"Uh, Pinkie," whispered Derpy, following Pinkie down to the basement of Cupcake Corner. "I've never done this before."
Pinkie smiled innocently, outfitted in a leather costume. "Me neither! In fact I never knew ponies did this before last month! And mare, am I excited to get started." Last month, Pinkie borrowed a book from the library. The cover looked so interesting, she just had to read it. She was absorbed into the book immediately, then got curious about what it would be like to do those things with another pony. She had chosen the unsuspecting Derpy to be her first experiment, and the mare had reluctantly agreed.
"A-are you sure this is s-safe?" Derpy stuttered, glancing around Pinkie's windowless, makeshift dungeon at the equipment that Pinkie had out to abuse her new playmate. There were chains, belts, a chair, a bed, and something else she couldn't put a name to. There was a single, dim light hanging from the middle of the ceiling.
"Well, duh," said Pinkie, like it was the most stupid question in Equestria that was ever uttered. "Of course it's safe! When have I ever not been safe? In fact, my name should be Safe McSafety Pie. Don't you think? I think so. Last week, when I was foal sitting, I was so safe that I wrapped Mrs. Cake's foals in bubble wrap before I brought them outside! Aren't I thoughtful?"
Derpy took a moment to absorb all of the information she had just heard. "I don't think it's good to wrap foals in bubble wrap. I know you meant good by it, but don't you think that's a little extreme?"
Pinkie huffed, not realizing her terrible mistake. "Are you kidding me? They would probably be dead if I hadn't applied that bubble wrap. That's why they use it on–" Derpy put a hoof over her mouth before she could finish her thought.
"Aren't we getting a little off track? Let's talk about this for a few minutes."
Pinkie took a deep, violent breath in, then slowly let it out to calm herself down. "Okay, first thing's first. Let's establish a safe word. Pick a word, any word."
Derpy's lazy eye slacked off to the side while she though of a word. "Uh, how about muffins?"
"Okie dokie lokie! Next on the list is, uh..." Pinkie squints at the paper she is holding, also moving it closer to her face, in an attempt to read her bad mouth writing. "Sit...bon...dairy...Oh! Set boundaries. We have to set some boundaries. I don't like boundaries, let's skip that step."
In a panic, Derpy exclaimed, "Woah, let's not skip anything! I do have some boundaries I would like you to recognize. First, nothing gross, like, manure." Derpy shivered at the thought.
Pinkie pouted. "Okay...though I really wanted to try that."
Alarmed at Pinkie's eagerness, Derpy took a small step backwards. "Right, so I guess that's all we have to say."
"Wait one minute!" Pinkie put on a rarely seen serious face. "We have to set the scene," she announced.
"Oh, what kind of scene were you thinking of?" Derpy was imagining all the stereotypical scenes that one might find in a BDSM novel.
Pinkie smiled mischievously. "Oh, you know, like maybe you'll be an employee, and I'll be your boss."
Derpy considered this for a moment, then nodded. "Yeah, sounds fine."
Pinkie immediately switched into character. "Ms. Hooves," Pinkie began, somewhat seductively, "One of my other employees has complained about your behavior."
Derpy cleared her throat, and put on her best act. "W-what did I do now?" she asked.
Pinkie took a step towards Derpy. "You know very well what you did. You were trying to seduce my employee, weren't you?"
Derpy looked at the floor guiltily. "Yes, I suppose I was."
Pinkie raised her voice slightly. "Well, I cannot be having that kind of behavior here! You. Are. Fired."
Derpy looked up in shock. "But, ma'am, you can't fire me, I'm your best worker!" Derpy's eyes seemed to frown, like she genuinely believe she was about to be fired.
Pinkie tapped her chin with her hoof, deep in thought, with eyes pointed towards the ceiling to try to find a compromise. Her eyes drift back down towards Derpy. "Well, I suppose there is one thing you can do to redeem yourself."
Derpy looked at the pink pony quizzically. "And what might that be?"
"Oh, you'll see. First, let's have a seat over there." Pinkie guided Derpy over to a kitchen chair, and the pegasus sat down. "Now, close your eyes, and keep them closed." Derpy obeyed. Pinkie got out a rope and began by tying Derpy's legs to the legs of the chair, spreading them far apart.
Derpy's eyes shot open in panic. "W-what are you doing, uh, boss?"
Pinkie looked up, unimpressed. "I told you to keep your eyes closed, didn't I?"
"Yes." The mare's eyes squeezed shut again.
"That's 'yes, ma'am' to you!"
"Y-yes, ma'am." Derpy bit her lip.
Pinkie swiftly tied all of Derpy's limbs to the chair, including her wings, but not so quickly that the ropes were not tied securely. Pinkie stepped back from the chair, looking satisfied. She walked over to a chest in the middle of the room, and retrieved a riding crop.
"What's that for?" asked Derpy.
"If I'm not going to fire you, then I at least have to punish you," Pinkie stated. Pinkie returned to the pegasus's side, and raised the crop. She gently whipped the mare on her thigh. Derpy flinched at the sudden sting.
"Woah, uh stop a minute. I mean, muffins."
Pinkie rolled her eyes. "What is it?"
"That hurt. Sorry, I just was shocked for a minute. Please continue."
"Now, what do your have to say for yourself?" asked Pinkie.
"I'm sorry."
Pinkie, feeling slightly miffed, hit Derpy again, but harder this time. "That's 'sorry, ma'am' to you!"
"I'm sorry, ma'am!"
"How sorry?" Thwack!
"Very sorry, ma'am," Derpy whispered.
"I can't hear you." Thwack!
"I'm very sorry, ma'am!" she squeaked. Derpy felt her skin becoming very sore.
"You'd better be!" Thwack! Feeling her nether regions getting slightly moist, Pinkie decided to step up the game. She traced the crop up and down the inside of Derpy's thigh, and then went back to the chest to get something. She returned to her sub with a blind fold and some clamps. She tied the blindfold tight around the mare's eyes, so there would be no peeking.
Derpy squirmed a little. "This is scary, boss. Please stop."
Pinkie gave a puzzled look. "If you want to see scary, then I'll show your scary. Oh wait, you can't see!" Pinkie giggled at her own joke. "I'll just have to let you feel it then." Pinkie proceeded to attach some clamps to the nipples on Derpy's belly. Derpy felt a burning sensation, and her eyes rolled back in her head from the strange new pleasure. "Nnn..." she moaned.
Pinkie lightly traced the crop up the inside of her victim's thigh again, then hit her. Derpy sqeaked. A corner of Pinkie's mouth turned upwards. "You like that do you? There's more where that came from." The crop went further up Derpy's leg, but not quite touching her vulva. Pinkie massaged her thigh with the crop, then suddenly came down on her with another smack.
Instinctively, the gray pony moaned. "Mmm, boss, I'm so, so, terribly sorry."
Pinkie enjoyed this reaction from her friend, and hit her again, very hard.
"Aaaah!" Derpy squealed.
"You're the one who asked for this, you little..." Pinkie searched her vocabulary for an offensive name to call her playmate. "You little slut."
Derpy could feel her nethers calling out for some attention. "Please, punish me some more. I deserve it for what I have done."
"If you continue like this, I might even give you a pay raise." Pinkie whipped the mare just above her vulva.
"Oh yes, please do," replied the horny mare. "I'll do anything."
Pinkie paused and raised an eyebrow. "Anything?"
"Yes ma'am, anything."
"You know what I want?" Pinkie whispered into Derpy's ear, tickling her.
Derpy shivered. "What, ma'am?"
"Before I tell you that, let's get you a snack. Strawberry or vanilla ice cream?"
Derpy was thoroughly confused, having never done this before. "Strawberry, ma'am."
"Good choice. I'll be right back." Pinkie dropped the crop and went outside the room. Derpy could her her shuffling around in the kitchen. It seemed like an eternity before Pinkie finally returned to the room with a bowl filled with a small amount of ice cream.
"Here you go," said Pinkie, raising a spoon to Derpy's mouth. Derpy cautiously opened her mouth as Pinkie put the spoon in. Derpy felt the ice cream start to melt. Pinkie quickly added, "But don't swallow."
Derpy tilted her her to show her confusion. Pinkie noticed this and answered, "You're going to feed it to me."
Pinkie moved in towards Derpy, and nudged the mare lips open with her own. She began to lick the ice cream out with her agile tongue. Derpy aided Pinkie by spitting the ice cream into her mouth. Pinkie gladly swallowed. When she had finished, she pulled away. "You liked that? Now it's your turn." Pinkie put a spoonful of ice cream in her own mouth, and waited a couple of seconds for it to melt. She french kissed Derpy once again and Derpy obliged by eating the ice cream.
Derpy swallowed then said, "Mmm, delicious."
Pinkie kneeled down to her companion's crotch. She spooned some half melted ice cream into Derpy's vagina carefully, as not to spill any. Derpy moaned from the sudden coolness that spread through out her lower body.
"Now be a good girl, Ms. Hooves, and stay still," Pinkie said, even though Derpy couldn't move if she had wanted to. The pink pony slurped the ice cream from the hole and then moved her tongue across the engorged clit. Derpy started breathing more heavily in response.
"Yes, that's a good little slut," encouraged Pinkie. She kept flicking the clit with her tongue rapidly. When she sensed Derpy's climax approaching, she pulled away quickly to prolong things.
Derpy flinched. "Why did you stop, ma'am?" she asked in disappointment.
Pinkie simply said, "I want you to suffer."
Those words made Derpy feel even more horny, for some reason.
"You have to earn your release, Ms. Hooves. You can do that by eating me out. But first..." Pinkie pulled out a long, beaded string seemingly from out of nowhere.
"What's that?" asked Derpy.
"Anal beads, silly!" said Pinkie, going out of character for a moment.
"Oh, dear me. Please tell me your going to lubricate that first."
"Of course." Pinkie's technique for lubrication was not what Derpy had expected. She slid it into her own vagina until it was nice and slippery. She then spread her partner's soft cheeks and carefully inserted the beads. "We'll leave those in until later." After that was done, Pinkie carefully moved the chair so Derpy was lying on her back. Pinkie crouched down, revealing her southern lips to Derpy. "I'm ready."
"Yes, ma'am." Pinkie moved the leather outfit out of the way. Derpy then proceeded to lick the wet pussy, and occasionally sucking the lips. Pinkie struggled to stay still so the mare could keep going.
"Faster!" urged Pinkie. "Faster!"
Derpy's tongue could not go much faster at this point, but since she was so desperate for her own release, she kept going.
"Oh, yes!" Pinkie groaned. "I'm gonna...nnn!" The juices splattered onto Derpy's mouth. Pinkie waited for the orgasm to subside, then tilted Derpy to her upright position. Pinkie licked her own fluids off her partner's lips.
"D-did I do I good job ma'am?" Derpy stuttered, fearing that she would not be allowed release.
"Oh, yes," said the pink earth pony. "A very good job, indeed." Pinkie playfully nibbled on the ears of the ditzy mare, and licked down inside a bit. The wetness inside her ears caused Derpy to squirm uncomfortably.
Pinkie bent down to Derpy's crotch and started by massaging the lips with her hoof. She tugged on the anal beads still inside of Derpy, twisted them around, and then pulled them out, one by one. As they brushed up against her tight hole, Derpy groaned in pleasure.
Pinkie brought her face in and began eating her out. Pinkie stuffed her entire hoof inside the mare's surprisingly flexible vagina, and pulled in and out, while continuing to use her tongue.
Derpy felt her climax approaching, and could hold on no longer. Pinkie, feeling the walls of her vagina tightening, pulled her hoof out, and Derpy squirted all over the chair, and got some on Pinkie. While Derpy rode out her orgasm, Pinkie made out with her.
Derpy said, "Can you untie me now?"
Pinkie giggled. "I'm not done with you yet, silly filly!" She was not satisfied just yet. Pinkie mercifully removed the clamps from Derpy's nipples. She brought them back the storage chest, and instead brought back an alarmingly large dildo and a gag.
She removed the blind fold from Derpy. Derpy rubbed her eyes, and when she opened them, she saw the gigantic dildo. She gasped in horror. "Pinkie! How is that going to fit inside me?"
"My hoof fit inside of you, didn't it?"
Derpy thought about that for a second. "Yeah, you're right." She then noticed the gag Pinkie was also holding. "What the–" Pinkie had stuffed in the gag before Derpy could say anything else.
"Mrrrh! Mmm!" groaned Derpy in a panic.
"Oh, c'mon now. Don't worry, Pinkie will take good care of you." Pinkie inserted the dildo into her friend's vagina, at first pushing in and out slowly. After a minute, she started speeding up. Derpy struggled to breath through only her nose. Pinkie kept thrusting in the dildo as fast as she could, causing Derpy to have multiple orgasms in a row. Derpy's body shuddered with every single one, causing her to whimper. She didn't pull it out until Derpy looked utterly exhausted. She detached the gag.
"What was that?" cried Derpy. "I thought you'd never stop!" She looked like she was about to cry. Her canal ached from the friction from the constant rubbing.
Pinkie didn't look sorry at all for what she had done. Instead she smiled, pleased with what she had made Derpy feel. She dropped the dildo on the floor, and wrapped her forelegs around the back of Derpy's neck and kissed her gently to calm her down. It appeared to have worked. Pinkie reached down for a moment and untied a single one of Derpy's front legs. She brought it up to her slit. "Do it," she whispered.
Derpy fulfilled Pinkie's desires as Pinkie continued making out with her. Pinkie's hooves slid down to Derpy's bottom, and she squeezed. This made Derpy start to rub Pinkie faster. Pinkie let out a long sigh as she reached climax. Pinkie withdrew her lips from Derpy's. The mares both stopped what they were doing. Pinkie signalled that they were finished by untying the ropes.
When Derpy caught her breath, she said "Can we do this again sometime?"
Pinkie smiled gently, and replied, "Gladly!" Pinkie's face slowly twisted into a grin. She said in a cheerful tone, "Now, who wants cupcakes?"
