Twilight Sparkle was bored. And frustrated. And third emotion conveying dissatisfaction. Her quality of life had entered into a downward spiral, and while she could point to any number of problems behind that trend, a good chunk of it was a good old-fashioned inability to hit orgasm.

It wasn’t for lack of trying — she had more toys now than she knew what to do with — so much as it was the lack of imagination. She needed to fantasize! Something to get her primed and ready. The time had long passed when she could masturbate to a cheap smut rag. She’d read every saucy novel in the library now. The dominating escapades of Mistress Topspin and poor Bottom Line, hot as they were, simply didn’t cut it anymore. Perils of a photographic memory.

“Uuuuuugh.” She rolled herself up in her sheets, trying to smother her own burning need. She brushed a couple fingers over her soaking panties, trying to let off a little heat, but that only served to stoke the flames. “I know life’s a ride, but I wanna get off now.”

A crash rang out from downstairs and her mind flickered to Spike. “Ugh, no!” she grumbled into her pillow. Not Spike. He’d grown a lot as of late, and was most certainly an eligible bachelor, but she couldn’t even look at him right now. He’d gotten all sorts of obnoxious and rebellious after reaching eighteen. Never doing chores, eying all the female visitors, and even folding pages in books! Sexually frustrated as she was, Spike was causing her too much regular frustration to even consider.

Another crash downstairs. She looked up from her pillow. “Speaking of Spike...” What exactly was he doing down there? Time to go check on him. She magicked the blanket off her and shuffled grumpily toward the door. So help her, if Spike was doing anything destructive down there, she’d find herself with plenty of dragonskin for her potions.

Wait. Her eyes snapped open. “The potions!” She shot down the stairs as fast as her feet would take her, wings fluttering anxiously behind her back. “No, no, no — oh, nooooo.” She crumpled to her knees when she saw the mess. Spike had gotten into the potions. Beakers lay broken on the desks, the shards dripping with beyond-precious contents. Her research manual had a hole burnt in it and her notes were soaked beyond belief.  

Then sorrow turned to outrage. “As soon as I get my hands on the dragon, I’ll...” She looked around. “Where is that dragon?” There seemed to be no sign of him in the foyer, and she hadn’t heard the door open, so he had to be in the room. Where, though? It wasn’t exactly easy to hide six feet of scaly purple lizard. She should have seen him by now...

Her ears twitched as they caught a skritch-skritch-skritching sound. Just by her feet, beneath the desk. She groaned. Mice in the library? That was all she needed now. She bent down to check for any scurrying vermin, and found... “Well, what do you know?” she said, a grin spreading slowly over her face. “Scurrying vermin.”

“Twilight!” Spike squeaked. “Thank goodness you found me!”

“Thank goodness indeed,” she murmured, scooping the tiny dragon up. “Looks like you drank my shrinking potion.”

“I didn’t know!” He shouted, standing up in her hand. He was roughly the height of her palm now, which made him the perfect height for punishing. Six-foot-tall Spike never seemed to hear when she lectured him, but maybe six-inch-tall Spike would listen a little better. “I was thirsty and thought you were making a new flavor of Colta Cola.”

Twilight narrowed her eyes. “After I told you not to touch any of the potions on that desk.”

“Well, I might’ve tuned you out. Didn’t think it was that important.” He shrugged his little shoulders, then looked down at himself. “Did you mention anything about how long the potion lasts? I think I was an inch taller a minute ago.”

“It might be an interaction effect with the other potions you knocked over,” Twilight said through gritted teeth. She was just about ready to squeeze him and shout him into a pulp for what he’d done. But then a bright spark lit a bulb in her brain, and she got an awful, evil, incredible idea for teaching Spike a lesson. She grinned her nastiest grin. “I think you’ll be getting smaller for a while yet, Spike, so we should get on your punishment quickly.”  

“Aw, but Twilight, I didn’t—”

“No buts,” she told him, magicking away the clutter on her desk. Every last beaker-shard and puddle of potion. Her research was beyond saving, but the desk could still be useful. Very useful. She set him down on the surface and pulled her shirt over her head. “I’m going to be honest with you, Spike, I’ve been feeling pretty needy today. I’m sure you’ve been listening to me whenever I talk about how important efficiency is, so we’re going to kill two birds with one stone.

“W-which two birds?” Spike stuttered, shuffling back as she unclasped her bra, and practically scrambling as she set her breasts on the cool wooden surface. “Those two birds?”

“Maybe,” Twilight giggled. She’d never admit it to anyone, but she was more than a little proud of her assets. They’d always been big (and sensitive!) for a mare her size, and had only gotten bigger after her ascension to alicornhood — firm and full mounds that sat a teensy bit over a handful. Sure, the extra back pain was terrible, but she had spells to handle that. The stares, though, were priceless.

And Spike’s staring was beyond priceless. He gaped and gawked at her bare naked chest, pressed just slightly into the desk. Slowly he mustered the courage to approach it, and she couldn’t help but notice that he stood just chest-height to her swollen nipples. He was definitely getting smaller. So tiny that she could practically do anything with him. She bit her lip to stifle a moan as her mind raced over the possibilities.

She’d finally found her fantasy.

“We’re going to play a game,” she told him, giving her chest a little pat. She slipped a hand down toward her sopping panties — not like Spike could see what was going on beneath the desk. “I’m going to drop you under one of my, ah... my breasts, and you’ll have to get out in under five minutes. If you win, I’ll forgive you for messing with my potions, and I’ll work on something that can grow you back ASAP.”

“Uh...” Spike took a second to keep staring, the blush evident on his cheeks and between his legs. He seemed entranced, or maybe intimidated, by a nipple the size of his head. “And if I lose?”

“Then we’ll, um, play another game,” said Twilight. She flushed as her fingers worked her up from down below. Luckily for her that Spike wasn’t staring at her face. “And we’ll play until you win. Sound fair?”

“I guess so,” he said. Then a glint sparked in his eye and a cheeky grin spread over his face. “Wait, no. I think you need to sweeten the pot. He gestured toward her tall-as-him tits. “It’s only fair, right? The odds are kinda stacked against me. So how about this: If I win, you also have to do whatever I say for the rest of the week. Like doing all of my chores for me, promising to stop nagging, and calling me Lord Amazing Spike.”

“Fine,” Twilight grumbled. If ever she’d had a doubt about what she was putting Spike through, those had all evaporated. It was clear now that Spike needed to be taught some manners. “We have a deal?”

“Deal.” Spike grinned harder. “Prepare to call me Lord Amazing Spike.”

Twilight snorted. “As if!” She lifted up a ponderous tit, brushing a finger slowly over her nipple. Dear Celestia that felt good. She could only imagine how electric it’d be with Spike trapped under there. He wasn’t getting out from that. She’d make sure of it.

Spike strutted confidently under her shadow. “You ready to lose?” came his squeaky voice.

“Pretty sure I'm ready!” She laughed and let go of her breast, and a veritable wave of flesh fell on her little dragon. “Are you?” Next Chapter: The Mountain Estimated time remaining: 16 Minutes
