Blueblood tries out some absorption magic on a few stallions.

Prince Blueblood discovers a rather peculiar spell, which has quite kinky effects when used on other stallions. Of course, he gets right to work on "testing" the spell on a few of Equestria's finer males.

Yet another fic inspired by a delicious piece of porn. This time a piece by "sb". Which...apparently is already based on a fic. So this is a fic based on a pic which is based on a fic. Inspiration-ception?

Contains: Huge cocks, cock growth, cock shrinking, light bondage, and some cum inflation.

Let us begin, then

“Hmmmmm...what a particularly fine morning.” Fancy Pants thought out loud before taking a deep breath, staring out the second-floor window of his mansion, getting quite a lovely view over Canterlot; made even lovelier by the rising sun coming up over the tops of the buildings. Still in his night robes, the stallion had just risen from bed a few minutes ago, waking up quite early to have some time to himself before his usual busy day of socializing.

Out of the corner of his eye, he spotted a bit of yellow magic aura down near the gate around his property, tilting his head down to watch it as it flew over towards the mailbox before disappearing, seemingly having gone inside the box.

“Hm? A letter this early in the morning?” he raised an eyebrow for a moment, not used to getting mail this early in the morning. “Oh well. I suppose it might be something important.” he smiled softly before turning from the window and trotting out of his room, quietly making his way through the nearly-silent mansion.

Once outside, he took another deep breath and sighed happily, before trotting down the cobblestone walkway towards the gate. “I wonder whose social gathering I’m being invited to today...heh!” he chuckled softly as his horn glowed and pushed the gate open, before he trotted over to the ivory-colored mailbox, opening it up with one hoof.

As he peered inside, he spotted a single card, and upon pulling it out with his magic, he noticed that it was being held shut with a royal Canterlot seal. “Oh, my! An invitation to the castle? I would be remiss to dismiss the missive.” he grinned eagerly and quickly tore the seal to open the card, glancing over the handwriting within.

“To Mr. Fancy Pants-

Greetings and good day, Fancy Pants. I am writing to inform you of a wonderful discovery in magic that I have made, and would like to share with you. Perhaps you could even share it with your lovely wife as well, but I digress! If you visit the castle today, I’ll be more than happy to show you this wonderful spell. Do come alone, though, as I want to keep it out of the public eye for now.

-Prince Blueblood ”

“Hm! How wonderful. An invitation from the lovely Prince of Equestria.” Fancy Pants chuckled softly as his magic folded the letter again, slipping it into the pocket of his robes. “I could certainly use a break from the usual events around here.” he grinned as he trotted back up the cobblestone path towards his mansion.

After his usual morning routines, Fancy Pants set out towards the castle in the late morning, quite eager now to learn what the prince had in store for him. "Not often I hear about the prince discovering new magic...hm. Must be something magnificent, then!" he grinned as he trotted up to the castle, being greeted by one of the guards, who then escorted the fancy stallion up to Blueblood's chambers.

The royal guard knocked softly on the door a few times before turning and leaving Fancy Pants alone outside the prince's quarters, the door creaking open with magic only moments later. There, at the other end of the room, was none other than Blueblood himself, lounging on his extravagantly large bed while grinning over towards the door.

"Ah, there you are, Fancy Pants." Blueblood sat up and brushed his hair out from in front of his right eye, watching the other unicorn enter the room. "So glad you could make it." he grinned and slowly got up from the bed, stretching his neck a bit.

"I wouldn't miss it for the world, my prince." Fancy Pants chuckled softly and smiled as he approached the lounging prince, finding it a bit strange that he was brought to Blueblood's bedroom, but remembering that he had wanted to keep whatever he had out of public knowledge. "Whatever is the occasion?"

"Like I said, Fancy Pants, a wonderful new magic I've discovered." Blueblood kept his eager grin as he walked over towards a table at the other side of the room, where various refreshments had been laid out as they usually were. "Would you care for some wine?" he asked while his horn glowed, levitating one of the wine bottles as well as two crystal glasses, filling them both with the dark red liquid. One of the glasses however, looked like it had already been filled with wine previously. “I always enjoy a nice toast with my breakfast.” he added with a playful grin.

"That would be lovely." Fancy Pants nodded and grasped one of the glasses with his own magic, bringing it closer to his snout and taking a decently-sized gulp from it, sighing happily. "So, Prince Blueblood, what is this new magic you have stumbled upon, hm?" he looked inquisitively towards the prince, raising an eyebrow. "I don't mean to speak out of turn, but you don't really seem like the type of pony that would study magic."

The prince was busy taking a hefty swig of his own drink, sighing and licking his lips before glancing back over towards Fancy Pants. "Well, I'm not. It just so happened that my dear aunt had assigned me to oversee the rearrangement of one of the older wings of the library." he explained, lightly swishing the liquid in his glass. "Out of sheer curiosity, I looked into a box of dusty old scrolls and pulled one out. It looked rather interesting, so I took it with me, though I haven't been able to actually try it out, you see." he continued, taking another gulp of his drink. "It's meant to be used on another, not on oneself."

"Hmm, I see..." Fancy Pants nodded, "Well then...I’m always up for some experimentation. Whenever you're ready, I suppose!" he grinned eagerly before taking another sip of his wine, watching Blueblood intently. "Show me this magic of yours, old chap."

"I most certainly would, but...you see, it requires a bit of...preparation, first." Blueblood's grin curled into a playful smirk as he turned to the side and put his front hooves up onto his bed, his flaccid member wobbling a bit between his legs as it slowly hardened; quite visible now to the other stallion.

Seeing this, Fancy Pants looked shocked for a moment, honestly not expecting anything of this sort, before he grinned back. "Oh, so this is what you meant when you said I could share it with my wife?" he chuckled again and finished off his glass of wine, setting it down on the table again. "I should have expected something of this nature from you, Blueblood." he added with a chuckle.

"Well, what are you waiting for? As the Prince of Canterlot, I order you to service my royal scepter." Blueblood's grin curled into a smirk as his stallionhood continued to stiffen between his legs; his head already filling with naughty thoughts of the events to come.

"But my prince, I'm married," Fancy Pants gulped softly, looking rather confused. “I thought you meant...I didn’t know you wanted to do something...well, like that, with me.”

"I bet you're just using that as an excuse," Blueblood teased, "Besides, I've read the gossip columns. We both know that Fleur has been getting some action on the side. Why should she be the only one having affairs?"

A light blush crossed Fancy Pants' cheeks as he heard this command. He hadn't engaged in this type of activity with another stallion in quite some time, leaving him somewhat out of practice; a bit of worry and doubt starting to crop up as he wasn't sure that he could adequately please the prince. "O-Of course." he nodded softly and approached the poised stallion, glancing down between his legs at the quickly-hardening shaft and the two hefty orbs that hung below it.

He then knelt down and leaned in closer to the growing erection, his blush deepening as his nostrils were filled with the powerful scent of the royal stallion's musk. He shook his head a bit as he tried to calm down, reminding himself that the prince had chosen him of all stallions to personally service his member; an honor that only the noblest of the nobles would receive. "Here goes nothing..." he then opened his mouth just enough to slide his tongue out a good distance, brushing it across the swelling flare of Blueblood's erection.

"Mmnh...that's a good stallion..." Blueblood let out a pleased sigh as he felt the slick tongue gently teasing his shaft, helping it to stiffen up faster. In the meantime, his horn glowed as he levitated over another glass of wine, slowly drinking from it as he enjoyed the light pleasure of Fancy Pants' tongue, feeling it repeatedly slurping over the tip and first few inches of that thick royal scepter.

As Fancy Pants continued to drag his tongue over the hardening length, his horn began to glow as well, using his magic to gently caress and fondle the prince's balls, getting a pleased groan from him in response. After only a few more moments of this, Blueblood's member reached its full size and hardness, throbbing lightly in time with his steady heartbeat. Even so, Fancy Pants continued to service it with his tongue, having become somewhat intoxicated by the arousing musk, as well as the pleasant salty taste of the throbbing shaft.

"Wonderful...mmm...right where I want you..." Blueblood closed his eyes and smirked again, continuing to groan softly from the pleasurable slurps, while his horn began to glow once more, beginning to cast the new spell he had learned. The glow of his magic aura could then be seen between Fancy Pants' legs, engulfing the noble stallion's own erection, roughly halfway erect and still hardening.

Fancy Pants didn't notice it at first, though as he kept licking at the big flare of Blueblood's member, he felt a faint magic tingling coming from his own pride, though he ignored it for now, not wanting to cease his oral work unless the prince ordered him to. After a few more licks, he opened his mouth wider and pressed his lips against the flare, slowly engulfing it and gently pursing his lips around it, beginning to suckle on the tip of Blueblood's shaft. With his lips around it, he got a slightly stronger taste, and could also more clearly feel its steady throbs, which helped to arouse him further.

"Ahh...such a wonderful mouth you have, Fancy Pants." Blueblood sighed happily as he enjoyed the pleasure, already starting to reward Fancy Pants with a few sizable drops of precum, which were quickly slurped up by the fancy unicorn's tongue. It was then that Blueblood finally began to work the spell that he had learned; his horn glowing and surrounding Fancy Pants' twitching erection with that same glowing magic aura.

As the magic took effect, Fancy Pants didn't particularly notice much, only feeling a tingly pleasure around his shaft, and assuming that the prince was rewarding him for his oral service, when in reality, something much different was happening. Each passing moment, Fancy Pants' erection seemed to shrink at a steady rate, losing inch after inch of length and girth as the magic took its course, while at the same time, Blueblood grunted in pleasure, feeling a much more potent tingling in his own shaft.

While Fancy Pants' erection shrunk, Blueblood's gained size, almost as if the prince was siphoning the other unicorn's endowment and using it to swell his own. "Mmmnh...!" he closed his eyes and moaned as he felt his erection throb with power, rapidly gaining size and pushing further into Fancy Pants' mouth; that big flared tip flaring out even larger as it swelled from the magic. "Oohh...keep going, Fancy Pants...your prince is very pleased!"

"Mmph?!" Fancy Pants groaned confusedly as he felt the throbbing royal scepter suddenly swell bigger in his mouth, especially the thick flare which seemed to be growing at an alarming rate. From what he could see, Blueblood was merely increasing the size of his endowment, so he continued to suckle on it for a few more moments, but as that flare kept thickening and flaring out more, he began to panic.

He pulled his head back from the swelling cock, the fat flare pulling past his lips with an audible "POP" before he panted softly, looking up towards Blueblood. "Mmnh...my apologies, Prince Blueblood...but you really should tell me beforehand if you're going to increase your size in the middle of fellatio!"

Blueblood chuckled softly and smirked as he glanced down at Fancy Pants, his member still swelling larger and thicker with the siphoning magic, having gained at least three extra inches so far. "Mm, my apologies, Fancy Pants...I had just gotten so carried away with your lovely service...oooh...as well as working the magnificent spell...which appears to have worked wonderfully!"

"Hm?" Fancy Pants tilted his head to the side a bit, raising an eyebrow. "You used the spell already? I didn't particularly notice anything...what did it do?"

"See for yourself." Blueblood then used his front hooves to push Fancy Pants onto his back, standing over him with that same smirk from before still on his face.

Fancy Pants grunted softly from the impact, though as he lifted his head to look down between Blueblood's legs, he gasped quite loudly from the horrifying sight. "Wh-what magic is this?!" he stammered, blinking a couple times in disbelief, seeing his own stallionhood at roughly 25% of its original size, while Blueblood's was still gaining inch after inch of length and girth, growing well beyond its normal size. As Fancy Pants' erection shrunk, Blueblood's throbbed larger, releasing a couple gushes of precum every other throb.

“Nnggh...magnificent...is it not?” Blueblood grunted and shifted his hips downward, lightly grinding his swelling shaft against Fancy Pants’ deflating dick; the magic ceasing when the other unicorn’s member was only a couple inches long, while Blueblood’s had gained at least four or five inches, as well as a good deal of size to his flare. All of the concentrated magic on his shaft had brought his orgasm very close, now on the brink of climax.

“I’m...my endowment...has shrunken?” Fancy Pants gulped, his pupils shrinking to pinpoints at the horrific sight before his eyes; his mind spiraling into disbelief. “What have you done?”

“I’ve simply...mmnh...borrowed some of your length, Fancy Pants!” Blueblood spoke between soft panting and lustful groans, trying his best to hold back his impending orgasm just a bit longer. “And it appears...that it has worked quite wonderfully- nngh!” he grunted and closed his eyes again as the spell finished with a jolt of pleasure, easily sending the prince over the edge.

Before Fancy Pants could respond, that swollen royal scepter began to gush, shooting off thick volleys of steamy seed all over his body, splattering his upper body and face with streaks of the hot cream. Blueblood meanwhile groaned out loudly, his hips instinctively bucking a little as his engorged endowment unloaded more and more of his royal seed all over the other unicorn; his balls seemingly plumped up a bit larger as well from the schlong-siphoning spell.

The prince managed to leave Fancy Pants’ chest and face completely coated in colt-cream before his orgasm subsided; his haughty smirk returning as he looked down at the mess he had made all over Fancy Pants. “Or rather...mm, borrowed most of your length, I should say.”

The fancy stallion below coughed and shook his head a bit, rubbing his hooves over his eyes to wipe away some of the prince’s seed before looking up again, a somewhat deep blush crossing his cheeks now. “Well then...it...it IS temporary, right?” he bit his lip gently as he looked down at his tiny stallionhood again, feeling quite intimidated now by the prince’s improved size.

“Oh, of course, Fancy Pants. I wouldn’t dream of emasculating a stallion in that way...well, permanently, that is.” Blueblood chuckled again, stepping up from atop Fancy Pants’ body, glancing down between his own legs to gaze upon his grown erection, licking his lips gently at the pleasing sight. “As much as you surely want your endowment to return, I’m afraid it will have to wait. I’ve got more guests to see that will be arriving any minute now.”

"Hm...? What do you mean?" Fancy Pants raised an eyebrow as he looked over at the prince, though just as he saw that big white horn glowing with magic, he shuddered, feeling a sudden fatigue coursing through his body. "Mmnh...P-Prince Blueblood...!" he softly groaned before he collapsed, losing consciousness before the prince's magic forced him into a deep sleep.

"Sleep tight, Fancy Pants my dear." Blueblood smirked a bit and levitated the stallion's body, laying him across the couch at the other side of the room. "Now to wait for my guests to arrive...hm..." he glanced over towards the wine bottle again, briefly considering taking another drink, though he didn't want to intoxicate himself to the point of forgetting this lovely experience.

Climbing back up onto his bed once more, he laid back against the pillow and gazed down at his engorged erection, lightly stroking a hoof along its new and improved length. "Mmm...and this was just a single stallion..." he thought out loud with an eager grin, feeling his shaft twitching in arousal against his hoof as naughty thoughts entered his head; imagining just how big his royal scepter would grow after siphoning size from his next guests.

Sliding his hoof down further, he felt his bloated orbs, noticing that they were a little bigger than before, and a good bit heavier too. "Hmm, so...it not only absorbs length and girth, but capacity as well." the prince sighed contently, before his ears perked up, hearing the sound of hoofsteps coming down the hallway outside his room. "Wonderful, my guests have arrived!"

While said guests were arriving, it was the hoofsteps of four guards approaching his room, carrying the guests via magic. Blueblood's magic opened the door for them, revealing the group of guards levitating two stallions with their magic, as well as a very large minotaur. The stallions both seemed unconscious, but the minotaur was very much conscious, still struggling against the magic binds that held him.

"We have brought the subjects you requested, Prince Blueblood." the guard in front spoke, before all three guests were levitated forward and set down on Blueblood's bed. The guards all bowed simultaneously before backing out of the room and closing their door behind them, leaving the prince to his privacy once more.

"Mmm...wonderful." Blueblood smirked as he looked over the three subjects; a large red Earth stallion, a jet-black pegasus, and the hugely-muscled minotaur who continued to struggle in vain; his wrists held together behind his back, while his ankles and knees were tied securely together as well. "Hm, someone is certainly anxious." he teased while his magic slowly removed the ballgag that was preventing the minotaur from speaking.

"IRON WILL DEMANDS TO KNOW WHAT'S GOING ON!" the minotaur roared just milliseconds after the gag left his lips, glaring angrily up at the prince in front of him, ignoring the stallion's huge erection for the moment. "This doesn't look like a seminar-improvement seminar, and your letter did not say anything about kinky bondage!"

The prince still smirked, chuckling softly to the minotaur's apparent anger. "My apologies, Mr. Iron Will. I must have gotten the letters mixed up. However...if you're willing to stick around, perhaps this could persuade you to stay?" his magic then levitated a large, bulging cloth sack over to the bed, placing it down in front of Iron Will and pulling it open in the process.

As the minotaur gazed inside, his angry glare immediately changed into a wide grin, while his eyes temporarily turned into golden coins. "Iron Will gladly accepts your persuasion!" he eagerly replied, gazing at what must have been over a hundred small golden coins inside the bag.

"Mm, wonderful." Blueblood chuckled at the display of greed, before turning his head towards the other stallions, both of them starting to awake. "You stay put now, Mr. Iron Will...I've got other guests to attend to." he said, though the minotaur wasn't paying attention at all, still fixated on the bag of wealth before him.

As Blueblood stood up on the bed, the jet black pegasus groaned softly, blinking his eyes open, still a bit dazed from the sedative magic that had affected him. "Mmngh...where...what happened?" he went to move his hooves, but found that they were bound together with magic. "What the? Huh?" his panic was delayed as he leaned his head back onto the bed and saw Blueblood approaching, though from this angle and position, the prince's massive royal scepter was the first thing to catch his eye.

"Thunderlane, is it?" Blueblood spoke with a soft smirk, sauntering up beside the pegasus; the twitching shaft between his legs less than a foot away from other stallion's snout. "So sorry for bringing you in on such short notice, but I was...passionately curious, one could say."

"Wh-what the fuck..." Thunderlane gulped as that thick stallionhood came so close to his face; his cheeks blushing deeply from the conflicting thoughts this situation was bringing. Here he was bound on top of a bed next to...royalty, of whom seemed to be quite aroused. "What do you want, man?"

"That's 'Prince Blueblood' to you, peasant." Blueblood scowled a bit, raising a foreleg and pressing his hoof down against Thunderlane's sheath, grinding against it somewhat firmly. "You'd best watch how you speak to me, Thunderlane. While my intentions are not villainous, they very easily could be."

Thunderlane groaned softly, squirming underneath the prince's hoof, though his sheath reacted rather quickly to being rubbed, swelling a bit as his shaft began to push forth from it. "Nngh...y-yes...Prince Blueblood." he grunted, feeling his cheeks blush now as the prince continued to tease his sheath, inevitably causing his stallionhood to harden.

"Wonderful. Now, let us begin, shall we?" Blueblood smirked once more, turning his gaze to the pegasus' crotch as his hoof continued to stroke and grind along that hardening shaft; his own endowment still throbbing eagerly despite blowing a load just minutes ago. "That's it, Thunderlane...harden up for your prince."

"Nngh...wh-why are you doing this...Prince Blueblood?" Thunderlane sighed softly, gradually starting to enjoy the pleasure from the smooth hoof rubbing his shaft, though he couldn't shake the nagging fears in the back of his mind, still completely confused as to why he was here.

"Well, as I said...I was rather curious about a certain magic I had discovered." Blueblood grinned toward the pegasus' face again, pressing his hoof down a little more firmly against his hardening shaft. "So far, it seems to be working, but I want to try it a few more times, just to be sure. I thought you would make a perfect test subject."

Hearing the words "test subject", Thunderlane began to panic a bit, though the firm press to his member only made him groan and squirm again, sending a jolt of pleasure through his body. In roughly a minute, he had become fully hard from the prince's rubbing, maxing out at about fifteen inches; average size for a pegasus of his stature. "Ahh...i-if you say so..." he groaned in response, feeling somewhat scared, but also remembering that the prince said he had good intentions.

"Mm, yes...now, hold still, Thunderlane." Blueblood smirked once more as he took his hoof off the pegasus' shaft, before he stepped forward and stood over Thunderlane, glancing back to position himself just right. Moving forward ever so slightly, he positioned his body perfectly so that his pristine white orbs hung just over the pegasus' face, mere inches away from his eyes. "Perfect. Now for the test..."

With that, the prince's horn began to glow once more, using the same spell that he had used on Fancy Pants, causing Thunderlane's twitching erection to become surrounded with the magic aura. As the magic quickly took effect, Blueblood sighed happily while Thunderlane moaned softly, both of them receiving a tingly pleasure in their stallionhoods; Thunderlane's slowly shrinking while Blueblood's gained even more length and girth.

As Blueblood's balls plumped up though, they hung even lower, soon making contact with Thunderlane's face, resting atop his snout and beginning to press against his closed eyes. Just the feeling of those warm, musky orbs pressing against him made him blush even deeper; his erection twitching and throbbing harder despite its rapidly shrinking size.

Meanwhile, the larger red stallion awoke rather silently compared to Thunderlane, blinking his eyes open to see the other two stallions before him, causing his eyes to open wide in shock. He watched as the white stallion’s balls seemed to swell larger and rounder against the pegasus’ face, though from this angle, he couldn’t quite see Blueblood’s shaft extending further and gaining more girth. "What in tarnation..." he gulped softly while his normally calm mind quickly began to panic, overloaded with confusion at this odd situation he found himself in.

“Mmmnh...oh yes, that’s quite lovely…” Blueblood leaned his head back a bit and sighed contently as the magic faded, leaving Thunderlane’s erection just as small as Fancy Pants’, while his own erection had swollen noticeably thicker and had gained a few more inches, now almost touching his chest. As that monstrous cock throbbed and twitched, large globs of pre oozed from it, splashing down onto Thunderlane's crotch. "It appears my test is even more successful than I thought, Thunderlane." he teased with a smirk, looking back at the pegasus as he shifted his hips ever so slightly, rubbing his huge orbs back and forth along Thunderlane's face; each orb roughly the size of a softball and quite heavy with the loads of royal seed within.

Thunderlane only groaned softly in reply, being much too aroused to even think about what the prince said. He normally wasn't very attracted to stallions, but the dominance this prince was showing just seemed to turn him on beyond belief. With his vision impaired by the massive balls against his face, he hadn't noticed his own stallionhood shrinking; only the tingly magical pleasure that coursed through it during the process, leaving him even more aroused and eager for more pleasure. Without even thinking about it, he began to nuzzle at the two plump orbs resting on his face, taking a deep breath of the thick, musky scent that surrounded them, before sighing blissfully.

"Well, Thunderlane? What do you think?" the prince smirked and finally lifted those two huge family jewels from Thunderlane's face, giving him a clear view of the matching royal scepter just above. "I think it worked quite well...mm...as for you however..." he chuckled and lifted a hoof, stroking it along Thunderlane's shrunken shaft, eliciting soft moans from the pegasus.

"It's...big..." was all Thunderlane could say before he felt the prince's smooth hoof on his shaft; seemingly a lot more sensitive than usual. Glancing down further though, he gasped as he saw how small his penis had shrunken, his eyes widening from the sudden shock. "Wh-what?! What did you do to me?" he gasped, squirming against his binds again while Blueblood smirked.

"Do not fear, Thunderlane...I've simply borrowed your length for the time being. It looks good on me, does it not?" Blueblood chuckled and lifted his hoof again, before he shifted his hips back and teabagged the pegasus once more with his oversized orbs. As he did this though, he noticed the other stallion out of the corner of his eye; more specifically, he noticed said stallion’s fully-hard erection sticking straight up from between his legs, lightly throbbing in time with his heartbeat.

“Hm, what is this?” he turned his head towards the Earth stallion, who looked rather embarrassed; anxiously squirming against the binds that held his hooves to his chest. “Enjoying the show are you, Big Macintosh?” Blueblood smirked playfully and stepped off of Thunderlane, turning towards Big Macintosh now and gazing down at the sizable shaft between his legs. “My...you’re quite large, too, it seems.” he licked his lips gently as he positioned himself over the red stallion, pressing both of their erections together. While Big Macintosh’s was quite large, it was still at least five or six inches shorter than Blueblood’s, but with comparable girth.

“E-Eeyup…” Big Macintosh gulped softly, stifling a groan as he felt his stiff length being rubbed, twitching softly against Blueblood’s engorged meat. Compared to Thunderlane, he had a bit more experience dealing with other stallions in this way, leaving him not as nervous, but he had never engaged in any colt-cuddling of this sort. Turning his gaze towards his crotch, he watched as Blueblood shifted his hips back and forth, grinding the two rock-hard stallionhoods together and smearing a good deal of precum between them.

“So glad to, mmnh, hear it.” Blueblood sighed contently from the light pleasure, soon lifting one of his front hooves and bringing it down between his legs, pressing it against Big Macintosh’s shaft, which only caused the two erections to rub together even more firmly. “I’m certainly enjoying this...ungh...new size...as well.” he closed his eyes and grunted softly as he worked his magic, trying not to become overwhelmed by his own lust; all of the swelling down there causing him to feel quite pent up and eager for release.

Just as with the other two stallions, Blueblood’s magic aura quickly engulfed both of the throbbing lengths, before shrinking one and swelling the other, adding even more size for Blueblood while reducing Big Macintosh’s. “Mmmnghh...oh yes…!” Blueblood groaned out rather lustfully as the magical pleasure was even greater than before, mostly due to the fact that he was siphoning size from a much larger stallionhood. As his erection swelled with extra inches, his balls plumped up even further, becoming so pent up and full that each throb of his royal scepter released a drop of pre, oozing down all twenty-eight inches of its length and flowing onto the plump, heavy orbs below.

“Ohhh, how wonderful this is…” Blueblood sighed once more as the magic faded, once again leaving his ‘victim’ with a very shrunken endowment, only a couple inches in length, though with three stallions’ sizes absorbed now, Blueblood had to be one of, if not the biggest stallion in Equestria. The massive flared tip was just underneath his chest, still oozing drop after drop of precum from his overfilled balls. “Such a magnificent size! Your prince is quite pleased.”

Seeing his new size, Big Macintosh's pupils shrunk rapidly while his jaw dropped a bit, quite shocked at what the prince’s magic had done to him. Blueblood however smirked once more, bringing his hoof down to the Earth stallion’s jaw and pushing it up, closing his mouth again. “Mm, careful now, Big Macintosh...if you leave your mouth open too long, I might just stuff it full of royal meat.” he teased, licking his lips softly as the other stallion stared back up at him. “Do not fret though, Little Macintosh will be just fine.”

With all three stallions drained of their endowments, Blueblood turned his attention towards the large minotaur at the other side of the bed, who was still fixated on the large bag of coins in front of him; seemingly having been like that this whole time. "Hmm...if I remember that mythology textbook correctly, Minotaurs are much more endowed than ponies." Blueblood glanced inquisitively at Iron Will as he stepped away from Big Macintosh, approaching the minotaur now and peering between his legs.

He certainly did see two sizable orbs dangling between Iron Will's legs, though his sheath appeared to be somewhat small, at least, compared to his own. "Hm. Interesting. Oh well...your turn, Iron Will." he grinned once more, placing a hoof on the minotaur's rump and giving it a playful smack.

"Huh? What?" Iron Will snapped out of his trance-like state, blinking a couple times as he looked back over his shoulder at Blueblood. "Can't you see Iron Will is busy ogling his money right now?"

"Hah! Quite the greedy one, I see." Blueblood laughed as he slid his hoof down a bit to the minotaur's waist and pushed him over onto his side, and then onto his back with another gentle push. "You can ogle your money all you want afterward, as for right now, your prince wants to play." his grin curled into a smirk as his hoof stroked over Iron Will's sheath, while his horn glowed and teased the two blue-furred orbs below with tingly magic.

"Iron Will is no pillow-biter!" Iron Will growled, vainly trying to move his arms behind his back, though his cheeks blushed a bit from the unicorn's stroking and fondling of his sheath, which slowly brought out his member.

Blueblood continued to stroke his hoof over the minotaur's sheath though, soon moving onto that growing shaft as it pushed forth, seeming to be quite small at first. "Hmm...what was that? You want me to have some fun with you?" he smirked up at Iron Will as his magic levitated over another sack of gold coins, placing it on the minotaur's beefy pecs.

"Uh...o-oh, yes! Yes, Iron Will doesn't object to that at all!" Iron Will grinned wide as he saw the second bulging bag of coins plop down on his chest. "For the right price, Iron Will will do whatever you say, pony!"

"Hmm, wonderful. Although..." Blueblood raised an eyebrow as he gazed back down at the minotaur's endowment, still quite flaccid, but it only seemed to be a good five or six inches in length. "Are you sure you're a minotaur? You're awfully...small, for someone your size."

"Huh? Oh, uh, that..." Iron Will chuckled and blushed a bit, grinning down at the stallion. "Iron Will knows, it's really tiny now, but...Iron will is a grower!" he smirked a bit more confidently, "At least, that's what Fluttershy told me!"

"Interesting." Blueblood glanced back down at the minotaur's small shaft, this time focusing his magic on it and stroking the length up and down. "If you insist...I was just under the impression that minotaurs were quite large in endowment."

"Nngh, we are! Just you wait and, ah, see!" Iron Will groaned from the magical teases, leaning his head back onto the bed as he tried to relax into the tingly pleasure, thinking of whatever naughty things he could to try and make his endowment erect faster. Slowly but surely, his member grew hard, and as it did, it quickly gained length and girth, growing at an even faster rate than Blueblood's did previously.

The prince blinked and widened his eyes to this sight, staring in disbelief as the minotaur's shaft grew and grew before his eyes, as if some kind of magic was causing it to grow. Just to make sure, he stopped his own magic and pressed his hoof against the length, beginning to stroke it up and down as it stiffened and grew rapidly, and even without his magic stroking it, it continued to swell. "Astounding...! Where is all of this coming from?" his white-furred cheeks tinted lightly red from the arousing sight; his own huge shaft throbbing and twitching even more between his legs, oozing large drops of pre onto the comforter.

"Aah...as Iron Will said...Iron Will is a grower!" came the minotaur's response; smirking much more confidently now as he felt himself growing harder and harder every second, his once six-inch meat now well past sixteen inches and still expanding as loads of blood rushed to it. The prince could only watch in awe as it continued to grow, seemingly without end; his hoof idly stroking up and down its massive length.

"Simply magnificent..." Blueblood bit his lip gently once the minotaur's shaft hardened up to its full size, just about the same size as the prince's, give or take an inch. The feeling of that monstrous minotaur member throbbing against his hoof only turned him on even more; his own shaft rigid as ever and twitching eagerly, oozing glob after glob of pre down its length. Of course, with his lust through the roof, Blueblood felt quite an urge to stuff his engorged meat into a tight orifice, though he was getting another idea on top of that, taking into account the success of the spell he had used.

"I suppose it's now time for your end of the deal, Mr. Iron Will." Blueblood smirked as his horn glowed once more, this time wrapping a magic aura around Iron Will's midsection, slowly turning him over onto his belly, though propping him up on his knees as well. Gazing down, the prince was greeted with a rather handsome rear, along with those massive goodies that dangled between the two muscled legs, gently licking his lips again as his shaft gave a slightly harder throb, splashing a large glob of pre onto the comforter.

"Deal?" Iron Will raised an eyebrow, looking back at Blueblood again. "Iron Will didn't agree to any kind of deal! I don't know what you're...oh." he blinked as he looked at the two large sacks of cash in front of him, blushing a bit as he remembered why the prince had given them to him. "N-Nevermind! Do as you wish with Iron Will!"

Blueblood chuckled softly as he placed his hooves on the minotaur's rump, gently patting it. "Oh, I most certainly will. Consider yourself very privileged, Iron Will. It's not often that I engage in this type of activity with non-pony races." he teased with a smirk, before pulling himself up and mounting the minotaur from behind, grunting softly as he felt the massive flared tip of his shaft bump against the tight pucker, smearing a bit of precum onto it. "And really only because I find the size of your endowment to be...quite riveting."

"Ngh...thanks...I suppose." Iron Will grunted softly from the bump to his rear, his cheeks blushing from the feeling of the warm, sticky liquid smearing across his backdoor, along with that rather huge flare pressed against him, throbbing in time with the prince's quickening heartbeat. "Just...be gentle with Iron Will...his rear is a little sensitive." he admitted with a deeper blush. He was so used to being the top that being on the bottom for once was leaving him quite nervous.

"I'm afraid that I don't do 'Gentle'." Blueblood smirked and pressed his hips forward, prodding his flared tip against the minotaur's pucker again, smearing more warm precum onto it while beginning to slowly penetrate it. "Certainly not with my endowment nearly twice its size...mmnh...I want to get as much use out of this spell as I can!" he then thrust his hips forward, roughly forcing the first five or six inches inside, grunting and closing his eyes from the tight squeeze around his swollen length.

"Agggh...!" Iron Will growled as he was suddenly penetrated, closing his eyes tightly as well, though his member gave a strong throb from the shock of pain and pleasure, slapping against his abs. Only moments later, he grunted as he felt the prince push deeper with another thrust, sliding another few inches inside his near virgin-tight rectum.

"Ohhh, my...how wonderful...aahh!" Blueblood groaned and leaned his head back a bit, his hips already starting to instinctively buck forward, all too eager to sink more of his magic-enhanced shaft inside the minotaur's clenching rear, managing to fit roughly half inside after a few more moments. "N-Not even my aunt's personal assistant is this tight!" he grunted with a bit of a smirk, holding tightly to Iron Will's waist as he leaned further forward, feeling his warm precum smearing along the tightly-squeezing insides as his shaft continued to slide in deeper and deeper.

“Of course...nngh, like I always say...if Iron Will is on his knees...his rump will give a tight squeeze!” Iron Will grunted from each push and thrust the prince gave, feeling that monstrous shaft pushing further into his snug depths; the decadent mix of pain and pleasure only amplified by the massive flare that accompanied the sizable stallionhood inside him.

In just a few more moments, Blueblood had managed to sink at least three-fourths of his length inside the snug rear, sighing and groaning contently from the sheer tightness of the minotaur’s insides, which seemed to be repeatedly clenching and squeezing around that massive royal scepter. “Mmmnh! Oh yes...your prince is going to enjoy this very much.” he groaned with a lustful smirk, sliding his hooves up near Iron Will’s shoulders as he leaned forward, preparing to give the minotaur a good bucking.

"Oogh...!" Iron Will grunted and grit his teeth lightly from such a deep penetration, his blue cheeks tinting a tinge red as well, finding himself strangely aroused by being on the bottom for once. Despite the pain in his rear, his massive member throbbed more, releasing another spurt of precum onto the bed below. Within moments though, he felt the prince's shaft start to pull back, only to thrust forward again, eliciting another groan of mixed pain and pleasure from Iron Will.

"Aahh...that's it, my minotaur pet...nngh...keep squeezing your prince's scepter..." Blueblood panted as he worked up to a steady thrusting, trying to hold himself back from simply pounding the minotaur as hard as he could; the feeling of his sensitive, swollen flare dragging back and forth against those squeezing insides was quickly driving his arousal through the roof. With a bit of concentration, his horn began to glow one last time, working the spell again and beginning to siphon the minotaur's manhood, only further increasing the pleasure for both of them.

With every thrust the prince made, Iron Will could feel those swollen orbs lightly bumping against his own, easily noticing the size difference between them. Blueblood's had to be almost twice as large in comparison, and with his magic, they only seemed to swell even larger. "Mmngh...wh-what the...?" Iron Will's eyes slowly opened again as he swore he felt the huge shaft inside him growing; his insides feeling even tighter around it as it seemed to spread them even further. "Ahh...p-prince...whatever your name is...what's going on back there?"

"Were you...nnh...not paying attention to me when I was, ahh, handling the other males?" Blueblood teased with quite a lustful smirk on his face, continuing to work his magic on the minotaur's member, siphoning its size into his own. His panting became heavier as he had to work harder to thrust; the minotaur's rear becoming tighter and tighter by the second as his shaft elongated and gained even more girth. At the same time, his balls swelled past massive sizes, growing proportionately larger than when he had drained the other stallions; nearly the size of small bowling balls and just a few inches above the comforter.

"Wh-what do you mean?" Iron Will gasped, his eyes opening wide as he felt his snug rear being spread further and further, though as he turned his head to the side, he was able to see Big Macintosh and Thunderlane, along with the miniscule malehoods between their legs. Quickly glancing down between his own musclebound haunches, his eyes widened even further as he watched his own shaft shrinking down with every passing second, while the pain in his rear only grew at the same time."Nngh, what are you DOING TO IRON WILLIE?!"

"Ohhh...mmnh, I must admit, Iron Will...your endowments are quite potent...mngh...I didn't grow this much when absorbing the other stallions!" Blueblood sighed and groaned, feeling his orgasm rapidly approaching with every rough thrust he made. His scepter had to be over three feet in length now, with a monstrous girth to match, roughly pounding the minotaur's abused rear and shooting off gush after gush of sticky pre inside him with each throb it gave. With the siphoning just about completed, his pent-up orbs now rested on the comforter below him, looking like two pearly-white beach balls from how large they were.

Iron Will could only stare in disbelief at his shrunken malehood, now only a few inches in length compared to its previous massive size, though with the surges of pain and pleasure in his rear, it still throbbed with his own imminent climax. "Nngh...Iron Will hopes this is...temporary magic!" he grunted, before leaning his head back and roaring as the prince's rough bucking finally brought him to orgasm. With his tiny size though, his ejaculation only consisted of a few drops of seed; quite miniscule in comparison to the tidal wave that his rear was about to receive.

"Don't you, nngh, worry...Iron Will...you'll be fine!" Blueblood gasped in response, closing his eyes and gritting his teeth as he felt himself teetering on the edge of his own orgasm, that monstrous shaft of his throbbing harder within the minotaur's rear, flooding it with load after load of precum. "Now...take your prince's load!" he growled, making a few more rough thrusts before slamming his hips forward and burying every inch of his overgrown shaft into the snug rear, letting out a blissful, almost passionate moan as he felt his gargantuan testicles contract and begin to force out the oceans of seed they contained.

In an instant, Blueblood's member began to erupt powerfully, gushing seed like a garden hose into Iron Will's insides with such force that it managed to gush up through his insides and to his stomach, filling it quickly and, due to the sheer amount gushing forth, began to quickly bloat and swell the minotaur's belly! Iron Will's chiseled abs soon rounded out as his gut expanded, bloating up bigger and rounder with each passing moment that Blueblood unloaded inside him, his belly button popping outward as well from all of the immense swelling.

The prince was in such ecstasy from his immensely powerful orgasm that he didn't even care to notice the massive bloating he was causing; his eyes shut tightly as he shuddered lightly from the pleasure coursing through his monstrous member, though Iron Will noticed very quickly how his belly was swelling up like a balloon, creating a rather enjoyable warmth within him. "Nngh...wh-what...??" his jaw dropped as he started in disbelief at his own bloating belly, just swelling and expanding with every gush of seed that the prince forced inside him.

"Ooohhh...Sweeet Celestiaaaa..." Blueblood moaned, his own cheeks blushing quite deeply as his orgasm finally began to wane, though his malehood released a few more pumps of seed before his orgasm finally subsided, leaving him quite fatigued. Slowly opening his eyes, he groaned softly from a powerful afterglow which immediately kicked in, leaving him with a slightly light-headed feeling. “Mmnhh...absolutely marvelous…” he softly groaned, looking down at the minotaur below him and smirking a bit, seeing just how large he had bloated Iron Will’s belly.

With the gallons and gallons of seed inside him, Iron Will’s gut had expanded so large that one would think he was heavily pregnant. His rounded belly was pressed against the comforter, leaving him with a look that some would refer to as “musclegut”. All of the internal warmth and swelling had left him quite dazed though; groaning softly with his eyes closed. With a soft sigh, Blueblood finally got up the strength to lift himself up, pressing his hooves against Iron Will’s upper back while pulling his hips back, slowly sliding his engorged shaft from the minotaur’s abused rump.

“Ahh…” Blueblood let out a deep, content sigh as he flopped back onto the huge pillows behind him, while his massive erection flopped against his belly and chest, easily reaching up to his snout, even. With a soft blush, the prince grinned and stroked a hoof up and down his length, gently slurping the tip of it as well. “Mmnh, you all have made your prince very happy.” he teased with a playful smirk towards the three bound males on his bed; Big Macintosh and Thunderlane gazing back at him in awe, amazed at the sheer size of his royal scepter. Iron Will however, was still too dazed from his huge seed injection to even register what the prince had said.

“Seeing how delightfully massive I’ve grown...I might just be keeping your endowments for a little longer than I had expected...”

THE END, I suppose.
