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.
