““ ‘It’ll be fine’ she said. ‘I just need to test this size-changing spell on other living beings’ she said. ‘I already tested it with Rainbow Dash and nothing went wrong’ she said. ‘It can’t affect you that much’ she said.

Why do I always agree to be her test subject? Oh, right, number one assistant and all that. It had happened so fast: a flash of light, I felt my entire body shake, and a moment later: bam! I’m ten centimeters tall.

Well, I think it ain’t so bad. I mean, I’m still in one piece, right? That didn’t stop Twilight from freaking out though. It was pretty fun to watch her go a little nuts trying to figure out how to undo the spell once the reversal-spell didn’t work. I was starting to feel like I would be stuck with this tiny size for a long time (Celestia knows I don’t have any issues or mental scars about being a runt for over twenty years whatsoever). Thankfully, Twilight found how to change me back to normal, but she had to go to the library back in Canterlot to search for and learn the right spell.

And before I could say anything, she teleported away leaving me alone in the castle. With nothing else to do, and not daring to move away from the Cutie Map, I sat away from the edge waiting for Twilight’s return.

“This day can’t get any worse.” I muttered after about twenty minutes of silent waiting. “How come my voice sounds the same? I thought it would sound squeaky like in those movies and comics.”

A sudden creak caught my attention followed by the doors of the castle being opened.

“Yoo-hoo~ Sorry for the intrusion!”

I had to jinx it, didn’t I? I thought hearing the voice of my marefriend. I could hear her steps coming approaching as she did. I thought about hiding, but why bother? With my current size I couldn’t get away fast enough, and me being on top of the Cutie Map meant I couldn’t get away even if I wanted to.

“Twilight, Spike, are you here?” I heard Rarity ask as she entered the council room.

She stopped when she saw me and I sighed.

“Hi, Rarity.” I called waving my tiny arm. She stared at me for who know how long, barely blinking and making me feel more uncomfortable than I already was.

“Spike? Is that….you?” She asked while she walked up to me.

“Yeah, it’s me.” I scratched the back of my head trying, and failing, to not stare at her. When I was still small, her towering stature over me always made me feel so insignificant, and, well, small. But I also couldn’t help to stare at her feminine and curvaceous figure. Much like I was doing now, although her features, only seemed to be more, ehem, ‘prominent’ with my current size. “I can explain.”

“Twilight?” Rarity, now standing in front of me, said with a deadpan expression.

“Twilight.” I replied shifting on my spot. Try and I may, I couldn’t stop staring at her long, slender legs now the width and size of the most beautiful and oldest oak trees in the forest. Her hourglass figure carved from rigorous diets, exercise, and her demanding work now resembling a carved marvel of the ancients. Especially with that mid-thigh level black skirt and the toga-like blouse she favoured on her off-days.

Her face, always radiant and clean (like the rest of her body. Believe me, I know.), was adorned with a faint blush while her blue eyes sparkled looking at me with interest. Her lips, so soft and tender, covered by a thin layer of purple lipstick. I gulped when I saw those same lips curl into a knowing and playful smile.

“Goodness gracious, darling. How fortunate I came to visit then! Why, I don’t want to think of what could ever happen to you in your current predicament without a watchful eye looking for your safety!” She said with an overly cloying tone that made my face heat up with a blush.

I knew she was playing around. No way she was going to let this chance pass up.

What I did not expect, however, was that she would lean down for a close up.

“You look rather adorable, Spikey.” She said making me gulp down, hard. But I couldn’t bring myself to look at her face. I was too distracted by two enormous mounds of flesh held firmly by her blouse. A giant pair of white breasts showing a cleavage that could only belong to a goddess.

“What’s the matter, Spikey? Your face is quite red.” Fuck, she knew I was looking at her tits. I saw her lips curled into a rather sexy and playful form, almost like she was pouting but not quite.

“I-uhmm- I think the air is a bit chilly down here.” I said trying to play along. I hear her humm while tilting her her to the side a little.

“That’s no good, dearest. You might catch a cold if I don’t do anything. And we don’t want that, do we?” She licked her upper lip.

Can’t broken, work doesn’t brain.

Before I know it I’m nestled in between the valley of my marefriend’s breasts.

Twilight just earned herself a month’s worth of breakfast in bed.””
