"Remember Twiley, you can't tell our parents what we do at night. If you do, they will take me away, that's not what you want, is it?” Shining Armor said.

"B-B-But big bro, I don't like it. It hurts when you hug me from behind..." The young filly said.

"Shh.... I know it hurts at first, but you know that I'd never intentionally hurt you, right? You know I love you more than Equestria itself, don't you?" Shining tried to reassure her.

"Y-Yes big brother, I love you too. But why do you do it? What if we get caught?" Twilight asked.

"What we do isn't wrong, but other ponies don't understand our relationship. They think its wrong for a brother to love his little sister as much as i do. I'm still your BBBFF aren't I?"

"Of course you are big brother! Don't ever leave me! I won't let them take you away!" She cheered.

"Thanks Twiley, I do it because i love you, and it's something special that only ponies that love each other very much can do to show how much they love each other. How about i read you a bedtime story?" Shining asked.

"A story? Yay! Thanks big brother!" Twiley hopped up and down in excitement.

"I hope you like it... its a love story about a colt and filly that loved each other very much, and even though the whole town thought they should be apart, they stayed together and overcame the obstacles by keeping their relationship a secret." Shining explained.

"Oh, did - did they live happily ever after?" Twilight asked.

"Of course Twiley, but only after they were able to get away from the town full of hateful ponies that didn't understand their love. they moved far away and lived happily ever after together." Shining Armor assured his sister.

"That's a good story big brother! Let's um, let's pretend we escape too! Oh, but you're too old to play pretend..." She started.

"You may be right... But, you're not, and I would do anything for my favorite sister." He smiled at the young filly.

"Okay! Twilight climbs onto her brothers back “Let's go far away, where those mean ponies will never find us! Just, um, don't leave the house cause mommy says we can't be out after dark." She said with enthusiasm.

"Where would you like to go, Twilight?" He asked his sister.

"Let's go somewhere secret... the closet! No one will find us in there!" She near-shouted.

"That sounds perfect, Twiley. You are so smart." Shinging slowly walks to the closet, opening it slowly, peaking in as if expecting to see a beast come jumping out. He walks inside, and closes the door, and the lowers fore-legs to allow Twilight to dismount. "I think we are safe from the ponies that don't want us to love each other now." He finished.

"Big brother... I wanted to ask you something...I saw you talking to princess Cadance the other day, and she's really pretty. Do you, um, like her more than me?" The filly asked her big brother.

"Oh, Twiley... I like Cadance, but I there is not a single filly in all of Equestria i care for more than you." Shining said with a loving smile

Twilight hugs her big brother once again. “I knew you still loved me! Um, * If you want to, uh, h-hug me, the way that you want to, you c-can, because I know you do it out of love.... but p-please try not to hurt me big brother..." The purple mare said in embarrassment.

Twilight wrapped her hooves around shining for a tight hug. "I'd like that.” he says, kissing her on the forehead before moving down to her cheek, then finally her neck. All the while starting to rub his hooves down her sides to kneed her flanks. "I love you, Twilight."

Twilight smiles, letting her brother caress her. “I love you too BBBFF.” She kissed his leg and muzzled it lightly, like a child might.

Shining Armor puts his hooves under his filly sister, lifting her up on her hind legs, pivoting her and throwing her off balance as he pushed her onto her butt. He locked her lips with his own as he slowly pressed his chest into his sister, pushing her to ground. Once pinned he places a hoof on each side of her petite purple frame. He started to kiss down her body, nuzzling her small tuffs of hair, trying to be as slow and gentle as possible. Upon reaching her marehood he looked up into his sister's eyes. "Are you ready, Twiley?" He asked.

She winced at the force of being pushed and pinned, but managed a smile "Y-Yes big brother... I'm ready.”

Shining Armor looked back down at the tiny vagina in front of him. He licked his chops; salivating at the mere thought of this sweet delicacy. Shining tentatively stuck out his tongue, making it firm and come to a sharp point. He placed his tongue on his sister's skin before swirling around her honeypot, building up her anticipation. Never actually touching the lips of her opening. He slowly started to come closer and closer to her nethers with each rotation of his tongue, before flicking her clit on every other pass over."How are you doing?" He asks his sister in a gentle tone.

Twilight could feel the walls of her marehood clench, blushing and stretching her back legs outward. “It... f-feels good big brother." she said with an unsteady voice.

Shining Armor put his hooves to his sister's delicate lips, gently pulling them apart. He could smell her aroma, and could feel his large, marbled shaft stiffen under him, pressing against his stomach. He ignored his growing erection for the moment and used his flat, wet tongue to give Twilight a sloppy lick. He started with almost no pressure, just licking the surface, but soon gets greedy and started putting the force behind it to penetrate her, sliding his tongue into her tight, sweet, pussy.

Twilight gasped, clenching her legs as her brother's prehensile tongue penetrated her, exploring her vagina. She moaned, blushing a deep red. "Oh, b-brother, you've never done this before..."

Shining Armor pulled his muzzle from Twilight's pussy, his nose matted from the moisture taken from between his sister's legs. "I know, but I knew you would like this, and I want to make you feel good." He answerd his sister, breathing heavily, trying to regain his breath from an extended period buried between his sister's haunches. He slowly pushed himself up to a sitting position in front of his sister. Shining's fully erect equine cock visible by the small amount of light able to make its way into the closet. Shining sported a dick that was black at the base, along with his sheath and a heavy set of testicles. But towards the middle of his shaft, the black marbled into a fleshy pink color

"Umm... Twiley? Do you think, maybe.. you could do the same for me?"

She stared at her brother's erect cock, biting her lip. She looked up at her brother, with hesitation in her eyes. "Big brother, I don't..." She saw his face, the sweetness, kindness, and gentleness she's always known and loved about him. "...Yes, of course I will."She Finished. Leaning forward, keeping eye contact with him, she slowly brought her mouth to the tip of his member, extending her tongue and teasing it. Twilight did this slowly and awkwardly, looking for his approval, having never done this before. "L-Like this big brother?" She asked.

"Mmm...Yes, just like that Twilight. Try licking it up and down." Shining placed a hoof on her head, running it through her hair and behind her ear, not putting pressure to control her to do one thing or another, simply to comfort her and show her that he approves at all times. "You are the best sister I could ever hope for, Twilight."

She beamed at her brother's approval, then does as he suggests, moving her tongue down to the base of his cock, then back up to the tip. "You're the bestest brother any filly could ever have, Shining Armor." She returned to licking his member, moving her tongue up and down with greater force and speed .

"Oh yeah, Twilight. That feels really good. Will try to take the head in your mouth and suck on it likea big lolipop?” Shining asked his little sister.

She nods, wrapping her lips around the tip and sucking gently. She moans slightly as she presses her tongue against his member, moving her lips up and down and swathing it with her tongue

Shining Armor's rock-hard stallion cock burnt with lust. He could feel his heart beat pulse from the veins that art bulging on his dick. The white stallion could feel his cock start to pulsate in tandem with his heartbeats. Shining knew what happens next. He tried to warn his baby sister of his hair trigger but could only gasp as the sudden orgasm racked him from such little stimulation. Shining closed his eyes as he felt a few strands of semen erupt from his bucking cock. He was unaware where they landed.

"I'm... sorry Twilight, I should have warned you." shining panted as he fell to his back laying sprawled out on the closet floor.

Twilight gasped, the semen drenching her, sticking to her hooves, hair, and face. "Big brother... what is this? Why is it so sticky?". She cocked her head and manageed a smile despite her confusion. "Did - did I at least make you happy?"

"S-sorry Twiley, I should have warned you...You see, when colts really love a filly and get excited this happens... it just means I love you more than any other mare in the whole land. And yes, you made me very happy." Shining smiled at his little sister, covered in his cum she was still adorable, but with a perverted twist. "We should probably get you cleaned up....” he continued. The white stallion opened the closet door and went into the hallway, going to the bathroom, making sure the way is clear and their parents were not nearby.

Twilight followed her brother, walking as quietly as possible into the bathroom. "Brother... I'm scared. What if they find out?! They could take you away!" She began to cry and moved to hug him, but stops, not wanting to touch him with the semen coating her.

"It's Okay, Twilight. Hop in the tub, I'm going to help you wash up. And they won't find out... we will be fine..." Shining armor tried to comfort her as he turned on the water in the tub, putting his hoof under the stream testing the temperature, adjusting the knobs until it was lukewarm.

'While I'm at it, i need to wash myself off...' Shining armor thought to himself as he looked down at his semi-erect shaft and sheath and were still splattered with his cum.

Twilight climbed into the tub, slipping in slowly, then submerged herself completely, watching the sticky white strands disperse in the water. "Um, b-brother, are you coming in too?"

"Uhh yeah." Shining said after a moment's hesitation. He stepped into the tub behind his sister,and quickly washed his still semi-erect cock. Although it was now free of any cum, the rubbing and washing had given Shining another large erection. Shining bit his lip as he got an idea."I'll do your mane and back for you, okay?" Shining asked, scooting forward in the tub before waiting for a response, he felt his hard dick touch the soft, wet, fur of his sister's flank.

Twilight grinned, turning around. "Okay big brother! Gosh, we haven't taken a bath together since I was a really little filly!" she flinched slightly, feeling something touch her rear. "Uh, Sh-Shining Armor? What was that?"

"Hmmm...? Oh, it seems I never completely stopped being "excited"." Shining Armor levitated a brush that was near the tub and brought to his sister's mane. He began to stroke the wet hair, making sure no cum was left in her cute mane.

'I need to make sure she is clean before i get side-tracked with anything else'. He told himself, ignoring his erection that was starting to throb; subconsciously started to grind against his little sister's thigh as he began to sway his hips forward and back.

The purple filly let her brother brush her mane, smiling up at him. She feels his cock brushing up against her. "Um... b-big brother, does this mean you want me to, want us to... y-you know” She blushed, looking away from him.

Shining kissed Twilight's freshly brushed mane. Before casting aside the brush."Yes.” He whispered into his sister's ear. Shining shifted his cock so that it is pointed at the ceiling. He scooted as close as he could to Twilight, so she was in between his hind legs. Shining wraped the purple mare in a loving embrace, pulling her back into him so his large meatrod was sandwiched in between the two bodies. He slowly rocked his hips, letting his little sister feel his strong body. "Are you ready, Twiley?"

Twilight blushed, then relaxed, melting into her brother's embrace, feeling his security and assurance. "Yes brother, I'm ready."

Shining armor nudged her into a standing position. He stood with her, then once at the right distance away reared up on his hind legs. He planted his left hood on the edge of the tub to not put his full weight on his small sister, his right hood however, curved around Twilight's right thigh to hold her in place. Shining Armor lined his cock up with his sister's pussy; wet from water and leftover excitement in the closet. He slowly leaned forward, until he could feel his cock head at her extremely tight and delicate entrance. "I love you Twilight!" Shining near shouts as he thrusts an inch, just enough to penetrate her tiny lips with his too-big dick. Shining leaned farther into his sister, barely moving his hips forward and back, making for the slightest of movements inside his sister's vagina.

Twilight gasped as soon as he penetrated her, wincing at the pain, though she knew he was being as careful and caring of her as possible. The sensation of her brother's cock created mixed feelings of shock, pain, and pleasure in the filly, unsure of what to make of the experience yet confident that her brother had her best interests at heart. She lurched forward slightly and let out a moan. "I-I love you too, b-big brother."

Shining nibbles Twilight's ear while she gets used to the penetration of just the head of his large member. Once her moans stopped sounding painful, he leaned back so be more at a perpendicular angle from her. His right hoof slides from under her thigh to around the base of her small tail. His left hoof barely touching the edge of the tub in the new position. Ge began to pump her a more regular speed, lacing his marbled cock with her filly juices. Shining slowly started to push harder, trying to go deeper into his sister's pussy

Twiligh moaned, the shock of penetration having well worn off. Still, the feeling of her brother's cock sliding in and out of her, deeper into her body with increased pressure, filled her body with strange new sensations. Unsure of what will come, she considers asking him to stop, but she trusts him, and instead asks, "B-Big brother? Will... will this hurt?"

Shining stoked her tail with his right hoof. "No, Twilight." He gave her a big smile; before thrusting back inside her. Shining knew Twilight was tiny, but was surprised when he felt himself touch her cervix when he was only halfway inside her.

'looks like this is her limit...' Shining said to himself. Since he was able to fully penetrate his baby sister without her crying it pain he decided he could go all out. The white stallion started slow and quickly picked up speed, trying to determine how hard he could thrust without penetrating her cervix, that was the last thing they needed. After finding the ideal power he began to pick up speed to really pound her filly pussy. The sounds of her young marehood squelching permeated the room. His filly sister's cunt was like a velvet vice around his cock as he pounded away, actively trying to suck every last drop of cum out of his large balls. In such a tight, wet, hole Shining knew he would not last long.

"Uhhg... T-Twlight.... I-Im about to cum again." Shining was able to mange to moan between haggard breaths this time.

Twilight's whole body was rigid now. She felt no pain, but could feel her brother deep inside of her, and was scared he might do something bad. Still, she trusted him, holding on as he informed her that he would be cumming again, this time inside of her

In an act of both self-pleasure and curiosity, she closed the walls of her clitoris tightly around her brother's cock, and was surprised by how good it felt. "G-Go ahead brother, I want it..."

Shining Armor took a sharp breath in as Twiley's pussy suddenly tightened even more. He shuddered as his cock pulsed. His whole body tensed up.

"Oh... FUCK!" Shining swore, not something he did normally. He felt as spurt after spurt of thick, voluminous cum shoot out of the end of his now-flared cock that was buried inside his filly sister. This cumshot was much larger than his last, that much was easy for Shining armor to tell just by how much better the orgasm felt. Unfortunately, his massive load was simply too much for the little filly and soon with every new spurt of cum that erupted out of his cock, an equal amount of cum would be ejected out of her pussy into the now-cool bath water.

As his cock started to soften, and his orgasm-induced high was wearing off, Shining armor dismounted, letting a flood of his semen escape his sister's pussy. He then collapsed into the tub, his back against the back of the tub.

"That... was amazing, Twilight. YOU are amazing." Shining told his sister in the afterglow of his orgasm.

Twilight didn't move for a while, taking in the sensation, feeling her brother dismount yet still feel his warm juices inside of her. Slowly, she attempted to sit down in the bathtub, allowing the strands of semen to leak out into the bathwater. She turned around to her brother, blushing and crying, and hugs him tightly

Shining stroked her wet mane. "I love you twilight...." He coos in her ear, caressing her hair. Shining kissed her on the forehead.

"I suppose we should get you cleaned up... again;" He says, a little embarrassed. "But, then its off to bed, its past your bedtime, you know.." he said, gaining a light smirk.
