Daddy Doesn't Disapprove

Diamond Tiara was at home one evening, feeling horny. As a little kid she'd never welcomed her father's sexual attention but as she'd approached puberty and started to develop urges of her own, that was precisely when he'd started to lose interest.

Her stepmother, Mayor Mare, was working late at the town hall and it was Randolph's night off, so she went to see Filthy Rich in his study where he was doing the accounts for Barnyard Bargains. "I'm horny," she told him. He looked up from his work. "So what are you going to do about it, daddy?" she asked.

"Nothing, Diamond," he said, "you can sort yourself out, can't you? I'm busy and you know I don't think we should do that any more. It's not right."

"Yes… what would your new wife think?" Diamond gasped. "If she found out that you'd been fucking your own daughter? If she knew that the night before her wedding you'd been in bed with her future stepdaughter?"

"You wouldn't," Filthy said.

"I might," Diamond answered.

"She'd never believe you."

Diamond smiled at him. "I could give her a very detailed description."

Filthy Rich stomped his hoof. "Fine. But this is the last time," he said.

"Whatever!" Diamond huffed.

Diamond led her father upstairs. Instead of turning left at the top of the stairs towards her own room she turned right towards the master bedroom.

Filthy Rich seemed hesitant. "Can we do it in your room?" he asked.

Diamond looked at her father. "Why?" she asked. "Do you like fucking me in my pretty pink bedroom with all my Disneigh Princess posters on the walls. Does that turn you on?"

"I just… I just thought… you know… if your stepmother comes home early then…"

"Fine!" Diamond groaned and headed towards her own bedroom. She knew that was a risk. She didn't want Mayor Mare finding out any more than he did; that would put an end to all their fun.

She sprung onto the bed and rolled onto her back, opening her legs and showing her pussy which was already wet. "Go on then, dad. You know what I like," she said.

Filthy Rich got on his knees between his daughter's back legs and used his hooves to part her pussy lips. Diamond Tiara pushed his hooves aside. "Beg first," she commanded.

Filthy huffed. "Please may I lick your pussy?"

"You know what?" Diamond asked. "I'm not really feeling your enthusiasm. Maybe I need to compare notes with your wife. See whether you're more enthusiastic with her than you are with me?"

Filthy panicked. "Please may I lick your beautiful pussy, Diamond? I long for its sweet taste. I'd do anything just to—"

"You may," Diamond smiled and Filthy calmed down. "And don't worry. I was only joking. I know you could never be enthusiastic about her."

Filthy hated the hold his own daughter had over him. He hated how being with her made him feel the next morning. But Mayor Mare was always too busy for anything physical these days, and he felt his cock harden thinking about the possibilities that this evening would bring.

His tongue lapped at her sweet pussy lips then he pushed his oral muscle inside her tight crack. His marriage to the mayor might have been convenient for business reasons, and — okay — she was still kind of hot for her age, but Diamond's little pussy was perfect in every way. It tasted of strawberry marshmallows.

Diamond wrapped her back hooves around the back of her dad's neck while he sucked her little clit. She used her legs to pull him in closer, so that his muzzle was buried in her pussy.

Filthy Rich sucked hard on Diamond's pussy, his tongue flicking at her clit. He used his front hooves to stroke her inner thighs.

"Not too fast, daddy," Diamond sighed as she held the back of her father's head. "I want it to last this time."

Filthy Rich broke away and looked up at his daughter. "Okay, sweetie." He switched to lapping at her outer folds, giving her sensitive clit a break.

Hmph, that's 'Mistress Sweetie' to you, Diamond thought to herself. The aggravated thought soon vanished from her mind as the tip of Filthy's tongue began to probe the entrance of her silken gap again, making her squeal in delight.

Filthy Rich was ashamed to feel his cock harden at the sound of Diamond's squeals. His tongue circled around her pussy, starting at the outer lips, and spiralling inwards, back towards her hole. He extended it as far as he could, dipping it into her passage and fucking her with it.

Overwhelmed by the waves of sexual pleasure flowing through her body, Diamond instinctively began to rock her hips slowly against Filthy's tender lips, making his tongue plunge deeper into her.

Filthy thrust his tongue in and out in time with Diamond's movements, enjoying the sweet taste of the juices that were starting to flow from her pussy. His cock was so hard it was starting to ache for release, and he responded by rubbing it against his daughter's mattress.

More and more of Diamond's irresistible juices seeped into Filthy's mouth and down his throat. She grabbed a part of her father's mane in her hooves began lightly tugging on it, encouraging her Filthy to keep going. Already, she knew an orgasm would be here soon.

Filthy could barely breathe with his face buried in Diamond's pussy. He knew he had to make her cum fast. He reached one hoof up, running it through the soft fur on Diamond's belly and soon found her nipples, moving his hoof from one to the other, and rubbing them gently while he continued to tongue-fuck her pussy.

"Da–daddy!" Diamond cried, thrusting down onto Filthy's tongue. The top of his muzzle began to stimulate her clit, which only brought her closer and closer to her climax. Diamond's tight pussy walls were beginning to contract around the stallion's oral muscle.

Filthy Rich grunted, thrusting against Diamond's pink sheets. It felt so good, but he needed to slow down. Diamond wouldn't be happy if he climaxed already. Filthy scraped his top teeth over his daughter's clit, hoping it would send her over the edge. Diamond arched her back forcefully, gripping her sheets with her forehooves. Her pussy walls clamped down on Filthy's tongue as her orgasm took over. A wave of sweet nectar like cum oozed out of the filly's pussy and onto her dad's waiting tongue.

Filthy sucked up every drop. He knew Diamond hated it when he wasted any, plus he had to admit, it tasted pretty good. Besides which, he didn't really want his wife discovering cum stains on his daughter's sheets — that could lead to… questions.

He allowed her to ride out her climax on his tongue before gently licking the area clean and kissing his way up her body, towards her mouth, paying special attention to her little nipples along the way. Diamond's hind legs twitched and quivered in lust as her father's belly fur lightly brushed over her now semi-sensitive clit. She looked down into Filthy's eyes and smirked. "Did you enjoy tasting your princess' petite perfect pussy?" she laughed half-heartedly.

Filthy nodded wordlessly before leading in to kiss Diamond, letting her taste her own pussy on his mouth. The tip of his cock pressed against her thigh and he longed to start rutting her. Diamond pulled away from the kiss for a moment a snickered. "Oh, so daddy does want to fuck his little girl now, does he?"

Filthy looked down at Diamond's belly, not wanting to meet her eyes. "Yes, Diamond," he mumbled.

Diamond lifted one of her hind legs, and allowed her hoof to rub up and down Filthy's solid, thick shaft. "What was that?"

Filthy shuddered at the feel of Diamond's hooficured lower hoof against his erection. He spoke a little louder. "Yes, Diamond, I want to fuck you." He paused. "Please?"

"Alright then, daddy, but I have some rules," she said softly, continuing to stroke her dad's throbbing cock.

Filthy pressed his member harder against Diamond's hoof. "Yes, princess," he answered, nodding.

"Rule number one: when fucking your little princess, you must complement how amazing she feels," she said, pressing his shaft firmly against her belly. "Rule two: no closing your eyes — I don't want you thinking of her. And rule number three: you are not allowed to cum before me. I cum first." Diamond realigned Filthy's cock up with her pussy lips again. "Fail to follow these rules, and I may have to tell your dearest wife everything."

"Yes, princess," Filthy said, nodding his head again. Rule two would be easy — he'd never think about his wife when he was with Diamond — to tell the truth, he usually thought about Diamond when he was with his wife. He didn't quite know how he'd be able to follow rule three — his cock already ached, begging to cum, thanks to Diamond stroking it up and down.

Diamond smiled then nodded. "Good daddy. You may begin." She moved her hind legs apart slowly.

Filthy pressed the head of his cock up against his daughter's already-wet pussy and pushed his hips forward. After a moment's resistance, it gave way and the head slipped inside, stretching her lips. Diamond squeaked quietly as every inch of his shaft stretched our her little pussy. Despite frequent use for years, Filthy thought Diamond's pussy still felt as tight as it did when she was little.

He kept his eyes trained on Diamond's lower quarters while he eased the rest of his shaft inside her. He could see the faint outline of his cock bulging her belly under her soft pink fur. Diamond held her breath as she became accustomed to the tight feel like she had many times before. She moaned out longingly, then pressed her head back into the cushions.

Filthy started slowly moving his shaft in and out of his precious Diamond's pussy. Though he longed to rut her hard, he knew that would give him speedy relief and this time he needed to last longer than her — that was her rule, and he had to obey — or try to.

"Mmm… how does it feel, daddy? Fucking your little princess is wonderful, isn't it?" Diamond cooed, moving a hoof down to play with the erect nipples on her teats, brushing her fur over them lightly.

Filthy nodded and looked up into her eyes. "Diamond, you know my objections have never been about that. You're… you're the best."

Diamond leaned forward and pecked Filthy on the lips. "That's a good daddy."

Filthy looked back down at Diamond's body, watching her fondling her nipples while the bulge caused by his rock hard member moved up and down her belly, like an animal moving under her skin.

Diamond Tiara let out a series of little moans and groans. She knew she could get anypony in Ponyville to fuck her, but none of them would be as powerful, or as experienced as Filthy Rich. Sure, Pipsqueak was a fun, fast fucker, but he always came too fast, and his name was… errr… kinda deserved. Sweetie Belle was one hell of a ride when it came to oral. They each had their own unique ways of making Diamond cum, but neither would ever come close to being as perfect in bed than Diamond's own dad.

Filthy felt a climax beginning to build up in his loins. He needed to slow it down, or speed Diamond's up. He changed pace slightly, and leaned in to nibble at her ears.

Diamond pressed her forehead into her Filthy's chest, and began licking at his fur, showing him her gratitude. She lay her hoof on top of her bulging belly. Moving her hoof back and forth, feeling Filthy's shaft twitch inside her, brought more pleasure though her and Filthy's bodies. She applied pressure to her tummy, making sure it was rubbing deep into the head on the older pony's cock.

Filthy grunted, the hoof massaging his shaft through the thin walls of Diamond's tummy adding an extra layer of pleasure. He needed a change of pace if he wanted to avoid spilling his seed inside her too soon. He pulled out of his daughter's pussy and used his forehooves to roll her onto her belly. Mounting her from behind, he entered her again, and slowly fucked her while sliding one forehoof over her flank and under her thigh, seeking out her teats.

Diamond gasped and was about to complain about her father's position and pace change, but as soon as his hoof made contact with her firm, bouncy teats, she pushed her face into the bed sheets and cried out in muffled moans. She leaned back further onto his cock as she began to feel a second orgasm build up deep within her tummy.

Filthy Rich alternated between caressing his daughter's nipples and massaging the outer folds of her pussy. He gritted his teeth, burying his face in the back of her mane to try to hold off from cumming.

Desperate for a release, Diamond sought out her clit. Her whimpers grew louder as her pussy walls began to constrict Filthy's cock, like they had done before with his tongue. She bit down hard on her bottom lip and concentrated on rubbing her clit faster and faster.

Filthy felt Diamond's hoof go for her clit, and put his own hoof on top of hers in encouragement, helping her rub it. From her sighs and rapid breaths, he could tell she was close to climax — somehow, miraculously, he was going to be able to make it — he was going to be able to outlast his daughter.

He nibbled on the back of her neck, a move he knew she loved.

Diamond's body tensed as Filthy thrust into her pussy a few more times, sending her over the edge and reaching her climax. Another, yet more intense, stream of cum came gushing out of Diamond's pussy, coating Filthy's crotch and cock.

Diamond's climax made her already tight pussy constrict around Filthy's shaft. His urge to rut her became overwhelming, and now that he had permission to cum, he didn't hold back. Filthy held his daughter's flanks with his forehooves and thrust into her as hard and as fast as he could. His stallionhood penetrated her so deeply that if he hadn't done this so many times before, he'd worry about damaging her.

The mare's tongue lolled out of her, and she panted heavily, still focusing on riding out her own orgasm. Her clit rubbing slowed down as she let Filthy fuck her quivering cunt, feeling his stomach slam against her squishy little ass, and hearing the slap of sweaty fur against sweaty fur.

Filthy felt a tension building up inside him and gritted his teeth to concentrate on the sensations he was feeling. He'd promised Diamond he'd keep his eyes open, so rather than closing them, he watched her lavender mane bouncing with each thrust of his cock.

Diamond looked back at Filthy through half-lidded eyes and whimpered softly. She could hardly wait for the deep heat in her belly to be extinguished by Filthy's seed filling her insides. She leaned her head back as far as she could and kissed Filthy passionately on the lips, then whined softly, "Please, daddy… cum inside me…"

Hearing Diamond beg for his cum was enough to push Filthy over the edge. He slammed his hips against her rear, burying his cock in her and groaning as his balls emptied a huge load of sticky semen — the build up of several weeks without sex — deep inside his daughter, causing her belly to swell up even more than the bulge his large stallionhood had caused.

Diamond twisted her neck and threw her head back onto the bed sheets, looking up at the ceiling, panting heavily and releasing a large sigh of relief. Cold shivers flowed through her body as little drops of cum dripped out of Filthy's shaft into her spent pussy. She felt her body grow limp and start to relax.

Filthy pulled out, his softening stallionhood flopping onto Diamond's pink bedsheets. He crawled up onto the bed to lie beside his daughter and catch his breath.

Diamond Tiara turned her head to looked over to her dad, smiling tiredly. Her breathing slowed down to its normal state. She held her muzzle close to her dad's and kissed him softly on the lips as she felt her seed-inflated tummy begin to shrink, cum slowly seeping out of her pussy and onto her tail and pretty pink bed sheets.

Filthy kissed back and ran a hoof through his daughter's sweaty mane. Finally breaking away, he sighed and murmured, "that was amazing, sweetie."

"I know I am," Diamond sighed, nodding. She tilted her head for a moment, remembering something. "Daddy, did you remember to follow all three rules?" she asked.

"Of course, honey," he answered, trying to recall exactly what they were. He kissed her softly on the cheek.

"Oh, really?" Diamond smirked. "I don't remember you complimenting me on how wonderful I was as you were fucking me my tight little filly pussy."

Filthy spluttered. "I… Diamond, I'm pretty sure I—"

Diamond cut Filthy off by planting a deep, yet soft kiss on his lips, then pulling away and giggling softly. "I'm kidding, daddy. I wasn't even going to tell her anything in the first place. Can't ruin your reputation, now can I? Where would I get all of my jewels and money?!" she exclaimed.

Filthy growled and climbed out of bed. Spotting the mess they'd made of the sheets, he gestured with his hoof. "Get up, Di. I'll need to clear that up."

Diamond pouted, wanting to lie down for a little longer. She got up anyway, knowing that if she left her bed sheets the way they were, both she and her dad would be out of the streets faster than she could blink. Well… that's what she thought, at least.

Filthy Rich stripped Diamond's sheets, sodden with sweat and cum, off the bed and carried them down the stairs to the small laundry room at the back of the house. As he was closing the door on the washing machine, he heard a key turning in the lock at the front of the house.

Mayor Mare trotted into the house and closed the door behind her. "Riiichy~" she called out across the hall, "I'm home."

Filthy Rich hurriedly turned the dial on the machine and was rewarded by the sound of water flowing. "I'm just putting a wash on, honey."

Mayor Mare peered into the laundry room, seeing her husband there. She walked inside and smiled, with a slightly confused look spreading across her face. "You're doing the laundry?" she asked. "This is new. What's the occasion?"

Filthy grinned sheepishly. "Just trying to do more to help out around the house. I know how busy you are to the moment."

"Awww," Mayor cooed, then leaned forward to quickly peck Filthy on the lips. "You're such a wonderful husband."

"I try my best." Well, I have been working very hard this evening.

"Splendid." Mayor Mare made her way to the door before turning around one last time. "Oh, darling?"

Filthy Rich raised an eyebrow. "Mhmm?"

"I love the taste of your lips today. Tastes like strawberry marshmallows. New lip balm or something?" She left the laundry room without another word.
