A young Pound Cake happens to see his parents doing something, something weird and seemingly naughty. When his body reacts in an equally weird way, he explores his body...and finds the pleasure he can give himself.

As he later finds the differences between a colt and filly while playing, he confronts his twin sister Pumpkin Cake and their visiting friend Princess Flurry Heart with it. When they figure out their differences and are told of Pound's earlier experience, wanting to learn about it through exploration, Flurry decides maybe it would be more practical to learn about it first hoof.

An Exploration of Fillies and Colt

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."

'Special-Hugging' the Princess

Pound was stunned silent, with Pumpkin's face that of a filly finding out what their Hearthswarming present was early. Before Pound could protest, Pumpkin interjected. "The princess said she wanted it, you have to do it!" Pumpkin said, with Pound still flabbergasted at how a simple game of tag could turn into this!

"Bu-buh..." Pound semi-interjected, but saw as Flurry lay on the pillow on her back, making herself like Pound had described seeing his mother under his father – her croup on the edge, her tail out of the way and displaying herself entirely to him – Pound's body knew exactly what this was. As he saw that little nub-thing peak out of her slit, he suddenly felt the urge to climb on something and start moving his hips again, and he understood what that urge was now as he saw Flurry before him; it was so he could climb on her like his Daddy had his Mommy!

"I...I wanna try that special hug. It felt so good when you were touching me with your hoof, and...you said your parents were really happy when your daddy put his...thingy...into your mommy's thingy and put his milk inside her, so...can you put yours in mine?" Flurry asked, her pink cheeks nearly a deep red now with as hard as she was blushing. As she thought about Pound climbing on her, she felt something moving in and out of her fillyhood, though it wasn't like she was peeing. It was like her fillyhood itself was moving in a way, muscles she'd never used before or known existed moving now to make it so.

<I'm asking him to put his willy in me and my filly parts are moving!>

Pound wasn't sure why, but seeing Flurry laying on the bed like that on her back, showing her fillyhood to him and it moving and a new, nub-thing poking out at him like that, awoke something in him. The same thing that was roused the previous night and by Pumpkin's fillyhood's scent, but this blew all that out of the water. He wanted, needed, to climb on her and move his hips, just like his Dad had done to his Mom.

"I...I dunno."

"Do it Pound. Do the hug with her!"

"Please?" Flurry asked, with her nub-thing peeking out at him again and again.

That did it. Finally, the overstimulated Pound climbed onto the side of his child-height bed, now looming over the smaller Flurry, his chest meeting hers as he climbed over her. He blinked as he found himself like this, having done it beyond his conscious control it would seem, as she'd shown him her nub-thing again and again, him really loving it when she did that for some reason. It felt like she was...asking him to climb on her.

"Um...Pound...?" Flurry asked, starting to get second thoughts about this as she felt how heavily he weighed on her, as well as nervous about not knowing what to expect.

Pumpkin had meanwhile gotten off the bed and gone around behind them, getting a good look between their legs as Pound's own tail flagged up and out of the way, unintentionally showing his sister his 'assets' in full and Flurry's alongside.

"P-Pound? Maybe...we shouldn't..." Flurry tried to say, but she instead gave a quiet gasp as she felt Pound's hips shifting against her now, feeling his long, hard colt-thing scraping against her belly, nudging one of her small, immature, nub-like teats. A burst of the same kind of sensation as when he rubbed her fillyhood rolled through her now, making her shudder a little under him as he pulled his hips back and adjusted his aim.

"Down a little Pound! Your thing's almost touching her fillyhood!" Pumpkin called up, her nose virtually touching his member as she looked closely at the action.

Following his sister's guidance, Pound lowered his hips...but a bit too much. He felt a hard, round, warm form on his willy's head now, trying to push in on instinct to the warmth, but was shaken out of his state by a quiet whimper from Flurry.

"P-Pound...that kinda hurts...not there," Flurry whimpered out, shifting her own hips downwards to guide his hardness away from her butthole, instead trying to find her fillyhood with it, "Higher."

After another few thrusts hitting her belly then sensitive teat again, Pound finally found something wet, warm, and much looser than what it'd touched before, against his head. Without thinking, running purely on what felt right to him, Pound slammed his hips forward, engulfing his colthood inside of that warmth.

Flurry cried out in pain, feeling a sudden uncomfortable, intense stretching inside of her lower belly. She felt like something inside of her tore, a burning, stinging pain radiating through her after it did. "O-OW! GE-GET IT OUT!!!" Flurry exclaimed in panic, trying to get away from what had hurt her on reflex, but being pinned down under the heavier Pound, she was forced to keep it inside her as he held her down on instinct. Her survival instincts started to kick in, her horn starting to light as though she were going to force Pound off of her with magic, but dimmed again as another instinct kicked in. One that told her that this was a good thing despite the pain, to bear with it and she would be OK. So she did.

"POUND! WHAT DID YOU DO TO HER?! I THOUGHT YOU SAID THIS WAS SUPPOSED TO FEEL GOOD! POUND, SHE'S BLEEDING!" Pumpkin squealed out, equally as horrified and panicked as Flurry was as she heard Flurry cry out in pain, seeing some blood coming from her brother's and her union between their legs, his 'colthood' half inside her 'fillyhood' now.

Pound, meanwhile, was oblivious to the commotion going on around him, oblivious to Pumpkin trying feebly to pull the stronger colt off of Flurry. He was simply enraptured by the feeling of warmth and wetness surrounding his colthood for the first time, pulses of strong sensation going through him with each squeeze of her extremely tight passage spasming on him, her body struggling to adjust to the substantial girth spreading her immature passage so sharply. He felt as her insides seemingly form-fitted and gently rippled over his length, a small inner ring just past her entrance squeezing him tightly, as though it were tightly masturbating him inside of her. A thick bulge inside of Flurry pressed against his own belly too, with him realizing later that his willy was so large inside of her that it was causing a significant stretching in her, his girth causing her belly to slightly distend to accommodate it.

This felt right to Pound. This is what his colthood had wanted the previous night, not his hooves. He'd needed to be between a female's legs, in her fillyhood. It felt so good to put his colt parts in her tight, squeezing filly parts, like it was supposed to be there all the time.

As Flurry calmed down after a good number of seconds of being pinned under and filled up by the half-hilted male, her body started to adjust to being spread. When she tried relaxing her newly-discovered 'down there' muscles a bit, she found it helped a lot, with her then finding that it wasn't hurting as much anymore. "P-Pound?" she asked, confused, as she felt another sensation slowly replacing the pain within thirty seconds of him penetrating her. It started faint at first, but eventually it grew stronger with each twitch from Pound's colthood in her, until it felt like a gentle, happy glowing feeling in her belly, right where Pound had put his pee-pee. It felt...good, a stark contrast to the pain she'd been through.

Finally Pound recovered his senses, feeling Pumpkin still fruitlessly pulling on his loins with both forehooves and her weaker magic, trying to pull him off of Flurry it would seem, and actually gaining some ground. "H-Huh? What're you doing sis?" Pound asked, still in a daze as he felt his pee-pee being pulled out of that perfect-feeling warmth surrounding and occasionally squeezing his top part, resisting by trying to push back in on instinct.

"Get off of her! Your pee-pee's hurting her and making her fillyhood bleed!" Pumpkin half-shouted, not noticing how calm the other two foals were now.

Pound's eyes widened as he looked down to Flurry, expecting to see her in agony, but instead saw her eyes closed, a small smile on her face. Pound was completely confused. "Uh...sis...Flurry's smiling." Pound replied, quirking an eyebrow as he looked back to the panic-stricken filly.

Flurry was indeed smiling as she felt pain completely replaced by that warm feeling, the once-painful stretching feeling very welcoming now. Oddly, it felt like Pound's colthood was hugging her from the inside. "I...wh-what's that...feeling...?" Flurry asked, her thoughts hazy and her heart thudding against Pound's chest, "...it hurt a lot at first but now it...feels...really nice...? How are you so...deep in me?"

"I'm sorry for hurting you, but I only put my pee-pee in your hole, like our parents did," Pound said, relieved that she wasn't hurting anymore like Pumpkin had said she was, "But I...I feel the same. I think you have a kind of...tunnel in you, between your legs?" he responded simply, not knowing himself.

"I-It's like your pee-pee is...kinda...opening me...and, like, hugging me inside? It doesn't hurt now...just feels all warm and...nice..."

"Mmhm. It feels like your fillyhood is hugging me too, but on my colthood..."

Pumpkin was beyond confused; Pound going inside her had really hurt Flurry and made her bleed when he'd put it in at first, but now it felt really good and she liked it? "Huh?" Pumpkin asked, "M-Maybe you should take it out of her so we can see what happened?"

"I...I don't want him to..." Flurry responded instantly, whining a little as she did when asked to do something she didn't want to do, her smaller rear hooves squeezing against his sides. It felt...right to have Pound's thing deep in her filly-thing like this, and she didn't want him to stop having it in her.

"I...I wanna stay in her too. It feels really warm and tight and..."

"Right."

"Right."

Both Pound and Flurry said it at the same time, sharing a quiet chuckle as they did.

"Are you OK now, Flurry?"

"Mmhm. S'nice..."

"Can I try moving my hips like Daddy was? I...I really want to..."

"I...I think so...yeah, go ahead."

Flurry really wanted Pound to start moving in her again, something deep inside her telling her that being spread open by a colt like this was the right thing to do. Pound slowly pulled his hips back in response, before slamming them forward again hard on his breeding instinct, getting a forced 'UH!' from Flurry as he did, that hurting a little for her.

"N-not so...hard...try...slow..."

"OK..."

This time Pound slid out slowly, and slid in just as slowly, jerkily, it taking all of his willpower to not just ram his hips in and out of her rapidly like his dad had with his mom. Each time he slid in or out, intense tingles would roll through his willy and up his back, making him want to do it again, and again. The feeling of Flurry's warmth surrounding him every time made him start to give quiet, cute grunts with each slide in.

"T-That's p-peeeeeerfect..." Flurry whimpered out, the warm 'hugging' feeling inside of her growing again every time he was inside her, with each slide feeling like it ended further and further up her belly, until finally she and Pound felt his tip hit something and stop with a jolt, his member stopping just before his medial ring.

"H-huh?" Pound stammered, unable to manage much more given his clouded mind, feeling his tip hitting something deep inside of her that stopped him from going deeper.

"I...I think you found a...stop inside me?" Flurry suggested. It had hurt a tiny bit when he'd hit that 'stop', but Flurry hadn't really minded. Something about him touching that deep in her felt...right.

"B-but Daddy's was all the way inside Mommy...maybe...fillies are different than mares in there?"

"M-M-Maybe...j-just keep going like before, but don't go deeper...I guess? It feels...really good when you're moving deep in me like that...mmm...and your tip is getting bigger~...opening up my filly parts more!"

"It feels...really great for me too. I...You feel lots tighter now around my tip! S-something's coming soon...m-my colt-milk, I think..."

Pumpkin remained on the floor watching the action from behind, using her magic and hoof to spread her own fillyhood apart gently, gasping at the sensations of it even spreading a little, before it'd started hurting and she'd stopped pressing deeper. As she watched as Pound's motions continued to slowly rock in and out of Flurry, she kept slowly rubbing herself on reflex, feeling her own slit pulsing against her hoof like she'd seen Flurry's doing even now, her little nub peeking out and 'kissing' her hoof...before something suddenly changed.

"Alright," Flurry said after some minutes of Pound rocking into her, nearly drooling at the feelings; "please stop and take it out Pound. I wanna try this the way my mommy and daddy did it now, with me on top!" Flurry said, though with some reluctance to losing that filling, lovely warmth inside of her again. Her own sensations were just starting to build...

Pound very reluctantly slowed then stopped his instinctive humps, then even more reluctantly pulled out of those warm confines he'd quickly learned to love, it being kinda hard to remove his flare given how swollen it had gotten towards the end. He was feeling like he was almost ready to do the 'colt-milk' thing like he'd done the previous day, but forced to stop before he could. "Filly insides are awesome!" Pound exclaimed, getting a smile from Flurry.

"Mmm...so are boy parts...!" Flurry responded, "Here, you lay on the bed like I said Daddy did, then I'll climb over you and put your thingy in me like Mommy did Daddy's." Flurry explained, then moved Pound to lay on the bed the same way she'd described Shining Armor and Cadence laying, Flurry then straddling him. Soon she felt his flare prodding around her thighs, before quickly hitting home, his colthood once more pressed to her fillyhood as she half-stood over him.

"Yes...boy parts are awesome! Bro, your thingy's way cool too! I love your pee-pee!" Pumpkin added as she shifted positions as well, a few drips of her filly-juice drooling out of her as she stood and climbed onto the bed, laying on her back, leaning against the bedframe and spreading her hind legs so she could watch the young mare and stallion already laying on the bed through them. She also started unintentionally giving Pound quite a show as she shamelessly started rubbing between her slit as he watched her do it; seeing his sister touching herself because of him made Pound's cheeks flush pink.

In position, after some adjusting by both parties, Flurry placed her hooves onto Pound's chest for balance, Pound reciprocating with his hooves softly gripping her around the haunches and croup, before she slowly eased Pound's colt-hood into herself once more.

~ ~ ~

Pound's moaned out as the new sensations rocked through his body, Flurry's flaps sliding down him instead of him into her, his flare popping past them and inside of her filly-parts again. A warm, insistent, squeezing inside-hug on his pee-pee greeted him as he passed deeper, feeling Flurry's insides gripping on him, with that feeling being so instinctively perfect to the young stallion. "Y-Your...part's squeezing mine...is...that you doing that?" he asked, confused at the new feelings her being on top added.

"I...I don't know...this feels..." Flurry commented, only giving a hard shudder atop him in conclusion. As she rose her hips, as she'd observed her mother Cadence do when she and her father Shining Armor had done this together, she then quickly dropped on him, finding that it didn't hurt this time, instead feeling amazing. "T-That..." Flurry muttered out, before repeating that drop just as hard, again and again.

Pound's tongue slid out of his mouth as he started panting, the feeling of her inside place on his willy so amazingly awesome he never wanted it to stop. When he, however, started rocking his hips up to meet her drops, impeding her at first before getting into her rhythm, he found it felt even more amazing than when he held still and let her do everything. Each hump up made her drop feel more...validated somehow; as though he was confirming that, yes, they were doing this right now.

Flurry, on the other hoof, welcomed the feeling of Pound living up to his name, pounding up into her midway of each drop, adding force to each stop and making her lower lips slap wetly against his ring. Both foals were speechless, their bodies simply running on their hard-wired instinct to reproduce, every fiber of their beings screaming this was right; that this was what sexually-mature fillies and colts were supposed to do together this time of year, in order to assure that there would be more fillies and colts born next year.

While it used to hurt when Pound hit that deepest portion of her, Flurry found that now it felt more comfortable than a hug on a cold winter day. Each time he hit it made the feelings spike a little more for Flurry, the squishing, schlicking sounds of their breeding grew louder as their pace increased. She felt her little bump thingy poking out rapidly now, feeling the wetness her marehood was releasing to help him slide that much easier.

Seeing her teats poking out more in her arousal, Pound started to softly rub them with a hoof, earning a quiet moan from Flurry. He also quickly felt the bulge he was leaving in her as his stallionhood spread her wide, making him shudder as he remembered it was indeed him who was doing that to her, and while he wasn't sure why, he LOVED that.

Meanwhile, while Flurry was riding her colt brother like the stallion he now was, Pumpkin was using both hooves to stimulate her fillyhood, watching Pound and Flurry doing this making the urge to touch herself 'down there' impossible to resist. She felt her own pleasure rising up, though her hooves weren't enough. Soon she lit her horn and started rubbing with her magic instead, letting a quiet squeal at the intense, tingling sensations that manipulation spell added.

Flurry meanwhile trailed a hoof down to touch where Pound and she met and separated so intimately, feeling the same bulge he had, and for some reason that made her shudder hard at the fact that he was in her filly-place, stretching her so far, making her feel good on a very deep level. Like she was supposed to have him stretching her open so much in there, and more.

This went on for a minute or so, Pound and Flurry unsteadily rocking against each other, Flurry grinding against his thick medial ring when he was deep inside her and finding that it felt absolutely indescribable when her pleasure nub came out and hit it. Flurry felt a kind of pressure and heat building where Pound's thick tip was, completely oblivious to everything else except that growing sensation and Pound's member in her belly. It didn't hurt though, quite the opposite. Her body was screaming at her that this was the best thing ever, to keep rocking her hips like she was. She only too eagerly did.

Pound felt that same pressure building in his pelvis as he had the previous night when he'd 'milked', his hips starting to lose the rhythm as he felt the urge, the overwhelming need, to get as deep inside of Flurry as he could and stay there, yet not knowing why. He felt his tip getting bigger again, the sensations in his groin rapidly increasing alongside his pulses growing more rapid and rhythmic.

"I'm...I'm gonna milk...s-soon..." Pound muttered, struggling to stay inside Flurry's hole as she increased her pace again. Needing to stay inside of her, he yanked down hard with his hooves around her croup and hips, forcing her to keep his member as deep as she could as his instincts demanded he do, them telling him something very important was about to happen, and he needed to stay as far as possible inside her when it did.

"F-Flurry, it feels like I need to...p-peeeee!" Pound warned, though he knew somehow that it wouldn't be pee coming from him. He was pretty sure it would be that milk stuff, and he felt he needed to do it inside her for some reason.

Flurry was too far gone and didn't hear Pound's warning, then yelped as she felt herself being yanked down and felt his thingy getting bigger and throbbing very deep inside of her, her passage in turn squeezing rapidly on him in response, the pressure and heat building up even higher for her. "P-Pound, I...I feel..." she stammered out, feeling the pressure and powerful feelings magnifying in her belly as he grew bigger in her and spread her depths more. She'd never felt something so intensely as she was now, her whole body needing to get rid of this pressure, feeling like she was about to explode, and on some level she knew she would, in a sense.

Pumpkin watched from the sidelines as Pound and Flurry reached their penultimate moment, her own sensations starting to accumulate quickly. "W-wow..." she simply muttered as she watched her brother holding Flurry tight to him, seeing the base of his thingy throbbing, the rest deep inside her, his ball-things flexing in time, tail flagged aside to show his sister everything. As the other two cried out simultaneously, Pumpkin rubbed her nub rapidly as it peeked out, that final spike of stimulation sending her rocketing over with them.

Pound felt as his thingy started pulsing hard inside of Flurry against his will, tail slightly flagging with each pump, intense waves of pleasure rolling through him. He felt something shooting out of him and into Flurry with each throb, his hips rocking against her with each thick ejaculation. Pound’s tip was pressed taut against what he didn't know was her cervix, sending his virile load directly into her small, immature womb as his thick flare let nothing past.

As Flurry felt something very thick, warm, and sticky shooting and pooling deep into her belly as Pound's penis throbbed inside of her, for some reason that was the best thing she'd ever felt in her life – followed instantly by the new best thing she'd felt in her entire life. Flurry cried out the same time as Pound did as she felt her insides start to squeeze Pound hard from base to swollen tip, feeling intimately each throb it made inside of her, each shot of cum he gushed deeply into her, all topped off by intense tingles rolling through her. She couldn't think, could hardly breathe, her whole focus being on keeping that stallionhood deep inside her marehood, pumping that warmth she really liked into her belly, making it swell up a bit.

Flurry felt something oozing from her, something thick gushing out of her and onto the colt beneath her. Releasing her own off-white mare-cum to mix with Pound's semen, rolling down his sides while her bump blinked rapidly against his ring and only added to the sensations that much more. As she remembered something else her parents did when they were doing this, Flurry leaned over and met her lips with Pound's, giving the young stallion the first, sloppy, kiss of his life.

Pound felt a wetness released on his crotch and pee-pee, passively wondering if Flurry was peeing on him, but that thought was instantly washed away with another squirt of his seed deep within her and the accompanying surge of ecstasy. As he felt Flurry's lips meet his, he was initially very surprised, but instead moaned into her muzzle as he pressed back, finding that her kissing him was only enhancing the sensations already rolling through him.

Pumpkin meanwhile felt her own first orgasm rocking through her, her hoof digging at her bump that was constantly 'blinking' now. She felt her whole hoof getting soaked with her off-white-tinted fluids and some even squirting past to get on her brother's cheek as she jerked her hips rapidly against it on instinct, rubbing along her whole slit with the frog of her hoof. The feeling was so intense, but her body felt it was missing something, making her wonder if it could feel even better than this. Her fillyhood felt so empty for some reason, and she couldn't understand why...until she looked over at the other two foals and again saw Pound's thingy pulsing deep inside of Flurry. Maybe...

As the trio slowly came off their highs, none knowing just what had happened, Flurry collapsed onto Pound, laying atop him now as the three rested, his thingy still all big inside of her and the building heat and pressure she’d been feeling before dissipated. Eventually Pound's member softened and slid out of Flurry with a quiet 'schlick', both moaning as they felt it. "W-What was...that?" Flurry asked, a little scared and confused at what she'd just felt, "It felt...weird but good. Like my...insides were really hugging you? Then I was tingly all over and...I couldn't stop it and...then it felt like I...peed on you?"

"Yeah...that's what it feels like when my milk comes out, except it's more like...my pee-pee pulses then milk comes out. I...I don't smell pee either, just more of that...clear stuff you made earlier? But it smells different."

"Oh, it's not pee? Phew. Was that...your 'milk' I felt...going in me...?"

"I think so..."

"Wow...it feels really good and warm inside my tummy now."

"Yeah, felt really good when I put it there too..."

Pumpkin was meanwhile watching from behind as her brother's willy popped out of Flurry, watching the milky mess go out of her and onto Pound's ball-things and tail, joining Flurry's 'fluids that weren't pee'. "Wow...it really does look like milk, except it's a lot thicker looking...and smells different." she muttered, then she got something in her mind, "Hey bro, do you think you could do that to m—"

"POUND, PUMPKIN, FLURRY, IT'S TIME FOR LUNCH! GET YOUR HOOVES CLEANED AND COME EAT!" Pinkie's cheery voice called up, startling the trio.

"C'mon, let's go take a bath really quick. We can't go down there like this..." Pound said, gently rolling Flurry off of him as he stood, smelling like two satisfied mares.

"But Pound... I wanted..." Pumpkin said, unable to hide her disappointment.

"Don't worry sis, we can always do this more later. Next time, you can go first!"

Both filly and young mare couldn't hide their enthusiasm at that promise.

Pound Cake was awakened in the middle of the night to the sounds of soft, intense whispers and quiet whinnies and whickers coming from another room. It sounded like his parents making those sounds, but they never had sounded like that before.

"Hmm...?" Pound muttered and, curiosity getting the better of the young Pegasus colt, he rubbed his deep-brown eyes with a cream-brown hoof and got up. He stretched his small wings as he walked, getting up and walking across the hall to his parents' room where the noises were coming from, then peeking inside.

Given it was a warm Spring night, neither of his parents were covered as Pound looked in to see his father Carrot Cake on top of Cup Cake, his mother, in the light of the full moon. She was laying on her back, Carrot laying on top of her hugging her in a funny way which pressed his yellow-coated chest to hers of light blue, and his hips to hers too. Even more strangely, he pulled away and then put their hips together again, then kept doing that.

<What're they doing...is Daddy hugging Mommy? Why's he hugging her like that, and why are his hips...moving so funny?> Pound wondered, watching on. Pound continued to watch his father's hips shifting back only to thrust forward and wetly slap against his mother's. He saw his father's pink-and-black willy looking stiff and wet for some reason, with the moans and quiet cries making them sound like they were in pain, but the whispered encouragements from his mother proved differently.

"Please...I need you more. Harder! I'm in heat, breed me like I am!" Cup Cake harshly whispered out, and Carrot's motions seemed to grow faster as he nodded, Cup barely restraining a moan it would seem.

Pound also noticed an odd, almost suffocatingly strong musky-earthy scent very prevalent in the room, making Pound feel a little light-headed alongside the confusion of what he was observing. He wanted to keep watching for some reason, and it made his colthood feel funny and tingly. He'd never felt like this before and was somewhat scared, but something deep inside him told him it was OK to feel this way. That feeling this way was actually a good thing. His hips were mimicking the motions his father was making on their own, and Pound was simply letting them.

"Oh b-buck I'm so close...Oh Celestia, I can feel you f-flaring in me! So biiiig!" Cup Cake said in a high-pitched voice Pound had never heard from her before, her head pressed back hard into the pillow.

"M-Me too Honeybun! Inside or out?!" Carrot responded, his voice just as strained.

"IN! CUM INSIDE ME~!" Cup instantly answered, and Carrot slammed home once more with a wet smack instead of pulling out despite feeling himself getting very close, his flare swelling up thick in his wife; his tip plugging her passage to naturally assure his seed went deep inside of her instead of simply leaking out, increasing her chance of getting pregnant with his foal.

Both adults tensed up shortly after Pound started watching, his father's hips' movements getting much shorter and faster, both giving an especially deep, shared moan as they met their lips together in a kiss. Pound saw as his father stopped with his crotch flush with his mother's, his tail flagging up and revealing all to their unknown voyeur as his orgasm started.

Pound saw from the straight-on view that he had from the doorway that his daddy's willy was all stiff and was going under his mother's tail into...a pink-insided something between her legs. What little of the length left outside was rapidly twitching, as well as the funny yellow-furred ball-like things hanging underneath his pee-pee pulsing at the same time too. Only panting and quiet wet smacks that came from his parents' kissing was audible in the room at that point, as well as another quiet, wet splashing sound Pound couldn't identify.

Meanwhile, Pound felt a weird new heaviness between his stifles, his wings unfurled and erect above him, his cheeks flushed and feeling very warm as he was undoubtedly blushing heavily. He was panting as though he'd run around a lot, his hips still shifting, feeling hot and...strange. Deeply dissatisfied for some reason.

As Carrot pulled out of his wife after nearly a full minute of doing the pulsing thing and then keeping his pee-pee between her legs, his tip looked really big, wet, and swollen, and a weird white fluid that looked like kind-of like milk came out of her blue-lipped, pink-inside 'thing', as well as being on his dad's willy. As they relaxed, the mare and stallion lay down and cuddled up, kissing once more.

"I love you so much Honeybun..." Carrot cooed, sneaking another soft kiss.

"I love you too." Cup responded, petting her lightly-distended belly, "Holy hay you filled me up good..." She then sighed at the implications of being seeded in her heat, knowing she'd get knocked up again if she didn't do something about it; "I'll have to get something tomorrow to make sure we don't have another foal. Don't need another one just yet, with the twins just getting older and more independent...letting us do this more often..." Cup said, nuzzling into her husband's soft fur. Already though she imagined she could feel his virile seed fertilizing her egg or eggs, images of her belly swollen with his foal or foals again flashing through her mind...though she blamed that all on her estrus hormones, she knew it wasn't entirely true.

"Would having another beautiful foal or two really be the worst thing though...?" Carrot asked seriously, softly rubbing his wife's 'thingy', smearing the white 'milk' all over it, "...I kinda miss the clops of tiny hooves around the house."

"Mmm, we'll talk about it tomorrow with clear heads, OK?" Cup replied, realizing then just how much she too missed little foals running around as well, and everything that came with it. "Thank you so much for ending my heat though, at the very least." Cup Cake however had already decided not to get the herbal contraceptive 'oops' pills after all, her life mate having all but agreed already. Decided to let her husband's seed take root in her womb once more and give her a foal after hearing how he too wanted another child or two, already knowing her husband's likely response when they talked about it the next day. That he'd say yes.

"I promise, it was my pleasure honeybun."

One more kiss and chuckle from Cup, and soon after Pound could see they were now sleeping in an embrace.

Pound was now baffled and confused at what he'd just observed, as well as how weird he was feeling now because of it. Pound thought, <Why was Daddy's pee-pee all hard like that? What was that white stuff that came out of Mommy and...was it inside Mommy? Ew!Wh-why were they doing that?>

Pound slowly stumbled to his room in his pheromone-induced stupor as he thought, feeling something slapping along his inner stifles as he did. As he entered his room and quietly closed the door, he looked down to see what that heavy-feeling thing slapping his thighs as he'd walked was. As he looked, he saw that it was his colthood that was out of its sheath like when he was peeing, but now it looked kind-of swollen. As he looked more, something clicked: he realized that his pee-pee looked just like his father's had when he was putting it into his mother's 'thingy'.

At that epiphany, instead of getting his parents for his swelling, he instead gave it a rub on some instinctive impulse. he wondered as he felt it twitch under his hoof and seemingly grow harder, a strange current rolling through him, his hips shifting upwards. He rubbed his penis again, rewarded with another pulse of that strong, but really nice tingly feeling. Then he gave it another, full-length rub, his hips bucking harder this time as he rubbed over his medial ring, his whole colthood at full erection; a raging five inches. Not bad for his age.

For some reason he couldn't figure out, rubbing his willy when it was swollen like this felt really good, compelling him to wrap his hooves around his colt-sized length and start to stroke it more with both hooves, quiet whimpers coming from him involuntarily.

Pound thought as he kept rubbing, the sensations getting more intense, as well as the throbs coming from his colthood. His wings unfurled at the sensation and laid stiffly beside him on the bed, a testament to just how good he was making himself feel.

The weird musky-earthy scent still in his muzzle, Pound upped his actions more, stroking himself much more firmly as something slippery started dribbling from his tip. His hips started to shift up with each downward stroke, his back hooves kicking and digging into the mattress in the intensity.

After only a minute or so of very quickly stroking himself, Pound felt his very tip starting to get really big, triple what it usually was, and even more sensitive, but he couldn't understand in his daze why it was like that. He couldn't understand why his hips were humping sharply now, his hooves matching pace, everything coming to a climax.

As Pound thrust up one more time, he let out a quiet whimper and sealed his eyes shut tight as the sensations all came to a head, his hips hiking up completely off the bed and his back arching up as he felt something in his pelvis snap and his ball-things pull tight to his body.

As he tensed up, he was utterly confused at the new, foreign, but intense sensations rushing through him, feeling a sort of pulsing sensation coming from his penis as he kept his hips rocking sharply, unable to move or think as he felt something pulsing deep in his pelvis, doing this weird throbbing thing with his member that he couldn't stop – then something shot out of him as he gave a quiet 'aah~', then another, and another shot, with each thrust of his hips painting his belly and even up to his chest and muzzle with his powerful first ejaculation. Pound was unable to think or do anything other than keep rocking his hips and squirting like that, intense tingles going through his whole body as he did, emitting quiet squeaks as well with each pulse.

As the intense sensations finally died off some seconds later, his whole body tingling and his colthood's tip still really big, the whole thing feeling really sensitive now as he held it firmly, Pound lay on his back panting, his deflating member still held between his hooves before slowly retreating into his sheath again. "What...was that?" Pound quietly asked himself aloud, feeling a wetness on his belly, "Oh ew, no! Did I...pee on myself?!"

Looking down to find something on his belly, Pound quickly found that the thick fluid coating his underbarrel looked nothing like pee, being off-white and thicker instead of watery; some kind of...sticky goo. "This...isn't pee...what is it?" he asked as he saw the stuff was on his hoof as well, pressing his hooves together and watching it string between them whilst being still sticky. As he gave it a curious sniff, he found it definitely smelled like him, but...something else too. It was confusing, but he could only find himself more fascinated by the moment. "Did this...come from inside of me?" he questioned himself; he guessed as much but he truly had no idea. All he knew was that what he'd just done was probably the best he'd ever felt before, and this goo...kind-of looked like what his daddy had put in his mommy. "Is this some kind of...colt-milk? I thought only mommy ponies could make milk...and why were they talking about foals when he put his...goo in her...and she was 'in heat'?"

He was simply too dazed and feeling too good to think clearly anymore. "I-I'll ask mommy or daddy about this in the morning," Pound muttered quietly to himself before, exhausted and enraptured in his afterglow, Pound fell asleep just like that, covered in his first ejaculation; virile seed.
