I'd gone with my friend Jodie to collect this self-powered exercise bike she'd seen an ad for. It was pretty far away from her home and she needed an extra set of arms. Her husband and my wife were both teachers who worked together, so neither one was available to help. But I loved Jodie, she and her husband were like family to us, and if she ever needed help, I was there.

It was a terraced house, reasonably big, but impossible to find parking - we'd have to lug the thing all the way down the road together. The door was this surprising pink colour, and the bell played a cheesy electric sample of Big Ben.

"Shall we pretend we're married?" she laughed. "Like, to be silly."

I scoffed, and rolled my eyes. "Fine, yeah." Whatever. Jodie's sense of humour was unbearably romcom-ish, but sometimes that could be a lot of fun. My friend had dressed the part in a green lycra getup for testing out this bike. She looked cute with her brown hair cut pixie-short. That was new. I wondered if maybe she wanted to test drive her new look by acting out a character. I'd worn my sweats, mainly anticipating a lot of carrying.

The door answered, a woman of about her height in a white blouse and tweed skirt with gigantic curls of black hair hanging past her shoulders and all around. "You're Jodie? Christine, hi. You're here for the bike, hi! Come in!"

"This is my husband, Liam" Jodie pushed me forward to shake her hand. She wore a lot of rings.

"Bike's this way."

"Hello!" A man's voice called from somewhere to the back of the ground floor, but we were already hurrying upstairs.

"Okay, this is it..." The bike itself was clearly untouched. One more bit of exercise equipment circulating around households who didn't want to commit to a gym and believed that more stuff would do the job.

"You want to try it?" The man's voice, coming up behind us. He looked about 15 years older than the rest of us - white hair, a handsome but neatly lined face, dress shirt tucked into jeans that were too short. Judging by the decor and the way they recycled gadgets and gear, I guessed they had easy disposable income. He looked like he had money, at least. "Ted."

"Hi, yeah, if that's alright?" Jodie clambered aboard and with a few turns, the contraption bleeped and came to life. She set the incline until I could see the resistance in her face, and I have to admit the rhythm of her movement was arousing to me.

"God, she's a sight, isn't she?" Ted murmured next to me. I smiled as politely as I could, but Jodie heard the remark and flashed us both a grin. "Liam's always checking me out." She arched her back a little more and accentuated the movement of her hips.

"Yeah, I suppose I am," I said, remembering to play along.

"Don't blame you," Ted said, still sotto voce, pointless since Jodie and Christine could clearly hear everything. "Magnificent body."

Jodie didn't turn that time, but I saw her smile, this time more inwardly, and keep pedalling. I knew it was time to get out of there.

"Shall we get this down to the car, then?"

"Yeah," Jodie remembered herself, and hopped off the bike. "How much did we say?"

"Aaaactually, do you know what..." Christine mused. "While you're here, do you want to take a look at some clothes I'm getting rid of? You can just take them with you if you see anything you like, I'll donate it otherwise." She rolled open a wardrobe that covered one wall - lots more blouses, skirts, big dangly trousers, sundresses. "It's everything over in this section..."

I waited while Jodie flipped through. I was as close with her as I was her husband, Tom - I knew very well he would hate to see the way Ted's stare followed her ass. He'd want me to do something and I wasn't doing much.

"Oh my god - yeah, this one, and... oh that's lovely..."

"Try them on." Ted almost made it sound like an order. "We'll clear out, come on."

The three of us went out to the hallway while Jodie undressed in private, sorting through Christine's wardrobe and trying on one thing after another. I was invited back down to the kitchen, where Christine put on the kettle. We should have been on our way out by now, and instead, we were hanging around for tea.

"I'll just be a moment..." Ted stepped briskly out of the room, and I heard him on the stairs.

"How long have you been married?" Shit. Jodie and I hadn't bothered to get a story straight. I suppose we could've just come clean, but I didn't want to make the situation any weirder. Which is why I probably shouldn't have started lying even harder.

"That's the funny thing actually - we had two weddings, an official one and an unofficial one, a couple of years apart, so depending on how you count it, it's 7, or..." higher or lower? Which number was she more likely to say? "5."

"We've been together for 15 years. You can tell there's a bit of an age gap, right?" I nodded. As if that was subtle. "Still, Ted's very good. He's always been very good."

"Babe? Liam? Can you tell me what you think of this dress?" I didn't have time to find out what "very good" meant, as Jodie called urgently from above. I darted into the hall and nearly ran into Ted coming the other way. "Sorry, sorry" and he bustled into the kitchen.

Jodie was standing in a dusk-blue gown dress whose straps wrapped round her neck and barely kept her breasts in place. I got a little worked up at seeing my friend like this, replaced immediately by guilt on remembering Tom, and my wife, Susan. The look on Jodie's face was, at best, complex.

"Oh, wow. You look stunning."

"Yeah thanks, great, but..." she flapped a hand beckoning me closer. "That guy Ted just fucking grabbed me."

"What?"

"Yeah, he like... came in and put a hand on my ass. So fucking casual, he was chatting away the whole time."

"Shit. Jodie, I..." I wanted to say I was sorry. But her eyes were wild.

"I think he was filming me, too." A little twitch at the corners of her mouth. "You know, while I was changing. I think he was filming through the door."

I tried my best to read her face. I wasn't yet ready to admit that my friend's wife was thrilled at having been groped like this. She looked magnificent in that dress, too. Up close, I could see her bare skin and the way the silk flowed over her. Behind her stood the exercise bike, still not dismantled, so many more clothes tossed over it. She was an image of elegance and mania. Everything out of order.

"Okay, so..." I collected my thoughts, and tried to ignore the stirring of my own cock in my sweats. "We need to pump the brakes here, right? Get changed, I'll stall them, we'll get this bike and get the fuck out of here."

Jodie nodded, reality checked. "Yeah, sure. Yes. That's right... do you think she knows?"

Before I could answer, Christine yelled from downstairs. "Come down, show us! What dress did you pick?"

Jodie had already heeded the request, dashing out in a blur of blue silk.

"Oh, YES." Christine was thrilled. "I hoped you'd try that one. Oh, god, it looks so nice with the short hair, too. Give us a whirl?" Jodie obliged, and even I couldn't help but drink in the sight of her body twisting in that dress. I heard Ted make the creepiest fucking noise, too, and in my revulsion I realised I was half hard and barely better than him. No, I was better. I came to my senses - I wasn't groping anyone.

"Your husband certainly likes it," Jodie said, sheepishly.

"So does yours." I tried to adjust my stance, hoping to hide my arousal. It wasn't the outfit for it. The thought occurred to me that I wasn't being instinctively protective as a husband would be - I was being nervous and non-judgemental, as a friend. I tried to imagine how I'd behave, were Susan in this situation, and then felt another punch of guilt to my stomach. I stretched an arm round Jodie and pulled her against me in what I hoped passed for casual affection, and her ass pressed up against my cock, which strained to meet it. Now Jodie knew. She flashed me a quick glance, and pressed back against it.

Ted and Christine were embraced too, looking Jodie up and down without reserve. Christine was swaying, biting her lip, her eyes shifting to flirt with me. Her blouse was undone, almost all the way to where it tucked in to her skirt. Had it always been so? There was so much more skin on show now. And Ted, I could see that he was harder than me, and in no way shy about it.

"Don't tell Tom," whispered Jodie, her ass shifting left and right over my hardening prick.

"Who's Tom?"

"Her, uh, brother."

"What an odd thing to say."

"Well, yeah." Quick change of subject. I think by this point I was craving Jodie and ever more curious about Christine. But the idea of this compound betrayal felt too big to deal with. I felt sick. I couldn't let this continue. "So, uh, let's get you changed back, and then we'll finish our transaction--"

"Wait wait wait! I know!" Christine waved a hand, her blouse flying open and exposing her right breast for a second. "Wait there, wait there..." she dashed back out of the room, thudding up the stairs. Ted followed for a brief moment, just enough to catch up with the two of us, sidling up next to Jodie and staring down at her.

"Gorgeous wife you have here. I expect you have to watch her around lecherous old men, hmm?"

"What, like you?" she swayed against my cock again. I dared not look down, but I think he had a hand stroking her belly.

"Like me, yes." The two of them shared a laugh. She might have been his already, then. She seemed altogether too pliant, and the way she was now grinding against me made it unambiguous that we would descend together. How was I blameless? I was wrestling with the cravings as much as I could. The shame of dashing my marriage for a secondhand purchase, it felt cheap and ugly. So far beneath me. And I was grinding back, pressing my erection into the split of her ass and drunk on the feeling of her pressing back, soft cheeks mashed against my sweats.

"How did you two meet, anyway?"

"Juggling lessons." She lied so softly, all of a sudden.

"Really?"

"Yeah," I panted, as the senior creep's hands searched my fake wife's borrowed dress. "Our, uh, eyes met during a partners exercise. Juggling... sticks."

"Bowling pins, babe." Her hand was definitely gliding up his back, now.

"Yeah, silly me. Bowling pins."

"Okay, come and check it out! Guys!" Christine's call broke the tension. I could feel myself, wet with precum. I knew I was going to do it - whatever it was - then. It was then that I started seeking it. Lying to myself. I imagined she was my wife. My wife whom I'd met while juggling bowling pins, fine. And we weren't cheating. We were just a spontaneous couple in love, letting something weird happen.

"Don't tell Susan" I hissed, as Ted led us to the stairs.

"His sister," Jodie explained.

We filed back into the bedroom, and there, next to the exercise bike, Christine stood proudly, grinning her handsome face off in Jodie's workout clothes.

"See? Get it? Your wife dressed like me, so--"

"Yeah, I see. Very good." I smiled, staring at her in those skintight clothes. Fuck, I wanted her now, and what's worse, I knew I could take her.

"Okay, okay, so now, you come be my husband, and... oh, yeah..."

She reached down and slid her wedding ring off her left hand, holding it out towards Jodie. "I think you dropped this?"

"Oh, silly me!" Jodie took it gratefully, sliding hers off in turn. "And yeah, I was gonna say, you left this on the dresser..."

As each placed the other's ring on her hand, Ted proffered me his with far less subtlety.

"Here you go."

My conscience yowled like an injured cat as I handed my ring over to the old fuck, putting his on my hand. I couldn't believe everything fit. A little loose, perhaps. I stepped over to Christine and slid a hand round her waist, holding her against me and feeling that excited sway, her hip brushing my cock as we took in the sight of Jodie and Ted, mirroring us, Jodie resplendently overdressed.

He had my ring on. Why had I let him take my fucking ring?

"So, darling," Ted purred, Jodie nuzzling into him, "you never tried this bike out in your new dress."

"Yeah..." she mused. "Should I see if it's dress-worthy?"

"I shouldn't think you'd want an exercise bike that you couldn't ride in a silk gown, my love."

I couldn't help it. My hands slid up and down Christine's lycra covered belly, finding my way up to feel her breasts through the fabric, delighting at the gasps she made, through my shame. We watched together as Jodie mounted the bike once more, this time in her elaborate dress, and pedalled. Christine's hand found my hard cock through my sweats, and squeezed, rubbing slowly, and I groped her in turn with the same casual aggression he had taken with Jodie.

Ted's hands were sliding up and down the silk covering Jodie's torso. She threw her head back and breathed deep, audibly, beginning to sweat as the exertion and his touch pushed her arousal higher. Her squeezed and stroked her breasts and her ass, which lifted off the seat, and she squirmed, grunting, even as she pushed the pedals. He pulled at the fabric, dragging the dress up off her legs and up to her waist, baring her ass and her deliciously round hips. He pulled her thong sideways, and slid his ring finger, wearing the ring I had exchanged with my wife, deep in her cunt.

"Fuck yes..." she grunted, and paused, frozen with her ass up as he fucked his finger into her.

"Keep riding. Come on." She took the command as well as she could, moaning horribly as her legs pumped the pedals again, her hips now rising and falling on his finger, his other hand keeping the dress bunched up at her waist. She couldn't seem to work the machine very quickly or stably in this state - shuddering, slow turns as it clunked and rumbled and each heaving deep breath released a guttural moan.

My arousal spilled over and I grabbed Christine by her hair and our tongues wetly slid together, lapping at each other in greedy, sloppy, over-excited kisses. Her hand grasped under my waistband and found my cock, pumping it in a tight fist and groaning with excitement into my mouth. I moaned in return, reaching hopelessly for her pussy and confounded by our height difference. I pulled at her waistband and she helped me wriggle her overly tight shorts to the floor. Out of nowhere, compulsion guiding me, I gave her ass a hard slap, and pulled back to see her face gleeful and joyous. With the sound of Jodie's moans growing ever more erratic atop the bike, she pulled me over to the bed and crawled up on all fours, wriggling, taunting me to repeat myself.

I gave her another. A hard smack across both cheeks. Susan would never let me spank her; Christine only pleaded for more. Again. Another. Stinging my fingers and soft red prints rising on her haunches where I'd touched. Her thighs, too. The enduring sound of Jodie's sluttish groans and the harsh whack of my palm against Christine's skin. Her knees spreading wider, her pussy shaved and so fucking pink and pretty, glimmering with her juices. I knelt down behind her and buried my face in it.

Behind me, Jodie's voice took on a new tenor, and the words "oh, fuck" staggered out of her lips. One day, much later, she'd clarify that this was the moment he'd started licking her ass.

I sucked energetically at Christine's clit, pulling it into my mouth and licking with frenzy before releasing it, spreading her wide with my hands grasped round her thighs and sliding my tongue up between her lips. I loved the sound of her moaning so much - so joyful, no shyness to speak of, she was the happiest to have her cunt eaten with such glee. I tilted my head and sucked at her clit once more, pushing two fingers into her hole and fucking a slow measure, delighting in the feedback of her hips writhing backwards into my face.

Behind me, I heard Jodie clamber shakily off the bike, and the slippery sound of urgent kissing, and of fabric being hurriedly pulled aside and tossed to the floor. I stood, discarding my clothes, and Christine rolled over, beaming with pride as she removed Jodie's top from her chest and she spread for me. Mounting the bed, I pushed my hard, wet prick deep into pussy, pinning her wrists behind her head as she arched and moaned at the penetration, rolling my hips forward to fill her and enjoy her deep, sweet warmth squeezing my cock without a shred of care for the meaning of what I was doing. She arched and squirmed off the bed as I pounded into her, moaning together, her eyes shifting between rolling back and staring into mine as she howled the word Yes over and over.

And suddenly Jodie was next to us, on her hands and knees, ass in the air and waiting for Ted, who knelt next to me and guided his cock up into her cunt, exciting a soft "yes" from my pretend wife as it found his depth and he too fucked with that particular, desperate aggression I felt too. As Jodie moaned so fucking sweetly and her gorgeous body bucked and shook she looked back into my eyes and smiled with gritted teeth, an evil grin that shared in the unbelievable rush of betraying our lovers together with barely a hint of a question. Ted's moans of pleasure were no less creepy to me, even now. I wondered how many they'd claimed like this. Jodie was another thrill-seeking slut they'd yanked out of propriety. So was I.

I released Christine's hands when they pulled urgently against my grip, and she reached under her pillow, pulling out an artfully shaped and gold-detailed vibrator and holding it on her clit as it began to buzz. I spread her thigh wider with one hand and grasped her breast with the other, fucking deep and raw into her streaming wet cunt and feeling those vibrations down to the base of my cock. She and I moaned long, happy moans together as her tension skyrocketed and then peaked, her body trembling and jerking as it seized her. Shrieks, yelps, moans, contortions of her beautiful face and strange, almost painful-looking twists. Her cunt clamped down on my cock as tension and release flowed through Christine's body, until I was able to slide free, and watch her relax into the bed, shiny with sweat and barely lucid with pleasure.

Ted groaned the deep groan of his own mounting orgasm, fucking my beautiful friend as if he had every intention of releasing it inside her. Her sweaty body lurched forward off his dick, rolling underneath him and stretching out - and fuck, I couldn't believe how amazing she looked, her tits falling lazily aside and her spine arching her delicately soft tummy off the bed to accept each long, sticky shot of his cum onto her skin.

She lay there, panting, grinning stupidly, with warm cum splattered from her waist to her sternum, pooling in her navel. She giggled at me dreamily, before her stare alighted on my still very hard prick.

"Oh, you didn't...?" She shuffled herself upright as Ted crawled behind her to find his own wife, cradling her and she shuddered and moaned sweetly beneath me, seeming to forget about me in a moment as they fell into a kiss together. Jodie knelt on the floor and pulled at my wrist to come stand before her. Looking up at me, I saw the face of a friend close enough to be family, mascara mildly streaked, sweat running down her face and a sincere, familiar smile as she caressed my cock with both hands. It was near to looking at a new person; I had always loved her cheeky, friendly face, in a platonic joy that felt safe and comforting. Now, it was a weary portrait of dangerous pleasure.

She opened up that smile and closed her lips around the head of my cock in a kiss that spread out and enveloped me, cleaning Christine's juices from my skin with satisfied, muffled moans, and replacing them with a generous measure of warm drool. I gasped, happily, then moaned, and breathed and then spoke her name with my fingers dragging in her short cropped hair. There was no latitude left to deny that I had done all of this because I wanted her. That doing this with her was the meaning in all of it. And I didn't even know if she felt the same, even as her neck jerked to fuck her warm mouth onto me, her tongue scraping and lapping, palms gripping my thighs in unmistakable worship. I felt longing for her.

And that would have been enough to push me over the edge. But with that realisation swelled a resurgence of my guilt, as if I had only been able to suppress my conscience as long as it could all be waved away as frivolous and meaningless. No, this was betrayal. It was the rush of that debasement that became my orgasm. A first stream of cum shot onto Jodie's tongue and her eyes widened, drawing back and still wearing that smile of contemptible elation as more followed, shooting jets of warm, white fluid onto her lips and cheeks, her eyes fearlessly open to keep contact with mine as I coated her. My friend's wife. My wife's friend. My friend, whose face was now dripping with my own cum, both of us panting together and sharing in this grateful mutual worship.

She stood up, her legs shaking. A euphoric mess of sweat and cum. She had had no orgasm, no release. Simply high, riding the joy of the event. We looked at the bed. If they weren't sleeping, they were certainly very still, and near out of it. She looked back at me.

"I... we have to do this again. Right?"

"Yeah... I feel... yeah..."

"Together. You and me. We have to keep this... we have to find others."

I already knew who. Bring it full circle. Dig the hole even deeper. "Tom and Susan."

Jodie's face spread into a grin of unabashed delight. Ted and Christine both sat up off the bed. "What? With your...?"

"Different Tom and Susan" I said, hurriedly. It seemed to satisfy them.

They were hospitable in the aftermath. Everyone got their own wedding ring back. They let us both shower, and we - with shaky legs - dismantled the bike and brought it down to the car, along with several clothes that Jodie had liked. That blue gown, especially. On the drive home, we hatched a plan for her to wear it in the initiation of another encounter with our spouses. If we could close the loop, draw them into this thing we had discovered, then perhaps it wouldn't feel so wrong, over time. Still, everything was out of order now. As we embraced, and said goodbye, we knew this was something special between us. Vital. Something that, perhaps, could never be squared with our loves. What do you think?

"I can't fucking deal with this."

My poor wife. It was barely a whimper. Neither of us handled heat well, but it was especially bad for her. She always got less rational, moods erratic. I wanted to hold her close, but, well, we were both drenched in sweat. Both of us in cotton shorts and vests, losing our minds in a hot train car. Which hadn't moved in half an hour.

There had been an announcement, something to do with a fault related to the heat wave, but it sputtered out. We'd decided to make a break for the swimming pool after our apartment got intolerable. We knew the trains would be baking hot, but it seemed worth it for the respite. Now, we were stuck underground, sweating through our clothes.

The train was empty enough that we could stretch our legs out in the accessible seats. We'd kicked off our sandals. There was another couple, at the other end of the car, and from the looks of them they weren't faring much better. They were both swigging from disposable water bottles. I looked back over at Sandy, her brown hair clinging to her shiny forehead. This was actually scary.

"Babe, I'm going to ask them if they can share some of that water, okay?"

She nodded weakly, and waved. I unstuck myself from the seat and meandered down the car. Every movement felt like opening an oven.

"Hey, sorry guys." They both looked up. They hadn't noticed me and I didn't blame them. Despite bearing an equivalent sheen to both of us, up close, they seemed a little more chipper. "I'm Aaron, that's Sandy..." I glanced over them again. Sandy knew I had a weakness for brunettes in glasses and I knew she was equally drawn to noticeably older men with a nice balance of muscle and squish. "Uh, we don't have any water, do you..."

He just nodded, and reached under the seat. Out slid a crate full of those bottles. Smart.

"You wanna come sit down here?" I called down the car. She did a worse job of shambling over than me. Hot weather always was virtually disabling for her. What she needed was a cold bath. She looked barely lucid stumbling down the car, but she rallied with a smile when she met our new acquaintances, Tomas and Julie.

"Sorry, this is objectively a worst-case situation for me," she sighed, and swigged the water they'd given us.

"That's alright, it is a little scary. We kinda love the heat, we do sauna all the time." Tomas had the deepest voice I'd ever heard. He was dressed similarly to me, while she wore a blue cotton sundress that was clinging to her body and I was struggling not to stare. I agreed with his assessment - things were frightening, but I was avoiding that point for Sandy's sake.

Julie smiled. "Let's not panic. Hey can I say something weird?" I shrugged. "Okay, I love all these scents. You know, I always loved the smell of people."

The car was humming already. I was especially self-conscious. I didn't like strangers smelling me, but I wasn't alone, and I found Julie's perspective quite charming. She was already tossing Sandy another bottle. I definitely recognised Sandy's more intimate scent, in the air, and wondered if the others were picking up on ours.

We all chatted a while. They were on their way to the pool, same as us. We figured out we had a friend in common. Julie and I liked some of the same bands. But I was picking up on a discrepancy. I wasn't getting a lot of eye contact from either of them. They were looking at Sandy a lot, and Sandy was slouching and, while looking pretty out of it, returning their stares with a goofy smile that I remember first seeing the first time we kissed. And I thought it might be nothing - maybe they were just concerned.

But when my sweet love was halfway through her second bottle, she blurted, lethargically, "is it bad if I just dump this all over myself?"

They both giggled. "I can't imagine that being bad," Tomas said.

I knew where she was at. Her patience was shot and she was acting on impulse. My wife upended the water on her chest and shook out the rest down to her legs, making her already wet ensemble translucent. I half expected steam. She sat panting for a moment, her nipples exposed through the cotton shrinkwrapping her tits.

"There," she gasped, gesturing at her dripping carcass. "Enjoy."

"We will," grinned Julie.

I tried to assemble a reaction to these two eyefucking my wife.

But then the loudspeaker came back on. There was no little chime; the voice that came through was distorted, barely perceptible.

"Hey everybody, we're working on getting things moving. We're very sorry for the delay. We think it'll be another 30 minutes, no longer. Hold tight. Sorry."

Sandy just whined.

"Well. Fuck." Julie fished for another bottle of water. "Well, you want another one?" My cute and very exposed wife, slouched in waterlogged polyester seating, nodded. I didn't know if she thought Julie was offering her a drink, but Tomas' grin widened as his troublemaking spouse got up, strode over, and poured a full bottle of mineral water all over Sandy. Her clothes saturated, it cascaded off her onto the floor. I was shocked. And incredibly nervous. I glanced at Tomas, who caught my eye with a sinister smile.

Sandy broke out in giggles. "Thanks," she sighed. "Thanks..."

Julie sat next to her, and slid her hands up and down the sodden vest. "She's really hot, huh?" She grinned. I nodded a paralysed "mm-hm." She laughed, as people do when assured they're the most confident in the room. She turned to Sandy. "Wanna give me one?" My wife nodded in certainty. Tomas was already tossing another bottle over.

Julie reclined alongside Sandy. "Go for it." Sandy seemed more energetic. The cooling was helping. And it was clear that she was enjoying playing around. She unscrewed the bottle, took a little swig, and then poured out it out on Julie's sternum, down to her navel, and back up. By the time it was empty, the soaking stranger had reached both hands up to my wife's chin and pulled her in to be kissed.

Sandy kissed back. I could barely handle the sight, both of them dripping wet and kissing hungrily in the grimy and sauna-like carriage. I could hear Sandy's squeaks of excitement. Both women were smiling with utter elation. I didn't even know she liked girls.

"Uh..." I felt I should make some effort to stall things and talk it over. This was my marriage, warping beyond recognition. I glanced over at Tomas, unsure why I'd expect him, based on his reactions thus far, to share my shock. His shorts were bulging horribly. I realised mine were too. He caught my eye again.

"Enjoy it, dude."

I looked back. There was little left to imagine after the water, but the rush was unbelievable at Julie's dress being torn down to bear her tits, shiny with water or sweat, Sandy's hand immediately closing around one of them and squeezing happily as they kissed. Julie had yanked Sandy's shorts frantically halfway down her legs and reached for her smooth pussy, teasing her clit with the length of a finger, Sandy's hips rising and falling gratefully.

I can't tell you how fucking hard I was, or how confused. I hadn't sanctioned a thing, yet my whole body wanted this, and I could see that Sandy did too. But we hadn't had a chance to confer. She was in Julie's clutches so fast. Beyond my reach. Moaning, kicking her shorts off; Julie's middle and ring fingers found their way inside my love's pussy and eagerly fucked. I could see the tension in Julie's shoulder with the motion. Sandy reeled off the kiss and moaned openly, her eyes swiveling towards mine to silently beg permission. I couldn't think what else to do, so I stroked her hair in assurance, knowing I was visibly squirming, my cock wanting out. Julie had peeled Sandy's vest up and was licking and sucking at her pert, pale breasts.

Things had fallen apart into in mere moments. I ached at the sudden end of things as we knew them, and I wanted to go deeper. As deep as she had already gone. Tomas was already tearing off his clothes and piling them on the seat next to him. He was tall and bulky, and his dick looked fucking furious, vein-strewn and slightly curved. I knew he expected to fuck my wife. It was foregone. He had already decided that he would have her and I couldn't think what to say about that. As aroused as I was, I wanted to stop him and I didn't know how.

He strode over and was on her, their lips locking in a sweaty kiss, his hand gliding down her throat and chest, groping her freely, the threesome now virtually ignoring me. I still had my hand in her hair, on autopilot, stroking, nauseous with fear and envy, my whole lower body thirsty for whatever could be next. I glanced down and her hand had already closed around his cock, stroking excitedly, her fingers trembling. She arched and squealed as Julie's lips found her clit, and as I stared at her feasting on my wife's pussy, her eyes alight with sinister glee. Like she knew my fear. She was the one dragging us down this hole. We were all trapped and this would carry on no matter what. I was being dared to do something about it. Taunted. The sound of my wife's muffled moans in time with those of this brute kissing her, being pleasured by her.

He reared upright so that his cock was level with her face, and I made a desperate bid to pump the brakes. I looked at her, formed my lips to say "wait, don't", stalled by the maniacal smile she flashed back at me. Droplets rolled down her face. A stare of wordless "sorry" before she turned away and wrapped her mouth around his cock.

Wounded, I pulled my hand off her hair and it dropped to my side. The rising feeling of betrayal swelled over; her neck and jaw working frantically to draw him in, massaging his cock with her lips. The sense that she didn't care enough to resist for a second and catch up with me. For an instant, it felt like I lost her. And it felt like they'd seen how weak and overwhelmed she was and took that for anything they could. Both his hands took her hair, grasping and caressing. He groaned openly, wearing a grin and a grimace. I caught his eye again; the same look of entitled joy Julie had. And then he lost interest and looked down at her and I saw her staring up, in spite of the harsh light, into his, her lips and tongue gliding adoringly over his veins.

I was so preoccupied and hazy that I might have missed Julie hastily repositioning herself in front of me. But my hips obligingly lifted off the seat for her to yank down my shorts, causing my cock to fling several drops of sweat and precum onto her lips. A plume of vapour followed. I felt the trapped heat rise off me and smelled myself, pungent, salty. I saw her drink it in, too, remembering her love of our scents. She locked her eyes on mine and I couldn't look away; her head dropped and my cock filled her mouth, causing me to groan and shudder with sudden pleasure.

She sucked hard, pulling back and cleaning the sweat from my cock. Even over Tomas and Sandy's grunting - more feral by the second - I heard the gulp. My cock now dripping with saliva, she kissed her way back down my shaft, staring straight at my face as she licked my balls clean, and dipped behind them to lap up the last of the sweat. The sensation of her tongue scraping my perineum made my cock stand on end. She slid her hands up and interlaced her fingers with mine, squeezing in reassurance, as if my unease was known. She returned her lips to the head of my cock and smothered it once again. I threw my head back, moaning "fuck", staring at her adorable face dripping with sweat and stuffed with cock against the backdrop of the seats and windows, which only revealed the tunnel's blackened bricks.

Next to us, as Julie's lips slurped and smacked, Tomas took hold of my wife's arms and pulled her upright, grabbing her by the shoulders and walking her to the opposite side where they had first sat. Now I could see everything they did past Julie's head. But the heat was harder than ever to bear, as our collective arousal worsened the temperature. I was struggling to focus, and panting out my moans, sweat coarsing. I saw Sandy shed the last of her clothes. I saw him take hold of her again, and felt a protective ache as he forcibly positioned her, urging her to plant her bare feet wide on the filthy floor and proffer her posterior up to him. Her body was glowing with the fluorescent train light. That was before he unscrewed another bottle, downed roughly half of it, and poured another cascade of water all over her back. She pressed her hands against the windows, he positioned himself behind her, and my emotions swirled as he slid his cock inside her body as deep as he could, producing a barely recognisable howl from my love, and began to fuck her.

Honestly, I wanted to get over there. I wanted to be there to make sure she was safe. My jealousy was fading with every euphoric gulp Julie took of my cock. But Tomas was being so rough with my wife. Gripping her hair and pressing her face into the glass as she screamed and moaned, his hips slamming into her ass. I could see his balls swinging with each thrust. She was being fucked so hard and so aggressively, and I knew that in the heat it might take all her wherewithal just to keep her posture.

Julie was already climbing onto my lap, grasping my erection and sinking down onto it. Her body heat was excruciating; my cock felt suffocated, and she didn't waste a moment to begin rolling her hips, her pussy claiming my cock and squeezing me inevitably towards climax. I wrapped my hands around her, gripping the dress bunched around her waist, and found myself thrusting instinctively upwards as her lips closed on mine with a kiss filled with deep, mutual moans, and I forgot all about my wife.

For only a moment. The car was ringing with her screams. I knew those screams. Staggered and inconsistent. Sandy was in the midst of a hard orgasm. I leaned around and saw how she was still upright - the vast Tomas was holding her there by her arms, pounding his cock into her, undoubtedly squeezed tight by the spasms of her climax. And even as those screams died, he was still holding her up, limp and panting, relentlessly fucking her against the window.

Julie saw my concern and climbed off me, grabbing my wrist and pulling me across the car to be next to them; emulating Sandy's pose, reaching back to pull herself open and invite me in. I needed to fuck as much as I needed to check on my wife, and I slid inside her without hesitation, throwing my hips forward and claiming my pleasure from Julie's pussy. She reared her head back and moaned beautifully. I never stopped moving, but looking at Sandy, I could see how weakened she was. Barely hanging on, but committed to the very end, looking up at me weakly with every lurch as Tomas fucked and fucked. I reached up to the window and grabbed her hand.

"Mm... sorry..." she gasped, delirious.

"I love you," I said. I was barely lucid, either, but I couldn't stop. The flex of Julie's back and her soft ass glistening as I buried my cock in her.

Tomas roared. I hadn't even thought about it. I saw him press Sandy's face hard into the glass as he stopped thrusting, trembling dramatically as he grunted and wailed, Sandy's expression turned to enraptured, gleeful shock, and I knew that beastly cock was pumping cum deep into my wife's pussy.

"Fuck. Fuck... oh my god..." Sandy whimpered, over and over. Tomas staggered backwards out of her and I heard several large droplets hit the floor. She collapsed into me and rested her head on my shoulder, caressing my back and my ass and whispering "do it."

"Do it, fucking do it, yes," moaned Julie, her free hand working frantically between her legs. Her fingertips were grazing my cock as I fucked into her. Tomas had sat down next to Julie and was kissing her lovingly, calmly, as I grasped his wife's hips and felt her clamp down, screaming into his mouth with her own violent, trembling orgasm. That squeezed pulled me beyond, and I lurched forward, burying my forehead between her shoulders and groaning as my lower body seized, her orgasm wrenching the cum out of my body and into hers, my moans and hers saturating the dangerously humid air.

The train groaned to life. Dizzy, we collapsed onto the row of seats, reunited with our own lovers. I held my shaking, exhausted wife close. We were already moving. We'd have to get these ruined clothes back on our bodies before we saw daylight.

"We need to get out of here," I murmured to Sandy.

"Absolutely," Julie panted, nuzzling into Tomas' chest. "Pool's still open."
