> Be Anon, somewhat successful novelist
> Your old friend, a high school principal, asked you for a favor
> As it happened, she had three graduates with an unusual background, and she wondered if you couldn't find them something to do while they figured out things
> At first they were a pretty gloomy bunch
> Something about losing their voices at the battle of the bands
> You gave them some simple chores, Housekeeping for Sonata, cooking for Aria, and minor secretary work for Adagio
> It seemed giving them something to do helped
> Before long, they began opening up to you, telling you bits and pieces of their history
> If it weren't for the events of last year, you wouldn't have believed them, but now portals and magic are part of the world
> Over the past two months you have noticed some oddities, though
> Nothing magical, just some quirks they seem to share
> Whenever an argument ended, one of them, usually Sonata or Aria, would turn away
> At first you thought it was childish stubbornness, but their expressions were a little off
> Dissatisfied rather than angry
> Something about that brought another thing to your attention
> Adagio tended to take memos with her back to you
> She was also acting increasingly frustrated
> And so, today, you decide to get to the bottom of the matter
> You wait until Sonata is busy tidying your room, and Aria is cooking breakfast
> You find Adagio going over your day planner in your study
> You serruptitiously close the door behind you
> She looks up at the sound
> "Ah, Mr. Mous. Is there something I can help you with?"
> It's always a little strange to get such a respectful tone, when she is so domineering with the others
"Yes, I was hoping you could explain something for me. Is there a reason why your friends always turn away when you get done arguing?"
> She chews her lip, then sighs
> "You remember how we told you we used to be..."
"Magical hippocampi? Sirens, I think?"
> She nods
> "We have an...inborn trait? A custom? Something, where you assert and confirm dominance with anal penetration."
> You feel blood rushing to your cheeks, and other places
"Anal penetration? Really?"
> Adagio looks serious though
> She frowns
> "Yes. In our old forms, we had an organ that jutted out, for egg laying purposes. We only deposited eggs in the males' pouches, but it was pleasurable to stick them other places too. Sadly, there doesn't seem to be anything like that on the human body, and it's been quite frustrating."
> Kinda like seahorses, you guess
"And the eggs are fertilized within the pouch, right?"
> She nods, her eyebrows raised in surprise
> "Is there something similar to sirens in this world?"
"Uh, seahorses. They're pretty small, but they mate the same way. Humans sort of have the opposite though. Males have a jutting organ that fertilizes the egg inside the female."
> Adagio's brow furrows
> "Then females are not the dominant gender here?"
"I would say there isn't a clear cut dominant gender, but we don't even have a custom like what you described. I mean,  women can penetrate others if they have a strap-on, but it's more of a sex thing, in an oblique way."
> Her eyes light up 
> "Could we get strap-ons?"
> ...
"I...guess? Do you really need them?"
> Adagio shifts uncomfortably
> "It's hard to explain. When you don't confirm dominance, it's harder to get along. Sonata doesn't pay attention as well as she used to, and Aria tries to fight me over every little thing. I, myself, have been struggling with taking orders from you."
"Really? You always seem very respectful."
> She gives you a pained smile
> "Thank you, but even now I want to order you to buy us these strap-on things, even though we are living in your den, eating from your bounty."
> A thought occurs to you
"So you would be happier if I..."
> Adagio shakily sets aside your planner
> "It would be very helpful."
> She stands hesitantly, and turns her back to you
> You approach slowly, wondering if you are just playing to an elaborate lie
> Still, she is quite an attractive young lady
> You stand behind her and reach around to unbutton her jeans
> The floral smell of her hair is inescapable, even as your trembling hands drag the zipper down
> You slide your hands along her hips, pushing her pants and panties down
> You gaze fixedly at her pert rump as you free your erection
> Her breathing quickens as you press between those tender cheeks
> It feels good, however...
"Ah, I'll need some sort of lubrication. It's kinda dry down there. Here, "
> You push three fingers into her mouth
> She makes a muffled protest, but doesn't move to stop you
> Her tongue slithers against them for a moment, then lies still
> Your erection is now painfully hard
> You bring your wet fingers to your dick, slathering it with her saliva
> Just to be safe, you dip your fingers in her hot mouth once again and likewise lube up
> Thusly prepared, you place one hand on her collarbone and the other hand on her pelvis
> With a rock of your hips, your cock plows through her pillowy cheeks and comes to rest at her back door
> Adagio breathes in uneven little gasps
> You press down on her pelvis, and thrust slowly into her anus
> She whispers in her low, throaty voice, "Oh, oh yes!"
> Spurred on, you develop a steady rhythm as she writhes against you
> You grunt in pleasure at the tightness of her passage with each thrust
> Your hand wanders from her collarbone, sliding down to cup her petit breast
> You're probably going beyond the bounds of Siren tradition, but she isn't protesting
> Rather,
> "By the seven seas, Mr. Mous!"
> She pants heavily, her nipple hard under your thumb
> Waves begin to gather within you
> You press your chin down on her shoulder, groping for leverage as you thrust frantically into her 
> She spasms under your hands, earnest, persistent contractions milking your embedded cock
> She lets out a low keening wail of ecstasy
> Your member surges within her, pleasure and cum flowing into her ass with the strength of the tides
> She leans against your chest, her chest heaving from the experience
> You embrace Adagio around her stomach and let out a long sigh
"Feel better?"
> She tilts her head to look at you
> Her expression is more relaxed than you have ever seen
> "Much."
> With a sharp exhale, she straightens and begins pulling her pants back up
> You tidy yourself up a bit as well
> It takes her a moment to focus, but she picks up your planner again
> "So, back to business. What shall I put in today's schedule?"
> Her smile is bright, her expression, attentive
> Is it your imagination, or was her normal attitude more subdued?
> Well, no matter
"After breakfast, I have some purchases to make. In that time, you shall research strap-ons and lubricant, and teach your friends about this matter."
> Adagio bows her head gratefully
> "As you say, Mr. Mous."

> The lady at the register of the shop was very helpful, even if she came to some rather wrong and embarrassing conclusions

> It took some getting used to, what with the strap-ons under each girl's clothes
"It's like I'm living with three traps!"
> Sonata just tilted her head in confusion
> What followed was an hour long explanation that was probably futile
> Still, you believe part of why she seems so...dumb, is because no one took the time to clearly explain things
> Then there were the times when the girls actually used their new toys
> They were never really shy about it, but it was shocking the first time you saw Aria lift up Sonata's skirt and plow her ass
> Adagio seemed to have shared some of your techniques from your session, so you got quite a show each time
> You did see results, though
> Sonata did seem to have a much longer attention span, and Aria was usually only apathetic, rather than sullen

> As time went on, you gave each of them more duties
> What had been something of a charity case soon became a productive arrangement, even ignoring the titillation
> One afternoon, you smelled something good in the kitchen

> You walk in to find Aria frowning at the inside of the fridge
> Perhaps some grocery shopping is in order
> You track the smell to the oven, and open the door
> "Stop!"
> The puffy pastry collapses
> You serruptitiously close the oven door, and turn to face an angry Aria
"Sorry about that. Souffles, though, I am quite impressed."
> "Don't try to flatter your way out of this one, Mr. Mous. Now I have to start all over again.", she growled
"Isn't it still good though? I mean, puffy souffles don't actually taste any different than fallen ones."
> She advances on you with ire flashing in her eyes
> "I'm trying to get it right in time for the next time you meet with your editor. Do you want to serve flat souffles to your editor?"
> You grimace
"Ah, I am truly sorry. I do appreciate what you are doing to help, and you really have become a great cook."
> She frowns in dissatisfaction, then huffs
> You give her a nod, and turn to leave the kitchen 
> You pause at the transition between the kitchen and the dining room
> Maybe you should get some sort of gift for your editor?
> The foreign sales of your last novel are doing rather well, and-
> A pair of hands roughly pull your pants down
"Hey!"
> You start to turn, but an iron grip grabs your throat, keeping you off balance
> Then something slick and firm probes your rear
"Hey, woah, I-"
> Aria presses up behind you, her breasts mashed against your back, her strap-on pushing slowly past your puckered anus
> "The kitchen is my domain, Anon E. Mous. You may provide for us, but you must respect my role in our little group."
> Her voice is a soft growl, almost tender
"I'm-"
> It feels so weird, you feel like your guts are twisting at the persistent prodding
"I'm not a siren!"
> She nuzzles her face against your shoulder blades
> "Oh, I know. That's why I'm going to be so understanding."
> A slender hand slides across your hip and grasps your manhood
> At that moment, to your shame and confusion, you realise you have an erection
> That supple hand, still slick from applying the lube, gently strokes your rod in time to the stuttering progress of the strap-on up your ass
> Aria loosens her grip on your neck, changing it to strange, rhythmic stroking 
> It's like she's trying to massage the front of your neck, but there are so many competing sensations, you are starting to get your wires crossed
> She finally hilts inside of you, her firm body fully pressed up against yours
> "I know you watch us, and not just to keep track of who is on top."
> Aria keeps her strokes slow and steady, a tingling heat building inside you
> She slides her hand up your shaft, her thumb flicking back and forth across the ridge of your head
> "You get off on it, don't you?"
> Her pace quickens, and you groan at the stimulation
> She playfully nips at the skin of your back
> Your hands grasp at air, twitching
> Aria's hand on your throbbing manhood blurs up and down
"Fuck!"
> Cum splatters on your shirt, on the floor, and drips down onto Aria's hand
> At last, the firm rod slides out of your rear
> You twitch at that, and Aria pulls away
> You are sore in ways you have never been before, but...
> You slowly turn around to find her retreating into the kitchen, examining her hand with distaste
"Was that really called for?"
> She gives you one of her rare smiles
> "I was within my rights... and I wanted to. Besides, you enjoyed it, so it's fine."
> Damn her, but she's right
"I'll get you back sometime. You know that, right?"
> Her smile turns sly
> "I'm counting on it."

> The meeting with your editor went well, though the girls felt a little odd to have to go without their prosthesis for the visit
> Weeks passed
> Adagio dresses in pantsuits almost every day now, she even bought herself a desk and screens your calls
>  Aria has developed an almost fetishistic obsession with aprons and cooking
> You aren't even allowed inside the kitchen except to deliver groceries
> As a compromise, she leaves pitchers of water and platters of food out for your inevitable snacking urges
> Sonata...
> You have begun to worry about Sonata
> Laundry and housekeeping only take up so much time
> She gets rather lonely while Aria bustles about her kitchen kingdom and Adagio buries herself in finances and scheduling
> You occasionally get Sonata's feedback on a manuscript, but there are many days when you don't have much for her to do
> She has developed a habit of watching you each morning as you get dressed
> It wasn't so long ago that you would be embarrassed by her gaze, but you suppose you have become more siren-ish in your sense of modesty
> Still, it's a little odd
> One cool summer morning, you feel the bed shift under someone's weight
> You open your eyes to see Sonata's face flushed and very close
"Uh, good mor-"
> She presses her lips against yours
> It's nice, but she doesn't move her lips or anything
> You push the tip of your tongue out between your lips, and she squeaks when it touches hers
> Sonata pulls back, a confused look on her face
> "W-was that your tongue? For realsies?"
> You sit up, laughing a little
"Yes it was. Now, what can I do for you this fine morning?"
> She looks at you with determined eyes
> "I've figured it out. Adagio helps with book stuff, Aria with food, and I..."
> A light blush dusts her cheeks
"Yes? Those are their duties..."
> Sonata's hands clench in her skirt
> "I clean, and give you children."
> ...
> You just stare at her, trying to make sense of it all
> She stares down at her lap
> "It's all I'm good for."
"Sonata..."
> What can you say?
> "I'm not smart, or ambitious, or anything. Anybody can clean. I'm nothing special."
> You pull her into an embrace, overwhelmed with pity
"That's not true, we just haven't found what you are good at."
> You rub her back, and she sniffles against your chest
> You sigh
> She's always been the lowest in the pecking order, as far as you can tell
> And she is right, she isn't remarkably intelligent, or ambitious 
> You gaze down at her, idly appreciating how well tailored the maid uniform is to her slim waist
> ...
"Hey, Sonata, I want to check something."
> She wipes her eyes on your shirt, then sits up
> You walk over to the bathroom scale and step on
> She trails behind, uncertain
> You grimace at the reading
"I think Aria is getting too good at cooking."
> You heft the slight bulge of your stomach
> Sonata chews her lip
> "Um..."
> You step off the scale and face her
"How would you like to be my exercise buddy?"
> "I don't know that much about exercising..."
> You lay your hands on her shoulders and look her straight in the eye
"You don't have to. Your job is to make sure I exercise regularly and keep me company while I work out. Can you do that for me?"
> Her eyes fill with the subtle glow of hope
> "Yes, I can do that for you, Mr. Mous. You can count on me!"

> Something is wrong with the world when a grown man can't play video games late into the night in his own home
> Admittedly you only intended to play until midnight, but video games aren't meant to be cut off so arbitrarily
> The long and short of it is, you are not getting up no matter how hard Sonata shakes you
"L'v me alnn."
> She sighs
> "Come on, we need to run~."
> You grunt
> ...
> "You asked for this."
> Whatever
> You hear some rustling cloth
> In spite of your exhausted mind, you try to figure out what she's doing
> Probably opening the drapes
> Then she yanks off the sheet covering you
> You flinch at the slightly cool air, but cling to your pillow resolutely
> Sonata climbs up onto your bed, and you begin to feel uneasy
> Then she tugs your pajama bottoms down, and it all clicks
"Okay, okay, I'm-"
> "Too late!"
> Dry sex toy barges up your crack
"LUBE! USE LUBE!"
> She pauses then
> "Oh, right. Heh heh. Stay right there!"
> Sonata scampers off, and you sag into the mattress
> Your mind goes fuzzy and you drowse for a few minutes
> You are jolted awake by the slick length of Sonata's toy making its second approach through the Fanniana Trench
> "Sorry about earlier, I haven't done this before."
> You try to relax as the tip penetrates your exhaust port
"Just take it slow, alright?"
> Wait
"You never did this to Aria or Adagio?"
> She lays her palms on your shoulders, shifting her weight
> "Nope, I was always the pouch. Um, they said that I should do stuff to make you feel nice. Do you even have boobs?"
> You inhale sharply as the strap-on plunges deeper
> Her weight is heavy on your shoulders, and you begin to suspect you like getting plundered by innocent girls
"No boobs, just a penis."
> "Yeah?"
> She leans back, inadvertantly hilting
> You gasp at the sudden movement, your pelvis rising to better accommodate the hard length inside you
> Each shift of her hips sends a curious sensation through your inward parts, and a fresh surge of arousal through your dick
> "Oh, I see it. Hmmm, how do I get to it?"
> She leans back a little more and barely grazes your balls with her fingertips
> "Er, that won't work..."
"Maybe if you lean forward and reach under?"
> She's cute and all, but you don't intend to spend all morning with a toy up your ass
> "Ooh, okay!"
> Sonata presses against you, warm and soft
> Her hand slides down and grasps your manhood, and gives it a squeeze
"Mmm, better."
> She giggles, then slowly rocks her hips back and forth
> Her hand keeps time, squeezing your shaft when she hilts
"Sonata?"
> "Yeah?"
"Stroke my dick, not squeeze it."
> "Oh! I knew that!"
> In spite of her clumsy efforts, you do find yourself growing more and more aroused
> Part of that is the cute little noises of exertion she makes
> "Okay, next comes the part where I tell you what you did wrong. Anon!"
"Unf, yes?"
> Those slow strokes are taking their toll on you
> You feel warm all over
> "You were supposed to go running with me! Even if you are tired!"
> Your fingers snarl in the sheets
"Got it."
> She pauses for a moment
> "For realsies?"
> You sigh
"For realsies."
> "Good!"
> She picks up the pace, and you grunt into your pillow
> Her hand cups your balls, then slides up the velvety length of your erection, then down again
> You thrust against her hand, savoring the unfamiliar touch
> Just as it gets good, she abruptly stops
"What?"
> Sonata carefully extricates herself from you
> "All done! You understand your place."
> You sit up in bed, not even hiding your erection
> You shift a little, adjusting to the suddenly empty again rump
"Didn't you end just a bit early?"
> She tilts her head
> "Um, no?"
> You stare at her, clad only in a T-shirt and some panties
> Your hand drifts down to your dick
"Could you do me a favor and take off your shirt?"
> "Okay!"
> You stare at her fulsome breasts and begin stroking
> She just smiles at you, watching your movements curiously
> Then she starts stroking her own length
> "So...what are we doing?"
> You can't tell if her imitation is more arousing or amusing
"Having a good time. At least, I am."
> She beams at you
> "I am too!"
> The door opens and Adagio sticks her head in
> "Need some help waking u-"
> She stops in confusion
> "What are you two doing?"
> She steps into the room uncertainly, wearing purple pajamas
> Sonata wiggles her hips and thus the strap-on in her hand
> "Having a good time!"
> Adagio eyes you, then the bed
> "You didn't cum?"
"Ah, no."
> She sighs
> "Sonata, why don't we all take a shower? I'm sure Anon would appreciate the chance to get closer to us both."
> "Okay!"
> You have the best secretary


> Adagio is unusually subdued when she transfers the call
> "It's Principle Celestia."
"Thank you."
> You lean back in your chair as Adagio walks out of the study
> The voice that comes from the phone is warm and familiar
> "Your secretary is very professional, Anon. Where ever did you find such talent?"
> You smile at the playful tone
"I have certain connections. How have you been these, what, four months?"
> "I am doing rather well. CHS keeps me busy, but most of the magical phenomena has quieted down. The students are really quite vivacious this year, I almost feel young by association. Speaking of which...how are the girls holding up?"
> You chuckle ruefully
"Sometimes I think that it was them who took me in. It's not just Adagio, secretary par excellence. In a month or two, I honestly believe Aria could open a high class restaurant, meanwhile Sonata has developed into an incredible personal trainer in just a few weeks. These girls are impressively driven."
> There is silence on the line for a moment
> "That's quite the glowing recommendation, Anon."
> You smile a bit sheepishly
"I suppose it is. I guess what boils down to, is that it's a good thing I'm not their parent. While they have developed into competent young women, I have grown more and more dependent on them. Well,  to answer your original question, they seem much happier and friendlier than before."
> "That is good to hear. I had had my concerns about how well they would adapt to normal life, but it sounds like things are going swimmingly on your end."
> You stifle a laugh at her choice of words
> "Anon?"
"It's nothing, I just remembered an amusing thing. At any rate, it's true, things are going well over here. I managed to write my new book in record time, thanks to them taking care of me. Oh, by the way, you should be getting a copy or two of my new book soon. Be sure to share it with Luna when you get it."
> "I'll be looking forward to it. Well, as much as I wish I could talk with you some more, I really should be getting back to my paperwork. It's been good catching up with you, give my regards to the girls."
"Will do. Goodbye, Tia."
> "Bye, 'Non."
> You put the phone in its cradle
> The door to your study creaks open
> Adagio leans against the doorframe, a fond smile on her face
> "Secretary par excellence, eh?"
> You swivel to face her
"I stand by my words."
> She takes slow strides towards you, sashaying with every step
> You raise an eyebrow at her advancing
> She circles behind you, her fingers trailing across your shoulders and neck
> Her voice is like molten honey, a deep, predatory purr underlying it all
> "With such high praise, why, I find myself wondering what other position I could fill."
"With talent like yours, I'm sure you can do anything."
> She leans down, her breath hot on your ear
> "We listened in on your phone call. Do you know what we have decided?"
"What?"
> Her hands tremble as she turns your head towards her
> You are surprised to find her blushing
> Adagio breathes rather heavily
> "We have decided to take you as our mate."
> With that, she kisses you gently on the lips, then pulls back with an expectant look
> "What do you say?"
> You stand up and hold her close, kissing her back
"Nothing would make me happier."

The End
