Twilight tossed in her bed, attempting to hide from the image of her brother that was pursuing her thoughts with relentless ferocity. Even though he wasn’t with her now, she could still smell his scent on her fur. Even though her eyes were closed tight, she could still see his face etched onto the back of her eyelids. Even though the room lay in complete silence, his strong yet kind voice still rang inside of her head. Even though he wasn’t there to share his warmth, her body burned in fever, the heat between her thighs boiling away in the form of hot juices trickling down her hind legs.

Twilight threw herself to the other side of the bed and pulled the nightstand open. She took the replica of her brother’s cock and pushed it between her thighs to drive the heat away as she had done many nights before. It didn’t work now. The toy felt cold and crude and gross and Twilight loathed it with all her heart – a shallow copy of her brother’s body. She needed to see him. Real him. Just one glance at her brother would give her more to work with than a lifespan with the most accurate replica in the world. She threw the dildo back into the nightstand. Just one glance. Twilight assured herself. Nothing more. One glance would be enough to clop myself to sleep.

Casting her bed covers away, Twilight jumped onto the floor and hurried away to the hall. The darkness enveloped her the moment she left her room, keeping hold of her and making her heart race as she crept along the crystal corridor toward the chamber where Shining and Cadance stayed for the night. She didn’t dare light her horn to illuminate her path and instead felt the walls along the way with her hooves. It made her feel like a thief who had broken into another pony’s house to steal from them. The fact that it was her own home, along with the familiarity of its turns and twists didn’t do much to convince her otherwise.

Finally, the darkness gave way and Twilight saw a blue light shimmering around the entrance to the corridor that led to her brother’s bedroom. Twilight trudged along the blue aura with difficulty as if slogging through a swamp until she finally reached the end of the corridor and was mere steps away from her destination. She recognized the spell and remembered that she had been using a similar one to keep ponies away from her room while clopping. Unlike her version that blocked everything and everypony, Cadance’s spell was more intricate, scanning a pony’s body while they tried to walk through it and stopping them if they failed authorization. Cadance hadn’t been joking and had done everything possible to keep Twilight’s visit a secret. Twilight frowned at the thought, wondering whether Cadance was ready to go through all this trouble for a slim chance of her turning up here, or was her former foalsitter so confident in her prediction as to be sure that Twilight accepted her offer. In that case, Cadance was wrong. Twilight’s desires might have brought her to her brother’s door but that was it. She would never in her life cross it.

The door stood before Twilight, ajar with a slim beam of light emanating from the crack like a path to heaven, amplified ten folds by the darkness surrounding her. An indistinct chatter flowed from the room, beckoning Twilight to take a step closer. Her legs trembling, Twilight inclined forward and placed her eye against the crack.

Twilight gasped as her eyes adjusted to the bright light and the whole picture of what was going on in the room unrolled before her. Her brother was mounting Cadance, thrusting his hips back and forth with a relentless force. His hooves were wrapped around her back and barrel as his teeth nipped at her nape aggressively. The noise Twilight had taken for a chatter were ecstatic moans mixed with a wet sound of flesh slapping against flesh. Twilight’s legs gave up and she slid down onto the floor. She stuffed a hoof between her damp thighs.

Every idea on how sex might work that Twilight had derived from books and magazines withered away as she watched the carnal passion unfolding before her. Nothing could have prepared her to this. Twilight stared at her brother fucking his wife, mesmerized, her hoof rubbing her pussy relentlessly. Never in her life had Twilight’s attention been focused on a subject so unreservedly, not even during the most important of Celestia’s lessons. Despite the impossible speed of their fucking, Twilight was able to make out her brother’s cock sliding from the opening of Cadance’s pussy, the underside of his shaft brushing her feverishly winking clit. He pulled away briefly until only the head of his cock remained squeezed tightly by his wife’s dripping snatch only for his cock to be slammed back into the depths of her tunnel, making Cadance squeal with desire for more.

Oh, how she wished to be in Cadance’s place. Be the one who was begging for her brother’s cock to be rammed into her. Twilight pressed a hoof against her pussy harder and flicked her clit up. It didn’t take long before she began to do what she had mastered to perfection over all those years – imagine her being in her brother’s wife’s place.

“So, how was your day out with Twilight?” Cadance managed through a moan. On the other side of the door, Twilight was being too occupied trying to conceal her own moans as to pay the budding discussion any real attention.

“It wasn’t that bad,” Shining hissed through gritted teeth as he pushed into Cadance, a wet squelching sound almost swallowing his words. “But I think she’s still somewhat angry at me. Though I don’t understand what I’ve done wrong.” Another powerful thrust driving Cadance’s face into the cushion.

“Give her time.” Cadance bit her lip but a moan nonetheless escaped her. “I’m sure she’s thinking about how to mend up your relationships right now.”

“I hope she does. I’ve run out of ideas on how to approach her. I wish she just told me what’s gnawing at her heart.” A dull sound ran through the room as Shining’s hoof slapped Cadance’s flank unceremoniously.

“And what about that Starlight pony?” Cadance muttered, her head buried in the pillow. “I saw you two drinking a cocktail together. Did you like her?”

“Why would I? She has nothing to offer me that you don’t have, honey.”

“Sure.” Cadance moaned into the pillow as her winking clit brushed against the flat tip of Shining’s cock. “And now the truth, dear.”

“Well, it was very cute watching her try to seduce me. She was very cute.”

“But you didn’t give her any attention, right?” Cadance’s horn glowed and she fumbled her husband’s balls with her magic.

“Of course not. You’re the only mare who holds all my attention, honey.” Shining thrust his hips into Cadance’s spasming pussy with a ferocity to emphasize his point.

“Good.” Cadance’s clit winked once again and more of her juices began to trickle down her thighs.

“Cadance... I think I’m about to cum.” Shining’s breath became rapid as the rhythm of his pumping increased.

“Just make sure to pull out. I am in season.”

“Are you sure you don’t want another foal?” A hint of sadness spoiled Shining’s blissful expression.

“Don’t even start on that. It took me a whole day to find a pony oblivious enough as to agree to foalsit Flurry Heart while we’re away here.” Cadance bit her lip and moaned in delight before continuing. “I don’t have another twenty-four hours in my day for another foal.”

Shining didn’t answer and instead drove himself into his wife to the hilt with a guttural groan, then drew back and pulled his cock out of his wife completely. The head of his cock flared and a gush of thick cum burst out from it, landing on Cadance’s back, flanks, and tail, painting her body in snow-white.

After a moment of post-orgasm panting, Shining wiped the sweat off his forehead and said, “I wouldn’t mind having another foal though. A colt. Playing hoofball with him. Watching wrestling together. Perhaps one day he would follow family tradition and join the military. Like me and my father and his father.”

Cadance climbed off the bed and kissed Shining on the lips. “Maybe when Flurry’s grown up I might think about it.”

Shining looked at his wife gloomily, sighing.

“Don’t be sad, dear,” Cadance said, a smile forming on her face. “I know how to lighten your mood up. Because you were a good boy today, I have a present for you. But it’s a surprise.”

Cadance drew out a blindfold and waved it before her husband. She propped Shining upright against the bed’s headboard and put the blindfold on him.

“Cadance, you know I don’t like surprises that much,” Shining complained.

Cadance rolled her eyes. “Fine, I can tell you, I guess. I was talking to Starlight and she confessed to me that she finds you very attractive. So I decided that it wouldn’t hurt if she joined us today for a little bit of fun.”

“Wow, really?” Shining reached out to take off his blindfold but Cadance stopped him.

“Really. But you are to keep this. As you might have noticed, Starlight is a very shy pony when it comes to the opposite sex and she has never lain with a stallion before. She is very, very self-conscious about herself. It was her wish to have you wear a blindfold.”

“Well, it’s kinkier than usual but I hardly can say no to a good threesome, can I? Is she waiting behind the door? I’m sure I heard a wet sloppy noise coming from there. I guess she started the fun even before hitting the bed.” A laugh escaped Shining.

It was only when Cadance opened the door with her magic did Twilight’s mind catch up with the conversation that had just happened. She began to spin her head around rapidly, expecting the condemning eyes of Starlight staring down on her sprawled form but there was nopony behind her but the thick darkness.

Twilight jumped back in shock as a hoof grabbed her foreleg. She turned around and sighed with relief. It was just Cadance. The Princess of Love had already known everything about her. Of course, she would never invite both her and Starlight at the same time after having sworn it to be a secret between them.

Cadance helped Twilight to her hooves, trying her best to ignore a viscous puddle of Twilight’s juices spreading across the floor that she had accidentally stepped on. She tugged Twilight to get her inside but Twilight pulled back hard. “Are you going to come in, Starlight?” Cadance asked.

Twilight wanted to say ‘No, I’m not’ but shoved a hoof into her mouth just in time to prevent herself from spilling the words out and allowing her brother to recognize her by her voice. Even while horny as hell, hornier than she’d ever been in her entire life, the fear helped the gears in her head keep going. Was she really going to sacrifice everything she had and loved for a mere night of carnal pleasure? No, she wasn’t. She was Twilight Sparkle. The representative of magic. Celestia’s personal student and a Princess of Equestria. Not a wanton slut from the slums who could not control herself. She shuffled her hooves around and started to her room, her eyes seeing off Shining’s sitting form. She’d promised herself just one peak and had more than enough of them for the rest of her life.

“Is something wrong, Starlight?” Shining asked, stretching on the bed. “Don’t be afraid of me after you’ve already come all the way here. I won’t bite.” He laughed. “If you don’t want me to.”

Terror seized Twilight as the realization dawned upon her. If she did nothing and just ran away her brother would go after Starlight, real Starlight, and ask what had gone wrong. Starlight would say she had no idea what he was talking about and take it as an affront to her honor. And this would be the least of Twilight’s worries. Then her brother would deduce that it should be another pony who’d been there and the only pony he would be able to choose from would be her! Twilight Sparkle. His own sister, stalking his bedroom at night to watch him have sex with his wife. He would think of her as a crazy freak and never talk to her again. Twilight’s teeth chattered. The only way out of this situation was to continue to play Starlight. Hesitantly, Twilight turned around and allowed Cadance to lead her into the room.

Twilight was making every step with tentative care as if afraid that her brother could recognize her by the sound of her hoofsteps and be scared away. She approached him like the most precious treasure in the world. And what the gems that treasure held! Twilight’s eyes were fixed on her brother’s massive balls, taking in every little spot and crease. Even his cock, though spent, was a scene to behold, lying on her brother’s belly, twitching slightly, eager to be raised to its glory once again. Twilight’s pussy spasmed, forcing her clit to peek from her labia, declaring to the world how hungry she was for her brother’s thick cock. As if a hungry look in her eyes wasn’t enough.

“His face is a little bit higher,” Cadance said, smiling. “Why not get to know each other better before jumping on him?”

Twilight’s cheeks flushed with crimson. Even though her subconscious tried to avoid any eye contact with Shining, it was time to let those fears go after she had gone so far. If she was going to have sex with him, it would be with her brother, not a faceless piece of meat looking like him.

Taking a deep sigh, she let her eyes travel along her brother’s body, up his belly, his chest, all the way up until she met... Twilight almost forgot that her brother’s eyes were hidden under the blindfold. Of course, they were. And what they were seeing through it was another mare, not his own perverted sister. A sudden impulse made Twilight want to rip off that piece of fabric that separated them. She made a mental attempt to move her hoof but her body didn’t listen to her. An image of what those eyes would reveal to her after she had pulled off that blindfold paralyzed her every muscle. His smile is enough. It is more than I have ever had.

Twilight sat down on the edge of the bed, her every limb trembling. It took help from Cadance to have Twilight straddle Shining’s lap. She gasped as her sensitive lips brushed against the medial ring of her brother’s cock that was now squeezed between her tits and his abdomen. She pressed her hind legs around her brother’s sides tightly and couldn’t help but fidget as her brother’s cock continued to stiffen under her, now rubbing against her winking clit. She didn’t have the strength to keep her back straight and fell down on her brother’s chest, their faces mere inches away from each other, their hot breaths intertwining.

“Well, what are you waiting for? Kiss him,” Cadance said from nearby, her tone reminding Twilight of the instructions Celestia would issue when she needed her students’ special attention.

Taking a deep breath, Twilight nodded to herself. That was it. Her first real kiss. With a real pony. No, she amended herself. With her brother. And this time she wasn’t going to flinch away. Her heart pounding in her chest like a drum, Twilight puckered her lips and forced her head forward, surmounting the last inch that separated her and her brother. As their lips met, a jolt of realization hit her chest. She didn’t know how to kiss! She desperately tried to remember everything, something she’d read about the matter in the books but nothing coherent came out of this. She moved her lips awkwardly like a fish suddenly plucked from the water, her eyes wide with panic. That was when her brother’s strong tongue pushed its way through her teeth and she closed her eyes tight as Shining began to caress and explore her mouth. His lips pushed against hers like a silky soft brush, his teeth grazing against her gently.

When Twilight thought that the moment of their union couldn’t feel even better, her brother grabbed her asscheeks tightly and began to massage them in circles while still caressing the insides of Twilight’s mouth. Twilight melted away in her brother’s embrace completely and gave up any initiative she had, letting him explore her body in fullness. His hips moved back and forth, rubbing his cock between her tits and brushing the bottom of her vulva, soaking his length in her juices. He dared slide his right hoof deeper between Twilight’s asscheeks and, after she didn’t give any sign of objection, he fondled her puffy butthole with the tip of his hoof.

Shining’s other hoof began its slow journey up Twilight’s slim body, exploring her feminine curves, sliding up her supple ass to her lower back, almost touching her wings... Twilight’s eyes opened wide with shock and she would have jumped from her brother to another side of the room if not for another hoof that stopped Shining’s advance.

“I think it’s enough for now,” Cadance said. “Don’t want our guest to hyperventilate here. Look at her, I think she forgot how to breathe.”

It was true. Now that Cadance had mentioned it, Twilight lifted her lips from Shining’s and began to rapidly pump the air back in her body, shaking with both fear and excitement after everything that had just happened.

It took Twilight some time to realize that something in Shining’s expression was off, his forehead creasing in confusion. Cadance had noticed it too.

“Is something wrong, dear?” The Princess of Love asked.

“No, nothing,” Shining said, his confused voice at odds with a composed demeanor he tried to put on. “It’s just... It’s just that she smells like... Twilight.”

Twilight heart skipped a beat and she hurried to cover her face with her hooves as if expecting the whole world crumbling down upon her.

“Of course she does,” Cadance said calmly. “You see, Starlight really suffers because of her past and is in need of a worth pony to look up to. Like Twilight. She’s trying to simulate her in every detail and of course it’s no wonder she would go as far as to use a perfume to imitate Twilight’s scent. In fact, her biggest request when we were talking about the night was to have you call her Twilight while fucking her.”

Twilight and Shining’s mouths fell agape in unison.

“What?” Shining sounded outraged. “You can’t be serious.”

“Is something wrong with that, dear?” Cadance’s grin broadened. “You were already thinking about your sister while kissing our guest here. Nothing really changes. Your head was already full of your sister’s scent. The memories of you and her at the time of your foalhood were bubbling up at the back of your mind and you imagined your sister was the one whose ass you fondled with your hooves.”

“I didn’t!” Shining protested. “It’s just... It was all too fast. Perhaps a thought crossed my mind once but it was just in the heat of a moment. I would never touch my little Twily that way in real life.”

Twilight’s heart sank at her brother’s words. Though what had she even hoped for? There was nothing new in those words, really. She had already known everything about her brother’s feelings to her for her entire life.

“Oh, don’t make me punish you, dear.” Cadance shook her head, her eyes narrowing. “You know very well I can’t stand lies in my bed. If you want, we will put an end to this little game in an instant. But first, I need to hear your sincere answer to my question. Don’t try lying. You know I read you like an open book when you try to hide something from me in bed.”

“Fine,” Shining said, puffing the air out of his mouth, the right corner of his lip curling up, indicating his irritation. “Whatever.”

“So my question is,” Cadance became slowly. “Have you ever in your life thought of the delicious curves of your sister’s purple plump ass? All the while imagining how good your cock would fit inside her warm welcoming embrace after you have mounted her. How loud she would cry your name, begging for you to thrust your cock deeper and deeper into her, proving your sister how much you really love her.”

Twilight felt Shining’s cock stiffen under her, his shaft throbbing, rubbing against the opening to her pussy with a renewed force. She herself also could tell that her clit quickened its winking, begging for the cock Cadance had just mentioned.

Shining’s cheeks glowed with red as he opened his mouth to speak. Then closed it. Then opened and closed again. Until at last, he gathered enough courage to speak his mind.

“Maybe it’s been a few times. Well, maybe more than a few times...” He let out a defeated sigh. “Fine, you won. I will be playing your game. But don’t either of you think that I really want to fuck my little sister. And it will be better if we all forgive everything about this night after it’s finished. My little Twily is too naive and pure to even imagine the scope of this depravity. She is to know nothing about it. That’s my condition.”

“Of course, nopony but us three here will ever know about this night,” Cadance said, both grinning like a mad genius and seeming to be offended at the same time. “Keeping things private was the first thing I taught our guest here. She of all ponies has the fewest reasons to blurt anything out.”

Cadance tousled Twilight’s mane playfully like she had done many times when she’d been foalsitting her and favored Twilight with a warm smile. Twilight smiled back, glowing with happiness. Her brother had been thinking of her! Not just as a sister but a mare. A mare he was thinking to have sex with. Even if it had been just a handful of times at the back of his mind.

Twilight couldn’t remember when she felt so happy in her life. Even when graduating from Celestia’s school for gifted unicorns she had been feeling a bit sad because of the separation with her mentor. But this? What Twilight felt right now was the definition of the word ‘happiness’ according to any dictionary. Every fiber in her body was filling with boundless energy. The night itself seemed to fade away and let light be shed on her head, every her doubt gone. She knew what she had to do. Never in her life had she been so sure in her decision as she was right now. She was going to make him regret. Make him curse himself for every chance to fuck her he had missed. She was going to make him be the one begging for her.

Twilight jumped off her brother’s lap and slid back until her rump lay inches away from the edge of the bed and her muzzle inches away from her brother’s throbbing erection. She took Shining’s cock in her hooves and rubbed it against her cheek tenderly. The sensation of having her brother’s stallionhood brushing against her face was even better than she had dreamed of. Even the replica she had painstakingly crafted paled in comparison. Though something felt a little bit off as she continued to probe Shining’s cock. The medial ring was half an inch higher than she was used to knowing! Had she messed up the proportions of the replica or had Shining grown up since her last measurements? Twilight horn glowed and a purple aura enveloped the entirety of her brother’s length, exploring every inch of it. He had grown up. Twilight made a mental note to update her equations and prepared for deep research of her brother’s body.

She stuck her tongue out and probed Shining’s pee hole, gently swirling her tongue around the tip. A sour-sweet tang of Cadance’s juices washed over her taste buds, rivaling with her brother’s more pungent musk. She found herself liking the mix. Cadance’s aroma was somewhat softer and sweeter than her own lavender flavor and she imagined her brother’s cock slathered in a thick candy syrup while giving him a long lick over the glans.

Shining’s cock made a throb, letting out a droplet of cum left from his previous orgasm. Twilight lapped up Shining’s gift eagerly, savoring her brother’s real taste for the first time in her life. He tasted just as good as she had imagined, his viral odor making her crave for more. She clenched her hind legs subconsciously, her clit winking, as she finally sent her brother’s nectar down her throat.

She enveloped her brother’s cock with her hooves and began to stroke the length as her tongue explored more and more of Shining’s wide flare. Her ears lifted up excitedly as she heard a first moan escape her brother’s lips. Her brother was feeling good because of her! Twilight could barely hold back the thrill rising up inside her and pushed her muzzle into her brother’s scrotum to muffle the squeak of excitement. She rubbed herself against each of her brother’s plump balls happily, took a deep breath of his scent and began to slowly trail her tongue all the way upwards, slobbering excessively and adding her saliva to the mix of her and Cadance’s juices. Slick as her brother’s cock already was, Twilight’s countless lessons had taught her that it was crucial to make the cock as slippery as possible for what she was about to perform.

“You are very good at sucking your brother’s cock, Twilight,” Cadance said, her hoof sliding down between her hind legs, emphasizing her point. “Very good.” The Princess of Love’s face contorted with pleasure as she began to rub her pussy.

A smirk spread across Twilight’s face as she eased her brother’s cock into her mouth and began to suck on it tenderly, her tongue swirling around the circumference of his glans. Oh, I’m just getting started.

How many times had she imagined this situation before her, producing it in her mind with the help of the dildo she had specifically made to practice with? Twilight had lost count long ago. All of those long nights, the exhaustive training of her throat she had almost given up once. It seemed like her whole life converged to this very moment. It was her chance to show her brother that she was ready to do anything for him. Show him that her love to him was infinite, having neither a limit nor a base.

Twilight closed her eyes and relaxed every muscle she had, getting into the meditation she had taught herself while practicing on the replica of Shining’s cock. The inner working of her body slowed and her breaths became spare, just enough to support the vital organs while putting the rest to dormancy.

Twilight put her hooves down on the bed by either side of Shining’s hips, holding her brother’s cock by the tip with only her mouth. She pushed her head slightly down, massaging the entrance to her throat with the cock’s glans and pressing it further but not quite gulping the tip down yet. A few more bobs over her brother’s cock and with a big final breath, she plunged in.

Neither Cadance nor Shining was prepared for what happened next. The tip of Shining’s cock plopped into Twilight’s throat without delay and the force with which Twilight threw herself on him carried her all the way down until her muzzle landed on the fluff of Shining’s groin. Twilight made a gurgling sound as she tried to make herself comfortable between her brothers’ hind legs. A stream of saliva was leaking from her outstretched mouth, dripping off on her brother’s balls. Twilight’s neck bulged outward just enough for her brother’s cock to be completely enveloped in the velvet warmness of her tight throat. He fit her perfectly and she basked in the sensation of having every corner of her throat filled and stretched with her brother’s thick cock. They were now connected not just by blood and memories, but as entirely as two ponies loving each other possibly could.

“Starlight...” Shining uttered through gritted teeth, his hooves wrapped in the bed sheets, clenching them in two tight knots. “Fuck it. Twily, you are incredible.”

Twilight smiled around her brother’s cock. She knew he would love it. And it was only the beginning.

It took Shining a while to come back to his senses after an incredible wave of sensations that had surged through him in a mere moment. His breathing returned to a steady rhythm and he finally let go of the bed sheets to fumble around his groin with his hooves. Obviously not finding his cock, he brushed Twilight’s inflated cheeks. He continued to trail his hooves up her head as if unable to believe that somepony could swallow down a cock so expertly. He touched her horn and petted her head. It wasn’t some trick. It was a real pony. And she was still there. Her lips were brushing his balls while his cock was buried deep inside her throat.

“Honey, are you sure she’s never had a stallion before?” Each of Shining’s words left his mouth as a moan, his hoof continuing to pet Twilight’s head affectionately.

“I’m quite sure, dear,” Cadance said, her eyes wide, a hoof between her hind legs now rubbing against her wet slit with incredible speed. “It seems she’s been training a lot.”

Despite the enormous girth of her brother’s cock, Twilight’s cocky smile grew even so. She decided that it was the perfect time to show off her real talents.

She lifted her head off Shining’s cock until only the tip remained tucked snugly around the entrance to her throat. She then dived back in, gobbling up her brother’s entire length in one go, her throat stretching and tightening at once to massage him. A gurgling sound escaped her lips as she reached his groin, more wet squelches following as she raised her head, releasing most of her brother’s cock only to dive in again a moment later. She found a steady rhythm of fucking her brother’s cock with her throat and just enjoyed the feeling of his great girth inside of her, filling and stretching her. Trickles of drool flowed from her mouth as his virile scent overwhelmed her senses.

Shining’s hooves wrapped around Twilight’s head firmly as he tried to follow the rapid bobbing of her head. “Twily, I’m cumming!” A guttural sound escaped him. “Drink it all down.”

Twilight’d never heard her brother sound so savagely like this before. With some force, he shoved her head along his cock all the way back down to his crotch, holding her in place there. Shining’s cock gave out the last powerful twitch inside of her and his tip flared, extending Twilight’s neck outward to its limit. A gush of thick hot cum rushed into her stomach.

Twilight had been ready for this moment almost her entire life and let her throat milk her brother’s cock completely, gulping his gift down her gullet. What she wasn’t ready for was the sheer intensity of her brother’s orgasm. Twilight began to doubt her ability to handle her brother properly after the fourth jet of cum hit the back of her overflowed throat with the same ferocity as the first three squirts, if not even stronger. The fifth and sixth sprays of his thick cum splashing inside her only confirmed her fear. She couldn’t keep up with the enormous amount of passion her brother was offering her. Her throat and nasal canal were stuffed to the brim quickly and though she tried to slurp everything down, more and more of her brother’s cum was leaking out of her nose and the corners of her mouth, mixing with her saliva and bubbling down her chin.

At one point there was so much cum flooding her that for a moment Twilight thought she might drown in it. The last of the oxygen in her lungs was gone and Twilight’s primal instincts kicked in, crying at her to take out the foreign object from her throat right now. She lit her horn purple to cast herself away from her brother’s tight grip on her head but he let go of her just in time and Twilight lifted herself up, expelling all her brother’s length from her mouth in one pull. Shining’s cock sprang up and the last gush of his thick cum drew an arc in the air before landing on Twilight’s cheeks, horn, and splashing down her mane.

Twilight gulped in a lungful of air through her burning lungs and began to wheeze, coughing her brother’s cum out of her overstuffed nose and throat, milky tears running down her cheeks.

“Fuck. That was the best head in my entire life,” Shining announced blissfully, his head thrown back in ecstasy. He stretched his limbs and smiled. “I love you so much, sis.”

Twilight reached up with a hoof and wiped away a tear, this time the one of happiness. “I love you too, BBBFF.” She shut her mouth with both hooves, wincing, but it was too late.

The longest moment in Twilight’s life followed. Both she and Shining armor sat entirely still, forgetting to breathe.

“I guess, there’s no point in games anymore.” Cadance pulled a soaked hoof from between her hind legs and stretched it out to her husband’s face, lifting up his blindfold.

Shining’s eyes went wide in shock the moment they got their freedom. “Twilight? Is it really you?” It was definitely her. It was his little sister. With his cum dripping off her nose and chin.

“I’m sorry. I’m so sorry.” Twilight closed her eyes and threw herself at her brother’s chest, wrapping her hooves around him tightly. “Please don’t hate me. Please don’t hate me.” She began to mutter, her stuffed with cum nose making it ever more incoherent.

If it was the last moment with her brother she would ever have, she wanted to prolong it as much as possible, feel the warmth of his body against her, remember his heartbeat, his scent. Twilight squeezed her forelegs around Shining with a renewed force, awaiting a push that would drive her away but instead she felt her brother’s hooves settle tenderly on her back.

“Don’t be silly, Twilight. I will never hate you.” He hugged her back, more tightly than he had ever before. “I love you. I will always love you.”

“So cute,” Cadance said. She put her hooves together before her chest and clapped them lovingly. “Twilight, I told you that you had nothing to worry about.”

A snarl showed on Shining’s face as he turned to face his wife. “Cadance, this time your games have gone too far. If you were thinking that after bringing Twilight here I’ll let it go, then you don’t know me at all.”

Cadance opened her mouth to speak but Twilight broke in with a cry. “Cadance has nothing to do with this! I came here by myself. You were always more to me than just a brother. I’ve been fantasizing about you and me having sex since I discovered what masturbation was. You are the only pony that kindles fire in my heart and loins. You are my special pony I can’t stop thinking about. You are my world and there’s no place for me to live without you.”

Cadance had been right. It felt good letting out all that weight that had for so long tore her heart apart. No matter what her brother’s answer would be, it felt good.

“I didn’t know...” Shining muttered. “I’m sorry that I’ve never noticed your feelings. I was a really bad brother, wasn’t I? But I’m going to make up for it. I promise you.” Shining placed a hoof under her sister’s chin. He lifted her head up and looked her in the eyes. “Will you have sex with me, Twily?”

“Do you really mean it?” Twilight could barely keep herself from exploding into tears. She had been dreaming about those simple words for so many years. Everything around her felt surreal and it was only because of her brother’s warmth that encircled her, that she could tell this time it wasn’t a dream.

Instead of answering, Shining Armor grabbed Twilight’s ass with his hooves and with a little help of his magic moved her backward and upward until her dripping pussy was lined up with the tip of his throbbing erection.

Twilight let out a whimper of pleasure as her lower lips parted to swallow her brother’s cock down her spasming tunnel, the sensation somewhat familiar and yet thousands times brighter than the piece of silicone she had been forced to substitute her brother’s cock with for so long. Familiar with Shining’s contour, Twilight’s pussy tightened around her brother’s cock perfectly, feeling his every vein as the shaft slid deeper inside of her.

“Congratulations, Twilight!” Cadance said beside the pair, watching the place of their connection closely. “You’re officially not a virgin anymore.”

Shining body's stiffened as he heard her wife’s voice, having seemingly forgotten that she was there. “Honey, I hope you’re not—”

“Relax,” Cadance said, poking her husband’s nose playfully. “I don’t envy. Almost. You can fuck Twilight as much as you want. Though it doesn’t mean I allow you to neglect me.”

Cadance lifted her flanks off the bed and, leaving a trail of her juices dripping on the bed, turned around to place her pink plump ass on her husband’s face. She made Shining lie on his back and aimed her sopping slit right down under his eager tongue, fixing his head in place with her hind legs and leaning against his chest with her forelegs for a better balance. “You better have your tongue ready, dear,” She said and pushed her asscheeks down, completely muffling any objections he could have had.

“Cadance, your Cutie Mark. It glows!” Twilight managed through a moan, her lips curling in bewilderment. Below her, her brother thrust his hips hard into her, spreading her pussy with his generous girth while licking his wife’s lips and clit hungrily.

Cadance looked down the crystal heart etched onto her flanks that were now gleaming brightly. “Ah. That?” She let out a moan as Shining forced his tongue into her slit and began to explore it thoroughly, a rivulet of Cadance’s juices trickling down his chin. “They always do this when I bring together two ponies who love each other. Though it’s the first time one of those ponies happens to be my husband and another one his little sister.” A grin showed on her face.

Twilight inclined forward and hugged Cadance with gratitude. She would never forget what Cadance had done for her. “Thank you,” she whispered.

“Don’t bother yourself with that.” Cadance returned the hug, wrapping her hooves around Twilight tenderly. “Shining has already always loved you. All I’ve done is give a little prod.” Cadance smiled, winking.

Twilight smiled back. With Shining’s hooves sunk into the flesh of her ass, she lifted herself from him slightly and then fell back onto his groin, feeling the entirety of him inside her once again and finding a perfect rhythm to riding her brother’s cock.

Meanwhile, Cadance’s face contorted in orgasm as her pussy contracted around Shining’s tongue, and all the pressure that had for so long been compressed inside of her flowed out, her viscous juices flooding her husband’s mouth. Shining hurried to gulp everything down while still remembering to suck on Cadance’s winking clit tenderly.

After Cadance’s orgasmic twitches subsided, she climbed off Shining’s face on her still trembling legs and patted her husband’s head. “Good boy,” she cooed. “Now be a good brother and make your sister cum as much as you have me.”

Cadance lay down on her belly and slid closer to the place where Twilight and Shining were connected. She stuck out her tongue and whipped the base of Shining’s cock with it, swirling around Twilight’s clit every time she descended on her brother’s groin. With a squelch sound, a spurt of Twilight’s juices escaped through the tiny gaps between her pussy and her brother’s cock and landed on Cadance’s waiting tongue. The Princess of Love licked her lips lustfully, swallowed down and continued to stroke the base of Shining’s cock with her tongue.

It proved too much for Shining and he squeezed his eyes, groaning. “I’m cumming, Twily. Get up off me or you might get pregnant.” He managed through a moan.

Twilight moved her hips even faster, slamming herself against her brother and kissing his groin with her pussy lips affectionately. She could feel the heat inside her was about to burst. “I know I might and I want it. I want your foal inside of me,” she muttered with her head full of pleasure, her pussy contracting around her brother’s cock greedily. “Please, Shining, you’ll make me the happiest mare in the world—”

Twilight broke off with a gasp as an orgasm hit her. She squeezed her brother’s cock with all the force she had, intending to milk his precious cum inside her.

“Fuck! I love you so much, Twily.” Shining groaned animalistically and thrust his hips upward into his sister’s depths with all the force he had, hitting her cervix and plugging it, making sure that none of his cum could escape from her. His flare widened and a gush of his hot cum rushed into Twilight’s womb, filling it to the brim.

The siblings panted in unison, their eyes fixed on one another. Neither of them wanted to break their deep bond. Alas, nothing lasts forever and Shining’s spent cock began to deflate and slide out of her. Twilight let out a little whine as she felt the emptiness inside of her return once more. Though this time everything was different. Even after her brother’s cock plopped out of her completely, she could still feel his warmth deep inside her, his seed rushing to her ovaries to fertilize her. At that moment Twilight knew that she would never ever have to feel lonely again.

“Thank you, Shiny,” Twilight whispered, rubbing her belly tenderly. “I promise I’ll raise the foal so that you will be proud of him.”

“Him?” Shining asked, puzzled.

“Somehow I know it’ll be a colt.”

A ringing sound ran through the room, turning Twilight’s attention to the clock on the wall. It was already midnight. Her birthday had just passed. When Celestia had asked her to throw a birthday gala, Twilight had known that many things could have happened during that day. But she could never have imagined that her life might have changed so drastically in one day. However, it was time to return to her routine. After a good night of sleep, the world, as she knew it, would still continue to drag along its mundane path, regarding the fundamental changes of her life as nothing but another grain of sand in the unending desert. Everypony expected her to behave as if nothing had happened. Pinkie Pie was still waiting for her to throw a real birthday party in her circle of friends. And she still definitely had her responsibilities as The Princess of Friendship. Cadance had provided her with enough material to work with for months ahead.

Twilight made to get off the bed but her right hoof got caught in Shining’s grip and her left hoof in Cadance’s. “Stay,” they said together.

Twilight stayed. The lights were shut off and the three ponies fell asleep, cuddling up against each other.

Tomorrow’s world might wait. Right now she was with her brother and her best friend, and that were the only things that mattered.
