Her resolve not to masturbate over the memory lasted five days before she finally gave in. Applejack had come by that morning to talk, and Twilight had spent the whole day trying not to think about the possibilities. Lying alone in bed at the end of the day, it was too much for her.

It didn't matter, she reassured herself. Just as long as she didn't do anything about it. A day later, she began to argue with herself - was it as bad as it seemed? Applejack seemed to enjoy it. Even though she was made to. She should, at the very least, check that the barrier she'd put in her memory was holding. Yes, that was an entirely reasonable reason to have Applejack blankly thoughtless in front of her again.

She couldn't possibly go and drag Applejack to her home again. That would be suspicious. But she had been calling by frequently lately. Twilight could wait.

She definitely could.

It took two more days. Each knock at the door jerked her up onto her feet, only for her to have to cover her disappointment and act as natural as possible. Fortunately she dissuaded Pinkie from throwing a 'Cheer up Twilight it's okay you can't do a spell' party, though with considerable effort. Finally, Applejack knocked at the door, and Twilight couldn't welcome her in fast enough.

The small talk crawled, as she quietly wrestled with herself.

"Well, Ah'm mighty glad to hear that Spike's doing okay. When are you expecting his next letter?"

"Five days, if he keeps to the schedule. I'm very proud that he's travelling so far on his own," Twilight said with a smile, her pride eclipsing her tension for a moment.

"Ah am too. Sure he'll have a lot of stories to tell when he gets back." Applejack paused, then coughed. "See here, Twilight. Everypony's plumb worried about the way you've been winding yourself up lately. Not a one of us hasn't seen it. Ah'm asking you to give that book a rest for a while. No point working yourself into knots over it."

"You're right, Applejack. I'm just really excited by what I'm discovering. I'm sorry if I've worried everypony," Twilight replied gently.

Applejack sighed with relief. "Don't mind telling you I'm right glad to hear that. Been worrying me."

Twilight pressed her lips together. "Applejack?"

"Yep?"

"Would you awaken please?"

Applejack's arms dropped limply onto the chair rests with a double thud, and Twilight unconsciously squeezed her thighs together.

"Ah am awakened."

"A-Applejack. I want to ask you about your last visit but one. Do you remember anything - unusual about it?" The quill floated nearby, her notes picking themselves up. She wasn't sure how the memory block worked.

"Ah am not permitted to remember that visit," the mesmerised pony replied.

Twilight bit her lip. 'Focused Applejack remembers that her memory has been altered, but not the contents of the block,' she wrote carefully. "Applejack, you will now remember what happened."

"Ah remember what happened."

"What do you remember?"

"Ah was awakened and made obedient as a friend. I stood on my head. I was awakened and made to feel good when I obeyed, that only you mattered. I brought you a glass of juice, watched you get off, and was made to forget," she blankly recited.

Twilight leaned forward, her heart accelerating as she listened. "How did you react to being made to feel good when doing as you were told?"

"Ah felt horny. I loved it. It was everything I'd fantasised about."

Twilight blinked, brought up short. "Fantasised about?"

"Yes."

"No, I mean - Applejack, have you fantasised about being somepony's obedient toy?" Her cheeks flushed darker at the very question.

"Yes, Ah have."

She leaned closer, feeling a tingle sweep up her back and prickle on her skin. "Tell me about this fantasy, please."

"Ah think about being brought to heel. Tied up, made to do work, being used f'r anything," Applejack answered matter of factly.

"Who's doing it to you?" Twilight asked softly.

"Some stallion Ah don't know, usually. Doesn't matter so much."

"No mares then? No pony you know?" she prompted.

"Naw," Applejack replied simply, oblivious to the look of hurt and frustration on Twilight's face.

Twilight released a controlled breath. "Have you ever done anything about these fantasies, Applejack?" Now she was filled with a different tension, a pre-emptive jealousy.

"Ah have tied myself up and got off several times."

Twilight relaxed, then began to think, formulating her words carefully. "Applejack. You're now obedient to me, feeling good when you do as I tell you, and I'm the most important pony in your life. Just like before. You'll remember the last time, and it won't matter to you at all that you didn't remember it in between, and didn't feel the same compulsion. You're just happy that you are under that spell again."

Applejack sighed, relaxing slightly. "Ah am obedient to you, you're the most important pony to me. Ah remember last time; doesn't matter that I didn't remember it before. I'm happy to be under your spell."

Twilight paused to think, but couldn't find any obvious holes in Applejack's instructions. With bated breath, she murmured diffidently, "Slumber please."

Applejack's eyes flickered, and she focused on Twilight again with a growing look of adoration. "...Twilight. You put a spell on me to make me obey you?"

Twilight's breath caught. She hadn't meant to make her aware of that. It took several seconds before she found enough of her voice to mumble, "Yes."

Applejack slid out of her chair to the ground, her bare knees hitting the floorboards, and looked up at Twilight with shining eyes. "Thank you, Ma'am. Ah love being forced to obey, Ma'am. I hope this time you'll let me show you jest how much I want to serve you."

Twilight's body flushed with heat and her tongue flickered over her lips. "I - what do you -" she breathed, before she caught herself and said firmly, "Tell me how you'd show me."

Applejack's hips jerked slightly at the direct command, before she answered huskily, "Ah want to strip down for you, Ma'am. Be commanded to, be given no choice. I want to be forced to get off in front of you."

Twilight flushed. Her chest rose and fell quickly under her loose jumper, which now felt far too hot. "Applejack. Take off your shirt now."

The kneeling pony groaned. "Yes, Ma'am. Anything you say, Ma'am." Her hands rose to her checked shirt and she rapidly began to undo it, exposing a widening slice of her cleavage. Slowing as she reached the bottom, she tilted her head and leaned forward a little.

Sliding her shirt down her arms she exposed her bra - a darker green this time - cupping her medium sized breasts firmly. Her green eyes shining, she breathed, "What now, Ma'am?"

Twilight watched with bated breath, swallowing on a dry mouth at the question. "Oh, Applejack, you're really beautiful. I've never felt like this for anypony like I do for you. I've never done this, with anypony."

Applejack gazed up at her and whispered, "Thank you, Twilight," in a voice laden with emotion.

"Applejack?" She took a deep breath. She fought to get the words out steady, stripping them of all the pleases and gentle politeness that she instinctively used. To make Applejack happy, she had to be firm. Commanding. "Applejack. Show me your breasts now."

Applejack's eyes widened, a shudder running through her. "Yes, Ma'am," she breathed, and reached behind herself to unhook her bra. Moving slowly but steadily, she eased it loose, then slid one strap after the other down her toned arms. Finally, her hands cupping the loose bra against her chest, she lowered her hands to reveal large, rounded breasts capped with achingly hard nipples of darker orange. A red flush rode her cheeks, her lips parted, wearing only boots, shorts and her ever-present hat. Swallowing, she added huskily, "Ah hope you like me, Ma'am."

Twilight's hand curled closed, her nails pressing against her palm, and she shivered. "Oh, oh Applejack... I never realised how much I wanted to see you like this. Stand up, please."

"Yes Ma'am." The orange mare slowly got to her feet, deliberately imparting a sway to her breasts as she came to a stop, her shoulders back to push out her chest in desperate desire for Twilight's approval.

Moving slowly, almost as though she were afraid she might scare the moment away, Twilight stepped forward. Her hands rose, and quietly settled over Applejack's outthrust breasts. "You're so warm..." Twilight murmured, and softly squeezed.

"Uhh!" Applejack gasped aloud. Biting her lower lip hard enough to leave tooth marks, she breathed, "Please Ma'am, touch mah boobs."

Twilight nodded, her expression rapt with fascination, and spoke softly. "Applejack. Put your hands on your ass and squeeze, please. Don't move them until I say."

"Anything you want, Ma'am. I want to obey. Anything you say." Her hands moved back to her muscular ass and squeezed firmly through her shorts, prompting another groan from her lips.

"That's a good pony, Applejack. You're my pony now." Twilight squeezed and kneaded Applejack's generous breasts with fascination, releasing one to concentrate on pinching her taut nipple the way Twilight liked to do to her own.

"Yes! Yes, Ma'am, Ah'm your pony, I belong to you!" Applejack gasped.

Twilight was lost in a haze of lust. No matter what she had intended, no matter that this was all the result of a terrible mistake, she couldn't help herself. She wanted this more than anything she'd ever wanted. Before she'd even consciously thought about it, she'd bent down and drawn Applejack's nipple into her mouth, sucking and flicking her tongue back and forth over it.

"Aaaah! Oh mah stars, yes, please Ma'am, yes," Applejack yelped, her hands tightening on her own ass and arching her back to push her chest against Twilight's lips.

Breaking away, Twilight suddenly pushed her slimmer body against Applejack, leaning up to kiss her with desperate need. Her horn collided with Applejack's hat and pushed it askew, Twilight seizing the brim and tossing it aside without hesitation. The other pony's mouth was so soft and warm, and as Applejack's tongue met hers she pressed herself harder against her.

The kiss finally broke, leaving Applejack dizzy. Chest heaving with her breaths, she begged, "Please Ma'am, would you take your top off this time? Ah want to see you."

Twilight's head swam, taking a moment to process the request before she felt a flash of shyness, quickly overruled by her maddening lust. Nonetheless, her cheeks flushed hotly as she wordlessly reached down for the bottom of her purple jumper and peeled it off over her head, taking the light undershirt with it. Her bra beneath was simple and white, and she hesitated, looking to Applejack for reassurance.

"You're so darn pretty, Ma'am. Please," the blonde mare whispered.

Twilight took a deep breath, and reached back to undo her bra, tugging it off all at once while her nerve held. Her breasts were smaller than Applejack's, high and firm, with dark purple nipples standing out stiffly. A touch shyly, she asked softly, "Do you like them?"

"Yes Ma'am, oh yes..." Leaning closer, nearly enough for their skin to touch, she entreated, "Make me serve you, Ma'am, make me please you, Ah want to be forced. Stars, I've never felt this good, this hot!"

Twilight's breath caught, a visible shudder running through her. "Yes, yes... Applejack! You're completely under my spell, you have to do as you're told. Pleasure my breasts now."

"Yes Ma'am, I'm completely under your spell." Pressing closer, Applejack rubbed her breasts against Twilight's, breathing heavily, before she pulled back enough to take Twilight's breasts in her hands. Sweeping her thumbs back and forth over the deep purple nipples, she breathed, "I love your boobs, Ma'am. Ah'm so hot, I can barely stand it."

Twilight's knees weakened, and her hand moved between her legs to rub insistently against herself, gasping and groaning. Her inarticulate sounds of pleasure only grew louder as Applejack's warm tongue curled around one nipple, her knees weakening to the point of collapse. It was too much. It was too much. "Ahh, Applejack - wait, stop," she finally panted.

Applejack immediately drew back with a look of frustrated longing, breathing, "Yes, Ma'am."

Twilight seized the fastenings to her loose pants and fumbled them open, shoving them down her legs and kicking them away. Her white panties clung to her, soaked, and she peeled them off to expose her lightly furred sex, purple and pink to match her mane and tail. Nodding at Applejack, panting with need, she managed, "You too."

"Yes Ma'am!" Eagerly, her eyes on Twilight's naked body, she undid the fastenings of her shorts and caught her panties with her thumbs, sliding both down her toned legs together and working them off over her boots, her only remaining clothing. Her sex was bare, trimmed smooth with just a hint of blonde fur showing. She began to hurriedly undo her boots, but Twilight stopped her with an upraised hand.

"Leave those. You look very cute wearing nothing but your boots, Applejack."

Applejack blushed hard, the compliment seeming to get to her more than her nudity. "Thank you Ma'am! You're beautiful Ma'am. You're so- mmf!"

Twilight surged against her and kissed the other pony deeply in a moment of desperate impulsiveness, not daring to let her inner fire waver for a moment for fear her nervousness might creep back. Her hands slid up and down Applejack's flanks, caressing the cutie marks there, then worked back to caress Applejack's ass and explore the base of her tail. Little gasps and groans escaped her lips as she rubbed her body against her. "You're all mine, Applejack."

"Yes, Ah'm all yours, all yours," Applejack breathed in ecstasy against Twilight's lips.

Twilight's horn began to glow, and upstairs her small bed shuddered as pink mist surrounded it. With a sudden rush, it teleported down to thump solidly onto the floor behind Twilight, and before Applejack knew what was happening, she'd pulled Applejack backwards to lie naked against her among her neatly folded blankets.

Cupping one of the other pony's soft breasts and firmly rubbing her knuckles up and down her own sex, she whimpered, "Applejack, I need you to help me, it's too much, I need you right now."

Panting heavily, Applejack mustered a grin and breathed, "Make me do what you want, Ma'am."

"Applejack, I order you to get between my legs and do something about my sex right now!"

"Yes Ma'am!" she replied with cheerful enthusiasm. Sliding down the bed and pushing her thick blonde hair back over her shoulders, she gazed at Twilight's exposed pussy with fascination. Not entirely certain of herself, but desperate to please, she thrust out her tongue and began licking.

Twilight jerked, her back arching, and she seized her breasts and kneaded them roughly. The sensation of Applejack's tongue was completely new, and she shuddered and moaned her pleasure louder and louder in broken gasps. Looking down her own body at Applejack, she pushed out the words, "Touch yourself, Applejack. Don't - ohh! Don't stop."

"Yes! Yes Ma'am, I won't, I swear, I-" Applejack groaned, then gave up speaking and went back to her vigorous licking. Her hand snaked down and began rubbing her smooth slit firmly, slick and hot beneath her fingers.

Twilight was lost in a haze of pleasure, no longer aware of anything but Applejack and her own body, moaning and writhing beneath the other pony's inexpert tongue. Words spilled from her lips that she barely heard, urging Applejack on, breaking into fragments as she tensed. Her orgasm rushed over her, as sharp and sudden as an electric shock, and her hands clawed at the folded blankets beneath her. Finally, she came down enough to pant weakly, "Stop, Applejack, enough."

Lifting her head and wiping her lips with her fingers, Applejack stroked the dampness across her own breasts, her fingers busily working between her legs. In a strained voice, she asked, "C'n I please keep - touching myself - Ma'am-" and at Twilight's instinctive, "Of course!" she groaned in thanks and rolled onto her side. Her orgasm came quickly now that she could concentrate on her own pleasure and she panted loud, ragged breaths as her pussy tensed around her fingers again and again.

Twilight watched her, and reached out to stroke her freckled cheek as she calmed. "Oh, Applejack. I've never felt anything like that before. Come up here and hold me, please."

Applejack smiled and wriggled up Twilight's body to lie against her, holding the slimmer mare in her arms and nuzzling close. "Anything you say," she murmured, her eyes mostly closed.

Twilight settled against the orange pony's body, her fingers tenderly exploring the three apple mark on her thigh, tugging one of the disturbed blankets over them. Deep down, she knew that, soon, she'd have to make Applejack her normal self, that she'd have to hide these memories from her and give her some thin justification for where the time had gone. That, very soon, Applejack would think of her as nothing more than her good friend. It would hurt, but she couldn't just replace Applejack with this - adoring, submissive lover. It wasn't her.

Soon, she'd have to undo all that she had done. But not yet. For a few more minutes, not yet.

Author's Notes:

Falling in love with someone that technically doesn't exist is going to break your heart, Twilight.
