When Shining and Cadance learned that their parents wanted another foal, they were absolutely thrilled! Unfortunately, since Velvet is too old to have another child herself, they had an unorthodox solution: Cadance being the surrogate for her In-Laws

Shining Armor and his wife Cadance were presented with wonderful news earlier that year: After some discussion, it seems that Night Light and Twilight Velvet want to try and have another foal! The younger couple were absolutely elated, and didn't hesitate promising to help however they could. However, neither of them expected for their parents to ask an unorthodox request from the two.

Since Velvet is too old to get pregnant again, and neither her or Night wanted to try artificial insemination, that meant they had to find a mare to be their surrogate the Natural way...

And since Cadance is literally the Princess of Love, she wasn't against volunteering with her husband to help~

Note: This story was written for the Father's Day '24 Contest happening in the Incest is Wincest group. That should give you a good idea of what to expect, including Incest (Duh~), M/M and M/F action, cuckolding, chastity, throat-play, and other lewd happenings between a married couple and their In-Law~

Chapter One - Starting the Weekend

Night One

“Hooooo boy… Okay, settle down, settle down…”

Shining Armor had his eyes closed as he took a couple preparatory breaths, needing a moment after taking a glance out the window. He had tried his best to occupy his time and remain busy for most of the day, but the Prince still found himself waiting like an antsy child. He had no idea how badly his heart was racing until he caught a glimpse of the stallion from his high vantage point. Shining nearly stumbled down the stairs while struggling to maintain a casual pace, not wanting to appear too hasty to any of his Guards or staff.

“Whooooo…” He let out a long, calming exhale while trotting down the lengthy stairs, which was thankfully unseen by any of the Crystal Ponies. There may have been a slight blush on Shining Armor’s cheeks, but that wasn’t too suspicious considering the expected guest. Even though it was fairly late in the day, almost close to evening, a couple of Shining’s personal Guards have just returned from the train station with his esteemed guest by their side. And just as he reached the bottom steps, Shining was smiling wide when he saw the main doors opening before him. “A-Alright then…”

Both Crystal Guards kept stern looks on their faces, but greeted their Prince with respectful bows when they entered the castle. Between them was an older unicorn stallion, whose blue coat and darker blue mane definitely shared similar hues to the pony before him. Shining smiled and rushed in, not giving the stallion a moment to speak before pulling him in for a tight hug. Neither of the Guards interfered, and just smiled happily when the older pony hugged Shining back.

“Ahhh, there’s my Highness! Heh heh~” Night Light, otherwise known as one of the “Royal Grandparents” to Princess Flurry Heart and the Patriarch of the Twilight family, was more than happy to give his Royal son a loving hug. Shining squeezed his Dad tight, ignoring his thoughts well enough to appreciate this moment as a genuine familial bond. After the two pulled back, Night smirked at his son and asked, “So, is Cadance doing well? I was kinda hoping to be greeted by her too~”

Shining sighed and rolled his eyes, still keeping a chipper smile when he replied, “Well, that was supposed to be the plan, but Flurry Heart kinda needed an ‘emergency cleanup,’ if you catch my drift.”

“Aaaaahhhh, gotcha.” Night Light gave a sympathetic shrug of his own. “Yeah, that sounds about right. I’ve lost count of how many times you or Twilight had to make us improvise or change our schedules a bit…” As he reminisced, the stallion chuckled and shook his head with a smile. “Aaahhhh… Hard to believe how much Velvet and I would end up missing those things.”

“Well, that’s why we’re here, right?” After giving his Dad a loving nudge, he motioned back to his Guards so they could be dismissed. The Crystal Ponies bowed politely and made their leave, allowing the Prince to have some proper time with his Father. Shining led his Dad back towards the stairs, and they trotted up side-by-side without any interruption.

“So, I take it that Mom didn’t want to make the train ride?”

Night Light scoffed a little before shooting his son a look. “What, were you wanting her to come up for this?”

He caught the cheeky tone in his Dad’s voice, indicating what he should’ve already known before asking. That caused Shining to quickly wince and avert his eyes. “Uhhh… No, not really…”

“Hmph~ Honestly, I’m glad you said that.” Night Light gave another chuckle to himself when he caught his son’s embarrassed blush. “I mean, given what we have planned, it’d be really awkward if you did--”

“Yeah, I get that, Dad! Ugh…” Shining cringed a little and tried not to bite his lip. After a brief exhale through his nostrils, he looked back at him to clarify, “So, like… is she still cool about all of this?”

“Pbbt!” Night Light raised a brow. “You think I’d be here if she didn’t? This was all her idea, after all.”

“Yeah, but that was two weeks ago…” As they reached the top of the stairs, Shining looked around to make sure nopony was eavesdropping. Despite how isolated the two appeared in such a spacious ballroom, Shining made sure to lean in and speak in a more hushed tone. “And uhhh… I just wanted to make sure before enacting any spells first, y’know?”

“Oh, you haven’t done that yet?” Night Light seemed much less nervous than his son, and just smirked while keeping a casual tone of voice. “Well, hopefully they don’t need much of a waiting time before they’re confirmed effective. We only have this weekend, remember?”

“Oh, d-don’t worry! She already talked with Twily to make sure they worked properly…” As soon as he mentioned his sister’s name, Shining shuddered a little with a more uncomfortable look. “Ugh, that was an awkward talk when she visited…”

“Oh, don’t tell me you bought up the plans with her.” Night Light paused at the top of the steps to stare at his son. “How much did you actually say?”

“Don’t worry, Cadance was careful not to say too much. Although uhhh…” Shining’s face cringed a bit when he paused briefly. “... I’ll admit Twilight looked very happy when they finished talking, so I can only assume she knows Cadance’s part in all this.”

“Well, technically speaking, everypony will know that part soon enough…” Night Light followed his son as they walked towards a large, metallic elevator at the end of the hall. Two Guards were posted at the entrance, since it was meant for Royals and esteemed guests only (as well as any differently-abled individuals). Of course, the two just nodded when Night Light entered the elevator with Shining, not saying a word. The stallions remained silent until the doors were closed, and the elevator began to make its ascent to the higher floors. With the motors whirring above them, Night Light was able to lean in with a smirk and whisper into Shining’s ear, “What’s really important is that they don’t connect her with me~”

Shining Armor closed his eyes with a long, knowing sigh that came out as more of a whinny. Night Light chuckled when he pulled his head back, able to see how deeply his son’s blush became with that remark. After a couple seconds, Shining merely rolled his eyes and nodded begrudgingly. “Yeah… Yeah, I understand that point very well, Dad…”

Night Light took that moment to lean in and give Shining a supportive nuzzle from the side. That was enough to get Shining to smile a little, but it was clear that he was trying not to feel too flustered. When the elevator finally stopped, there were no Guards to greet the two on the private floor. All that was in front of them was the short, but lavish hallway which led straight to Shining and Cadance's private quarters.

Shining exited the elevator first, with Night Light following and looking around. “So, didn’t this used to be Sombra’s bedroom?”

“Ehh, more of a harem than anything else. It took us months to get the smell out during renovations.” Shining looked back at his Dad with a smirk and added, “Don’t worry though. The bed itself is not Sombra’s. The one that was here kinda… broke when we first moved in~”

“Oh, it broke?” Night Light tilted his head with a smirk of his own. “Heh~ Should I ask how it broke?”

“Well that depends: Do you want to hear about your son’s exploits?~” Shining was standing at the doorway by that point, and paused to give his Father a coy grin and a perk of his brows. It was obvious that Shining wanted to try and fluster him a little, but Night didn’t appear too perturbed. In fact, all that the older stallion did was huff and shrug his head playfully.

“Well, considering what we have planned for this weekend…” Before Shining Armor could turn the doorknob, a yellow aura of magic wrapped around it to keep the door shut. Shining glanced back at his Dad, who walked up closer behind his son with a more determined grin. He narrowed his eyes on Shining, and leaned in close to catch him off-guard. “Yes, Shining Armor. I do want to know~”

Shining reeled his head back a little, and grew wide-eyed in response to his Dad’s direct stare. The younger stallion couldn’t help gulping nervously, while his eyes darted back and forth a couple times. “Uhhh… heh heh heh… G-Good one, Dad…”

Night Light leaned back on his hind-legs, which allowed him to stand bipedally and tower over his son. He reached out with a foreleg to brace himself against the wall, and kept a devious smirk while looking down at Shining. The Prince blushed even more profusely, not expecting his Father to get in this close. The scent of his sweat was lingering faintly through his fur, which made Shining purse his lips and nearly tremble. “Mmmm… Uuhhhh…W-What are you--”

The doorknob clicked audibly, interrupting the two when they turned their heads. It seemed that the bedroom was already occupied, and was just unlocked by whomever was inside. Shining and Night looked back at each other for a moment, with the latter sighing and stepping back on all fours. Shining needed a second to breathe out, but he was still blushing hard by the time he turned around. “W-Well, uhhh… Seems like she’s already here! Heh heh…”

Shining opened the door, and smiled when he saw a familiar face waiting by the bed. Princess Cadance was lying on her side at the edge of the mattress, and made sure to remain in that position when the two stallions entered. Her smile widened upon seeing the two, and she lit up her horn so the door could be shut behind them. “Hello there, Shining Armor… Night Light~”

With the way she was staring at both stallions with such a sultry look, Night Light ended up blushing just as deeply as his son. The two dorkily averted their eyes and chuckled meekly, which was enough to make Cadance giggle with a hoof over her mouth. “Ohmigosh, you two look SO alike! It’s adorable~”

“C-Cadance, come on…” Shining tried to wave his hoof in dismissal, but he appeared much too sheepish to keep his wife from giggling. Night Light looked equally as flustered, but he was able to shrug his shoulders before speaking up.

“Well, hopefully that won’t make things too weird for either of you…” He looked back at Cadance with a more subdued smile, and lowered his head while blushing. “And ummm… Velvet and I are really, really thankful for you agreeing to this.”

“Well, of course I would be!” Cadance pulled herself out of bed, and walked right up to Night Light to give him a friendly hug. “And please don’t act all worried or embarrassed for my sake, alright? Shining and I already talked it all out, and we have no issues with doing this for you two.”

Night Light hugged her back, and was smiling graciously when they pulled apart. Cadance took that moment to lean back in and kiss Night Light on the cheek, which made him blush even deeper. Shining was blushing a bit too, and he had to look away while readjusting his hooves. Of course, his head perked up when he heard Cadance ask, “Isn’t that right, honey?”

“Oh! Uhhh… Y-Yeah, totally…” Despite his chipper response, Shining still looked nervous when he looked back at his Father and wife. Seeing the two side-by-side, the realization was enough to make Shining’s muzzle skew worriedly. Nevertheless, he quickly breathed out and tried to smile more naturally. “Heh~ Sorry, uhhh… this is still a lot to process.”

“Hey, how do you think I feel?” Night Light tried not to scoff while looking between the two ponies. “I mean, this is technically my first time too. At least, with somepony other than Velvet…”

Shining couldn’t exactly refute that point, and merely nodded with his muzzle shut. Despite how weird this was for everypony involved, he knew that Night Light was likely more hesitant than either of them. Shining thought it over for a bit, and decided to ask, “So, did you or Mom talk about rules or anything? Like, I don’t want to break any boundaries or anything.”

“Hmph~ I think we’re already doing that, hon…” Cadance said that with a rather sly smirk, as well as a perk of her brows. Shining sighed and scratched the back of his mane, while Night Light looked away from her with a bashful smile of his own. The Princess made sure to add, “However, Shining does make a good point. Did Velvet mention anything that could be a ‘Hard-No’ for this weekend?”

“Actually, no.” He looked back at her with a surprised smile and shook his head. “In fact, she straight-up told me to do whatever it takes to make it happen. So, uhhhh… yeah~”

He smiled rather nervously, and tried not to look back at his son to see his reaction. The Prince winced a little from that revelation, but he could only shrug his head in silence. Meanwhile, Cadance responded with a chuckle of her own. “Well, I suppose that makes sense. If she’s not able to have foals anymore, I can’t blame her for wanting the best chances~”

“Well, I’m really grateful to hear that. Ummm…” Night Light paused and looked at both ponies with slight apprehension. After taking a deep breath, he decided to ask, “So, uhhh… How about you two? Do either of you have any… ‘Hard-Nos’ to bring up?”

Cadance and Shining glanced at one another, but didn’t say anything. Instead, the two gave each other a knowing look, with the Princess giving a nonchalant shrug of her shoulders. While she smirked faintly, her husband blushed a little and eventually breathed out. “Uhhh… I-I don’t think we do,” he couldn’t look back at his Dad while giving that answer, but he made sure Cadance could see the affirmative shake of his head. “Did… you have any, honey?”

“Nope!” Cadance was beaming proudly, and made sure to look back at Night Light to add, “As a Mother myself, I completely understand the importance of you and Velvet wanting another foal. And since you two made it very clear that artificial insemination is out of the question…”

She glanced back at Shining for a second, and saw him give a small nod in approval. She grinned much more confidently, and turned back to Night to add, “As your Daughter-In-law, I’m willing to do whatever it takes to be a surrogate for you and Velvet~”

To prove her point, the Princess of Love leaned in without warning and grabbed hold of the stallion’s head. Shining went wide-eyed in an instant, and could only watch as his wife planted her lips on Night Light’s. Cadance pulled her Father-In-Law in close, and held in place as they shared a deep kiss. Night was more wide-eyed than Shining for a couple seconds, but his nervous jitters went away when he closed his eyes to reciprocate the gesture. “Mmmmmmm…”

Night Light was trembling a little as he tried to stand upright, but that was easier said than done when he knew his own son was watching him. Regardless of the Prince’s unblinking stare on them, Night tried to appreciate the soft, supple lips of Cadance’s connected to his own. He tried not to open his muzzle too wide, but he still felt the smallest grace of Cadance’s tongue against his lips. When the two finally pulled their muzzles back, the stallion shuddered with his eyes clenched shut. “Nnnnghhh! H-Holy…”

He had to step back from the Princess briefly, and took a couple breaths to settle his nerves. Cadance took that moment to look back at Shining, who looked rather frazzled from seeing that adulterous moment. But much like his Dad, Shining’s face was beet-red while averting his eyes from her. “Heh… W-Wow, uhhhh… That was unexpected~”

“Well, you agreed to it…” Cadance smirked much more confidently than either of the stallions before her. She knew that this arrangement would probably be more awkward for the father and son, but she’d be lying if she said she wasn’t curious to continue. She waited a moment before asking her In-Law, “Are you okay, Night Light? I hope that wasn’t too much.”

“N-No, no… I’m good…” Night Light took another breath to get fully settled, and he huffed while smiling back at her. “Well! Ummm… I guess that’s one way to break the tension~”

“Well, at least now we can move forward and make this work…” Cadance turned back towards her husband. “Honey? You have those spells practiced?”

“Y… Y-Yeah, I do…” Shining sighed with a shake of his head, and then stepped forward to continue with this arrangement. Before he could light up his horn, he muttered to himself, “That was a very awkward conversation with Twilight…”

He first went up to Cadance, and gave her one final kiss on the lips before illuminating his horn. Night Light stepped back a few steps, and watched as his son closed his eyes and lowered his head. Cadance took a step back as well, and held her breath as she stood with her eyes closed in preparation. Shining’s magenta-hued magic circled around his wife like a sphere, completely encasing her within the bubble for a second or two. However, that magic then quickly pulled inward on all sides, encasing around the Princess and disappearing through her fur. The last of the glowing magic could be seen just beneath her tail, before a sudden zap hit her nethers and made her gasp in shock.

“OOHHH!!~” She collapsed onto her knees, and still had her eyes shut while quivering on the floor. Both stallions rushed in and helped her up, but Cadance’s knees were buckling hard as she struggled to stand upright. When she finally got back on all-fours, her hind-legs were spread apart with a wider gait with her thighs twitching in tension. Shining reeled back in surprise when he noticed a couple of fresh droplets trickling down the back of her legs, almost like she wet herself. Meanwhile, the Princess had to bite her lip while groaning under her breath. “NnnnNNNnnnfffffff~”

“Well, uhhhh…” He wasn’t sure how to feel about that spell working so quickly, but he was grateful he waited until after his Dad arrived to try it out. Cadance had to lean against the wall while fanning her face with a hoof. With a flustered huff, Shining tried to smirk playfully and say, “I think that ovulation spell worked~”

“Yeah, I can tell…” Night Light was struggling not to snicker while standing to the side. “I can smell her from here~”

“Aaaahhhh!!~” Cadance pushed back harder against the wall, even going as far as to turn around so her back could brace up against it. She stood on her hind-legs, which were still outstretched and quivering, while her wings sprung out with several antsy twitches. She used one of her forelegs to bite down on her hoof, not expecting the heat to hit her so brutally in an instant. With her other foreleg, Cadance reached down so she could cover her leaking marehood from view in such an exposing position.

“Wow…” Night Light huffed with a blushed smile, and watched his Daughter-In-Law becoming increasingly horny by the second. He had to keep himself from feeling too guilty, since he knew this was one of the only times he could get away with leering at his son’s wife. It helped when he glanced back at Shining for a second, only to see him give a light smile and a shrug of his head.

“Heh… Not bad, huh?~” Shining tried not to feel too weird about speaking about Cadance like that to somepony else, especially his own Dad. Meanwhile, the Princess herself was too lost in her own building heat to register the two stallions in that moment. She leaned her head back with her teeth gritted, and groaned while rubbing her hoof tighter between her legs. Night Light was too busy staring at the mare, and ended up blurting a response after shaking his head clear.

“O-Oh! Y-Yeah… You… Y-You’re a lucky stallion~” Night Light looked back at him for a moment, before rolling his eyes and jokingly adding, “Well, maybe not as lucky as me this weekend. Heh heh…”

That point was enough to make Shining sigh with a more uneasy look, which made Night quickly backtrack. “Oh, sorry! I wasn’t trying to make it weird, I jus--”

“No, it’s okay. I’m fine…” Shining needed a second to breathe out, but he kept a genuine smile for his Dad to see. “We already talked this all out, and… I-If you’re still wanting to continue, then… so do I~”

Night Light looked back at Cadance, who was panting through her nostrils and rubbing her marehood more vigorously. The smell of her arousal was lingering stronger in the air, causing both stallions to grunt at the same time. Shining quickly walked away from both of them, and went towards the nightstand by the bed to retrieve something. “Also, ummm… Cadance felt like this might make things less awkward if I…”

Shining had his muzzle skewed nervously when he turned around, and held a small metallic device in his hoof. Night Light’s brows raised the instant he recognized the petite, phallic-shaped item made of polished metal bars. “Oh!” He blushed even harder in realization, and stared back at his son more baffled. “Wait, is… is that for you?”

“Well, ummm… k-kinda yeah…” Shining felt uncomfortable helding the chastity cage in front of his Dad, but he motioned back towards Cadance to clarify, “She, uhhh… she was worried it might be uncomfortable for you to, ummm… like… seeing me hard.”

Night Light scoffed with an amused smirk, and his eyes veered downward for a second. Shining tried to push his hind-legs closer together, but his semi-flaccid member could be seen clear as day regardless. While it may have been a bizarre addition for this weekend, Night Light couldn’t exactly dismiss Cadance’s reason for it. He lit up his horn, and picked up the cage with his magic so he could inspect the device himself. “Hmmmm… Have you ever used a product like this before?”

“Ummmm…” Shining lowered his head in embarrassment, but didn’t try to conceal the weak nod he gave. “... a few times this week… Mostly for practice.”

“Hmph, practice?~” With a more cocky smirk, Night tossed the chastity cage back to him. Shining caught it in his hoof before hearing his Dad say, “Well, what would be really uncomfortable is putting that on you myself, so…”

Night Light gave him a sly, expectant stare that made Shining shiver and bite his lip. Without saying much, Shining just nodded begrudgingly and trotted back to the bed. Cadance’s hungry moans were becoming harder to ignore, which helped Shining to get his chastity cage on at a faster pace. Even though he was fairly hard already, his nimble hooves (as well as a convenient cooling spell for his junk) were able to slip the device over his penis without much issue. He still grunted a little when he used the tiny key to click the lock shut. “Nnnnghhhh…”

When Shining Armor sat back upright, Night Light could see how much his son’s cock was bulging within the thin bars of the cage. Since the device was curved downward, there was no way for Shining to get fully erect without massive discomfort. And in a matter of seconds, Shining was already gritting his teeth as he clenched his eyes and grunted from the building pressure. “Mmmfff…”

“AAAAHHHH!!~” Cadance had managed to reopen her eyes just enough to witness Shining slipping the cage on, which just made her even more riled-up and eager for action. Her stifled groans were enough to catch both stallions’ attention, and they looked back at her while she was mercilessly rubbing her clit. Even though she was panting heavily, she managed to speak up in heated gasps. “Mmmmffff… Shi… Shining, give… Give him the key, nnnnfffffff!!~”

Night Light glanced back at his son all wide-eyed, while the Prince just hung his head for a second. “Ughhhh…” Shining finally hopped off the bed, taking a second to adjust to his new “equipment,” before waddling back towards his Dad. He sighed reluctantly before reaching out with the key in his hoof. “She, ummm… she also wanted this to happen…”

Night Light blinked in surprise, but didn’t object when he took the key from Shining’s hoof. With Cadance still groaning and rubbing herself, the older stallion only needed a second before nodding with a smirk. “Ahhh, I see… Well, if that’s what she wants, I expect that lock to stay in place until she gets a Positive pregnancy result~”

Shining bit his lip, his expression almost looking like a remorseful cringe of sorts. But before Night Light could think to give another apology, he noticed how badly his son’s hind-legs tensed up from his statement. It was obvious that Shining needed the cage, since he would’ve gotten rock-hard in front of his own Father without it. In addition, Shining breathed out shakily before looking up at him and giving a meager nod. “Ummm… I-I… I understand…”

“Wonderful~” Night Light got confident enough to pull Shining in with a hoof, and planted a kiss on his forehead. Shining reeled back a little with a blush, but he kept a flustered smile that his Dad could see. Now with his member tightly packed in his cage, all he could do was try to place his utmost focus on the stallion in front of him. Because of that, Shining Armor took a breath before stepping back and lighting up his horn.

“A-Alright, ummm… Just stay still for a second…” Shining lowered his head so his horn was pointed at Night Light, and he shot out another surge of his magenta magic. Much like the enchantment he provided for Cadance, Shining’s aura wrapped around the entirety of Night’s body like a glowing translucent bubble. And in a matter of seconds, the magic was absorbed into the stallion’s body, dissipating entirely when it settled right between his hind-legs. Shining kept his eyes closed, but he winced when he overheard his Dad’s brief groan upon completing the spell. “Ahhhh… T-There you go…”

“NnnnNNNnnfffff…” Night Light stumbled back a couple steps, but was soon blushing as profusely as Cadance was. The Princess was still struggling to remain upright, but her hooves were starting to skid beneath her weight as she kept leaning back with a hoof against her pussy. Night Light’s face appeared strained for a moment, but he let out a sharp exhale before shuddering and biting his lip. “Ooooohhhhhh… Herrrreeeee we go…”

Beneath the older stallion’s barrel, his thick cockhead was already slipping out from his sheath. The plump, meaty stallionhood quickly sprung out from between Night Light’s legs, growing erect in a matter of seconds. Shining couldn’t help looking right at the girthy beast, which made him go wide-eyed in an instant. The younger stallion went slack-jawed when he witnessed Night’s cock springing out in full mast, growing to a length notably larger than expected. More specifically, Shining wouldn’t have guessed that his Dad had a few extra inches compared to his own…

“Aaaaahhhhhh~” Night Light sighed with a wider, more relieved smile as he settled with the new enchantment. He looked down to sneak a peek between his legs, and grinned at the sight of his stallionhood throbbing at its full length. All thirteen inches of Night’s magnificent girth were glistening after being unsheathed, with the thick veins protruding from the shaft and pulsating with every throb. It was enough to not only leave his own son slack-jawed in envy, but to also make Princess Cadance stop moaning for a moment.

“Ooohhh…” Cadance reopened her eyes long enough to see what Night Light was packing, and she gasped to herself silently. She was frozen against the wall with her wings still twitching, while her hoof continued to squeeze against her nethers so her arousal was trickling down her legs. She bit her lip with an antsy groan, and narrowed her eyes on him with a hungry stare. “Oh, w-wow… Mister Light, where has that been?~”

“Hmph…” Night Light shivered when he glanced back at her. His grin widened quite a bit, but his limbs were trembling as he felt those surges of heat coursing through him like waves. Shining Armor’s eyes darted back and forth as he looked between them, catching how intensely the two were staring at one another. It was like being caught in an open field right before being struck by lightning, with the electricity lingering in the air and leaving everything in tight, silent tension…

And whether he liked it or not, Shining Armor felt a distinct tension inside of his chastity cage too.

“Nnnnfffff!~” Night Light turned around to face Cadance, but looked down at his erection with an impressed whistle. “Whoo! Shining, you certainly got me feeling more energized~ Nnnffff…”

“Y-Yeah, uhhhh… the spell should make you more, uhhh… f-fertile and stuff…” Shining felt embarrassed specifying that detail for his Dad, and he had to avert his eyes from both ponies leering at one another so blatantly. “I-It uhhhh… The s-spell should last for as long as you stay erect, so… You might need to try and stay hard if you can between ummm… a-attempts…”

While the Prince cringed from the plural wording, which wasn’t helped when he overheard both ponies snickering. Night Light was growing more confident with himself, and even reached down with a hoof to test his new virility.

“Oooohhhhh…” He groaned as he gave his throbbing cock a couple testing strokes; he tried to slide his hoof gently, but the sensitivity from Shining’s spell caused his knees to quake. A couple thick droplets of precum smeared across his hoof before he pulled his foreleg back, leaving the fetlocks matted in a clear sheen. Meanwhile, his thick cock was twitching especially hard beneath him, and smacked the underside of his barrel with a couple meaty slaps. “J-Jeeze… S-So I… I need to stay erect the whole weekend?

“Mnnghhh, you better~”

Cadance’s voice caught both of the stallions’ attention, as she quickly pushed herself off the wall by her wings. She landed back on her hooves with a forceful lunge, landing in place like she had just soared down from the skies above. With her legs spread apart, and her marehood winking readily beneath her raised tail, her intense stare on Night Light was enough to make Shining gulp. But for the stallion across from her, that stance just made his cock throb in need. She walked up to the stallion, and wrapped a hoof around the back of his head. “And if you need any help maintaining such a thing, I’m sure that our Prince can abide as much as he can~”

Both Night Light and Shining Armor got all wide-eyed, and looked back at each other with matching blushes. Meanwhile, Cadance just smirked back at her husband and clarified, “And just for the record, you already tended to his arousal just now, so there should be no issue with you continuing as such for the weekend… Right?~”

Shining opened his mouth slightly, but nothing could come out as he blinked in silence. When he looked back at his Dad, the only response Night Light gave was a contemplative roll of his eyes. His muzzle was slightly skewed, but it seemed that his newfound horniness was forcing him to consider such a taboo option in that moment. Shining looked back at his wife in shock, but she was grinning back at him with obvious intent.

“You know…” She leaned in close to Shining, and whispered into his ear, “If you agree to do it, I’ll do whatever you want when you get out of that cage~”

He was practically bug-eyed when he stared back at the grinning Princess. He tried to look back at his father, but Night Light was too busy glancing back at Cadance’s ass with a lick of his lips. Shining’s blush deepened when he turned back to her and asked, “S-So, like… you really want me to--”

“Yes~” Cadance placed her hoof over his mouth, keeping him from saying anything more. “I really want you to do that. With him~”

Shining Armor turned his head away for a second, only to accidentally point his muzzle straight at his Dad’s twitching cock. A shuddering whinny came out as he shivered in place, while his chastity cage tensed up more notably. “Nnnnghhhh… F… F-Fuck, okay… okayI’lldoit…”

“Yay!~” She planted a deep kiss on Shining's lips, and then pulled back with a wet pop that left Shining gasping for air. Before leaving him to tend to his Dad, she made sure to whisper sultrily into his ear, “In that case, you better listen to what I tell him next…”

Princess Cadance made sure that Night Light was still gawking at her backside, and she walked over towards the bed with her tail still raised. She laid the front half of her body across the plush bedding, while her hind-legs remained on the floor with her ass fully presented. She turned her head to look back at both stallions, who were awestruck by the Alicorn’s pristine pussy on full display. After reaching back with both of her hooves, she gripped both of her cheeks tightly as she spoke in a lustful purr:

“Mmmmmm… Come on, Night Light… Shining won’t be touching any of this until you knock me up~”

Night Light exhaled through his nostrils in an antsy whinny, and he couldn’t help pushing his son aside. Shining nearly stumbled to the floor as his Dad barrelled past him, making a beeline straight towards the Princess and her waiting snatch. Before Shining could think to say anything, he caught sight of his wife’s enamored stare pointed right at him.

“And if you need any help between our sessions…” Cadance glanced right back at her Father-In-Law, and shuddered when she added, “Nnnffffff… T-Then Shining will gladly help you out like a good col--AAAHHHH!!!~”

Night Light didn’t wait for Cadance to finish her giddy remark, which almost made Shining Armor sigh in relief. Unfortunately, the Prince was still frozen with a stunned look when he saw how quickly his Dad mounted her. Due to how pent-up both ponies were, neither of them wanted to bother with foreplay or setting the mood. Instead, the stallion’s thick cockhead pressed right up against that leaking marehood, prompting Cadance to tense up and shiver through her uncontrollable moan. “OoooOOOOOHHHHH!!! Nnnnnghhhhhh…”

Shining Armor had to take a moment to look around the bedroom, just to make sure he was truly the only one present for this level of debauchery; he may have double-checked that he locked the doors and windows, but there was always a chance Discord could be watching from somewhere with a video camera and a bowl of popcorn. Luckily, the Prince was still the sole audience member present when Night Light and Cadance began their little show. As soon as Shining turned back around, he was greeted with the sound of his wife’s boisterous moan.

“AAAHHHHH!!!~” Her head reeled back, and her wings sprung out with feathers flying when she felt that first push from Night Light’s hips. The stallion clenched his eyes shut and gritted his teeth, groaning hard as he felt that supple warmth against his cockhead. His lengthy shaft could be seen clear as day from Shining Armor’s point of view, and the Prince’s muzzle went agape when he saw it visibly throbbing against his wife. With how tightly Night was pressing up against her entrance, as well as his magically enhanced arousal, Shining could only imagine that his Dad was pumping fresh strands of precum inside of her already. The Princess’ hind-legs were tensing up hard, as was her husband’s stallionhood inside that cage as he watched in blushed silence.

“... h-holy…” Shining had to fan his face with a hoof, but he still felt uncomfortably hot as he watched what his Dad was doing. Night Light continued to push with all his might, fueled by Cadance’s deep moans that were intensifying by the second. Cadance’s voice hiccuped into a high-pitched squeal the moment his flaring head worked its way past her folds. More of her syrupy juices were trickling down his length, and the scent of her arousal was strong enough to make Shining’s nostrils flare out. A weak grunt escaped his muzzle, but it was barely heard over his Dad’s shuddering groan as he kept pushing.

“NNNNGHHHH!!” Night Light kept his eyes shut, and he tried his best to keep himself from unloading into her too soon. Even though the goal was to impregnate the surrogate, he wanted to make sure he guaranteed her a proper load straight into her womb. Inch by inch, his shaft began to disappear between her quivering lips. Cadance gripped the bedsheets with both hooves, and wailed out in primal bliss as she opened up more around his girth.

“MMPHHHH!! Aaaaahhhhh~” Cadance pushed back against Night Light’s cock, which helped her to swallow up a couple more inches. As for her husband, who was still standing beside the bed with his blush ridiculously deep, he didn’t seem to realize he was looming in closer to the two ponies. Even though he was staring right at his Dad’s cock, he looked rather mesmerized by the sheer size of that veiny beast filling her up. And as he got in closer, even placing his front hooves on the mattress to lean in, the additional musk of his Dad’s sweaty cock just made him flare out his nostrils even more.

“Nnnnnffffff…” Shining bit his lip, and he tried to stay silent when he looked up at the two. Night Light continued to slip deeper inside of the mare, and kept his eyes shut so he wouldn’t accidentally see his own child beneath him. Fortunately, even with hearing Cadance’s distinct voice bellowing out in rapture, Night Light remained as hard as a rock while pumping more precum straight into her marehood.

“Aaahhhhh!!~” Cadance gave another enthusiastic push against the older stallion, and managed to get his plump medial ridge inside. Her pussy was gripping him as tightly as a vice, almost like she was trying to milk him for his load already. Shining shivered to himself as he witnessed the penetration up close, feeling surreal about the fact that it wasn’t him delivering that kind of pleasure for her. In addition, his eyes couldn’t stop veering back to stare at the remainder of that throbbing cock mere inches from his snout. Shining didn’t realize his muzzle was still partially open until he was jolted by his wife’s voice. “NnnNNNFFFF!! Oh, fuck!! Nnnnghhhh… G-G-Give it to me, Mister Sparkle!~”

“GnnaaaAAAHHHH!!~” Night Light seemed to take that response quite positively. His hips pounded in with full force, causing Shining to yank his head back before the ponies’ bodies collided. Cadance went wide-eyed with another heavy gasp, not realizing that the bulge of his cockhead was now protruding from the bottom of her stomach. Cadance lurched her head down as she clenched hard around his shaft, squeezing him well enough to make him spasm against her. “Nnnfffff, j-j-jeeze… A-Aren’t you eager~”

“Eager for you, big guy…” Cadance moaned out after taking a deep breath, and she savored every throb of that massive cock stretching her out. She lost count of how many warm, gushing throbs she felt between her legs, undoubtedly already sloshing with Night Lights fresh seed inside. Even though she was able to see her husband from the corner of her eye, she was much more enamored with Night Light while her heat was stirring her nerves. “Aaaahhhh!! Mmmmmm…”

With one final push of his hips, Night Light shuddered with a relieved moan of his own when his hips collided with her backside. Now that he was officially balls-deep, the stallion took a moment to savor the tight, comforting caress of Cadance’s folds hugging every inch. More precum was being pumped out to flood her fertile marehood, with his plump balls visibly pulsating with every throb. While the two held each other tightly in that moment, fully interlocked and shivering in shared embrace, neither of them seemed to notice when Shining moved towards Night Light’s backside…

“Whoa…” Shining Armor didn’t realize he muttered that out loud, but it didn’t stir either of them in the slightest. The Prince was staring right at that plump, muscular ass right in front of him, and trying not to look at the Cutie Marks on both sides. Instead, his eyes narrowed on the hefty pair of dark-blue balls dangling between his legs. The aroma of his musk was particularly ripe, and strong enough to make Shining quiver all over. Even his member tensed up while cramped in his chastity cage, with a pathetic little trickle of precum hanging off the tip.

“NNNGHH!” Shining quickly yanked his head back when Night Light caught him by surprise, pulling his ass back and nearly hitting his son’s snout. Cadance gripped her bedsheets even tighter, and savored the titillating sensation of that flaring head grinding against her walls. Night Light only pulled back enough for his medial ridge to tug against the inside of her opening, while several inches of his thick and veiny shaft could be seen glistening in her arousal. He could hear the Princess take a deep breath, while also feeling his son’s breath particularly close to his backside.

“Oh, Goddess…” As he remained perched behind both the ponies, seeing every curve of that muscular ass pinned between his own wife’s legs, he didn’t try to stop either of them by any means. Night Light was already getting into a rhythm, and he began to thrust into the moaning mare as naturally as he would’ve done for his own spouse. His hips pistoned back and forth, and he got himself into a vigorous pace atop of her. Meanwhile, Cadance’s hooves could be seen curling in tightly, and her wings were fluttering out with strong audibly flaps. With all of that combined, Shining couldn’t help reaching out to grab hold of his Dad’s hips. “Nnnnfffff~”

“Aaahhhh!!~” Night Light perched himself closer against Cadance’s back, and wrapped his forelegs around her torso. His hips kept thrusting back and forth, repeatedly slapping the Princess’ ass while his balls dangled so enticingly. Shining was trying his best to “help” the two, which amounted to just holding his Dad’s hips and feeling how powerfully he was pounding into her. All of it was too much to resist, and the Prince finally gave in to his own impulses.

“OOOHHHHH!!!~”

Night Light couldn’t stop thrusting his hips, even when he felt a sudden enveloping warmth clasping over his balls. Right behind him, his son was gripping his backside with all his might while his eyes were clenched shut. Not only did the Prince lunge in with his muzzle wide-open, but he also managed to wrap his lips around that low-hanging ballsack. The strong, overwhelming taste of sweat and musk hit his tastebuds like a freight-train, and caused his chastity cage to nearly bend from the sheer strain of his own erection. Not even thinking about the fact that it was the same balls that created himself, Shining Armor groaned in shameful pleasure as he held on to Night and sucked on his balls. “Mmmmmphhh!~”

“Gaaahhhh, fuck!!” Night Light couldn’t stop thrusting, and he was too lost in his own arousal to even consider pausing now. Even with the additional pleasures being delivered by his son, Night was throbbing hard inside of Cadance with every thrust he delivered. Cadance couldn’t stop moaning out in pure ecstasy, gripping that shaft as best as she could and ovulating already. She could feel every hot, gushing spurt of his precum shooting inside of her, which made her moan out without a shred of shame or patience.

“AAAAHHHH!! Nnnnfffff… OH, NIGHT LIGHT!!~” She belted out the stallion’s name as passionately as she would’ve done for her own husband. Fortunately, the sound of her boisterous voice not only brought Night Light closer to completion, but also made Shining tense up and suck those balls more eagerly. He burrowed his face in harder against his Dad’s thrusting ass, feeling the slight pulsations of those balls as they churned and began to swell out. Before too long, Shining couldn’t stop drooling as the sheer size filled out both of his cheeks, and left his muzzle partially open while wrapped around the sac. All the while, his ears twitched when he heard his wife cry out, “PLEASE CUM IN ME, DADDY!!!~”

“AAAHHHH!!!~” As soon as he heard that, Night Light spasmed with his face clenched in like he was about to have a stroke. His hips pounded against hers more erratically, which caused his son’s head to be yanked back and forth in tandem with his Dad’s writhing hips. Shining struggled to stay in place, and even went wide-eyed for a moment with some flustered flailing; but with his Dad’s balls now basically trapped inside of his muzzle, the stallion was forced to remain in place until Night was done.

Fortunately for all three ponies caught in that semi-incestuous train, a bellowing cry from the stallion in the middle prompted a quick conclusion.

“GNNNNAAAAAAHHHHHHHH!!!~”

Night Light lunged down and bit down hard on the nape of Cadance’s neck, causing the Princess to shriek out and roll her eyes back. Both of them were at the pure apex of pleasure by that moment, with Shining caught behind them to feel the aftershocks between his lips. His Dad’s swelling balls throbbed particularly hard inside of his stuffed muzzle, allowing Shining to feel the exact moment Night Light shot his first proper load. The Prince’s eyes clenched shut, but his muzzle remained as wide-open as he could while spasming second-hoof to their shared orgasms.

“AAAAHHHH!!!~”
“Nnnnfffffff!!”

Night Light and Princess Cadance remained tightly pinned to one another as he gave that first cumshot, flooding her womb as he shot into her deepest depths. Cadance twitched and writhed uncontrollably under his weight, nearly forgetting about her husband entirely in that brief moment. The thick bulge of Night Light’s head was seen pushing past the Princess’ belly-button, right before her entire stomach bloated out from the sheer volume of his ejaculation. Several thick, magically-enhanced ropes of his cum filled her to the brim with his load, to the point where her belly looked a little pregnant already.

“NNNNNngghhhh… Mmmmphhh~” Night Light’s entire body twitched for a moment while buried so deep inside of his Daughter-In-Law. His voice remained muffled for nearly a minute before finally letting go of her neck, leaving a very visible bite-mark along the side. But for the Princess herself, all she did was continue to moan out weakly between her panted breaths. The two stayed connected for quite a while, savoring that intimate moment of conception with nothing to interrupt the tranquil mood…

-POP!-
“HUUUHHHHH!!!”

… That was, until Shining Armor reminded both ponies of his presence when he yanked his head back, and pried himself off his Dad’s balls with a wet pop.

“GAH!” Night Light winced painfully from that sudden jerk, which actually hurt his balls a little. Luckily, his still-erect cock remained buried inside of Cadance when he turned his head. “Nnnghh, b-be careful back there!”

“Sorry! Ughhh…” Shining had fallen off the bed with that forceful yank, and was now sitting on the floor and rubbing his jaw. “Yeesh…”

“You’re really going to react like that?” Night Light scoffed while keeping a slightly amused smirk. “You know, neither of us told you to do that~”

“I know, I just… nnffff…” Shining sighed and lowered his head guiltily, which in turn made him look down at his still-straining cage. Night Light may have had that spell to keep him erect, but his son had no external excuse; regardless of what happened, Shining was still into this as much as either of them. In fact, Cadance giggled a little when she turned her head and saw where he was.

“Hehehehe~ You alright there, hun?”

“Yeah, he’ll live,” stated Night with a cockier tone. He looked back at her to add, “I think Shining just got a little overzealous back there~”

Shining groaned a little and tried to mutter, “D-Dad, come on…”

“What do you mean? I already did~”

“Daaaad!”

Cadance giggled with a hoof over her mouth. “Hmph~ Well, technically your Dad came in. Not on~”

“That’s right~” Night Light bent down and planted a more gentle kiss on the back of her head. “And that won’t be the last time either~”

Cadance beamed back at him with a blushing smile, and sighed with pure contentment. “Mmmm… I really hope you mean that…”

She paused just long enough to lean back and get closer to his muzzle. She narrowed her eyes on him, and she grew a more lustful smirk before adding slyly, “... Daddy~”

Shining heard the antsy inflection in Cadance’s voice, and saw the hungry grin his Dad made in response. After letting out a pent-up groan, Night lunged in and gave her a much deeper kiss on the lips, right in front of his blushing son.

“Whoa…” Shining was still sitting on the floor, and just fanned his face with a flustered huff. He knew that he shouldn’t have found this so hot, but his twitching chastity cage proved that he undoubtedly was. And by the time the two finally pulled their muzzles back, still smiling at each other with such intimate passion, Shining Armor grew a faint smile of his own.

Chapter Two - Father-Son Bonding

Day Two

“Haaaahhhhhhh… Oh man…”

It was early in the morning, with the sunlight beaming brightly through the bathroom window. The shower was running with lots of steam, but only one pony was inside to appreciate the cascading water. Shining Armor had his eyes closed, and was trying not to get lost in his thoughts while scrubbing down his fur. However, that was easier said than done when his mouth was still plastered with the taste of his Dad’s junk.

When he woke up earlier, Shining was surprised to see how contentful Night Light and Cadance looked while nestled up together in bed. He was fortunate that the bed itself was so large, even though he was sleeping at the foot of it like their personal pet. Of course, considering how long he spent “assisting” them as they shared several more romps throughout the evening, it almost felt fitting in some humbling sort of way. By the time both of them finally passed out from sheer exhaustion, Shining barely managed to get the plug inside of her before falling asleep himself.

“Whoo~” By the time he finished his lengthy shower, Shining was able to smile with a more relaxed breath. He lit up his horn to pick up the towel with his magic, and he floated it into the shower after turning off the faucet. As he dried himself off, he grunted a little when the towel graced across his chastity cage. His Dad may have been able to cum multiple times last night, but Shining still hasn’t. “Mmphhh…”

“Uhhh, Shining? SHINING?!”

The sound of his Dad’s frantic-sounding voice made him stop his drying and bolt out of the shower in an instant. He almost slipped on the bathroom floor, but managed to keep his hooves steady when he reached the door. When he opened it up, Cadance was no longer in the bedroom. Night Light was sitting by himself in the middle of the messy bed, with his eyes wide-open and his semi-flaccid cock in his hooves.

“GAH!” Shining instinctually reeled away when he caught sight of that, but he quickly sighed and held up his hoof apologetically. “Uhh, sorry… force of habit.”

“Shining, I think the spell is wearing off!”

“OH!” The Prince rushed over to the bed, where he could get a closer look at his Dad’s ailment. Night Light was trying his best to keep himself hard, but his frantic strokes were only leaving his thick cock ‘al dente’ at best. Shining looked around in a panic and asked, “Wait, where did Cadance go?!”

“She was called by a message from Celestia and had to leave for something. Her horn kinda… w-went off while we were asleep?” Night Light kept trying to rub himself, even needing to close his eyes so he could focus better. “Nnnnffffff… I-I think she left a note…”

Shining noticed the folded paper on Cadance’s nightstand. He used his magic to float the note over, while his muzzle skewed from the sound of his Dad’s strained groaning. When he opened the note, he found his wife’s hoofwriting in beautifully pink ink:

‘Shining,

Celestia informed me that a Diplomat from Mount Aris has arrived at the Crystal Empire today. I promised them that I would show them around the Crystal Empire personally, and I didn’t want to break that on such short notice. I’m really sorry! I PROMISE I’ll be back as soon as possible!

-Love, Cadance’

Shining sighed with his eyes closed, remembering that deal himself; the offer was made months ago when he and Cadance visited the Hippogriffs for trade deals, and he almost completely forgot about it. When he reopened his eyes, he noticed an additional note written by her at the bottom:

‘P.S. Don’t worry, I still have the plug in! (I have a camouflage enchantment to make it invisible in public) Just focus on Daddy while I’m gone~’

Despite the sharp exhale from his nostrils, Shining couldn’t help blushing a little when he glanced back at his Dad. By that point, Night Light was showing a lot of struggle while lying on his back. He was gritting his teeth and trying to rub himself, but his cock was only slightly harder than it was before. Shining almost got lost in thought while staring at that meaty stallionhood, watching as the hoof glided up and down the muscular shaft like silk. His blush deepened in realization when he looked back at the note, and then at his Dad again.

“Mmmphhh… I-I need some help, please!”

“R-R-Right! Right…” Shining put the note down, and climbed onto the mattress to crawl up towards him. He lit up his horn, relieving Night Light’s forelegs as he magically grasped his stallionhood. While it may have not been as tantalizing as actual physical contact, the unique tingling and warmth around his cock was enough to help significantly. Night Light hissed through his teeth and tensed up on the bed, leaning his hips upward while his cock stiffened in Shining’s aura. “Uhhhh… I-Is it working, Dad?”

“Nnnnfffff… Y-Yeah, a little…” Night Light reopened his eyes to a slight squint, and bit his lip when he stared up at his son. Shining couldn’t look away from his Dad’s cock while using his magic, so he was forced to watch it getting harder. He certainly appeared awkward in that moment, since it was just him stimulating his Dad and not Cadance. But alas, considering everything he already did the previous night, Shining wasn’t against morphing his aura around Night’s shaft for a better grip. “OOOooohhhh… Oh, f-fuck…”

Shining bit his lip, and focused on that daunting cock as his aura turned to a singular ring around the shaft. It was difficult trying it on a cock that wasn’t his own, but he got his magic to slide up and down his Dad’s length like a semi-invisible hoof. A sharper moan belted out of Night’s muzzle, causing him to grip the bedding with both hooves and take a couple breaths. “Mnnnghhhh… Yeah, there we go…”

It took a couple minutes, but Shining’s magic was enough to get his Dad’s cock rigid and standing atop his waist. His horn was glowing brightly as he maintained his aura as best as he could, although he needed to stick his tongue out in concentration. The magic kept sliding up and down his shaft, until Night’s cockhead started to flare out. A thick glob of precum could be seen bulbing right at the tip, lingering in place and causing Shining’s tongue to slide across his lips. “Mmmfff…”

“Oh, goddess that’s nice…” Night Light kept his eyes shut, and he laid back with his forelegs behind his head as he savored the sensation. He groaned and readjusted his hips, which made his cock swing back and forth a little bit. Shining grunted in frustration, since that made it a little trickier to keep a steady grip. Even though the ring of magic was still doing its job, Shining eventually huffed and turned off his magic. The sudden stop made Night Light wince a little, and he looked up at his son while rock-hard. “Mmnghh, what gives?!”

“Sorry, that contortion of my magic is tricky to do for longer than a couple minutes…” To make up for it, Shining breathed out in a flustered huff before moving in closer between Night Light’s legs. Despite a split-second of hesitancy, Shining gulped nervously before reaching out with a hoof. He grabbed hold of his Dad’s fat cock, and started to stroke his length the more “natural” way. “Nnnffff… Is… Is that better?”

He tried not to avert his eyes from his Dad, even though it was awkward to be tending to his erection by himself. Shining almost wished that Cadance was here to supervise things, even though that very thought sounded really weird in his head. But at the same time, Shining’s muzzle skewed as his blush remained visible across his cheeks. Regardless of blood relation or social taboos, the younger stallion couldn’t deny how… impressive his Dad’s cock looked up close.

“Aaahhhhhh… Oh, fuck yeah~” Night Light shivered from the tantalizing strokes given by Shining’s hoof. Even though he knew better than to look at his son’s face while being jerked, Night Light couldn’t resist smirking a little. “Heh~ I knew you said the Crystal Castle provided a ‘Hooves-On Royal Treatment,’ but I wasn’t expecting it to be so literal.”

“Ugh…” Shining rolled his eyes and shook his head. “Really, Dad?”

“Hey, I’m just trying to lighten the mood…” Night waved a hoof in dismissal of his son’s flat expression, and re-closed his eyes to better appreciate his touch. He moaned out a little when Shining jerked more vigorously, which caused more precum to spurt out in thin strings. Shining’s fetlocks were soon covered in the clear and syrupy substance, while the growing musk began to waft towards Shining’s face. The masculine scent was more than enough to make Shining groan through a clenched muzzle, shuddering a little as he tried to keep a steady pace.

“Mnnnghhh… Damn, you’re good at that…” Night Light tried controlling his breaths while laid back, not wanting to accidentally get too pent-up and cum before Cadance returned to the room. But in his clouded, lust-addled mind still afflicted by Shining’s magic, the stallion eventually reopened his eyes with a more sensual stare. He took a moment to watch Shining working his cock, with his hoof vigorously stroking and his face frozen in concentration. But at the same time, Night could see that Shining had a particularly intense look while staring at his Dad’s glistening cockhead.

“Hmmmmm…” Night Light only gave himself a moment of contemplation before shrugging his shoulders, and asking, “So, Shining… you wanna use that muzzle of yours again?~”

Shining was startled enough to yank his hoof back in shock. “W-What?!”

“What do you mean, ‘What?’ You literally sucked my balls last night, remember?”

Shining cringed with a shameful sigh, and made the very unfortunate mistake of face-hoofing himself. Night Light heard the wet ‘Splat’ of Shining’s precum-soaked hoof slapping his cheek, before the Prince groaned and reeled his head back. The moment he realized what he did, it was too late as the fur across the bridge of his snout was now visibly matted in a clear sheen.

“Hmph~ Not a bad look on you…” Night Light snickered to himself while Shining used the back of his foreleg to wipe off his face. The older stallion waited for him to put his hoof down before adding, “Besides, I’m not asking you to finish me off or anything, okay? Just think of it like… giving a little upkeep, that’s all~”

Shining sighed and stared back at his Dad with a flat look. “... You just want to get a blowjob, don’t you?”

“Well… I mean, yeah. What stallion wouldn’t?” Night Light shrugged his head with a self-serving scoff, but he made sure to continue speaking before Shining could try answering his rhetorical question. “Besides, Cadance instructed you to help me in any way you could, and… Well, I’m not gonna lie, I’m curious to see what you can do~”

Shining looked back at him with an uneasy, but still profusely blushed expression on his face. Even as he kept his muzzle shut, his eyes could be seen slowly veering back down to Night Light’s cock. More precum had collected around the top of that flat, flaring cockhead; in addition, a couple thick strands were slowly trickling down the underside of his shaft. Shining tensed up with his hooves curling in, but his Dad could hear the nervous gulp he made.

“... Is that a gulp of nervousness, or are you showing me what you wanna do?”

“Oh, c-come on! Dad, please!”

“Please, what?~”

Shining was taken aback for a split-second, while Night Light grew a more devious grin on his face. After perking his brows a couple times, he motioned down to his still-rigid member and waited for a response. Shining needed a couple seconds before tilting his head warily. “Uhhhh… w-what?”

“Come on, play along for your Daddy…” Night Light knew how wrong this all was, but he couldn’t resist continuing on while his heart was racing with excitement. He reached down and began stroking his cock himself, splaying himself out to lie in a more seductive position on the bed. As he jerked his fat cock, making a show of it while staring Shining down, he kept his smirk nice and wide before opening his muzzle. “Mmmmfffff… The next word I want to hear out of your muzzle is ‘Please’... And after that, you can finish the rest of your statement however you want~”

With the way he perked his brows once more, it was clear what Night Light was implying. Shining lurched his head down to hide his face, but his blush was radiant enough for it to show through his mane. He knew exactly what his Dad was wanting him to do, and it should’ve been enough to make him second-guess everything they’ve been doing so far. But alas, with his chastity cage still straining hard and leaking between his legs, Shining Armor closed his eyes with a defeated sigh. “Ughhhhh… f-fine.”

“That doesn’t sound like ‘Please’ to me, your Highness~”

“Nnnffff! Ugh… P… Please…” After he corrected himself, Shining looked back up to see his Dad’s grinning face. Night Light continued to stroke himself, and used his other hoof to motion for him to continue. Shining hated the idea of saying it outloud, but he felt compelled to do so anyway. Shining closed his eyes, and took a deep breath before clearing his throat, “A-Ahem! Ummm… Pl… Pleaseletmesuckyourcock…”

Shining muttered that statement so fast and weakly, that Night Light huffed with a dismissive shake of his head. “Come on, soldier boy… You can do better than that~”

He wanted to be more upset about that little jab, but Shining knew that his Dad was technically right. After another slow exhale, Shining responded by reopening his eyes, and looking at his Dad rather meekly.

“Ummm… P-Please let me… s-s-suck your cock, Daddy~”

“Therrrrrreeee we go!” Night Light let go of his erection to give a teasing clap of his hooves. “Nicely done, son! Was that so hard?~”

“Well, you’re my Dad, so… Yeah, it kinda is!”

“Okay, fair enough. Dumb question…” Night Light rolled his eyes with a shrug, and then leaned back so his waiting cock was on full display. “Aaaahhhhh… Come on then. Go right ahead~”

Shining almost hesitated as he readjusted himself, nestling in closer to his Dad’s waist. He closed his eyes before opening his muzzle wide, and he leaned downward with his tongue sticking out. The musk around Night Light’s cock was so thick and heady, that Shining was able to taste it in the air already. He shuddered with his fur sticking up, but that wasn’t enough to stop him as he moved in and felt the tip of his tongue make contact.

“Nnnnnnnnn…” His whole body trembled the instant he got a proper taste of his Dad’s shaft, as well as that sizable glob of precum that his tongue picked up. He took a long, teasingly slow drag up the length of Night Light’s cock, causing it to twitch and spasm in place. Night Light gasped and closed his eyes, using bote forelegs to hold onto the sheets tightly. As the strong, familial flavor of his Dad grew stronger in his mouth, Shining’s chastity cage began to leak as profusely as the cock pointed at his mouth. “Aaahhhh!~”

“NNNGHHH!!”

As soon as his open, drooling muzzle reached Night’s cockhead, all he heard was that sharp groan before a thick rope of pre spat right between his lips. A more high-pitched, almost slutty-sounding moan came out of Shining’s mouth, just before he pulled his tongue back in and closed his lips. He clenched his eyes shut before swallowing that small, flavorful load in his mouth with a strong shiver. The sound of his audible gulp was enough to make Night Light moan in response, with another rope shooting out and landing right across Shining’s muzzle. “Aaahhhh!!~”

Shining Armor couldn’t take it anymore. Not caring whose cock was driving him so wild, he was driven by the strain of his own erection as he sank deeper into depravity. Before his Dad could give him another premature facial, Shining leaned in and grabbed hold of the shaft with both hooves. With the cock throbbing hard in his grip, Shining’s impulsive groan was cut off when his lips wrapped around that fat cockhead. “Mmphh~”

“AaaaAAAAAHHHH!!!” Night Light let go of the sheets, instinctually grabbing hold of the back of Shining’s head. “Mnnnghhh!! F-F-FUCK!!~”

“Mmmmmmmm…” The diligent Prince kept his eyes closed, and pushed his head in so his Dad’s could slide across his drooling tongue. The sheer girth of all that cockmeat was enough to nearly gag Shining before it even reached the back of his throat; although, as soon as he pursed his lips around the top of the shaft, a couple strong pulsations could be felt as more precum shot directly down his gullet. In response, a couple small, but intense spurts shot out of Shining’s cage to litter across the sheets.

Night Light continued to moan out deeply, and he tightened his grip to push his son’s head down. Shining went wide-eyed for a second or two, but he was able to re-close them before groaning hard around that twitching girth. A thick bulge of Night’s cockhead began to appear at the top of Shining’s neckline, while the Prince struggled not to let his Dad trigger his gag-reflex. His lips began drooling more profusely, which helped to slide them further down his shaft without pause. Even when he felt his muzzle becoming completely blocked with all that enhanced cock, all he could think to do was keep sucking like a good stallion should. “Mmmmmm…”

“Nnnfffffff, yeah, take it~” Night Light eventually reopened his eyes, and grinned down at the top of Shining’s head. Seeing how much of his cock had disappeared past Shining’s lips, Night had to look away for a split-second so he wouldn’t accidentally cum from the sight. Of course, he was still twitching rather antsy as he felt Shining’s soft, pillowy lips hugging him so well. His hooves pushed down on Shining’s head a little harder, before letting go and allowing him to slide back up his shaft. “Aaaaahhhhh…”

Shining Armor nearly choked on his Dad’s cock, but he managed to keep his throat relaxed and snugly wrapped around his Father’s head. He started to bob his head back and forth, sliding his lips across Night’s length and pumping out more of that delectable pre. The bulge of that flaring head could be seen traveling up and down the son’s neckline, throbbing hard enough to pulsate through his white fur. Shining could feel each spurt of the stallion’s warm, gushing seed shooting down his gullet, causing him to tremble in place and leak more profusely. If his cock wasn’t locked up so tightly, he would’ve likely came before his Daddy did.

“Mmmmmmm…” Shining’s eyes closed more naturally as he grew more enamored with the primal urges sweeping through his body. The cockhead was swelling inside of his throat, to the point where it became difficult to even work his head up and down the shaft. His face tensed up a little, even as he continued to slather every inch of that thick cock that his lips could reach. All the while, he could hear his Dad’s voice turning more intense as he grew closer to climax.

“Aaawwwwww, fuck!~” Night Light was throbbing harder in his son’s mouth, and his lustful inhibitions began to take over. His hooves began pushing down on Shining’s head repeatedly, while the Prince slobbered all over his length. Both of them knew that they shouldn’t have gone that far already, especially when their Princess was waiting for another creampie later. But in that private moment between the stallions, all that they wanted to do was keep going in pure perverted bliss.

“Yeah, take Daddy’s cock~” Night Light grinned down at Shining and pumped his hooves stronger, causing those slutty lips to slide closer towards his base. Despite the obvious strain in his son’s expression, it didn’t seem to deter him either. In fact, Shining’s hips were starting to thrust in the air while more precum trickled out from his cage. And from the looks of it, Night’s goading words were making him go even harder in encouragement. “Mmmmffffff!! Damn that muzzle’s good…”

Shining Armor had to let go of the base with both hooves, but it could still be felt twitching strongly inside of his muzzle. His eyes reopened in a panic, and he tried to yank his head back before accidentally setting his own Father off. Unfortunately, along with the size of that cockhead becoming too large to slip out, it didn’t help that Night Light tightened his grip against his head. In fact, the older stallion moaned out more intensely before shoving his son back down a few inches.

“Aaaahhhhh!~” Night Light’s legs tensed up, his hooves curling from the sensations hitting his nerves so intensely. His mind was lost in a total fog of pleasure, leaving him unable to stop if he tried. His hips thrusted up against Shining’s face, which made his balls smack the bottom of his son’s chin. Just as he reeled his head back with his eyes clenched, Night Light pushed down as hard as he could so his medial ridge was crammed inside of that mouth as well. “Aaahhh!! AAAHHHH!! NnnnnNNNNNnnnghhhhhh…”

Shining’s eyes rolled back, just before shutting tightly when he felt that torrent of cum gushing down his throat. He tried his best to pull back, but that flaring head and his Dad’s grip ensured that he remained in place. Night Light cried out in pure ecstasy, and he writhed on the bed while unloading every drop he had. As for poor Shining, who couldn’t even breathe in that moment, his body squirmed while guzzling every drop like he was his Dad’s living condom.

“Mmmphh! MMPHHH!~” Night Light’s sudden orgasm lasted for nearly a minute straight, which felt much longer to the younger stallion choking on his cock. By the time Night Light’s throbs began to soften inside of that drooling muzzle, Shining’s eyes were rolled back in a more painful manner. Luckily, his head wasn’t convulsing just yet, and Night was able to let go of his head after a relieving sigh. With the last of his strength, the Prince yanked his head back hard enough to pry himself off that fat cock and fall to his back. “HUUUUHHHHHH!!!”

Shining Armor was left gasping for air as he writhed on the mattress. Night Light needed to take a few calming breaths, still lying on his back while his cock stood triumphantly. Every inch was now slathered in his son’s saliva, and the entire length was still twitching without being touched. After a moment of calm, Night Light looked down at his gasping son with a sympathetic wince. “Uhhhh… s-sorry about that.”

“Nnnghhhh… It… I-It’s fine…” Despite needing to cough a couple times, Shining thankfully didn’t throw up or pass out from that near-suffocation. In fact, by the time he managed to glance back at his Dad, he was able to show a faint smile behind his blush. “Heh… I uhhh… I think I should be the one apologizing…”

Night Light breathed out with one last big exhale, before reaching down with a hoof to grab hold of his shaft one more. Since he just shot his load by accident, he tried his best to keep himself hard before Cadance returned. “Mmmfffff… w-well, ummm… I think we’re both guilty of pushing our limits there…”

He closed his eyes to better concentrate, making sure to keep a tight grip on his shaft while pumping at a steady rate. All the while, Shining watched with an enamored blush while biting his lip, almost looking envious already. His legs tightened in together, but that didn’t do much to hide the antsy twitches from his cage. Shining eventually looked away from his Dad, blushing more sheepishly as he considered what to do next.

“Hmph~” Night caught a glimpse of Shining’s meager expression, which made him smirk and narrow his eyes. “What’s the matter, Shining? Missing your Daddy’s cock already?~”

“Nnffff!! D-Dad, come on!”

“You sure that’s what you wanna say?” Night Light grew a more perverse grin, and his cock remained nice and stiff in his grip. Shining clenched his muzzle as he looked back at him with a nervous blush. Night just huffed amusedly and raised a brow in his direction. “Or maybe you want the same thing your wife does…”

With the way Night was stroking his cock while speaking, Shining had to turn his head away with a brief shudder. He hated to admit it, but he was still just as turned-on as his Daddy was. He grunted a little and tried to readjust himself, but it did nothing to quell the strain inside of his cage. He breathed out faintly before looking back at him with the faintest of shrugs. “Mmmghhh… W-Well, uhhh… I mean… M-Maybe sometime we--”

-CLICK!-

The metallic sound of the door unlocking caused both stallions to turn their heads in an instant. Night Light tried to cover himself with a blanket, while Shining scooted a few feet away from him. Luckily for the two post-coital stallions, it was only Cadance who trotted into the bedroom. She sighed with a frazzled shake of her head, using her magic to slam the door behind her. “Ugh, oh my gosh… I should not have worn that stupid plug during breakfast…”

“Uhhh, h-hey, Honey…” Shining tried to give his wife a wide and innocent smile. “How… How was the meeting?”

Cadance closed her eyes and used a hoof to pinch the bridge of her snout. “Nnnnghhh… Well, let’s just say that Hippogriffs have a very keen sense of smell…”

Both stallions grew wide-eyed in horror, before Cadance raised a hoof and clarified, “Don’t worry, neither of them said anything about it. I… I may have tried to imply that Shining was too tired due to ‘work,’ and… Well, that seemed to give them a better assumption than the truth.”

“Hey, I’d believe it.” Night Light huffed with a more relieved shrug, and pulled the blanket of his lap. He went back to stroking his cock, but tried to speak casually towards his In-Law. “I mean, you are the Princess of Love. I bet half of Equestria would assume you leave my son drained on the regular~”

“Wow, seriously?” Shining gawked at the sheer audacity of his Dad’s statement. “Yeesh, you could’ve worded that with more tact.”

“Heh~ Says the stallion who just blew me.”

“Nnnghh!! D-DAD!”

“Oh, really now?~” Cadance immediately turned her attention towards her husband, taking note of his instant blush. While the Prince sat all bug-eyed with his pupils darting around, Night Light just shrugged with a smirk back at her. The Princess turned to him and asked, “So, that’s what you two have been doing while I was gone~”

“Well, I had to stay hard for the spell, and uhhhh…” Night Light bit his lip when he glanced down at his (thankfully) still erect cock. He tried not to look too guilty when he confessed, “I… I may have accidentally… y-you know…”

There was the slightest skew on her face for a second, most likely from disappointment that some of his precious seed was wasted. But at the same time, the Princess was able to roll her eyes and shrug in understanding. “Well… That’s alright, you guys. I left you two by yourselves, so I can’t blame you for needing to do a little upkeep while I tended to business…”

To prove her point, Cadance crawled onto the bed without any hesitation, and gave both stallions forgiving kisses on the cheeks. The two blushed sheepishly, with the younger needing to scratch the back of his blue mane. “Heh… W-Well, ummm… According to the spell, it might take a few more minutes before he can uhhh… Get another round…”

Shining nervously smiled back at his Father, nodding in approval for him to continue like usual. Night Light chuckled without any complaint, and went back to stroking himself to get throbbing once more. As for Cadance, she accepted that answer with a nod of her own, and turned herself around on the mattress. “Well, that’s not too bad. And if you have a couple minutes to spare…”

Princess Cadance bent herself over, stunning both stallions as she got into a ready position with her ass sticking up. Her chin and forelegs rested on the bedding, while she looked back at the two with a hungry gleam in her eyes. “Mmmmmm… Oh, Shining…”

With that sing-song tone of voice, Cadance lifted her tail to show off the thick base of her plug. A bright pink, plastic button was sticking out while her marehood was wrapped tightly around the rest of the toy. The base could be seen pushing in and out, almost as if the Princess was trying to pull it in completely. And around her puffy lips, Shining groaned through his teeth when he saw the instinct sheen of cum still slathered around her opening.

“Get in there~” She stared right at her husband, causing him to blush deeply and spurt through his cage. While frozen in place, Shining couldn’t look away from her plugged snatch when he heard her say, “Get me ready for Daddy. NOW~”

Shining shuddered with a faint breath, and obliged as he loomed in behind her. Night Light was still lying on his side, and watched with an approving grin as Shining grabbed hold of the Princess’ waist. He lit up his horn briefly, but then turned it off in preference of using his hooves instead. With a shuddering moan, Shining grabbed hold on the base of her plug and started to pull it back. “Nnnfffff…”

“Aaahhhh!!~” She tensed up with her back arched up, and her wings fluttered out from the titillating tug. “Mmmffffff!!~ Oh yeahhhhh…”

Night Light continued to watch intently, grinning as he watched his son get right behind her. Shining took a deep breath, and caused his wife to yelp out when he yanked the plug out with one good pull. Like a fancy bottle being uncorked, the sheer volume of Night Light’s cum sloshing around inside of her caused a thick spurt to come out and hit Shining right in the face. But instead of reeling back in disgust, or even groaning to himself in discomfort, all that the naughty Prince did was lunge in the moment his wife was unplugged.

And much to Night’s surprise and immense approval, Shining Armor held Cadance tightly while his muzzle was planted right up to her gushing creampie. “Mmmmmmfffffff!!~”

Shining didn’t hold back by any means. With how hard his cock had gotten inside of his cage, he worked on pure lustful inhibition while catching the ripe scent of his Dad’s cum. He rolled his eyes back while lashing his tongue, burrowing it deep inside and allowing that thick torrent of cum to gush inside of his muzzle. Without even thinking, the Prince began to clean her out with his muzzle drooling, and thick bulges of his Dad’s load moving down his neckline.

“AaaaaAAAAHHHH!! OOOHHHH!!!~” Cadance reeled in pure titillation while her husband got himself a huge slice of creampie for himself. She pushed her face against the mattress while moaning in rapture, embracing every hungry flick of the cuck’s tongue. “MMMPHHHH!! Aaaahhh, AAAHHH!! D… D-Don’t STOP!!!~”

“Glk… Glk… Glk… Glk~” Even if Cadance had told him to stop, it was doubtful Shining would’ve listened at that moment. All he could do was close his eyes tightly in shameful contentment, and take big gulps of that virile load to sate his cravings. His tongue pushed in deeper to lick at all of his wife’s folds, eager to get her ready for another filling. By the time he finally pulled his muzzle back to breathe, he gasped while his mouth was covered in his Dad’s musky sheen. “Aaaaahhhh!!~”

“H-Holy shit…” Even Night Light was stunned by his son’s actions, but he couldn’t stop jerking off to the depraved sight. He watched as his son moved back in, keeping his eyes closed while giving deep laps of his tongue around the outside of that winking marehood. More globs of cum were dribbling out of her, which he licked up while moaning between breaths. Night knew that he should’ve been disturbed by his son’s enthusiasm, but he wanted nothing more than to use his throbbing cock once more. “Nnnnfffff… S-Shining, move out of the way!”

Without warning, Night Light let go of his cock and crawled towards the two. He got right up beside his son, actually pushing him out of the way when he saw that his wife’s marehood was “cleaned” thoroughly. He couldn’t help lunging in with his tongue sticking out, and he got himself a few good laps at the Princess’ supple folds. Shining was surprised for a moment, but he quickly moved back in to try and share with his Dad. While Night Light pressed his open muzzle against her, slipping his tongue inside to keep her moaning sharply, Shining took the opportunity to wrap his lips around her petite little clit.

“AAAHHHHH!!~” Princess Cadance reeled her head back with her tongue sticking out, fully relishing the experience of two passionate stallions eating her out at the same time. Even though she still felt full to the brim with Night’s sloshing loads, she fully embraced both of their muzzles as her nerves were set ablaze. Night Light burrowed his face in even tighter, intent on devouring that supple pussy and making her squeal like a little piglet. His tongue-lashing only lasted a couple minutes, but it was enough to get his cock rock-hard while Cadance moaned heavily.

“Oooohhh!! OOOHHHH!!!~” Cadance gripped the sheets and fluttered her wings, loving every second of those two muzzles teasing her between her legs. Despite how ravenously Night Light was eating her out, his son was providing just as much pleasure while flicking his tongue against her clit. The stallions worked side-by-side, not even fazed when their tongues occasionally touched while sharing her pussy. Eventually though, the Princess’ moans were able to subside when their lashing tongues lessened in intensity…

“Aaaaahhhhh… Mmmmm… Huh?” Cadance soon heard the stallions’ voices intensifying behind her, but neither of them were tending to her anymore. She took a couple panting breaths before turning her head; she was just about to ask what was up before gasping eleatedly. “OOOHH!~”

Night Light and Shining Armor were still nestled closely together, but their muzzles were planted against one another to share a deep kiss of their own. The father and son held each other tightly, making out while their eyes were peacefully closed shut. Cadance didn’t say anything for a moment, and just watched with a smile as the two kissed with lots of tongue. Both of their muzzles were coated in the sheen of Cadance's nectar, with the syrupy sweetness driving them wild in incestuous pleasure.

“Mmmmmphhhhh…” Cadance’s wings stiffened greatly, while her marehood convulsed in front of the two stallions. It wasn’t until she cleared her throat that the two pulled away, their faces wide-eyed in sudden realization. It was obvious that neither of them planned to do such a thing with the other, and it left them rightfully stunned silent. Fortunately, a light giggle from Cadance helped ease the tension before she said, “You know… If the two of you wanted to keep doing that, I wouldn’t complain at all~”

Shining’s face practically exploded with a heavy blush, while Night Light just clenched his muzzle with an uncomfortable wince. But when the two glanced back at each other, neither of them said anything for a second or two. However, Night Light was the first to give a brief shrug and speak. “Ummm… Listen, uhhh… Let me talk with your Mother first, okay?”

That remark just made Shining cringe really badly. “Ughhhhh… seriously?”

“Hey, I don’t like the idea of having that conversation either!” In fact, Night Light shuddered a little as soon as he said that. “Yeesh… Still, uhhhh… She IS my wife, and she deserves to know before either of us… you know…”

Shining blinked a couple times, and stared back at his Dad in surprise. “Wait, you… Do you want to keep… ummm… d-doing that?”

Despite how bizarre both of them felt about the topic at hoof, Night Light gave another shrug and admitted, “I… I mean… L-Let’s just focus on this for now, alight?”

“Y-Yeah! Yeah, I totally agree…” Shining closed his eyes to let out a flustered huff, and nodded hard enough to help shake his head clear. “Uhhh… should we uhhh… keep going then?”

He motioned back towards his wife, who was still presented right in front of their faces. Luckily, she was still rearing to go with her pussy winking. Seeing how open the two stallions were to keeping things so close, Cadance had to bite her lip with an antsy groan. “Nnnnnffff… Guys, you have n-n-noooooo idea how hot you’re making me~”

Night Light was the first to look back at her with a lustful smirk. “Heh… Well, speaking of that, I do feel like I could go for another round…”

Shining smirked just as wide, but he was looking back at Night more than his own wife. “Well then… at least let me make up for wasting your previous load…”

The Prince nestled down towards his Dad’s waist, and he closed his eyes as he gave a couple deep laps up his shaft. The older stallion moaned out with his head reeled back, while his son grabbed hold of his cock with a hoof. Shining used his other foreleg to pull Night up to his hooves, all while stroking that fat cock and licking the head. Night Light soon found himself back on his hooves, right before Shining pushed him towards his wife.

“Yeah, get in there~” Shining practically pulled his Dad onto Cadance's back, before moving down and embracing his cock more blatantly. He gave that thick stallionhood several hard strokes with his hoof, while his open muzzle moaned out with his tongue slathering all around that flaring head. He helped physically guide his Dad’s cock, prodding it right up against his wife’s waiting marehood. “Nnnnfffff… Alright, here we go~”

Night Light only needed to give one hard push of his hips, and his cockhead was swallowed up by the mare’s loosened folds. The Princess quivered in unfathomable pleasure, and squeezed hard around his throbbing girth. And even with the remainder of his shaft sticking out and twitching, Night was still moaning hard when he felt Shining’s tongue slathering across every inch.

“Mmmmphhhh…” Night Light paused only a second to look down at both of the younger ponies, smiling to himself while reeling in insurmountable pleasure. He knew that he likely had many, MANY more sessions to go before their weekend was complete. But at the same time, even without knowing for sure whether his seed took already, Night Light already felt as satisfied as a stallion could be.

“Oh yeah…” Night Light petted the back of his son’s mane, while the Prince kept tasting his cock. “Nnnffff… Yeah, I’m definitely gonna talk with Velvet later~”

Chapter Three - Confirmations

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
