Twilight Sparkle had always had a thing for her brother but was too afraid of what would ever happen if she told him. Who could blame her? Even though for most the idea of having sex with one’s sibling would be frowned upon just about anywhere, who couldn’t love the muscular stallion? He had always been there for the unicorn when she was lonely, he was sweet, full of enthusiasm and a loving brother. Then she came, Cadence. Secretly, she was always jealous of her. One time she spied her brother and her kissing, most siblings would be happy for something like this, not Twilight. She was so enraged she did the only thing she knew any sensible pony would do, revenge. She filled a bucket full of caramel above the door and laughed when her eyes happened upon the camel covered alicorn, she laughed that day for an hour on end to the mare’s misfortune. Other than being her love's rival, they were good friends. All her dreams had seemed to be crushed when she heard the word she hoped to never hear, marriage. Well this was what she first though as the week before the wedding, she never left her room and filled the sound of it with sobs until she came up with a devious plan, a delicious, awful plan. She would give her and her newlywed wife her body for her wedding gift. She approached their bedroom after the reception, nervous with what she would have to admit. Three raps were made on the door.
“Hello,” Shining Armor said quizzically, wiping his sleepy eyes,”oh it’s you, Twily! It’s so nice to see you. Anyways, I want to ask you why you haven’t given me my wedding gift?”
“Oh about that,” she said tugging her neck with one of her hooves.
She was cut off by Shining Armor,” you look nervous, is there anything you need to tell your B.B.B.F.F. ?”
She gave out a sigh and explained,” Shining, I’ve always had a thing for you and I wanted to make it up to you by having a threesome with Cadence.”
“Wow, Twily, I never knew you had feelings like that for me.”
“I’m sorry, you probably think I’m a freak and want me gone,” she interjected a tone of defeat in her voice.
“It’s kind of weird, but I want you to stay,” he assured they crying unicorn and wiped her tears as he hugged her,” don’t cry, I hate seeing my little sis so sad. You know I love you, mind you not in that way, but if Cadence doesn't object, I guess we could give it a try.”
“Really, you’d do that for me?”
“Of course, I guess, what are siblings for?”
“Thank you!”
“Don’t thank me yet, Cadence still needs to agree," he opened the door further to call her,”oh Cadence, Twilight was going to gift us in the form of a threesome, are you okay with that?”
“I’m a bit disturbed, but i’ll agree. And by the way I knew you were the one who poured caramel on me! That took a week to get completely out of my coat. Also, I always knew you were hot for your brother.”
“You make it sound even weirder than it is when you put it like that.”
The three walked to the bed, awkward expressions worn on all their blushing faces. Cadence had got into a position where she could kiss her lover but not in a way that she was directly on top of the stallion. It was hard for Shining to admit but when Twilight swished her tail to reveal her marehood, he felt a raging boner form. The Idea of rutting two mares at once was almost too much to bear, even if the other mare was his sister. Before Twilight could start licking his dick, he spoke,” Now this needs to be our little secret, all right,” he had parted the kiss to say this important piece of information.
“Ok, big brother, this will be our deep, dark secret. I wouldn’t want to explain my feelings anyway”
“Good, you can start now.”
She started to lick his member, eliciting a pleasurable moan of excitement. She then proceeded to lick at his medial ring, Shining had gave a shriek not unsimilar to when a fan pony meets a Wonderbolt in the flesh, this turned Twilight on and she started to suck with a faster pace than she had done licking, making her brother moan loudly while he was still kissing cadence. The two parted the kiss, silva still between their muzzles as they smiled at one another. Cadence had gone to the back of the pair and started to lick at her step daughter’s pussy which made Twilight moan. She parted her love tunnel and lapped at her wet vagina, savoring every bitter bit and enjoying her moans to her good administrations. She found her nub and bit at it, causing Twilight to squeal in a high pitch as her damping pussy started to clamp on her tongue, she was close. Finally she gave out a loud and long moan as she coated her step daughter’s muzzle in cum, bucking her hips as she did so. Shining had the same sensation as he fired load after hot load of the white sticky substance filled his sister, a little dropped out onto her coat, luckily she wasn’t in heat so she wouldn’t have a foal.
Twilight shifted on top of her brother, she kissed a hesitant brother who didn’t want to at first since it was weird that he was going to kiss his sister, although they already did a lot worse and for the fact he didn’t want to taste his own cum. He finally decided to give in, tongue wrestling with each other, filling his mouth with his sister’s silva and his own ejaculate. Cadence had given him a surprise as she gave him a rim job, he moaned when he felt her tongue meet his anus, she did this so he would be hard again, much to her satisfaction, it had worked. He moaned as her tongue poked deeper into his rectum. She kept going, deeper and deeper when he had let out a loud, pleasurable moan as she contacted his prostate. By the time this happened, he had hardened to full length.
Twilight had parted the kiss they shared, giving him a very seductive smile and wink. She got off of him and took his old position. Shining took Cadence’s place and she got in front of Twilight to kiss her. Shining guided his penis into her sister’s vagina and as he prodded it, it elicited a gasp and then a moan. He started in a slow rhythm pumping his shaft in and out of her as she kissed her step daughter, tongues locked in an intimate battle. After a while, Shining’s rhythm quickened making the two moan more rapidly. Their shrieks filled the room bringing them over the edge, Shining came inside his sister, filling her womb with the hot seed, some of it soaking the sheets. Luckily for the pair, his sister wasn’t in heat, meaning their wasn’t going to be a child.
Cadence broke the kiss to meet Shining to stroke his member back up again. She loved hearing him squeal like a school filly, making her giggle. Soon enough, it had grown back to it’s hardened state. He went behind Cadence and poked his member inside of her. He started slow again, he wanted to savor this. They started moaning loudly as Twilight moved in front and bit at his neck, causing him to squeal in an unmasculine tone. She then seized her biting to kiss him, muffling his grunts and moans. The humping grew more rapidly with their moans matching their pace. He finally came inside his lover, their juices mixing with some spilling them onto the bed.
Twilight lapped up her brother’s cum from his step daughter. She moaned as Twilight cleaned her tunnel out.
She broke away from the pussy to say seductively,” Oh, I like your cum a lot, Shiny.”
The two mare got into a scissoring position and started grinding away at each other, the two moaning. They started slow to prolong the pleasurable experience. Shining scooted away from them and started to moan as he stroked his member and in his other hoof bounced his balls to help the cum get out quicker. The two quickened their pace, which received more and louder moans. The two then started to kiss, tongues in a wrestling match, their hot breaths huffing into the other’s throat. After a while the two came, which drove Shining crazy, he unloaded himself onto the two mares’ faces. The two satisfactorily licked the oozy substance off to be met with the bitter, yet satisfying.
“Thank you,” Shining said, panting with the other two.
“No, thank you, I’ve always wanted to do this,” Twilight replied, saliva still connected to her mouth.
“Hey Twi,” asked Shining,” could we do this another time?”
“Sure,” she exclaimed.
The next night things were going to get kinky.
