Make them my slaves, of course!

Smiling triumphantly at the feeling of having ensnared these two sensational sisters, you gently ask their slumbering bodies, "Mirajane... Lisanna... Can you hear me?"

Continuing to sway in time to the lullaby you'd long stopped playing, both girls, in a voice distant, dreamy, and content answered, "Yes... I hear you..."

"Good girls. Now tell me honestly... Do either of you have anywhere to be today?" It was important no one disturbed you while enslaving them, so you felt it would be good to make sure nobody was going to show up unannounced looking for them.

"No," Mirajane replied after a couple moments, probably still unsure if she should tell a man she'd only just met her plans, "Today is my day off. After Lisanna and I finished shopping, I planned to go home and relax..."

"I was just going to practice with whatever instrument I bought..." Lisanna added with less ****.

"Good girls. Did you enjoy listening to my song?"

"Oh yes..." Mirajane admitted, the smile on her sleeping face growing warmer from thinking of the relaxing music, "It felt so good... made me feel so sleepy..."

"I loved it..." Lisanna admitted with a slight reddening of her slumbering face, "I feel sooooo relaxed... I feel sooooo safe... feels sooooo good to feel this way..."

"Good girls. Now tell me, would you like to hear me play some more?"

"Yes... please..." The sisters pleaded, lifting their heads up slightly as they did, "I love the sound of your music... I want to hear more... I need to hear more... I must hear more... I'll do anything to hear more..."

The desire in their begging was enough to make your cock harden with anticipation, but you knew you couldn't rush this. Despite their claims of being willing to do anything in exchange for hearing more music, you knew what would happen if you tried to exploit that without taking the time to properly deepen their trance: The shock of your requests would instantly snap the two out of the trance, leaving you at the mercy of a S-Class mage... not to mention what the rest of Fairy Tail and the Magic Council might do to you afterwards! So instead of indulging your own desires, you chose to grant the girls request for another song.

So you began playing a far more energetic and intoxicating melody than the lullaby from before, with flowing highs and sudden lows that made the two sisters shiver ever so slightly, before slowing to a steady pulse that really got their bodies to react. Rising points in their tops hinted at their nipples growing erect, the sound of their hearts pounding mixed in with your melody, and before long a faint moan escaped their lips.

"This music feels soooo goooood," Mirajane moaned as she pulled up her dress, allowing a hand to slowly stroke her crotch through the fabric of her panties. Once that hand was in place, she snuck the other down her top, gently teasing her own nipples as her face turned bright red.

"Makes me feel sooooo sexy..." Lisanna dreamily panted as she too snaked her hands under her skirt and up her top, though unlike her sister, Lisanna quickly began tweaking her nipples and sticking a finger into her pussy, clearly desiring a swifter release than Mirajane did.

As the snow-haired siblings masturbated to the rhythm of your sensual sonnet, you too couldn't resist growing harder and harder alongside them. This transferred into the music, upping the tempo and further increasing the sexual frenzy the two Fairy Tail mages moved under. Soon the song reached a crescendo, immediately joined by the blissful cries of Mirajane and Lisanna, sinking to their knees as they squirted their love juices onto the floor. You took a moment to compose yourself, the excitement in seeing the sisters' climax having caused you to stain your pants with sexual fluid. Once you had though, you resumed playing the flute, knowing that with their orgasm the Strauss sisters minds were empty vessels ready to be filled with your wishes and desires.

This third song was a similar to the music beautiful women would dance to in the palace of a rich noble, a beat to which their bodies would move erotically to so as to arouse their patron. Furthermore, in contrast the previous songs, which only transmitted feels, this song subtly spoke commands to the entranced sisters, "Dance. Obey. Submit," over and over, brainwashing the two to become your desired slaves. As a result of this tune, Mirajane and Lisanna slowly rose from their kneeling position, their bodies already beginning to sway ever so slightly in time with the melody. Once the two white-haired lovelies were standing straight, they eagerly embraced moving their hips and breasts erotically, much to your delight.

"This music is wonderful..." Mirajane swooned as she placed her hands behind her head, thrusting her chest out as she let her boobies sway side to side almost hypnotically. "I need someone to dance for... I need someone to obey... I need someone to submit to..." Her mind, having been weakened by the orgasm, showed no resistance to the new desires being implanted.

Lisanna, in contrast, used her hands to jiggle her breasts while shaking her butt and hips enticingly, "I love being a sexy dancer... I love obeying my master... I love submitting myself to my master..." Her resistance having been weaker than Mirajane's meant Lisanna was already far more brainwashed than her big sister.

As the two babes danced, their minds dreamed about the new desires that were becoming a part of their very being: they imagined that they were sexy dancing slaves, putting on an erotic show for their shared master, competing for the honor of being the first their master would bed tonight. As the two did, they began to softly chant, "I am a ****. A **** loves her master. A **** must obey her master. A **** must submit to her master." With each chanting of their mantra, the next grew louder as it became more and more a part of who they were, until they were chanting it with excited glee at the top of their voices.

Once the sensual sisters' chanting reached its peak, you stopped playing, knowing that the brainwashing was complete and that the Strauss sisters were ready to serve you. Even when you stopped, the two enslaved siblings continued to chant and dance until you commanded them, "Stop." They obeyed instantly, awaiting your next command. "Listen closely, Mirajane and Lisanna. The things I am about to tell you are the absolute truth: I am your master and you are my slaves. You have always wanted to be my slaves. You came to my shop so that you could offer yourselves to me as my slaves."

"Yes... You are my master and I am your ****... I have always wanted to be your ****... I came to your shop to offer myself to you as your ****..." The brainwashed beauties repeated, their minds altering their own memories to justify your commands.

"In a moment, I will command you both to awaken. When you awaken, you will have no memory of being enchanted by the flute. You believe you became lost in the music. When I discuss the price, you will offer yourselves as my slaves. You will believe this to be your own idea."

"Yes Master... I will wake with no memory of being enchanted... I became lost in the music... I will offer myself as your **** for the flute... This will be my own idea..."

"Good girls," you praise, making your two thralls smile slightly before commanding them, "Wake up. ...So ladies, what did you think? Did the flute sound like something you'd like?"

The moment you commanded it, the two opened their eyes, their time under your spell forgotten except what you'd instructed. Lisanna immediately blushed thanks to her newfound desire to submit to you before stuttering, "I-I-it was beautiful! I completely lost track of time listening. Are you sure you've never played before?"

"I swear I've never even had a lesson. The flute's magic makes anyone an expert with it in their hands. So, I take it you two would like to purchase it then?"

"Oh yes," Mirajane replied with a confidant, seductive smile, convinced you were the one to satisfy Lisanna and her implanted need to submit, "Now, I don't believe you ever mentioned the price, did you?"

"No, no I did not my dears," You say with confidence, making the Strauss Sisters blush slightly, "Now that you know the hype is real, tell me: what would you two offer for my flute?"

The snow-white sisters shared a knowing, eager look, with Mirajane taking hold of Lisanna's before seductively declaring, "We'll give you us."

"Oh?" You question, pretending to be surprised by this declaration, "And what exactly do you mean by that?"

"It's quite simple really," Mirajane replied, "In exchange for the flute, my sister and I will become your slaves. You will own us in body, heart, and mind. Any command you wish to give, we'll gladly obey, for as long as you want."

"You see," Lisanna elaborated, "My sister and I have always wanted a master to submit and obey. Someone who will command us and let us embrace our desire to submit absolutely."

"Of course," Mirajane added, "We don't want just anyone to be our master. We want someone who will treasure and care for us, and you seem like a man who would fit that bill. So what do you say, do we have a deal?"

You decided to tease them just a little, "I hope you two understand, that if you become my slaves, everything you own will belong to me, correct? If that's the case, the flute would still be mine. Is that alright with you two."

"Yes," was their immediate response, clearly hoping you were interested in their offer.

Smiling perversely, you felt no need to prolong their wait. Putting the flute away, you ordered, "Follow me upstairs to the bedroom. I intend to thoroughly inspect the two of you. That's my first order as your master."

"Yes Master!" The Strauss sisters replied with glee as they followed you up to your bedroom, both clearly aroused at not only having their new lifelong wet dream fulfilled but from your commanding tone.

Seating yourself on the bed, you face your beautiful new thralls and commanded, "Strip."

"Yes Master." Lisanna immediately tried to pull up her shirt, only for Mirajane to stop her before playfully chiding, "Lisanna, I think Master expects us to make a show of this. Why don't you let me go first as an example. Is that alright with you, Master?"

"Very well."

Having received permission, Mirajane had her little sister stand off to the side before beginning a seductive striptease. First, the poster girl of Fairy Tail skillfully unlatched her bra and pulled it up through her top, giving it a twirl before playfully placing it in your lap. Then in a fluid motion, she took off her dress, briefly dancing with it as though it were a ribbon as she kicked off her shoes and socks. Finally, she removed her panties whilst making sure to bend in such a way that you got a generous view of her cleavage, then presented her undies like they were a gift.

Taking and briefly sniffing the offered panties, much to Mirajane's delight, you said, "Very sexy, Mirajane... I have to wonder, have you done this before?"

"I have put on a show like that for others," Mirajane honestly answered, "But I can assure you I've never slept with anyone before in my life."

"I see," You then turned your attention to Lisanna, "Now it is your turn. Show me your best."

"Yes Master!" Lisanna replied as she put on her own strip show, imitating what she'd seen her big sister do. It quickly became clear that Lisanna had no experience, making her movements awkward and jerky. Still, it was also clear she was trying her best, removing her bra and panties before taking off her top and skirt.

So now you had two beautiful thralls standing before you naked while their bra and panties sat in your lap, both fidgeting slightly as they clearly enjoyed your eyes wandering their nude bodies. "Pose for me, my lovely slaves." You enjoyed watching the two assume different poses that showed off the erotic features of their bodies, as you wondered which of them you'd deflower first...
