“P…punish?” Applejack’s voice was shaking, “Being trapped here with you is punishment enough!”

“How rude!” Trixie replied, “You really should watch that tongue of yours in the presence of The Great and Powerful Trixie.”

Applejack was about to respond, when suddenly she felt the ropes around her front legs slowly being untied by magic.

“Wh… you’re letting me go?” She asked naively, already knowing the answer.

“Oh no, silly farm horse. I just need you in a more suitable position.” Trixie replied. She then levitated a bench from across the room, and placed it underneath Applejack’s stomach.

The bench supported the earth ponies lower half, but left her upper half dangling over the other side. Trixie used the rope to retie Applejacks front hooves to the legs of the bench, and the mare was once again immobile. This time however, she was bent over, with her butt sticking up and facing her capturer.

Applejack suddenly felt her tail being lifted over her back, and became incredibly fearful as her orange ass was put on full display. She blushed, utterly humiliated.

Trixie laughed,

“What did I tell you?” She teased, “You are completely at my mercy.”

For a few seconds, Applejack could do nothing but listen helplessly to the sound of Trixie’s hoof steps. The unicorn trotted over to the bottles in the case on the floor. She slowly lifted each one, admiring them before settling on a pink bottle containing a bubbly liquid. Trixie then made her way back to her victims rump, also taking along the tub of powder, and the brush.

Applejack braced herself for the worst, but for a while, nothing happened. She could hear Trixie muttering, opening one of the bottles, and at times she could even feel the unicorns breathe upon her large cheeks.

The anticipation was killing her, “What... are ya doing back there?” Applejack asked, as she struggled once more.

“Just relax.” Trixie stroked Applejack's right butt cheek gently with her hoof. “I just need to inspect you a little.”

The sensitivity spell was as strong as before, and the slightest touch of Trixie's hoof caused Applejack to moan.

Trixie felt all around Applejack’s arse. She parted the mare’s cheeks, and blew into her crack, which caused Applejack to groan and blush intensely.

Then, Applejack heard another noise; the sound of liquid dripping onto Trixie’s hooves. The unicorn touched Applejacks cheek and began to rub in some lotion, it was pretty cold, but nothing compared to the ice earlier.

“Wh... What is that?” Applejack asked, afraid of the answer.

“It’s a special formula.” Trixie replied, “It will stop you from bruising.”

“Bruising???” Applejack’s heart leapt at that word.

“Yes.” Trixie stroked the mares butt again, rubbing a large amount lotion into her flesh. “You have been a very naughty little pony, and now The Great and Powerful Trixie is going to spank you.”

"Huh?!!"

Applejack tried to kick and move her tail, but it was useless. Her bottom was so sensitive right now, she wouldn't be able to take a spanking.

“No… Trixie…” She pleaded,

“Are you going to beg?” Trixie sniggered.

The stubborn country mare frowned and shook her head.

“Well then.” Replied the unicorn, levitating the tassel whip for the mare to see.

She lightly brushed the soft tassels against Applejacks left butt cheek, then over to her right, and the country mare gave quiet moans. “Are you ready for your punishment?”

Applejack shook her head, “N... no.”

“Very well.” Trixie replied, and continued toying with the mares ass.

“Ohh… urhg… no…ahh!” The country mare tried to resist as the tassels found their way inside her butt crack.

Then, Applejack heard the container of powder being opened. She turned her head and watched helplessly as Trixie dipped the brush inside, allowing it to collect a generous amount of power. Applejack felt her ass cheeks being parted gently, and Trixie lowered the brush between them.

“What is… OOOOOOH!!” Applejack moaned, “no… NO no!”

Trixie brushed slowly up and down Applejack's crack. The powder began fizzing inside her. It stung a little, and caused the mare to try and shake her ass to get away from it.

"AAhh! Make it stop!!" She cried,

“It’s unbearable, isn’t it?” Laughed the unicorn, “It’s made from sour fruit and vinegar, it fizzes none stop, and I have plenty of it.” She shook the bottle, to confirm her statement. “I’ll bet if your ass was free, you’d be shaking it pretty good right now, I’d quite like to see that.” She applied more powder, then stepped back, admiring her prisoners backside.

“Urghh!!! Get it out!!!” Applejack shouted, "Please!!!!"

“As you wish.” Trixie replied, to the country mare's surprise.

Then, Applejack suddenly felt a wet, pointed tongue make its way between her butt cheeks. Trixie was licking out the powder. The touch of her tongue make Applejack shriek; she was so, so sensitive right now.

"Urhhhhggh" She moaned, there was no point trying to hold it in any more.

Trixie licked slowly, lapping all the way up to the mare’s anus, then down the other side, and between her legs. Applejack was relieved of the strange fizzing powder, but Trixie’s tongue was making her feel all sorts of different sensations.

"Uhh... Oooh....uh..."

She continued to groan as the unicorn lapped away.

“My, it sure is… fizzy isn’t it.” Trixie commented, “It's neutralised by water though." She took an ice cube in her mouth, and sucked for a while, then swallowed it along with the powder. She then walked around the bench and looked her victim in the eyes.

“Now are you ready for your punishment?” Trixie asked again,

“Wh…. No I… you mean that wasn’t the…?” Applejack stuttered weakly,

“Tisk tisk, you insult the Great and Powerful Trixie.” The unicorn levitated the container again, and dipped the brush inside, taking a much larger amount of powder than before. Applejack watched in horror, as Trixie held out the brush for her to see.

"Oh no." Applejack started to panic at the thought of her ass being tormented by that horrible substance once more.

The unicorn smiled, then returned to Applejacks backside, held the cheeks open with magic, and began to bring the powder down into her crack. Then, the country mare finally gave in.

“No… stop!!" She took a deep breathe and swallowed her pride, "I… I’m ready… for… mah… punishment.” Applejack bowed her head, submissively.

Trixie grinned. “Good little cowgirl.”

To Applejacks horror, Trixie continued stroking her but cheeks for a while with the tassels on the whip, as though preparing them for what was to come.

Applejack panted, and braced herself for the worst.

Then, Trixie did it.

*Wack*

Right across Applejack’s left cheek.

“Owww!!!” The mare cried out,

*Wack* *Wack*

“OOOOOUCHH!!!”

It hurt more than Applejack had expected, but the pain was so fast and sharp, and it didn't last for more than a second each time.

*Wack* *Wack* Wack*

“Owww!!!”

The mare could do nothing but cry out in pain as Trixie spanked her again and again. Trixie then switched to the other side of the whip, which struck even harder.

“Owww!! Trixie, please no mo….”

*Wack* *Wack* Wack*

“This is what you get for not cooperating with The Great and Powerful Trixie!” The unicorn exclaimed as she hit Applejack harder,

*Wack* *Wack* *Wack*

Tears formed in Applejack’s eyes. Her overly sensitive rump was getting sore, she couldn’t take much more.

*Wack* *Wack*

“Trixie! I’m sorry! Please stop! Please!”

*Wack* *Wack*

“Beg.” Demanded the unicorn.

*Wack* *Wack* *Wack*

“Please. No more!” Applejack obeyed without hesitation this time.

*Wack* *Wack* *Wack*

"Trixie! No! PLEASE! Have mercy!*

*Wack* *Wack*

"Please! No... no more! I can't take it.. I'm... beggin' ya!!!"

Trixie paused for a moment, realising that Applejack was now properly crying. She gave the mares backside a gentle stroke with her hooves, as though trying to sooth it a little. Then, Applejack felt something hard and pointy just above her anus. She snivelled a little, as Trixie's horn circled around and around.

"N...no" The farm mare pleaded exhaustedly.

Trixie continued to tease Applejacks butt hole with her horn.

"Who's been a bad pony?" She asked,

Applejack felt her heart racing, she knew she had to please Trixie, or else the unicorn was going to do something terrible to her.

"I...I've been a bad pony." She said helplessly, "Trixie, please don't..."

"You have." Trixie taunted, "But you're going to be cooperative from now on, aren't you?"

"I...uh...uh..." Applejack was struggling to disguise the fact that Trixie's horn was actually stimulating her.

"If you're not, then The Great and Powerful Trixie will have to punish you again." The unicorn threatened,

"N...No..." Applejack said through moans,

"No what?" Trixie's horn stopped moving, and pressed a little against Applejack's butt hole.

"Urrrghh! No... I... I'll cooperate." Applejack surrendered.

To the earth ponies surprise, Trixie relaxed her horn, and whispered.

"But I won't do that, until you want me to."

"I don't... I won't ever want ya to!" Applejack shouted through tears.

Having Trixie toying with her body and stimulating her was one thing, but being penetrated by any unicorn apart from Rarity was just out of the question. It didn't matter how much Trixie teased her, she would never want that. She would never ask for that.

Trixie actually took the news rather well, “Okay, Okay,… shhh… don’t cry." The unicorn walked around to the front end of her victim. She lifted her hoof, and wiped away one of Applejack's tears.

Then she added, "Trixie doesn't like seeing you upset Applejack. But have no fear... Trixie knows how to cheer you up.”

Applejack's eyes widened as Trixie levitated a large feather and waved it around mockingly in front of her face.

"N...no..." she whimpered. "Not... that."
