"How much farther is it?", Springtrap asked.

"Don't worry, I think we're almost there", I answered. We've been digging for what felt like forever. I figured that the only way to give Rainbow Dash breasts was to find a spell that could make her anthropomorphic. At least, that's my conclusion. However, anthropomorphic spells are very rare in this universe, so finding one is extremely unlikely. It's easier to find a breasts spell, though.

"I think we're here", Springtrap said.

"Oh! Excellent", I said. However, when we dug up to the top, we found Gladmane instead of the Mechanical Monstrosity.

"Hi, Alan. I'm gonna need my property back", Gladmane said.

"What do you mean, 'property'? Rainbow Dash ain't your property anymore!", I shouted. I kicked Gladmane in the face.

"AH! Oh, so you want to do this the hard way, huh?", Gladmane asked. He delivered a powerful punch to my head, knocking me out.

"Attack!", Springtrap shouted. The Twisted Animatronics ran towards the rich pony, but he knocked them out as well.

"How many was that? Weren't there four?", Gladmane asked himself. He knocked out Twisted Bonnie, Twisted Foxy, and Twisted Wolf. Twisted Freddy appeared behind Gladmane, and absorbed him. Twisted Freddy then spit the villain out, finally dead.

"Good work, my creation", Springtrap said. Twisted Bonnie, Twisted Foxy, Twisted Wolf, and I regained consciousness. "Hey, Alan. I think I found something that could transform Rainbow Dash."

"A spell?", I asked.

"I think so. It's in Japanese, though", Springtrap replied.

"Let me see. 'Rainbow Dashを擬人化クリーチャーに変えよう！' (Turn Rainbow Dash into an anthropomorphic creature!) Yep, this is the right spell! Well, that's lucky. Anyways, it doesn't look like the Mechanical Monstrosity is here", I said. The Twisted Animatronics were feasting on the flesh and organs of Gladmane. "Well, at least your minions can eat something. They are incredible. Not even Henry Emily could create these monstrosities. You are a true artist. Anyways, this spell is better than a breasts spell. Now, Rainbow Dash and I can be a couple! I can't wait to try this out on my marefriend." The Twisted Animatronics finished their meal. Twisted Wolf sniffed the piece of paper. "You know you're not a dog, right?"

"He... tends to act like one sometimes. Come on. Let's go home", Springtrap said.

Back at home...

"Okay, here goes. Rainbow Dashを擬人化クリーチャーに変えよう！", I shouted. Rainbow Dash was bathed in light. She grew to my height. Her new form looked very similar to human Rainbow Dash, but there were plenty of differences. Her wings remained, but they noticeably grew larger. It looked like Dashie had the wings of a legendary Pokémon. Her legs and hooves turned into arms, hands, regular legs, and feet, and they looked... muscular, but without the muscle. Her head remained the same. She also had large breasts. Her cup size was ZZZ. "Whoa. I... I can't believe that actually worked", I said in amazement. I hugged my anthropomorphic marefriend.

"Thank you, Alan. I might look different, but at least I look like a human", Dashie said. "Why don't you... taste my breast milk?"

I stared at my marefriend's breasts. "Are you sure? Remember, you're pregnant with triplets", I said.

"Actually, I pregnant with only one filly. I misread the reports I got", Rainbow Dash said.

"Oh. Okay. Well, then... I don't see why not", I said. Rainbow Dash laid down on the bed, and I climbed on top of her. I grabbed her left breast. I put my mouth to her nipple and began to suck on her breast. Rainbow Dash started moaning. Her breast milk was cool to the tounge. I started to moan as her breast milk filled my stomach. I moved on to her other breast, and started to drink. Dashie moaned more than ever, and I moaned as well. Soon enough, my stomach was filled. I kissed my anthropomorphic marefriend on the lips. We embraced tightly. "Oh, Dashie. I love you so damn much", I said.

"I love you too, Alan. Now, let's get some sleep. It's getting late", Dash replied.

"Yeah", I said. Before long, we were both asleep on Rarity's bed. I was clutching Dash's right breast while I slept. Rarity smiled as we slept.

Outside...

"That Mechanical Monstrosity has taken control of my daughter! This is unacceptable! We need to destroy him!", Springtrap shouted. He was with the Equestria Girls and the Twisted Animatronics.

"Well, Alan and my pony/anthropomorphic counterpart are asleep, so we don't exactly have a leader", Human Rainbow Dash said.

"They look adorable when they're together. True love is cute", Rarity said.

"I can send my animal friends to go look for the Mechanical Monstrosity", Fluttershy said.

"Or Rainbow Dash, Fluttershy, and I can do aerial surveillance", Sci-Twi said.

"And while they're in the air, Applejack, Pinkie Pie, Rarity, and I can look for the Mechanical Monstrosity on the ground", Sunset Shimmer said.

"We can use our different powers to fight him", Pinkie Pie said.

"But what if we get killed? Or captured?", Fluttershy asked.

"I can just rope 'em", Applejack said.

"I say we wake Alan up", Springtrap said.

"No, that's not a good idea. He could really hurt his marefriend with the way they're sleeping", Rarity said. Springtrap, the Equestria Girls, and the Twisted Animatronics looked through a window. Rainbow Dash and I were snuggled up next to each other and fast asleep.

"Oh. I see. Those breasts are enormous, though. And, by the looks of it, they're squishy yet firm", Springtrap said.

"I measured them. Her cup size is ZZZ, the largest breast size there is", Rarity said.

"The spell! There was a warning on the back of the piece of paper. It said, '警告：Rainbow Dashの胸サイズはZZZになります。注意して読んでください。' (Warning: Rainbow Dash's breast size will be ZZZ. Read with caution.) Well, I think they're gonna be fine. They look so happy together. I don't want to ruin that", Springtrap said.

"Um, who made that spell?", Sci-Twi asked.

"I don't know, but I think it was some kind of Japanese person. The spell is in Japanese", Springtrap answered.

"Oh, man. They could be in grave danger! Or worse, her breasts might grow beyond that size!", Sci-Twi said.

"Calm down, Twilight. Let's just try and find the Mechanical Monstrosity", Springtrap said.

"Right. Fluttershy, Rainbow Dash, you're with me. Applejack, Pinkie Pie, Rarity, Sunset, you guys have the ground. Springtrap, you and the Twisted Animatronics have the underground. We're going to find the Mechanical Monstrosity and put an end to this once and for all!", Sci-Twi commanded.

"Yeah!", the other humans shouted in unison. The Twisted Animatronics roared. Rainbow Dash, Fluttershy, and Sci-Twi flew off in different directions, Applejack, Pinkie Pie, Rarity, and Sunset ran off into the night in different directions, and Springtrap and the Twisted Animatronics started digging in different directions.
