Today started like any other. Rarity had just made the deal with three queens of a great country for a 100 dresses each and the most handsome princess asked for her hoof in marriage, and her three perfect foals were telling her how much they loved her. Then she finally opened her eyes to her bedroom. It was boring compared to her dreams. She sat up rubbing the sleepies form of her eyes.

"One day." She told herself, "One day." She climbed out of bed and marched out. She headed to Sweetie Belle's room but remembered her sister was not staying with her this week. No, Sweetie Belle and her parents were visiting family far off. Just as well, Rarity didn't want her precious little sister around today. Today was the day she her side business opened this year. She was almost happy, after all her favorite customer was coming today.

She decided to clean up. Floors, windows, and everything that had a solid layer of dust on it. She put all her mannequins and other supply in her work room. She would not be using them for a while. She took the occupied models and put them on display. Just because she was making back room deals didn't mean front room ones had to be neglected. Even if they were rare. She changed her bed sheets with fresh linen; nothing was too good for her number customer. She took the removed sheet to the laundry room, or as her mother would call it 'The Family Shame Room.' There she took care of Opal's area. Finally, she cleaned up herself. A nice bath with extra strength conditioner to give her mane extra luster. She let the vitamins and nutrients soak in. After, she rised off and went to apply make-up. Not too much, just enough to be sexy.

Rarity finished just in time. Her favorite customer was here. She watched him from her bedroom window. He was one of the most handsome stallions in ponyville. He was nice and polite, spoke kindly and always minded his manner, and on top of all that his winning trait was that he wasn't selfish like so many others. He always made sure to take care her as much as she would him. She would take him any day, even if he was strange order. She troted downstairs to greet him. The doorbell rang as she approached the door. Using her magic to open the door she greeted her first customer, "Big Mac, please come in. How are you."

The red stallion entered, "Good day Miss Rarity."

"Mac, please." Rarity cooed, "Just Rarity will due."

"Yes ma'am."

"And pleasssse don't call me ma'am." Rarity sang, "We're practically the same age.

"Of course Rarity."

"Now wait here. I just remembered that I left the hat in the workroom." She opened the door to a room of cluster. Her goal in the back, because of course it is. Rarity sighed and started moving thing out of the way. "I still can't change my cutie mark."

"That's okay." Macintosh said in the showroom.

"I've learned how to change my voice." Rarity informed him.

"No need for that." He asked looking at the displays.

"I change my eye color. It's not too hard." Rarity was closing in on her target.

"That's okay," His eyes shifted to the floor, "I want to thank ya Rarity."

"Don't mention." She said from the workroom. "This is a business."

"Well I mean, thanks also for not telling anypony about... you know." Big Mac became redder.

"Oh Big Mac," Rarity called out, "You have nothing to be ashame of. Applejack is a beautiful mare in every way. She's strong and clever. Any stallion be lucky to have her."

"But she still my sister." Mac called back, "My little sister."

"Well she isn't little anymore darling," She said coming out with a cowboy hat, "And I'll tell you now. You won't hear a word from me if you decide to get with her."

He smiled just a bit, "Thanks."

"Sure thing," Rarity smiled backed, "Now go upstairs while I get ready."

He nod and trotted upstair. When he was out of sight she started her spell. She foused on her fur: not her skin. Did not want to repeat that mistake. Soon her aura came over her and changed the color of her coat from beautiful white to healthy orange. Next her mane, the aura washed over it changing it from lovely purple to a pretty yellow. Last, she put the hat on and done.

She trotted to her room. Opening the door she asked, "How do I look?"

Big Mac looked over to Rarity with his sister's color. "Oh! You look- You look- Umm..." Losted: he paused to gather his thoughts, "You look amazing." He said as she trotted to him.

"No need to rush." Rarity whisphered, "Foreplay is free."

Their lips make contact and their tongues caress one another. His hooves start to explore her body. Rubbing her neck and forelegs. Brush over her now golden mane. This was interupted with Rarity pulling back, "Let's go to the bed."

They trotted over and sat on the linen sheet and continued. This time Rarity joined in the exploration. Starting with his great muscles. The muscles that maintain Sweet Apple Acres. These and Applejack's muscles work the literal acres apples. From dawn to dust sweat drips off their massive frames. How must he feel to watch his beautiful sister's body work and see only forbidden fruit. Forced to settle with Rarity's lean body. While she made sure stay fit and healthy she could never have the firm tone AJ had naturaly. Luckly Big Mac could overlook this nick in his fantasy,

She continued her journey to its obvious destination. As she touched his spot a moan of tension sounded. Rarity was always impressed with how a pony's privates were hidden away. Out of public sight, but still easy to accept for restroom and other uses. She revealed the sizeble stud. It quickly came to its full size and she started working her tongue on it.

"Oh Aj" Macintosh moaned which cued Rarity to start the next stage of her service. She had become very skilled in this field. Never choking or even gaging as she worked a stud. Then, without surprise, Big Mac pulled on her to come over. After swinging her flank over he started at her own fancy bit. Always the gentlemen he made sure to please his lady friends. Most stallions just sit back and enjoy her oral services. Some just fulfill their part there and pay up. Leaving Rarity unsatisfied, not that it mattered. Is was business and that was job. Luckly this did the deal Big Mac. He alwayed return the favor, but something she did wonder if it was out of common code or a desire to love his sister. It didn't matter because neither answer would surprise her. What did surprise was Big Mac's premature climax, or rather just earlier that normal climax. He usually held out until the main act.

"I'm sorry." Big Mac apologized, "Applebloom been so active lately I haven't been able to relieve myself."

"It's fine." Rarity wiped her muzzle

"Hope you don't charge me extra." He smiled.

She tried to look crossed but she couldn't help smiling. They rearrange their bodies. Rarity laid face down on her pillow; her flank in the air. "Mount up cowboy."

Big Mac did with pleasure and grace. Smoothly inserting til fully in, and then pumping at an smooth, pleasureing pace. A real goldilocks. Not too fast, or too slow.

Oh Applejack, Rarity thought, you have no idea what you're missing out on.

The couple moved and sweated. Her fresh sheets were now damp. Her mane was getting stuck on her face and neck. Soon she was biting into her pillow to hold her near screams in. After many mighty thrusts Big Mac finished with a powerful load. Where his first shot was like firecracker, this was a full barrel of TNT. Heat swell inside Rarity and dipped out. The magnificent stallion collpased next to Rarity breathing heavily. Rarity checked her clock. Lunch had come, gone, and been forgotten. Rarity giggled. Stamina was definitely in Big Mac's list of strength.

"Well, I would invite you to lunch but Granny Smith is probability worrying." She climbed out and almost slipped on the 'AJ hat'. It must have fallen off at some point.

"I'll just tell her I took a snooze and over slept." Big Mac replied, "She'll believe it."

"Well, I'm going to get a late lunch from the cafe." She started to the door.

"I understand." Big Mac climbed out of bed, "I'll pay and leave."

Rarity turned around, "Oh Big Mac, I didn't mean it like that."

"It's fine." He put the money on the drawers. "Like you said. Granny Smith is probability worried about me."

Rarity sighed, "Yes, of course." They headed down together. "Well have a good day."

"Thank you Rarity." She opened the door for him where Applejack was about to knock.

"APPLEJACK!" They shouted together.

"Rarity, I was wondering if you saw-" she saw him. "Big Mac? What you doin' here?"

"Umm, well..." Big Mac had nothing.

"Well we're busted Big Mac." Rarity confessed, "Might as well come clear."

"What!" Big Mac was shocked

"What's gonna on here?" Aj asked.

"Your loving brother here was only trying to be nice." Rarity added.

"Rarity please!" Big Mac begged.

"You see your birthday was coming close and your big brother was wanting to get a gift." Rarity cooked up.

"He what?" Aj reponsed.

"Yes, he was going to have me make a fantastic gown for you. So you would look your very best on those special nights." Rarity monologued

"Really now." Applejack looked to her brother.

"Well, umm.." He stared down and kicked the floor.

"Oh Big Mac," She nuzzled his neck, "You ain't got anything for my birthday."

After the shock he nuzzled her back, "Well nothing too good for my Applejack."

They step apart, "Okay then, now me another question." Aj turned to Rarity, "Why are you orange?"

Rarity quickly looked at her hooves. Her coat was still the fruity tint, and soon enough Applejack was comparing their colors. Luckly Rarity thought fast. She crossed her forelegs and said, "I was modeling." Her smile went from ears to ears.

"Rrriight." Applejack said, "Well, Granny left some apple slices and salad for ya, so come on home."

"Right behind ya Aj." He started out but stopped and faced Rarity, "Thanks alot Rarity."

"No problems Big Mac," Rarity waved him off, "I'll start working on the design tonight."

"You know I still got that gala dress." Aj called back.

"That formal wear Applejack." Rarity replied, "These will be more causal."

"Right." Aj turned to walk with her brother.

Rarity sighed heavily. That was close, she thought. Closing the door the she prepared the reversal spell as well her contraceptive spell. She already performed it once a week as instructed, but she alway did it after Big Mac. A stud as powerful as him might overpower the magic. It was ridiculous, but better safe than sound. After her coat was the purest white and mane fabulous violent she head out to grab lunch. Well technically second lunch, because after all a proper lady does not spit.
