The Mare of Her Dreams

The mysterious pegasus approached Twilight, who was laying on her back, legs tied to the bedposts. Bits of rainbow hair peeked out from underneath a uniform of black leather that otherwise concealed her identity. The pegasus smiled mischieviously, her eyes scanning across her victim slowly, as she planned out all the disgusting and unspeakable acts of torture that she was about to perform. "You've been naughty, haven't you, slave?"

"Y-yes ma'am..."

"So you deserve punishment, don't you?"

"No ma'am, please don't!"

"Choo late" Rainbow Dash mumbled through the thick leather handle of a riding crop, before lightly slapping it against Twilight's flank.

"Oh, ouch! I've been so naughty, mistress!"

Rainbow slapped Twilight a little bit harder.

"Teach me a lesson!"

Rainbow brought the force right up to the limit— She knew exactly how much Twilight wanted and exactly how much was too much. Another swift smack to the bottom sent shivers down Twilight's spine.

"Oooh! Oh, Mistress, I'm so sorry, I'll never do it again!"

Rainbow spit the riding crop out of her mouth. "Oh, don't worry, I'll make sure of that..."

"What're you gonna do to me?"

"When I'm done with you, you won't walk right for a week." Rainbow threatened, before diving muzzle-first into Twilight's muffin. She pressed her face into Twilight, greedily lapping up the fluids that the excited alicorn was producing. To taste a goddess is to taste pure happiness and joy in liquid form, but Rainbow would have acted the same way if Twilight's snatch had tasted of rotten fish. Making Twilight feel good was the most important thing in the world to her at that moment, even if the character she was playing was contented in making her life miserable.

"Mistress! Oh, Mistress!" Twilight let out a series of small gasps as Rainbow Dash skillfully applied her tongue, licking all over, swirling it around under her clitoral hood... She blew a raspberry just above Twilight's vulva, simultaneously tickling and pleasuring the violet mare. As she continued to play around in the area with her mouth, a hoof wandered up and teased Twilight's vagina, pulling and stretching at it. She pushed against Twilight's marehood with some force, though not nearly enough for the relatively large limb to penetrate her.

With a toothy grin, Rainbow asked, "are you gonna beg me for mercy?"

"Oh please, mistress, let me go!"

"Not till you've learned your lesson!" Rainbow insisted as she pushed a little harder with her hoof, eliciting a pleasured grunt from her captive.

"I'm so sorry!" Twilight apologized, putting on her best 'scared face'.

"Oh, you will be!"

Rainbow's hoof was poised on the edge of penetration, but it was too large for Twilight to handle, and they both knew that. After another fruitless shove that made Twilight squeal, Rainbow moved her hoof down a little lower and pressed against Twilight's anus.

"Mistress, no!"

"Oh, I wouldn't actually do that..." Rainbow replied, pulling her hoof back to inspect it daintily, as Rarity might do. "Wouldn't want to get my hoof dirty. But that wouldn't stop you from enjoying it, you... you... uh... slut."

She made it apparent at that point that her other hoof was holding a butt-plug that was drizzled with lubricant. She pressed it against twilight's tight little asshole, gradually increasing the force behind it to overcome the initial resistance.

"Guh... Ah! Unfff... M-m-m-mistress..."

The tip of the plug was only just barely penetrating Twilight, stretching her sphincter around itself.

"I think you might be enjoying this too much." Rainbow remarked with a sharp thrust of the plug. Twilight moaned as it went in a half a hoof deep, but her taut rectum squeezed it back out to the same position it was in originally. Although Twilight was comfortable with anal play, the toy was bigger than anything she'd normally put in her ass. That said, the increase in size was her idea— something to fit with the bondage theme. Well, technically, since this was a dream, everything was her idea, but she wouldn't be able to appreciate that fact until morning came.

"I wouldn't want you getting the wrong message..." Rainbow continued as she pushed it a little harder.

"Oooh..." Twilight gasped, "No, mistress, it's too big!"

"No such thing as too big..." Rainbow insisted, giving the plug another push and a twist. Twilight's eyes squeezed shut from the intense pleasure, spiked with a twinge of pain. "...Just under-prepared!"

The plug was now a whole hoof deep inside Twilight, but still not lodged in place. Rainbow bent down and licked Twilight's pussy again, just slightly oscillating the buttplug inside her as she did so, and Twilight's back arched and she pulled at her restraints. With each stroke of Rainbow's tongue, the alicorn moaned softly, and with each inward thrust of the buttplug, her hips rocked and her body shivered.

"Please mistress! I can't take anymore!"

"You'll take every—" Rainbow pulled it back a bit before jamming it in a little further.

"Eep!"

"Last—" Rainbow repeated the same motion.

"Augh!"

The pegasus pulled the plug almost all the way out.

"Inch!" she shouted as she pushed it all the way in. Immediately afterwards, Twilight's anus reflexively squeezed down around the narrow part of the plug just before the wide base, locking it into position.

Twilight shuddered in delight, squeezing her rectum down around the toy, enjoying the feeling of being stuffed fuller than she ever had been. Rainbow came around to her side and kissed her deeply while reaching out a hoof to stroke Twilight's clitoris. The taste of her own godly secretions carried in Rainbow's saliva, but because of all the stimulation she was receiving, it was all Twilight could do not to bite down on the tongue that was exploring her mouth.

"You like that, slut?"

"Mmhmm..." Twilight mumbled.

"Then I guess I'm not doing my job well enough, am I?" Rainbow asked as she moved back around to Twilight's posterior. She wrapped her mouth around the base of the plug and gave it a sharp pull, almost dislodging it.

"Oof..." Twilight uttered as her eyes clenched again.

Rainbow nibbled on one of Twilight's labia gently, pulling at it with her teeth.

"Ow, ow, ow..."

Satisfied that she had induced enough pain to meet Twilight's slightly masochistic needs, Rainbow reached her hooves across Twilight's upside-down, restrained, form. As Rainbow stared fervently into Twilight's eyes, breathing hard, Twilight could feel the end of a strap-on rhythmically touching against her marehood, threatening to breach at any moment.

"Please, mistress, no!"

"I have no choice, you drove me to this!" Rainbow replied as she penetrated Twilight quickly and forcefully. She made sure to lean in such a way that she was pressing the back wall of Twilight's vagina back towards her rectum, squeezing the wall of flesh between them and effectively stimulating a number of sensitive nerve endings.

Twilight threw her head back in ecstasy, her body failing to put on the show that she tried to continue with her mouth. "No —MMMPH— mistress, stop, it hurts!"

"You should have thought of that before— before uh... uh..." Rainbow Dash broke out laughing, while continuing to thrust her artificial member in and out of Twilight. "Sorry, Twi, I can't think of anything."

"Ah-ah-ah-ah... I... Don't... Care... Keep.... Going... AHHH..."

"Before you uh... stole my... cloud?"

Twilight started laughing too. "Why... Ahhhhhhhhh... fffffffpt.... would I want a— Gah! ... A cloud?"

"I don't know, I told you I couldn't think of anything! This is complicated!" She insisted, glancing down at the gear strapped to her thighs.

"Any stallion can— MMmph— Any stallion can do it."

"Yeah, well a stallion can feel it. I just gotta guess!"

"No need to say any more," Twilight noted as a glowing violet aura appeared around her horn, "Just slow down a little so I can— erk... Concentrate."

Rainbow Dash slowed down, not to do as Twilight was telling her, but because she was concerned about what the alicorn was getting at. "Twi, what're you—"

Rainbow stopped suddenly, and her eyes shot open. She could suddenly feel something that wasn't there before, and two nearly comical popping noises coincided with two more unfamiliar body parts dropping into place. "Twiiiiiii..."

"That lasts for a good thirty minutes. Make it count, master."

With a newfound confidence and lust burning in her eyes, Rainbow Dash started thrusting again, and her— or, his, eyes, bugged out of his head. Suffice it to say that the new sensations were not making it any easier to concentrate on what she was doing. "Twilight... I think I'm gonna..."

"Already? You haven't even— WAHH-" Twilight took two sharp breaths and fought to keep her eyes open through the pleasurable stimulation. "You haven't started the roleplay back up again!"

"Right— ERK... You've been— ergh— stealing my clouds..."

"Rainbow..."

"I'm sorry... I ca— I just can't— Ah.. AHHH.... OH... Gosh... Oh my gosh..." She stopped thrusting and began panting heavily. Her tongue lolled out of her head, and her eyes betrayed a completely empty mind.

"You just came, didn't you?"

"I... I think I did..."

Twilight sighed. "Disappointing, wasn't it?"

"Well, that was just the first one. I can do it again."

Twilight shot her a look of incredulity.

"Wait, stallions can seriously only do it one time? I thought that was like... an urban legend."

With a flash of her horn that lasted only milliseconds, Twilight was free of her restraints and had pounced on the thoroughly endowed Rainbow Dash. Even in Twilight's dreams, Dash was a domineering creature who would never surrender the top position willingly— it had to be taken through force and cunning. But if Twi could manage to catch her off-guard, and she could win being on top, it was hers for the taking.

"Stallions can only really enjoy it once... But they can do it a bunch of times in a row, really." Twilight commented with a mildly sadistic smile, as she began riding Rainbow Dash like a bull. The plug in her ass was causing her a little discomfort, now that she was actively moving around, but it wasn't more than she could handle... Or more than she wanted, for that matter. She could've removed it with magic fairly effortlessly and painlessly if she so desired, but that wouldn't have been nearly as much fun. After all, the whole point of this game was to get a little roughed up...

"TWI?! AHHhhHhHhHHhhHHH! Fuck! Fuck! Fuck!"

Twilight used her magic to slip the first bead of a set into Rainbow's anus as she continued bobbing up and down on Rainbow's conjured member.

"Who's the mistress now?"

"Twilight!" Rainbow screamed.

"Damn straight, it's Twilight!" She replied, cramming another bead inside the mare-turned-stallion.

"Twilight?"

"Say my name... Bitch..."

"Twilight!" Spike shouted, trying to wake the unicorn. "Twilight, get up!"

"Unnh... Spike?"

"Yeah. Spike. Not 'Bitch'. It's 11 o'Clock!"

Twilight sighed. "And?"

"So, you were planning on seeing Rainbow Dash this morning! Even she doesn't sleep in this late. She's probably on her second nap of the day by now!"

"Huh... Right."

"Also, you need to open the libr—"

With a pop and a bang, Twilight was gone. Teleportation.

Spike shook his head in disapproval. "That pony, I swear..."
