Chapter Text
Lucy was pretty exhausted by the idea of getting dragged into some elaborate quest. It was one thing to get sent on official guild missions, but somehow she’d ended up getting sucked into another world and nearly killed several times. The event had been so dramatic that Master Makarov had canceled the S-Class exams. Nearly a year on, it was clear that mages like Natsu and Gray were growing impatient and had started to drag Lucy on wild quests with them. While she was happy to do some good, Lucy was at the point where all she wanted was nice, quiet, uncomplicated work that paid well.
Naturally, this meant escaping from Natsu and Gray. Erza was also to be avoided. Lucy guessed they would be unhappy, but she kept focused, kept her head down, and grabbed the coziest quest she could from the guild board.
“Research assistant needed: studying sound magic on person’s mood. Duration – 1 week. Payment – 5000 jewel per 8-hour day.”
“Alright, this seems like quite the deal,” Lucy said. She grinned and tucked the flier away before sneaking out of the guildhall as another fight broke out.
Lucy found herself at a small research lab the next day. A receptionist showed her to the back rooms, where a tall man was waiting for her. He had a long, beaky nose and a bald head. He smiled kindly. “Hello,” he said, “You must by the young mage who agreed to take the job.”
“Yep,” Lucy beamed, “I’m Lucy Heartfilia.”
“I’m Hayabusa, a researcher in the field of sound magic,” the man said, “I’m thankful that somebody from such a prestigious guild agreed to take the job.” Hayabusa ushered Lucy to a table and chairs, where various files were laid out. Lucy examined the documents with interest, seeing that they appeared to contain copious notes and charts detailing the effects of sound magic on somebody’s mood. “You see, my theory is that sound magic can be used to improve somebody’s mood, potentially allowing for a new field of sound therapy to emerge. However, I’ve yet to test this hypothesis on a willing participant.”
“Which is where I come in, right?” Lucy asked.
“Exactly. I’m going to play various recordings of sound magic, and I’m going to need you to tell me how they affect you,” Hayabusa said.
“Got it! Leave it to me,” Lucy said.
Lucy settled into a chair. Hayabusa attached several metal pads linked to wires to Lucy’s arms and head. He then stepped back and took out a gramophone. Lucy was surprised to see such an old instrument, and equally surprised to see Hayabusa take out a record and load it into the track. “This is old, inscribed sound magic,” he said, “From a famous blues musician. Just relax and listen to the music, while I monitor your emotions.”
“Sure thing,” Lucy said.
The music started playing. It was an odd sound; with various electric guitars that normally would’ve caused Lucy to recoil. However, the way they were played created a smooth, almost fluid listening experience. Lucy exhaled, letting her shoulders relax and her mind wander, lost in the smooth tunes. Every now and again Hayabusa would make a sound of intrigue. The session continued for several hours before Hayabusa turned off the gramophone.
“How are you feeling?”
“Good,” Lucy smiled. Her head felt a bit groggy, but she guessed that was just a side effect of sitting still and listening to music for half a day. “Really good. Relaxed, too. Like I just spent all morning taking a hot bath.”
“Okay, excellent. Your vitals reflect it, too. How about we break for lunch then get back to it.”
“Sure!”
The rest of the day passed uneventfully. Lucy got paid then went home. After storing her money and bathing, she crawled into bed. While she fell asleep quickly, Lucy found her dreams to be restless. They started out normally enough. Lucy was in a room filled with smoke. A man was sitting next to her, his arm around her waist. As the night went on and they talked about...Lucy wasn’t sure what they were talking about. The words were hazy, as if she wasn’t entirely hearing them. Eventually, the man kissed her. Lucy closed her eyes and fell into the kiss, a heat running through her body.
However, when Lucy opened her eyes, she saw the man had changed. He was no longer human. Rather, he was a demonic entity clothed in shadows. He pushed Lucy down and caused her clothes to vanish in a flash. Then, he started fucking her. At first Lucy was horrified, writhing beneath the demon’s weight. But as the night went on, she began moaning in pleasure. The demon was driving her past what she’d expected to enjoy, into a realm where only primal degeneracy existed. And Lucy loved it. Soon her writhes of discomfort morphed into hungry, sexual movements. The demon reciprocated, and as he came Lucy gasped and woke up. It was early morning and her bed was a complete mess, the covers tangled around her form. She reached down and felt her crotch. She’d clearly orgasmed several times in her sleep.
The dream was on Lucy’s mind as she walked to work. Hayabusa was pleasant and they exchanged small talk as Lucy got ready for another day of experimentation. “Hey,” Lucy said, “Are there any...”
“What’s wrong?” Hayabusa asked with genuine concern.
“N-never mind,” Lucy said. She felt embarrassment over her dream, and a sudden desire not to discuss it with a stranger. Lucy relaxed and listened to the music Hayabusa played.
The experiments continued for nearly a week. Each time Hayabusa would kindly help attach wires to Lucy, then play gentle music and record Lucy’s reactions. Lucy found nothing odd in the sessions, but when she slept her dreams would be plagued with erotic experiences. Heavy metal would blare as a demonic entity stripped Lucy naked and ravaged her. What was most concerning to her was that Lucy enjoyed the dreams. She’d wake up with her panties and pajama bottoms soaked. After nearly a week, Lucy decided that she’d need to confront Hayabusa over the strange dreams.
“Hey, Hayabusa,” Lucy said. The doctor looked up at her with a smile. “I need to report a strange side effect.”
“Oh?” Hayabusa asked, “What’s happening?”
“Every night, I have these really strange dreams,” Lucy said, “I get attacked by this evil being. It’s almost demonic.”
“Is heavy metal playing?”
Lucy froze. Her brow furrowed as she realized that Hayabusa knew something about the dreams, more than he ought to have known unless he’d expected the dreams to occur. Lucy stepped back defensively. “How would you know that?” Lucy asked.
“’Cause that’s what the magic is designed to do,” Hayabusa said, “Get a girl all nice and excited before I make my move.”
“Who are you?” Lucy asked. She quickly wished she hadn’t asked. Hayabusa let out a loud, rhythmic wail. Purple magic surrounded his body. At first it morphed his clothes, causing his labcoat and shirt to disappear, leaving him clad in heavy boots and tight black pants. Then, his skin changed. It turned a pale gray color, and a tattoo that read “Skeleton” appeared over his chest. “You!” Lucy gasped, recognizing the man.
It was Vidaldus Taka, the assassin from Trinity Raven that had attacked her in the tower of heaven. Lucy swore and jumped into a fighting stance as Vidaldus shook his head, his tongue lashing about before settling. Lucy reached for her keys. “You bastard,” Lucy said, “I don’t know what you’re playing at, but it’s not going to work.”
“Oh? Haven’t figured it out yet? Let me tell you then,” Vidaldus laughed, “I’m here for you!”
“Me?!”
“Hell yeah, babe,” Vidaldus said, “After you and that water-magic bombshell beat me in the tower of heaven, you’re all I’ve been able to think about. You ended my career as an assassin, so now I’m going to end your career as a mage by turning you into one of my loyal, rockin’, succubus slaves.”
Lucy’s brow furrowed. “As if,” she said, “Get ready, creep. I beat you once before and I’ll do it again.”
For a few moments, Lucy was surprised to see Vidaldus confidently smiling, making no motion to attack her or flee. However, Lucy eventually realized that she hadn’t drawn her keys. When she looked down, she was shocked to discover that her hand hadn’t gone to her keys, nor to her whip, but had found its way under the front of her skit. She gasped, suddenly realizing that she was rubbing her clit through her panties. She tried to stop, but her hands wouldn’t budge. They continued their actions, unbothered by the enemy leering in Lucy’s direction. “W-what did you--”
“You think I’m dumb enough to rush to fight twice?” Vidaldus asked, “Hell no. That music you’ve been listening to for days now wasn’t some random tunes. It was a variant version of Rock of Succubus! Not enough to fully enslave you, but more than enough to keep you nice and docile for me to do the job myself.”
“N-no...” Lucy gasped, unable to move. She watched in horror as Vidaldus retrieved his guitar from behind a table. He tuned it slowly, clearly reveling in the terrified expression on Lucy’s face and the tears running down her cheeks. “Please, don’t. I--”
“Too late, babe,” Vidaldus said, “Get ready, cause your rockin’ new life is about to begin. Rock of Succubus!”
The guitar burst to life as the spell erupted. Lucy screamed as the magic engulfed her, ripping apart her mind and sending her to a place of heavy metal bliss.
-----
To Vidaldus there was nothing better than watching a girl getting turned into a succubus. There was something about the scene that just excited him. Maybe it was the way their screams always seemed to synchronize with the heavy metal riffs played by the Rock of Succubus spell. Or maybe it was the intense flow of dark magic that enveloped the girl, coating them in sickly purple light. Their bodily contortions were also pretty sexy as far as Vidaldus was concerned. And it helped that this wasn’t some random groupie he’d found. It was that bitch Lucy who’d defeated him before. Vidaldus’s heart raced as he saw months of careful plotting pay off as the spell finished.
Lucy stood with pale gray skin, her hair loose around her shoulders. She grinned widely, showing many of her teeth. Her clothes were gone, replaced with a small, leather, purple top that showed off her cleavage and stopped just above her navel, clinging tightly to her flesh. Her bottoms were a pair of tiny denim shorts, the bottoms frayed and the top held in place by a gold-loop belt. Her legs were clad in black fishnets and her feet in spiked leather boots. Studded leather bands wrapped around her wrists and a spiked leather collar coiled around her throat. And below her navel was a gothic tattoo, marking her as a slave to the Rock of Succubus. She stared at Vidaldus with wide, red eyes, then cheered. “Fuck yeah, you were right, Master! Being a succubus is way better than being some dumb Fairy Tail mage.”
“Yeah! Now that’s what I like to hear, baby,” Vidaldus cooed. He lowered his guitar, then placed it on the table. He approached his newly succubized slave, taking in the sight of her. He found it exhilarating, seeing the bombshell blonde painted in his colors, clad in the clothes he thought most fitting for her. There was still a chance her willpower could dispel his magic, but it was a longshot. Even still, Vidaldus knew he’d need to work quickly to complete his spell. He stopped in front of Lucy and looked down into her eyes. She beamed at him with a sinister brow and confident grin. Then, without warning, Vidaldus coiled a hand around her waist, pulled her close, and claimed her mouth. He could feel Lucy’s surprise as her lips parted for him. But as his tongue slithered into her mouth, he felt her understand. Lucy pressed her body against his, placing her hands on his chest and rubbing her hips against him. Vidaldus felt excitement begin to boil in his crotch, anticipation as he explored Lucy’s mouth with his tongue. After over a minute had passed he broke the kiss, pulling his head back and meeting Lucy’s eyes. Drool ran from her still confident lips, and she looked at him with a readiness to continue with whatever he wanted.
“Alright, babe,” Vidaldus said, “Here’s how things are going to work; in order to use my magic again, you’ll either need to break free of the rock or I’ll need to complete the spell. And hell if I'm about to let you break free. Which means you better get ready for some intimacy.”
“You don’t need to tell me twice,” Lucy said. Moments later her hands were on her belt, pulling it loose. She pulled her shorts down past her thighs, revealing the tight black panties Vidaldus’s magic had given her. Vidaldus saw the moisture causing the fabric to cling to Lucy’s pussy. He grinned as she tugged them down, revealing a pink slit amidst pale flesh. Her boots and fishnets went next, followed by her top. Vidaldus nearly stopped stripping himself to grab at Lucy’s massive tits. If he’d been less concerned about her breaking free he might’ve allowed himself the time to indulge. But this girl had already beaten him once. He wasn’t going to risk it happening again.
Vidaldus shoved all the equipment from a metal table, then threw Lucy onto it. He grinned as he pushed the woman onto her back, grabbing her pale thighs and prying them apart. While the spell had turned most of Lucy’s skin into shades of gray, her pussy was still a bright pink slit. Vidaldus grinned and shoved his erect cock forward, pressing against Lucy’s entrance. She uttered a sound somewhere between a moan and a laugh as Vidaldus slid his cock up, over her pussy, and let it rest covering her clit and her pubic area. He’d honed his spell to make sure it would eliminate any body hair on a succubized woman, leaving them nice and smooth for him.
“Woo, okay, Lucy. Seems like we’re about ready to start rockin’ our hips back and forth all night,” Vidaldus said.
“Hell yeah!”
“You a virgin?”
“Damn right. You’re going to defile me fir—Ah!” Lucy stopped and put a hand on her head. Vidaldus recognized this. While Rock of Succubus was powerful, Lucy was only subject to the first phase of it. Remnants of her old personality were still offering resistance. “Shit, Master, I’ve got this annoying voice in my head screaming at me to fight you or run away.”
“It’s normal,” Vidaldus said, “But don’t worry. I’ll shut her up for good, soon.”
“What do you mean?”
“Oh, never got the chance to mention is back at the tower of heaven,” Vidaldus grinned, “But my magic has several parts. First is just changing a girl into a sexy, rockin’ groupie. Once I have her alone and get all up-close-and-personal, my magic will extract all the boring parts of her personality.”
“Get the fuck out,” Lucy asked, her eyes wide, “You can stop this annoying voice screaming at me to run?”
“Damn right I can,” Vidaldus said. He patted his cock against Lucy’s entrance. “All I gotta do is finish inside you and you’ll be unable to break free on your own. You’ll be my succubus slave for as long as I’m living free.”
“Then what are you waiting for?” Lucy asked. She bucked her hips in such a way that she nearly impaled her pussy on Vidaldus’s waiting cock. “Fuck me already! That way we can start rockin’ for real!”
“Ha! Let’s get it on, then!”
There was a long pause as Vidaldus realigned his cock with Lucy’s entrance. She was already wet. Vidaldus probed her entrance, grinning as he felt his tip beginning to slip in. He braced himself and pushed it in. Lucy’s walls showed resistance, but once he’d forced them open is cock began sliding through her wet folds with ease. Vidaldus’s rear clenched and he nearly blanked out as the pleasure of forcing his way inside Lucy’s virgin hole nearly overpowered him. The only thing that kept him focused was Lucy, who was chanting, “fuck yeah, fuck yeah, fuck yeah fuck yeah!” with increasing excitement as he continued to push into her.
“Fuck, virgin Fairy Tail girls are something else,” Vidaldus thought, squinting through the pleasure as he pushed deeper and deeper into Lucy.
“Ah,” Lucy gasped as Vidaldus’s cock hit her deepest point. She tried to gulp down air, but it was clear she was experiencing a variety of mixed pleasures and emotions. Vidaldus couldn’t help but laugh as he held his position, letting things sink in for Lucy. After a few moments, he grew bored and leaned down over her. Lucy blinked in surprise as Vidaldus claimed her lips, his hands digging into her breasts. Vidaldus pushed his tongue into Lucy’s mouth and she moaned against it, her hips pressing into his. Lucy’s back arched and she wrapped her arms around Vidaldus’s neck. Slowly, Vidaldus began pumping his hips. He felt Lucy’s moans shift to euphoric laughter as he began fucking her, plowing her virgin pussy. It continued like this for a few minutes, their bodies and tongues locked in a carnal dance, before Lucy made a sound of pain. Vidaldus pulled back and saw Lucy’s eyes closed in pain. “Shut up!”
“Voice again?” Vidaldus asked.
“Fuck, Master, her voice is louder than ever,” Lucy said.
“Then we’re going to have to drown it out,” Vidaldus said, “With pleasure and rock!”
“Hell yeah!”
What followed was something Vidaldus considered a finishing move. He started singing heavy metal lyrics as he pumped his hips in time with the lyrics. Lucy quickly caught on, and pushing away the feelings of resistance began slamming her hips in unison with Vidaldus, the slapping creating a sort of drumbeat for their demonic song. It wasn’t long before Lucy came. Vidaldus watched the woman lose the beat, her hips bucking wildly as her eyes went glassy. It would be a blow against the parts of her trying to resist, like if somebody had cast a flashbang spell. But for Vidaldus, it was license to push even harder. Soon Lucy was in the constant throes of pleasure, her voice a chain of long screams complimenting Vidaldus’s. He pushed her until she was drenched in sweat and struggling to keep up. Her red eyes showed nothing but desperation. And Vidaldus knew the resistance had been subdued. It was time to complete the spell.
“Fuck, I’m close,” Vidaldus said as he quickened his pace, slamming his hips into Lucy.
“Do it, Master! Fuck me into submission. Make this dumbass voice stop screaming at me to resist!” Lucy cried, her eyes nearly squinting shut as her body coiled around Vidaldus’s girth, desperate for his seed. The tight feeling of her pussy drove Vidaldus closer to his orgasm. He grabbed Lucy’s hips as his cock swelled. With a final deep thrust and a grunt, he came in Lucy. She screamed in ecstasy, her limbs anchoring her to Vidaldus as she threw her head back. Her body developed a purple shroud of magic as Vidaldus continued, making sure to pour as much of his fluids into her womb to seal his control over the mage. When Lucy settled, Vidaldus pulled out and knelt beside her.
The purple magic cracked and cackled around Lucy’s body. After a few moments it began moving, coagulating over Lucy’s bountiful chest. The magic flashed as it compressed, turning into a black gemstone and settling atop Lucy’s torso, just beneath her collarbone.
Vidaldus plucked the black gemstone from Lucy’s chest and held it before his face. He grinned. “How does it feel, blondie?” he asked, knowing the scraps of Lucy’s original personality could still hear him. “You’re barely even a person now. Rockin’, right? My spell splits off any part of a person’s personality that involves autonomy or free will, along with about twenty-five percent of their magical energy. You’ll still be conscious, but you won’t be able to do anything but watch as your body serves as my rockin’ succubus slave.”
The gemstone vibrated, as if there were somebody trapped inside, banging their fists against the walls of their crystal prison.
Vidaldus laughed, then strode over to his guitar. He picked it up by the neck and spun it around. He pressed the gemstone into the base of the guitar, grinning as it molded into a little groove. It flashed, then fused with the guitar, staying in place. “That should give you a rockin’ good view,” Vidaldus said, “And if I ever need an extra boost of magical energy, I can just take from you.”
The gemstone was silent. Vidaldus positioned the guitar against the table, it’s front facing Lucy’s body. Vidaldus approached and loomed over his prize. He placed a foot on Lucy’s chest. The succubus blinked her eyes open and looked up at him, an excited grin on her face.
“You’ve become a real succubus slave, haven’t you?”
“Fuck yeah, Master.”
“But Lucy sounds like a shit name for a succubus,” Vidaldus said, “From now on, your name is Lulu the Rockin’ Sex Slave. You’re going to be a horny slut who pleases me whenever I want. And you’ll also help me conquer that other Fairy Tail girl with the water magic and the rockin’ bod.” Vidaldus pressed his foot harder into the succubus, eliciting a needy moan. “What do you say to that, slave?”
Lulu stared up at Vidaldus with perverse excitement in her eyes. “Sounds like a rockin’ good time, Master.”
