thinking about what just happened. And what might happen next."

"I knew she was into this stuff, a bit, but I didn't know she was such a submissive," I said.

"She's not," said Alex, "she's a bottom. Most people don't know there's a difference. It's like, would she live the lifestyle twenty-four-seven? Spend a month naked if you told her to? Sleep on the floor while you slept on the bed?"

I shook my head.

"Then what she wants is sexual, not a permanent lifestyle. That makes her a bottom, and there's nothing wrong with that. Just use submissive as an adjective, not a noun."

"Yeah," said Matt as he got himself a drink, "and does she want this kind of sex from you all the time?"

"No," I said, "just sometimes. But I'm not really cut out for it. I can do a bit, but I think this stuff today is what she's after when she's in the mood."

"And what did you think of it?" said Alex.

"Honestly? I thought it was pretty fucking hot. She looked... fantastic. And I loved how hard she came, and the sounds she was making when you wouldn't let her come."

Alex was nodding along, and then he chimed in, "ok, well perhaps you've got some ideas, and if you feel like giving her something sometimes, just remember to keep checking in with her that it's going ok. But also, make sure to get your own pleasure out of it. Don't just make it about her."

"And," said Matt, "there's something else you might find. It's pretty common that once someone's had a first session like this, they start getting greedy."

"Yep," said Alex, "a known phenomenon. Of course, if she wants to do some more stuff and you're cool with it, then great, but keep an eye on her that she's isn't trying to experience everything she can at a hundred miles an hour."

Then Alex changed the subject and we talked for another ten minutes or so, long enough for me to almost forget why were there.

"Should we start again?" said Matt, and Alex nodded.

"Let's go and get her," he said, and he reached for his case full of implements...

* * *

We climbed the stairs back to the top floor unhurriedly, Alex having put on the Solaris soundtrack. I was first through the door into the classic playroom, and what I saw arrested me. It was nothing particularly special to the cognoscenti, I suppose, but it interested me. Matt had placed a plain chair into the middle of the room, and Cassie was sitting on it, still naked but now blindfolded, her arms tied to the back of the chair, and her ankles to the chair legs. And around her neck she was now wearing a black collar, from which hung a steel ring.

Matt explained later that the point of the blindfold was to heighten Cassie's other senses, and mess with her perception of time, whilst leaving her naked meant she knew we would see her this way when we came for her and it would heighten her perception of vulnerability. All in all, it was very artful, and once more I liked what I saw. For a moment I was even tempted to join in, but I realised it would unbalance Alex and Matt's dynamic, and probably spoil Cassie's fun.

Alex and Matt went up to Cassie as I leant on the doorpost. She must have heard us coming up the stairs, but I'm not so sure she realised how close Alex and Matt really were to her, they moving quietly in bare feet. Alex's soft touch, just his fingertips on her forearm, seemed to make her jump a little.

"We're going to start again. Are you ready?" said Alex.

"Yes, sir," said Cassie, and her voice was a little firmer now, more definite.

"You broke a rule earlier, slut," he went on.

"Sir?"

"We told you not to come without permission," said Matt, leaning down next to her ear.

"But I couldn't ask..." said Cassie, and I could hear the beginnings of indignation.

Matt simply reached out and took Cassie's nipple, twisting and pulling it, and she finished her complaint with an, "ouch!"

"Not without permission," said Matt, pulling at her nipple for a long three seconds more before letting go, and Cassie's breathing was light and fast as she withstood the pain.

"What do you think we should do when a slut breaks a rule?" said Alex.

"She should be punished, sir," said Cassie, and I could see her shift a little, perhaps betraying some excited anticipation.

Alex and Matt then spent a quick minute untying Cassie, and I could see Matt had tied her with quick release knots. Alex then pulled some handcuffs and a chain leash from his case, and Matt ordered Cassie to stand.

With Alex and Matt standing close on either side of her, I wondered if Cassie could feel their heat, their presence. One glimpse of her face, her lips parted, confirmed it -- she was getting horny, perhaps feeling her nakedness, not knowing Alex and Matt hadn't dressed. Matt started to touch her back, softly running his fingertips over her shoulder blades and then down. I saw her shiver then relax, it being one of the things she loved most. I, however, suspected that the softness was merely a prelude, and sure enough, I saw Alex hand Matt the handcuffs.

Alex stepped in front of Cassie holding the thin chain leash, and he clipped one end to the steel ring on her collar, and let the other end drop. The leash had a leather loop at the end which bounced off Cassie's legs at mid-thigh, and I'm sure she thought Alex would take hold of the leash and lead her to their destination. Au contraire...

If Cassie didn't know that they were going to do next, well, neither did I, but I watched fascinated. Alex and Matt moved expertly, Matt folding Cassie's arms behind her back and clicking a handcuff around her wrist as Alex fed the end of the leash between her legs. Matt then took the end of the leash and pulled it up, then slipped the other cuff through the loop, and clicked it around Cassie's other wrist. It only took a few seconds and she had the chain secured firmly against her pussy.

Alex then fetched another leash and also secured that against the steel ring on Cassie's collar and this, it seemed, was actually to be used to lead her. This was borne out when Matt took hold of the leash and began to take her out of the room whilst Alex collected his case. When we got to the stairs it felt like the first time I needed to intervene, but Matt was super-careful getting my blindfolded girlfriend downstairs, so much so that after the first flight I began focussing more on the chain between her legs than my fear that she would fall.

I asked Carrie about it later, curious, and she said it she was a little scared at first, but it only took a moment or two before the feel of the chain pressing against her pussy turned her on. And then she felt that with every step she took she was soaking the chain more, so that by the time we stopped she thought she might even come again. So, it was nice, then.

Where we stopped was all the way down in the basement, the fake prison, and again it struck me how well the place was done. The stairs down from the bar ended in the middle of the basement, where Matt removed Cassie's blindfold, and we both took it all in at the same time. Some real thought had been put into it -- we were standing in a small open area with a breeze block wall to one side of us (soon to be revealed as a partition), and an expanse of concrete flooring and some cells to the other, all lit by naked bulbs.

The cells were in the American style, with bars instead of walls. The smaller cell had a pair of bunks, while the larger had two old-fashioned single beds with iron bed frames, and bare mattresses with no pillows or sheets or blankets. There was also a shower and toilet room I could see, with a couple of stalls and a shower room, all without any privacy, naturally, and everything was in a dirty shade of grey. I'm sure to an actual American prison guard from the 1970s it would seem like an obvious sham, but from where I was looking it seemed pretty realistic.

Alex and Matt weren't going to play with Cassie here, though. Instead, Alex led her to the end of the breeze block wall where there was an open doorway. On the other side of the wall was a narrow passageway leading back, and there were more cells, now with walls made with more breeze blocks. There were four doorways, and Cassie was taken quickly past the first two. The first had another single bed, and nothing else, whilst the second just had a chain hanging down in the middle of the room, ending in manacles.

Alex stopped Cassie at the third cell and took her in. In the middle of the cell was a wooden post, slightly taller than me. At the top of the post were iron rings, whilst about a third of the way down was a strange wooden projection, a foot long and angled downwards. At the base of the post there were more iron rings, and others were set into the concrete floor. I looked quizzically at Matt.

"It's a whipping post," said Matt, stepping up to Cassie and grabbing her by the hair, pulling her head back a little, "the slut needs to be punished, don't you?"

"Yes, sir," said Cassie, and there was lust in her voice.

"All in good time," said Alex, and he pushed her until her back was against one of the walls. I stood to one side, just outside the cell, trying to keep out of Cassie's eyeline so as not to compromise her suspension of disbelief.

Matt went up to Cassie and began to brush his hands over her, whilst Alex found a plain wooden chair from another cell and brought it in to rest his case on. He opened the case and pulled out a pair of nipple clamps and wandered back to Matt and Cassie. Matt, meanwhile, had let his hand drop down between Cassie's legs, and as she gasped and rubbed the chain against her pussy.

"Feel this," he said to Alex, "she's soaking wet again."

"Yeah," said Alex, "and look at her tits."

Matt nodded, smiling at the sight of Cassie's nipples standing hard, and the blush that spread across her cheeks as Alex pointed it out.

It was time for the new clamps, and Cassie had her bottom lip held tight between her teeth, and she sucked in a breath as Alex put the first one on her, and now I saw that each one had a tiny brass bell hanging from it. Cute.

"If we tell you to stand still," said Alex, "we won't want to hear these bells. Clear, slut?"

"Yes, sir."

Only then did Alex probe Cassie's slit, smiling as she closed her eyes and focused on the pleasure she was feeling. Her breathing was deepening, and when Matt pulled at a hard nipple she whimpered, the sound erotic.

"That's enough of that, slut," said Alex, "you're here to please us, not the other way around."

Matt finished with a sharp pull and twist of Cassie's nipple and when she let out an 'ouch' Alex pushed his fingers in her mouth.

"Clean them!"

Cassie obeyed, and then Alex put the second clamp on her other nipple whilst Matt unlocked her handcuffs and straightened her arms. Then they unclipped the leashes and tossed them aside, before pulling her over to the whipping post. It only took a few moments for them to secure her to the post, and I saw the purpose of the angled protrusion. It rested on her sternum, making her lean forward and turn her face to rest her cheek against the wood. Her wrists were attached to the rings with cuffs from Alex's case, and her ankles likewise to the rings set in the concrete floor. And so, she was presented, legs apart and arse pushed out, away from the post -- and a pretty sight she was, too, with her cunt on show, too.

Alex took a black paddle from his case and went up to Cassie, leaning in to her ear as he placed the paddle against her buttock, soothing it over her soft skin. She shivered, and I tried to hear what he was saying in her ear, but his tone was too low.

"Because I came, sir," said Cassie.

Alex said something more.

"Yes, sir, I loved it."

"Even though we told you not to?"

"Because you told me not to," said Cassie.

Alex waited no longer and brought the paddle down, hard, on Cassie's arse. Her yelp was loud, and her skin reddened quickly, and Alex followed up with more strokes of the paddle to both her cheeks. Before, both Matt and Alex had been slow and measured when they chastised Cassie, but now Alex was rapid, not giving her a chance to absorb a blow before another fell.

"I'm sorry, sir. Please, sir," said Cassie after a dozen or more cracks of the paddle, but Alex continued, and another half-a-dozen blows rained down with Cassie crying out for him to stop. I almost stepped in again, which would have been a mistake, but as I was making my mind up to do so, Alex just as suddenly stopped and tossed the paddle aside.

"Come on," said Alex to Matt, "I want to use her."

It didn't take long for them to untie Cassie from the post, and they pulled her quite roughly into the next cell, where the chain hung from the centre of the ceiling. The chain ran across the ceiling and down one wall to where it could be wound or unwound to adjust its height, and Alex lowered it whilst Matt bent Cassie at the waist in the centre of the room. Her arms were pulled behind her back and her wrists were fastened to the manacles and then Alex raised the chain a fraction, restraining her very effectively.

Matt walked around in front of Cassie, her lowered head at the same level as his cock, and as he tossed his towel aside he told her to suck him. She did so, enthusiastically, his hand gripping her hair and controlling her. I was watching Alex, though. He had brought his case in from the other room and now pulled out an anal dildo, one of the ones in clear plastic with a series of bulges getting fatter the closer they were to the base. He then took his bottle of lube, and gave Cassie's arsehole a healthy dollop, and of course she could guess there was going to be some anal play, but not the invasion to come.

Cassie whimpered with pleasure when she felt the lube, Matt taking the chance to go deeper in her mouth, and then she shuddered a little as Alex spread her cheeks apart. She stepped forward a little, trying to balance herself as Matt pulled her onto his cock, and Alex took that as her trying to pull away from him.

"Hold still," he commanded, and brought his hand down, slapping her red buttock. Cassie choked a little at that, wanting to moan but unable, and she turned a little to one side. Alex spanked her again, and then went back to his case at speed, and came back after a second with a belt.

I thought he was going to use it on her arse, but instead he wrapped around her hips and held both ends with a strong hand -- now she couldn't back away from him. The dildo was gripped in his other fist, and he pressed it against her poor, lubed arsehole, then pushed it into her.

Cassie moaned this time, eagerly, her thighs and buttocks trembling a little. Matt continued to fuck her mouth, not letting her gulp down the breaths she surely wanted, and Alex held the dildo firmly, pushing the first bead, then the second, and then the third into her, her voice rising in tone as each bead stretched her.

He eased it out of her until only the first bead remained, and then smoothly impaled her again. And so he fucked her, with long, slow, liquid thrusts, her arsehole tormented between pleasure and pain as she whimpered, her lips and tongue used as Matt directed.

"Swap," said Alex after some minutes, and he and Matt quickly changed places. Matt fucked her faster with the dildo, and she had more difficulty getting Alex's cock in her mouth. But for the guys, this was her problem, not theirs -- she was their toy now, and it was her job to please them.

Matt had enough of the dildo and pulled it free, Cassie squeaking in disappointment to feel it go. He grabbed a condom from the case and put it on, then positioned himself behind Cassie. I'm sure she thought, at the moment he grabbed her by the buttocks and spread them, that he was going to replace the toy with his cock, but he didn't, not right then...

Instead he rammed himself into her cunt, not caring overmuch to be gentle. Which is how he fucked her. He kept hold of her as he ploughed into her, over and over, his skin slapping against her arse, and now the bells on her nipple clamps began to jingle prettily. Alex took his cock from her mouth to let her gasp at Matt's thrusts before pushing back into her, and he did this again and again, and she thanked them when she could draw breath, but I knew this wasn't how it would end.

"We should shut you in here with a load of guys, and not let you out until they've all come," said Alex as he took his cock out of Cassie's mouth for the third or fourth time, "you'd beg for more, wouldn't you?"

"Oh fuck, yes!" she managed to gasp, before Alex pushed his cock back into her.

"You'd let them use all your dirty holes," said Alex, "and they'd be impatient."

And Cassie moaned, muffled by his shaft, her thighs trembling again. At this Matt and Alex exchanged glances and nodded.

"Let's get her on a bed," said Matt.

"Next cell," said Alex nodding, and in a moment they had freed her from the chain.

They straightened her up, and before she could really register what was happening, they rushed her into the cell with the single bed. Alex had grabbed his handcuffs and a condom, and whilst Matt pulled Cassie's hands behind her back and cuffed her again, Alex rolled on the latex. He sat on the bed, his cock standing proud, and he looked at her with a broad smile, knowing how much she wanted to fuck.

"Sit on my cock," he told her, and she stepped forward. Without her hands it wasn't so easy, and neither Alex nor Matt were inclined to help her -- if she really wanted it she'd manage. She straddled him, carefully, and he held his cock for her as she positioned herself, and then she sank down. She took a little of him at first, acclimatising herself to him, but he wanted more, right away.

With his free hand he grabbed her hip and pulled her down, his shaft stretching her and making her moan out loud, the sound echoing off the breeze blocks. Once she was sunk to the base on his cock he used both hands on her, holding her around the waist and lifting up then pulling her down, again and again. She couldn't stop moaning, her pussy wrapped around his fat shaft and she told me later, with evident pleasure, that she could really feel every inch.

And then came the highpoint, the conclusion Cassie hadn't expected. Alex shifted around on the bed, Cassie still impaled on his shaft, and he lay back as Matt got on the bed behind them and then pushed her forward to lie on Alex's chest. At this, Cassie looked straight over at me for the first time, her expression torn, but uppermost was a question: had I told them?

I nodded. Yes. Yes, I had. Cassie having a DP was something we had talked about for quite some time. She wanted it, and not just as a fantasy. It was something that was right there near the top of her list, but despite our visits to swinger clubs the moment had never been right -- either the people were wrong, or her mood was wrong, or we were just wrapped up in doing something else.

And now, unexpectedly and without a chance to reflect on it (or reconsider at the last moment), another of her desires was to be fulfilled. She looked a 'thank you' at me, an expression of lust and love and anticipation, and then she forgot me as Matt positioned himself behind her, his cock horizontal an inch away from her arse. He eased forward, her buttocks in his hands again, and spread, and this time her pussy was already full...

I'd never heard her make quite such a yell of ecstatic enjoyment, and she got louder as he slid slowly into her, little by little. And where before they had been joyously firm with her, now they slowed it down, easing her into the sensations as she swore at the top of her voice. Gone were the respectful 'sirs', and now she called them fucking bastards with the greatest affection until Matt had sunk to his balls in her, leaving her gasping.

They fucked her slowly at first, speeding up only when she asked them to. From the first moment it was clear she was going to come soon, and come hard, and when Matt grabbed the handcuffs and pulled her up, I could see that the line she was about to cross was gossamer thin. He spanked her with his other hand and Alex thrust up into her, relentlessly, and she continually told them to fuck her, to fuck her harder, to fuck her deeper, until suddenly she froze.

"PleasesirmayIcome!?" she managed as she grimaced, and Alex smiled and waited a heartbeat longer than was kind before he said yes.

She didn't lose control immediately -- that took another few seconds -- but when she did, she jolted and she shook and she fell forward on to Alex and he growled as she sunk her teeth into his shoulder, quite forgetting where she was or who he was. She jolted repeatedly, her hips pushing back and her holes devouring their cocks.

In the midst of it, Matt grunted and he stiffened, pushing harder into her as he came, too. After some seconds he grunted again and went limp, rolling off her and away, to lie on the bed with his back against the wall, breathing heavily with a happy grin on his face. Cassie, meanwhile, seemed still to be coming, surfing another wave as she shook and gulped down oxygen until her head spun.

Finally, Alex lifted her off him and pushed her to one side, and still she was trembling. He pulled off his condom and then grabbed her hair, pulling her off the side of the mattress and on to the floor, ordering her to kneel. He sat, and then controlled her firmly as he took her mouth, fucking her as the veins on his neck began to stand out, and his cheeks reddened.

And then he groaned, and pulled out his cock, gripping his shaft with one hand and her hair with the other, and he unloaded all over her face. The first spurt hit her cheek, and the next hit her chin, and then final ones went down her neck and over her chest. He breathed heavily and then flopped back, out of the way, letting her slump forward with her shoulders on the mattress and her face turned to the side, all of them spent.

Matt, having been the first to come, and having a duty of care, was also the first to gather himself. He slid off the bed and went to find the key for Cassie's handcuffs in Alex's case.

"I think that's about enough," he said quietly to me before going back into the cell. I pulled out my phone to check the time, and saw to my surprise that we had less than an hour left on the allotted time in the house. Time flies, and all that.

"I'll put the coffee machine on," I said, and he smiled as I turned to go upstairs, leaving them to clean themselves up.

"Bring her clothes down first," Matt called after me, which I did, and I watched them slowly check if she was ok, stroking her hair and soothing her as she gave them, and then me, a weak smile as she sat, cum-stained and sweaty.

Twenty minutes later she was sitting on my lap and smiling, her arm around my shoulders, her hair still a mess but otherwise dressed and respectable, as were the guys.

"You'll have to come over to ours for dinner tomorrow," she said.

"I'm not sure that's a great idea, Cas," said Matt.

"Yep," said Alex, "you might feel a bit worn out and sore tomorrow. Not in the mood to host. And you might want a bit of time to yourself."

"Ok," she said, "the day after tomorrow. I insist."

"Alright," said Matt, "deal. For tonight, though, we can amuse ourselves."

"And I can show you a bit of the city tomorrow," I said.

"Perhaps one of the clubs you go to," said Alex, "I mean, you've only watched all this today. You might want some of your own fun."

"Would you be ok with that?" I said to Cassie.

"Are you kidding?" she smiled, "after you set all this up, how could I say no?"

It seemed to be wins all around, and we casually finished off our coffees waiting for the owner of the house to come back and agree that we hadn't broken the place. After which we stepped out into the afternoon sunshine, four respectable professional types, going about their respectable business.

What with work and study and responsibilities and tiredness, it was another week before I could flop on the sofa with Cassie, some series or other playing on the screen. Neither of us were particularly enthralled, but it was nice to have her curled up against me. On a whim, I decided to raise the subject of her session with Alex and Matt.

"How do you feel about it now, looking back," I said. She considered.

"I think that, except with you, that's the most fun I've ever had with my clothes off," she said with a smile, and she let her hand run over my T-shirt, across my chest.

"It felt," and here she searched for the word, "liberating. They put me in the zone, and all I had to do was experience the moment. Well, you were there, you saw."

"Would you do it again?" I said, trying to be neutral -- I didn't want to influence her answer, to have her say 'yes' just to please me, or for that matter 'no', for the same reason.

"You know I've hardly been thinking about anything else all week, don't you?" she laughed.

"And?"

"And Alex and Matt were great, really. Fantastic. And I would like to do something more, absolutely, but maybe something a bit different."

"Like what?" I said, imagining that we would be heading to some clubs or something.

"I'd like a couple, I think," she said, looking away from me now, perhaps trying to avoid any disapproval I might have.

"You mean a couple who both dominate you?"

"Yes," she said, and after a pause, "I'd like that a lot."

I could feel that just the thought of it was making her thirst, and suddenly I couldn't help but wonder how soaking wet she was in that moment.

"You realise that's a big ask?" I said, and I hated to disappoint her, but I could guess she was after something pretty rare. I imagined that most couples were a dom and a sub, not a dom and a domme. Which just goes to show I'm not as knowledgeable as I like to think I am.

"Well, actually," she said, and she grabbed her phone, swiping and finding an app and opening it. A moment later she showed me her screen, with a couple smiling out at me. They both appeared to be in their early forties, conventionally ok looking, prosperous and healthy. I looked at Cassie quizzically.

"They're on the scene, and their bio says that they sometimes like to play with a submissive girl." Trust Cassie to have done her research first.

"You like the look of them?"

"Why not?" she said, "they're relatively local, and..."

"And the thought gets you horny?" Cassie nodded, and relaxed into me a little more, turning towards me and breathing in my ear. It was pretty clear I was about to get laid.

"Ok," I said, "I'm cool with it. If they're interested. I guess you'd want me there again."

"Well..." she said, "I'm not sure it's an option. And..."

"And you like the thrill of me sitting around the corner in a coffee shop or something, waiting for you in case you need me, but otherwise out of the proceedings?"

"Fuck! I love that you understand me so well," she said, gently teasing my neck with her fingertips.

"You realise I'm going to need a damn good reward, don't you?"

"Oh, of course darling," she breathed seductively in my ear, "anything you want."

"Ok," I said, as if it was only this that convinced me.

"There's one more thing, darling," she whispered, her fingers walking down my body. It was a near certainty I would agree.

"I'd be so grateful if you could contact them for me," she said, "at least at first."

"Me?" and she nodded, giving me a big grin as she sprang up and fetched me her laptop. She opened it and found the site, then found the couple's contact details.

"You write them a quick 'hello' email right now," she said, "and I'll go and wait for you in the bedroom. Don't be too long..."

With that she smiled and slid off the sofa again, this time treating me to the sight of her slinking off, a sultry glance over her shoulder sealing the deal. I sighed and looked at the screen -- I would give myself about four minutes to get something down, and then I'd be following her. I started to write...
