Making A New Sibling

Two Weeks Later

After the lengthy weekend trip spent up in the Crystal Empire, a lot of time was needed from all three parties following their efforts. By the time Night Light had returned to Canterlot, both Cadance and her husband had lost count of how many times he flooded her womb. In addition, Shining still had to keep his cage on for the duration of the waiting time. Cadance spent everyday checking herself with pregnancy tests, all while keeping the news hidden from the public. It was fortunate that she was able to carry herself so naturally around the castle, not giving any hints that something could be different. As for her husband though, Shining definitely got some rumors from castle staff regarding his “attitude”.

“Ugh…” Shining hated to admit it, but the two weeks he spent in chastity were some of the most arduous moments of frustration in his life. Cadance tried her best to help him out when they were alone, but she could only do so much while keeping him from ejaculating just yet. Shining tried his best to maintain his composure, but he certainly felt a little crankier due to his ever-straining erection. Not to mention, the longer he spent by himself following the events of that weekend, the more wary he began to feel about what might happen next.

“Jeeze, when is this day going to eeennndddd…” Shining was walking by himself down the hallway, and needed to pause and drag his hoof down his face. He had spent that whole morning buried in paperwork in his office, and was eager to try and relax in privacy. However, just as he turned the corner to reach the elevator, he gasped in surprise when he saw a familiar face nearby. “What the… D-Dad?!”

“Oh, there you are!” Night Light was conversing with the two Guards posted by the elevator, but quickly turned around with a cheerful smile. Shining ran up to him, and the two shared a deep and platonic hug. Neither of the Guards intervened, and respectfully averted their eyes while the two spoke.

“Dad, what are you doing here? I-I thought we were going to message you first.”

“What are you talking about?” Night Light looked a little confused, and he lit up his horn to pull out an item from his saddlebags. He floated out an envelope that contained his train ticket to the Crystal Empire, as well as a hoof-written note. “I got the note this morning! Didn’t Cadance tell you?”

“Wait, what?” Shining took the note from his Dad’s aura, and read the brief message his wife had sent:

‘Night Light,

Come to the Crystal Empire immediately! I have some great news~

-Cadance’

Shining was stunned with his eyes and muzzle wide-open. Night Light just huffed with a smirk, and he leaned in to whisper discreetly, “Did she not tell you yet?~”

The Prince shook his head, and he made sure the Guards nearby weren’t eavesdropping while keeping his muzzle shut.

“Well, come on then!” Night Light motioned towards the elevator, with both of the Guards stepping aside. “I have a feeling we have some things to discuss privately…”

“Y… Y-Yeah, of course…” Shining was trying not to blush when he lit up his horn, and pressed the button to open the elevator doors. Both stallions entered it to make their ascent, with the older one grinning rather confidently to himself. As for Shining, who still needed a moment to process his feelings, he was grateful for the two to be alone when he breathed out with a strong blush. “Oh, wow… H-Holy crap…”

“Yeah, tell me about it~” Night Light patted his son on the back with a hoof, smiling at him warmly. “Hey, uhhh… you gonna be alright?”

“Yeah, I… I think so…” Shining huffed after that uncertain response, and he quickly shook his head before reiterating, “I-I mean, yes I will. I just… wow…”

“Hmph…” Night Light took a moment to let Shining breathe, and he waited for his son to look back at him before speaking. “Listen, I… I already talked with Velvet about all that happened, and… If it means anything, I’m not planning to do anything else with Cadance anymore.”

Shining nearly gave himself whiplash when he jerked his head and stared at him all wide-eyed. “W-What?”

“What do you mean, ‘What?’” Night Light huffed and kept a cheeky smirk. “I’m still married to your Mother, remember? She may have been alright with Cadance being a surrogate, but neither of us were wanting to go further than that.”

“W-Well yeah, of course…” Shining sighed and nodded without question. Considering how wild things got over the weekend, it was a bit of a relief to see that his Dad hadn’t become a total Dom or Bull in the aftermath. Upon reflection, Shining shook his head with a scoff and muttered to himself, “Well, at least I know I picked the right stallion to try this with.”

“Oh, absolutely!” Night Light chuckled and slapped his son’s back. “C’mon, give your old man some credit! I may have had fun, but I’m perfectly happy with Velvet as the only mare in my life.”

“Well yeah, totally. And the same goes for me and Cadance…” Shining was really happy that the two had that kind of talk so casually. Even though the two had done things no father and son should ever do, Shining could think of several ponies who would’ve taken things WAY further. In a weird way, the whole experience felt strangely wholesome. Or at least… perhaps as wholesome as incestuous cuckolding could get.

When the elevator doors finally reopened, the two entered the vacant hallway which led to the bedroom. Shining paused after the elevator door closed behind them, and he looked over at his Dad to ask, “Hey, uhhhh… before we see Cadance, I gotta ask… What did Mom say?”

Night Light stopped with his muzzle slightly clenched, knowing exactly what his son was referring to. He sighed a little before turning towards him, his expression a little reluctant. “... Well, ummm… For starters, I’m happy to say that Velvet isn’t upset about my errr… other experiences that weekend…”

Shining bit his lip pensively. “You mean… regarding us?”

Night nodded his head before giving an uneasy shrug. “I mean, she wasn’t exactly thrilled to hear what we did, but… Well, it’s not like I could accidentally knock you up or anything. Heh heh~”

Despite that weak joke, the two were left standing awkwardly across from one another. Night Light breathed out through his nostrils and scratched his neck with a hoof. “With that being said though… I-I was actually reminded by your Mother about a… a deal we had when we started dating as teenagers…”

Shining tilted his head, looking slightly puzzled. Night kept his eyes pointed elsewhere as he explained, “You see, neither of us had much experience before meeting each other, so… In order to keep things fresh, we decided to make a small agreement out of mutual respect. Your Mother actually suggested the idea that… If we were to try things with other ponies, it would be preferable if they were of the same sex.”

“W-Wait, what?!”

“Well, yeah! I mean…” Night Light was starting to blush as his smile grew more flustered. “She figured that if I slept with another stallion, that wouldn’t be as bad as sleeping with another mare. Velvet is the only mare for me, and I’m the only stallion for her. But when it comes to gay experiences, well… neither of us can compare one another to that, y’know?”

“Aaaahhhh, I get it…” Even though he looked a little weirded out with that new info, it helped to make Shining nod respectfully. “So basically, you’re allowed to be with guys, and she can be with other mares?”

“Exactly! And… well, uhhh…” After an awkward pause, Night Light shrugged his head and added, “If… If you’re okay with that, then… so am I.” With that, he gave the weakest of smiles to show Shining what he meant beneath the surface.

Shining smiled with a bit of hesitancy as well, and looked away from him rather bashfully. “Heh~ Well, ummm… In that case, let’s hear what Cadance has to tell us first.”

“Good idea.” He pointed over at the still-closed door down the hall in front of them. “Lead the way, your Highness~”

“Y-Yeah, uhh… Sure thing…” As he stepped forward and walked towards the door first, Shining Armor had to prepare himself for whatever was waiting in the bedroom. Night Light was close behind him, grinning wide and eager to hear the good news. As soon as the doors opened, the two entered to see a familiar mare resting on the bed.

“Oh, booooyyyyyssssss~”

Princess Cadance, who had just showered with her fur freshly shampooed and musk-free, was beaming from ear to ear while seated on the bed. Her horn lit up with a bright blue glow, while her aura opened the drawer beside her bed. She giggled when she saw how flustered Shining looked behind his red cheeks. “Hehehehe~ Sorry for waiting until now to reveal it…”

In her magic, a small piece of white plastic was floated across the bed towards the two stallions. She placed the item at the foot of the bed, which turned out to be a brand-new pregnancy test. The father and son gasped at the same time, with Night Light looking absolutely elated by the little red Plus-symbol revealed in the slot. Shining clasped his hooves over his mouth, his eyes bulging at the results in stunned silence.

“I’m PREGNANT!!!~”

“AAAAAHHHHHH!!!~” Night Light cried out excitedly, immediately tearing up with a shaky grin. His hooves were stomping up and down as he hopped around the bedroom, looking as excited as Twilight Sparkle after getting a new book. Shining was still frozen in place, but he was soon tearing up as well; when he finally pulled his hooves down, he was smiling at his wife in pure, non-judgemental bliss.

“I’M HAVING A BABY!!! I’M HAVING ANOTHER BABYYYYYY!!!” Night Light rushed over to the bed, hopping into the mattress so he could give Cadance a strong hug. She was taken aback for a second, but quickly hugged him back with a huge smile. Meanwhile, Night Light was sniffling with tears streaming down his face. “Oh my gosh… Thank you so much! Thankyouthankyouthankyouthankyoooouuuuuuuu!!!”

“It’s the least that we could do for you…” When the two finally pulled away, Cadance was struggling not to cry while smiling at him with so much love in her heart. “... D… Dad~”

Night Light’s heart skipped a beat, and he instantly pulled her in for an even stronger hug. Shining had to look away and wipe his cheeks with a hoof, feeling just as touched by that gesture as his Dad. After that secondary hug, Cadance nuzzled his chest and sighed contentedly. “Aaahhhh…”

Night Light eventually pulled back first, and stepped off the bed to go and get some tissues. Shining floated a tissue box to him with his magic, and watched as his Dad blew into a couple tissues with a loud ‘Honk’ of his sinuses. That noise was enough to make Shining and Cadance giggle, lightening the mood after such a momentous reveal.

“Whoo! Well, uhhh…” Cadance wiped her face with the back of her foreleg, but she remained on the bed while peering back at her husband. “Okay, a deal is a deal! Since I fulfilled my end, you’re free to get out of that cage.”

“Oh, finally!” Shining lurched his head down and sighed in great relief. “Nnnnghhh!! Goddess, you have no idea how badly I need to get out of this stupid thing!”

“I don’t blame you at all for feeling that way.” Cadance turned back to Night Light with a smile. “Alright then! I’ll let you unlock him~”

Shining turned his head, and his relieved smile dropped like a stone when he saw his Dad’s expression. Night Light was standing wide-eyed with a pale look on his face, and he tried his hardest not to bite his lip. “... uhhhh… well, umm… about that…”

Shining’s jaw dropped to the floor. Cadance looked just as shocked when she said, “Wait, did… did you forget to bring the key up here?!”

“Do NOT tell me you left it in Canterlot, Dad!”

Night Light looked between the two, spending a couple seconds in uncomfortable silence. Seeing the horrified looks on both of their faces, he was only able to maintain his expression for a moment before letting out a stifled giggle.

“Hehehehehehe… I’m just kidding!” Night Light quickly revealed a more carefree smile, and he lit up his horn to float out the key from his saddlebags. “Yes, I brought the key. I’m not THAT mean.”

Cadance sighed with a hoof over her chest, and even giggled a little in relief. Unfortunately, Shining still looked a little pissed as he glared at his Dad. “That’s NOT funny!”

“Okay, okay! I’m sorry…” Night Light pointed over to a plush armchair at the corner of the room, which Shining walked towards with a frustrated sigh. The stallion sat himself down in the chair, and blushed with a wince when he opened his legs. His metal chastity cage was still shining brightly against his waist, like a little piece of jewelry trapping his cock. Night Light was shocked to see just how badly his son’s member was bulging through the gaps of the polished metal, and could only imagine how uncomfortable it must’ve been. He winced more apologetically, and he got on his knees before the foot of the chair. “Okay, just a moment…”

Night Light used his magic to float the key in, and he effortlessly slipped it inside of the cage’s lock. With only a quick turn and a click, the device opened up instantly. “Aha! Here we--”

-SMACK!!!-

Unfortunately for Night Light, he didn’t stop to think about what might happen while his face was so close to Shining’s crotch. As soon as the cage was unlocked, the sheer force of Shining Armor’s erection was enough to shoot the metal off like a slingshot. It was beyond lucky that the hunk of metal zipped right past Night’s head, missing by mere inches and hitting the wall across the room. However, the same couldn’t be said for Shining’s cock as he sprung out like a Jack-In-A-Box, slapping his Dad’s face like some perverted comedy skit.

“OH!!!” Cadance gasped with her hooves over her mouth, but quickly bursted out in laughter. Night Light rubbed his snout with a pained look on his face, while Shining just winced and sunk into his chair in embarrassment. Cadance pointed at them with a hoof while cracking up. “Oh GODDESS!! Ha ha ha ha HAAAA!! Oh… Oh, I’m SO telling Mom about this!”

Night Light sighed and regrew a smile before looking back at her. “Hmph… Well, if you’re willing to call her ‘Mom’ directly, I’ll allow it.”

While Cadance beamed with a flustered blush, Shining tried to catch his Dad’s attention while fumbling his hooves. “Uhhh… sorry, Dad.”

When Night looked back at him, he nearly laughed when he saw how nervous Shining looked behind his erection. Despite how embarrassed he may have looked, it was quite a juxtaposition to his throbbing cock. While it may have been slightly smaller than what Night Light was packing, it still looked tremendously thick white standing atop his lap. Not to mention, as soon as it went to full-mast with his veins throbbing, Shining clenched his eyes and hissed through his teeth. “Nnnnffffff… S-Shit, SHIT!”

“Oh lemme…” Night Light was just about to reach out with a hoof to help him out, but stopped himself to turn back to Cadance. “Uhhhh… Would you rather do this, or…”

“Hmph… Well that depends…” Cadance rolled over so she was lying on her stomach, and she grinned rather eagerly at the two stallions and their current positions. “Would you prefer that I get him off? Or do you want to do it yourself?~”

His lips tightened shut, and he took a moment to breathe in through his nostrils. He looked back at his son, who was blushing just as hotly as his Dad at that moment. When he stared back at his son’s face, he could see a faint shrug of his shoulders to indicate he wouldn’t mind either outcome. And while Shining sat in silent need, Night Light slowly peered back at Cadance with his face feeling especially hot…

“Ummm… W-Well, ummm…” He took a breath with his eyes closed, and answered his Daughter-In-Law honestly. “... I… I was considering maybe… r-returning the favor?”

Cadance smiled sultrily at both stallions, and gave a strong nod without blinking an eye. “Alright then, Dad… Go right ahead~”

Night Light smiled at her lovingly, appreciating her words more than anything else. He turned his attention back to his son, who was still as hard as a diamond and leaking at the tip. Night shot his son a sultry grin, and reached down to grab hold of the base of his shaft.

“AaaaAAAHHHH!!~” Shining Armor leaned back in his seat, gripping the armrests as he throbbed hard in his Dad’s grip. “NNNNGHHHH!!!~”

“Yeah, there we go~” Night Light leaned in with his eyes closed, and gave a good lick of his tongue up the underside of his son’s shaft. The taste of his sweaty, musky flesh made him shiver a little as he moved his muzzle up his length. Right as he got up to the cockhead, Night gave a couple soft strokes and asked, “So, you want me to--”

“AHHHHHH!!!~”

Shining Armor cried out with a lumbering moan, and his cock erupted right in front of his Dad’s face. Before Night Light could finish his question, he was hit with a big cumshot that landed across his face. He was startled for a second, which left his mouth partially open when Shining spurted another rope. He groaned hard and accidentally shot right into the stallion’s mouth, which was followed by a few more throbs which littered more cum across his face. “Nnnghhhh!! NNNGHHHHH!!! OoooOOOOOoooohhhhh…”

After nearly a minute of uncontrollable ejaculation, Shining Armor slumped back in his chair with a deep and relieving moan. He closed his eyes and caught his breaths, while his cock remained stiff and coated in his baby-batter. Across from the Prince, Night Light was still kneeling across from him with a stunned look on his bukkaked face. Meanwhile, Cadance was left speechless with her mouth wide-open.

“... uhhhh…” Night Light leaned back with his eyes closed, and he tried to wipe the strings of cum off his face with the back of his hoof. He also made a brief gulp to swallow up his son’s load, much to both onus’ shock. After breathing out, he tried to lighten the mood by saying “Well, uhhhh… that worked, I guess…”

Cadance had to clutch her muzzle shut to keep from laughing out loud again. Meanwhile, her husband had his head slumped down in guilt. “... sorry, Dad…”

“Hmph~ You kidding me?” Night revealed a forgiving smirk when he looked back up at him with a perk of his brows. “If anything, that should be a compliment. I doubt many guys could make you cum that quick~”

Shining hid his face more bashfully, but his Dad could still see his flustered smile. “O-Oh, come on… I could say the same about you and Cadance.”

“Now, wait just a minute…” Cadance finally pulled herself off the bed, and she went up to the chair while Night Light was still seated on the floor. “Shining, I’m only going to say this once, and I want you to know I mean every word…”

She leaned in close to her husband’s face, and kept a sincere smirk while narrowing her eyes on him. “Night Light might have been great, but YOU are the only stallion I want to be with. And that’s a promise~”

Shining was surprised to see his wife acting so insistent about a statement so obvious. But with a shrug, he couldn’t help asking, “So, uhhh… is it gonna be weird if I… I’m not big enough?”

“PBBT! Oh, please!” Cadance scoffed particularly hard and rolled her eyes. “Shining, I’m not THAT obsessed with size! Besides, I wouldn’t want a cock as big as Night Light’s ALL the time!” After a second or two, she looked back at Night Light to add, “Uhh, no offense.”

“None taken.” Night waved his hoof without a shred of disappointment. “I can tell you were a bit tighter than expected~”

“Exactly!” She turned back to Shining and added, “It’s like… doing a workout routine. I mean, sure, I could lift two hundred pounds every day to build up my strength, but that would be WAY too exhausting! I’m not looking to push my limits, honey… What I want is somepony I love inside and out~”

That statement was more than enough to make Shining smile graciously. The two leaned in to give each other a loving kiss, while his Dad sat and watched with a touched look of his own. When their lips parted, Cadance looked Shining in the eyes to say, “I love you, Shining Armor~”

“And I love you too, Mi Amore~”

The two shared a hug after that quick exchange, but Cadance made sure not to touch him below the waist while he was coated in his own semen. However, instead of grabbing a towel with her magic or walking over to the bathroom, she caught both stallions by surprise when she sat down beside Night Light on the floor.

“Wh… What are you…” Shining Armor’s eyes widened when he realized that now two ponies were nestled between his legs. Cadance used a wing to pull her Father-In-Law close to her side, while both of them were positioned in front of that messy crotch. She leaned in to whisper into Night Light’s ear, making him go bug-eyed in silence. But soon enough, he was grinning just as wide as her when he nodded at her suggestion.

“You know…” Cadance looked back up at her husband, as was his Dad, with both of them narrowing their eyes lustfully. “... Since you and Dad assisted in cleaning me up, I don’t see any reason not to return that favor as well~”

Shining’s eyes bulged out even more, while his cock twitched especially hard between their faces. The two ponies on the floor giggled at that response, with Night being the first to ask, “So, whad’ya say? You alright with me finishing this job?” He perked his brows with a lick of his lips, which was enough to make Shining groan and readjust himself in the chair.

“Nnnnfffff… I-I uhhhh…” Shining bit his lip to better conceal his smile, but it was clear that he was wanting to grin excitedly. He may have already shot his load, but he was more than willing to keep going as he nodded his head. “Well, ummm… Sure thin--”

-BAM!!!-

Without any warning, the bedroom door bursted wide-open. All three ponies yelped out in shock, just in time to see an older mare rush into the room excitedly.

“Night Light, Night Light, NIGHT LIGHT!!!” Twilight Velvet, Matriarch of the Sparkle family, rushed into the room with her horn glowing. The off-white mare was fortunately alone, and made sure to close the doors behind her. In her aura, a piece of white plastic could be seen hovering beside her. “Night Light, LOOK! I’m pregnant! We’re going to have a foal after all! Hehehehehehe~”

The mare was hopping around all happily, while the three ponies were all frozen in stunned silence. It took a moment for Velvet to look back at them, her smile dissipating upon noticing their positions. With Shining still in the chair with his lap covered in cum, and both his Dad and wife perched in front of his twitching cock, the sight would’ve been absolutely mortifying for most Mothers to witness first-hoof. However, aside from a few seconds of uncomfortable silence between them all, Twilight Velvet blushed heavily with eyes unblinking.

“... Oh, ummm…” She took a moment to assess the situation, and reluctantly stepped backwards towards the door. “... I’ll, uhhh… I’ll wait downstairs…”

With that, the older mare quickly exited the room, clearly not wanting to get involved in whatever they were about to do. But since there were no expletives or divorce papers flying around, they could only assume that her exit was solely temporary. After the door shut behind her, the three were left back by themselves. Several seconds passed before anypony could speak, with Night Light being the one to clear his throat.

“... uhhhh, heh heh… Well… This is awkward, huh?”

The End
