Quibble Pants entered the room with slow, methodical steps, being careful not to cause the floors to creak or make too much noise. As careful as he’d come in, he slowly pushed the door shut. When it was finally closed he breathed a sigh of relief.

“Mom fall asleep?” Wind Sprint, who was stretched across her bed on her back, book in front of her, didn’t bother looking up.

“On the sofa, yeah.” The bed sagged as Quibble sat down. She could feel his eyes boring into her, despite her refusal to look in his direction. He stared at her, waiting, hoping for her permission to continue. She liked playing this little game. He was so much fun to toy with.

“I-I couldn’t stop thinking about you.” He continued, breathing heavily, his voice hoarse as he tried to speak as low as possible. The bed creaked as he moved closer, and she guessed he must have been fully erect judging by the scent of his musk that hung in the air.

“Ugh. Fine. Just this one more time.” The filly rolled her eyes dramatically, as if this was the biggest annoyance in the world, like he wouldn’t get off her case about homework or chores.

Quibble didn’t need any more invitation than that, descending upon her in an instant. She barely had time to put a bookmark between the pages and set her book on the nightstand before her Step-Father’s muzzle pressed up between her legs and he spread her with his hooves. He inhaled her sporty, youthful scent and let his tongue droop out, hungrily lapping at her little snatch.

Wind gasped and curled her hooves against the bedspread, trying to hold back her moans as he began eating her out at an erratic pace, tongue slithering inside of her and exploring around her tiny folds. She loosened up for him quickly, giving passage to the intruder who slurped at every inch it could reach.

“Nnng! Quibble, c’mon... You’re gonna make me cum already.” She whined, kicking at his shoulders with a hind leg. He only withdrew when he'd caused her to squeak again, his muzzle dripping with saliva and who knows what else.

“I told you to call me Daddy when we do these things.” He was climbing further up the bed, towering over her. She was dwarfed by his size, and by now she could clearly see his massive stallionhood hanging below him. He was big for his size and certainly knew how to use it. Wind assumed that was what had kept her Mother and him together.

“Ugh.” She groaned again, staring up at him impatiently. She had no time to argue. “Fine. Just hurry up and put it in me ‘Daddy’.”

Quibble seemed satisfied with this as he hunched over and began stroking his member, trying to get himself ready. Wind had squirmed herself backward and propped herself up on her pillows. She caught his gaze and he gestured toward his enormous cock.

“No. No way I’m doing that.” She protested, her eyes shooting daggers at him. Oh, how she loved this game.

“P-please, Windy? It feels so good when you do that. D-daddy will get you anything you want.” He pleaded with her, already positioning himself so that his tip hung in front of her face, wafting her with his powerful musk.

Deliberately hesitant, she shot him one last glare before dragging her tongue up the surface, curling it so as to catch all of his dripping pre. Not breaking eye contact, she opened her maw as wide as she could and settled around the head, letting it poke against the back of her throat. Quibble moaned as her tongue swirled around him from inside her mouth. He wanted to thrust, but she pulled back as soon as he’d gone in.

“Anything?” She narrowed her eyes, tone dripping with seriousness.

“Y-yes, Princess.” Quibble gulped, nodding over-enthusiastically.

Wind went back down on him, slurping him up in her muzzle and coating him in saliva. Needing little help, she began to bob up and down on the few inches she could take, letting his pre-covered shaft tap against the back of her throat while she took her breaths through her nose. Her ears pinned back and her eyes closed so that she could concentrate on her work, going faster and faster as the minutes went by.

Quibble shuddered and planted a hoof on the back of her head, rubbing her mane and gripping her in place. Panting lightly, he gave his hips a light thrust and forced himself into her throat. Wind tried to hold back her gag reflex, but struggled greatly and was soon thrashing about. He pushed himself against her muzzle until he was nearly halfway down her throat, enough that it bulged obscenely from the outside.

He was focusing hard already on not blowing his load right into her stomach. He knew from experience he would never hear the end of that, so with another grunt he popped free of her muzzle, admiring the saliva and pre hanging from her chin.

“Hehe. Sorry, Daddy got a little carried away.” He rubbed the back of his head as he watched his step-daughter sputter and cough.

“You stupid idiot!” She nearly shouted. “You could have knocked me unconscious! A little warning next time would be nice!”

She spread her legs wide for him, little strands of juice connecting from her little fillyhood to her thighs. She had a faint scent of her own in the air. Quibble grinned, knowing the real truth about just how much she enjoyed this.

He plopped down on his haunches and took his member in a hoof, directing himself right at her little cunny, which radiated warmth and was already quivering in excitement.

Wind Sprint’s face was blushing a dark hue. She had to refrain from rubbing herself off, though she knew Quibble would have no objections about seeing that--he’d asked as much from her in the past—but she didn’t want to wait any longer. She needed this.

He pushed himself forward and into her, driving her up against the headboard. She had to grab and bite into one of her pillows to keep from crying out and waking up her mother.

Quibble spared no time in finding a quick pace of humping directly into her. Due to her age they didn’t have to worry about protection and certainly enjoyed that fact as much as they could.

He pumped his hips back and forth, feeling her warm insides squeeze him with such delicious tightness that only served to drive him harder. Deeper and deeper he went, bumping up against her absolute limit, at her cervix just before her womb.

She reached down and rubbed the bulge in her tummy that was moving back and forth, telling her where his fat tip was located inside of her. He caught her toying with him, and grinned.

“Having fun, Princess?” He teased, after a particularly rough thrust.

“N-no!” She sputtered and glared hard at him, though the blush in her cheeks said everything. Her body kept squeezing more and more. She was biting back moans. Her lower lips were absolutely drenched.

“Yes, you are. Are you going to cum soon?” Quibble insisted, wiping his brow of sweat as he humped nearly as fast as he could go. Their hips were making slapping sounds as they met, and her bed was squeaking. Neither really cared about being quiet quite so much anymore.

Wind opened her mouth to respond, to protest on instinct, but instead what came out was a long, drawn-out moan.

“Oooooaaaaaaah!” She squealed, tightening on him, her body jolting.

“Shhh.” Quibble whispered, bending down to peck her chin. A hoof slid up her thighs to her small nipples just above her vulva, and he began to knead them. “Just let it out.”

“G-gaaah...D-daddy!” She arched her back, lifted her hips and let out a howl. “C-cumm-ING!”

Her body exploded like a firework, leaking juices and quivering on him with an iron grip. Seeing the little filly short-circuit like that, and so lewdly, was enough for the stallion. He hooked both hooves around her haunches, pumped himself in a few more times, and nestled nice and deep. His flare expanded and stretched her out even further.

Another loud, low moan filled the air as the stallion above grunted, filling her with his hot seed. Wind Sprint’s eyes rolled back and she lay limp, enjoying the feeling of being used as his personal cumdump for the time being. She’d get back to being her usual bratty self later.

Quibble Pants slowly worked his member out, springing free his half-flared member with a pop. Still unfinished with his orgasm, he erupted again. The sight of the filly laying there, fully fucked and nearly passed out from multiple orgasms, her filly pussy slightly agape, was too much for him.

Shot after shot of his musky horsecum landed on her torso and neck, matting into her fur and painting it white. A couple landed across her face and she scrunched her muzzle in response, eyes snapping open.

“GAH!” She nearly screamed, recoiling and jumping to her hooves. “QUIBBLE! WHAT THE--”

“Ohmygosh, I’m so sorry! I just couldn’t resist. You were so sexy laying like that and I couldn’t resist!” His member still hadn’t subsided, and the view of her staring indignantly up at him with cum dripping from her mane wasn’t helping in the slightest.

“Now I’ve gotta clean this off! You made me such a mess! Ugh!” She hopped off the bed and shot him another glare full of daggers, before trudging out into the hall, her gait wobbly and awkward thanks to her still-dripping cunny and matted tail.

She stormed out of her room and into the hall, using a forehoof to wipe the errant seed off of her face and out of her mane. It only served to make her stickier. What she needed was a good, hot shower. She’d chew his ear out for it later; almost certainly she would receive an extra mug of hot cocoa and snugglytimes as reparation.

Whoever built the house that Wind Sprint and Clear Sky lived in was either a fool, or an incredibly incompetent architect. Upstairs were the bedrooms and a hallway closet; the main floor held the living room, kitchen and only bathroom. In order to get to the bathroom one had to cut through the living room. That was where Clear Sky was supposed to be, dozing in front of the T.V.

Wind Sprint managed her way down the stairs without so much as a squeak in the steps, and trotted wobbly into the living room. The light of the TV was casting shadows on the wall, causing Wind to jump. She slowly walked in front of the sofa, when a voice caught her attention.

“Oh, Windy, you’re awake. I wondered what all that noise was. Have you seen Quibble?” It was Clear Sky, standing directly behind her, in the doorway to the kitchen, a bowl of popcorn in her magical aura.

“Mom!” Wind whirled around and tucked her tail between her legs to cover her gaping vagina. She winced as it immediately matted into her tail. She hoped she hadn’t seen anything.

“Last time I checked, that’s who I was.” The mare laughed to herself as she sat back down on the sofa. “What are you doing up so late?”

“I, erm, I was....” The filly went pale, trying to find excuses, backing her way toward the wall. “Just going to the bathroom! Yeah!”

“Of course, I can see that, silly filly. But I meant why are you up. It’s a school night.” She gently chided, eyes glued to the girl who was only trying to make herself look smaller, hoping beyond all hope that her mother wouldn’t notice her messed-up mane or matted fur.

“Wind? What’s wrong?” Clear leaned forward and suddenly went wide-eyed. “Oh, sweetheart, your mane! Oh my goodness, did it happen again?”

Wind gulped audibly. She was dead meat. She’d been figured out. Quibble would be locked away forever and she’d probably be sent to a boarding school for bad behaviour. Her mother sprung off the sofa and advanced on her, and just when she thought she was about to receive the reprimanding of her life, Clear pulled her into a swift hug.

“Nightmares again, huh? I know, they’re the worst, but I promise you the Headless Horse can’t come and get you. He’s just a folk tale and isn’t real.” Clear reassured, patting her filly’s head and smoothing out her mane. “You’re all sweaty! Must have been a real doozy. You poor thing.”

Wind couldn’t believe her ears, but was too afraid to say otherwise. Her mother was currently pressing her against her chest, unaware that she was covered in the seed of her lover. Clear took a whiff of the air and Windy shut her eyes tight, thinking about how this couldn't get any worse.

“My my, you certainly smell like you need a bath. I see why you’re up. Would you like me to help wash you, just like old times? It can be our secret.” The mare cooed, smooching Wind on the cheek.

Wind recoiled and desperately tried to get out of her iron grip. If she didn’t get to the bathroom soon, there would be a puddle under her as the juices continued leaking out of her. That was if her Clear didn’t catch on first.

“No! I mean, no thanks Mom, but I can wash myself.” She succeeded in worming herself out and quickly squirmed a few steps away. Her mother gave her an odd look, one eyebrow raised.

“You’ve never turned down bathtime before.”

“I-I know, Mom!” Windy stammered. “It’s just that I’m tired and want to have a quick one. See you later!” Windy quickly kissed her Mom goodnight and pranced into the bathroom.

Clear snickered as she watched Wind scamper away, calling out just before the door closed.

“Remember to wash behind your ears!”
