"Hehehe, try all you want, but no one can defy our powers!" Ria giggled as she watched the underclassman being ravaged by the two girls on the bed. She clearly got a kick out of messing with people's heads. "God, this girl is totally going to be confused when she tries to figure out what the hell happened." Luju, on the other hand, snorted again as he looked over at his sister. "Like anything could mess with our powers. We got control over two sides of the same coin, after all. Free will doesn't mean jack shit, you know that." Ria shrugged as she tired to wave him off and focus on what was happening. Luju, though, had other ideas as he began to type in a new command for Andrea. "Those holes of her are sure getting a lot of attention but that doesn't mean we can let other things go ignored, can we now?" The two snickered together.

Andrea and Lucille continued to pant and moan loudly as they kept on fucking Narissa, driven by their lust into banging the ebony student's brains out. It didn't matter why they were doing this or whenever the underclassman wanted them to. All they knew was that they simply had to fuck her. It was such an urgent, driving, compelling need that had taken root in their minds, in their bodies. But no matter what they did, the hunger never seemed to be sated. They simply felt compelled to keep on going and going, fueled by lust into an unending threesome. Only after Andrea had cummed into Narissa did she suddenly get the urge to pay attention to the girl's swollen breasts. Her hands quickly slid over the globes, squeezing down on them as her mouth clamped down on one of the lactating nipples, sucking voraciously as she tried to lap up all the milk the underclassman could provide her.

The blunette had began already began making noise as her upperclassmen began using her body. Their own noises and grunts seemed to have no end, no matter how much she was giving to them. The rhythm of their own pelvic thrust knocked hers out, not even allowing her to control the pace as she was wrenched back and forth with the girl's thrusts and pulls. It was almost animalistic, each move more hungry than the last and neither girl slowing down as her pussy her ass sloshed with hers and their juices.

"A-ah!" she whimpered, as her head shot back as Andrea grabbed at her breast, swollen from milk and arousal as the nipple was grasped. The heighten sensitivity in the breast made her feel every ounce of milk that was sucked out of her nipple, the sensation making her groan more than she thought she could from the breast as she arched her chest up towards Andrea, giving her easy access to the aching breast whom she felt would burst if they didn't empty out.

Andrea couldn't help but suck even more deeply on the swollen teat within her mouth, teeth biting down on it slightly as she suckled harder and harder. Even then, she couldn't stop herself from thrusting hard against the underclassman, banging her hip against the girl's own as her cock stabbed into her as deep as it could go. To her, it felt as if she was in a fog, unable to see or hear anything, and feeling nothing but a powerful urge to fuck the ebony student's brains out and fill her body up with as much cum as she could. She had masturbated many times already, her body already smelling heavily of cum, but it couldn't compare to the feeling of a hot and wet cunt, especially with her throbbing cock buried inside it. Andrea moaned loudly even as she suckled, sending thrills through the heavy globe. Not only that, just tasting the woman's milk seem to ignite more fires within her body, urging her on and on. The brunette couldn't help but grab the student's breast with her hand, milking her as she kept on sucking on her nipple, swallowing as much milk as she could with some running from the corners of her mouth.

Lucille, on the other hand, was completely lost within her lust. Unable to stop fucking the student's ass, she kept humping her hip up and down, driving her thick cock into Narissa's ass as quickly as she could, having already come twice since they started. What she savored the most of all was the feeling of the brunette's cock sliding in and out of Narissa's cunt as it pressed down against her own, divided only by the thin wall between the student's pussy and ass. She was, however, quite turned on by the sight of Andrea sucking on Narissa's mound. Reaching around with her hand, the red haired girl groaned happily as she grabbed the girl's other breast in her hand and began to milk it roughly, forcing more of the girl's milk to squirt out of them. She wasn't sure what made her do it, but for some reason, she couldn't ignore the urge to do it. It was as if by ignoring it, they would have drove her mad and she was mad enough as it were.

A scream ripped from Narissa as she felt her walls begin to constrict around the sawing cocks, her body beginning to tense up as she felt her breast squeezed with all its bounty of milk. It was only a matter of time with how their own ache had began to drive her own up, her breath catching several times as she tried to gasp for air. But the other two wouldn't have it or give her a moments break for her body to stop feeling both the pain and pleasure. Unable to take anymore, a Narissa felt a jolt go up her spine and into her breast as she screamed again, her body tensing over the girls beside her as her walls closed around them her nectar gushing for Andrae as more milk pooled out of both her breast staining the sheets of whatever couldn't make it in her mouth.

Narissa couldn't take more. Her eyes fluttered as she breathed heavily, her body quivering with each slide of their veined cocks as her body slowly untensing and relaxing after such a brutal exchanges with the girls as her face turned slowly to the pillows.

"Gotta ruin my fun..." Luju grumbled as he stared at the laptop on his lap, annoyed that his sister had decided to go in another direction. The demon then looked up, seeing his sister move down the hall Andrea had traveled down. It didn't take long for Ria to arrive at the room, knocking gently on the door before entering. "Really now, girls! I told you two to behave yourselves, didn't I? Come on, calm down, girls. Let's give Miss Lorris some space, shall we?" The suggestions were very much like commands given her unique powers, and it didn't take any further encouragement for Andrea and Lucille to withdraw their cum-soaked cocks from the underclassman. This, however, didn't stop them from having more fun of their own as Andrea soon forced Lucille onto the bed, her cock driving into the red-haired girl's cunt, making her scream out in sheer pleasure.

Ria smiled as they did so, as it allowed her the opportunity to take Narissa away without them paying any attention. They were so much like sexual predators, really. Their aggressiveness, their instincts, everything going into overdrive. The lab coat-wearing Ria slid an arm around Narissa's back, helping her up onto her feet and allowed the student to lean against her. "Come on, let's get you checked out, the medical technician's waiting for you, all right?" The gentle suggestion reinforcing her hold over the ebony girl, Ria led Narissa down the hall, going past doors until they came to the right one. The succubus opened the white door to reveal what appeared to be a medical office, complete with an assortment of equipment and tools and supplies. In the middle was a chair, one very much like those found in the office of a gynecologist, which seemed logical given the nature of the emergency Narissa found herself stuck with. "Sit down, hon." Ria added as she helped Narissa into the seat.

The sudden and sole reason sounding voice broke through to Narissa as all three son found themselves listening to the doctors voice. 'Doctor?' "OoOooh." It was a slow process from Narissa's still tight walls, but the two were slowly able to retrieve their members from her clenched holes as the ebony student slowly sat herself up, looking daze and confused, much belying the true emotion behind her actions as she looked at the blond woman, her appearance the same and her face not even twitching as she practically stared at the small orgy of limbs on Narissa's bed. On the simple suggestion, Narissa felt herself emptied as soon Lucille and Andrea was going at it on themselves, a strange sight to behold no doubt, had Narissa not been spoken to next.

She brought herself up to the edge of the bed, coming up on shaky legs, her vision blotting out with dark spots as she came up too soon, relying on the woman to lead her out of the sex tainted room. She couldn't tell who was watching her as she walked naked towards wherever this doctor was leading her to or exactly how swollen her breast were, still dribbling trickles of milk as she walked, her inner thighs a canvas of white cum and juices from either girls. She was a mess, yet she couldn't spare a thought to think on it as they entered the room.

Sit down. She just needed to sit down on that large chair as the doctor said as she walked towards it, her legs not as wobbly as she made her way there, sitting back as her mind finally finished the order, freeing her for a moment to focus on other things. "What . . . what happened to those girls, doctor?" she asked, her voice still small, the drugs not yet leaving her system, but her mind slowly returning with the previous . . . . activities.

"Ah, just a couple of side effects, that's all. We're working on a solution for them, but it'll still take a bit of time, though." Ria smiled at the volunteering student, seating herself onto a chair by the desk. It wasn't so much as side effects as it was the actual effects of whatever magic she had worked around the complex. The girl before her, though, that was who she wanted to mess with now. "But don't worry about them. We're here to see what we can do for you!" The young lady in the labcoat smiled at Narissa, trying to appear as reassuring as possible, knowing that her suggestion would push the girls out of the ebony student's mind for now. It wasn't long until the medicinal technician finally arrived, another woman herself. "Hey there, let's start with the standard procedures." Receiving a nod from the technician, Ria got up and approached the chair with Narissa in it. "Don't worry, just relax."

With that, both the technician and Ria began strapping Narissa into the seat more securely, fitting harnesses over her wrists and ankles that kept her arms bound to the seat while ensuring her legs were spread wide open and propped up. The technician then stepped in between the girl's legs, using a warm cloth to begin washing off the evidence of the other girls' sexual activities and focused on cleaning the student off. Ria, on the other hand, pulled over a tray with several needles, all full of some sort of serum. Using her powers once again, the woman smiled at Narissa as she spoke. "I'm going to put these in, but don't worry about them. You won't feel a thing at all!" With saying that, she had guaranteed that the student wouldn't even feel the pinprick of the needles. Picking one up, Ria kept on smiling as she placed a hand on one of Narissa's swollen breasts, keeping it in place as she stuck the nipple with the point, injecting the unknown serum into the young lady's body. With the other needle, she did the same to the other nipple as well. Already, the serum began to do their work, a hot feeling spreading through the student's bust, tingling wonderfully. It seemed to have the added benefit of stopping the lactation for the moment, or rather preventing more from trickling out. "Didn't feel any pain at all, right? How are you feeling now?"

Side effects shouldn't have added appendages, both working and ready as the cocks on both Andrea and Lucille. If it was a simply of swollen breast would have been more believable, Narissa might have accepted it with little worries, but with every wipe the technician did with the rag only reminded her pounded and redden skin how real it was.

"Procedures?" She should have been more afraid. The paper only said a small weekend with for studies. Even her own words sounded relaxed, even as her muscles never once tensed against the restraints of the chair, her own breathing cool and tamed as if she were simply getting ready for a pedicure or something. But with the doctors orders, she simply couldn't help herself but not panic.

Her awareness came towards a tray being rolled over to her form, turning her head to see its contents before Ria drew her eyes towards her. A calm that she couldn't even explain encompassed her as she gave the doctor a small nod. 'She knows what she's doing,' she thought to herself, not even needing to feel she had to watch her pick it up or how she would administer it. Her head laid back on the cushioned chair, she felt her breast nearest the doctor puckered up at the nipple. It still felt as if it were half full, ready to seep milk again before something stocked it up from within. Looking down the student could see that the syringe was already emptied and pulled out. "You already put it in?" She hadn't even felt a thing other than her breast held.

This time, she watched her do the opposite breast and saw in awe how there was no pain at all, even as it entered the nipple. But now that she could watch, she felt them begin to heat up, almost to the point of seering from within pleasantly as it tingled.
"No . .. no pain at all," she said in a husky voice, the new weakness of her breast being exploited. "Doctor . . .what .. what was that serum?" she asked, not a concern, but more curious as they did their work within her.

"Oh, don't worry... Just a little experimental serum we're testing out. That's why you're here, right? We need a test subject to test them out on, to study their effects." Ria smiled sweetly at the girl, using her powers to keep her complacent for the time being. With the tray placed elsewhere, the fake doctor settled down next to Narissa, using her fingers to prod and test out the student's swollen breasts, giving them slight squeezes but not enough to force out yet more milk. With every touch, it felt as if they caused a burst of erotic pleasure to radiate throughout the girl's body, and with each squeeze, the girl was pushed closer and closer to the edge of reason. "The serum is what we call an accelerant. It's designed to stimulate your mammary glands. In other words, we're going to see how much milk you can procure for us. There is another side effect, however. The serum, when mixed with the drug you took, also act as an aphrodisiac."

By now, the technician would be pressing the cloth against the student's nether lips, causing strong erotic sensations to spread out through her body, pushing her to the limit even more. The 'doctor' smiled as she had the technician stop and bring the toys she wanted now. Soon, the technician and Ria were fitting what looked very much like pumps to her swollen breasts, using the light suction to leave them in place firmly. As the technician prepared the rest of the equipment, Ria took the opportunity to tease the girl by telling her what would happen. "The machine here will be using a bit of suction to start the procedure, and the tubes attached to these pumps will be carrying your milk to the canister by that machine. All of our other subjects have reported experiencing erotic stimulation throughout the procedure, very strong stimulation, I might add. They also experienced roughly between five to seven orgasms through the procedure. It seems that when you mix the drug with the accelerant, it makes your body very sensitive and makes it easier to experience an orgasm. So, enjoy it, okay? It's usually about twenty minutes, but we gave you twice the required dose, so it'll be close to an hour!"

Despite never having been in such a situation before, she found nothing about the scientist's voice that wasn't soothing or reassuring. Her attention was drawn more and more to her breast while the pumps began their pulling, suctioning the area. Already she was feeling the aforementioned tingling . . .and in more areas than one.

Teeth dug themselves into the bottom lip as she tried to keep herself from flexing, her hands spreading wide and clenching shut as the milk churned its way up with the assistance of the pressure, the serum seering her senses alive. As much as she fought it, there was nothing she could do to keep back the strangled moan pulled free from her throat, back arching as much as the restraints allowed.

Her face darkened a shade as she screwed her eyes shut, none of the milk having came out yet with the serum still working its way in her body. No matter what the nurse did, her nether lips only continued to glisten with a steady amount of her own honey seeping out,, the area warming up every time it was patted clean, only to reveal more to be offered.

"D-doctor, I . .I don't think I can take much more of this," she panted, snatch aching now with arousal and the pumps working on her at the same time, both whittling her sanity away.

"It's all right, hon. You don't have to take it, just sit back and enjoy it!" The false doctor smiled sweetly at Narissa as she picked something else from the cart, out of the student's view. It was then that the technician finally stopped cleaning up between her legs, having gotten all of the mess the others had made. Satisfied with this, Ria smiled as she fiddled with the machine, increasing the power of the suctions. Before, they had only been gentle, just enough to exert pressure on the nipples but not enough to draw anything. Now, however, the machine began to milk the student easily, white fluid now forced out of the sensitive teats and flowing into the tubes. It would be a slow process, draining enough milk to fill the canister, but it would last long enough to send her over the edge again and again. Especially when Ria was now positioned in front of Narissa, seated on the stool used by the technician who had just left. Smiling as usual, she revealed a particularly thick sex toy, a vibrator of such a deep purple color, covered in synthetic rubber with many bumps cropping all over the length.

"This'll help you really enjoy it, hon." With that, she ignored any fuss the girl could raise and began to slide the rubber cock into her drenched pussy, its slightly larger than what she had been fucked with by the two girls. The 'doctor' slowly forced the vibrator into Narissa's tunnel, not stopping until it was buried completely, snug inside her cunt. Without further warning, she switched it on, turning the setting to the highest level possible, the toy humming strongly within her. With the straps holding her legs in place, there wasn't any chance of her dislodging it, whenever by purpose or in the throes of her orgasms. "Bye! I'll be back in an hour, so have fun!" Ria giggled as she closed the door behind her, leaving Narissa to her next ordeal, the machine and the vibrator forcing her into intense pleasure thanks to the serum.

After the doctors words summed up that she would get no ease or break, Narissa hissed as she felt perked nipple pinched more by the pressure, the suction getting stronger and making her breast ache as a slow moan began pulling from her open mouth, head rolled back onto the chair as hot milk pooled out of the nipples and into the machine, taking ribbons and ribbons of the liquid into its depth. Had she known how strong they were before, she might have been able to prepare or at least hold it back, but it was simply too strong, too painful. "D-doctor, ooohhh, it's . .. it's taking it out, is. . is it supposed to do that?" she struggled with her words, peaking down between squinting eyes to see that the 'good doctor' was far from over with this segment of the procedure.

Right between her legs, the bulbous phallus held in the took not a moment longer as they pressed towards her wet and swollen cunt, having only recovered a little from their previous games as the student gasped in her seat, arms tensing as the member was worked into cavern, expanding and stretching to fit within the warm and hot space. "AhhhHH!!!!" A jump came from her body as it shut on, every muscle tightening beneath her constraints as it came alive inside her. Hips bucked and thighs clenched to either dislodge the toy or on instinct to work with it as her lips opened wide.

"An . ..an hooooour?!" came a panicked moan as she bit her lip, feeling herself already dripping with more juice as her body jumped and spasmed beneath the leather bounds, swelled breast shaking and rocking every which way with her as she was driven towards higher levels of pleasure. The closing door ensured the scream to come after that would be bound to this room as the toy revved on.

Leaving the student trapped in the room, completely strapped down, Ria giggled as she made her way back to the office she had been using. It didn't take long for the succubus to get there, and by the time she had, she was met by the sight of Luju pulling off the technician uniform, grumbling about having to clean up after people.

"Last freakin' time I do stuff like that, Ria!"

Smirking, Ria only shrugged as she settled onto her chair, feet placed on the desk. "Whatever you say, brother. All that aside, let's see how our little project is doing." She giggled yet again as she brought up the room onto the main screen, plastering the student on the screens.

Even now, it still showed the student in her chair, arms and legs strapped down and secured. By now, the pressure was surely beginning to get to her, both the toy vibrating madly within her confines and the pumps still exerting suction upon her nipples endlessly, neither one of them slowing down nor giving her any reprieve at all. This only made the succubus all too pleased, her little game getting off to such a wonderful start. But it wasn't going to stop there.

Instead, Ria turned to Luju.

"I got her all set up. It's your turn now." At this, Luju only grumbled some more before falling silent again. His hand raised up, the demon only gave a half-smirk, face painted with sadistic glee. Even if he was forced to participate on this, it didn't ruin the fact that this game of Ria was about to get worse. Downright torturous, really. He snapped his fingers once. Narissa would suddenly feel her body becoming even more sensitive, every inch of her practically tingling with sensations, as if the very air itself was pleasuring her. The force of the suction must have felt twice as powerful to her now, forcing her to feel such pleasure.

The vibrator, however, must have felt ten times worse with the girl's body stuck in a state of hypersensitivity and forced to feel the sensations of a vibrator on the highest setting. Luju smirked once again, snapping his fingers a second time. Not only did she have to deal with being hypersensitive, but poor Narissa now had to deal with another problem.

Every wave of sensations now triggered an orgasm, forcing her body to shudder with intense pleasure.

Satisfied now, the demon stared at the picture, watching what he had wrought. "There we go. She'll be orgasming nonstop for an hour." However, he suddenly snapped a third time, sending sudden waves of energy flowing through her body as well. "And she won't be passing out either. One whole hour, constantly conscious, never tiring out. How's that?"

Ria giggled as she watched. "Perfect!"

By the first fifteen minutes, Narissa couldn't tell if it was the vibrator or the machine making her shake or herself as her form began tensing towards another climax. Minutes, eternities seemed to go by as large breast continually were pinched from the machine, milk sloshing out as the student volounteer began to lose sense of time.

An hour. An hour of this was something she feared she wasn't going to come out of this without losing something, her walls constricting around toy again as it thrummed powerfully inside of her. "Doctor! .. .DOCTOR!!" she screamed as another climax shot at her from her core, back arhcing into the constraints again as her body shook again. She wasn't even allowed to come down softly at all as the vibrator continued mercillessly inside of her as her mind fought to stay conscious. Despite having been alone for . .. however long, she couldn't even tell, she suddenly felt as if someone was watching this raunchy display of her. Eyes widened, almost sure there was another in the room, but it was just as empty as it had been since the doctor had left.

Whatever orgasm she had before soon became eclisped by a quake as her mouth hung open, the whole room echoing back the nubile student's cry as the leather straps lurched with this pull. Everything became ten fold as every minute sensation through her body was being injected into her mind, her toes curling and nails biting into the leather padding of the arm rests. Thoughts were shoved into the back as cum began to drip heavily from the sides of the two, dripping onto the seat and down.

'Whats happening to me?! The Serum!?' Her body was becoming louder than her thoughts as it overrode her sensories with nothing but the pleasure the suction and toy were giving her, as if there was no room for thoughts that didn't pertain to them. A thin sheen of perspiration covered the woman's body, giving it a shine that showed just how much she was shaking or how much her breast had grown since entering the facility. A loud moan left her as she closed her eyes to this waterfall. She had never been this sensitive before, but it seem for what little left remained of the hour would surely show her.

The minutes passed by agonizingly slow, each one seeming to stretch into an eternity as Narissa underwent the procedure, her body wracked with mind numbing pleasure that flooded her entire being, lancing from cell to cell until burned with the fire of lust. The vibrating phallus inside her only made everything worse, or so much better, depending on how you looked at it. The milking went on endlessly, canister after canister being filled. By now, it must have felt as if she had sweat a small lake already, her skin entirely covered in a sheen of perspiration.

The serum seemed to have done its work, though not as Ria had explained. Milk continued to slosh through the pumping tubes, the suctions drawing them out from her modified breasts, which had already grown three cup sizes already, though they did not seem to enlarge any further. What really stood out was how the nipples felt, the suction cups tugging and pulling at the hypersensitive teats, the serum (or Luju's demonic power, perhaps) having made them at least ten times more sensitive, along with her swollen mounds of flesh twice as sensitive.

But what was certainly attracting attention from Narissa, if she had any left to focus her disoriented mind on, was the throbbing feeling within her clit. Nothing had been mentioned about this but Ria was already hitting the dark skinned student with another hit of the twin's magic, slowly remolding the girl's clit into eight inches of hard meat, already spurting and spitting up cum all over her stomach and chest. Ria giggled as Luju merely snorted, aware that her sister couldn't let a chance to torment someone more escape. By the time the hour was up, the machines stopped as the leather straps around Narissa' body snapped open, allowing her freedom while the suction cups fell away, letting her breasts lactate freely over herself. The vibrating cock, though, remained rooted inside her hot cunt, easily removed with just some effort. "Now let's see how she react to her new body..."
