The Whole Thing
Pinkie sat in a field of lust as she sat impatiently on the cold tile floor. She squirmed as her chastity cage twitched. Moaning quietly, Pinkie looked down at it, seeing another twitch. It called to her, begging for a release, or even just a touch. Just a teeny tiny tap on the tip of it would do.
It hadn’t been long, but she was impatient. Two days was far too long for her. She needed to cum so badly, but she couldn’t with the plastic cage around her cock. Maybe a vibrator could get her off. It probably would, but where would she get one?
Twilight locked all of those up in a cabinet. The cabinet wasn’t even in her room. It was in Twilight’s. And it wasn’t like she could pick the lock. She didn’t know how! She could steal the key, but Twilight was the only pony who knew where it was.
Maybe she could emulate a vibrator. If she shook the cage hard enough like the vibrators did, maybe…
“Na-ah-ah,” an authoritative, but sweet voice warned. Pinkie pulled her hoof back again, moving it off the stiff plastic cage. “No touching!”
“S-Sorry, mommy,” Pinkie mumbled. “I didn’t mean to-”
“I know, my little filly, I know,” Twilight cooed. “You don’t need to feel bad. Instinct kicked in, that’s all. It’s just lucky I was here to stop you from playing with it. Don’t want my filly to cum without permission, do we?”
“No…”
“Good filly.” Twilight looked down at her with a seductive smile, causing her to twitch again.
Giggling, Twilight moved her hoof down to the plastic cage covering Pinkie’s cock, giving it a tiny flick. She moved her hoof upward, stroking Pinkie’s frizzy mane slowly. “No cummies today, little one. Maybe in a few more days. Maybe.” Twilight, moving her hoof away, pecked Pinkie on the forehead.
Yet another twitch came as Pinkie looked up at her mommy, her eyes clouded with arousal. Practically foaming at the mouth, Pinkie replied, “Okay, mommy,” her voice showing her disappointment.
“Good. Now, mommy has to go to a very important meeting in Canterlot, so she won’t be here tonight. Up, please.”
Obeying, Pinkie stood up, shaking from being so pent up. Twilight offered a hoof, so she accepted it, and allowed her mommy to guide her across the room, stopping at a hoof-made bondage table, with drawers below. She blushed in response.
“Hop up on the table, sweetie,” Twilight instructed. Pinkie complied, and Twilight explained, “I know, you’re a big girl, but you’ve been going potty a lot at night lately, and I need you to stay in your bed tonight. Mommy’s gonna put you in a diaper, okay?”
Though Pinkie whined in objection, Twilight opened one of the drawers, pulling out Pinkie’s two options with her magic aura. “Would you prefer plastic or cloth?”
Pinkie’s bladder was going to break soon. She didn’t like to pee in her cloth diapers, so she replied, “…Plastic.”
Putting the cloth diaper back in, Twilight lifted Pinkie’s hindlegs, slipping the diaper beneath her. Using her magic, she then levitated over some baby powder, giving a light sprinkle over Pinkie’s privates. “There, there. I know it’s embarrassing, but it’ll be over soon. Mommy promises.”
Pulling Pinkie’s hindlegs apart, Twilight folded the plastic diaper onto Pinkie. One by one, Twilight attached the tapes on the front, until the diaper sealed adequately. “Turn around, please,” she asked.
Pinkie turned, and Twilight threaded Pinkie’s tail through the tail hole, applying the last tape after that. To finish the change, Twilight levitated over a pair of light pink plastic pants, sliding them over the diaper. “Good filly,” Twilight commented, pecking Pinkie on the forehead again. “Does my little filly want to sleep in just her diaper, or would she prefer a onesie?”
Seeing it was midsummer, Pinkie softly answered, “Just the diaper, please.”
Nodding, Twilight wrapped her forelegs around Pinkie, pulling her into a tight hug. “I love you, sweetie!” She guided Pinkie’s head towards hers, leaning in for a kiss. The two locked lips and gave a long, passionate kiss.
Moving back, Twilight levitated Pinkie onto her back. Pinkie giggled at her. She wasn’t very strong, so it was always a struggle to carry the mare. Despite this, she always tried to make it look effortless.
Pinkie sitting on her back, Twilight began struggling towards a bed surrounded by giant bars. Initially, it was supposed to be a crib for adults, but it looked more like a pony-sized cage.
Unlatching the front and swinging the door of the ‘crib’ open, Twilight set Pinkie down in it, planting one last kiss on the forehead. She closed the door and immediately levitated over some restraints. “Just insurance,” Twilight explained.
Four soft cuffs were latched onto Pinkie’s legs. Each was tightened enough for her not to be able to slip out, but not tight enough to cut off blood flow. Once attached, Twilight clamped the restraints to the bed, causing her limbs to splay across the mattress.
A soft blanket levitated over Pinkie, and the lights in the room flipped off, leaving only the light from the covered-up window to brighten the room. “Alright then, sweetie. Sleep well! I’ll be back in the morning.”
Twilight blew a kiss and walked out of sight, the door clicking shut behind her. Pinkie was alone again, now wearing a rather embarrassing outfit. She sighed.
Clenching her eyes shut, she released her bladder. She blushed as the diaper became warm. The damp diaper licked her body, causing her to squirm in her restraints. She wasn’t tired, and she so desperately wanted to cum. She rocked up and down, humping the air in frustration. She moaned, whispering, “Celestia help me,” under her breath. “How am I going to get any sleep?”
Slowly, however, she began to feel her mind drift off, her eyes becoming tired of the unchanging view. Her breath slowed, her squirming stopped, and her lids became heavy.
Finally, she closed her eyes, and her conscious drifted in and out until she fell asleep.
