Butterfly Effect of a Siren

by musicman722


Cuddles and Corsets

“I must say, your room is really nice.” Adagio said as she sat upon the plush bed. It was her first time entering Fluttershy’s home and room. She was able to come over because of the school break and Fluttershy’s parents not being home for the day. Needless to say, it did spark a few naughty thoughts when the timid girl made her offer.

“I know it’s nothing like your room, but this is all I have.” Fluttershy said, jumping onto the pile of plush animals on her bed.

“Don’t sell yourself short, Sweetie. If anything, I thought you would have more live animals in here.” Adagio leaned back to lay next to Fluttershy.

Fluttershy blushed. “I did once, but I had to let them go when my mom started to complain about the smell. That, and the ferrets kept stealing her makeup.” She said with a giggle.

Adagio laughed. “Then I better hope they don’t find out you’re holding me here.” she said, staring into Fluttershy’s eyes with a sultry expression. “I’m told that I’m quite the animal in the bedroom.”

“EEP!”

“So what’s your ulterior motive for bringing me here?” Adagio asked. “I can’t believe you went through all that trouble to bring me to your room just for show, right?”

Fluttershy tried to hide behind her hair as she responded. “W-well, I thought that we could maybe cuddle and talk...or kiss.”

“Kisses, huh?” Adagio’s grin took on a predatory look as she started to crawl over to Fluttershy. By the time she was right on top of her, the timid girl’s face looked like it would burst into flames. “Not that I’m complaining, but I get the feeling that isn’t the only thing you want. Right, Sweetie?”

Fluttershy shook her head, but it was the second of hesitation that all but confirmed it for Adagio.

“Not talking, huh?” Adagio said. She let her body press into Fluttershy’s as her voice slipped into a Russian accent. “No matter. I have vays of making you talk.” She started her interrogation with a small kiss on the lips and then a line of them along her jaw and neck. The squeaks she earned grew as Adagio went down to the collarbone, but not a single word peeped out of those perfect lips.

“I see you’re stronger than I thought. Perhaps this will open those pretty little lips of yours.” Adagio returned back to kissing her mouth, but this time she used her tongue to penetrate the defenses, as it were. Surely a tongue could untwist this tongue-tied tart. It certainly had an effect as Fluttershy’s eyes went wide with surprise before she melted into the kiss.

The clash of tongues was cut short as both combatants needed to breathe.

“Still not talking?” Adagio asked, panting between words.

Fluttershy, who was in a similar state, responded by sticking out her tongue. “You have to try harder than that. I’m really good at being quiet.”

“I can tell. Perhaps I’ll need a change of tactics then.” Adagio said before her hands dived to Fluttershy’s ribs, intent with tickles.

The poor girl below realized what was happening, but it was too late. The terrible tickles wracked her body with laughter. “No! Hahaha! S-stop it! Hehehe! That’s-haha-cheating!”

“This stops when you talk!” Adagio said. It was foolproof. Not even her sisters could withstand her tickle interrogations.

“Alright, I’ll talk! I’ll talk! Just sthaaap it!” Fluttershy tried to say between laughs.Given her reprieve, she took a moment to compose herself. “Yes, I did have another reason for bringing you here.”

“Oh, and what would that be?” Adagio made a mental cheer to herself for figuring it out.

Fluttershy placed a finger on Adagio’s lips. “Nuh-uh. If you want to know that, I want another kiss.”

“Someone’s certainly become more assertive, not that it’s a bad thing.”

“More than you kn-Oh!” Fluttershy was cut off as Adagio renewed her assault on her mouth.

As Adagio made her deep kisses, she couldn’t help but wonder what Fluttershy would bring her here for. ‘There’s no rational explanation that doesn’t lead to naughtier things. Then again, she could just want to go watch TV or play with her animals after this. Although, I wouldn’t mind trying to keep teaching her that sexy walk.’ Her thoughts were cut short when a familiar ratcheting sound entered her ears.

Wait, is that…?’ A quick test of her wrists confirmed it. ‘Now why would she have handcuffs? Unless...’ Before she could ask, Adagio felt a pair of hands grasp her face.

“The other reason I brought you here is to show you how much more assertive I’ve become, thanks to you.” Fluttershy said with an almost too innocent look on her face. “I hope you don’t mind. I mean, feel free to use the safeword if you think I’m being ‘too much’.”

I don’t know if I should be proud or scared.’ Adagio thought as Fluttershy slipped out from under her and walked out of sight, leaving only the sound of rummaging to indicate she was still there.

“Ah, there you are!” Fluttershy said, her voice sounding like it came from under the bed. All that could be heard was the sound of a heavy box moving across the floor, and then several locks being undone.

That many locks on a surprise can’t mean anything good.’ Adagio felt Fluttershy’s presence straddle her back and lean towards her head.

“Sorry, but I don’t want to spoil the surprise for you.” Fluttershy said before placing a sleeping mask over Adagio’s eyes, and then what could only be earmuffs on her ears.

Cut off from her senses, Adagio became quite aware of Fluttershy’s movements on the bed. How her knees were pressed into the hips before moving down to the feet and off the bed. There was nothing for a second before hands grabbed her ankles and spread them, locking them into place with a bar. The next action caught Adagio off guard. One hand was pressed sideways on the middle of her butt while something was shoved into her crotch area.

“S-Sweetie? What are you do-ing!” Her question was answered by the loud buzzing she felt. She grit her teeth in vain, trying not to moan in pleasure. Every thought she attempted to form was scattered by the constant buzzing. Adagio tried lifting her hips to escape the vibrations, only to receive a sharp smack across her bottom, forcing her back down and harder onto it.

It felt like it would continue on forever, but when Adagio was nearing her peak, the vibrations ceased and were removed, leaving her a moaning mess. Before she could request its return, Adagio felt the earmuffs and mask be removed from her face. Blinking away the bright light, she turned her eyes upon the most magnificent thing she had ever seen.

“I think my new pet likes what she sees.” Fluttershy said. She was decked out in a faux-leather corset that just barely covered her nipples, thigh high stockings, and long gloves. Her panties were of the same material but had a metal ring in the middle of it. In her hands was a long, thin riding crop that she kept pressed against her breasts. To top it off, she stood on a pair of black high heels that screamed ‘I’m going to fuck you and you will like it’.

“Um, Fluttershy? What’s go-” she was silenced by a leather clad finger.

“Shhh. Right now, you’re to address me as ‘Mistress’. Failure to do so will result in punishment, pet.” Fluttershy said.

Her words sent a tingle up Adagio’s spine. She wasn't new to this, but seeing Fluttershy all dressed up in dominatrix gear with an attitude to match made her feel warm in certain places. She mustered her resolve and played along, “What are you going to do, Mistress?”

Leaning into her ear, Fluttershy whispered, “I’m afraid I’m going to have to punish you, you naughty pet.”

Adagio shivered at the implications and the possibilities. Having never seen this side of her before, Adagio couldn’t even begin to guess at what was to come, besides herself that is.

“Punish me for what, Mistress?” Given everything she had done, not to mention all the teasing, there was no telling what she had done to deserve this. Maybe she should do it more often if this was the result?

Fluttershy chuckled, “Oh my, now that would ruin all the fun and we can’t have that, now can we? Just do as I say, and maybe you’ll get a special reward at the end. I’d hate to have to punish my pet more than necessary.”

Another shiver creeped across Adagio’s skin as she nodded. “Y-yes, Mistress.”

“Good girl.” Fluttershy said, petting Adagio’s head. Swinging the crop around, she gave a few light taps to her rear. “Now get on your knees and lift this up for me, but keep your head down.”

It was easier said than done with one’s hands cuffed behind their back. However, Adagio’s routine exercise wasn’t for naught as she managed to use her hips to move her body into position. Her face was heating up as she was thinking of reasons Fluttershy would make such a request. Worse was that Adagio knew there was probably a stain in her crotch area and that it would be visible as day. She tried turning her face to look at Fluttershy and watch her next move.

“Oh dear. It looks like my pet made a mess of herself.” Fluttershy said, her voice sounding too innocent for her actions as she trailed a finger up between Adagio’s legs. “This won’t do. I’ll have to remove them.” Delicate, yet firm hands deftly undressed Adagio, letting the fabric rub across her skin as it was pulled down her derriere.

Adagio shivered as her ass felt traces of her mistress’ breathing across her skin. She had always imagined Fluttershy to want to see her without pants, just not like this. ‘What is she thinking now? Where are her eyes? What is she going to do next? Am I this much of an influence on her?’ she thought as she waited for Fluttershy’s next move.

“I’m sure you’ve heard it before, but you have a very beautiful bottom, Adagio.” Fluttershy said, tracing a finger across one cheek towards the crack. “So full and juicy, like a peach. I could almost sink my teeth into it. I bet your bottom was used a lot to tease others, isn’t that right?”

“Yes, mistress.” Adagio said, nodding. “It was part of the whole sex appeal I ha-AH!” She flinched from the new hand sized print on her skin. The area felt like it was on fire and sparking with electricity by the tingling sensation it left behind. Yet, like an incessant itch, Adagio needed more to quell it.

“That, my dear pet, is a taste of your punishment. You’ve been a naughty girl teasing everyone at school with these hips of yours. Teasing me with them. If you like to feel their eyes on your butt, you can feel my hand as well.” She delivered another slap, this time on the other cheek. “That one was for being rude and not thanking me for your lesson.”

“T-thank you, mistress.” Adagio said, trying to form words out of the haze of pleasure in her mind. Not that she would admit it to anyone, except maybe Fluttershy after this, but her butt was very sensitive. Part of the reason she wore tight pants was because of how they felt when they stretched around her rump. No matter how many times she pleasured herself, it always started and ended there.

“Ah, ah. You’re supposed to add ‘May I have another?’” Fluttershy said, pinching one cheek.

“Thank you, mistress. May I have another?” Adagio tried to keep her ass still. It wouldn’t do well to make Fluttershy think she was enjoying her punishment.

Fluttershy traced a finger over one cheek. “I’m going to give you ten. I want you to count them off and don’t forget to thank me and ask for more.” Then without warning, she struck firm on the flesh.

Adagio’s voice came out as a squeak. “One! Thank you, Mistress. May I have another?”

Smack!

Her flesh was now fire. “T-Two! Thank you, Mistress. May I have another?”

Smack!

The fire turned to an inferno. “Th-Three! Thank you, Mistress. May I have another?”

Smack!

The inferno became lightning. “FFFFour! Thank you, M-Mistress. May..May I have another?”

Smack!

The lightning struck to her core. “Ah! Five! Th-Thank you, Mistress. May I have a-another?”

Smack!

Her core made her twitch. “SSSSix! Thank you, Mistress. May I...have another?”

Smack!

Her twitches became desire. “Mmmf! S-Seven! Thank you, Mist-ah-Mistress. May I hah-have another?”

Smack!

Desire transformed into need. “EEEEight! Thank you, MMMistress. May-ah-May I have another?”

Smack!

The need must be satisfied. “Nine! Tha-hank you, My-Mu-Mistress. Please! May I please have another?”

Smack!


Adagio howled with pleasure as her mind was overcome. For the barest of seconds, she reached a state of nirvana that words couldn’t describe before she came crashing back down to reality. Her still buzzed mind only just registered that she had been moved to a new position sometime during her high. Her arms were no longer cuffed behind her back, but instead stretched out in front of her in a v-shape and secured to the headboard corners with a length of soft rope. She was still on her stomach, but now her hips and legs were spilling over the edge of the bed. Her ankles were bound by a longer spreader bar, displaying her privates for the world to see should anyone walk in at that moment. However, the most important thing her mind did recognize was the sight of the very displeased dominatrix smacking a crop in her hands.

“I gave you a punishment, pet.” Fluttershy said. Her voice held a cold fury only a kind person could wield. “Do you know what a punishment is?” She waited for Adagio to nod in response. “Really? Because I don’t seem to recall saying you could take pleasure in it!” She slapped the bed in front of Adagio’s face with a loud smack, forcing her to flinch.

“I’m sorry, mistress.” Adagio said. The harsh glare she was receiving sent chills down her spine. She knew she messed up now, and yet the anticipation for what was coming excited her.

“Not yet, you’re not.” Fluttershy said. She then twirled the crop in her hands. “But since I’m so kind, I’m going to let you choose what happens next. So what will it be? Seabiscuit or Old Yeller?”

Adagio tried not to let her worry show on her face. ‘Sea spray! What do those even mean? Can’t think for too long. She wants an answer soon.’ she thought. ‘Umm...Old Yeller may be what it sounds like. In that case, better go for the safer one. At least it relates to the ocean. Sort of.’ She bit her lip before giving her answer.

Fluttershy smirked. “I figured you might choose that one. Was it the name? I don’t suppose you know the significance of it do you? No? Well, you’ll find out soon enough.” As she left Adagio’s vision, she trailed the crop from the top of Adagio’s spine all the way down to the tailbone, causing her back to arch.

Adagio tried to follow her mistress’ movement, but she couldn’t turn her head far enough. Instead, all she could see was Fluttershy’s reflection in a nearby mirror. The girl was crouched and messing with something near the spreader bar. Adagio thought she saw a small bottle with a pointed cap. She had to face forward again as turning her head so far hurt her neck.

“Would my pet like to say hello to Seabiscuit before he goes to work on your naughty ass?” Fluttershy asked. “I know he’s happy to see you. Say ‘hello’, Seabiscuit.” She held in front of Adagio’s face a dildo. A long, hard, girthy, and veiny horse cock dildo. It even had a flare and medial ring.

“Oh, it would be rude of me not to introduce my pet to his friend, Old Yeller.” Fluttershy said. She then produced a shorter dildo, but this one was in the shape of a dog’s dick with a large knobby base, and it could expand further if the small attached pump was any indication.

Adagio’s heart rate skyrocketed and her face was red enough to live up to her Russian acting. She had a couple simple dildos at home, but none of them were close to as big as these two. The fanciest one had some bumps and ridges on it, but that was it. ‘I’m so screwed. No, I’m beyond screwed.

“Mistress, those will break me if you use them!” Adagio said. “I’m sorry! Please don’t use those things on me!” However, despite her pleading, she could already feel her fluids trailing down her legs and her holes flexing for the future intruders. Worse still, she couldn’t bring herself to say the safeword.

“Isn’t that the idea? Naughty pets must be punished, and you’ve been very naughty.” Fluttershy said before removing the dildos from view and returning to her spot behind the butt. “Now I know I let you choose which one for me to use, but I feel just awful if Old Yeller was left out of all the fun. I know just the place for him.”

Adagio had to bite her tongue to stop her squeal when she felt the cold liquid flow down between her ass cheeks. She couldn’t help the following moans when Fluttershy spread generous amounts of the lubricant around and in her asshole. Adagio felt her heart skip a beat when the equally lubed dog shaped dildo prodded her back door.

“Now be a good pet and don’t clench.” Fluttershy said.

The next few minutes were filled with Adagio’s screams, whether it be from the pain or pleasure, none could tell. Old Yeller lived up to it’s name as it pressed deeper and deeper into Adagio’s ass, stretching her to the limit. After what felt like forever, the dildo was set secure and snug in Adagio’s asshole.

Adagio herself was panting from the exertion. All she could feel right now was the large object lodged in her butt. She couldn’t help but moan when the knot started to expand, making it impossible to remove. Her mind was over the moon from the sensation, so she almost jumped when Fluttershy spoke into her ear.

“You like that, huh? Well from now on, if you’re going to act like a bitch, you get rutted like a bitch.” She said. “Are you a bitch, pet?”

“Yes, Mistress. I’m a bitch! A dirty, slutty, bitch! I’m your bitch!” Adagio said. Her words felt strangely cathartic as well as making her skin crawl with pleasure as she tried to take more of the dildo. “Punish your bitch!”

“Oh, I intend to.” Fluttershy said. She rubbed, spread and fingered Adagio’s pussy to make sure it was wet enough, but it didn’t need much coaxing to become a flood of fluids. She then pressed the head of the horsecock to the entrance and pushed.

Adagio could only gasp in silent screams as the thick dildo filled her all the way up to her womb. Just the feeling of being completely filled sent her mind for a few loops. ‘Sea spray, it’s like I’m a virgin again. I can’t let her break me like this. I don’t think I’ll be on top anymore if she does. But...would that be such a bad thing?’ Her thoughts were cut short when she felt the dildo in her vagina being dragged out and then shoved back in again.

Fluttershy kept thrusting the false member in and out, sometimes giving it a twist to mix things up. “You’re always teasing me. Your stupid, sexy ass is always in my mind during school. Those innuendos you make when we talk. Even the clothes you wear! Well, if you like teasing so much, then I’m going to tease you.” She increased her pace, making Adagio moan louder and louder and when it seemed that she was close, Fluttershy pulled the dildo out.

To say Adagio was frustrated was an understatement. She was almost to the edge when the pleasure stopped and she was brought back to earth. But before she touched ground, the dildo went back inside her and began to elevate her once more, only to repeat the process again and again. Adagio’s addled mind didn’t know how long she endured this roller coaster of ecstasy, but she knew she had enough.

She twisted her head around and with a pleading look, said, “Mistress, please let me cum! I’m sorry for teasing you. Just please let me cum.” Her muscles were starting to feel sore from the denial of release. She didn’t know how much more she could take.

Fluttershy hummed, then said, “Alright pet. I think you’ve learned your lesson.” She pushed the horsecock in again, as deep as it could and pistoned it in and out, letting Adagio reach her release this time. “Oh my, you really made a mess, pet.”

Adagio didn’t care at the moment. She finally climaxed and now her punishment was over. She just laid still as she felt her restraints being removed, not having the energy to get up right now. The beast cock in her ass was deflated and removed as well, making it feel like it left a gaping hole.

Her mind in a post-orgasm haze, Adagio watched as Fluttershy sat on the bed, leaning against the headboard. Fluttershy hooked her hands under Adagio’s arms and dragged the limp siren into her embrace with Adagio’s head on her bosom. Once they were in a comfortable position, Fluttershy ran her fingers through the massive orange hair.

“You did a very good job.” Fluttershy said, “My pet is such a big girl for taking her punishment so well. I think you deserve a treat.” She then pulled her breasts out of her corset and guided Adagio’s mouth to a nipple.

“Thank you, Mistress.” Adagio licked and suckled almost as if she was breast feeding. She tried to gauge what her Mistress liked by changing up what her tongue did. Her Mistress seemed to like it when she tried to squeeze and suck for her non-existent milk.

Fluttershy smiled down at her and then reached over to the nightstand to grab the large horsecock dildo, still wet from Adagio’s fluids. “Now that you’re happy, I think I might treat myself as well.” she said.

Adagio almost stopped what she was doing as she watched her Mistress deep throat the dildo down to the base and remove it like a professional sword swallower. She felt her face heat up when her Mistress licked her lips and sigh.

“Apparently, my pet tastes like peaches. I like that.”

“Anything for you, Mistress.” Adagio returned to her work with new fervor.

“Really, now?” Fluttershy cupped Adagio’s chin and locked eyes with her. “Then how about at the end of each week I train you to be a proper pet? Of course, I may have to punish you for any teasing you do in between sessions.”

Adagio paused as she mulled over this new information. She had almost free reign over the teasing she did to Fluttershy, but this would take the teasing to new levels, especially if it resulted in something like this. Not to mention, it would give Fluttershy a place to practice her assertiveness, or at least until she could do it in public. Besides, when was the last time she had gotten her rocks off like this? Adagio guessed it was true what they say about the quiet ones. If anything, it would be interesting to see where this new development in their relationship would go.

“I would love that, Mistress.”

Fluttershy smiled. “Alright, pet. But before we can do anything, I need you one thing for me.” She leaned into Adagio’s ear and said two words.

“Wake up.”

*****

Adagio’s eyes shot open and she took in a huge breath as though she nearly drowned. She sat up and swung her head around the room only to find darkness and her bedside clock indicating it was almost time to get up for school. She took a minute to calm down her racing heart.

“That was....just a dream? But it felt real. Way too real.” A peek under her sheets confirmed her suspicions. “Great. I just changed these yesterday.” She laid back on her pillow and cursed. “Thanks to that dream, I’m going to be horny all day. I hope Fluttershy won’t mind the extra teasing.”

A beat of silence.

“Note to self, be very careful entering Fluttershy’s room, and try to find out how much she knows about BDSM.”
