Content leaving me in the very capable caresses of her apprentice, Krissa turned her attention back to Lina, still bound and spread on the table that elevated her lower back, and thus presenting her womanhood for all to see. And do whatever they wished with. Having been given several minutes of rest – the ball-gag had even been removed to allow her jaw to relax – Lina would have been content, but she knew all too well that if Krissa gave her a reprieve between sessions, the next one would probably be much longer and a lot more intense than the last. She shivered at the thought, not daring to turn her head to see what Krissa was doing in her dark corner where she seemed to find every kind of sex-toy and restraints ever made.

She lay deathly still, not wanting to shift a single muscle in fear that Krissa would make good on her earlier threat and lock Lina up somewhere with every vibrator know to demon for a week. So instead, she merely waited, listening with dread for Krissa’s menacing giggles as the silver-haired demoness rummaged around in her corner, hearing her pick up an assortment of items before approaching feet made Lina shudder again when Krissa came back to her.

Without as much as trying to make her captive aware of her intentions, Krissa shoved a new ball-gag – the plastic kind with several small holes in it – in Lina’s mouth and secured it around her head.

“Now then...” Krissa purred and rolled something beside Lina’s table. It was little else than a padded log with wheeled-poles inserted into its belly. On each side of the rounded log were four leather manacles of various sizes, and it wouldn’t take anyone much time to realize that they were for restraining both wrists, both upper arms, both thighs and both ankles of the person lying on top of it. “Time for a change of scenery.” Krissa giggled, and in a flash cast a paralysis-spell on her re-gagged captive, making the raven-haired demoness limp in her bonds. With little effort despite their similar sizes, Krissa undid Lina’s current restraints and put her thrall belly-down on the log, spreading Lina’s hands and feet to secure them in the eight manacles. Not only was the position deliciously embarrassing, but it also forced Lina’s pussy and ass to yet again be open to everyone that saw her.

Krissa undid her spell, which gave Lina the use of her limbs again – not that she could do much with them. She squirmed atop the padded log to lie as comfortable as she could, but with all major joints locked down she found she could do nothing at all.

“I’m sure you’ll be thrilled to hear that I’m going to work on you personally again.” The red-eyed demoness smirked with glee, and showed Lina what she held in her hands. It was a strap-on, but an upgraded kind. It sported the same leather harness as any other, but instead of one dildo as is common, this one had two, for double penetration. Both pseudo-manhoods were dark in colour and rather big, making Lina eye them with trepidation.

“And with this,” Krissa attached the harness around her hips and thighs, doing it slowly and making lots of intimidating sexy faces to Lina. “I can ‘fill you’ much better as I do.” She snickered, then moved towards the other end of the log, running a hand over Lina’s back until she came behind the restrained demoness. “And what I really like is how you’re already wet and ready for me...” the silver-tressed demoness laughed upon seeing Lina’s state of “readiness”, then landed a hard smack on the bound demon’s right buttock with her hand.

Lina bit her gag when the sparks of pain started radiating from her ass, and with another wicked giggle, Krissa landed another smack on the opposite buttock. Lina grunted in slight pain, feeling slender burning caresses on her buttocks.

Taking a good hold of the bound demoness’ ass cheeks with both hands, Krissa rubbed the tenderized skin for a little moment, relishing in the plans she had for Lina.

And for me.

The minutes crept by painfully slow. It had gotten far enough that I no longer had the ability to count off seconds if I wanted. For all I knew, I lay in that bed with Arielle on top of me for a whole day. It sure felt like it, and all the while the merciless machine clamped to my cock dragged more cum out of me – cum I couldn’t understand where came from. My body was working overtime, it seemed. The vibrator that poked and rubbed my aching prostate and perineum seemingly urged the sperm-production to exceed any respected dairy farm, and the band that dragged and separated my balls made sure that every overwhelmingly potent orgasm was prolonged for as long as possible, lengthening my climaxes while I fed the ever-hungry milking-machine whatever I could offer it. My body, trembling from hypersensitivity and gasping for air could do little else, hence I couldn’t even manage to raise my head to look past the pointy-eared demoness to see how much of my forced spunk was in the suspended glass, and like that know how long I had left before the machine was – hopefully – turned off.

Inhuman sensations travelled from all over my body into my cock and out the opening, or so it felt like. No guy was meant to cum like this, as hard and as often as I did. And despite how I loathed these demons and their relentless milking of my cock, that part – that very small part – of me that loved being treated like this would take over more frequently, and had I had the strength I might have cried out in unspeakable bliss. But all I was able to utter were low, guttural groans and soft sobs as I came over and over again. And tied down as I was still, I could do squat about any of it.

“You’re doing so well!” I heard Arielle whisper, but I didn’t comprehend the words. “Just a couple more times, and the glass will be full!” That I did understand, and I was overcome with an overpowering feeling of relief, though I knew more cum had to be raped out of me for that relief to be a reality, if Krissa was true to her word.

“I don’t know what mistress has planned for you after this tonight, but I hope she’ll let me play with you.” The tailed demoness purred into my ear. “You have no idea... how fucking horny I am...” she said, barely audible, and I felt her hand play with herself between my belly and her pussy. She brought the hand up to our faces, and it was moist with Arielle’s womanly juices, and they smelled incredibly good.

“I hope...” she lapped the juices off one of her fingers. “I hope...” she sucked it off another. “I hope I get to fuck you afterwards...” she sighed with anticipation, eating the rest of her sweet sap off her hand. She eyed me hungrily, licking her teeth, no doubt thinking about all the things she’d do to me given the chance. Though Arielle was incredibly beautiful, I was not sure whether or not I’d like everything she was threatening to do.

I came three times more, the continued collaboration between the churning, stroking and sucking machine with the prostate-stimulator and the bands around my balls making sure the intensity of neither my climaxes nor the downtime between them receded even one bit. Still hanging between sensations all too forceful to describe, I heard Arielle call out to Krissa that the container was filled.

“Then do with him as you please for the time being.” I heard Krissa say, but had no time to ponder what was in store for me when I felt the unbelievably overwhelming feeling of the machine being turned off and removed, exposing my tender, red and lubricated cock to Arielle, who had moved off my belly to kneel beside me, having removed the milking-tube and put it aside on the mattress. Though I knew it was impossible, I could swear I heard a puff of disappointment coming from the machine when it was taken off me.

The relief continued when I felt the vibrator inside me being switched off and taken out, and suddenly my body shut down. I didn’t faint, unfortunately, but the trembling, the fighting for breath and the burning inside me retreated, and I just lay on the bed. Still. I noticed again how rope was fastened around my wrists and ankles, how my body was drenched in sweat and how I was so incredibly warm. Then I saw the suspended glass, impossibly filled all the way to the top with my cum, and again I wondered what they wanted it for.

And unluckily, I noted how my cock was still rock hard. And how Arielle was looking at it with the expression of a child let loose in a candy store.

Pleased with me completing my first milking-session, Krissa was still preoccupied with Lina to come over and “congratulate” me proper. She was slamming the double-strap-on in and out of Lina, one dildo in the restrained demon’s pussy and the other in her ass. Lina’s buttocks were both red from the continuing smacks Krissa gave with the palms of her hands, making sure to even out the pleasure from the fucking with pain from the hitting, hanging her captive between the two sensations while she vigorously fucked Lina.

Gasping and groaning through the holed ball-gag, Lina was glad that her current treatment were less overpowering than earlier, but through that contentment the black-haired demoness knew that Krissa was just beginning, and that in an hour’s time the dominant demoness would do whatever she could to make Lina cum as often and as hard as possible as earlier this night.

And Krissa could do much to ensure that would happen.
The demoness was filling her bound counterpart completely with the double strap-on, and she was anything but gentle as she thrust them hard again and again. “Let’s up the ante...” she smiled, and hit Lina’s already reddened butt another time, before she flicked a hitherto concealed button on the strap-on, which made both dildos vibrate powerfully inside Lina’s holes.

Lina groaned loud from both the added sensations of the trembling shafts and the surprise of said trembling, catching her by surprise and propelling her towards her next orgasm, which was for sure the first of an inhuman number. The vibrating, synchronized fake-manhoods filled both of Lina’s openings simultaneously, and in a potent mix of pain and enjoyment Lina came. And she came very hard, screaming through the plastic ball-gag and flexing every muscle in her restrained body as she shivered with stimulation, and of course Krissa never slowed down, pummelling her cumming thrall as fast as she could without relent.

“Oh yes...” she cooed, grinning wickedly with her hands on Lina’s hips, shoving the double-dildos all the way to the base before retracting them and repeating the process. “Let’s see how long you can hold back this time.”

Still not done with her current climax, Lina already sweated with fear and anticipation for the next orgasm, and all those that were sure to follow.

***

Though I had been given a full three minutes of rest, Arielle was no longer able to contain herself, and had settled on her belly between my legs in front of my still rigid manhood. How it managed to stay hard after all this time was astonishing, especially since it had been over an hour since last Krissa filled me with that erection-stuff of hers. Unless Arielle had been less than forward about her own abilities to manipulate my body. And then there was the band that Arielle had not removed, the band that separated my swollen balls and would keep them from retreating into my body.

My cock was raw, red and extremely sensitive, but luckily for me it was nowhere near as overstimulated now as it had been inside the infernal milking-machine’s fleshy and warm sleeve. Watching it with apparent adoration, Arielle ran a finger from the cockhead down the shaft, following the veins all the way to my engorged testicles.

“Oh how I’m going to have fun with you...” Arielle hummed with keenness, her strange and beautiful purple eyes washing over the length of my cock up and down. “I even think you may enjoy it too.” She added with a knowing smile, and I didn’t know whether I agreed with her or not. She had tied the cloth around my mouth again, so I was unable to voice whatever concerns I might have.

Licking the palm of her right hand, she wrapped it around my shaft whilst her other hand started gently rubbing my enlarged balls. Despite my painfully acute senses, her touch was wonderful, and her slow moves seemed to gently knead all painful notions from the milking-session away from me. Soon, I was grunting through the gag, actually wanting to cum again.
What the hell was happening to me? I had probably cum more times the last hours than I had for several years, and the moment they disconnected me from the device to relieve me, I was given more stimulation, and now I found myself wanting another orgasm. Something was not right...

The young demon spent a long time stroking and massaging my meat, slowly jacking me all the while shooting me looks with suggestive smiles and mouthing words I could not make out, and then she’d shift her luminous gaze back to my cock, and kept stroking it. Slowly. Now and again she moved up her head to let a thin line of spit graze my cockhead, and then she’d use it to re-lubricate my length with her hands.

“Want me to suck it?” she looked at me, mouth open and eyes beaming with bottomless passion.

Despite myself, despite knowing the dangerous road another orgasm could lead to, I nodded, the slow strokes driving me crazy, leaving me yearning for more.

Grinning, the vampiric teeth poking out, Arielle shifted to kneel between my legs. As she got comfortable and stroked the hair away from her face, her slim tail came around her hip and nimbly wrapped around the base of my cock, gently lifting it to stand straight up. It was strange to see her do that with her appendage, but the tail’s touch was as pleasurable as a knowing hand. Smiling with hunger – the kind of hunger that would never be filled – and keeping her tail around my shaft, Arielle rested her hands on my hips as her mouth opened around my cock. She started down the length of my manhood, yet her lips and mouth never touched me as she moved. When her lips reached the part where her tail was constricting the base of my cock which by now was deep in her throat, she finally locked her mouth around me and sucked mightily.

I moaned with torturous delight to feel the warmth of her, and her tight mouth started dragging slowly back up my cock while she sucked hard. Her tongue rubbed against the underside of my shaft inside of her mouth, and her right hand had left my hip to gently scrape her nails against my balls, heightening my already sharpened senses and leaving me wanting so much more.

She kept sucking me with her tail holding my manhood in place, and though she was incredibly adept at giving head she was purposely dragging it out for as long as she could, humming with my shaft inside her mouth that sent vibrations up and down me. Her slick, warm mouth and powerful suction had me tugging at my bonds, like I had done so many times this night when I was built all-too slowly towards an orgasm I might or might not get. My hips started bucking up to meet Arielle’s downbound mouth, and I tried as best I could to groan “please” through the gag.

“What’s that?” the young demoness giggled when her mouth let my cockhead go with a wet “pop”. “Want to cum?” she removed her tail from my rigid manhood, and instead captured it between her large, supple breasts. My God they were warm and soft, and I nodded to answer her query.

“Isn’t that greedy of you?” she snickered playfully, then began to gradually pump my cock with her breasts, spitting between them to make it easier for my meat to slide in her cleavage. “I mean, you’ve cum so many times tonight.”

“Please!” I tried my best to communicate, almost desperate.

“Alright, I’ll let you...” Arielle tittered, and then added under her breath so that I couldn’t hear, “Many, many times...”

She titfucked me faster now, and shortly after she leaned her head down to resume sucking my cockhead while she stroked my bone. The warmth of her womanflesh combined with the vacuum of her tight mouth didn’t leave me hanging for long, and I came inside her mouth. I moaned and bucked, limbs tugging at the bonds while my body convulsed with the extreme sensations of an orgasm that for once didn’t feel like it burnt my balls to cinders. Trembling gently, I settled down as my climax receded, and Arielle happily swallowed what I had shot into her.

And when the young demoness took me out of her mouth, I couldn’t help but notice how she was still stroking my boner with her ample breasts. Eying her quizzically – the feeling of trepidation returning – she merely grinned at me, then looked back at my cock, who I noted was starting to radiate the telltale signs of overstimulation it had felt while being milked by the machine. Thankfully, these notions were nowhere near as intense. Yet.

Arielle laughed playfully as she watched my cock, deciding the meagre amount of spunk I had fed her way too little.

“I’ll have to work you some more.” She said matter-of-factly, and put my cockhead in her mouth again. “Before I fuck your brains out...” she added in her mind.
