Rainbow Dash tossed and turned about in her bed. Much as she wanted to, she simply couldn't fall asleep. There was something about this particular evening that had made her restless. The heat season had been over for some time, many mares had returned to normal, and she hadn't had sex in at least three days. So what was it that made her so insomniac?

"There's no way..." Dash sat up in her bed, pondering the idea of it. Was her libido keeping her up at night? Preposterous. Such an idea would sooner make her laugh than anything else. But if it wasn't that, then what could be keeping her up? Dash sighed. She had all kinds of things on her mind now, getting so concerned about them would only make it even harder to sleep.

Dash got up and headed over to the bathroom. If getting to sleep normally wasn't an option, than she'd have to go with drugs. She pulled an old bottle of pills out and looked at it. It was some really old medication made specifically for young pegasus ponies; it was supposed to make the wings go flaccid while simultaneously making it easier to sleep. She held onto it in case something like sudden wing-boners started making a case, but a sleeping agent helped just as much. She got a small glassful of water from her bedside pitcher and swallowed the pills along side it. Soon after, the effect of the pills took its course and Dash fell right asleep.

Deep within the confines of her psyche, Dash was found at the Wonderbolts arena, performing her best of abilities to Captain Spitfire herself. She tucked, turned, and soared through every obstacle, fought passed any wall that dared to obstruct her victory and broke through it, pushing her body far beyond its limits. By the time it was over, the captain had flown over to give her a medal of honor, even giving her the reigns of all the Wonderbolts. Dash was so happy, she squealed and grabbed hold of Spitefire, thanking her with multiple kisses running along her neck.

"Is this really how you greet a princess?" a voice suddenly said, making Dash go wide-eyed. She looked up, only to see that she wasn't embracing Spitfire anymore, but instead it was Princess Luna. Immediately, she let go of the lunar princess, backing away as the dreamy landscape faded into a series of stars along a midnight-blue sky. She could feel some kind of solid ground forming beneath her, giving her a chance to bow down before the princess of the night.

The princess wore her usual attire, consisting of a shimmering dress designed to resemble her mane, the fabric hugging her modest body gently. Upon her feet were small boots befitting of royalty, a crystal crown adorning the features on her head. Her wings were folded, but her mane and tail both undulated of their own free will, giving off a distinctly divine air to her.

"P-Princess Luna, I swear, I-I didn't know it was-" Dash tried to explain before the princess raised a hand. Luna simply gave the mare a smile as walked over to a silver throne that had materialized. She took a seat and crossed one leg over the other, keeping her smile pinned on the pegasus. Dash wasn't certain what the princess was doing in her dreams, but she was sure it couldn't have been anything good. Other ponies-IE Scootaloo-told her that Luna usually comes to ponies in their dreams when they're troubled by something. Then again, considering her sudden appearance, it seemed more likely that Dash was in trouble with the alicorn. Suddenly, Twilight's fear of disappointing the princesses didn't seem so ridiculous.

"I'm only here to ease you of your restless libido, Rainbow Dash" Luna suddenly said, surprising Dash immediately. Never in all her life would she ever expect to hear something like that come out of a princess' mouth.

"Seriously?" Dash questioned, completely skeptical of the idea. The entire thing just reeked of randomness.

"Even alicorns experience the need for intimacy during estrus, Rainbow Dash" Luna retorted, a slight blush forming on her muzzle. Dash's jaw went limp and merely hung down, practically smacking against the floor. Even for a dream, this was stretching the truth a little. Besides that, it wouldn't make sense for Luna to appear to her in her dreams if she wanted sex, she could simply go to her house instead. As far as Dash was concerned, nobody would find out about it.

"It's simply easier to come to your dreams. You've no idea of how determined the local tabloids are to ruin my good image" Luna stated, surprising Dash even more. "This entire world is your mind, and I can read it like a book" Luna continued before Dash could say anything. With a wave in her hand and a glow in her horn, the princess discarded her regal dress and royal adornments, now wearing a jet-black, lace negligee. "As much as I would love to 'talk dirty to you', I'm afraid we haven't much time before the sun rises and you awaken" the princess stood up and started sauntering closer, the amount of sultriness in her hips and tail swaying surprising Dash, whom of which simply stood still, staring at her.

Luna placed a hand under Dash's chin and lowered her eyelids, initiating a kiss between the two mares. If her lips were velvet, then her tongue was silk. Dash let a soft coo escape as she delicately wrapped her hands around Luna's slim waistline. Somehow, it felt real to her, as if all of this really was more than just a dream. Their tongues danced about both inside and even in-between each other's mouths, soft moans escaping them as they embraced tightly. Dash could feel Luna's heartbeat, and Luna in turn could feel Dash's.

The two broke away and looked at each other's hearts through their eyes. The flames of passion burned throughout Luna's as the smell of her arousal began making its way through the thin fabric she was wearing. Dash turned behind the princess and embraced her with one arm, the other one softly caressing her perky little breasts. Luna let out a small yelp as Dash's fingers traced small circles around her nipple. Dash herself merely continued to tease the princess' breast as she slowly planted small kisses along her neck, the soft bristles of her coat tickling her tongue.

Luna let out a throaty moan as she leaned back into Dash, her body heating up slightly more. Dash started playing with the princesses nipples a little harder, getting a twitch in the alicorn's glorious wings. Dash moved her tongue-based assault lower, tracing it along the edges of her dark blue feathers, then around the soft down gather along the slender bones. Dash had never gotten to do this to another pony's wings before, so she gladly jumped at the opportunity Luna had presented her with. Perhaps this was the way she had intended; to gift Dash with the moment to try something. Judging by the carnal moans the princess continued giving, Dash could tell she was enjoying it.

Once Dash had established her role as the source of Luna's pleasure, she snaked down the hand that previously embraced the princess and started to delicately stroke the moistening folds of her marehood. Her thin panties were already soaked through to the point where it actually started seeping onto Dash's fingers. The pegasus gave a smirk as she retracted her hand, Luna turning her head back to question her actions with a pleading look, only to blush as Dash traced her finger back up and into Luna's mouth. The princess suckled upon the digit, her tongue dancing around each individual patch of blue that it had.

By this point, Dash's member was already half its full size, poking out from the front of her pants and against Luna's back. The princess in question merely let out another throaty moan as she turned to kiss Dash once more, her free arm snaking around the pegasus' back and putting pressure on the base of her wings. Dash liked that. She liked it a lot. The pegasus moaned into Luna's mouth, even more-so when the latter had grabbed hold of her third leg. She stroked the shaft of it softly, the mast beginning to harden even further. After only a few more strokes, it reached it's full length, Luna breaking away from the kiss to lick her lips.

Once Dash had discarded her now-useless clothing, she presented herself to Luna, whom of which liked what she was seeing immensely. Dash knelt down before her princess once more, the latter now taking the cyan rod in her hand and stroking it. Dash let out a small, pleasured moan, practically a whisper to the busy alicorn. Once Luna had stroked the pulsating member enough, she started licking it. Her tongue traced around the base of the sheathe and slowly dragged itself up to the medial ring, to which Luna then planted a small kiss on, then continued doing so until she reached the crown of the head, where she proceeded to pop the pants snake into her mouth.

Luna's fellatio started out slowly, suckling upon the head as it flared out on the inside of her mouth. Dash let out a moan and started caressing her breasts, her wings twitching every which way but up. Luna started taking in a few inches of the meaty rod, her tongue wrapping around the sides and coating it in her saliva. Soon enough, she started bobbing her head on it, each time going down further than when she first started. Before Dash could even believe it, Luna had Dash's entire length hilted down her throat. The warm feeling she got from the lunar princesses throat muscles was incredible. She could almost swear that she was approaching her big 'O' as the muscles massaged every bit of her twitchy stick.

After just five minutes, Dash blew her warm seed all throughout Luna's throat, each shot eliciting a small thrust in her hips, her wings standing erect. Luna magically levitated Dash onto her back, stood up, and disrobed herself. Her gorgeous indigo coat shimmering alongside the starry backdrop. She straddled Dash as tightly as she could, taking the slightly flaccid rod in her hands. With a small pinch, Dash was standing tall once more, much to the princess' delight. She got upright and began leading the rod towards her dripping snatch, pushing the flaring head through her opening with a loud squelch.

Dash let out a carnal moan as she entered Luna's steaming love tunnel, the tight muscles squeezing her member like a vice. Luna started going down, her throbbing pussy taking in at least seven inches before she stopped herself, her face red and sweat beginning to form on her body. She slide down further, Dash's medial ring obstructing her advances just a moment before accidentally pushing too far, and taking in the next five inches before she could prepare herself. The princess of the night nearly screamed at the sudden prodding near her womb, her vaginal muscles clamping around the shaft even tighter, much to Dash's delight.

The pegasus grabbed hold of the crescent cutie marks and started withdrawing herself Luna, before thrusting it back in at a modest pace. While Luna was disappointed to have such a pleasant feeling withdraw before she had climaxed, she was more than delighted to have it suddenly shot right back up her hot cunt almost immediately after. Her breathing started getting heavier, her vision started getting blurry, she leaned down and embraced Dash as the latter continued thrusting as delicately as she could.

"Ha...ha...Harder" Luna begged cutely. Dash nearly came right then and there at the face Luna was giving her. It was just full of lust, full of need, so wonderful that Dash had taken her orders and started pounding the alicorn's pussy harder, thrusting until all sixteen inches of her was being rammed into the tight tunnel. For what felt like hours, the two continued like this; Dash pounding Luna's tight cunt while the princess let out one throaty moan after another. Wave after wave of pleasure shot through the both of them, each of their individual climaxes coming forth at an alarming rate.

Dash wanted to make sure that she and Luna climaxed together, so she started humping as hard as she could, her rod sliding in at a piston's speed to the sound of all manner of lewd noises from Luna's pussy. With one last thrust, the two mares both started gushing sexual fluids from their genitals, letting out loud moans of accepted pleasure as everything around them started going white.

For a short moment, the two merely rested upon each other, both of them having been satisfied to the point where movement in itself was not considered an option. "Was that...as awesome for you...as it was for me?" Dash questioned, one eye winking as the princess tried to steady her breath.

"It was indeed...as you say, awesome, Rainbow Dash" Luna answered, a small amount of magic buzzing around her horn. "However," Luna suddenly said, her voice having long since returned, "Isn't returning the favor something that friends do when one is gifted with something?" she rhetorically inquired, confusing Dash for a moment as a flash of magic enveloped them both.

When the light died down, Dash found herself standing, naked and alone in a much more purple area, a shooting star passing at a downward angle, which led to a bizarre discovery. Dash looked down at herself, and found that her entire member, even her testicles, had completely disappeared. Having such a thing happen all of a sudden had mixed results within the pegasus' mind. She wasn't certain if she should be happy for finally having normal genitalia, or saddened by the loss of something she had since birth.

"Is this what you're looking for?" asked Luna from behind her. Dash turned to face the source, but went wide-eyed at the sight of the princess. Luna now had what could be described as Dash's missing member, though it was much different from the way it looked when she had it. It was now an indigo color, and much, much longer. The monster now stood up, poking through Luna's perky breasts at an intimidating twenty-one inches at least. It even managed to gain some girth to it, the dark indigo testes between Luna's legs being the size of cantaloupes.

Luna giggled with a red face, amused by Dash's reaction. "The ability to control ones dreams is a wonderful thing, is it not, Rainbow Dash?" she stated as she walked forward, her breasts, hips and rod all bouncing with each step that she took. Dash was so surprised by the walking third leg that she had actually took a few steps backward, only to be magically grabbed by Luna and levitated over to her, held upside-down as the princess of the night giggled airily. She spread Dash's legs apart, smiling at the glimmering jewel presented to her. The alicorn grabbed hold of Dash's individual flank cheeks and held her close, breathing in the musk of Dash's arousal. Dash, on the other hand, was uncomfortably pressed against the medial ring of a huge mess of throbbing, alicorn meat.

Dash's body was re-positioned at an angle, the pulsating indigo rod being pointed right at her mouth as Luna gave her moistening folds a long, slow lick in a clockwise manner. As Dash's mouth opened to let out a throaty moan, Luna pushed her meat club into it with a particularly hard thrust, Dash's teeth digging into the pulsating flesh. Luna's grip on Dash's cheeks got harder for a moment, a little displeased with the sudden pain overwhelming her pleasure. Still, she didn't stop her ministrations on Dash's glistening folds. She gave small licks around the edge of the slick slit, suckling on her clit before pushing her tongue straight in as deep as she could get it.

Dash's jaw felt as though it was splitting apart, Luna's girth was simply too wide for her. That didn't stop the princess from her ravishing her throat though, forcing herself further down Dash as she could before she could sense the mare gagging. It seemed as though pleasuring her sopping cunt wasn't going to cut it for her, so she quickly re-positioned the pegasus' body once more, this time going doggy-style as the latter's tail instinctively moving out of the way as Luna mounted her, rubbing the flesh of her member between Dash's flank cheeks before aiming it at her target; Dash's pussy.

Dash let out a silent scream as Luna plunged the head of her rod inside her. She could practically feel her pussy changing shape to better accommodate the colossal meat missile. Luna moved slowly, trying to pleasure Dash as much as she could. The alicorn leaned down and started caressing Dash's breasts, squeezing and rubbing them as she started to push a few more inches into her. Dash just let out moan after moan as inch after inch was forced into her, her muscular walls tightening around the indigo member tight enough to practically squeeze it off. Her walls only tightened more as Luna's rod began twitching about inside her, her medial ring finally having met with her cervix, the meaty monster moving further inside the pegasus' tight tunnel.

Once they had gotten through the pain, Luna started moving a little faster, Dash's walls having been loosened up moderately enough so that her medial ring started poking her. Dash's mind was nothing but white, unable to see anything, unable to feel any part of her body as her crotch was continuously assaulted. She felt as though she were nothing more than a rag doll, a mere plaything to the all-powerful princess. Luna continued her fucking rampage through the valley of Dash's pussy, the head of it causing a sizable bulge to appear in the pegasus' stomach.

Dash wasn't certain when it ended, but she could feel her own juices opening up like the floodgate that it was, the result of her climax forcing the same from Luna. The princess shot enormous of spooge into Dash, the seed splashing back out in less than two seconds, yet she still kept cumming. Dash's entire body went limp at the feeling, her entire stomach expanding bulging out, touching the floor as Luna retracted herself. Her walls had been so tight that she actually caused Luna some great level of discomfort as she tried to withdraw, eventually popping out and landing flat on her royal ass. Dash's eyes had long since glazed over, all feeling leaving her body alongside all the seed spilling out of her white-coated snatch.

Rainbow Dash had awoken in a daze, her pussy quivering painfully and her chest and waist covered in warm seed. Looking under the covers, she found the head of her rod poking out of her pajama bottoms, mildly hard and spooge coating her upper body. As expected, she was given a very wet morning, courtesy of Princess Luna. She smiled at herself and sat up, suddenly overcome with pain all inside her mid-section and groin. She wouldn't be walking straight-or even at all-for weeks because of that dream, or so it felt. Still, she'd have to remember to try meeting Luna in real life, just so she could compare the feeling of the princess' pussy to how heavenly she felt in the dream world.
