With their mom gone for the week, the sparkle siblings have some fun together.

With their mom gone for a week long vacation, what better time for the two Sparkle siblings to let loose. Most siblings would take the time to play games, watch movies, or both at the same time. Shining and Dusk are not normal siblings.

Contains: Incest (duh), Gay stuff, Chastity, Strong Dom/Sub themes, Rule 63 Twilight

For once not foalcon, this is human so both Shining and Dusk are above the age of consent.

Day 1

“Alright, we’re about ready to head off!” Mrs velvet announced, a small travel bag in her hands. “Take care of the place now, won’t you Shiny?”

He quickly snapped into a mock salute, “Yes ma’am, the house will be firmly in my hands.” Though he couldn’t keep the smile from spreading across his face.

His mom seemed to appreciate the humor though, giggling softly to herself. “Thanks Shiny, it makes me feel so much better that you’re here to look after the place” She picked up the bag, turning to walk towards the door.

Shining followed her, “What, you think Dusk couldn’t look after the place by himself?” A knowing look from Velvet caused him to laugh as well, “Right, silly question.”

As the pair approached the door, she gave one last hug to her son. “Take care now, I’ll miss you.”

“Mom! You’re going away for a week, not forever.” He admonished, though he still leaned into her embrace, “Now get going, you’re gonna miss your flight if you don’t”

With what felt like another dozen waves goodbye, Velvet sat into her car. With a short splutter, it fired up to life and began to back up out of their driveway. Well, not before another wave. But after that, she actually began to make her way to the airport, leaving the house completely quiet. Well, quiet for now.

“Dusk! She’s gone!” He shouted down the hallway, cupping his hands next to his mouth.

Almost instantly, there was a clutter of noises from up the stairs. As doors opened and the sound of footsteps rushed down the steps. Before long, the person responsible for the noise came into view. His brother, Dusk Shine.

He wasn’t wearing much of note, just a plain gray set of sweatpants and a loose fitting shirt. “She’s gone?” He asked, his eyes wide.

“Took forever, but yes she just left.” He explained.

With the way Dusk’s eyes lit up, you’d think he just been given the world. His smile stretched to the edges of his mouth. “So does that mean we can start…” He asked hopefully, his hands clasping together.

Shining just nodded, the silent go ahead more than enough for his brother to rush back upstairs in excitement. He had a somewhat unusual relationship with his brother. What started as an accidental walk in at the wrong time, turned into teasing. A couple drinks between the two had led into Dusk letting loose really how much he enjoyed the teasing. Which was a lot.

The footfalls returned quickly, as Dusk rushed back down the stairs. This time carrying an inconspicuous plastic bag. The essentials, he’d grown to calling it. Dusk handed him the bag, which he accepted with practised precision. “Alright, you know the drill” He instructed, “Strip, and present yourself”

With a quick nod and shaky hands his brother reached for his shirt’s hem. After his fingers found grip, he pulled it up and over his head in a single motion, revealing his rather unworked chest. Unlike Shining who was a royal guard, in training, Dusk preferred to spend his time studying and reading, which left him with a clear lack of muscles.

He didn’t have long to stare, as Dusk quickly gripped his waistband and in a similar motion thrust it to the floor. This revealed something much more tasty, his brother’s semi-hard shaft. It was by no means small, several inches long even now, but he knew the boy could grow. Hanging underneath the incestuous cock, was a weighty nutsack. It swung freely under him, twitching slightly with both the exposure and arousal.

Finishing the strip, the boy kicked his clothes to the side. He wrapped his hands behind him as he stood proud with nothing to shield him. Beginning his “inspection” Shining began to slowly walk around his nude brother. Admiring his form from all angles. Dusk did put a lot of work into his appearance, he could tell. There was not a single strand of hair anywhere on his lower body, all trimmed down to invisibility.

Stepping close, he pressed a hand against his brother’s ass. He heard a soft moan as he gripped the soft flesh, though his true goal was between the cheeks. Dusk’s anus was cleaned to perfection, and as he rubbed a hand over the soft hole he could even feel the lubrication he had clearly applied just before coming down.

Having passed, Shining stood back to be in front of his brother who was staring back with hopeful eyes. “As good looking as ever, I’d say you’re ready” Dusk pumped his fists in the air, his cock jumping with them.

Smiling himself, he reached into the bag grabbing a small box from within. “So, mom’s gonna be gone for a week. You know what that means?” He asked, almost rhetorically

Nonetheless Dusk answered, “It means I need to be a good slut for my brother. Tend to his every need until she returns.” His cock continued to grow as he spoke, though his eyes were firmly locked onto the box.

Pulling off the lid, he revealed what was inside. A simple metal chastity cage. He pulled the ring out of the box, grabbing his brother’s cock with his other hand. With no hesitation he slipped the ring back, slipping the nuts through the ring, letting it sit snugly against his smooth groin.

Next came the cage itself, the hard part. Wrapping his fingers around the shaft, he slowly worked the skin forward into the metal enclosure. Inch by inch working the two halves of the whole together.

After what felt like together, the metal of the cage bumped into the metal ring. Taking a key from the box, he twisted the lock shut. Sealing them together, for now. He looked up at his brother’s face, he’d been biting his bottom lip clearly trying to hold in something. With one last grope, he stood up to stand above his brother. “What are you?”

With a dry gulp, Dusk responded. “I’m your slut”

Shining took a few steps closer, “And what will you do for your brother?”

Dusk could only stare up, “A-anything he asks”

He bumped into his nude sibling, “And when will you cum?”

“Only when my big brother lets me”

“Good~” Shining pulled away from his brother, “Alright, I’ll let you know when I need you then.”

Shock filled Dusk’s eyes, “Wh-wha.. You mean you don’t want to fuck me now?”

Shining nodded to the affirmative, “That’s what I said, I’ll call you when I need you.”

This clearly didn’t sit right with him, as he squirmed on the spot. But he realised his lack of ability to complain, “If that’s what big bro wants…” He replied, dejected.

It was mean, he knew that. But he knew that Dusk would love it in the end. He always did. He picked up the bag as he walked over to the sofa. Obediently, Dusk followed him curling up into a ball next to the foot of the seat. They still had plenty of time left in the week.

Day 2

Buzz Buzz

The buzz of his phone, and the harsh blue screen, woke Shining from his slumber. With a groan, he sat up on his bed. A naked arm wrapped around his waist, almost making him jump out of his skin before he remembered who was there. His brother, Dusk Shine, was laid next to him without a single drop of clothing. Well, aside from the metal cage around his cock.

“Good morning bro” he said dutifully, “Did you sleep well?”

“Not really,” he lied, “But maybe some little slut wants to make up for that?”

With the gleam that appeared in his eyes, you’d think he was offered the world. Dusk practically dove down the bed, placing his head instantly against his brother’s groin. He shifted aside the underwear he was wearing, taking no time at all before wrapping his lips around his currently flaccid shaft.

“My my, someone’s eager” He commented, “You must be really pent up”

Dusk blushed, though didn’t pause in his ministrations on his shaft, which was quickly growing in size throughout his mouth. Shining let his hand roam around his brother’s backside, eventually settling on the caged cock. There was a considerable amount of pre already dripping out of the cage, a testament to his brother’s arousal. He moved his hand backwards along the cage, feeling the shaft twitch underneath as he did.

Next were the balls, sagging freely underneath. As he wrapped them in his hand he felt his brother moan around his shaft and his own giving a twitch. “When was the last time you got to empty these?” He asked, squeezing them softly as he did.

Dusk pulled off his now erect shaft, a strand of drool connecting the two. He let out a shaky breath before answering, “Th-Three days, it’s been three days.” Dusk kept his hands on his cock, not daring to let it go soft.

“And why did you cum?” Shining pressed. It wasn’t that Dusk was forbidden from cumming when they weren’t together, he just knew what buttons he liked pressed.

And from the intensity of the blush on his brother’s face, he knew he hit it on the head. “I-i was training… For you..” he admitted, though when Shining didn’t speak up he forced himself to continue. “I was riding number three, thinking about you obviously, and oh god it just sprayed everywhere.”

Number three was of the training dildos that Shining had bought for him, back when they first started getting serious. According to Dusk it was the one that most “felt like him”. Even though it was quite the old toy by now, there was a small warmth in his heart knowing it was still so important to him. “And now you’ve got the real deal in front of you.”

Dusk nodded feverishly, darting his eyes back to get another look at his shaft. “I wish I could be under it forever…”

As much as they loved doing over the top things like this, it was very hard to do with their mother in the house. What little time they had with her being out or busy was frequently just spent with quickies or short sessions. It was very rare that they had time like they had now.

“Alright, go grab the lube. I want a piece of you” He commanded, though he could barely finish the sentence before his brother was up and away. Dusk opened up the top drawer, and with one motion grabbed the bottle of lube that was carefully hidden at the back. Holding the bottle in his hand he asked, “Do you want to lube me, or should I?”

Shining sat up in his bed, “Pass it here, you’ve been good so far” He said, holding out his hand. Dusk stepped back to his bed, giddily dropping the bottle in his hand. Without a word of instruction, Dusk jumped onto the bed and bent over presenting himself to his brother.

Shining uncapped the bottle, slowly oozing out the artificial lubricant into his hand. He rubbed two of his fingers into the lube, coating them completely, before placing them at the rim of his brother’s anus. It took only the slightest amount of force for the well lubricated fingers to pierce through the used hole. Before long, they were deep into the knuckle. Dusk moaned out as his brother’s fingers rubbed against his prostate.

Pulling his fingers out, now with much less lubricant on them. He pointed the bottle at his own shaft. Although there was still a good amount of saliva on his shaft, he knew from experience to never go low on the amount of lube. With that thought in his mind, he squirted a health amount all over his shaft. With his other hand, he rubbed it in, getting the entire shaft nice and slick.

With all the prep done, he looked back over at his brother who was staring back at him with his lower lip bitten. Shining moved up the bed, mounting on top of his brother. He pressed the tip against the tight hole, just barely not penetrating it. He teased the hole, rubbing his shaft up and down against it.

“Shiny! Please!” Dusk cried out, “I need you in me”

Shining thrust his hips forward, true to the request he wasn’t slow or gentle as his hips slapped against his brother’s. Dusk moaned out, though without a hint of pain in his voice. As he pulled his hips back, Dusk's followed his, desperately clutching onto his shaft. Once only the tip was inside, Shining replied with another harsh thrust.

As the pair got into their rhythm, dusk leaned further forward onto the bed, his arms shaking. He was already breathing heavily, mouthing his brother’s name under his breath. As Shining continued to pound, he felt the hole seize up drastically. He then heard the soft sound of liquid hitting his sheets. A quick look confirmed his suspicions, a white puddle sat under his brother’s crotch. “Did you just cum?” He asked rhetorically, not stopping his thrusts as he did.

Dusk didn’t respond immediately, his tongue lolling out of his mouth as he lay on the bed. After a few seconds, he seemed to come to his senses, his eyes focusing back onto his brother. A strong blush formed on his face as he meekly nodded, though that didn’t stop him from thrusting back towards his brother.

Picking up his brother by the hips, he shuffled backwards until Dusk’s face was next to the puddle he made. He grabbed his face with one hand and forced it downwards into the messy sheets. “Lick” He commanded, a single word was all that was needed to force his brother to start eating his own cum off the sheets.

As his brother ate the results of his orgasm off of his sheets, Shining felt his own rise. Without a word of warning he began quickening his thrusts, pushing himself closer and closer to his own orgasm. To his credit, Dusk did seem to understand what was happening as he moaned into the sheets.

Bottoming out one last time, Shining thrust his hips forward. His shaft twitched and filled with cum, depositing load after load deep inside his brother’s ass. After what felt like an eternity, he flopped back. His shaft pulled out with him, a small amount of cum flowing out of the gaping anus.

Dusk stood up from the now cum-free bed, and made his way back over to the dresser. A quick rummage later returned a small shiny butt plug, which he quickly inserted. Returning back to his brother, who was now laid back on the bed, he curled up next to him. “Thanks Shiny”

He wrapped an arm around his Dusk, “What else is a big bro for?”

The pair smiled at each other, resting for just a moment before the real day began.
