Drizzle cooed contently as he snoozed peacefully on the soft royal bed. He lolled his head from side to side as he started awakening from his peaceful nap. His eyes cracked open, and he groggily beheld a colorful form between his legs. The pink, purple, and cream colored blur was doing something really nice to his tender and limp sheath. He could feel something warm and moist washing over his sheath and sack like a mother cat cleaning her kitten.

"Did you have a nice nap, little brother?" She asked sweetly, trying to ease him awake.

"Huuuuuuuuh, big sis?" Drizzle asked, shaking off his sleepiness. Cadence giggled at Drizzle's cute sleepy face.

"You've been asleep for two hours, so I thought that I'd wake you up."

Drizzle looked around the room and noticed that his big brother was missing.

"Where is big brother?" He asked his beautiful sister, still between his legs.

"Shining Armor had to go and brief the troops. He'll be away for a few hours…And…big sis kind of…needs your help."

Drizzle sat up with a worried look. "What's wrong, big sis? Are you ok?" Cadence lowered her ears, looking away from her little brother's worried face.

"W-well, big sis only got to cum once, and she's feeling like she'll….explode, if she doesn't remedy it," she explained with a pained look.

In the couple of hours that Drizzle slept, she felt like her balls were filling to maximum capacity. And having a cute little colt sleeping right next to her didn't help matters.
Drizzle sighed and smiled at Cadence's explanation of her problem.

"Oh, is that all? Of course I'll help you, big sis."

Cadence beamed a relieved smile at the colt on his back. "Oh my dear sweet little brother. Big sis love love loves you so much!"

Drizzle couldn't help but blush. His big sister was so pretty and kind, how could her not help fix her ailment? Drizzle started rolling over, when Cadence stopped him.

"Oh, um…Drizzle? Big sis wanted to try something with you. Just stay still for a moment."

Drizzle didn't have time to react or ask as Cadence lit her horn up and applied her magic to Drizzle's nethers. In a puff of smoke, drizzle saw what she had done.

His small sheath and balls were mysteriously missing, and in their place was a smooth, puffy little pussy. Drizzle went pail. His mouth hung open as Cadence gazed fondly at her good work.

"I-I-I-I'm a…a-"

"Yes, you're a filly now," Cadence stated mater o factly. Drizzle sputtered and tripped over his words as he tried to comprehend what was happening.

"Calm down, sweetie. It's only temporary. It'll go away after you've satisfied me."

Drizzle looked pleadingly up at Cadence, who had donned an insane glint in her eyes.
"B-but big sis! I don't want to be a girl! Please change me back!"

Cadence's sexualey induced madness was halted at the sound of her little brother's scared pleading. She hated hearing him sound so scared, but she really wanted to plow him as a filly. Luckily, Cadence came up with a solution.

"Shhhhhhh~," she cooed, placing a hoof to Drizzle's lips. "I know this seems strange, but I have an idea. If you let me do this with you, I'll let you…do me."

Drizzle seemed to calm down and look curiously at his big sister.

"W-what do you mean?" He asked. Cadence rolled onto her side and opened her back legs, revealing her pristine, pink pussy.

"You've never done 'that' before, have you?"

Drizzle gulped. Mommy had never let him do 'that'. and he would be lying if he said that he had never thought about it.

"You mean…I can..?"

Cadence used a hoof to gently open her lips, exposing the red, wet insides of her flower.

"Thats right. Just imagine it. Thrusting inside your big sister's tight, wet snatch with your cute little…"

Drizzle gulped again.

"Ok, big sis…I'll do it"

Cadence licked her lips and re-dawned her crazy look. "Heh heh, I thought that you would agree. Now, we need to come up with a new name for you."

Filly Drizzle cocked his, uh, her head, looking confused. "Why do I need a new name, big sis?"

Cadence placed a hoof over the whole of Drizzle's new pussy. "You're a girl now. We can't call you "Drizzle" now that you're a filly." Cadence tapped a hoof to her chin thoughtfully.

"Ah! How about Droplet? That's a cute name. Do you like it, Droplet?"

Drizzle blushed, feeling strangely sheepish all of a sudden. "I…I guess," he meeped, hearing that his voice was now more feminine.
Cadence giggled at the cute sound of Droplet's filly voice.

"The spell is taking full affect now."

Cadence lowered her mouth while keeping eye contact with Droplet. Her tongue swiped up and down her little sister's puffy slit, reveling in the delicate taste of Droplet's pussy. Droplet released a little shriek when she felt Cadence's tongue make contact with her slit.

"Mmmm, you taste wonderful, Droplet," Cadence purred to the blushing little filly. Droplet covered her cheeks with her hooves. She felt so nervous and excited as her big sister teased and touched her private parts. Cadence eyed Droplet's tiny titties. They were only little pink nubs under her belly, but Cadence drooled at the sight of them none the less.

She swirled her tongue around both of the little teats, matting the fur around them as she salivated over them like a hungry beast. Her lips pursed, and she captured a nipple in her mouth, nomming on it gently with her teeth.

Droplet bit her lip. Big sis was really good at sucking nipples. It felt so good, and Droplet felt her new parts start to drip and get warm. Cadence smelt her little sister's growing arousal with all the proficiency of a stallion sniffing out a mare in heat.

"You smell so ripe, Droplet. Are you aroused from your big sister?"

Droplet closed her eyes. She didn't know why she felt so embarrassed and hesitant to Cadence. She flinched a bit when out of the darkness she felt a pair of soft, warm lips touch her forehead. Droplet opened her eyes to see her big sister smiling at her.

"It's ok. There's nothing to be afraid of. I'm here for you, my sweet little sister."

Droplet suddenly felt much better. More calm and relaxed than before. "W-will you be gentle with me?" Droplet asked.
"I can't make you any promises, Droplet. I-I'm about to loose my mind as it is."

Cadence's eyes got crazy again. Her will power was hanging by a thread, and the growing stink of filly pussy and her own dick was making her even crazier. Droplet squeaked from fear, and that pushed Cadence over the edge.

"Spread your legs, you little slut! I'm going to pop your cherry, now!"

Cadence forced Droplet's back legs open wide as her hard veiny cock appeared and poised itself at Droplet's puffy little lips. She would have fought back, but big sis had her, and she wasn't going to let her back out now.

"Clench your teeth, slut! Here I come!"

Droplet clench her teeth as she felt the fat head of Cadence's cock slide without mercy inside her tight, virgin pussy. Cadence breathed through her teeth as she felt her little sister's snug walls cling and coil around her rigid shaft. Soon, both big and little sister felt the thick head make contact with Droplet's virgin membrane.

"Droplet…I-I'm so sorry, but I can't stop. This is gonna hurt. Cling to me, and I'll try to make it fast." Cadence's words reached the squirming filly. Droplet wiped a tear from her face and nodded as she whimpered.

Droplet wrapped her forelegs around Cadence's neck and held on tight as she waited for her big sister to take her completely.

One hard thrust and a loud grunt from the princess of love signaled the end of her little sister's maidenhood. Droplet was frozen in a warp of pain and fire that consumed her belly and inner walls.

"Kuuuuuuuu! You are so fucking tight, Droplet!" Cadence cried out. She felt her princesshood getting squeezed to death inside a little filly's snatch. Droplet drew in deep breathes, feeling the pain gradually fade away and being replaced by a feeling of fullness. Cadence stayed deep inside her till she felt and heard her breathing become more calm and relaxed.

"Does it still hurt, Droplet?"

Droplet lightened up on her death grip and sighed into Cadence's warm chest. "I-it still hurts a little, but I think I'm ok," she cooed, blinking to take away the sting in her eyes.

Cadence felt relieved that she wasn't hurting her little sister too badly, she didn't want Droplet's first time getting vaginaly penetrated to be a bad one. Slowly she drew out, her body quivering from the sweet sensation of having her cock hugged by a tight pussy. Cadence pulled out to the head before pushing back into Droplet's welcoming depths.

Cadence felt Droplet's tiny cervix on the tip of her cock. She pressed against Droplet's tightly puckered cervix, trying to gain entry to her resisting womb.

"Big sis, no! No more will fit!" She cried out as Cadence tried to breach her most inner sanctum. Cadence couldn't hear her little sister's please through the throbbing in her head. She used all her might to ram her thick head past her cervix, and pop inside her womb.

"You love this, don't you, BITCH!? You love having big, fat cocks ram inside your tight cunt! I'm gonna fuck you till you can't walk right anymore, you little FUCKING SLUT!"

Droplet lost her breath as she felt Cadence's cock enter her secret baby room. Cadence screamed in wild delight as her cock head bottomed out inside Droplet's womb. Cadence twitched wildly, her tongue falling from her mouth and spilling her thick saliva onto Droplet's face.
Droplet felt like Cadence had shoved a thick piece or red hot metal inside her broken slit, but she couldn't deny that she loved the feeling of being so full.

Cadence was sweating like a hog, and the smell radiating off of her was thick and stinky. Cadence was really enjoying being close to balls deep inside her new little sister, but she really needed to splooge before she exploded.

"Droplet, sweetie…big sis is gonna…..FUUUUUUUUUUUUCK~!"

Droplet's tiny cavity was instantly flooded by Cadence's thick, thick fluids. Cadence put her hooves on Droplet's shoulders, holding her in place as her head expanded, giving her batter thick cum nowhere to go but deep inside the little filly's snatch.

Droplet screamed in her girlish little voice from the feeling of having hot jizz blasting inside her, filling her womb and expanding her insides till they protruded out her belly. Droplet's eyes rolled into the back of her head, unconsciousness threatening to take over from the sexual overload her big sister had given.

Cadence had emptied more than twelve ounces of her splooge into the spent filly, but she remained as hard as she was before. She had to use force to pry her ridged shaft from her filly lover's tired hole. After a minute of pulling and prying, the engorged head of her dick finally popped out of Droplet, followed by an oozing of her cum. Cadence panted as she watched her milky seed pour from her little sister's winking pussy hole. Droplet groaned, and her body twitched as she passed between asleep and awake.

"B-b-big sis," she panted between convulsions. "Y-you came soooo much. I'm completely filled to the brim."

Cadence could only hear her own heart pounding in her chest and echoing in her ears. Her vision began to blur, a sign that something she didn't want to happen was going to happen. Her mouth became dry, but she tried to whisper the words to her now in danger little sister.

"D-Droplet……..run."

But Droplet was still too out of it to comprehend, and by the time she looked up at her sister, her sister was gone.

In her place sat the shape of a mare with glowing red eyes, surrounded by a litany of writhing and squirming cock like tentacles.

Droplet only had a moment to look in horror at the monster her sister had turned into. The red, pulsating limbs all charged at their target and swarmed her without mercy. Droplet screamed as she was lifted into the air like she weighed nothing. The tentacles all wrapped around her. Her legs, her waist, even her throat, chocking her a little till a tentacle emerged in front of her scared face.

"No!" She screamed, turning her head to the side. But the tentacle didn't care that she was unwilling. It forced its way into her mouth and right down into her belly, where it squirmed around like an eel in a bucket, clogging her throat and moving back and forth to fuck her mouth.

Another tentacle slithered up and down her oozing slit as if to lick it before it forced in all the way to her cervix. A third tentacle poked and prodded at her yet untouched asshole, secreting the same thick semen to lube its penetration. Droplet's eyes shot open when she felt the appendage ram its way into her butthole and deep into her guts.

Droplet tried to squirm free, but the act was like a pig on a spit trying to escape, and that was what Droplet was at that point, meat.

Cadence was gone for now, replaced by a demon of lust and depravity. Cadence was normally able to control this other side of herself, but seeing Droplet on her back, dripping cum from her little cunt pushed her to the edge of sanity. There was nothing to be done at that point but let Cadence work the poison from her system.

The cock in Droplet's mouth expanded as it moved faster and rougher between the little filly's lips, sloshing inside her stomach and making Droplet feel like she was going to puke. The one in her pussy came immediately, expanding and bulging her belly even larger than it already was. Droplet screamed as best she could, feeling the white hot cream flood inside her once again. She felt like her whole body was melting from being completely wrapped and filled by cocks. For a moment she even forgot that she was a boy.

The cock in her ass was ramming like a piston in and out of her tiny shit hole, and Droplet bounced and swayed from the hard fucking her ass was getting.

The cock in her mouth swelled as it pulled itself from Droplet's mouth. Droplet gasped when the end finally came up her throat and exited her mouth, only to have it spew a continuous stream of batted on and at her face. Her mouth opened out of instinct, and she let the stream pour into her mouth and pool up till it overflowed and ran down her chin. She gulped and sloshed her tongue around, tasting and eating the cum that was so thick she could have chewed it.

The cock in her asshole became furious. It shrank down in size a bit, but only so it could do what it was about to next.

It snaked and coiled through Droplet's innards as it entered her stomach. It had a clear shot now.

Droplet's half lidded eyes went wide as the moon and she screamed out in horror as she felt the anal cock come up her throat and out her mouth, silencing her once it had emerged.

Droplet really did pass out. She was so mortified that she had been completely run through that her mind couldn't handle it and shut down. The tentacle lifted its prey vertically, and Droplet sand further down on the impaling tentacle.

The impaled filly was brought closer to the form that was once Cadence. A long and dripping tongue emerged from the monsters mouth, which was lined with teeth like a shark. The monster ran it's grotesque tongue up Droplet's entire body, lapping up her sweat and other fluids.

In her unconscious state, Droplet's pussy exploded with a torrent of piss. A sight that wasn't wasted by the monster. It squirmed it's tongue to its prey's helpless little pussy and began slathering it with it's saliva dripping tip. It wormed its way inside her used gash and slithered up and into her already filled womb.

A simple poke caused the stuffed womb to erupt like a broken water balloon, expelling the excess semen. The demon lapped up and swallowed its own jizz greedily, making foul sounds of delight as it drank and swallowed. It's impaling tentacle was reaching its limit, and the monster knew it was time to finish it. Wrapping a tentacle around Droplet's middle, it started lifting the sleeping filly till the tip was almost back inside her mouth. It violently slammed her back down, an unearthly groan of pleasure echoing from the monster.

Droplet was now being used as a filly sex sleeve for a demon of sex. Again and again it raised and slammed back down the foal impaled on it's disgusting length. The demon only smiled it's toothy grin at the pure pleasure and depravity it was inflicting on one so innocent and young. It's other tentacles continued to squirm and writhe, as if they too were enjoying the show.

To someone watching, it would look like what it was. The demon was literally using Droplet to jerk itself off. And it looked like it was enjoying it. The tentacle holding her by the waist would vary it's pumps between deep and shallow, fast and slow, top and bottom. All the while moaning and making raspy grunting sounds as it ruthlessly bet off with the filly.

It's pumping got faster and more violent. Droplet's limbs swayed and jostled as she was fuck through her body with the hard and swelling cock, which was getting ready to give her the mother of all loads.

The monster grit it's sharp teeth and swelled it's cock as it exploded like it was a fountain being turned on for the first time. Every tentacle pointed at Droplet and gave her a firing squad bukakke.

The sweet sleeping filly was quickly turned into a dumpster for the tentacles around her, which glazed her entire body with thick ropes and streams of their milk colored slime.

After two minutes of cum flying and splattering on Droplet's face and body, the monster lowered it's conquered prey. As soon as it's last tentacle was removed, the monster put a hoof to it's head and groaned loudly in pain.

Cadence came back in control and forced the demon back inside it's cage deep inside her. Her body reverted from one with many tentacles, to one of a kind and slender mare. Cadence winced and fell to the floor, feeling like she just went ten rounds with Bulk Biceps.

Regret and worry hit her like a meteor, and she weakly dragged herself to the foal sleeping on the bed, now turned back to the little colt that it was. She looked the cum covered colt over, feeling relieved that he was still breathing. She wiped some of the cum from his face and nuzzled him.

"Drizzle? Drizzle sweetie. Please wake up for me now," she pleaded on the brink of tears to the sleeping colt.

Drizzle started to stir, his big eyes fluttering open. The blurry image of his beautiful big sister was like a breath of fresh air to the groggy foal. He smiled up at Cadence, yawning as he awoke from what felt like a really good sleep.

"Nnnnnnn, hi, big sis," he whispered.

Cadence was so happy she couldn't hold back the big fat tears that fell. He was ok. He sounded better than ok.

"I'm so sorry that I lost control, sweetie. Did it hurt you?"

Drizzle blinked a few times, shaking his head slowly.

"It was a little scary, but also….kinda exciting," he explained, sounding refreshed.

Cadence sighed in relief. She looked down his body, her eyes locking onto something interesting.

Drizzle was hard, and sticking out of his sheath.

Cadence smiled. Shining Armor almost had to be hospitalized after he met with *it*, but Drizzle came through with flying colors. An impressive feet, for an earth pony colt.

"Do you still want to put it in big sis?" She asked in a gently babyish tone.

Drizzle picked his head up and smiled.

"Uh huh," he replied affirmatively.

There was only one problem. Drizzle could barely move, let alone rut. Cadence saw the disappointed look on his face. He had gone through so much, how could she not hold up her end of the deal. As a princess, it's important that she keep her word.

"Just relax, little brother. Big sis will take care of everything."

Using her magic, she lifted the little colt over and held him at the entrance of her sopping cunt and aimed him at his mark. She pulled him in and treated Drizzle to the most warm and welcoming hole he had ever been inside. Cadence winced as she tightened down oh his inexperienced cock, flexing as if to pull him inside deeper.

With no effort, Drizzle was balls deep inside Cadence, even if it wasn't very deep.

Cadence sighed loudly. Sure his cock wasn't very long or fat, but she got an electric tingle from the idea that her little baby brother was being lovingly held inside her pussy.

"H-how is it, your first pussy?"

Even though he wasn't able to fuck on his own, Drizzle was in pure bliss from feeling his sensitive pink dick inside Cadence's warm, moist hole. Now everything made sense. Why mommy and aunty loved having sex with his ass. Cadence hummed to him as she swayed his hips back and forth, in and out. Almost like she was playing a little game with him.

Drizzle closed his eyes and sighed, shivering from the pleasure he was receiving. His little cock made tiny sloshing sounds as it dipped in and was removed. The smell of the princess's musk as thick in the air.

Putting your dick inside feels amazing.

"B-big sis! Something is coming! What is it!?"

Cadence knew exactly what it was, and Drizzle's panicked cries told her he had never had one of these before. She smiled wickedly. How would her aunt Celestia like it if she took both Drizzle's virginity, and his first orgasm?

"It's ok, honey. Just let go and release it inside me as much as you can."

Drizzle closed his eyes as Cadence slid him in slowly all the way. He came as soon as his pelvis touched hers.

He squealed with such delight as his little spurts of clear cum left their home in his balls and made their new home in Cadence's vagina. Cadence experienced her own mini orgasm, mostly from the feeling and idea of Drizzle having his first cum.

It was over as soon as it happened, and Drizzle fell onto Cadence, already asleep. This time, out cold, down for the count.

Cadence allowed herself a minute to breath. She could almost feel his cum inside her, like drops of warm water had fallen inside her. She set herself to cleaning up the mess in the room and on her little brother.

Once the last puddle of cum was up, she was quite tired herself. She got in bed with Drizzle and cover them both up.

Cadence used to sleep with Twilight when she foal sat for her. Obviously she had never done with Twilight what she had just done with Drizzle. It was the only way she could get Twilight to take her naps, and Cadence didn't mind at all.

Funny how some things don't change.

To be concluded.
