Derpy Hooves. She's the mailpony of Ponyville, and it's her job to deliver packages and letters to everypony. Today was especially tough; it was snowing early into the year, so Winter Wrap-Up came early, and Ponyville was a mess. Ponies were scrambling to get everything done, and Derpy had to deliver mail on top of that. What made this even harder, was that she had to deliver more packages than letters, so her back was aching and her wings were trembling with exhaustion. After a long day of work, her loins stirred, causing her some irritation.
The gray mare walked down the dirt path, ponies running past her and apologizing for bumping into her. She forgave them, and trudged along. Although she was tired, she managed to focus on the scenery, rather than the pain in her back, and the heat in her nether regions. She looked at the trees; the leafless sticks were still covered in a think sheet of ice. The white blanket of shimmering snow laid out on the ground, sparkling as the sun reflected off of it. As always, Ponyville was falling behind and hadn't cleaned up the snow yet.
She reached her little grayish house; it wasn't directly inside of Ponyville, but it wasn't as far as Fluttershy's cottage either. Walking inside, she threw the heavy brown mailbag off of her shoulders and onto the light birch wood paneling floor. She lazily went up the stairs into the hallway, and walked a bit forward to her bedroom. Derpy then proceeded to open the door, entering her den and jumping onto her Luna-sized bed. The mare landed face first into the soft mattress, taking a moment to breathe in the scent of herself.
"Uuughhhhh" she grunted into her grayish-purple comforter. Her hooves dug into the duvet, pulling it towards her and bunching it up, then resting her head on the purple lump of soft created from the bed sheets. Her eyes closed, and she smiled as an idea popped into her head.
'Hmmm... It's been quite a while since I've had time to play around down there... Maybe I should just relax and get off...' She thought to herself, slowly reaching a hoof down to her marehood. Derpy slid her hoof over her slit, but she hadn't teased herself, so she wasn't aroused enough. The mare chuckled, and turned around to lay on her back.
Her hooves snaked down to her slightly muscular thighs, then dragged over her soft chest. Derpy's breathing hitched as she reached the two small breasts just above her crotch. The tip of her hoof played with the two nipples, rubbing them lightly. As she massaged the small, perky breasts, she sighed, her nubs growing hard. Derpy used both of her hooves to push the two small breasts together, before giggling and stretching.
She reached her hoof down to her now dripping marehood, and rubbed her clit for a moment. Derpy rubbed over her entrance, enjoying the small 'shlick' noise that her folds made. Her mouth opened slightly as a short gasp escaped, her hoof dipping inside the wetness. The yellow maned mare lifted her damp hoof up to her sensitive clit, and began to rub very lightly and slowly. Another sharp breath followed as she increased her speed, a bead of arousal slipping out of her cunt and dripping down over her tight hole.
Her hoof rubbed faster, making her squeeze her eyes tight as her lower back and pussy started to tingle. Hips bucking, quiet moans left her lips and her wings fluttered occasionally. The pony's hoof rubbed in a circular motion, the tip of it pressing down on the sensitive pearl.
Suddenly, she remembered the the 'Present' Rainbow Dash got her for her birthday. Derpy stopped rubbing and leaned forward, then laid on her stomach to reach the nightstand by her bed. Opening the drawer, she took out an unopened, solid white box. The gray mare opened said box, and took out an object almost shaped like a thinner, shorter stallionhood, a dial placed at the end. Inspecting the lavender, phallic object, she turned the dial and her ears perked as the dildo began to softly vibrate. Although Rainbow Dash had gotten the toy for Derpy as a joke, the gray pony was glad that her cyan friend had gotten her such a lewd object.
Laying back down on her comfy bed, she positioned the latex toy at her entrance, moaning as she felt the vibrations against her dripping folds. Derpy Hooves pushed it inside, smiling as it filled her tight pussy. Slowly, the toy was thrusted in and out; tight, wet muscles clamping onto it. Derpy turned up the dial and sighed, moving her hoof back and forth a little bit faster.
The mattress began to squeak as the mailmare started to pound into her tightness, her wings extended to their full span. She used her free hoof to rub her love button, the pressure in her nether regions beginning to build much faster. Derpy turned the speed on high, and moaned loudly, still thrusting both hooves.
She thrusted the toy in and out of herself as fast as she could, moaning over and over again. The mare started shaking as her orgasm approached, making her move around erratically. Derpy's mind was fuzzy, and she could only focus on the immense pleasure in between her legs; the pleasure that was spreading all over her body. Her legs closed tight as she came, her marecum leaking out and squirting over the toy.
Whimpering and moaning softly, her legs shook as they pressed together tightly. She slowly regained enough strength to let the drenched toy slip out. Derpy moaned as she felt the toy slowly slide out of her, her cunt squeezing the phallus as it retreated. A gasp escaped when the flared head reached the inside of her entrance, causing her to have to ease it out.
She laid down, her head falling back onto her pillows. The toy had just came out of her, and she blushed and bit her lip, moaning as she felt her cream ooze out of her slit, sliding down her hole and forming a small pool at the base of her tail. The femcum seeped into her tail as her breathing returned to normal, a smile forming on her lips.

The gray pony got up off of her bed, and stretched out her relaxed muscles. Grabbing the toy before wiping it off with some cleansing wipes, she walked to her door, trotting out of her room and gliding down the stairs. Derpy went into the bathroom to make herself look, well, like she hadn't just been masturbating. A brush invaded her mane, smoothing out the hair and untangling it.
I think I may need a bath... She thought to herself, glancing into the mirror at her cum covered flank. Bending down slightly, her ass facing the mirror, she raised her tail to the side. Derpy moaned at the sight of her dripping pussy. Her hoof snaked in between her legs, resting on her clit. The appendage slowly moved in a circle, making the owner gasp as she watched her glistening folds stretch with the movement of her hoof.
"Mmnn..." the pony moaned, increasing the speed of her rubbing. The clit winked as it was assaulted, making it's host quiver in delight. Derpy quickly rubbed side to side, watching herself masturbate in the mirror. Her marehood grew wetter as she intently stared at herself. Still sensitive from her last orgasm, her legs began to shake, and her snatch clenched as she gazed at its reflection.
The mare let out a high pitched cry, her hoof moving even faster. Cum squirted from her entrance, splashing onto the mirror that was only inches from her rump. The cum dripped down the mirror, and Derpy breathed heavily, cheekily grinning at the mess she made. Her lips spread, pulled apart by her hoof. The equine gasped as she saw how wet with cum her pussy was, making it drip onto the floor.
Standing up, the horny mare turned towards the mirror. A long, pink tongue slipped out from her lips, and she began licking the squirt off of her mirror, moaning at the tangy taste. The hungry tongue slurped up every drop of marecum off of the surface, until it was clean. She stood on her back legs, and looked at her puffy pussy, admiring how wet and swollen it was before returning to all four hooves.

The mare grabbed some pink bubble bath solution, and set it on the white marble sink. Next, she turned on the hot water, steam rising from the faucet and condensing onto her mirror. She poured the soap into the tub, reaching a hoof into the soapy water and stirring in the bubbles.
Derpy started humming as the tub filled itself, stirring the warm water and pink bubble solution together. The tub was now filled, a mountain of bubbles on top of the water. Turning the water off, she giggled and brought her hoof up, blowing a glob of bubbles off of it.
She stood up, and stepped into the water, watching as a fourth of her legs disappeared into the pink mass. The cross-eyed mare sat down in the tub, enjoying the feeling of her backside being consumed by the warm water. Laying back, she closed her eyes and smiled to herself.
"I'm glad I thought of all this," She said to herself.
She sighed as the water relaxed her even further, her eyes closing as she enjoyed her alone time. Her eyes opened lazily, and she spotted the showerhead, a devious idea popping into her head. She leaned forward, grabbing the nozzle in her hoof. She turned the water on, and switched its flow to the shower, sitting back in the tub. She switched the setting to the jet, and positioned it in front of her snatch, gasping loudly and moaning as she felt the powerful stream on her clit. She held the showerhead tightly, moaning loudly and panting as her clitoris was heavily, mercilessly stimulated. Her back arched forward, mouth hanging open as loud squeals of pleasure rang out.
Derpy's eyes rolled back as her pussy clenched, the pressure on her love button giving her immense pleasure. The mare bit her lip as her legs shook, she was already getting close.
"Mom?" A familiar voice echoed through the house, "I'm home from school!"
Derpy froze, her eyes widening and her moans stopping. The showerhead's strong current of water still tortured her nub as her ears perked, listening for noise. She heard shuffling and quickly turned the water off, standing up to put the shower back up.
"I-I'm taking a bath, Dinky!" She called out, sinking back into the bubbles.
"Oh, okay mom!" Dinky shouted back. She paused for a moment, "Can I jump in?"
Dinky hooves is a small filly, most other foals her age a lot taller than her. It's hard for her to take a bath all alone, so Derpy is usually in the room with her.
Derpy thought for a moment, and hesitantly replied, "Of course, Muffin!" she yelled back across the house. Derpy was still horny, but she toned it down and tried to enter her "Mom Mode."
Dinky galloped to the bathroom door, stopping abruptly and gently opening it with her magic. She giggled when she saw her mother in the tub, a beard of bubbles on her face.
"What? Is there something on my face?" Derpy acted like she was oblivious to the suds on her chin. She laughed and dunked her head under the water, removing the bubbles from her face.
"Mom, you're so silly!" Dinky smiled as she pranced over to the tub, climbing into it.
Derpy smiled in response and started to wash her daughter. She made sure to get all of Dinky's fur wet, and then proceeded onto her mane.
"Mom! I'm _ years old! I can wash my mane!" Dinky pouted, crossing her small forehooves.
Derpy chuckled and ignored her daughter's statement. "How about I wash your mane, and you wash mine?"
"Hmm..." Dinky contemplated, "Okay!"
Derpy continued to rinse off Dinky's mane, then grabbed the shampoo and squeezed some into the filly's blonde mane, smiling happily. She shifted slightly as her foal laid back, Dinky's small flanks resting against Derpy's thighs. Derpy blushed as she silently rubbed Dinky's mane, thinking about how small and cute her little filly is. How innocent she is. How tight and untouched her little fillyhood must be.
Derpy shook her head, trying to stay away from those thoughts, but the thought of her little foal being so curious and inexperienced made her clit throb. She knew she shouldn't be thinking about those things, but with the day she's had, it was hard not to.
"Mom?" Dinky said, breaking her mother's train of thought.
"Yes, muffin?" Derpy replied, snapping back to reality. She saw the mass of bubbles on Dinky's head, "Oh! Right!" The gray pony stood up and grabbed the showerhead, switching it back to normal before turning the water on. She washed her filly's mane, smiling as she did.
"Mom?" Dinky inquired again.
"Yes, muffin?" Derpy chuckled a little; Dinky was always full of questions and eager to bug her mom like any foal her age.
"Today at school Mrs. Cheerilee talked about sex." Dinky said flatly, a hint of curiosity in her tone.
Derpy choked on her own spit, sputtering for a moment and coughing, "She what?"
"She said a stallion puts his peni-"
"Y-Yes muffin I know how it works!" Derpy blushed and turned the water off, putting the showerhead up. She awkwardly sat back down behind Dinky. "Honey, how did she... Explain it?"
Dinky smiled, and said matter-of-factly, "She drew pictures on the chalkboard and told us about them. Hey mom, did you know that a vagina grows twice its size during intercourse?"
Derpy blushed, opening her mouth to say something, but closing it to think. After a moment she nervously replied, "Dinky, did she, uh, show you anything? On herself, or any students?"
Dinky thought for a moment. "Well, no, but she said that its okay to do things to ourselves when we're in private."
The gray pony sighed in relief. If anypony was going to teach her filly with a... Demonstration, it would be herself. An idea popped into her head, one that she knew was wrong. She bit her lip, "Well, have you done anything to yourself, sweetheart?" Derpy blushed as the words left her mouth.
"No, I haven't. Why?" The young filly questions.
"Well, I.. Maybe Mommy should show you how." The older pony replies.
Derpy's daughter contemplated the suggestion, before answering her mother. "I don't see why not..."
The cross eyed made stood up, grabbing the showerhead and turning it to the jet setting, then turning the water on. She sat back down behind dinky and instructed her to lay back. After the filly lays back onto Derpy's chest, Derpy points the showerhead at the young filly's cunt, earning a gasp from her. Dinky watches as the water hits her clit, her mouth wide open.
"M-Mom..." The little filly moans.
Derpy keeps the strong stream of water pointed at the little fillies clit, smiling as she grinds her pussy into Dinky's back. Her clit rubs up against her filly's back, making her moan loudly as the younger of the two gasps. Dinky shakes and moans as she nears her first orgasm.
"Mom! I feel like I-I'm gonna.. Explode!" The little filly's horn starts to spark, and she squeaks out cute little moans of pleasure.
"It's alright muffin, let it happen.." Her mother reassures her, making sure to keep the showerhead in the same place.
The small unicorn squeals as her legs close tight, her body shaking all over. Clear liquid squirts from her pussy, disolving into the water, sighs and gasps escaping her mouth. Derpy takes the showerhead away, and turns the water off. She holds her little filly as she comes down from her first orgasm.
"Wow.." Dinky breathes out, exhausted. She snuggles into her mom's embrace, happy and tired.
Derpy smiles and kisses Dinky on the cheek, then rests her head on the little filly's shoulder. "Love you, muffin."
"Love you too, mom."
