In the-*BONK!*

Rainbow Dash awoke to the sudden chill of something cold clasping around her member. She flinched and gritted her teeth as the cold object slowly started stroking it, unsure of just what was going on. Slowly, the pegasus eyelids fluttered open, revealing that she was in a place she didn't know, with lights too low to see anything, and something keeping her body restrained. Looking down, she found that all her limbs were under metal straps attached to a large rack, even her wings were bound to it (Take that, Cupcakes). What's more, she was also stark naked, her rod even at full mast.

"Oh, so you're finally awake now?" spoke a familiar voice, making a clapping motion as the lights suddenly came on.

Dash's eyes went wide at the sight of her captor. Of all the ponies in the world that it could've been, it was Rarity, the unicorn smiling as she gripped Dash's throbbing rod harder. Things simply weren't making sense here. Rarity was dressed provocatively, way more than she would usually wear; she wore a tight black corset that clung to her ample breasts and accentuated her hourglass figure. Looking down, she found her wearing a thin, black thong with matching stockings, even wearing leather gloves that went over her forearms. She also wore a kind of masquerade mask, having small wings around the sides as she donned a dominatrix cap, a small hole in the brim of it for her horn.

"I was feeling a tad guilty about hitting you too hard when you came in" Rarity suddenly said, smiling as she leaned in.

"Rarity, what the hell is going on here?" Dash demanded to know. The fashionista merely giggled a placed a finger to Dash's lips.

"Please, darling, do be sure to behave and address me as 'Mistress' while you're here" Rarity stated with a slightly threatening edge to her voice. Dash simply quivered as Rarity's grip tightened. "Such a lovely piece you have here, darling. Though I must say, Pinkie's description of it doesn't do you justice" she stated with an unnerving giggle.

"Pinkie?" Dash questioned, feeling hurt that Pinkie broke her pro-"Wait...Pinkie would never break a Pinkie promise!" Dash argued back, glowering towards the leather-bound mare.

"You're half-right about that, darling" Rarity started, "She wouldn't even break such a promise, unless of course, she were talking to me" she stated, clicking her fingers as another set of lights came on. All the blood drained at the mere sight of what it is she saw; Pinkie, only strapped in some kind of...sexual torture machine. Two pistons were hastily pumping dildos and out of Pinkie's pussy and ass, electrodes were attached to her nipples, and she was even blindfolded with a ball gag in her mouth, the BDSM tool downright shimmering with pink mare's saliva.

Before Dash could inquire why it was Rarity was doing any of this, she felt something blindfold her from the behind. Judging from the hum of magic and the momentary flash of baby-blue magic, it was clear that Rarity was to blame. As Rarity tightened the blindfold, she started fondling Dash's testicles, practically pinching them in-between her finger and thumb. The only thing Dash could think about-aside from how incredibly hot this whole situation was-was where everything started going so wrong. This thought was quickly interrupted by her jaw being forced open as a plastic ball was soon shoved into it.

"You should've seen the look on my face as soon as Pinkie told me about this meaty rod of yours, I just couldn't believe such a statement. But of course, Pinkie insisted she was telling the truth, so I decided to find out for myself. Luckily, you came into the boutique today, giving me the perfect opportunity to find out" Rarity stated, Dash's mind instantly snapping back.

(Flashback)

Dash flew towards Carousel Boutique cautiously. She had done it with three of her friends now, meaning she'd have to do everything that she could from being found again. Then again, a small part of her wondered why it was that she even bothered. The others had found out so easily, and she even tried her hardest at that time, yet she was till found out anyway. Dash gave a small sigh and opened the door. She had promised to help Rarity and she was bound by it. Among everything else, she had to wonder if she had a problem with saying 'yes' to everything, but that could wait for another time.

"Hello?" Dash called out, trying to find the fashionista. No answer came. She walked around a little, trying to find any evidence to prove whether or not Rarity was home. It was likely that she was busy working on a new dress design, which if she remembered properly, was located upstairs. Once she had reached the doorway, Dash's mind automatically started wondering how Rarity would react would her secret be found out. The only upside that she could think of was that despite being a gossip, Rarity always kept her closest friend's secrets the way they were; a secret.

Hesitating only slightly, the bearer of loyalty opened up the door, only to be met with a heavy *whack!* against the back of her head.

(End Flashback)

"After knocking you out, I took a good look at your hidden package. It didn't seem like much at first, but it definitely became something great overtime" Rarity giggled, patting the flaring head of Dash' member. Dash merely let out a shudder. To think, the one friend of hers that she didn't spend much time with was some kind of dominatrix, and a pretty extreme one from how she treated Pinkie. She was terrified to think what she might do with her. She wasn't able to see, but she could hear Rarity walking around, something whipping about. Wait...whipping?

*Thwack*

Dash didn't have more than a split-second to prepare herself as the lash of what felt like a crop went across her stomach. The sting burned against her flesh, the normal cyan on her fur being coated red with the blood that started trickling. Another lash went across her left breast, then her right one. If not for the ball gagging her, she'd certainly be screaming. Then again, she was still screaming, drool building up around the plastic sphere. Rarity seemed to lean in, chuckling in her own sadistic way as she licked Dash's whip wounds. That at least helped out, though she still felt searing pain covering her entire body.

"I understand this may seem a little...painful, to put it lightly, but you simply have to be punished for playing with my pet without my consent" Rarity said as she stroked Dash's member, the latter only whimpering as she felt more of her blood trickle into her fur. Rarity leaned lower, licking around Dash's urethra while she pinched around her medial ring. The way that she toyed with her body...it just wasn't natural. Dash's body was left confused about whether or not she should be in pain or if she should be enjoying it. Her rod seemed to have a mind of its own on that deal.

Rarity snickered, kneading the perky blue breasts dangling in front of her, tweaking the erect nipples between her fingers. The alabaster dominatrix slid a finger in between Dash's legs, right across the moist lips of her vulva. After an audible schlick sound, Dash knew that her body was betraying what her mind thought. Suddenly, the ballgag was adjusted slightly so it slacked out of Dash's jaw, just long enough for Rarity to push her fingers into the pegasus' mouth. her tongue draped around the leather-tipped gloves, tasting as much of her sex as she could.

Rarity licked around the base of Dash's girth, the pegasus squirming about from the contact. "From what Pinkie's told me, you have an incredibly sensitive little cunny, but I don't think anyone's actually given any proper treatment" Rarity mused ominously. Dash could hear her walking away, paranoia building as she thought what Rarity would be doing. A few clicking sounds went off and something hard suddenly began poking and prodding between her legs. "This should help relieve you of that" Rarity added soon after. A few more clicks and then a magical force exuded itself upon her balls, lifting them away while the hard object suddenly started started pressing into her opening.

Something you could've probably gathered by now was that Dash's cherry was still technically kept, or at least it was until the piston busted it right away. Dash screamed out into her gag, the pain in her loins being far worse than anything else she had experienced as of lately, not even the one time she was whacked below the belt by a loose floorboard. Blood started dripping down her legs and onto the machine, Dash's whimpering being the only audible thing.

As if being blindfolded weren't enough, there was the paranoia that came with it, never knowing exactly who was doing what, particularly the sudden tongue around her shaft. At first, she thought that it was Rarity, somehow aroused enough to the point that she'd want to be rutted, but of course, that wasn't the case. Some faint whipping sounds and soft yelps could be heard as the ministrations continued, meaning the unthinkable must've been happening.

"Yes, that's right. You love the taste of that dick, don't you?" Dash heard Rarity ask, a small confirmational grunt happening soon after. Another whipping sound, followed by another yelp. "It couldn't possibly taste better than my precious jewel, you damned slut, filthy swine!" Rarity yelled as she began furiously whipping the poor baker. Dash was actually crying over her poor friend, desperately wishing she could've been there to prevent something like that from happening. She struggled against her bindings, trying to find some way to come to Pinkie's rescue. It just wasn't right for her to stand there being pleasured while poor Pinkie to be whipped and slapped and who knows what else. Unfortunately, without any leverage, and all her limbs bound the way they were, not to mention the piston continually pumping her pussy ragged, there wasn't anything she could do but take it.

The licking and suckling stopped suddenly, the machine slowing down to a snail's pace. All that could be heard was Pinkie's pain-filled whimpering and Rarity's giggling. Dash's tender pussy was incredibly grateful for the sudden gentleness, though her rod kept on throbbing painfully, burning up so much, she could feel it. There was a sudden wetness that suddenly dragged itself across her shaft, a small moan escaping the lips of the one doing it. Dash suddenly felt a leg coming up and a moist cunt coming down on her member. Her head started flaring out at the sudden tightness, waves of pleasure enveloping her as both of her sexual organs were being stimulated.

Dash could feel breasts poking against her chest, a panting mare bouncing her hips off her. She could feel her gag being magically moved off, followed by a pair of velvety lips pressing themselves against her. She couldn't tell anything from the pleasure building up, all she could do wrestle her tongue against the invader and thrust to the best of her abilities. There was a licking sensation going on around her fleshy orbs, someone's fingers pinching her clit while the other started grinding her hips around Dash's medial ring. Eventually, the mare fucking herself had really started leaning in, bottoming out Dash's throbbing rod while her vaginal muscles converged even tighter. All of her senses were being overstimulated, bringing her to climax far harder than she ever had. She let out a throaty moan within the mouth of the mare kissing her while the rest of her body twitched, pulsated, and generally spazzed out. Both her pussy and her member let out a huge torrent of her sexual fluids, the juices mixing about on the floor as Dash rode it out.

The piston stopped altogether alongside the fucking, the mare responsible sliding off of Dash with a loud pop soon after. Her blindfold was raised, revealing a smiling Rarity with a red face, the mask from earlier off, revealing her profile in full sight, or at least what Dash could manage with her practically blank mind. The restraints were released and Dash was lifted off the piston, unceremoniously falling on the floor with a loud thud.

Rarity giggled and wrapped an arm around Pinkie's shoulders. "Isn't she just lovely?" she asked, the latter nodding. Pinkie merely nodded and nuzzled Rarity's neck.

"She's nowhere near as lovely as you are, Mistriss" Pinkie whimpered, Rarity simply silencing the mare with a kiss.

"Hush now, you've got a mess to clean up" the fashionista stated as Pinkie sighed.

Author's Note

For those who don't know what I meant, I was talking about how Dash's wings weren't restrained in the actual fic Cupcakes. We've all seen how strong Dash's wings are in the show, so she should've been able to break free using just them. She even had all the time in the world while Pinkamena went on a generic evil monologue.

Because of that, I decided to have Rarity bind Dash's wings first, effectively cutting off her only real means of escape.

(And yes, obviously Rarity was the one bouncing around on Dash's dick)
