Rarity was in her bedroom trying to design a new dress for herself, nor for any event in particular, just because she wanted to. She was, unfortunately, struggling to concentrate as Apple Bloom and Scootaloo were visiting Sweetie Belle and making quite a lot of noise along the hall from her room and was about to go and ask them to keep it down when her phone rang. It was Applejack.

“Hey, it’s me,” came Applejack's voice. “Big Mac and Granny are making a delivery and won’t be back ‘till late and I’m guessing you know where Apple Bloom is.”

“I do indeed,” replied Rarity as a shriek came from Sweetie Belle’s room.

“Point being, I’m alone on the farm all afternoon. Fancy keeping me company?”

Rarity’s heart started beating furiously with excitement, it had been a week since their last time together and she’d been planning. It was difficult getting time alone somewhere comfortable with the required shower due to both living with their families, Applejack’s work on the farm and Rarity’s job in the boutique. It was a rare occurrence for her to be the last employee there and her boss was prone to coming in at night to work on new designs so they couldn’t rely on that. “I think that would be a marvellous idea,” she said, trying not to let her excitement be heard, “I’ll come right over.”

“Can’t wait,” said Applejack as they both hung up.

It was finally time to put her plans into action. She went over to her closet and pulled out a box hidden at the back. She’d bought a few things from an online sex shop including a vibrator that she was desperate to try but she wanted her first deep penetration to be from Applejack.

As she was packing the outfit she assembled for herself a very naughty thought came into her head. Instead of packing her outfit, she put it on with a pair of sensible shoes and a long but stylish coat so as not to attract attention. She made sure her makeup and hair were perfect, packed the things from her box and a very high pair of heels into one of her many handbags before heading out. She’d need to take the bus over to Sweet Apple Acres which, considering what she was wearing, was a bit of risk. As it turned out she was rather exited by the risky journey.

As they approached her stop she made sure her coat was still fully covering her before disembarking and walking up the road to the house. She changed into her heels at the front door, checked her hair in the mirror she always kept in her handbag, and knocked.

Applejack was sitting in her kitchen waiting for Rarity when she heard the knock. She jumped up and dashed to the door, slowing down and composing herself before she opened. Rarity was standing there, several inches taller than normal and looking radiant.

“Are we alone?” she asked as she walked in.

“Just the two of us,” confirmed Applejack, closing and locking the door.

Rarity put her handbag down and, without a word, dropped her coat to the ground. This revealed a red corset with thin black strips highlighting the bones that pushed her breasts up and together giving her cleavage you could get lost in. To set Applejack going even more, she was wearing black stockings suspended from the corset, massive black heels and elbow length black velvet gloves with no panties. Applejack could only stand there and stare. Rarity grinned, that was the effect she’d hoped for.

“You came all the way here on the bus like that?” asked an incredulous Applejack.

“I did,” answered Rarity slightly proud of herself, “Do you like it?”

“Like would be an understatement.” Applejack could feel her desire rising and it wouldn’t be long before she would have to have her.

“I brought a little something for you to wear too.”

She turned round and bent down to reach her bag, keeping her legs straight so her ass would be on proud display, showing Applejack everything. Applejack couldn’t help herself, she stepped close and smacked Rarity gently on the ass.

“Mmm, control yourself darling we’ve not even started.” She felt a rush of pleasure go though her at the smack and she could feel something trickling down her thigh. Not yet, she thought to herself, I need to stay in control a little longer.

She stood up and handed Applejack a bundle of latex. “I don’t know if you’ll be too keen on it but I’d love to see you in it.”

Applejack was a little suspicious but now was not the time to refuse. “Come on up to the bedroom,” she said as she made her way up the stairs.

“Could you change in the bathroom?” asked Rarity, “I want to see the grand reveal.”

“I guess so.”

Rarity went into Applejack’s room and to her surprise found it was clean. She lay down on the bed, trying to find a comfy position that was also capable of saying ‘come hither’.

After a few minutes, Applejack open the door and stepped inside wearing a latex cat suit with built in four inch heels and a zip running from the collar all the way down between her legs and then up a little at the back as well. Applejack wasn’t sure of it but as Rarity had to take a few deep breaths before saying anything she clearly liked it.

“You look amazing Darling,” she finally managed to get out, her voice a little shaky. She could feel her mind getting foggy already as lust took over.

Applejack could see it too. The deep shaky breaths meant Rarity was losing herself again. She thought she’d try something. “Come here,” she ordered.

Rarity immediately got off the bed without a word and stood before her, chest heaving in that wonderful corset.

“Kneel.”

Rarity did so.

“Unzip me.”

Rarity reached between Applejack’s legs for the zip and brought it down, under and back up, revealing an already wet pussy a few inches from Rarity’s face.

“Lick.”

Rarity leant in and began licking up and down Applejack’s wet slit, her mind now just a fog of lust yearning to be used. Applejack placed her hand on the back of Rarity’s head and pressed her into her pussy, Rarity continued licking as best she could but the force meant she couldn’t have free movement.

“Fuck me.”

Rarity, unable to get any fingers in due to Applejack holding her head, immediately plunged her tongue into Applejack’s pussy and began fucking her earnestly. Applejack just stood still and enjoyed her slut’s tongue. When she felt her knees getting weak she stepped back leaving Rarity with her tongue hanging out, staring up at her, her eyes begging for more. It was then Applejack noticed something on the bed.

She strode over and picked it up. It was a vibrator, six inches long and one in diameter. It wasn’t hers so Rarity must have brought it.

“Bend over the bed,” she ordered not even looking at Rarity.

Rarity immediately came over and bent over the bed, her ass right in front of Applejack who immediately spanked her. Rarity gasped at the first hit and then began to moan as she was struck repeatedly. With no warning, Applejack thrust the vibrator deep into Rarity’s pussy.

Rarity yelped at the intruder deep inside her before hanging her head and groaning at the pressure within her. Applejack just grinned and pushed the button on the base. Rarity let out a small moan as Applejack slowly withdrew the vibe and let out another yelp as she slammed it back in. After a few cycles of this Rarity was already on the verge of orgasm, her tongue hanging out as she grasped the bed covers.

“You don’t get to cum before I do slut,” commanded Applejack as she pulled the vibe out. She licked the tip of the vibrator to taste Rarity’s desire before lying down on the bed next to Rarity and placed the vibe in front of her mouth. “Suck it clean.”

Rarity immediately took as much as she could in her mouth and enthusiastically sucked it clean.

“All the way.”

Rarity forced herself to take the entire length, gagging as Applejack pushed it into her throat.

“Good slut,” said Applejack as she withdrew it, “Now take this and make me cum, use your tongue as well.”

Rarity got on her knees between Applejacks legs and slowly inserted the vibrator while using her tongue on Applejacks clit.

“Good slut, a little faster.”

Rarity obeyed.

“Mmmm, good slut.” Applejack just lay back and enjoyed the attention. As Rarity kept working away it wasn’t long before she felt her orgasm mounting. She pulled the zip up from where Rarity had left it on her stomach to her neck so she could get access to her tits and started kneading her chest with her strong hands as her hips involuntarily bucked as Rarity tipped her over the edge of orgasm.

“Mmmm, Ah yes! Good slut!” she yelled as her orgasm took her.

Rarity fucked her with the vibe as fast as she could which brought out even greater moans from Applejack. As she came down from her orgasm, Applejack propped herself up on her elbows to look down at Rarity. She was again covered in cum and still carrying out her last order.

“You can stop now.”

Rarity pulled back and removed the vibe from Applejack’s pussy.

“I’ve got a surprise for you, slut.”

Rarity watched blankly as Applejack walked over to her closet and took something out of a box hidden at the back. She seemed to be fiddling with something in front of herself before pulling some straps from between her legs and fastening them.

When she turned round Rarity’s mouth dropped open at the sight in front of her. Dangling between Applejack’s legs was a massive dildo. It was at least twelve inches long and probably three in diameter. Applejack was a firm believer that if you were going to do something you should do it right and, having studied online porn, believed that bigger was better.

“Do you like it slut?”

I can’t take that, it’ll break me, thought Rarity, I need to tell her I can’t do this. Unfortunately, the part of her mind in control of her body was afflicted with the fog of lust and had other ideas. “Yes,” she breathed in awe.

“I knew you would,” said Applejack, stroking her strap-on, “I thought, given our pony aspects, a nice horse sized cock would be good for you. Get on the bed, lie on your back.”

Rarity did so, her legs over the end of the bed. Applejack grabbed her slut’s ankles and lifted them up, placing them against her shoulders. She paused for a moment admiring the view of her slut in her corseted finery and her face covered in cum. She then grabbed her strap-on and positioned it in front of Rarity’s dripping pussy. “Ready?” Rarity didn’t speak but the look of desperation in her eyes said everything.

Applejack slowly pushed her massive head into Rarity’s pussy. There was a lot of resistance as she was very tight which brought a lot of pained grunting from Rarity. When the head finally slipped in, there was a loud, pained gasp from Rarity. Applejack gave her a few seconds to recover before she pushed in further to more grunts from Rarity.

As she continued pushing her strap-on into her slut, Rarity’s pussy was loosening as she acclimatised to the new situation, letting Applejack push in deeper and quicker. When the entire length was firmly in Rarity’s pussy, Applejack paused again to let her acclimatise before pulling out all but the head and ramming it back in.

This caused Rarity to throw her head back and yelp as the shock of the thrust moved through her entire body. Applejack starting thrusting hard and fast, causing yelps of pain and pleasure with each thrust.

“You like my horse cock, slut?”

“Yes!” screamed Rarity as she approached her climax already.

Her juices coating the strap-on just made it slide in and out even easier so Applejack starting ramming her horse cock even harder into Rarity’s pussy. Rarity was now screaming constantly as her orgasm mounted. While her body was screaming in pleasure, her mind, hidden away behind the fog, was screaming for Applejack to stop, this hurt.

Applejack reached down and grabbed the top of Rarity’s corset, pulled it down, snapping some of the bones, to expose her porcelain white tits. She leaned forward, letting Rarity’s legs hold her weight as she reached down with both hands and roughly grabbed the pair of beautiful mounds, squeezing hard enough to leave prints.

Rarity was now completely gone and seemed unable to acknowledge anything but pleasure because the little corner of her mind that could still think was firmly imprisoned behind the fog. Her arms were lying limp by her side, her eyes rolled back in her head and her tongue hanging out. The screams had stopped and there was now only gasps accompanying each thrust.

As Rarity’s orgasm ended, leaving her lying on the bed on the verge of unconsciousness, Applejack pulled the strap-on out of her pussy to a sucking sound. She ran her hands over the dripping cock and licked them clean.

She pushed the strap-on back into her slut which drew only a slight moan from Rarity and unbuckled it and re-buckled it around Rarity to keep the massive cock in her slut. This revealed it was a double sided strap-on with a shorter, six inch dildo that was equally as wet from her own juices. As she looked down at her slut she realised Rarity was in no state to be able to use the strap-on to fuck her.

“I didn’t cum, slut. So you’ll finish me off.”

She got on the bed and sat straddling the barley conscious Rarity’s face. Rarity rallied as much energy as she could and began to lick. She blearily began tongue fucking Applejack as Applejack reached down and started playing with her own clit.

After a minute or so, Applejack was on the verge of cumming, moaning and grinding against Rarity’s face as she worked her clit faster and demanded Rarity fuck her faster too. As she went over the edge, Applejack pushed herself down on Rarity as her cum covered her slut’s face.

“Ah, good slut,” she said as she dismounted Rarity.

Applejack stood back and admired her cum covered slut. Her hair was dishevelled, her makeup was smeared everywhere, her chest was heaving as she panted and there was quite a bit of moisture soaking into Applejacks bed covers beneath her pussy. This was what she loved, seeing Rarity in this state was almost as good as cumming.

She zipped up her catsuit before pulling Rarity up into a sitting position. This caused the massive pressure of the horse cock inside her to move and her entire body quivered at the sensation.

“You’re going to keep that in while you clean yourself up,” ordered Applejack grabbing the dildo that had previously been inside her and pushing it to put pressure on the horse cock.

Applejack went over to the mirror in her room and admired herself in her latex finery. She really did look good in this, it perfectly accented her curves and the heels made her legs look longer and sexy. This was definitely a keeper. She noticed Rarity behind her was still sitting on the bed.

“Are you alright sugercube?” she asked.

“Yes, I’m fine,” said Rarity softly as the fog faded enough for her thoughts to creep out, “I just need to get a little steadier on my feet before I dare try and shower.”

“You take your time, but that cock stays in you, slut.”

“Yes,” replied Rarity, a little distantly.

As Rarity grew confident that her legs could support her she headed for the shower, walking rather awkwardly due to the pressure inside her. Now the fog was clearing from her mind she was feeling the pain it had caused, it felt like her pussy was on fire.

In the shower she broke down in tears. One of her closest friends had just used her as a living sex toy and, worse, she had loved it. She had become a cheap slut who liked being used, she had wanted this massive cock that was still inside her that hurt her so much. This wasn’t her, she wasn’t a mindless slut but here she was, with a horse cock inside her and washing cum from her face. Now she could think again, she didn’t like what they had just done but Applejack’s last order was still in her head and she couldn’t bring herself to remove the cock from inside her.

When she recovered her composure she washed and dried herself before going back to Applejack’s room with her lingerie in a small, cum soaked bundle. She needed to tell Applejack this wasn’t what she had wanted from their friends with benefits arrangement. Unfortunately, when she got back to the room, Applejack was lying on her bed, still wearing the catsuit and working Rarity’s vibrator in her pussy.

“Slut, bring that strap-on over here and fuck me.”

Rarity paused for a second as the desire to tell Applejack her feelings on what happened and the new order battled in her head. Without saying a word, Rarity went over to Applejack, straddling her on the bed, and started fucking her with the six inch strap-on. This caused the horse cock insider her to move around getting her horny again. The pressure was amazing, said the fog, you love this. Rarity kept fucking Applejack as both began moaning. It was amazing, she loved it.

As Rarity increased the speed of her thrusts at Applejack’s order she felt her orgasm hit her. Her arms gave way underneath her and she flopped down onto Applejack, who began bucking her hips onto the strap-on as Rarity was no longer capable of thrusting. Applejack smacked her hard on the ass, causing more moaning from her slut. She kept smacking Rarity as she continued bucking against the strap-on. When her own orgasm hit her she grasped Rarity’s ass and pushed her down as she pushed her hips up, trying to get more of the cock inside her.

As their orgasms receded, Applejack rolled Rarity off her. “That was good,” she proclaimed, “I think we’re done here, I’m satisfied anyhow. You can go home and I can get on with my chorse.”

Rarity got off the bed, feeling ashamed because she hadn’t even resisted the order for sex. “Can I borrow some clothes to wear home?” asked Rarity meekly.

Applejack looked at her slut, sitting there with a six inch cock between her legs. “On one condition.” She walked over to Rarity and grabbed the cock, twisting it and pushing it so it came off the harness. “I’ll give you clothes if you keep that big un’ in you till you get home.”

Rarity’s mind told her to argue, but the fog that was still present stopped her and made her nod her head.

Applejack looked out some clothes for her as Rarity gathered her things, putting her cum soaked lingerie in her bag with her dildo, after she had sucked Applejack's juices from it at her order.

As she left Sweet Apple Acres, she was wracked with shame, only just keeping herself from breaking down in tears as her thoughts from the shower returned.

Author's Note

I wasn't entirely sure Rarity would be the kind to go anywhere by bus but I wanted that risk of exhibitionism in the story.
