Powerjizz, or how Spike stopped being frustrated and learned to love two Mares

Twilight Sparkle could tell something was up.

She'd been continuing her "magic training" for about two weeks now, and had come to the conclusion that she had steadily been gaining less power as time went by. After running a few tests that confirmed she wasn't building an immunity, the studious unicorn came to the conclusion that her assistant's semen was somehow losing its potency.

Operating on this assumption, Twilight had given her dragon three days off to recuperate. Somewhat annoyinngly, the dragon had spent most of it with Rarity when the purple pony wanted him under observation.

Speaking of Spike, the male in question was walking down the stairs at this very moment, yawning and rubbing sleep from his eyes, still tired from the "Gem Hunting" he did with Rarity yesterday. "Morning Twi." He greeted.

"Good morning Spike!" She replied. "Are you ready to donate some more sperm for science?"

Had the dragon been drinking a liquid, he would have spit it out all over his housemate's face. He wasn't, however, she all that came out was a stammered "Uh, today? Right now? I thought I was on break?"

"Break is over, we need to resume research!" Twilight stated in an annoyed tone while pacing slowly towards Spike. "C'mon Spike, don't be so difficult!"

"B, But Twilight!" Spike replied. "I have to help out Rarity in..."

"RARITY CAN WAIT!" Screamed Twilight, thoroughly annoyed by her assistant's constant obsession with the fashionista. "WE MUST DO SCIENCE!"

At that, Spike started running.

About fifteen minutes later, the library door slid open in a haze of magic. The unicorn everyone was arguing over trotted in. "Oh Spi-IKE!" She called out. "You said you'd be by about twenty minutes ago. Is something the mat..." The sentence hung uncompleted as its speaker was stunned silent.

The book depository was a mess. Furniture was overturned and literature was scattered with reckless abandon. In the middle of the foyer, Twilight had magically pinned Spike to the floor and was licking his nether regions furiously, trying to coax his sweet seed out of Spike's erect penis.

The dragon stopped struggling and the unicorn stopped her attempted rape when they noticed Rarity. Everything fell silent, save for a hubcap falling over in the distance. Rarity stood stunned, mouth wide open in a rather un-ladylike expression, as a crazy looking Twilight released Spike to walk up to her.

"Well well well WELL!" Twilight spat, "Look what the cat dragged in!"

"Twilight dear, what is... What are..." The white unicorn stuttered, not sure what to say.

"Don't try and smooth talk your way out of this one, Miss Rarity.... RARITY!" Exclaimed Twilight, who had totally lost her shit by now. "I know, for a matter of fact, that you!" She pointed a hoof at Rarity accusingly. "Have been sucking!" The lavender unicorn took a step forward. "My dragon's!" The two mares were now inches apart. "DICK!"

After hearing the student's accusations, Rarity became huffy and indignant. "Well... Well what if I have been?" The white unicorn shot back. "You've been passionlessly milking this poor little dragon like some... hormone plagued cow for your own studious benefit. MY lovemaking sessions with Spike have been warm, intimate affairs he can appreciate. You are using him."

"I AM USING HIM?" Twilight raged. "You've known that Spike was in love with you from the begining, and you've been using him ever since!" The purple unicorn retorted. "I bet all you've ever done is suck his dick! If you were interested in anything but his seed, you'd be open to experimentation, you tramp!"

Rarity's eyes got very arrow at this. "Oh, it. Is. ON!" She declared before leaping at Twilight Sparkle, sparking a rolling dust ball of cartoon violence that further disheveled the library.

Spike decided that now would be a good time to leave, and having lost his boner a long time ago, ran out as fast as his stubby legs could carry him.

The fighting continued for several minutes, until Rarity bitchslapped Twilight silly, knocking the lavender pony to the floor. "I'm sorry you had to see me engage in such an un-ladylike activity Spike. We should depart before..." The fashionista began, but stopped when she noticed Spike had left. "...oh dear."

Twilight, who had now recovered from the falcon bitchslap, got up to continue the brawl, but stopped when she too realized Spike had fled in terror. "Rarity, I think we both messed up."

Meanwhile, Spike was resting beneath a tree growing atop a hill. The purple dragon was still huffing and puffing from his frantic run. After a quick rest, he planned on having a nice long talk with the two mares...

"HIYA SPIKE!" Exclaimed Pinkie Pie, who had suddenly popped out of a knoll in the tree.

"Oh, hey there Pinkie." Spike replied in a non-energetic tone. Though he would never get used to the party pony's antics, he had built up a tolerance to her unique weirdness.

"What's the matter Spike? Something brown got yer smile upside down?" Pinkie asked with concern. A face splitting grin then crossed her face. "Well I'm gonna make you feel alllll better!" The party pony exclaimed, then suddenly began rubbing Spike's crotch.

"OK, what's your motive for giving me a blowjob?" Asked Spike as he pulled away quickly. "Is it the key ingredient of some special Cumcake? Or will it somehow make you even MORE hyper?"

"Oh no, nothing like that Spikey-Wikey!" Pinkie replied. "You see, I know all about how you've been banging Twilight AND Rarity- Not bad for someone your age, if I may say so as an experienced partier- because I read Twilight's diary and stalk Rarity then I asked myself why I wasn't getting a slice of this dragon sperm cake so I thought I'd come on down, seduce the best well only dragon I know well enough to consider halving sex with, and then..."

Before the rambling pink pony steer her run on sentence in an even more disturbing direction, Spike, being tired of this bullshit, used his magic fire to teleport Pinkie Pie out of earshot.

Meanwhile, in the royal palace of Canterlot...

The Champion of the Sun, Princess Celestia, is sitting in her royal bedchambers, taking a well deserved break from her royal duties. A pleased smile crossed the monarch's face as she felt the familiar rush of magic that indicated her prized student was sending her a letter. What a rude surprise she was in for.

"...We'd ride each other's mutually orgasaming bodies of into the sunset where we'd..." Pinkie Pie rambled while appearing in mid-air above the Princess, and crushed her majesty with a sugar and fat laden pink body. The princess just rolled her eyes.

"Well, look at that. Another aspiring lunar colonist."

Meanwhile, Twilight and Rarity had caught up to Spike to apologize. "It was wrong of us to exploit you like we did." Twilight explained. "One should value your friends for who they are, not what you can get from them." She stated, summing up the moral of this story.

"Yes, we had dreadfully manipulated you Spike." Rarity added on. "We both understand perfectly if you no longer wish to be our friend, but if there is anything at all we can do to make it up to you, just ask. Your wish is our command."

"Anything?" Spike asked while scratching his chin. The two unicorns nodded. "Well, there is one thing you two could do..."
