Mediator
Prince Bolero sat on his bed, smiling kindly at his wife and his brother-in-law. He brushed a lock of his perfect mane out of his eyes, and spoke. “I’m sure you both know why I’ve brought you here tonight.”
Gleaming Shield and Dusk Shine both nodded, but they avoided his eyes, ashamed. Bolero’s gaze held no judgement.
“I know that you bear incestuous desires towards each other. While I am the Prince of Love, I cannot in good conscience allow sexual relations between you. It is depraved, it is against our customs, and I’m sure you know what Equestrian law has to say on the matter,” he said. “But at the same time, I cannot allow two wonderful ponies with such love in their hearts for each other to suffer like this. Come closer, my dears.”
Dusk Shine walked over. He was slight of frame and neatly groomed, his purple coat almost glowing in the moonlight. His sister followed neatly, muscles flexing beneath her shining white coat, unsure but undaunted.
“Now, move closer until your lips touch each other,” said Bolero.
Both siblings swallowed, gazing into each other’s eyes, closer and closer, inches away from fulfilling every hidden desire--”
“Stop!” Bolero darted forward, his face coming between the two of them. Dusk and Gleaming froze, their puckered lips pressed against the prince’s cheeks. “Siblings kissing on the lips is forbidden!”
Dusk and Gleaming tried to rear back, but found their heads pushed close by Prince Bolero’s wings. “However,” he said, “Nothing forbids Gleam from kissing me and then me kissing Dusk, and vice versa. Let’s try that.”
He turned to his wife and kissed her. She squeaked into his mouth, her lips hard against his before she relaxed and returned the kiss. A second after she slipped her tongue inside, Bolero broke the kiss. “And now you, Dusk.”
Dusk’s eyes went wide as his former babysitter--and former secret crush--kissed him. The prince copied every aspect of his wife’s kiss, tense lips relaxing, tongue slipping inside, breaking off. He looked between the pair of them. “And how was that?”
They both nodded excitedly, forgetting to speak. Bolero laughed, and kissed Dusk again. Dusk was more prepared this time, slipping a hoof around Bolero’s head to hold him close, moaning softly into the kiss, playing his lips gently against Bolero’s. The prince grinned as he broke away.
“Well, you didn’t learn that by practising on your hoof. Not bad for a bookworm!”
Dusk Shine blushed. “Sometimes I, uh, practice with Rainbow Blitz...”
“It shows.” Prince Bolero turned and gave Gleaming Shield an identical kiss, holding her close, letting her feel everything that her brother just gave to her husband. When she returned the kiss, she was wild, passionate, sticking her tongue forward like a horny teenager, which Bolero in turn did to Dusk Shine.
They continued in this manner for some time, increasing in passion and intensity until Gleaming Shield and Dusk shine were both pawing at Bolero, their eyes lidded, cheeks flushed, panting helplessly.
“What do you each desire most?” asked the prince. The pair hesitated to answer, but with some nudging they spoke.
“I... I want to touch Duskie,” said Gleaming Shield.
“I want to hold Gleam,” whispered Dusk Shine.
“I want to nuzzle his neck.”
“I want to nibble her ear.”
“I want to suck his horn!”
“I want to lick her teats!”
“I want him on top of me!”
“I want to be inside her!”
“Take me!”
“Oh, Gleam!”
The unicorns threw themselves at each other, but their erotic embrace was blocked by a pair of pink wings between them. They pawed hopelessly at the feathery fluff as Prince Bolero clicked his tongue at them.
“My dears, please, incest is verboten. Not allowed. Forbidden.” He pushed the despondent unicorns apart, until he was sat on the bed between them once more. “However,” he said, gesturing between his legs, “there is no law that forbids two siblings from sucking the same cock.”
Gleaming set to work with military precision, taking the head of Bolero’s half-hard dick into her throat, nursing it with her lips and tongue. Dusk was more hesitant.
“I, um, I h-haven’t,” he stuttered, “I’ve n-never given oral s-sex before. I might not be very good at it...”
Prince Bolero gazed into Dusk’s wide eyes. “You’ve grown into such a handsome stallion, Dusk,” he said, trailing a hoof over his brother-in-law’s cheek. “I don’t think I’ve ever seen a stallion with lips as pretty as yours...”
Dusk Shine blushed deeply. “Th-thanks...”
“Have you ever thought about it? Wrapping those perfect lips of yours around another stallion’s thick cock?”
“Yeah...”
“Look at the tip, Dusk.”
The unicorn looked down. Gleaming Shield was licking the prince’s balls and massaging his cock with telekinesis, sending rings of firm pressure up the shaft. Her attentions were pushing precum out of the tip. There was more precum than Dusk had ever seen, it wasn’t just welling up in a tiny bead, it was pooling up and leaking down the sides of the shaft. His breath caught in his throat.
He stuck his tongue out, lapping at the salty, musky liquid. He looked up at Bolero, an unbroken line of precum between the dick and his tongue. “Lack thith?” he asked.
Prince Bolero marvelled at the svelte unicorn. “Yes,” he said, his voice shaking a little, “just like that.” He pushed Dusk’s head down, groaning softly as the stallion took the entire head in his mouth. Brother and sister continued their blowjob, sucking the tip, licking the shaft and balls, taking turns to service each part, nervously switching from spot to spot.
“It’s good that you know how to share, but teamwork is important too,” said Prince Bolero, breathlessly.
They nodded and began to work in tandem, Dusk licking the balls as Gleaming sucked the tip, both licking their way up the shaft, timidly meeting eyes with each other as they reached the head together, licking and even nibbling at the base as they sent matching waves of telekinesis up and down the shaft.
“You can get a little closer to each other, darlings. There’s nothing wrong with siblings nuzzling...” murmured Prince Bolero.
He didn’t need to tell them twice. They began to kiss and suck at the tip immediately, their cheeks pressed together closely, horns touching, almost making out over the head. The prince chuckled softly. Their tongues were touching a little too often to be called ‘accidental,’ but it did feel wonderful...
Dusk looked at his sister, and nervously mumbled over half a mouthful of cock. “Am I doing this right?”
Gleaming Shield smooched the shaft, and smiled warmly at her brother. “You’re doing great, little brother. I’ll show you what else he likes. Watch this...” Her horn lit up, and gentle telekinesis began to massage Bolero’s balls, making him sigh with pleasure. Her magic cut off abruptly. “Now you try!”
Prince Bolero tensed up, well aware of the magnitude of Dusk Shine’s telekinetic power, and relaxed as the same soft magic returned to his sack. He didn’t see his wife’s evil grin as her horn lit up once more.
“Solaris!” He cried out as Gleaming Shield pushed a thick tendril of magic into his ass, twisting and pulsing as two mouths returned to his shaft. “Guys, if you don’t stop, I’m--”
“Hm?” Dusk looked up at him with those wide, innocent eyes, his cute tongue pressed against the tip of his cock.
Bolero came, his back arching as cum sprayed out of his shaft. Dusk caught three heavy spurts on his face, taken completely by surprise, before Gleaming grabbed the dick and sucked on the twitching head. He always came in prodigious quantities, and his wife’s cheeks bulged before she could swallow the second mouthful. She passed it back to Dusk, now prepared, who scrunched his eyes tight as he drank down jets of thick, salty jizz, until his wife took it back. They passed his cock back and forth for almost a minute before he was spent. He fell back onto the bed, allowing Dusk a chance to clean off his face, and Gleaming a chance to lick the last droplets from his shaft.
A minute later, Prince Bolero slid off the bed and stretched out. As the tension seeped from his muscles, he closed his eyes and cast a spell. His softening, sensitive shaft returned at once to stiffness. He gave a small sigh of satisfaction at the sensation of the spell, and then looked back at the blushing siblings, smirking.
“Okay, I think we’re getting to the crux of the matter,” he said. “You two want to fuck each other, yes?”
Dusk Shine and Gleaming Shield looked at him, looked at each other, and then looked back at him. They nodded, ashamed.
“Fortunately for the pair of you,” Bolero continued, his voice like syrup, “I have the perfect solution. Gleam, my love, lay down on the edge of the bed with your hinds spread wide. Dusk, my dear, get behind me.”
Brother and sister did as instructed, Gleaming’s inner thighs rippling with muscles as she spread her legs, Dusk cautiously approaching the prince’s backside, getting a whiff of cologne, shampoo and sweat as Bolero’s thick, pink tail brushed his cheek.
Bolero moved between his wife’s legs, his cock inches from her groin. She gazed up at him, both curious and imploring. He bent down to kiss her cheek, and then looked over his shoulder.
“Dusk,” said the prince, “mount me.”
“H-huh?”
The prince grinned coyly. “You can’t fuck your sister, because that’s against the rules, and your sister can’t fuck you. But, dear Dusk, there is nothing in the rules that states you can’t fuck a stallion as he fucks your sister. You’re going to fuck me as I fuck her. You will control the pacing, the power, the speed, and I will be a conduit for your love.”
Dusk swallowed, his tail twitching in anticipation. “Oh! I, uh, I can do that...”
With a thought, Bolero cast a spell to lubricate both Dusk’s cock and his own cock. He winked at his brother in law. “I know you can.”
Dusk Shine mounted him, both nervous and eager, his lithe body settling on Bolero’s back. The unicorn was no longer the scrawny teenager that first left for Ponyville years ago, but he wasn’t the peak of toned, aesthetic perfection that Bolero was, and he didn’t have the heavy, military build of his sister. Bolero recalled carrying Dusk on his back years ago, when he would take the young unicorn through all the science and history museums of Canterlot and let the exhausted colt nap on his back on the way home. He barely felt any heavier now than he had back then.
Bolero’s wife looked up at him, eyes wide with anticipation, and he felt Dusk’s breath on his neck. “I have an idea,” said the prince. He moved his head down and to the left, until he was nuzzling the side of Gleaming Shield’s neck. “Now, my loves, you can look each other in the eye.”
Dusk sucked in breath, looking down at his sister. “Are you guys r-ready?”
Gleaming Shield nodded her head with astounding speed. Bolero chuckled, and said “Go right ahead.”
Dusk Shine’s cock jabbed clumsily at Bolero’s backside, unused to mounting stallions in this way. The hot tip prodded his buttocks and the base of his tail, before settling on his hole. Bolero mimicked the unicorn’s movements, until his own tip came to rest on his wife’s ass.
Gleaming Shield’s breath hitched. “In my ass?” she whispered.
“Yes, your brother is fucking you in the ass.” Bolero grunted softly as Dusk pushed his hips forward.
Bolero exhaled as the flared head of Dusk’s dick slipped inside him. His wife was not so quiet as he copied the action. She moaned at the sensation, her hind legs wrapping tightly around her husband’s hips.
“Brother, you’re so big!”
“Oh sister, you’re so tight and hot!”
“Lead him on, sweetie,” whispered Bolero, “tell him how to move.”
Gleaming Shield giggled softly, looking up. “Deeper, little bro. Go slow...”
Dusk slid in deeper, eyes shut tight, muttering minced oaths and nonsense. Prince Bolero thrust in turn, feeling Gleaming’s toned stomach muscles ripple beneath him. She bit her lip at the feeling of fullness and opened her legs wider, sweat running down her cheeks and brow. Her front legs pawed at the sheets as Dusk thrust again, unintentionally flexing her powerful leg muscles.
“Woah.” Dusk swallowed as he gawked at the sight.
Gleaming smirked. “You like that, bro? You like seeing your sister’s muscles?”
“Uh-huh...”
“You like seeing me all freakin’ sweaty and shredded?”
“Uh-huh!” He grinned and thrust hard, Bolero doing the same as the dick filled him.
Gleaming squealed with delight. “Oh bro, you’re so freakin’ cute, your dick feels so good in my ass!”
“S-sis, you’re so hot, I’ve wanted this for so long...”
“Oh yeah? You’ve wanted to feel my ass squeezing down on your dick?” She clenched her ass muscles tight, so tight that Bolero groaned softly at the sensation of her buttocks massaging his member. He followed suit with his own ass, tightening around Dusk.
Dusk cried out. “Your ass feels so good, sis!”
“I love you so much, bro!”
“Sis, I wanna be like this forever!”
Gleaming cooed, touching her brother’s chin with a hoof. “Go wild, bro. Just pin me down and rail me.”
Dusk Shine growled softly as he followed her command. He was uneven at first, sinking right in, deep enough to make Bolero gasp. Gleaming Shield threw her head back and squealed as her husband did the same. It took a few minutes for Dusk to find his pace and get comfortable, his hips going from jerking and uncertain to fluid and purposeful.
Prince Bolero mimicked every action perfectly. He thrust when Dusk thrust, bit when he bit, every caress and kiss that Dusk put on him was carefully repeated on his wife. It took every ounce of concentration not to lose himself in the sensation, his ass stretched wide by a cute nerd as he screwed his beautiful wife.
“K-keep talking,” he said, his voice low and husky, “let each other know how much you both want each other.”
Gleaming Shield was almost crying. “B-brother,” she said, still touching his cheek, “touch my pussy. Use your magic.”
Dusk’s horn lit up, but he was unsure. “But...”
“It doesn’t count if it’s magic...” murmured Prince Bolero.
Instead of using telekinesis, Dusk cast a complex spell. Instantly, Gleaming Shield twitched and shouted.
“Brother! What the h-hay, ohhh that feels so good it’s--it’s like tongues and mouths and they’re all eating me out--” she trailed off into nonsense syllables, her eyes rolling back. Bolero felt every muscle in her thighs and groin quiver furiously.
He laughed. “I like that! You mind showing me that one later--OH.”
Dusk cast a second time before the prince could finish his sentence. Bolero immediately understood his wife’s reaction. He felt lips and tongues on his balls, four sets at least, all as warm and wet and eager as the real thing, lapping up the sweat, smooching them, suckling them gently.
“Sweet Canterhorn, Dusk! Where did you learn that?”
Dusk laughed weakly, not stopping his thrusts. “I invented it when I w-was at the School for Gifted Unicorns so I could masturbate less and study more. It, uh, it kinda backfired...”
Bolero shivered as each of his balls was sucked into a spectral mouth. “I can see why...”
The prince gave himself into the pleasure, more than a pony, more than even an alicorn, he was the love of three ponies made incarnate. He felt every bump, ridge and swell of Dusk’s cock while he felt the warmth, the grip, the tightness of Gleaming’s ass. With Dusk so deep inside him, the prostate stimulation didn’t just make him hard, it made him ache. It took all of his discipline not to cum right there, and even then he knew he could not last long. He knew the siblings were also close.
“I love you, L.B.B.F.F.!” cried Gleaming Shield.
“I love you, B.S.B.F.F.!” replied Dusk Shine.
“Kiss!” commanded Prince Bolero.
Dusk and Gleaming set on each other instantly, mashing their lips together, crying with joy as they climaxed simultaneously. Bolero closed his eyes and moaned as hot sperm filled his ass while his wife clenched around his cock. He could no longer contain himself, gritting his teeth as he came inside his wife. All of their thrusts became slow and spastic, thick cream flowing out around softening cocks. The three of them stayed there, deeply contented, resting against each other for some time.
Shortly after that, the panic started.
“Oh no,” said Dusk Shine.
“Oh no,” said Gleaming Shield.
“We kissed each other.”
“That’s incest.”
“That’s against the law!
“We broke the law!”
“Prince Solaris will find out...”
“I dragged my husband into my crime spree...”
“I’m going to be banished to a dungeon!”
“I’ve disgraced my commission!”
Prince Bolero sat upright and muffled the terrified unicorns with his wingtips. “Gleaming Shield, Dusk Shine, please! Before either of you say another word, can you tell me which part of the Equestrian Legal Code concerns incest?”
Once more, the two siblings avoided his eyes. Gleaming Shield cringed. “I think it’s the blue part?” she ventured.
Dusk Shine cleared his throat. “...Actually, I’ve never been brave enough to look at that particular section of the law.”
The prince sighed. “Equestrian law states that all forms of childhood incest are illegal, and forbids incestuous marriage. Otherwise, that’s it. It’s a free monarchy.”
Both unicorns gawked at him. He smirked back. “So, yes, your desires are only limited by what you choose to consent to. And since I love both of you dearly, and you both love me, and you both love each other, I am perfectly happy for you two to do whatever you desire to each other,” he said, his voice dripping honey. “Now, I am going to have a shower, and you two can discuss in detail exactly what this means for the pair of you.”
With that, he sashayed out of the room. Dusk Shine and Gleaming Shield looked at each other, sweating. The night had only just begun...
