Jessicka was peacefully snoozing away inside her rubber prison, only to be shocked awake by all the gear on and in her body – It would happen almost every day for the last several years, but she still could never get used to it. Her pussy contracted hard around the sudden intense vibrations from the dildo inside her chastity belt, while her ass also contracted hard around its dildo, but it was sending pulsating waves of electricity that made her cry out – As if it couldn't have gotten worse, her recently added cock was being shocked too by its metal chastity cage, as were her forcibly pierced nipples. Squirming, and moaning into the rubber phallus that filled her maw – She knew she had to pace herself, because the cock-gag was attached to a re-breather bag, but with the sudden intense attacks on all of her sensitive bits, she couldn't help but inflate the bag all the way, only to get in barely enough oxygen to stay awake when she inhaled – The rubber hood around her head made sure there was no other way to get air either, it didn't have nose holes. As an immortal demon, she couldn't actually die, but it was still intense to be on the verge of consciousness while your body is forced closer and closer to orgasm – And that was what her mistress loved, pushing things to the extreme, and Jessi was the perfect specimen for doing just that. 

It was becoming impossible not to struggle hard against the straps and sleeves of the latex bolero-style straitjacket that forced her to hug herself beneath her chest – Jessi itched to claw at her mittens inside the straitjacket, but her hands were forced into fists, just to make sure she couldn't do that very thing. Her mistress had found out the hard way that Jessi could summon and de-spawn items at will if her hands were open and free, but this way, she couldn't touch the items with her finger-tips. Otherwise, she was not that much stronger than an average human – Unlike most demons – Because her power is based on latex, as secretly powerful as it might be, it also requires having her hands free. 

As if all of that weren't enough, she was trapped in her bed – It was a black, steel-framed vac-bed with a sheet of latex that conformed tightly to her body, making sure she couldn't move an inch - This particular sheet left her head exposed because a re-breather bag, but sometimes Jessi would be covered from hoof to head, and a breathing tube would be added. For good measure, her hooves were separated quite wide with a steel spreader bar that was built into the base of the vac-bed's frame.

“Good morning, sunshine! It's time to get up!” Jessi's mistress called out in a painfully sweet, sing-song fashion. “Oh wait, that's right – I forgot I put you in your sensory deprivation hood. Silly me!” She laughed darkly to herself, and holding up her phone, she waited for that certain pitch in Jessi's moans and squeals – It was the signifier that she was about to cum – Then she tapped the kill switch on her screen, turning off all the vibrations and electricity flowing into Jessi at once. Leaving the poor demon on the edge of orgasm, just like every damn morning. 

Jessicka could feel the top sheet of latex slowly release her still-struggling body as the vacuum was shut off – The usually loud device was actually in the basement, and piped up through the floor into the bottom corner of the bed – Allowing all the fun of a vac-bed, but without the high-pitched whine of the vacuum being in the same room, so it was dead-silent. Jessi slept in the corner of her mistresses room if she was a good girl, but she also had her own room just down the hall – It was essentially just a sex dungeon, where she'd get tortured in some fashion instead of sleeping. 

Jessi then felt the sheet being unzipped, and her latex-wrapped head pulled through the hole in the sheet. Her hooves were then unshackled from the spreader bar, the wires detached from her nipple piercings and exposed cock-cage, and she was lifted up, carried over to her mistresses bed, then unceremoniously dropped onto the plush black latex-covered king-sized bed before sitting down next to the demon. “We got a big day planned for you, slut!” She chirped, knowing Jessi couldn't hear her, but went about removing the posture collar first, then unscrewing the re-breather bag from the hood, and then finally slowly peeling off the hot pink rubber hood – Which pulled out long, thick black rubber cock gag as well, that had a tube down the centre for what little airflow the rebreather bag allowed. Taking out Jessi's earplugs, she smiled down at the still-panting demon, “Good morning, cunt! We have a big surprise for you! The prototype is finally complete, and you're going to be the beta-tester!” 

Jessi mumbled something out of sheer confusion, but her mistress slapped her, “Aren't you excited?” sounding disappointed, but Jessi nodded her head in compliance, “Y-Yes mistress! So-Sorry, I haven't had my coffee yet-” The dominatrix slapped Jessi's other cheek, “Don't worry, you won't be getting your coffee enema today – I want to get this puppy on you, so we can finally start testing it!” Jessi shook her head in confusion, but didn't want to risk another slap, “I-I can't wait mistress, what is it?”. Much to her hesitant excitement, and partial fear, her mistress started unlocking her cock cage, as well as her custom steel chastity belt that wrapped around the cage. Pulling the juice-slick dildo out of the demon's pussy, it was promptly shoved into Jessi's mouth without a second thought – Much to Jessi's surprise, the butt-plug was removed too. It was only ever removed for sex, swapping to a different plug, or her daily enema. Of course it was pulled out as slowly as possible, so she could feel every inch stretch out her sphincter, and shamefully, caused her now-free cock to harden up completely, which was gently stroked as the dominatrix spoke. “It's something of a dimensional portal device the lab came up with – Usually you need huge batteries to power this sort of thing, but they figured out how to make a small, portable one, and because it's so small, the batteries only need to be as big as a phone!” Jessi couldn't help but bite her bottom lip and gently moan as her mistress played with her cock, still edging, but the teasing was nowhere near enough – The woman was a voracious sex fiend, practically insatiable with her intense bi-sexual lust and love of dominating other creatures. She couldn't even help herself from licking and suckling Jessi's cock tip as the demoness pondered what the heck this dimensional portal device was – Drawing out a shiver from the rubber-wrapped demoness. Much to her continued dismay, she achingly remained on the apex of an orgasm, but the hand and lips disappeared - The dildo was pulled out of her mouth, and set aside with the butt-plug, as well as the chastity devices. 

“That-That sounds awesome mistress, what are we going to do with it?” Jessi had a feeling she wasn't going to like the answer. Without warning, the device was produced from a small bag, and quickly slid over Jessi's cock, then straps were adjusted around her waist to hold it – Similar to a strap-on belt – And the cold metal device sat snugly against her crotch, a bit like a cock-ring, but it felt quite odd to her. She could still feel her cock, but it didn't feel like it was a part of her body anymore, the weight was gone. Turning her head when the dominatrix rolled off the bed, they both widened their eyes as they saw Jessi's onyx-black dick protruding out of her mistresses crotch – Like a strap-on! “What the hell! How?” Rolling and curling up, Jessi wiggled to get in position so she could look down at her crotch – Her dick was gone! Replaced by a quietly humming circular device. 

Not that she actually wanted the damn thing in the first place, it's only been yet another way for her mistress to torture her sexually – And she was tricked into making it in the first place! She was promised her first orgasm in almost a whole year last year, if she demon-magicked herself a penis, and it ended up being a full 24-hours of orgasms – Jessi literally couldn't stop cumming that day. At first, her mistress fucked and sucked Jessi for hours – The woman had extensive knowledge of tantric sex, as well as the karma sutra, and could go for hours upon hours of pleasuring herself and partners, whether they wanted it or not. But once she finally had her fill of bondage-laden orgasms, she locked the exhausted demoness onto a pillory, and proceeded to set up three fucking machines – One for her ass and pussy of course, but then one customised with a ribbed Fleshlight-like onahole aimed at her brand new aching penis, and the devices weren't turned off until a full 24 hours had passed. She ended up having to clean the mess she made, and the onahole fuck machine had a special tube that would catch and force all the juices fed down it – It was normally used for collecting into a tank, but it was set to go right up into a dildo gag in Jessi's moaning maw, forcing her to drink every drop of cum she produced from the new penis. Jessi hasn't had an orgasm since that day, and it's been almost a whole year!

“You'd have to ask the R&D guys about that - One thing goes into the first ring, and comes out of a receiver, but it's time to test it, slut – Show me your ass.” Jessi complied as best she could, the tight rubber straitjacket made rolling over difficult, but she eventually got into position, presenting her ass to her mistress – It was promptly slapped several times on each cheek, drawing out shocked cries. Before she knew it, Jessi could feel the cold ooze of lube on her tailhole – She had forgotten to pull it to the side when presenting, which was the cause for the short, harsh spanking. “I know you love anal, so what better way to give your cock a test ride? Now you can literally go fuck yourself!” Her mistress laughed, and slowly used Jessi's cock tip to spread the lube around, then slowly pushing it into the demon's ass – Drawing out a shameful moan at the double-pleasure of both giving and receiving anal at the same time. It was an unbelievable feeling for Jessi, and her mistress quickly got to pumping the demon's dick in and out of her own ass. “And since you've been such a good girl lately – I'll even allow you to cum! But a good bitch knows they need permission, right whore?” Jessi was barely listening as her hips were pounded roughly with full strokes of her own thick meat, and her ass cheeks spanked more lightly left and right. “Y-Yes mistress! Th-thank you mistress!” She moaned out loud, squirming in her hot pink rubber bolero-straitjacket. 

Fascinated at how the device was working so well, once she allowed Jessi to cum in her own ass, the dominatrix simply switched to the demons pussy, and let the demoness enjoy the feeling of her own rippling pussy be pounded away by her own throbbing dick. The simultaneous orgasms were delicious to be had – Not worth the nearly year-long wait, but Jessi was just happy to finally be allowed to cum again and again – Even if it was in her own ass, then pussy, and finally her mouth. Through extensive stretching and contortion, Jessi has been made to suck herself off before, but it was nowhere near as fun as this! Once she ejaculated deep into her throat, Jessi swallowed, and was spanked again – Forced back onto her knees, Jessi could see her mistress was removing the strap-on, and after giving it a few shiver-enducing licks, she flipped the portal device around and strapped it to Jessi's face so that the penis was jutting out of her mouth-area. “Ooh, we need to see if they can use these to duplicate your cock too – That way you can be in all three of your fuck holes at once! I know at least this one is going into your chastity belt – So you can be inside your cunt all day!” The dominatrix spoke while rolling onto back, and removing her black latex panties in front of Jessi, they had a medium-sized dildo built into the gusset, and Jessi could see the end cap of a buttplug molded into the butt-crack displayed before her. Without missing a beat, Jessi promptly used the new-fangled device to pump her face-mounted dick into her mistresses awaiting, soaking pussy – It was a lot more difficult than just using it on her hips, but Jessi knew it was chosen to be done this way because it was more humiliating and difficult. As usual, the perfectly shaven tan crotch smelled wonderful – A mixture of the tasty juices, a hint of the latex that had previous covered it, and a slight hint of musky sweat that the latex had caused from wear. 

The dominatrix played with her own pierced nipples roughly, the black leather corset she wore had quarter-cups built in, so that it cupped her breasts, but left her nipples exposed – Just the way she liked it. Jessi had gained a lot of stamina since being trapped as her mistresses fuck-toy and dress-up doll, so while panting heavily from so much sex – She was still plowing onward, bobbing her head back and forth, gleefully pumping her dimensionally portal-ised cock in and out of her mistresses delightful pussy – Moaning deeply as she enjoyed the feeling somehow emanating from her crotch. Much to her enjoyment, the dominatrix would grab one of Jessi's horns and force the demoness into her crotch harder – Especially when she could see that she was going to cum, making her go extra fast right as she was climaxing, so that the extra sensitivity would draw out shuddered moans. 

Once they both shared in another orgasm, Jessi was pulled away from her mistresses crotch, and the device was pulled off her head – Turned around so that Jessi could clean off her still raging hard-on. It was shoved back into the demon's ass, much to Jessi's secret delight, and Jessi then went about cleaning up her mistresses cunt by tongue, “Oh you know better than that slut, keep eating~” She moaned, and rolled the two of them over so that she was sitting on Jessi's face – Barely able to breath, Jessi kept right on licking and suckling like she was forcibly taught – Working the outer labia first, and slowly, deliberately working her tongue inwards, making sure to occasionally run her tongue over the clitoris now and again. 

Finally, the dominatrix climaxed again, but sat down harder so that the demoness couldn't breath – While she enjoyed her own orgasm. Finally, after nearly a minute, she climbed off Jessi's messy face. Smirking down at the demoness, she climbed off the bed and grabbed Jessi by the horns – Pulling her to the edge of the bed, “Now come on, we have to get you dressed so we can go show the R&D guys.” Jessi groaned, she hated those people – They were wickedly good at coming up with bondage and sex devices, all of which were tested on Jessi. If the demoness wasn't set in some contraption by her mistress, they also had free reign to use and abuse Jessi for their own sexual urges without her consent – Day or night. She was normally in a straitjacket of some kind, or an arm-binder, so she couldn't resist very well either. 

Getting Jessi up to her hooves, the woman dragged the demoness off to the changing room – It was a room-sized closet filled with drawers, doors, and racks of leather and latex of all types and colours – Jessi was used to walking with dildos inside her now, but having her cock up her butt was a very odd feeling to walk with. 

Unlocking the straps of the jacket, the dominatrix slowly unraveled the straps, and pulled the pink latex off the demoness – Leaving her in just the pink thigh-highs and black leather mittens that covered her fists. Jessi knew better than to try and make a break for it, she had tried multiple times, and was punished harshly – The door was shut as well, and it had intentionally small, round door-knobs, making it impossible for the demon to use her tails or fists to open, as she as she's tried before.

Pulling out a hot pink latex corset with black piping, Jessi raised her arms so that her mistress could wrap the latex torture device around her torso – It was her 'outside' corset, with full cups shaped perfectly for Jessi's ample breasts, and stretched all the way down to her hips – It had little built-in internal nipple caps inside each cup, so it would always look like Jessi had hard nipples. Once it was laced on tightly, a panel was zipped over the laces, and locked on with a little heart-shaped padlock, making it impossible to remove the painfully tight corset except by a knife or scissors. Next, the woman drew out a matching pink latex loincloth – It was partially transparent, and had a unique way to clasp on. Holding the front and back flaps were two, two-inch wide straps that had little black metal horseshoes that each strap and flap held onto either side of the body – The horseshoes were open-side upwards, and the straps or flaps could actually slide off of the horseshoe – Jessi learned quickly how to smooth her gait, which was difficult in hooves, to avoid having either the straps or flaps slide off and expose her lower half – Especially when she is in her chastity devices – Sometimes her mistress would even add bells, which not only adds weight and make it more difficult to keep on, but the jingle draws even more attention. The reverse flap was much wider than the front one, it could cover her entire butt, but left her hips and legs almost completely exposed. The front flap was only about 5 inches wide, making it barely wide enough to cover Jessi's crotch, but leaving her legs almost completely exposed as well – Both flaps stretched to about ankle-length. It's transparency was just enough so that if you focused enough, you could see through, but you wouldn't immediately notice Jessi's black crotch. 

After the horseshoes were looped to the straps around Jessi's waist, the dominatrix picked out custom, opera-length gloves and slid them onto Jessi's smooth onyx-black arms – They covered the mittens perfectly, while still maintaining the bulbous shape of them. Turning to Jessi, the mistress spoke, “Since you performed so well today, slut, I'll let you decide where you want your dick – Do you want it in your mouth, your cunt, or do you want to keep it in your ass?” She gently sawed the black cock in and out of Jessi's ass while asking, drawing a delighted shiver. Jessi looked at the floor with embarrassment, and mumbled, “Keep it in my butt, mistress...” Smiling, the woman went to another dresser and pulled out a pair of hot pink latex bikini-style panties – Emblazoned across the rear side was the word, “SLUT” in big black letters. Jessi stepped through the leg holes without fuss, and soon found out that they also had a large internal dildo that was quickly slid into her still-dripping pussy – The device projecting Jessi's dick was also crammed back up into her rear as much as it could go, the ring was wide enough to not let it keep sliding in. When standing back up, she looked down at Jessi, “How does it feel to wear your favourite pink slut panties without your little sissy cock bulge, cunt? All while full of dick?” Trying not to growl, Jessi defeatedly mumbled, “It feels good mistress, thank you for choosing my favourite slut panties.” She hated talking like that, but she'd get a spanking, or paddling if she didn't. Slipping the battery of the device into the hem of the panties, which were quite visible from the sides of the loincloth – Worse yet, it was noticed that the battery could be mistaken as the remote for a vibrator, which made the dominatrix excited.

Giving a little smirk, the woman went to another drawer and pulled out the hood that matched the outfit – Hot pink and latex like the rest, but it had cut-outs for Jessi's eyes and mouth, rimmed with a thin line of black. After it was carefully slid over and zipped onto the demon's head, she also popped in a large black ballgag, and buckled that on. She next grabbed a medium-sized black leather collar, with a wide-band leash already attached with a sturdy metal clip – And buckled that onto the demon's neck, then locked it too, it had 'WHORE' emblazoned in pink lettering across the front. The next item was the oddest of them all, but Jessi knew what to do to avoid a spanking, and curled up her tails as best she could, like curly fries – Her mistress curled them up even tighter, then shoved them into a very tight rubber pouch with a tiny, stretchable entrance - So once the demon's tails naturally unfurled, they were trapped inside the small pouch, and no straps or hooks were needed to keep it in place. It did help cover her butt-crack, but it sat low enough that most of her ass was still visible to anyone staring. “You're lucky I'm in a good mood, cunt, thanks to that portal device working so well – We'll let your arms be free for this trip to the lab, but no fighting the R&D team!” The dominatrix stared Jessi down a bit, to which Jessi replied quickly, “Yes mistress, thank you mistress – I'll be good...”

Quickly, the dominatrix ran about and grabbed her own outfit – Keeping it much more simple, but striking. She swapped her corset out for a larger black leather one, full, custom cups that fit her large chest, and it too went all the way down to her hips. A simple black latex thong went on next, and over those, a black leather pair of pants that sat pretty high on her hips. Finally, she swapped out her shorter heels for four-inch leather heels that came up to her knees – Pushing her all the way up to 6 foot five! 

Grabbing Jessi's leash, she dragged the trussed-up demon back into the bedroom, and grabbed her purse – Cleaning Jessi's face, thighs, and butt-cheeks real quick as well. They headed outside right afterward, and strolled down the street towards her shop – It was only about six blocks away, so the dominatrix didn't mind walking – Plus it was amusing for her to see Jessi squirm with the cocks inside her. Jessi was trying hard not to moan as they walked – The dildo and her shaft jostling around inside of her made it difficult to walk so that the loincloth wouldn't slip off. They received plenty of long stares, and several pictures were taken of both of them, especially Jessi who couldn't do enough to hide anything – A few people even commented with, “Nice panties, slut!” Or, “A whore, and a slut! Wow!” Unable to resist it, her mistress even had Jessi ask a total stranger if she could cum – They thankfully said 'yes, slut', and Jessi squirmed as she unloaded into herself – It now felt especially strange to be full of cum in public like that!

Finally arriving after much embarrassment, they went around back and into the back of the shop – The research and development trio looked up as they heard the door open, then exchanged pleasantries – One of which was Jessi kneeling, and sucking the lead researcher off like always, they considered it her way to say 'hello' – Her mistress removed the ballgag so she could get to it, letting it hang around the demon's neck. It was going to take some time, so they got to discussing the portal device, while the demoness was under the desk – Bobbing up and down rapidly along the man's cock, his crotch was very musky, and more sweaty – It wasn't as nice as her owner's. They talked about how well it was working, and how amazing the battery life is, then to the topic of creating duplicates. Fortunately for Jessi, it didn't sound like it would be possible at the moment, but it would be something to work on if the product sells well enough. By the time the topic turned to seeing the product in action, Jessi had just finished swallowing the man's cum, and received a little head pat as he let her out from under the desk.

Standing up fully, the dominatrix brushed Jessi's loin-cloth aside, and unceremoniously pulled down the demon's 'favourite' panties – A smirk running across the face of the man as he saw the internal plug slowly pull out, and how messy Jessi was. Putting two fingers into her soaked pussy, with short thrusts, “So if it's not in your cunt, and not in your mouth, then it must be throbbing inside your ass, huh, slut?” He forcefully turned her around with the fingers in her pussy, and slowly caressed her ass to push the loin-cloth out of the way – Along with the tail-pouch - Before grabbing the ring of the device and slowly pulling it out of her ass – Making sure the demoness felt every inch slip from her sphincter, which drew out a moan. Of course, he promptly slid himself up into her ass without saying a word, now that it was vacant, “So how did it feel around your little cock, slut? Does it pinch, or hurt at all?” Beginning to nonchalantly saw himself in and out of the demon's tight rear as he idly fondled one of her breasts too, and studied the throbbing, drooling cock jutting out of the device. Jessi couldn't help but moan as she was casually groped and penetrated, she loved and hated that he was an ass-person too, it's where he usually started on her after the 'greeting' – Which is another reason why she received daily enemas, “I-I can barely feel it if I don't focus on it, like-like um, like panties. Ah-and I instantly feel everything, like it were attached to my body the whole time!” Giving a smirk, he pushed Jessi over  the desk, and put her cock-tip to her mouth, which she begrudgingly opened so he could slip it in. It was impossible not to suckle on her own shaft, especially since he pushed it all the way in and down her throat! He got to really pounding her ass too, “Ugh, j-just wait until we finalise it – Right now the range of the two devices is only about five to ten feet separated at max, soon, we should be able to get a few hundred feet – Maybe even a mile or more!” The demoness groaned, not only because of the hard anal she was receiving, but because that meant she'd have to test that range too! Getting her shaft teased from a mile away?! The dominatrix smiled, and patted the man on the shoulder, “Thanks for the updates, love. Enjoy my little sissy cunt, I'll go grab you guys lunch for doing such a good job on this. Just make sure to tie her leash up if you leave the room without her.”

At the sound of that, the team lead nodded to the two other team members, they went and took Jessi over to the break room – It was a fairly standard affair, with a kitchenette set up, a TV, and a fridge, but in the corner was a twin-sized bed with no covers or pillows on it, just a top sheet that got changed regularly. The first man laid down towards the foot of the bed, and the lead developer lifted Jessi onto his lap so they faced one another, sinking her down onto his cock – He then shoved her a bit so he could replace his own back into her ass, and as they went to town on her poor holes. Each taking turns molesting her breasts through the cups of the corset. The last developer had left the room to grab one of receivers for the ring, returning with it clasp to her body like a strap-on, and pulled Jessi's cock out of her mouth, mounting it on the strap-on. Jessi whined as they just so casually took her body like it was an inanimate fuck doll, but she got quieted down when the last developer moved around front – Shoving Jessi's shaft back into her mouth. They ravaged her relentlessly for nearly thirty minutes – Swapping holes, 'testing' their own shafts in the device, and even wearing one another's dick just to see what that was like, Jessi of course had to eat the woman out as well when the crotch was shoved in her face – She loved how good the demoness was at it. When they finally finished, inside the demoness of course each time, lunch had arrived and was sitting at the table. They all went off to eat and talk shop after Jessi cleaned them all off with her tongue, even laughing at how great it is to have a demon fuck doll, because with her regenerative abilities, she was always virgin-tight in all her holes! Speaking of her as an object, rather than a sentient creature. She just laid there panting heavily, covered in sweat and gagged with the ballgag again, her leash tied onto a heavy duty ring hanging from the wall over the bed – The dimensional portal device had been re-applied to her shaft, and it was currently up her ass again. She was thankful to be able to cum, but she was quite tired by the non-stop pleasure and fucking – Especially with her cock wriggling around inside her rear, and unable to have been left soften for so long.

After lunch, the two men had another round with the poor demoness who even begged for a longer break while meekly pushing on them as they put her back into position, while the female developer left to go back to tinkering on her project. When they were finally satisfied, the dominatrix returned to get Jessi – Who was drenched in sweat, her loin-cloth and panties discarded off to the side of the bed. Re-applying the loin-cloth straps, and getting the panties back onto her pet, plug and all, she untied the leash and said her good-bye's. They each gave Jessi a slap and a squeeze on the ass, mentioning how they can't wait to see her again – The demoness just groaned into her gag and squirmed as they walked out of the lab. It was a little later in the day, so thankfully not as many people were there to comment on her attire, or call her names, especially given how sweaty and smelly she must be by that point, but it was a long, aching walk back after such hard poundings – Especially still being filled with two shafts.

It was quick enough to undress Jessi from that outfit, but leaving the mittens and thigh-highs on like usual, and changing her into a latex leotard – Pink and black as always, with a stretchy hole for her tail, and a small crotch zipper that all the way down between her legs. When Jessi saw her mistress return with a stiff black leather arm-binder, she groaned, “Oh please, mistress, not the arm-binder! I'm so sore from today, please!” Giving a little snerk, “You're acting as if your day is over! Remember about this time last year?” Jessi's jaw dropped, “Oh n-no, not again!” The demoness started backing into the corner, even knowing it was futile. “Oh yes! This will be like your birthday every year! You get to get out all those pesky orgasms you won't be having until this time next year!” Given how exhausted and sore Jessi was, she wasn't too hard to catch and wrestle into the black arm-binder, despite her protests – It was a simple sleeve with chest straps that had a little pouch in the bottom to 'catch' her hands, if they weren't already in mittens, said hands would've been rendered useless. Next came two black rubber sacks that were stretched over her knees, and despite kicking as much as she could, her legs got folded together tightly – The sacks stretched over her legs completely, trapping them both in a frog tie. Producing an unlabeled vial - A special concoction of pheromones, stimulants, and aphrodisiacs – Jessi's head was forced back, and jaw forced open, several splashes were dumped into the demon's open maw – Jessi knew the taste all too well, but couldn't close her mouth to spit it out, so she swallowed it. After that was done, a a pair of ear plugs were inserted before a rubber sensory deprivation hood was fitted tightly over the poor demons head, black like the other accessories, but it did have a zipper on the mouth. A wide-banded collar was then applied, tight pink rubber with the word 'CUNT' written on the front in black.

Carrying the defeated blind and deaf Jessi into her room, she couldn't have known that there was a new device waiting just for her! It looked like one of the fuck machines, but instead of a dildo or onahole on it, there was a flat metal plate with a couple straps dangling down. The dominatrix unzipped the crotch of Jessi's latex leotard and pulled the portal-cock from her rear, and then forced the demoness to straddle a sybian vibration machine that was sat in front of the new fuck machine, the poor thing already feeling the effects, juices dripping onto the saddle – The sybian was raised a few feet off the ground, so Jessi would have all her weight resting on the large dildo and vibrating part of the saddle-like device. Next, the dominatrix pulled Jessi's head into the plate, and the demoness could feel it's slightly curved to cup her head – The straps were applied, but Jessi couldn't quite figure out what it meant yet. Soon, another fuck machine was rolled from the side of the room, set up right below the new fuck machine, and Jessi could soon feel a slimy, thick cock slide into her ass, but it wasn't hers this time – She knew what that meant, and whined out loud, which earned her several harsh slaps to her thrust-out breasts. Another metal stand was pulled in front of the demoness, and on it, the ring with her cock was applied – Aiming right at her face. The zipper was opened, and Jessi immediately opened her mouth, “Pl-Please mistress – N-Not ag-” And her shaft was forced into her mouth, muffling her pleads with seven inches of shiny black cock that was aching for it all to stop. Jessi whined around her shaft, while her mistress went off and came back with nipple clamps with a long chain in the middle – After slapping each of Jessi's breasts several more times, she pinched the nipples until they were erect – Applying the first clamp, to a sharp squeal of pain from Jessi, and then wrapping the chain around the machine behind her, before clamping it down on the other nipple. The bite of the clamps were bad enough, but the weight of the chain was making it worse! 

Soon enough, a charging cable was plugged into the battery of the dimensional portal device, and then the machines were turned on. Shouting so that Jessi could hear, “You have my permission to cum as many times as you want! I'll see you in the morning!” Laughing as the machines whirred and hummed to life – The sybian was only turned up to medium, but that would be more than enough with the second machine pumping the fat dildo in and out of her sore ass with deep, long strokes at a modest speed. The most curious one for Jessi was what her head was strapped to, but she figured it out real quick. It slowly started pushing her head further down her detached cock, and then pulling her head back, repeating the same push-pull at the same moderately slow speed over and over, but never letting the shaft leave her mouth far enough – It's not like she could twist her head away anyways. Jessi cried out, both in anger, and pleasure at the assault, but also because the way the chain was wrapped around the machine behind her – It tugged on the chain when the demoness was pushed all the way forward with the machine, causing sudden pain by pulling her clamped nipples outwards – And it just kept happening again and again, like someone firmly stretching her nipples out every couple seconds. Worse yet, she was now trapped sucking her own aching cock filling her mouth and throat over and over. It didn't take long to get to her first orgasm – And it was all caught on video! Another little something her mistress added. There was a camera aimed directly at her crotch, as it was vigorously vibrated by the sybian; another was aimed at her hooded head as it was forcefully bobbed along the throbbing cock of its owner, a third was behind all the machines – Capturing the mechanization of both fuck machines from below in one frame, and a final one was a wide shot of the thrashing demon, who was desperately trying to find a way to throw her body off the machine, but the plate her head was strapped to would keep pulling her back on, or throw her weight differently when she tried. It was going to be sold as a special-edition of the normal videos Jessi was forced to make by her mistress, and the video of her throating her own cock was going to be partially used as a demo reel for when they sell the device. It wasn't long before another climax took her, making her scream out in ecstasy and desperation for it to stop. Jessi knew she was in for a long night of forced pleasure, and with the mystery juice she was fed earlier slowly flowing through her veins.
