Pounding Flurry

Pound awoke, groaning softly as he found sunshine blaring into his eyes, shifting in bed to face away from the glaring ball of light. As he felt his fur tugging a little, as though clumped together, he found that it indeed was stuck together with something sticky that had dried in it. Suddenly, he remembered the previous night; seeing his parents hugging weird, his pee-pee getting all hard, then that lovely feeling that had happened when he'd rubbed it, ending when they got even stronger and some sort of white goo came out of him.

As he looked down, Pound saw his fur was matted together with something clear and very sticky, like that time he'd spilled apple juice on himself and it had dried. He tried to remember if he'd spilled something on himself before bed, but all he could remember getting on him was that white goo from his willy when it—

"Pound, Pumpkin, it's time to get up! It's time for that job we've been talking about! We're also going to be having a special guest here too, so get in the shower before they arrive! Pound, take the master bedroom's shower. Pumpkin, take the downstairs one." Mrs. Cake's called upstairs, making Pound jump as he realized something. His thingy was hard again.

Pound was slightly panicked as he saw that, not understanding why it was out now. He wasn't watching his parents hugging or anything else, he was alone in his room, yet here it was, stiff again. Tentatively, he touched its top part again, feeling another tingle of that strange sensation go through him and his pee-pee pulse again. When he pulled back his hoof, he found more of that clear, slippery stuff on his hoof again, confusing him further.

"Pound, I'm not kidding. We're on a time limit here! Get up and get in the shower, NOW!" his father commandingly yelled up this time, startling Pound from his stupor. Getting up again and feeling his willy hanging heavily below him now, he started walking, feeling it slapping his inner thighs with each shift of his hips.

As he entered his parents' room, he looked over to the bed, giving a soft shudder as he remembered what he'd witnessed happening on that bed, his still stiff pee-pee giving a throb. That strange, earthy-musky scent was still there from the previous night; the one that made his mind go numb and made him want to climb on something and start moving his hips for some reason, the scent that now made his penis throb, a bit of wetness landing on his underbelly as the thick tip of his colt-thingy slapped against his belly.

Eventually he made it to the bathroom, turning on the shower and waiting for the water to warm. As he waited, Pound had started subconsciously rubbing his length, not realizing it until his hips were rocking hard and nearly making him fall off the tub's edge. Showering quickly, focusing mostly on his sticky belly and chest, the scent of lemon soap cleansed his nose of what was, unknown to him, his mother's pheromones. Pound was starting to feel normal again as he stepped out of the shower, feeling like he had before the previous night. His thingy was where it belonged, in his sheath.

Pound made his way quickly through the room while holding his breath, making his way out to the hall and proceeding downstairs, not wanting his pee-pee to come out again after what his father had taught him about it being his 'private area' when he was younger.

Pound made his way downstairs, following the scent of breakfast – before seeing Princess Cadence and her husband Prince Shining Armor in their dining room! Immediately he fell to a bow before the royal couple.

"Hey, it's OK Pound. Please, stand up. I wouldn't want to deny a foal his breakfast just by being here." Shining said, before nodding to the food-filled table. Pound also noticed that Cadence was talking to somepony else and, as Shining Armor moved aside, Pound saw that she was talking to their daughter Princess Flurry Heart, who Pound knew was about two years younger than Pumpkin and himself. They'd always been friendly ever since they'd first met her many years ago, but given that they lived so far away they rarely got to see each other.

"Hi Flurry!" Pound said when Cadence finished talking to the little light-magenta filly and telling her to behave, her tri-toned mane, composed of strips of light cerise, arctic blue, and violet – taking after her mother and father both – and naturally, tightly curled. He saw as her opal-blue eyes widened as she saw him and earned a smile, getting a wave of her hoof from the friend he hadn't seen in months.

As he looked over to his twin sister Pumpkin, across the table from him and eating her pancakes and eggs, he saw as he did every day that her coat was a lemon yellow, her bright-orange mane in its usual light-blue bow, and her azure-blue eyes regarding her brother with a neutral interest. "Morning sis." Pound said, receiving a nod in response given her mouth was full.

"Now, I'm sure you're wondering why the royal family of the Crystal Empire are here, and what this mysterious thing your parents are helping me with." Shining Armor asked, getting a nod from the resident twins, "well, Cadence and I are going to be putting on a big celebration for our next anniversary which is in a few days, and we want it to be kept on the down-low until the official announcement is made. As such, we need to have Flurry stay somewhere and be watched while your parents help me set it up. Your parents also needed somepony to watch you, so we all agreed you could all be watched by the same pony."

"What? Who?" Pound asked and, as if on cue, a pink streak raced by.

"Ooooooooo, this is gonna be so fun! Watching three little foals AT ONCE?! I thought it was fun watching two before but, OH BOY ANOTHER ONE TOO?!" Pinkie Pie exclaimed as she pronked in place, the pink-coated mare's equally pink but darker, curly mane bouncing with each, with her clearly very excited to be the chosen pony.

"Fillies and colt, Pinkie Pie will be...watching over you today." Cup Cake said with some reticence, though she knew Pinkie was generally a reliable pony when she'd watched over the twins before on occasion...plus the fact that everypony else she trusted was either too busy to foal-sit today, or were involved with setting up the celebration.

As Shining nodded towards the doorway and the other three adults noticed the time, they all headed towards the door after giving their foals a hug and kiss goodbye. "Pinkie, remember, lunch is at noon, dinner's five, and...well, Your Highnesses left a list for Flurry and you already know all about Pound and Pumpkin..." Cup Cake said as she filed out the door, "...bye my precious little ones...I'll see you later today!"

"Bye Flurry, we'll be back later. I'll see you tomorrow morning! I love you!" Cadence said, before they were gone. With that, Pinkie was alone with the three foals. Smiling brightly, she quickly thought of all the things she could do with them. Her mind, however, settled on baking.

"So anyways you three, today I thought you could help me with...baking!" Pinkie said, smiling widely, "Doesn't that sound fun?"

The three foals smiled, Pound and Pumpkin always liking to hang out with Pinkie because she was so relatable to them, and Flurry simply liking to be offered something fun to do, this being her first time being watched by Pinkie. The trio nodded. "Great, let's get to it then!" Pinkie said enthusiastically, rushing off to get the supplies.

~

An hour, and somehow twenty or thirty batches of sugary treats, later, Pinkie Pie was passed out on the couch in a combination of exhaustion and a sugar coma, the twins and Flurry simply looking down at the sleeping pink-coated mare. Another thing the twins very much liked about her foal-sitting them was that she'd usually exhaust herself doing something then pass out, leaving the twins free reign of the house.

"Well, she's out again." Pound said, giving his sister a smirk, "You thinking what I'm thinking?"

Pumpkin nodded, an eager smile forming on her face.

Flurry was clueless what was going on.

After they were sure Pinkie was still sleeping, they proceeded. "Tag, you're it!" Pound said, before darting off, trying to keep his giggles muffled, though they both knew Pinkie was a very deep sleeper. After some previous testing, they found that it would take nothing short of a manticore roaring to wake her up!

Pumpkin darted off after her brother with her own restrained giggles sounding out, chasing after Pound around the top floor of Sugarcube Corner. "C'mon Flurry, let's play!" Pumpkin called out to her, making the alicorn unsure.

Flurry didn't seem too keen on that idea. "Um...aren't we supposed to be watched by Pinkie? I mean, what if one of us gets—"

A loud crash sounded out, though Pinkie only lightly stirred

"—hurt..."

Pound had crashed into his sister in a hallway as she'd not taken the turn into his room that he'd expected her to, ending up with the two foals in a pile, Pumpkin underneath Pound and each facing the others' rear end, Pumpkin's tail draped over Pound's head. Pound caught sight of what lay under her tail – her small, tight-cinched thingy, some different, smaller things beneath it – his memories of the previous night came back in full as he also smelled a familiar yet different scent from her. Like his mother's, but...younger, softer.

The scent was distinctly his sister's, smelling very feminine, but also a lot less earthy and had a much lower intensity 'pull' than what he'd smelled the previous night. It was lacking that musky scent that had seemingly driven his mind and willy wild. It felt like it was still kind-of 'calling' to him, but it was 'calling' to his nose instead of his ears. It was making him feel funny in his chest the same way he had felt last night...and in his sheath as well. Speaking of sheathes...

"You OK bro?" Pumpkin asked, slightly dazed from the collision, but didn't receive a response. Then she noticed that Pound was seemingly looking at something under her tail. "Pound, no! Those are my...my 'privates'!" she exclaimed as she realized what he was doing, squirming under him and moving her tail up to cover her modesty as well as she could, given she was pinned beneath her heavier brother.

"S-Sorry!" Pound stammered, before something clicked. "Hey um...sis? Where's your...y'know...?" Pound asked as he noticed she was missing a certain 'something' that he had between his legs, that 'something' he'd distinctly noticed that his mother was missing as well. Sure he'd noticed before that mares and stallions were 'different' between their legs, given nopony regularly wore clothes in the warmer months, but he'd never gotten such a close look under a female's tail before given it was nearly always down. Never had he noticed they were completely missing a sheath, but had two little bumps there instead!

"My...what?"

"Y'know, your...willy? Your sheath? All that's down there are two little bumps and a wrinkle!"

Pumpkin was stunned for a moment, before giving a short laugh. "Silly brother, fillies don't have willies or sheathes!"

Pound was somewhat dumbfounded. "You don't have willies?!"

Pumpkin shook her head twice. "Nope! Mommy told me that mares and fillies have 'fillyhoods' and 'teats', and that we're supposed to keep them...well...private under our tails unless we're using our tails for something or going potty." Pumpkin explained, with Flurry meanwhile starting to develop a blush of her own as she stood at a distance overhearing this, having heard the same thing from her parents. This talk about 'sheathes' was new to her though.

"So, fillies don't have sheathes or the other thingies at all?"

"Wait...what 'other thingies'?"

"I dunno, they're just...like...ball-thingies hanging behind my sheath."

This intrigued Pumpkin. "Can...can I see?"

Now it was Pound's turn to shy away; "I...I dunno. Daddy told me to keep my sheath and thingies hidden under my tail too..."

Curiosity burned at Pumpkin now, "C'mon, it's just a little look..."

Pound persisted. "I...sis, I don't know if I should..."

Pumpkin huffed. "C'mon, you already saw my fillyhood and teats!"

"I...um...I'd like to see what a 'sheath' is too..." A third, much quieter voice came from behind the two debating siblings, both turning to look at the younger Flurry Heart, seeing her shrink away from their combined gaze.

"See, the princess says she wants to see too, so that means you have to! She's royalty!" Pumpkin insisted, now more curious than ever to see her brother's underside more closely.

Flurry was heavily blushing at this point, but didn't respond in the negative.

"B-but she's a lot younger than we are! She shouldn't see...boy parts yet!" Pound said, one last bastion of hope for trying to get out of this situation he suddenly found himself in.

"I...um...I kinda wanna see too...if that's OK?" Flurry said, her blush burning as hot as Pound's was. "You...um...don't have to though."

Obedient to the royal request even given the option, Pound reluctantly rolled off of Pumpkin and onto his back, his hoof accidentally trailing over her teats and making her giggle at the sensation. Pound left his tail down and his hind legs wide open, looking away with a heavy red tint to his face.

Both Pumpkin and Flurry got a little closer to see what was previously hidden to them, and what they themselves lacked. There was a small pouch of skin covered in the thin, cream-colored fur of her brother – what Pumpkin and Flurry figured was his 'sheath' – and beneath that was...what looked like two tiny chicken eggs trapped in a sack too small for them. "What are the egg-thingies for?" Pumpkin asked her brother, who was still looking away.

"I...I don't know..." Pound said, eagerly trying to get this over with, "can I...close my legs now? You looking is starting to make it feel...funny."

"Nuh-uh, not until the princess says you can."

Flurry was still looking between the colt's legs, mesmerized by how different he looked down there than her, "Wow, colts really are a lot different than fillies..."

As the two fillies continued to look at his pride, Pound felt his sheath stirring, knowing the feeling and that his pee-pee would be coming out soon. "Pleeeease..." he asked desperately, but the fillies didn't budge.

"Can I...touch it?"

Pound looked over to Flurry, his eyes wide in a 'please don't' kind of way, but Flurry stepped closer, seemingly emboldened since earlier by her curiosity. "Can I, Pound? I'm asking as a pony, not a princess."

Pound found himself outnumbered, and despite what his father had told him about not showing 'himself' to others, he wondered if that meant only strangers, or to fillies he knew who asked him to as well. "M-maybe we should go to my room to do this? I mean, what if Pinkie gets up and sees us like this...?" Pound asked, stalling.

Both fillies gave a huff, but realized he was right. "Alright, c'mon, let's go." Pumpkin said, with Pound gratefully getting up to his hooves, his tail tucked shyly between his legs, hiding his now-bulging sheath.

As they arrived in the room, the fillies immediately surrounded Pound as soon as the door was closed. "Alright, can we touch it now?" Pumpkin asked, Flurry wordlessly asking the same.

"O-only if I get to touch your 'fillyhoods' too..." Pound more asked than stated, himself curious what the girls felt like down there.

"Alright, fine, but we get to go first," Pumpkin said, "Let's go to the bed so you can lie on your back and we can lay too." The two fillies were hesitant at the idea of the colt looking between their legs, but Pound asked to touch them in kind, so that meant he was at least kind-of interested in the trade.

As they lay down on the bed, Pound flanked on either side by a filly, Flurry noticed something new as she looked between the colt's legs.

"Something's poking out of his sheath now!" Flurry said in some surprise, seeing a bulb-like thing coming out of the top part.

"Cool!" Pumpkin responded.

"That's, um...that's the top part of my pee-pee..." Pound said just above a whisper, his cheeks a deep red even through his fur. Slowly, he was growing more bold now and less reluctant, feeling proud of showing these fillies this part of his body for some reason.

"So, can we touch that too?" Pumpkin asked, nothing if not shameless.

Pound hesitated, remembering how it had felt the previous day when he'd touched himself there. How sensitive it was, and how good it had felt. "O-OK, just...be gentle. Everything down there is really sensitive, especially the ball-things." Pound said, knowing he wasn't getting out of this. On some level, he didn't want to anymore.

Slowly, Pumpkin moved a hoof to touch his exposed sheath, while Flurry's hoof seeked his sack. Pound shivered a bit as the hooves made contact with his colt parts, a tingle of the same sensation he'd gotten the previous night going through him.

"It's...really warm..." Pumpkin said, "...and his colthood is kinda...hard but squishy...?"

"Y-yeah... his egg-thingies feel the same. Really warm, smooth and kinda hard." Flurry responded.

Meanwhile, Pound felt like a museum exhibit. "OK, are you done now?" Pound asked, but heard a gasp from Flurry.

"I-It's growing!" Flurry said, and indeed more of his colthood was involuntarily slithering out in response to the stimulation of the two fillies touching him, as well as all of the visual attention it was getting. Feeling his sister's hoof moving up from his sheath to his actual member, Pound squirmed at the contact, a stronger tingle of sensation going through him at the contact on his sensitive tip.

"It's all pink, and the top part is really thick and looks like it has a ring around the top part..." Pumpkin noted, suddenly smelling a certain scent. It was distinctly Pound's unique scent, but...something else too. Something bolder that she really liked the smell of, and as she smelled it, she felt under her tail starting to feel warmer. Different. Wetter. "What's that...smell? I like it."

Flurry was smelling the scent from Pound too, and feeling much the same way. "M-me too."

"I...don't know. I-Is it my turn now?" Pound squeaked as he felt his willy now limply laying on his belly and lower chest, completely unsheathed and at its full, flaccid length now.

Flurry's hoof had made its way up to Pound's length, Pumpkin's instead taking Flurry's place on his orbs. "His pee-pee also has a ring near the middle." Flurry said, and as she gave the sensitive ring a rub, Pound gasped and his hips pushed upwards involuntarily as a strong tingle went through him, making Flurry panic.

"S-SORRY!" Flurry exclaimed, leaping back with her still somewhat-disproportional wings unfurled on instinct, a very guilty expression on her face.

"Sorry for what?" Pound asked, startled and confused why she'd reacted as she had. It had felt even better than when he'd touched himself, after all!

"I...didn't hurt you?" Flurry asked, cocking her head.

"Well...no. It actually felt kinda...good?" Pound said, questioning if that was even a good way to put how being touched there made him feel. "Yeah, it feels good when either of you touch me down there, but it's...intense, like a good intense, when you touch the top part or ring in the middle."

Puzzled, but nodding, Flurry remained at a distance. "M-maybe it should be his turn to look and touch now?" Flurry asked, getting a small huff from Pumpkin.

"Fine..." Pumpkin responded, but was feeling nervous now that she had to return the favor. She, for some reason, really liked Pound's pee-pee and wanted to stay near it. Rolling over before her brother, Pumpkin laid on her back, her tail moving to the side and displaying everything to Pound. Flurry followed her lead and did the same, though even more reluctantly.

Pound saw that his sister's light-yellow lower belly led down to those two small bumps Pound had seen briefly, her 'teats', that were in place of where his sheath and ball-thingies were. Lower, just above her small, round, lightly protruding butthole, was a small slit between two thin...what looked like flaps that pouted at the bottom, them being a deep brown. There was a small amount of clear fluid on them, and as she lay there uncovered, Pound found that her 'other' scent was 'calling' to him more now.

"Y-you, um, you smell really nice too." Pound said, not sure how to respond to the two separate, totally unique feminine scents; Flurry's wasn't as neon-like as his sister's, but was instead like a cool breeze from the sea mixed with freshly-plowed soil, then mixed with the neon smell of a spell being cast, mixed with filly-smell...somehow all at the same time! As he looked over to Flurry, with her looking much the same as Pumpkin down there - except with everything a deep, dark-pink color, a bit smaller, but just as wet - he gently placed a hoof on his sister's fillyhood. As he made contact, he felt that it was warm, soft, yet just a bit firm under the surface. He also found that it felt slightly wet as well.

Pumpkin softly gasped as she felt a tingle of sensation go through her as her brother touched her fillyhood, her hips shifting upwards a bit and extending that feeling as her parts ground against his hoof once. "I-It feels kinda...weird when you t-touch it...but it feels nice." Pumpkin said, though she wasn't objecting. It actually felt pretty good.

"Y-yeah, it feels weird, but...kinda good too." Flurry chimed in, feeling much the same way as Pumpkin was now as Pound's hoof touched her fillyhood for comparison. Again, it felt the same, just smaller.

"You have these...um...flap-thingies and a bump down here, and it's kinda wet...b-but it's not pee. It smells...nice, and it's...slippery?" Pound said, before moving one of the slick petals aside and seeing something more down there; "Woah! It looks like you have a...it's like a hole down here!"

"A hole? Not pee?" Flurry asked, giving a quiet grunt as more tingles went through her as she felt Pound manipulating her fillyhood as well. It felt rather nice.

"Yeah, you both have it! Wait...there's two holes between your fillyhood flaps, but one's a lot bigger than the other...and it looks even wetter inside!" Pound said as he spread his sister's vaginal entrance open just slightly, then something connected; "This must be where Daddy's pee-pee went when he was hugging Mommy...!"

"Wait, what?"

"Well..." Pound started, then went on to briefly summarize what he'd seen the previous night; his father atop his mom, them hugging strangely, Carrot's pee-pee going between Cup's legs and seemingly into this wet hole, his pee-pee and ball-things throbbing and a splashing sound coming from between their legs, and finally the white milk-like stuff that came out of his mother when they were done, with them talking about 'foals' and her being 'in heat' the whole time.

Pumpkin's expression was one of curiosity, while Flurry's was more reserved and reticent. "That's so weird! Why would they do that...and what does it have to do with foals or being hot?"

Pound shrugged. "I dunno, but when I was watching there was this really strong scent in their room and it made my colthood act all funny and come out of its sheath then get...hard. Then I went to my room after, rubbed my hard colthood, then the tip got all big and swollen, but it didn't hurt; it felt really good, and the same kind of sticky colt-milk stuff came out. The same stuff like Daddy must have put inside of Mommy!"

Both the fillies made a face. "Eeeew!" Pumpkin said, making Pound shrink back a bit, but Flurry looked just as curious as ever. Maybe even more so.

"I...um...I think I saw my Mommy and Daddy doing something like that, but my Mommy was on top of my Daddy and they weren't hugging...just his 'colthood' was going in mommy's 'fillyhood' while she...kind-of bounced on him, and she was going up and down?" Flurry offered, not even sure of it was the same thing.

Both twins looked intrigued, but Pound simply shook his head to snap out of it.

"There, now you know all about colt sheathes and ball-things, and me about filly parts and 'teats'. Are we done now?" Pound asked, but Flurry shook her head. After all, there was always a better way of understanding something, plus he smelled really good to her...and her curiosity overtook her despite her initial repugnance at the idea of 'colt-milk'.

"I wanna...get a special hug from you, like your mommy and daddy did. I want you to put your colt-milk in my tummy."
