Sharing with Auntie

Cadance lingered on her way back from the banquet hall, purposefully taking her sweet time of it. Although nopony else in their reception banquet had seemed to notice anything amiss, it was obvious to Cadance: Luna had looked completely out of sorts throughout the whole affair, and in a way that couldn't simply be explained by being dragged out of her normal night-shift schedule and made to sit through a tedious diplomatic reception honoring her niece's visit from the Crystal Empire.

So Cadance had left Flurry Heart in Shining Armor's care and given Luna a look that Cadance hoped would be interpreted as 'Do you want to talk about it? Meet me outside.' Assuming that Luna did want to talk about it – and with just a little bit of luck that she wouldn't be held up by some last-minute social call before leaving the banquet – any minute now, Luna would—

The doors from the banquet hall opened briefly, and quick but quiet hoofsteps echoed down the hallway toward her.

Cadance smiled and turned, just in time to see Luna coming down the hallway toward her. The normally regal and aloof alicorn kept her head low and glanced side to side as she approached.

“Oh! Wonderful!” Cadance said, ignoring the oddly furtive look on her aunt's face. Technically her great-great-great-great-great-great-great aunt, of course, but easier to just think of her as Auntie Luna. “I was hoping I'd get a chance to see you before heading back to the guest suites.”

“Yes, well...” Luna paused, looking around again as if checking to see if anypony was eavesdropping. “Well-met, I mean. I am also pleased. Pleased to, ah ... speak with you, that is.”

Strange ... very strange. Luna had always spoken in a rather stilted and old-fashioned way, but never so awkwardly. And the way she carried herself was wholly unprecedented – hunched down a little as if terrified, but also with a nervous energy deep inside that seemed ready to launch her into orbit on a hair trigger.

This called for caution, Cadance decided. She would have to get to the bottom of what was bothering Luna, but without setting off that explosion of nerves. If counseling an ordinary pony, Cadance might ascribe to the theory of triggering the potential nervous breakdown first, then building the pony back up afterward, but not with Luna, not with an alicorn. Luna was too powerful to risk her losing control. This would have to be done gently.

But Luna would have to be coaxed out of the silence she'd just slipped into. Cadance edged just a little closer, spoke just a little quieter: “Perhaps there's something you wanted to talk about?”

Luna immediately straightened, frowning regally. “Nothing. Nothing. All is well.”

Well, perhaps not that gentle. Cadance raised an eyebrow at her. “You've hardly spoken to anypony, you scarcely touched your meal, you haven't been able to sit still the entire time, you look like a dozen angry wildcats are ready to claw their way out of you at any moment, and right now I can see your legs trembling!”

“It is none of—”

“Oh no. Don't even start with that 'none of your concern' business.” Cadance gave her aunt a stern but understanding look. “It's everypony's concern. Things tend to go badly when the Princess of the Night gets moody.”

“MOODY?” Luna thundered, but quickly caught herself. She visibly took a few deep breaths. “No. I have sworn to all pony-kind and all that is sacred that Nightmare Moon shall never emerge again. She is vanquished for all time. I should not have to remind my own niece of this...”

Cadance nodded, coming in to briefly nuzzle her aunt's neck in a conciliatory way. “I know, I know. And I apologize. That was going too far. But you did come out here to talk to me, didn't you? Please ... just tell me what's wrong.”

“Oh, very well.”

Cadance grinned broadly, stepping back to watch every aspect of Luna's expression as she finally opened up.

“I must warn you, though, it is frightfully embarrassing.”

Forcibly suppressing the small part of her that wanted to rejoice in receiving the very juiciest of gossip, Cadance assiduously kept her expression reassuring and receptive. “I promise I won't breathe a word of it to anypony else.”

Nodding as if she knew Cadance would say that, Luna took one last deep breath to prepare herself for finally letting it out. “It is in regards to my...” She pursed her lips together for a moment, probably considering her last opportunity to keep it a secret. “My love life.” A weight lifted from her the moment she said it, and the rest came more easily. “Despite great effort and great need, my pursuits – both romantic and erotic – remain absolutely barren.”

“Well you came to the right pony!” Cadance sidled up to Luna and laid a hoof over her aunt's withers. “Love just happens to be something I'm the princess of, after all!”

“Was it not you who initiated this conversation?”

Cadance slipped off her aunt's shoulder, back to the floor. There was a hint of the old dark and mysterious Princess of the Night again. She had to consciously avoid thinking of Luna that way, or she'd be too intimidated to help her Auntie Luna. “Still, though,” she said with a bubbly optimism that was only slightly forced, “I'm sure I could help you!”

Luna shook her head. “It may be fraught with more difficulty than you suppose. I, too, had bright hopes for eventful and romantic ardors. But in reality, it seems that the shadowy princess of nightmares is too inaccessible and intimidating for most stallions. Perhaps all stallions.”

Cadance brushed away such troubles with a careless flick of her hoof. “Come on! You just need to put yourself out there. Just look at you – you're gorgeous!” Cadance herself took a moment to appreciate the older alicorn, distant blood ties notwithstanding. A tall stature that would be the envy of Canterlot supermodels, a deep chest flowing smoothly into slim and shapely body, long legs she could follow all the way up to a small but sumptuously curvaceous rump, not to mention the heavenly flowing mane and tail... Would Cadance herself ever have a mane like that? Was it an effect of being an alicorn, or did it come from association with the heavenly bodies? No – wait – the important part here was Luna's heavenly body ... and finding a stallion to satisfy its needs. “I'm sure that as soon as the stallion understands that you're interested in him, he'll be ecstatic to give you all the attentions you could ask for.”

“Oh, that I could dream it so.” Luna rolled her eyes and blew upward into her mane. On a normal mane, that would have blown the forelock out of her eyes, but with her ethereal one, it only made the twinkling stars ripple a little. “A mere two days ago, I approached a comely Canterlot noble, and I was quite blatant with my intentions.”

“And ... how did it go?”

Luna glowered at her. “He said I was too old.”

Cadance sniggered. Try as she might, she couldn't suppress that tiny snort of laughter.

Of course, that only intensified Luna's dour glare. If looks could kill, half of Canterlot would need to be evacuated, lest they be too close to the one Luna was giving Cadance now.

Slowly, Cadance regained mastery over herself. “Well, Auntie ... in fairness, you are pushing what ... three thousand now?”

The look in Luna's eyes fractured. Real pain showed through there, behind the righteous indignation.

Seeing that, Cadance rushed in to hug her aunt tightly. “And you haven't aged a day! I don't know what that little prick was talking about. Any stallion would be the luckiest in the world to get so much as a salacious look from you!”

Luna hugged her back, just as tightly. When they separated, she was smiling wanly. “Flatterer.”

Returning her look with a cutting stare only somewhat marred by her wry smile, Cadance riposted, “Old maid.”

“Untrue!” Luna said with a slight giggle – an actual giggle! She was finally loosening up a little! “I am no maiden. I had more than my fair share of amorous encounters before...” She looked down at the floor. “Before that unfortunate event a thousand years past.”

“Don't you worry, we'll get you—”

“Truthfully, I despair of ever finding any satisfaction. I know of no stallion who would not shrink away and wither at the sight of an alicorn princess.”

“I know one!” Cadance volunteered.

Luna looked up sharply. “Who?”

“Shining Armor, of course.”

“Well, yes, of course.” Luna drooped back down. “But that does me no good.”

“Why not?”

Without lifting her head, Luna peered up at Cadance, staring up at her as if she'd suggested handing over responsibility for the moon's safe travel to Pinkie Pie.

Cadance looked right back ... pointedly, and not giving an inch. She would force Luna to make the next move. She'd wait this little staring contest out however long it took.

It didn't take long. Luna snorted daintily. “You do recall that he is your husband, do you not? And also the father of your child. He is not available.”

“Well, you can't keep him. But I could always share a little.”

“You...” Luna's eyes widened. “You would do that?”

“Of course!”

“And he...?”

Cadance grinned lasciviously. “Trust me, he's definitely going to be into it.”

“Never in my long life have I ever seen such generosity!” Luna stood up tall her hooves prancing in place a little and her sides heaving with excited breaths. “I ... I do not know what to say!”

“How about you start by saying what time you'd like to come by our guest suite and get a taste?”

Luna calmed a little, but only a little. “I could not impose, but... It has been such a very long time, you understand... Would it be uncouth of me to want it as soon as may be?”

“Tonight then, right after sunset.” Boldly now, Cadance reached up and caressed a hoof through Luna's twinkling mane and said sweetly, “See you then.”

As Cadance left to arrange things, she couldn't help but look over her shoulder to see Luna – the 'dark and mysterious' Princess of the Night – blushing and fidgeting her legs like a filly in her first heat. Cadance briefly wondered if Luna would be the type to clop herself silly while she awaited sunset.

She couldn’t spend too much time on such speculations, though. The banquet had already run long, and sunset was not far distant. And she still needed to arrange a sitter for Flurry Heart, locate her husband, and ease him into the idea of a ménage à trois. Little details such as exactly who the other mare would be ... that could be left out, of course. No point in getting Shining Armor too worked up and intimidated before things even started. A surprise. Surprises were always fun. She'd just tell him that the mare's identity was a surprise, and that he could trust her to find one he'd enjoy.

* * *

Cadance lounged sidelong on her suite's bed, grinning as she saw the light from the window fading orange, then red, purple, and finally a dim, dim blue. A tad faster than usual? Well, that was understandable. Sunset was done. Flurry Heart was safe with one of the best foalsitters in Canterlot. And her husband was ready ... very ready.

She was more or less in his lap as he sat on the edge of the bed, and she idly stroked his quite-erect cock with one hoof as she awaited her Auntie Luna's arrival.

Shining Armor, in turn, stroked one of his hooves through the back of her mane. He was brushing the curl out of it, but she didn't mind. It felt good to have him touching her like that. “So who is she?” he asked again.

“I told you, it's a surprise.”

“Do I know her?”

“Oh ... you've met.” She looked up at him with a little smirk.

“And...?”

“And you'll find out when she gets here!”

Shining stopped caressing her mane for a moment to stroke his own chin instead. “So ... it's somepony I know really well...”

“I didn't say that.”

The smugness was obvious in his voice. “I think I know who it is. Let me narrow it down a little bit – she's an alicorn, isn't she?”

Cadance looked away before her face could betray anything.

Thankfully, even though he saw the confirmation of his question perfectly well, he seemed to follow it to exactly the wrong conclusion. “I knew it!” He began stroking her mane again. “Oh Cadance, you dirty little Love Princess, you are so good to me! How did you know I've been wanting her so badly? How did you get her to agree to it?”

A knock came from the door.

The way they were sitting on the bed, they faced directly toward the door. Anypony who came in would get an immediate eyeful of Shining's erect cock. Cadance decided to risk it on the chance that the pony knocking was who she thought it was ... rather than some palace servant. “Come in,” she called, loudly and clearly.

As the door opened, Shining called out happily, “Twil—” He choked. “Prin— Princess Luna?”

Luna came inside, shutting the door behind her with her magic. And she blushed so adorably at the sight of Shining and his cock so readily awaiting her. “I see you have been, ah...”

“Oh yes,” Cadance confirmed. “I've been keeping him nice and ready for you.”

“Ready ... for Princess Luna?” Shining's mouth gaped. Cadance was tempted to reach up and shut it for him.

Luna took half a step backward. “You are ... interested in me, are you not?” She stole one glance back over her shoulder, no doubt making sure she could still make a hasty escape if the situation ended up too embarrassing to endure.

“Y-yeah!” Shining stammered. “I mean, um, yes ... of course. I'm... It's just a bit of a shock.”

When Luna looked into Cadance's eyes, her deep-seated need was obvious to see. “So, given that he is obviously already ... prepared...” Luna paused, pursing her lips. Was that a gulp?

“Yes...?” Cadance prompted. She couldn't help it – seeing Luna like this was just too much fun.

Luna's blush deepened, and she looked away. “Shall you leave him alone with me immediately, or...?”

“Alone with him?” Cadance stroked her husband's cock a little more vigorously. “Why would I leave?”

Looking back up at her, Luna tilted her head slightly to the side. “Because, well ... we did have an arrangement, did we not? I thought—”

“We had an arrangement to share him.”

Luna stared, dumbstruck.

“So ... do you want to share or not?” Cadance bent down and gave Shining's tip a dainty little lick. More could come later. For now, she just savored the musky, salty taste of his pre-cum. “I promise you'll enjoy every moment, and there's plenty of him to go around.”

With her legs scarcely able to hold still and her tail already beginning to flag up high behind her rump, Luna gave a tiny, tense nod.

When Cadance beckoned her aunt over with a curl of her hoof, Luna rushed across the room. Her gangly awkwardness would suit a teenage filly better than an ageless alicorn. She ended up right in front of Shining, reaching her hoof up toward his cock, but there she hesitated, her hoof trembling and just on the verge of touching him.

“Go on,” Cadance told her, “you can touch.”

“It has just been so long since I...” Luna took a deep breath, then reached her hoof just a bit farther. The soft inner frog of her hoof came to rest gently against the curve of Shining's shaft. She bit her lip slightly, her eyes going a little unfocused as she slowly stroked down his length. She looked up into Shining's eyes, then over at Cadance. “He ... he is wonderful! So firm and so thick. It has been ages since I have seen the like.”

“Thanks,” Cadance said with a genuine smile and a wink. “I'm rather partial to him myself.” She bent down again and suckled Shining's tip as Luna began stroking the rest of him with more confidence.

Shining groaned slightly, his hoof moving down from Cadance's mane to the curve of her back. “Oh wow, Honey ... that feels nice.”

Cadance came back up, artfully leaving a little trail of spittle between her husband's tip and her own lips in a way she knew would draw the eyes of both of them. But she didn't respond to Shining. She got compliments from him about her blowjob techniques all the time, and there was something – somepony – far more novel here tonight. “Would you like a taste, Auntie Luna?”

But Luna didn't answer. She was entirely absorbed in her task, curling her hoof halfway around Shining's cock now as she stroked him. Her wide, star-sparkling eyes were full of a look of intense longing, and her mouth was open, her pink tongue hanging out just a little.

Seeing Luna draw closer to Shining's tip, Cadance sat back for a moment and just let it happen naturally. Only ... it didn't. Luna came so close that Shining must have been feeling her breath, but she hesitated there, seemingly unable to cross that last little bit of distance.

Thankfully, she had her niece there to help her along. Cadance placed her hoof on the back of Luna's head and gently encouraged her.

Luna's eyes drifted closed as his tip slid past her lips. Her tail rose even higher behind her, the base of it shooting straight up before the rest spread out into its starry plume.

“There you go,” Cadance cooed, pushing her down a little farther. “Lovely isn't it?”

“Mm mmnmmm mmmm.”

Bobbing Luna's head up and down with one hoof – more down than up – Cadance reached with her other and caressed Shining's balls. She loved the full, firm feeling of those smooth orbs against her hoof, loved gently hefting the weight of them, and really loved the idea that they'd soon be emptying themselves for Luna.

And once she got started, Luna didn't actually need all that much encouragement. She was pushing herself down far more than Cadance was pushing her ... but Cadance wasn't done yet.

Leaning in close, Cadance kissed her husband, distracting him from the view he'd been staring at: his cock disappearing bit by bit between Luna's luscious blue lips. Cadance slipped her tongue into Shining's mouth and at the very same moment pushed Luna down deep on his cock.

Luna took it like a champ, not resisting at all as she was shoved downward. She even moaned a little.

Cadance broke the kiss, but just barely, keeping her lips almost in contact with his. “So, how does Her Royal Highness's throat feel?”

Shining gave a long, shuddering moan.

“That good, hmm?”

Without prompting from Cadance, Luna plunged all the way down on him, taking him to the hilt. Shining's whole body jerked a little bit, and he gasped deeply.

Cadance had to admit that Luna knew what she was doing. She may have been going without for quite a while, but she was certainly no amateur.

She did have her limits, though. After a few moments of swallowing Shining's cock all the way down, Luna suddenly pulled herself back up off of him. She heaved in deep breaths, her lips dripping spit back down onto him.

“Easy there, Auntie. There's no rush.”

Holding Shining's cock against her face and stroking it with both hooves as she caught her breath, Luna looked up at Cadance. “How am I to exercise restraint now, of all times? You have no idea how badly I have needed this!”

Without a moment wasted waiting for a response, Luna took him in her mouth again, quickly working her way down, down, down with every bob of her head until her lips kissed his sheath again.

But she came up even sooner this time, coughing a little as she struggled for breath.

“Here,” Cadance said holding up his balls for her, “why don't you let me take a turn and get a taste of these babies instead?”

Luna plunged her face down again, but this time without Shining's cock inside. Well, not entirely inside, at any rate. She still slid her open lips all the way down the side of his shaft.

Once she'd gotten low enough, she went straight to work on his balls, slathering them with her tongue and rubbing her muzzle all over their curves.

Cadance took advantage of how available her husband's cock suddenly was by taking it into her own mouth. She sucked him seriously this time, none of the little teasing she'd done earlier. Now she calmly and skillfully worked her way down his generously-sized shaft, licking every curve and vein along her way.

It pleased her to no end to hear Shining moaning even more enthusiastically for her than he had for Luna. She still had her magic tongue! And she was more in practice, too. Taking her husband deep, deep inside her throat came with none of Luna's gasping and theatrics. Shining's length nestled easily into her throat, as if that was exactly where it belonged. Cadance smiled to herself slightly, even though her lips were tightly stretched around his girth. Shining's cock did belong here inside her. No matter who she saw fit to share him with, this was the place he belonged.

And as if Cadance wasn't already enjoying herself enough already, Shining's hoof slowly made its way down her back. She knew exactly what he was up to, and she lifted her tail up and out of the way in anticipation. When he tried, he could stretch just far enough to reach around the curve of her pretty pink rump and slip the end of his hoof down between her cheeks, rubbing her pussy.

And yes, there it was. Cadance moaned appreciatively around his cock as she felt the familiar tickle – the soft inner part of his hoof gently rubbing her pussy lips. She winked for him, right against his hoof, and without even trying to. Her pussy was eager and ready to share a little bit of what her mouth was already enjoying.

Adding to her pleasure, she got dinner and a show. As she bottomed out against Shining's sheath, she was treated to an excellent view of what Luna was doing ... and Luna was doing such wonderful things. Her dark blue face was buried underneath Shining's pale pink balls at the moment, but she soon worked her way up, licking all the way from their underside, up the crease between them, and all the way up to his sheath where she very nearly kissed against Cadance's lips. But then she was back down again, nuzzling up intimately close, tucking her nose into the gap between thigh and balls, rubbing her cheek along their full, bulbous curves. Luna's eyes rolled up dreamily as she took in a deep whiff of Shining's scent, and Cadance could see the way it made her aunt's fur stand on end.

Well, if Luna was that desperate, why not let her get a little satisfaction? It was time she got what she came for!

Cadance finally came up for breath, calmly sucking in deep lungfuls of sweet, cool air after the little she'd been able to squeeze past Shining's steamy-warm cock. She didn't get a chance to invite her aunt, though.

Luna had already launched herself upward and was scrambling onto Shining's lap. “Delay me no longer!” she said breathlessly. “I must have him!”

Licking her lips, Cadance stared at the way Shining's tip prodded against the taut curves of Luna's rump. His cock pressed against Luna every time she hastily shoved herself down on him, but each time, it didn't quite penetrate. It slid over Luna's winking pussy lips instead of inside them, it smeared spit and pre-cum over her black-speckled fur, and it squeezed up between her firm cheeks, but it never ended up quite where Luna so obviously wanted it to. Her dark blue pussy lips winked open over and over again, proudly thrusting out her clit and a hot pink triangle of need, but she was so sloppy in her haste that she couldn't get things positioned right.

Cadance could though. And while she could have done so with her magic, or at least her hooves, what was the fun in that? She bent back down and held Shining's shaft between her lips, tonguing him a bit as she held him steady and helped guide his tip to just the right spot.

“Yes!” Luna cried out as her pussy lips spread open over his tip. “Yes ... yes! Oh my stars yes!”

Cadance was treated to an up-close and personal view of her husband's cock gradually slipping into another mare's pussy, and to her surprise, she found the sight his mottled pink shaft sinking into those winking blue lips even more arousing than Shining's continuing efforts to please her with his hoof.

Oh, this was delicious, and not just because of the juices that were dripping down into her mouth. The slight inward and outward stretching of Luna's pussy as she worked her way down his shaft, the combined music of both of them moaning out their pleasure, seeing the familiar contours of his cock slip irrevocably into another mare... It all combined to make Cadance reel with erotic bliss. She slowly worked her mouth lower against Shining's cock, giving up more and more of it to Luna.

When Luna's pussy lips bulged outward to accommodate Shining's medial ring, Cadance suddenly realized she wouldn’t be able to keep going in this position. Luna's legs would block her access. She had to give up the attentions of Shining's hoof under her tail, but her own pleasure could come later. For now, she slipped off the bed and came up between Shining's outstretched legs.

There, she had the perfect opportunity to lick the base of his shaft ... until it, too was squeezed wetly into Luna's pussy. Cadance finally dropped down to give each of his balls loving individual attention, bathing the warm orbs with her tongue in order to tease out the best load she could for her Auntie Luna.

For her own part, Luna soon gave free rein to her enthusiasm. Pounding herself down on Shining's cock with absolute abandon, she picked up her pace more and more. Her tail arched up high behind her back, but the end of it flowed down over Cadance's body, swishing to and fro with her ever-more-vigorous motions.

Cadance just smiled, glad that her aunt was enjoying herself, even as love-juices spattered intermittently down. It brought up an odd, tingling naughtiness inside her to be licking another mare's juices off of her husband's balls. The lewd slippery sounds and their adulterous moans made her pussy wink with urgent need. If only there was some other stallion here to complete this perfect image of infidelity ... Well, perhaps next time.

For now, though, Luna's pace was faltering. Even as her deep-pitched yet feminine moans grew to a crescendo, the pace of her frantic bouncing became erratic, losing all rhythm. Luna's dark blue legs trembled, threatening to give way at any moment.

Cadance extracted herself from underneath the other alicorn before that could happen. She had better ideas about where this should go than seeing them all in a tumble on the floor.

Getting back up on the bed next to Shining, she whispered into his ear, “Shiney, dear, do you remember that thing I told you I liked so much, when you suddenly rolled me onto my back and took charge?”

“Uh ... huh,” he managed to grunt out. His teeth were clenched, and his eyes would probably have been squeezed shut just like Luna's if he wasn't so focused on staring at her bouncing body.

“Give Auntie Luna a taste of that, won't you?”

Shining nodded. Reaching out with a quick strength impressive even by alicorn standards, he grabbed onto Luna's body and held her tight, preventing her last efforts to bounce on his lap.

Luna opened her eyes and squealed – a surprisingly girlish sound – as Shining swung her around and rolled up on top of her. He let his legs fall off the edge of the bed, standing upright between Luna's thighs.

Once Luna realized what was happening, she grinned almost manically and arched her back against the bed. Cadance had to admit as she stared that her aunt had a magnificent body, especially when she stretched out that long, lean belly of hers.

Cadance couldn't resist. She didn't even wait for Shining to start thrusting before she dove down and began kissing and nuzzling that gorgeous blue belly, quickly working her way downward. She'd already reached Luna's dainty little teats and began suckling them by the time Shining began to move.

And Shining held nothing back. He gave powerful thrusts of his nice, big cock into Luna's desperate pussy. The bed shook with each one of them, and Cadance could swear she felt the slight bulge of it rippling up and down Luna's delicate underbelly.

As Luna's moans grew in intensity again, Cadance ventured even more daringly. From Luna's teats, she licked a delicious trail through the soft, delicately fuzzed space between Luna's thighs until she finally reached her true destination. There it was – an unassuming-looking blue bulge, occasionally showing a flash of pink as Luna's clit winked out of it. Just beneath, her husband's cock slid rapidly in and out, coated with syrupy juices.

Cadance paused only to lick her lips before diving that last little bit down and planting her tongue on her Auntie Luna's clit. Of course, there was no way to do that without also letting her tongue slide over the top of Shining's cock, but she was sure he wouldn't mind.

Luna's moans quickly grew into cries of passion squeaked out between deep gasping breaths. Cadance felt the body underneath her grow stiffer and stiffer, and Shining couldn't thrust nearly as far in and out as Luna's hind legs clenched tightly around his back.

With any luck, though... Yes!

With a stunning suddenness, Luna went absolutely still and quiet. For that brief moment, everything froze. Even Cadance paused her licking, stopping with her tongue bridging the slight gap between Luna's clit and Shining's cock.

“YES!” Luna screamed out in her full Canterlot Voice. Her body suddenly reanimated, jerking against the bed as her belly heaved up and down. Cadance was in the perfect position to see – and taste – the sudden surge of marecum flowing out over Shining's cock. She would have almost felt sorry for her husband being squeezed so tightly by Luna's pussy and her alicorn-strength legs ... if he wasn't in the middle of living out every stallion's fantasy.

When Luna's exhausted body finally flopped down limply against the bed, Cadance rose as well. She didn't go very far, though. All she had to do was lay her own body belly-to-belly against Luna's and lift her tail up over her back. Her pussy was already winking non-stop, and Shining was sure to see her dribbling need.

“Your turn?” Shining asked.

Even though it must have been incredibly obvious, Cadance was pleased with him. If there was one thing she wished she could tell every couple as the Princess of Love, it was that good communication was the key to a good relationship – and to good sex. “My turn,” she confirmed, smiling wickedly to herself and swaying her hips slightly side to side in the way she knew drove him crazy.

It took no time at all for Shining to pull his cock out of Luna and line its slippery tip up with Cadance's pussy instead. When he pushed forward, her entrance spread open easily for him. Her pussy welcomed its dearest friend with the warmest, wettest embrace possible, and Cadance shivered with delight at the familiar feeling of her own body accommodating the shape of her husband's cock inside. He was able to go all the way in on the very first thrust, aided by her copious liquid arousal and the slick remnants of Luna's orgasm. When his thighs bumped into her ass cheeks, she reveled in the feeling of the other mare's orgasmic juices spreading deep inside her.

That wasn't the only place Cadance was interested in spreading Luna's marecum, though. Luna's open mouth, still panting from her exertions, was all too alluring. Cadance only had to dip her head down a little bit in order for their lips to meet, and she did, smearing Luna's own juices in the sloppy illicit kiss.

Despite no doubt sensing her own tangy taste, Luna seemed to only awaken to the fact that her niece was kissing her once Shining started thrusting again. When Cadance moaned slightly into her aunt's mouth, Luna's eyes suddenly opened to see what was happening to her.

For a brief moment, she stared up in shock, but then her eyes drifted mostly-closed again, and she pressed her body up against Cadance's.

Cadance reveled in the feeling of the other mare's warm belly fur against her own, even as her husband filled her with his cock. This was no time to care about vanishingly distant blood relations. Not even a time to worry about who was married to whom. They were simply two mares in need, sharing a wonderful stallion and sharing each other. Cadance eagerly reciprocated when Luna hesitantly ventured her tongue into the kiss, and she adored the tender feeling of Luna stroking her mane just like Shining had.

And all the while, Shining rutted her like a mare in heat, giving it to her every bit as good as he'd done for Luna. His cock felt amazing rippling over her inner walls, in and out. Even though she knew every vein and curve of her husband's cock, it all felt brand new tonight, as if she'd never had him before. That tingling warmth inside her was growing, and it was growing fast.

But she didn't end up taking that straight, short path to orgasm. Once Luna began to revive, her moans must have given Shining other ideas, because he pulled out and plunged his cock back inside her pussy instead.

Cadance didn't get much chance to get jealous of the other mare's pleasures, though. Because with almost every thrust, Shining began switching back and forth between the two of them. Cadance and Luna shared their juices and the warmth of each others inner depths freely between each other, oh-so-helpfully swapped back and forth by Shining's lovely cock.

At first, Cadance was pressing closer to Luna just to give Shining an easier time of it, so he'd spend less time uselessly outside either of them and more time in her. But once she slipped one leg underneath one of Luna's, she was actually able to get their two pussies in direct contact with each other. She felt it with a sudden jolt – even though Shining was currently thrusting back into Luna's pussy, she felt something warm and firm prod up at her own clit. It was Luna's clit, winking upward and kissing her own!

Cadance was so enthralled by that wonderfully intimate contact that she didn't notice Shining moving back up to her ... not until his cock slid perfectly back inside her once again.

She broke her kiss with Luna at that point, throwing her head back with a throaty moan. Feeling Luna's clit pulse against hers was almost as good as being licked down there, and with Shining's cock filling her besides...

Her climax was coming and coming soon, she knew it now. Even when Shining briefly switched back to Luna for a moment, she still felt it building. Not that her lack of him was a problem that lasted long – Shining must have sensed her approaching orgasm because he was starting to give her a lot more attention than Luna, almost completely ignoring the other mare.

That little bit of loving consideration was all it took to finally drive Cadance over the edge. With a filly-like squeak, she instinctively gripped tightly around Luna's body, pressing her muzzle against Luna's neck and breathing in deep lungfuls of her delicate scent. Cadance's pussy danced and squeezed around her husband's cock, milking him for all he was worth, even though she knew he'd never be so rude – Luna was their guest, and she deserved his cum, at least this time.

That didn't stop Cadance's body from trying, though. She at least gained some satisfaction from hearing him groan, from feeling him reach down and squeeze her pink ass cheeks. It must have been so hard for him to hold back. Oh, what a good stallion! She'd have to reward him later ... if she could possibly think of something that was a better reward than he was already getting tonight.

As Cadance's orgasm ebbed and she relaxed her grip, Luna slid out from underneath her and Shining slid out from inside her. She didn't mind too much. She was still adrift on fluffy pink clouds of post-orgasmic bliss.

She watched with half-absent mind as Luna stood with her front hooves braced against the bed, as Shining came up behind her, his glistening wet cock swinging eagerly beneath his belly. The look on Luna's face as he mounted her tickled Cadance's fancy – she could tell exactly when his cock spread Luna's pussy lips open and pressed inside. The slight widening of her eyes, the way her pink tongue lolled out of her mouth ... it sent a fresh shiver of aftershocks running through Cadance's body, just from the memory of how that felt.

As Shining rutted her, Luna gradually lost her upright posture. First she bent her forelegs a little, but she couldn't hold them like that for long. Then she let them fold entirely, almost pressing her chest against the bed. And finally she lost all control whatsoever, willingly letting her face press into the bedsheets as Shining pounded into her upraised rump from behind.

By that time, Cadance had recovered enough to get up and rejoin the fun. She rose to a sitting position on the bed, high enough to lean up and kiss Shining as he rutted her aunt. That wasn't enough to satisfy her, though – she needed to help.

That ended up taking the form of her reaching one hoof out behind Shining, grabbing his nice muscular ass, and helping him push even harder into Luna's welcoming pussy. With her free hoof, she rubbed her own pussy, quickly leaving her hoof soaked in her own arousal and post-orgasmic juices.

Shining, meanwhile, was beginning to depend more and more on his wife's helping hoof. His thrusts grew longer, deeper, and his breath came in strained gasps.

“I can feel it!” Luna suddenly cried out. “His tip has flared to its utmost!” She pressed herself back against him, helping him get as deep as possible inside her. “Fill me, virile stallion! Hold nothing back!”

Cadance bit her lip slightly and shivered at the idea of her Shining emptying himself inside Luna – impregnating another mare, right in front of her. She would see it happen! Her hoof quickened its pace against her pussy lips almost without prompting, and she stretched her long neck out to whisper in Shining's ear, just loud enough to be sure Luna would hear it, too: “You heard her, stud. Cream her like you mean it. Make her pregnant for me!”

She slid her other hoof down from his ass cheek and around to feel his balls as they began clenching, and she fired off that one special spell of hers, the one that would sneak its way up his ass and tickle his prostate mercilessly. That was a little stunt she only pulled off on special occasions, when she wanted him to empty himself of every last drop.

Cadance could feel it when Shining's balls pulsed. She could see just a little bit of his cock outside of Luna's pussy as powerful throbs ran through it. And she could imagine – oh could she ever imagine – the marvelous feeling of all that potent cum rushing in great spurting surges into her pussy. She'd felt that so many times before, but this was Luna's turn. It was Luna's turn to feel that growing pressure, that spreading warmth, and that wonderfully gooey flow that seemed to fill up so much more than just one's womb.

Cadance's own body suddenly clenched up again, a smaller second orgasm shooting through her and dripping juices down on her busily-moving hoof. Yes! If she closed her eyes, she could almost imagine that it was her receiving the full potency of her husband's orgasm.

She wasn't so lost in her own imaginings that she didn't hear Luna cry out in another orgasm of her own, though. And somehow, that only intensified Cadance's feelings. The fact that some other mare was receiving her husband's gift was somehow just as titillating as the thought of getting it herself. And the idea that he might be making her pregnant, right before her eyes... She suddenly snapped her eyes open, determined to see it. The image of her husband's white-furred body mated up against Luna's black and blue curves seared itself into her memories, saved away for many times in the future. She knew that this image would keep coming back to her every time she clopped herself now, and she was so looking forward to it that she was tempted to start hoofing herself again this very moment.

But as Shining relaxed and began to pull out of Luna's well-sated pussy, Cadance suddenly found a much more urgent task. She darted down to the edge of the bed, squeezing into the growing space between her husband's thighs and Luna's ass.

She was just in time to catch the excess of Shining's orgasm. She took as much as she could manage on her tongue, eagerly holding it out to catch the first fat drop of cum in her mouth and swallowing it down ... but between Shining's now-limp cock and Luna's winking pussy both dripping out long white lines, a great deal of it ended up draped over her cheeks and muzzle, even a little bit in her mane.

It was still easy enough to collect a generous mouthful, though, even after what she'd initially swallowed. And she had just the place for that mouthful.

As Shining staggered back and fell into a nearby lounge chair, Cadance climbed back up next to Luna on the bed.

Luna took one look at Cadance's cum-draped face and seemed to immediately know her intentions. And, happily, she seemed perfectly amicable to those intentions. With a satisfied, blushing smile, Luna rolled slightly to her side to better receive the kiss, holding her head a little lower than Cadance's so that the warm mess flowed mostly down into her mouth. And even though most of it ended up dripping between their lips over each others faces and onto the bed, Luna still got more than enough to give her an adequate sampling of what her pussy had just received.

When they finally separated, Cadance cleared the sticky strand between their lips with a swipe of her hoof, then used it to clean her face a bit ... though it mostly just smeared the cum around her pink fur, rather than removing it.

Cadance grinned at her aunt and took a comfortable position lounging next to her. “That was very bold of you, letting him finish inside like that.”

With a deep sigh, Luna seemed to sink deeper into the bed. “Would you exercise caution if you had been without satisfaction for over a thousand years? I think not.” She shifted her legs a little, no doubt reveling in the still-spreading warmth deep inside her. “And the risk is minimal in any case. As I am sure you know, it is nearly impossible to impregnate an alicorn.”

She didn't know... How delicious! Cadance leaned in close and whispered into Luna's ear, “You forget, Auntie – Shining Armor has a history of knocking up alicorns.”

Luna's eyes went suddenly wide.

Smirking, Cadance reached down and rubbed the gentle curve of Luna's belly just above her teats – was it a bit more curved now, or was that just Cadance's imagination? “I hope you enjoy his little gift.”

Luna looked down and rubbed her belly herself, just as Cadance had. Her cum-covered mouth gaped open. “I ... I shall.” She blushed, more intensely than she had all night. “But just to be sure that it takes ... perhaps we could do this again tomorrow night?”

Cadance looked back over her haunches at her husband. She could well imagine the scene he must be seeing: two lovely alicorn rumps lying together on the bed; one black black-spotted, moon-emblazoned, pussy still slightly open, and drenched with cum; the other pink, showing her crystal heart mark over the curve of her ass, and her pussy dripping clear juices while still winking desperately to be treated the same gift as the other. Grinning because she already knew his answer, she said,
