F/F, encasement, latex, insertion

Dash and Vinyl have been going out for a year now. They share a love of bondage but they could never get enough. With jobs and other commitments they could spend a day or two in bondage at best, yet still wanted more...

They take 3 months off in the summer to explore their deepest fantasy of long-term encasement, knowing they'll spend the next three months tightly bound together in a small black box...

Based on the art by Kinky Rainbow Dash (KRD) of two mares having the time of their lives.

Dash followed Vinyl into the room to check on their preparations, and once again lost her breath at the sight before her. A polished black, box the size of a coffin, sat on the floor of Vinyl’s room. The only break in the smooth material was a small display to monitor the ponies that would soon be inside.

Dash set down her bag with the final parts of the harnesses they’d need for their vacation. Everything that they needed was there, it just needed to be assembled.

Vinyl was smirking and walked up next to her. “Hey, you’re sure about this?”

She let out a nervous chuckle. “Pfft! Yeah… it’s just three months, and you’ll be right there with me.” Dash couldn’t tear her eyes away from the box. Despite all her kinks and her love for Vinyl, it was still surreal to think they were actually taking their love of bondage to the next level.

Given that they both had jobs, they’d never spent more than a few days in bondage. However, to celebrate their first year together, they’d gotten time off work and gone all-out buying the equipment they’d need to spend a truly special summer together.

There was a knock at the door. “I’ll get that,” Vinyl said.

While she was gone, Dash opened up one of the boxes of toys they’d need for their adventure. Sets of tubes wrapped in sterile packs were set alongside gel dildos and plugs. Looking at them like this, they looked like some sort of silicone octopus that was going to climb out of the box and attack her. However, this series of tubes would be their life support while they were inside. Dash had selected the dildos herself to make sure she and Vinyl had a good time.

Going to the box, she examined the latches on the side. Dash clicked and unclicked each of them a couple times, testing them. There’d be no way an unrestrained pony inside could force the lid open, and Dash would be far from unrestrained.

She propped the lid open and looked at the deflated gel padding. It was seamless except for the small ports where tubes would run to the outside to supply them air, nutrition, or eliminate waste. The access panel to all of them was on the outside. It could sustain itself and the ponies inside for months with minimal maintenance, and one of Vinyl’s friends would house sit and keep an eye on them.

“Dash, Pristine Shine is here. You’re ready to get started?” Vinyl asked.

She turned to face the stallion that walked into the room. He was a teal pegasus with a golden-blonde mane and tail who was known in Dash and Vinyl’s circles for being a model and long-term bondage enthusiast. It was rare to see him without wearing some form of bondage, and even now he had tight bands pinning his wings closed.

“Yeah, ready as ever.” She smiled to hide her nervousness as her heart raced, excited at the thought of surrendering her control and sealing herself into the box with her lover. “Hey, Shine, you’ll be okay keeping an eye on us for a few months?”

He nodded. “Yeah, I’ll be living in Vinyl’s house while I do.” The shy stallion was at home around all the devices they had here, having worn most of them on himself before. He began to unwrap the things they’d need first in a rather professional manner, considering he was in a room with two naked, and soon to be helpless, attractive mares.

“You haven’t eaten and you remembered to shower and get rea—”

Dash cut Vinyl off with a kiss, savoring the taste of her lips for the last time this summer. When she finally pulled back they were both blushing. “Yeah, we’ll be fine… right there next to each other, so close and so far away.”

“Heh,” Vinyl rubbed her fingers in her hair. “Well our catsuits are in the closet.”

“Don’t get ahead of yourselves,” Shine said. He had laid out a set of plugs and tubes to be attached before they put the cat suits on. “Which of you ladies is first?”

Vinyl and Dash looked at each other for a moment. Dash was nervous, but far too excited to resist going first. “I will!” She gave Vinyl an assured glance to remind her Dash was too awesome to get worried over a little long-term bondage, even if it wasn’t true.

Dash sat down on the towel Shine had laid out. First he handed her a small vibrating ring. “Go ahead,” Shine said. Dash spread her legs apart and first removed the piercing she had in her clitoral hood. Vinyl had gone with her to get that one after they’d met, and now that the pain had passed it was her favorite piercing. Dash put the new vibrating toy into the piercing and clicked it into place.

Shine held out the silicon-gel butt plug. It was an expensive model, self-lubricating and able to change size, length, and vibration at any point on the plug. It would prevent Dash or Vinyl from getting habituated to the sensations, and ensure they felt every second of vibrations.

“Go ahead,” Dash said. She looked at Vinyl, who was subtly rubbing a hand along her thigh as her girlfriend sat there being plugged. Dash let out a soft yelp as the plug slipped into place, more from surprise than discomfort. The gel quickly warmed and molded its shape to perfectly fill Dash’s rear.

The dildo was next and Shine waited for Dash to nod before starting. He spread her labia with two fingers and began to gently guide it in. It was a similar gel to the plug, though much larger. It was measured to fit perfectly inside her, touching the tip of her cervix. Dash couldn’t help but let out a moan as she enjoyed the feeling of fullness. There was a wet slurp as the gel sealed against her, holding itself in place for now while Shine attached the tubes to the plug.

The third and final tube was attached to a small catheter with a bulb. Dash frowned, this part could always be a bit uncomfortable. However once it was in place, the vibrations in her urethra would add yet another layer of pleasure and torment to her vacation.

Shine was able to slip the catheter into her urethra with practiced ease. He took out the small, five milliliter syringe, and inflated the bulb. The small vibrator in the bulb sprang to life for a second as it was attached to the controls for the dildo and plug. The set of three tubes would be fed out to the control box together.

Dash caught herself touching her breast in front of Shine and blushed. She was breathing quickly and visibly aroused, her body already familiar with the ritual of bondage. Next came the catsuits, the restraints, the powerlessness, and the struggle to reach orgasm. Her body was so conditioned to this that just having the gel plugs in place was enough to give her the growing warmth of an orgasm, even though Dash knew she’d need more stimulation to reach it.

Shine held his hand out with two small barbells in it. “One last piece.” Dash saw the small vibrating nipple piercings and nodded. She removed the simple piercings that were keeping the hole open and slid in the slightly wider vibrating barbells. These were of special design, being powered by magnetism. Once Dash and Vinyl were sealed together, breast to breast, they would spring to life and continue to vibrate as long as they were close together.

“Alright, you can put the catsuit on now, Dash, while I do Vinyl.” Shine was already preparing the toys for insertion into Vinyl, who had sat down. Dash caught sight of the fingers of her right hand, which were slick with her juices. Vinyl always needed a strict hand to keep her from touching herself during their games, always trying to sneak in that extra bit of edge play. Luckily it would all be taken care of for her over summer.

Dash waddled to the closet, the plugs wiggling and feeling like they were going to fall out. In actuality, they were sealed in well just from the suction and soft gel, and only the tubes to control them were hanging down.

She ran her fingers along her catsuit, slowly caressing the polished latex. It had taken all day to get a perfect shine on the outside, and to coat the inside with the special sealant to care for their skin and fur while inside the suits.

Once the suit was off the hanger, Dash began the process of stretching the neck open to step inside. She sat down and slid her legs in through the top and down towards the sleeves for her hooves. While taking a brief pause she pulled the slack in the legs up until her hoof touched the bottom of the catsuit. Next, she began to stretch the slack out and fit her entire leg inside the suit. Dash repeated with the other leg.

Both legs were in place and Dash ran her hands along the smooth rubber and admired her hocks and calves. The tight fit felt like a second skin as she ran fingers along her thighs.

Dash pulled the catsuit up past her waist, letting the tubes to her toys fall inside. They’d be pulled out the only zipper on the suit, a small opening from which her groin and ass could be reached. This same opening also allowed their tails to come out for comfort. With a practiced ease, she pulled the suit and gathered up the material on the arms. This suit was special, having only a mitten and no fingers on the hands. It would make her even more helpless as her thumb and fingers were trapped into a flat mitten.

Once she got her first hand in she flexed her fingers to test out the gloves. Her fingers were coated in the slick substance of the suit and she noticed for the first time that her fingers were slightly numb. The anesthetic liquid would numb any itching or minor discomforts while in the suit, as well as dissolve excess dead skin cells or sweat. If the unicorn who sold this to them was to be believed, and his reputation said he was, the gel would actually replicate from the sweat and continue to numb them and care for their skin.

Dash began to put her other arm in before hitting a snag. She’d always had Vinyl’s help to get the catsuit on as her wings had proven quite a challenge. At first they’d tried a single piece suit with wing sleeves. Unfortunately, in order to fit the wings inside they wound up being too loose and baggy. Dash wanted a perfect fit, so they had ordered separate latex sleeves to bind her wings in, then run through the catsuit.

“Hey, Shine, I could use a hand.” Dash smiled as Vinyl walked by her, watching the tubes dangle from her ass. Dash used her free hand to smack Vinyl’s butt as she walked by.

“Sure thing, Dash.” Shine walked over and grabbed the sleeves for Dash’s wings. “Just remember to stay calm.”

Her heart began to beat quicker again as she felt her wings grabbed by Shine. Dash’s primal instinct to not let her wings be bound told her to run, but the thrill and the adrenaline rush was one of her favorite parts. She sat still, counting the beats of her racing heart, as the wing was carefully folded up. With the feathers safely lined up, the latex sleeve was slid into place and worked down to the base of her wings.

Dash couldn’t help but flex her wing a bit now that it was in the sleeve. The tight compression was even across the wing and it looked like a third arm more than a wing now. Shine got the second wing into place just as easily, before looking down. “Okay, left arm into the catsuit.”

“Sure.” She put her left arm down the sleeve and felt Shine guiding her wings through the small holes in the back of the catsuit. The latex of her wing sleeves and the catsuit overlapped, and Shine applied a small bit of special adhesive to help the latex stick to itself and create a perfect seal. The suit would remain seamless until the two were released.

Dash stood up and looked at herself in the mirror on the wall. She watched her chest rise and fall as she admired her breasts, held upright and perky by the latex. Her padded mittens, sealing her fingers within, began to glide across her chest as she tried to feel herself. With the gel in the suit slightly numbing her, and the thickness of the latex, she felt only gentle pressure. Dash knew her hand was there, but couldn’t really feel her nipples or arouse herself with so many elements working against her.

“You look amazing,” Vinyl said.

“Thanks.” Dash turned to look at her, wearing her white catsuit with her cutie mark on the thigh. “You look great too.”

Vinyl’s tubes were pulled through the zipper and Shine zipped it back up. He then came over to Dash and did the same, allowing him access to the toys now buried and sealed inside of them. Their tails hid the tubes as they exited the only opening in the lower half of the suit.

“You did a great job on the suits. Oh, and enjoy that numbing sensation while it lasts… after a few hours your skin will become quite sensitive to touch as the gel acclimates to your bodies.” Shine smirked and gestured over to the box and the restraints. “Come now, we’re not even halfway done.”

Dash grinned as she headed over and found the magical limiter for Vinyl. It was always her favorite part of bondage with Vinyl, whereas Vinyl prefered binding Dash’s wings. She went back to Vinyl to present her with the limiter. “Hey, I got you something.”

“Alright, Dash.” Vinyl tilted her head down and let Dash slide the padded sleeve in place. Between the two layers of the sleeve was the material to block her magic, and once Dash had slid it fully into place, it was locked on by a small ring. It was just enough to keep the fabric snug and from coming loose.

“Ever feel like we spend more time getting into bondage than actually in it?” Dash asked.

Vinyl chuckled. “Sometimes, but this time will be different.”

“I guess so.”

Dash and Vinyl walked over to the box with the basic body and head harnesses from which all the other attachments would be put on. Vinyl pulled out her body harness and put it in place, though unable to buckle it shut on her own.

Shine carried over the wing restraints, similar to the ones he wore even when he wasn’t working as a model for the latest bondage equipment. He quickly pulled the straps around and buckled them to reinforce the latex sleeves trapping Dash’s wings. One buckle at the top of each wing, and one at the bottom.

Since he was already helping Dash, he put her body harness on as well and buckled it shut. He then attached the wing restraints to the body harness to keep her wings pulled in tightly against her body. Dash was as excited as ever but a bit more calm as her body adjusted to the restraint.

Dash watched as Vinyl’s body harness was locked in place, and Shine began to work on her head harness and collar. It was hard to read Vinyl’s mood from her expression, which looked rather excited, though she was still blushing. Inside her head she was probably already imagining every moment of their bondage together, just like Dash was imagining it now.

There was a faint whine as the collar was locked on and magnetized. The magic within the collar activated, which would serve several purposes. Most importantly it would monitor their health, but it also had an additional interface that would block their ability to reach orgasm. The two mares planned to be kept on edge for the full three months and only once they were out, would they release that pent up energy on each other.

Just staring at Vinyl as her elbows and wrists had cuffs placed on them was enough to make Dash rub at her groin helplessly. Seeing her girlfriend in restraints was always a huge turn-on. Each black strap contrasting the white suit, slightly pinching into the rubber the only outward sign of how tight the bondage was.

Dash hardly noticed at first as Shine had began to add the head harness and cuffs on her arms. As the collar was locked she felt a tingle of magic wash over her. She blinked and snapped out of her day dream, wondering once again if this was such a good idea, but only for a brief moment. Dash had been unable to sleep for days looking forward to this adventure, and wouldn’t even consider backing out now.

“Alright, girls, I have to ask: this is your last chance to call it off before you’re blind, gagged, and deaf.” Shine looked at them and waited for a response.

“I’m ready,” Dash said.

“Me too,” Vinyl replied.

Their heart rates had returned to normal while they were being put in the harnesses, but that changed when they saw the special butterfly gags and tubes that would soon be inside them. It looked like something out of a science fiction novel that would be hugging their faces and wrapped around their heads

Dash knew they were at the final steps and this gag would literally seal the deal. She looked at Shine, her wings twitching and betraying her nervousness.

“It’s all right, the tubes are coated in anesthetic, and you’ll drink this first.” Shine held up a small cup for her to drink with his help.

She nodded and drank the liquid, feeling her tongue, cheeks, and throat quickly numb. “Whad id dit?” Dash mumbled.

“Heh, just lay down and say ah, this part can be tricky.”

Dash nodded and laid on the floor. Shine pulled out the tubes, and using a laryngoscope, placed one into her trachea and one into her esophagus. With skill to rival a doctor, he inflated them into place. Next, he pulled them through the butterfly gag and slid the device into Dash’s mouth.

She could feel the tubes in her throat, the numbing effects of the powerful drink wearing off. It left a faint pressure and tingling where the less powerful gel on the tubes was taking effect. Dash tried to say something to Vinyl and Shine, but the air tube went past her vocal chords. The result was Dash exhaling entirely silently.

Dash gasped, feeling her throat with a gloved hand. She hadn’t had this level of silence before, and she felt her body heat up in excitement. They’d actually found a way to keep each other from making a single sound. Every moan of frustration, every whimper for release, and every cry of desire would be cut off before it was even made.

Vinyl was smiling ear to ear at her deviousness with the modified breathing tubes. “What’s that, Dash? Cat got your tongue?”

She did her best to look unamused, however Dash had a butterfly gag slowly inflating in her mouth. A few short bursts of air were all Dash could muster to try and communicate.

“Oh, you like it. Well, then after we get out I’ll have to keep that gag in for a couple days.” Vinyl couldn’t hide the grin at this point even if she wanted to. For the brash Rainbow Dash to be utterly silent, unable to brag about her awesomeness, was more arousing to Vinyl than the tight straps around her body. Vinyl wanted to join her friend in silence and spend the next three months knowing she’d gotten the last word.

Shine finished inflating the butterfly gag, carefully gauging how large he could inflate it while not making it uncomfortable to wear for months. Instead of air, he had been carefully pumping gel into the butterfly gag to make it more solid. This gel also slid into a special sleeve of the feeding tube, helping seal the throat to ensure air only came in through the breathing tube, and not the nose.

Dash felt the strange sense of fullness, and the gel which was more rigid than air. She bit down on the gag and felt it give and stretch slightly before returning to its normal shape. Vinyl was still smirking and Dash wanted so badly to say something, anything, to show Vinyl that Dash would be getting even for this little surprise.

“You’re so cute when you puff air,” Vinyl added.

Shine knelt over Dash who was still lying down. “Last step, it’ll feel weird but stay calm.”

Dash nodded, knowing she’d wanted the full experience. Shine put a syringe to her nose and began to fill her nasal cavity with gel. The warm antiseptic gel slowly filled the crevices inside her, and Dash could feel the ever so slight pressure of the gel filling up her insides. It created yet another layer of her helplessness, yet Dash still knew she wanted more.

The muzzle was the last piece to come out for now on Dash. It was locked in place, sealing the gel in her nose with small nose plugs. It held the gag fast, ensuring even a superhero couldn’t spit the gag out. And most importantly to Dash, it looked incredibly hot.

She got up and made her way to the mirror, trying to get used to this odd sensation in her nose and mouth. Dash looked gorgeous, admiring the bulge of her cheeks where the butterfly gag had been inflated. She rubbed the rubber muzzle and flexed her jaw a little. Dash knew it’d be important to have a little room to flex and relax muscles over the next few months, and was glad the butterfly gag was a bit squishy to allow her to do so.

When she was done admiring herself she returned to find Vinyl laying on her back with the muzzle being strapped into place. Dash let out a few snorts of air in an attempt to laugh, pointing at her girlfriend. Vinyl just looked back up, huffing a few times in response. She hadn’t expected the tube to be so effective at silencing her, and now both of them would be completely silent for three months.

Shine pulled out the earplugs next. Knowing the girls couldn’t protest, he removed their earrings for them. Using the piercings to anchor the earplugs, he slid them in place and clipped them shut.

Both mares looked at Shine as he spoke, but couldn’t hear a word of it. His test of the ear plugs seemed a success, as he started to laugh and spoke some more.

Dash would have mumbled something if she could, and instead looked at the imposing box. From her new perspective, tightly bound and helpless, it was beginning to look more like a coffin than a box. Dash pushed those thoughts from her head, however, as she felt the toys inside herself and looked at her girlfriend.

Shine opened up the box and laid out the final bits of straps and buckles that would be needed to secure their harnesses. He gestured to the mares to climb in.

Dash went first, as if hypnotized as she slowly crawled into the gel padding and prepared to be trapped inside. The gel began to deform and shape itself to match Dash’s form. Vinyl climbed into the box next, laying face to face with Dash and pulling their bodies together into a lover’s embrace.

Shine hummed to himself as he buckled their legs together at the thigh. He pulled it nice and tight, knowing he could go a little tighter here due to the extra muscle and fat. Shine wanted to ensure they could feel the other mare every time they bucked their hips in desperate search of relief.

Next he fastened belts above and below the knee, and around the ankle, as they had requested. These were tight enough to press their legs together, but a bit more slack to give them the slightest bit of flex while they were sealed in.

Four thicker rubber devices were slid over each hoof. Dash had sensitive hooves, and both mares enjoyed a little tickling and massaging of their sensitive flesh between the hoof. Shine tested them for a moment and saw both mares jump in surprise, the devices working perfectly. He turned them off for now.

Next, he buckled their waists together, then their chest. He adjusted the straps that wrapped around their bodies until they were smushed together, breast to breast and stomach to stomach. He could see the vibrating nipple piercings already reacting and beginning to vibrate.

Once the harness around their torso was nice and snug, he searched around beneath the two mares for their arms. The gel would deform so their arms wouldn’t get pinched or go numb. Shine attached Dash’s left arm to Vinyl’s right hip, and vice versa. He then repeated the process with Dash’s right arm and Vinyl’s left hip. Once both girls were locked together hugging each other, he rechecked all of the straps.

Shine looked down at them, making eye contact for the last time. They’d wanted to be blindfolded on top of everything else, despite being in a dark box. Shine shrugged and attached the blindfold to Dash’s head harness, cutting off her vision completely. He repeated this for Vinyl. The only real benefit to being blindfolded in a box was that the blindfolds would glow on occasion to stimulate the eyes and prevent atrophy.

Dash was already eager to test the restraints as her heart raced. She knew it was too late to turn back even if she wanted to, and knowing this aroused her even further. Dash was a powerless plaything embracing her lover for the next three months, no matter what anyone else might think.

She squeezed Vinyl and received a squeeze in response. The two mares couldn’t see, hear, or make a peep. Their only way to communicate now was through their bodies, tightly bound together.

Dash could feel Vinyl’s heartbeat where their chests were locked together. She felt her hips every time they shifted, or when Dash would try and fail to grope her ass. Dash had never felt closer to her lover than she did right now.

Shine still wasn’t done with his part. The last step was the trickiest, the girls had wanted their butterfly gags connected. They had an idea to be in a permanent gagged kiss while sealed in here.

He took rubber bands to attach their breathing and feeding tubes together. Next he placed a special ball of gel that would fill the small gap between the two gags. Shine held their muzzles together for a minute while the gel formed a seal, uniting the gags into one. His final step was to hook all the tubes up to the proper receptacles inside the padded box.

Shine checked and double checked the small control panel on the box. All the lights were green, from breathing to feeding tube, and waste extraction. The environmental controls had the gel nice and cool inside. There was even a counter to track how many times they were denied orgasm by the collars.

One at a time he clicked each latch on the lid closed, sealing them inside.

Dash could feel Vinyl’s nose and their mouths almost touching, yet blocked by the gags and a small blob of gel. She also felt a small bump, not sure exactly what it was. A moment later, the gel around them began to expand as more was pumped into the box.

Shine monitored the display as he filled the box to completely immobilize the girls in a high pressure gel padding. It would ensure even less movement, except for the movements they made against each other. Their only reprieve would be periodic, brief stimulation from the box to keep their muscles healthy before returning to a rigid state.

Dash felt her wings surrounded and pushed into place by the gel. It even crept between their necks, and the small gaps between their lower legs.

Vinyl felt her horn being squeezed by the padding, the sensation arousing as she deliberately pushed her horn around against the padding for added stimulation.

Shine stopped expanding the gel once it got to the proper pressure and detached the hose from the box. He took a step back. Aside from the mess he had made, all that was before him was an unassuming black box. Along the top and sides were eight latches to hold the lid in place. It was probably eight more latches than needed, as he’d done a good job binding the mares, but it was their fantasy. Shine sat on the box and let out a sigh of relief, having finished his arduous task of binding the girls.

Dash wasn’t aware of anything beyond the warmth and heartbeat of Vinyl, and her own toys deep inside her. There was no telling what would happen next, or when. It made Dash’s heart skip a beat as the earplugs crackled, and one of Vinyl’s songs came on. The soft music would give them something to focus on for twelve hours a day, and the other twelve would be spent in silence.

Vinyl pushed her hips against Dash’s and did her best to hold her close. Even though they were barely moving fractions of an inch, they could still feel every tiny movement of the other mare.

At long last, the toys sprang to life. Dash let out a small gasp as the dildo was activated and a small nozzle was extended. It had been specially designed to safely pierce the small opening to the cervix, and then plug it. Dash squirmed and felt Vinyl doing the same as warm gel was slowly pumped into their wombs. It continued to pump gel inside them until it reached an equal pressure with the gel in their pussy and ass.

The plug, dildo, and catheter bulb all began to vibrate and then change size and shape with a mind of their own. Dash had been building up to an orgasm from the moment she glanced into the box of toys this morning. She bucked her hips and tried to let out a moan of pleasure as the collar activated, stopping her right at the edge of her climax.

She groaned, the pleasure blocked until her body receded from the edge. Dash whimpered and wiggled her hips. Vinyl seemed to be in the same predicament, and the two squirmed there as if the collar would show mercy.

Dash sighed, giving Vinyl a soft squeeze on her left butt cheek. She received one in return, and wondered if she and Vinyl would create their own language from simple acts of groping while in here.

Nutrient gel began to pump into Dash’s throat. She felt the fullness spread down to her stomach, recalling now why she’d been instructed to not eat and to clean herself out. The thick gel was slowly being pumped through her intestines. It had been very carefully calibrated, and was slowly expanding throughout her entire digestive tract.

The fullness in her stomach seemed to quadruple as the gel reached her large intestines. She felt as if she were pregnant, her entire stomach swollen due to the gentle, even pressure of the gel throughout her.

At last she felt the pressure even out with the pushing and vibrating of the butt plug. It would slowly extract the gel as more was pumped in, allowing Dash’s digestive system to take nutrients and expel waste constantly. It also allowed Dash to feel even fuller than she thought possible. Dash felt like she needed to pee from the pressure alone, despite her bladder being empty.

Dash continued to squirm and struggle with the fullness inside her. It was so alien, yet at the same time only made her more aware of every tiny movement, every single vibration.

More slowly this time her body tried to sneak up on release. Both of her wings were rigid from the excitement, her instinct being to spread them out in a mating display. The wing cuffs prevented them from spreading. Even this aroused Dash, who loved the unyielding feeling as she flexed muscles against leather straps.

Already the gel in their suits was beginning to adjust and make their skin more sensitive to touch. The vibrating nipple clamps were beginning to reach maddening levels as they constantly reminded Dash of the goal she wouldn’t be able to achieve.

Dash continued anyway, bucking her hips as best she could against Vinyl. The dildo inside her was expanding in waves down its length, with each wave vibrating at a different speed. The gel completely filled her and stimulated every inch at once.

Meanwhile, the vibrator pushing against her clit would randomly turn on and off, giving her intense rushes towards orgasm before stopping and letting her fade back. It was far worse than the butt plug, which seemed content to slowly expand and contract for now, taunting Dash with the urge of being too full, then not full enough.

Dash tried to slow her breathing and heart rate, thinking to fool the collar. She felt her entire body heating up from it’s confinement and arousal. Her groin was quickly turning into an inferno as the clitoral piercing sprang back to life, vibrating madly against her.

She held her breath and let out one final thrust and tried to push herself past the edge of climax. The collar’s magic wasn’t so easily beaten, quickly blocking all sensation of pleasure and ending her attempt at orgasm. She felt the edge slowly slipping away, and struggled desperately for release.

Vinyl squeezed Dash once to see if she was okay, and Dash squeezed back once in reply. The unicorn had been laying there as Dash tried to grind against her and achieve orgasm. Vinyl was a bit more patient than Dash, knowing that the more she fought it, the worse the torment would become. Still, she couldn’t fight her biology and was already nearing the edge for the first time.

She tried to enjoy the ride as she approached the edge, knowing well that the magic of the collar would prevent all orgasm without fail. Vinyl could at least enjoy Dash’s embrace and the warm ride towards the edge each time. She only wished Dash would do the same.

Dash let out an exasperbated sigh. She’d lost track of time and wondered how long she had been in here. The music had come back on, or had it always been on? Dash thought it could have been a day, maybe two that they were in here? She hadn’t expected her sense of time to be completely thrown out the window.

Outside the box, Shine was sitting in a chair with his hooves up and reading a book. There was a knock at the door and he went to check who it was.

Shine opened the front door and saw Derpy. “Hi, I’ve got Vinyl’s mail here… is she home?”

“No,” Shine answered. “She left for vacation a couple hours ago with Dash. I’m just house sitting.”

“Okay,” Derpy said. “Here you go, and say hi to them when they get back for me!”

Shine smiled. “Sure thing.” He closed the door and returned to the room. As he settled down to read, he wondered in his own mind what it would be like to be inside the black box.

Derpy led Mayor Mare and the moving crew to Vinyl’s house. “I was doing my mail route when I found Pristine Shine out here. It looked like the poor stallion was hit by a carriage while bringing groceries home.”

“Yes,” Mayor Mare said. “The police report concluded the same, a horrible accident. Thanks for coming out here with us, you're one of the few ponies that talked to him often. I heard he's at the hospital in a coma.”

“Oh it’s no problem. He seemed nice and said he was house sitting, so I'll be keeping tabs on him. I’m sure Dash and Vinyl will be back from their vacation soon.”

“Well there’s the problem, Derpy. None of their friends know where they went on vacation, and they only told their work they needed three months off. They should have been back a week ago, around the time Shine died. Vinyl and Dash have been declared missing, and since Vinyl is very past due on her mortgage," she sighed. "The bank is repossessing her belongings to be sold at a future auction.”

Derpy sighed. “Oh that’s just awful.”

Dead Lift and Bench Press went inside. The two burly Earth ponies were part of the moving crew sent to pack all the belongings into a truck. They’d take them to a small storage unit at a large storage complex until the bank auctioned off the furniture.

Neither one expected what they found in the bedroom.

“What the hell is this, Lift?” Bench asked. He gave the polished black box a quick look once over.

Lift shrugged. “I don’t know, looks almost like a coffin. Should we report it?”

Bench thought it over for a moment. “Nah, I don’t want to fill out the paperwork. We’ll just transport it to the moving truck and store it. Let the bank sort it out.”

Lift nodded and left the room, coming back with two dollys. He gave one to Bench and took his to the other side of the box. “All right then, let’s get a move on. I want to be done clearing this house out in time for the Wonderbolts show.”

“Isn’t that in Canterlot?”

“Exactly, so we better hurry.”

Bench chuckled as they lifted up the box and took it out back to their moving truck. It was loaded in and left in the truck as the two went to get the rest of the furniture.

Against the wall of the truck was a small, well-lit display. It displayed eighty percent power remaining and ninety-six days elapsed. Vitals for Dash and Vinyl were both stable. They had over seven hundred denied orgasms each, and life support systems remained nominal.

Inside the box were the two soon to be forgotten mares, destined for a storage unit and possible auction at a later date. Neither one knew anything was wrong.

They began to squeeze and rub against each other to communicate. It was a crude system but after the first week they began to use it to track the passing days. They estimated somewhere between seventy and a hundred days had passed. It wasn’t a very good count, but it was the best they could do.

As the pair neared another orgasm they were denied at the same time. Dash and Vinyl groaned in frustration, looking forward to the day they got out of the box and rutted each other’s brains out. Both were secretly hoping their time was up; both feared this sexual torment may drive them mad if they didn’t get to climax soon.

Dash was jolted awake by the music, letting out a soft exhale of disappointment. The amount of sleep she got was never enough, as the vibrators buried inside her were very good at preventing her from getting used to their patterns.

Vinyl felt her wake up and they began to squeeze and hug each other. Neither one had the faintest idea how long they’d been in here, but they were sure at this point it had been far longer than three months. It was a bit frightening to realize at first, but they knew whatever happened they’d face it together.

They had both gotten very good at riding the edge of orgasm, sometimes for hours before the collar kicked in. It was probably the one benefit of being in a sensory-deprivation box that was constantly teasing you.

Dash began to approach orgasm again as her body warmed up to the new speed settings on the vibrators. She was in no rush to have it denied and just basked in the warmth with Vinyl. She felt her arm get tugged on and froze, not sure what to do. It had almost felt like she had been touched, but that wasn’t possible. They’d been locked in a box and forgotten.

Dash bucked her hips forward, squirming furiously for whoever may be watching. Without the collar to control her, and after months of denial, Dash felt her body tense up as if she were struck by lightning. It spasmed madly and Dash couldn’t breath as fire spread from her groin to her hooves and fingertips. Fireworks appeared before her eyes and the world spun.

It felt like hours before the lack of air got to Dash, and she passed unconscious.

Dash woke up and blinked, seeing something other than pitch black for once. It was a very dark, blurry room. Her poor eyes could barely focus, having had only the minimal interaction to keep them from atrophy. She rolled her head to the side but saw only a grey shape.

When she tried to sit up she quickly found she was too weak for even that, her muscles exhausted from the confinement. Dash tried to call out for somepony to see what was going on, but heard only the faint whistling of air. She lifted her hand up to her face, seeing the familiar gloved mitt on it. Dash ran the hand over her muzzle-gag, finding the device and tubes still planted firmly inside her, and running off the side of the bed towards unknown devices.

As she shifted her weight and rolled to her side, she felt the toys still buried inside her. Finally out of the box, but not yet out of the bondage, Dash wondered if something had gone wrong.

The curtain opened up and a stallion walked in. He looked at Dash, then behind himself at Vinyl. “Oh, good, you’re both awake. My name is Dr. Mustang.”

Dash looked past him at Vinyl, her hands squeezing on instinct to try and communicate with her. The doctor noticed her gaze and continued to speak.

“You’ve both been in a… well, I’ll be frank. You were in your orgasm-denial sex-toy for nearly a year before your storage unit was auctioned off. The stallion who won the storage unit found you and made the mistake of removing the orgasm control collars… you both nearly died of shock as your bodies climaxed for hours. Poor stallion thought you were having seizures and dying, ran straight to the police…

“But I digress. You’re probably wondering why you’re here, and why you’re still in your suits.”

Dash looked at him and nodded, feeling so naked and vulnerable without Vinyl firmly in her grip.

“We’re going to have to acclimate you slowly and wean you off the devices. You’ve had the machine assisting your breathing so long you can’t breathe without it, but we can wean you off slowly. Your stomachs can’t yet digest normal food. Likewise, your muscles, eyes, and bodies must recover.

“As for the collars… they’ve been placed back on. It was the only way to stabilize your vital signs. We’ll have to wean you off orgasm-denial as well, which is why all the devices remain in place… The nurses here will move you two to share a bed. We have no idea how long it’ll take to rehabilitate you.”

Dash looked over and saw that Vinyl was in a much larger bed than normal. Moments later, several nurses began to lift Dash and move her over to share the bed. Their touch was like red hot coals as her body was only used to being touched in the very specific areas Vinyl could reach.

She calmed down once she was over with Vinyl, looking into her eyes and wrapping their arms around each other. It did more than any doctor could to reassure them they’d be okay, and Dash knew she’d never let Vinyl go again.

Dr. Mustang gestured to one of the nurses to turn the devices back on. “Well then, I’ll leave you two to your recovery for now. I’ll check in weekly and we’ll see when we can start removing some of your ‘toys’. Sweet dreams, it’s not every day that two missing mares come back from the dead.”

Dash shuddered as the vibrators inside her sprang back to life. This time, the collar denied her orgasm and kept her under control. She moaned silently into her butterfly gag, and pawed at her collar with her gloved hands. The last orgasm had been beyond incredible, and she couldn’t wait to recover enough to experience another. Vinyl seemed to be having the same thought.
