More Than Friendship

Rarity had kept the horse cock in until she was home, as ordered, where Sweetie Belle had immediately grabbed her before she could go to her room and remove it. She’d then spent half an hour helping her little sister with her homework, the massive cock nearly making her moan aloud when she changed sitting position. The worst part was that she was turned on by it.

Enough of the fog had stayed with her all evening preventing her from removing the massive cock inside her. It was all she could do to hold the fog back and stop herself from cumming every time it moved for the entire evening. Worse, was that she had been unable to bring herself to remove it when she was going to bed and ended up sleeping with it still inside her

When she woke up the next morning the fog was gone and she was horrified with herself, the cum slut had kept some control all night. She unbuckled the harness and wrenched the cock out of herself and threw it across the room in disgust and fear of the control the damned fog had over her. The void within her was equally horrifying, her pussy was gaping and she could feel the cool air deep inside her. She broke down in tears at what had she had become.

The next few days had been very painful, not just her pussy but also the red hand prints on her ass. She hoped none of her friends noticed her walking carefully, Applejack certainly did but the others must have assumed she was walking funny because she hurt something during a run.

She didn’t have the courage to bring up her disgust at what they had done to Applejack due to her shame. Unfortunately, Applejack brought it up with her. It was Wednesday, and Rarity had been watching Rainbow Dash and the hockey team training in their lunch break when Applejack appeared next to her.

“I see you’re still walkin’ funny after the horse cock,” she said as if this was normal conversation.

Rarity froze at those words.

“How’s your ass?” asked Applejack as she smacked it.

The worst thing happened for Rarity, a rush of pleasure ran through her.

“I’m going to be alone on the farm on Sunday morning so if you bring my strap-on over we’ll have some more fun. I’ve got another little something being delivered just for you.”

Rarity wanted to say she would be busy but nothing came out of her mouth.

“You’re coming over, right?” insisted Applejack, smacking Rarity on the ass quite hard to focus her mind.

“Yes,” said Rarity softly.

Applejack reached down behind Rarity and between her legs, under her skirt but above her panties, and ran a finger up Rarity’s slit and back to pause over her asshole.

“You’re going to love it slut,” said Applejack as she walked away.

Rarity spent the rest of the week trying to tell Applejack she didn’t want to do this but every time she brought it up the fog reared its slutty head and stopped her from saying what she wanted.

When Sunday came round, Rarity was filled with dread. All she had to do was not go to Sweet Apple Acres but she didn’t trust herself not to go, not if the fog came in. As it turned out, her worst enemy was muscle memory. Her phone rang and she immediately picked it up and answered before she had registered the name of the caller.

“Come on over slut, the family’s all out,” said Applejack.

Immediately the fog came in and told her to go. “I don’t know if I’m up for it today,” lied Rarity, trying to get out of it before the fog took her thoughts away from her.

“Oh come on slut, you promised you’d come over here and we’d have some fun.”

“I did promise,” said Rarity’s voice but the thought hadn’t been hers.

“Yes you did, and you’ve still got my strap-on so you need to bring that back.”

“Yes, I do,” said a quiet voice.

“Well get that and your little thing and get yourself over here. And bring some sexy underwear for yourself, though you don’t need to wear it coming here.”

Rarity went over to her drawers and looked out something nice. “Would you like me in a corset again?” she asked.

“You did look mighty fine in the last one, so yeah. Get yourself a nice corset and stockings again, that’s your new slut uniform. And your heels.”

In a slight dreamlike state Rarity packed her new uniform, the giant strap-on and her own vibrator into a large handbag and left for Applejack’s. On the bus over she was unable to keep her hand out of her bag and stroking the horse cock that she longed to be fucked with again.

Applejack met her at the door and took her up to her bedroom before ordering Rarity to put on her uniform. She did as ordered and changed in front of Applejack.

“Lie on the bed, ass up,” came her second order.

Rarity did so.

“Hands between your legs slut.”

Rarity moved her hands back and between her legs where Applejack grabbed them and tied them tight with rope before fixing them in position by tying them to her knees. This left Rarity supporting her herself on her knees and head.

“Good slut,” said Applejack. “Today we’re going to be testing your limits and introducing some anal fun.”

The little part of her mind that was still Rarity recoiled in horror at this thought but she was unable to say or do anything to express it. She heard Applejack squirt something from a bottle and prayed it was lube. She couldn’t stop what was going to happen, only hope it wouldn’t hurt too much.

Applejack smacked Rarity on the ass and then pushed a butt plug into her. This made Rarity yelp and then, to the horror of her imprisoned thoughts, moan.

“Right, we’re starting small. I don’t want to break my favourite fuck toy, do I?” said Applejack. “Well done for bringing your little thing. Why don’t we stretch your pussy while we’re at it.”

Applejack pushed the vibrator into Rarity’s pussy and turned it on. “Say thank you slut.”

“Thank you,” came Rarity’s voice.

“I think you should call me ‘Mistress’ now a well.”

“Thank you Mistress.”

“Good slut,” said Applejack as she smacked Rarity’s ass extremely hard, “Hmm, that dildo ain’t gonna stay in you by itself. I know.”

Applejack got another length of rope and ran it up between Rarity’s ass cheeks and then over one of her shoulders. She pulled it tight causing some rope burn to Rarity’s shoulder as she tied it.

“There, that’ll keep it in,” said Applejack, satisfied with her solution, “Now I’ve got some chores to do so you stay here and stretch yourself while I’m busy. I’ve got something to entertain you while you’re alone too.”

Applejack got her laptop out and set in front of Rarity’s face and set a playlist of videos going. “These’ll teach you how you should behave.”

At that, she left. Rarity was alone, lying on her friend’s bed, trussed up and filled full. To her horror, the pleasure from the vibe in her pussy and plug in her ass was immense and in just two minutes she came for the first time. The videos she had no choice but to watch were of good slaves obeying their mistresses and being used over and over, just as she would be, because she is a good slut who obeys her mistress.

By the time Applejack returned about twenty minutes later, though Rarity had no frame of reference, she had came five times. Her legs were damp with cum and it also run down her stomach and under her corset.

“Wow, you’ve been enjoying yourself slut,” said Applejack as she approached Rarity and smacked her on the ass with a riding crop she’d brought in from the stables. This made her slut cum again.

“I thought a crop seemed appropriate for the horse cock theme of your life,” said Applejack as she let her slut see what she took such pleasure from, “Step two.”

The little corner of her mind that was Rarity felt great relief as the rope was untied and the vibrator and butt plug were removed but that didn’t last long as she heard the bottle of lube being squeezed again.

“That was a little one, just half an inch at the base, I’m bumping you up to one and half now.”

Rarity’s mind and her voice were in agreement as it was slowly pushed into her ass, both were screaming in pain, the difference was that her voice was also begging her Mistress for it.

“Calm down slut, you’ll learn to love it.”

As the plug popped inside her and Rarity felt as if she had just been torn open.

“And it’s time for an old friend,” came Applejack's voice from behind her, “We’ll go for the eight inch one, didn’t get a chance to use it on you the other day and we gotta get you loosened up for the big ‘un since your ass’ll be full too.”

Rarity felt the pressure from the smaller of the massive strap-ons, probably two inches in diameter, pushing into her pussy, stretching her as much as the plug in her ass. Her mind knew she didn’t want this but the only thought it could express was that the pressure from the two toys felt amazing. She loved her Mistress. She would obey any command like a good slave should.

As the base of the strap-on reached her pussy, Applejack fastened the harness around her. She moved round the bed to look at her slut before pulling down the top of the corset to let Rarity’s tits hang free.

“That’s a proper slut, everything on show for your Mistress. Do you like what I’m doing for you?”

“Yes,” answered Rarity, nearing orgasm just from the pressure. She felt a hugely painful sting against the side of her tit that made her wince.

“Yes what?”

“Yes Mistress.”

“Better,” said Applejack hitting her again. “Don’t forget your manners again, I know how important they are to ya. While you stretch out some more, I’ve got another few things to take care of.”

Applejack again left Rarity alone, but not before turning on the vibrator in the new butt plug making her slut groan in pleasure. Rarity was left, completely consumed by the fog of lust for half an hour, unable to move and unable to stop cumming.

When Applejack returned, Rarity was incapable of communication, she was just a mindless cum slave only concerned with obeying orders.

“That’s all my chores done, time to have some fun with my slave. Since you’ve cum so much you must be in need of a drink.”

Applejack untied her slave, leaving her holes filled and dragged her off the bed. Rarity fell in a heap on the floor.

“There’s a water bowl over there for you, have a drink.” There was no reason for this, she just wanted to see if her slave would do it.

Rarity crawled over to the bowl of water and began to drink by sucking it up. She felt a sting from the crop on her ass and immediately stopped.

“Lap it like a dog, slave.”

Rarity did so unquestioningly. It was a very inefficient way to drink and resulted in more water on the floor than in her mouth.

“That’s enough, slave,” said Applejack, “Back on the bed, all fours.”

Rarity immediately obeys, crawling back over to the bed and climbing up to present herself for use. Applejack unbuckled the strap-on and took the little one off the harness and attached the big horse cock. She lubed it up and positioned it at the entrance to Rarity’s pussy. “Do you want this, slave?”

“Yes Mistress,” came the toneless voice from her slave.

“Why are you here?” She asked.

“To be used by my mistress,” came the flat answer she had learned from the videos.

“Good slave, you deserve this,” said Applejack as she swiftly pushed the entire length of the massive horse cock into Rarity’s gaping cunt.

Rarity screamed in pain as Applejack started fucking her hard and fast, the horse cock felt as if it was going to destroy her organs as it pounded away inside her.

After a minute of this, the combined pain of the horse cock and butt plug was too great for any pleasure to co-exist for Rarity, Applejack slowed down and removed the plug. Even the fog that made up almost the entirety of Rarity’s mind now was relieved for a moment until the smaller of the strap-on attachments was pushed deep inside her ass.

As Applejack pulled both of the cocks out so just the head remained, Rarity groaned in agony, unable to go against her Mistress’ orders. Applejack then slammed both cocks inside her in unison caused screams of pain. There was no pleasure for Rarity anymore, even the fog couldn’t find any in this.

“Fine, if you can’t take it slut, we’ll try somethin’ smaller,” said an annoyed Applejack.

She pulled the cock out of her slave’s ass and pushed in the larger butt plug back in and turned the vibration on. “Though since you failed me, I’ll need to punish you.”

Applejack reached down for the rope that she’d used to keep the small vibrator in her slave’s pussy and tied it into a large loop. She leaned over Rarity’s back, burying the strap-on deep inside her, and put the rope in Rarity’s mouth.

As Applejack straightened up again she pulled back on the makeshift reins forcing Rarity’s head up. As she withdrew the cock from Rarity’s pussy she slackened the reins only to pull back sharply as she rammed her slave full again.

As Applejack rode her, there was some pleasure now for the fog that made up Rarity. The vibrations in her ass and her Mistress fucking her pussy brought her to the edge of orgasm, her pained moans making way for pleasured ones. She felt a familiar sharp sting on her tit which pushed her over the edge.

As her slave came, pressing forward against her reigns as shrieks and moans of ecstasy came forth uncontrollably as pleasure wracked her body, Applejack took in the beautiful sight. Her prissy friend, reduced to an obedient cum slut. This was what she loved most about her.

As her slave began coming down from the highs of orgasm, Applejack withdrew the strap-on and pushed Rarity over so she was lying on her back, throwing the reigns away. Taking a moment, Applejack surveyed her slave. Her eyes weren’t focused, her hair was a mess and her legs and stomach were soaked in her own cum and there were some red rectangles on her tits where she had enjoyed the sting of the crop. There were also a large gaping hole above the butt plug.

“I hadn’t planned on this but looking at your gaping cunt, I can’t resist,” said Applejack as she grabbed the lube and rubbed it over her hand.

She pushed the tips of her fingers into Rarity’s cunt, which was so wet the lube wasn’t really required but Applejack didn’t want to risk seriously hurting her, this could be risky. Her fingers easily slipped in right to the knuckles and only took a little more pressure before her whole hand slipped inside Rarity.

Rarity was almost passing out from the pleasure that this brought. Her Mistress’ fingers individually exploring her insides creating five little spots of electricity deep within her. As Applejack kept pushing her arm slowly into her slave’s cunt, she realised she could feel the vibrations from the plug still in Rarity’s ass. No wonder her slave was writhing in pleasure.

Applejack felt Rarity’s pussy clench around her forearm as she came. She kept up her motions inside her slave until she realised there was no sound coming from Rarity, it was just her muscles clenching from automatically. She gently pulled out and stood up to check if Rarity was alright. Panic immediately set in when she noticed Rarity was motionless with her mouth hanging open and her eyes staring vacantly into nothingness.

Applejack jumped onto the bed and shook Rarity’s shoulders gently. She had never experienced relief like it when, after a few terrifying seconds, Rarity blinked and look up at her.

“Thank you Mistress,” came a voice so weak it was barely audible.

“You rest for a bit Rarity,” said Applejack knowing she had pushed this too far.

As Rarity closed her eyes as ordered, Applejack took off her stockings and heels and unfastened the corset in case it was restricting her breathing. She wrapped Rarity in her bed covers and stayed watching her for the next hour to make sure she kept breathing.

When Rarity rolled over in bed and groaned in pain, Applejack woke her up.

“Hey, are you alright if we get you cleaned up?”

“Yes Mistress,” came the feeble reply.

“No. No ‘Mistress’, that’s only for sex, I’m Applejack now.”

“Yes Mistress Applejack.”

She decided to just let it slide, Rarity needed time to get her thoughts together. Applejack carried her mindless friend through to the bathroom and laid her gently in the bath before filling the basin full of hot water and cleaning her. This was just like their time in the boutique.

With her washed and dried, Applejack took her back to the bedroom and helped her get dressed. Rarity was capable of walking unaided now and seemed to be coming back to herself.

“Come on Sugercube, I’ll take you home.”

“Thank you Applejack,” said Rarity, sounding more like herself.

When they arrived at Rarity’s, her parents and Sweetie Belle were understandably concerned about her and Applejack had to make something up. They had gone riding and she’d fell off. Nothing was broken but she needed to rest. The three of them fussed over Rarity as Applejack helped them get Rarity to bed.

As she headed back home, Applejack was wracked with guilt. That had gone far too far, no more extreme insertions like that. There were lots of other things they could do and she could still use the strap-on, just not in both holes at once. She needed to apologise first thing tomorrow at school, if Rarity was physically capable of going to school. She didn’t sleep well that night, her nightmares showing her killing her friend by ripping her in half.
