The Art of Seduction

Twilight gulped and looked between the two mares hugging closely to his body. Finally, after a moment's deliberation, he shook his mane and decided.

“I’ll go with you tonight Rarity, after all that wine I could go for some lighter fare.

“An excellent choice if I do so say myself,” said Rarity, flashing Applejack her absolutely smuggest smile.

Applejacks cheeks turned crimson. “That’s just plain fine, I reckon. Have a good night. Glad we had a nice dinner and all.”

With that, Applejack turned tail and marched towards Sweet Apple Acres.

“Gee, I hope she’s not upset or anything…” Twilight rubbed the back of his head.

“Oh my stars, darling, please! We had a wonderful evening together I very much doubt she’s upset. If she really wanted tea and mints she could have joined us.”

Twilight bit his lip. “I suppose you’re right.”

“Now let’s head to my boutique!”

The walk to Canterlot Boutique was short compared to the farm and the two ponies made it there in no time at all. Twilight had grown so tall that he found it necessary to duck in order to enter the store. Upstairs, Rarity quickly set up a small table with mints and chocolate treats to pick at. As she set up the pot of boiling water (with the whistler!) she glanced back at Twilight sitting uncomfortably at the table with his hooves in his lap. She had to chuckle at how comically large Twilight was compared to… practically everything else.

“Well darling, I must say I’m absolutely dying to know what it is you’ve been writing about in your logbook?” Rarity said as she approached with some napkins. “You’ve been jotting things down in it even during dinner!”

“I know. I uh, I need to. For research when the spell wears off sometime tomorrow,” Twilight dodging the question.

“Well, do tell! Am I on those pages somewhere?” Rarity giggled lightly and popped a cherry chocolate in her mouth, resting her chin on her hooves and looking up at Twilight. The smell emanating off of him was divine. It was making her brain simmer and her body warm. An idle thought of somehow making this a branded cologne floated through Rarity’s head as Twilight began to yammer on about her writings. To think she was technically entertaining a handsome Prince in her own home!

“-and once the spell effects finalize I’d know their effects but I am starting to wonder if perhaps myself as a test subject was a mistake since as you know I am a male alicorn and there are no male alicorns, and perhaps for good reason because my brain is, just,” Twilight paused, his face a bit red. Rarity noticed he was sweating.

“Go on, dear,” Rarity purred.

“My libido, has been growing all night, and mid way through dinner it skyrocketed,” Twilight gulped, wiping her forehead with a napkin. “I’ve spent the last hour thinking about… sex. Breeding. Mating. Rutting. Rutting mares. Rutting lots of mares. A whole herd of mares.”

Rarity said nothing, her eyes half lidded as she quietly unwrapped another chocolate and popped it into her mouth.

“I… I don’t know if this… overwhelming desire inside of me to copulate is hardwired into the male alicorn mindset or if normal stallions are always horny and not used to it, but, I’m inclined to think it’s the latter, Rarity,” Twilight continued, fidgeting in his seat. “Perhaps natural alicornism is so rare that the male kept herds of mares beneath him and bred with them all in the hopes of producing one? Maybe the trait is sex-linked? Maybe not? These are actually things I should be writing down but I haven’t because all I can think about is mating with a mare!” Twilight practically shouted. After getting all that off his chest he cleared his throat. ”.... the spell happens in stages, and the last swell of magic to top off the spell should be happening any second.”

Rarity batted her eyes and smiled.

“Well, darling, that makes a lot of sense, but you still haven’t answered my question.”

Twilight blinked hard. “What was your question?”

“Have you written about me in those pages tonight?”

Before Rarity got an answer a lavender streak of magic erupted from the tip of his horn and rapidly snaked its way around Twilight’s body.The magic intensified in brightness then settled into his coat.

His body grew even larger in size and strength. His limbs lengthened and strengthened, growing Twilight to a height that now certainly matched Princess Celestia. His wings flared out and shook as they enlarged with his body. The muscles on his body rippled and flexed as they swelled larger and stronger, defined and cut under his purple coat. Twilight removed his hooves and groaned from the magical sensation of the spell, and the massive black obelisk of a cock he’d been holding down and hiding under the table lurched forward and stood straight up, bobbing and leaking a small stream of pre down the shaft to his fat, volleyball sized sack. The table was thrown aside by the growth and release of his organ, the items atop it clattering to the floor.

Rarity sat back with her wide eyes at the now enormous, powerful virile male stallion before her. Twice her size, certainly many times more powerful physically and mentally, just sitting down Twilight was double her height and that jet black organ bobbing oh so enticingly above her had to be almost as long as she was. Her pussy clenched in anticipation. It was so big!

The spell stopped. Twilight let out a soft moan.” Ahh, I feel much better… like having a headache go away.” Twilight panted, lowering his head. He looked down at Rarity with a glint in his eyes. “Now… we, uh, oh. Your question.”

Twilight slowly stroked his mighty cock with his hoof. He was so big now that there was no point to concealing it. With his body he shouldn’t feel that he’d need to conceal it.

“I have written about you in my logbook,” he rumbled, his deep purple eyes studying the tiny mare gawking up at him. “It’s true. I’ve written back and forths about you and AJ, but mostly you. How beautiful you look tonight. How much I enjoyed your occasional gently touch by my side. The different ways I would mate with you. How much of myself I could fit down your throat,” Twilight paused, his cock flexing and oozing out another glob of pre. “Honestly, writing all that down wasn’t helping, but telling you now is.”

Rarity gulped at the thought of swallowing Twilight’s massive tool. “I, ah, suppose I have been quite, transparent with my attitude towards you tonight, Twilight. I must say that… as a mare, that until tonight I have never been quite as physically attracted to a stallion as you my whole life.”

Rarity got to her hooves and slowly walked over to Twilight. The musk exuding from his body was an intoxicating ambrosia now. She sucked it in eagerly, and realized her mouth was watering. “I…” she caught herself trying to speak to Twilight’s dick and looked up at the huge stallion. “I want to…”

Twilight pounced on Rarity, no pretense of talking dirty or foreplay necessary. Rarity yelped in surprise as she was knocked backwards and then silenced as Twilight locked lips with hers for some kissing. His big, sexy, body engulfed her vision and she was like a helpless little filly compared to this stallion ravishing her. Rarity moaned and felt her pussy wink while they made out; his big tongue swirling around and suckling hers. Fat droplets of precum pattered on her coat in wild patterns as they kissed. The burning need in her pussy was rapidly fanning into a blaze.

Twilight abruptly broke their kis and stood up. He towered over Rarity lying prone on her back. Her view was dominated by the hard, fat cock that was sandwiched between them during their make out session.

“I want you to take it,” Twilight urged, magically standing Rarity up on her hooves. “As much as you possibly can.”

Rarity was literally eye to face with the drooling black flare, so long it poked just beneath his muscled chest. So large it was comparable to one of the tea saucers that had been laid out on the table. Rarity was drooling, and the tip of Twilights cock drooled right back.

“I’ll… I’ll do my best, Twilight,” Rarity approached the enormous flat cockhead and licked it a few times, lapping up the salty, colorless fluid dripping out. She opened her mouth and to her great shock found that she could in fact fit it into her mouth! The edges grazed against her teeth but it took one small step forwards for it to hit the back of her throat.

“Gck!” She snorted heavily out of her nose. Even more of Twilights member was in her throat now and she was slowly disappearing under his powerful body. Rarity idly registered her hairbun compressing under his coat and a few strands coming apart and sticking to her sweaty face. There was so much cock in the back of her throat she could barely think about much else.

Twilight placed a hoof almost as big as her rear against her rump and pushed Rarity underneath even more. Rarity felt her jaw start to hurt and there were tears in her eyes as several more inches of cock forced itself halfway down her throat. She was choking on dick. Being absolutely used by this massive stallion. Her eyes refocused momentarily only to be filled with the sight of the two tightly packed orbs dangling in her way, churning and swinging with untold amounts of hot stallion seed. Rarity moaned loudly at the the thought of them slapping against her ass later.

“Yesss, do that again pleease,” Twilight crooned above her, gently pressing and kneading Rarity’s ass with his big hoof.

Rarity obliged, somehow able to swallow three quarters of Twilights impossibly huge cock. Her nose was bumped against the fat medial ring encircling the shaft and she could go no more, instead moaning and humming alternately. There was little fresh air pressed right up against Twilight’s belly and ring like this. Just stifling, warm musk. Rarity breathed in and out of her nose in short quick bursts just to get enough air to breathe.

The stimulation and warm wetness of Rarity’s mouth was enough to put Twilight over the edge. Rarity watched his balls tighten and his shaft surge wider. She swore she felt her jaw audibly creak as the odd sensation of Twilights orgasm travelled through her mouth and started pumping all the way down her throat into her belly.

Rarity couldn’t help but count. Twilight’s body shook as each fat surge of cum piped down into her gullet. By the fifth spurt she was full, and by the tenth spurt she could feel her black dress tightening.. When the fourteenth load of cum finally unloaded her belly was distended beneath her. Rarity cupped a hoof around her tummy; it felt tight like a drum

Mercifully, Twilight stepped backwards and pulled his rock hard cock out of Rarity’s mouth. Rarity gagged and fell back on her ass. Her belly was like a basketball firmly seated between her legs. The dress stretched across it was struggling to contain her now. It made her appear several months pregnant.

Twilight was above her immediately. His jet black obelisk of a cock swayed above her like a python searching for a bite. Rarity laid backwards and spread her legs. She was going to lay with a Prince! This was one of her fantasies since she was a filly. Prince Blueblood may have been a lost cause in the end despite her best efforts. She could kick this off her bucket list.

“Take me, my Prince!” Rarity cried out.

Twilight picked Rarity’s back end up with his magic and immediately took up that offer, sliding as much of his eager cock inside as he could muster with one powerful thrust.

Rarity almost bit her tongue when she shrieked. The dick inside of her right now was massive. It felt like she being split in two by the sheer girth of the hot pulsing rod. Rarity spread her legs as far as they could go just to ease the pressure. It even hurt just a little.

“Agh!” Rarity managed to breathe again. She looked up and saw nothing but Twilight’s powerful chest and legs. “Twilight…. not so rou-!”

A mighty thrust from Twilight cut her plea short. Then another came quickly after that. The another. Twilight immediately found a semi-comfortable, hard, fast rhythm to fuck Rarity in and was focusing on exactly that. Rarity was tight and wet and hot and every thrust she made an adorable high pitched squeak that was like music to his ears. Twilight was in heaven.

Rarity, however, was in sex purgatory. Her brain was swimming with conflicting emotion and sensation. The sex felt good, and it also hurt. She was incredibly wet and aroused, but uncomfortable from being rutted on her back on the floor. Every single powerful thrust was hitting her clit, and also jostling her cum bloated belly. Either she was going to cum or throw up from the rutting she was receiving, and it was starting to feel like the former.

Without warning Rarity felt Twilight’s cock leave her and not return. The empty feeling after having been filled so thoroughly made Rarity whimper briefly. She refocused her eyes to see what was going on when Twilight’s purple magic grabbed her, flipped her over, and placed her back down on the floor. Then the magic pulled her rear into the air and held it firm. Before Rarity could offer any form of protest that gigantic rod slid itself right back into her depths.

“Much better,” groaned a very satisfied Twilight above, resuming his fucking with even more speed and strength behind his thrusts.

Rarity was exhausted. All she could do now was sit there and take the abuse on her ass. Each stroke of Twilights meaty tool through her poor pussy reached all the way down to her womb. Her clit was being bumped by the fat medial ring encircling Twilight's cock every time now and pounding the small unicorn ever closer to orgasm.

This wasn’t like her books. Where were the gentle caresses of the strong prince? The strong, but careful kissing and tender touches? The rewarding but controlled sex where both parties reciprocated enjoyment and pronounced their love for each other during orgasm? Rarity felt like a cheap whore being used for carnal enjoyment alone.

A particularly strong thrust from Twilight knocked Rarity’s hairbun completely loose and her sweaty bangs glued themselves to her face. She possibly looked the part now too.

Twilight sped up his thrusts and crouched a bit lower atop Rarity, his pounding become more erratic and uneven. Sweat dripped off his legs and chest onto the floor. Some of it even pattered on Rarity below. Twilight’s balls tightened and his shaft surged and he paused his frenetic fucking to unload into Rarity once more.

Rarity moaned and writhed in pleasure from her own orgasm being set off. She could feel every pulsing vein and powerful lurch as jet after jet of hot cum was blasted into her womb and filling her up nearly just as much as before. Some of it managed to even spill out of her pussy and dribble down her raw battered ass. She could feel her belly stretch and expand even further; big fat tears ripped through her sheer black dress and exposed the white fur of her beachball sized belly.

After what seemed like ages (Rarity couldn’t keep count this time) Twilight seemed to finally stop cumming. He removed himself with one swift pull and a waterfall of jizz spilled out from Rarity’s gaping pussy. The magic used to prop Rarity’s ass in the air also dissipated and her rear slumped to the floor.

“Ahhh,” sighed Twilight contentedly. He stepped over Rarity and grabbed one of her folded blankets with his teeth, then dropped it on the floor in front of Rarity and himself. Twilight folded his legs and sidled up next to the small unicorn, resting his head on the blanket and draping one his impressive wings over her much smaller form. She was covered wholly and Twilight yawned, then fell asleep a minute later.

Battered, raw, exhausted and stuffed with cum from almost every hole, Rarity snuggled up against the massive stallion who’d fucked her silly. She’d made it with a prince. Real royalty. The mare most desired. She wiped the sweaty bangs from her face and rested her chin on the blanket Twilight provided. Her backside stung and felt cool from the load of cum pouring down her asscheeks. The fancy dress she wore was torn in several places by her expanded gut.

As Rarity drifted off to sleep, she felt little pride in her victory over Applejack.
