Rainbow Blaze played rather sordid games with his daughter when she was a filly. But now she's all grown up, surely she wouldn't want to play them again...?

Rainbow Blaze is incredibly proud of his daughter. Why wouldn’t he be? She’s a Wonderbolt, and friends with a powerful princess! But despite her lofty new life, Blaze can only hope she still has space in her diary for him. And when she comes home to visit one day, he gets exactly the answer he was hoping for. Now, all he needs is a rather powerful ‘growth potion’ to help the magical evening along...

“So Kid, how does it feel to be a part of the Big Leagues now? Friends with a Princess, a member of the Wonderbolts... hoo boy.”

Rainbow Blaze smiled softly at his daughter, sat quietly beside her. The two were perched on the edge of a cloud, watching the beautiful majesty of a Cloudsdale sunset. Princess Celestia’s magic was one thing down on the surface, but up above the clouds, it was awe inspiring. Rainbow Dash chuckled to herself as her father trailed off.

“Yeah Dad, it’s pretty damn sweet! Though it all gets pretty hectic sometimes, what with Spitfire AND the Cutie Map giving me orders, I don’t get much time to rest… That’s why I wanted to drop in, spend a little time with my old man!”

She playfully jabbed a hoof into his side, giggling again as he exaggerated a recoil in response. Settling down, Rainbow Blaze couldn’t help but sigh to himself, staring out at the orange sky before him.

“What’s up Dad? Something got you down?”

Blaze glanced over at his daughter, stopping for a moment to stare into her beautiful eyes. He gave her a warm smile before responding.

“No, nothing major, dear. It’s just, well, I just feel so proud to have a daughter as talented as you! I’ve never been that good at anything really, so you make me feel complete. I just want you to remember that, no matter where you go, your Mother and I will always love you…”

He trailed off as his daughter leaned in close, squeezing him in a rib-crushingly tight hug. For good measure she planted a warm kiss on his cheek, staying there for a few seconds before pulling back.

“Thanks Dad, it makes me feel so good to hear you say that! I love you too. But as for that ‘no talents’ thing you were spouting earlier, I won’t be hearing it! You have some very impressive talents, you always used to show them to me when I was a filly! Some very, very,” she paused for good measure, before leaning in to whisper into his ear. “Special talents.”

She pulled away, smiling coyly as she watched the cogs in her father’s brain whir. To be quite honest, she would have felt a little offended if he couldn’t remember, but she knew he’d got it when his eyes lit up, and his cheeks went red.

“O-Oh, yes… er, those talents. Honey, I haven’t done anything like that for years, and frankly, it embarrases me rather for you to even bring it up again. I used you, took advantage of your naive mind and my position of authority...”

He had stopped watching his daughter, and instead taken to staring at the huge void beneath his feet. He wished he could be one of those little specks down there, going about their evenings, none the wiser to the embarrassing family troubles up above. As such, it caught him rather off-guard when his daughter scooched up closer to him, placing a hoof on his thigh.

“Dad, you don’t need to be embarrassed about what we got up to when I was a little filly. Yes, it was your idea, but that doesn’t mean you used me… I loved every second of it! It made me feel so loved, knowing how much you enjoyed being inside me. I’d never experienced anything like it, and quite frankly, I haven’t experienced it since…”

The tip of her hoof began slowly running circles over the top of Rainbow Blaze’s leg. Rather dumbfounded, he wasn’t sure quite what to say. Deep down he was utterly relieved at his daughter’s approval, and quite frankly, quite excited to hear he was the best she’d ever had.

“Y-You don’t really mean that, do you? All those strong stallions that drool over you as you fly overhead, in your... tight, revealing uniform…” His mind - ashamedly - began to drift as such images quickly filled his head. He felt his loins beginning to shift as the pictures danced through his imagination, though it could’ve been related to his daughter’s southward bound hoof.

“Of course I do, Daddy. You filled me up with so much of your spunk I could barely walk or fly… no other stallion I’ve been with has even come close to matching your... ability.”

Rainbow Blaze yelped a little in surprise as he felt his daughter’s hoof make contact with his balls.

“Mmmm,” Rainbow Dash moaned, biting her lip. “Daddy, they’re so heavy… how can you not be proud of them? Say…” she stared her father deep in the eyes, her face the picture of mischief, “Why don’t you show me what they can do again? Just like old times, eh?”

Rainbow Blaze watched as his daughter slowly dipped her head down towards his privates, mouth sliding open in anticipation. Despite the eagerness of his special mare - and his own eagerness to pound her senseless - he took a hold of her cheeks, holding her still. She looked up into his eyes, licking her lips. Rainbow Blaze gulped at the sight, feeling his cock begin to twitch in its sheath.

“I-I don’t think we should do it here, honey… ponies going about their evenings might see. Why don’t we go back home? We could even go play in your foalhood room - it’s just as you left it.”

The middle-aged stallion was already clambering to his hooves, not really waiting for an answer. He didn’t want to admit it, but he didn’t feel like he was ready just yet. He had to go home to get himself into the zone. His daughter watched him stand, pausing for a moment, before climbing to her hooves too. She nodded approvingly, spreading her wings. The two took to the sky, cruising towards the house.

* * * *

Rainbow Dash slowly pushed the door open, fumbling against the dark wall for the light switch. Eventually she made contact, flicking the switch into position. The room was bathed in light, and Rainbow was quickly taken back to her foalhood. Everything was how she remembered it - Wonderbolt posters all over the walls and ceiling, along with custom rainbow-themed furniture. She’d never appreciated it as a foal, but this stuff must have cost her parents a heck of a lot. Trotting into the room, she flopped down onto the bed, resting on her back. Her father had told her to wait for him, to make herself comfortable - which was exactly what she did.

Meanwhile, in the other room, Firefly also lounged on her bed. But while her daughter was full of heady lust and anticipation, Firefly was a little angrier, and more than a little disappointed. She idly watched her husband - head buried in a closet - as he rummaged through it. Clothes were occasionally flung from over his head, only to fall in a crumpled pile behind him. She rolled her eyes as he withdrew, eagerly clutching a small cardboard box. Dropping to the floor he tore the box open, scooping out a small glass bottle in his teeth. A label was wrapped around the neck of the bottle, with the message

Twilight Velvet’s Stallion Expansion Solution - Liquid Magic!

“I’ve had those bottled growth spells sat in the cupboard for years now,” Firefly hissed, “and you never once wanted to use them with me. After the last debacle with you and our daughter, I told you what would happen. I told you that you had to worship me, or else I’d unleash Twilight Velvet’s growth spells on you. And yes, you kept to my instructions, so I never had to use them. Since then, how many nights did I suggest we broke them out and played with them, only for you to say ‘no, I want to save them for a special night’. And now it turns out that special night is the night your daughter comes back home, so you can relive those sordid games you used to play with her.”

Rainbow Blaze moved towards his long-suffering wife, hooves outstretched. Ignoring his token efforts to be affectionate, Firefly crossed her hooves in a sulk.

“Go and do what you need to do to our daughter, AGAIN. Just know I’m disappointed in you. I thought you were past all this, but clearly I was wrong.”

She huffed exaggeratedly as he approached, throwing her gaze away towards the ceiling. She had a point to make, and when she did, there was no reasoning with her. Resigned to the inevitable future arguments, he picked up the glass bottle between his hooves. On the inverse of the label, hidden away, was a little piece of fine print:

PLEASE USE RESPONSIBLY, RECOMMENDED SINGLE DOSE TWO CAPS WORTH.

“I’m sorry you feel so bad about this honey,” Rainbow Blaze started, before necking the entire contents of the bottle, “I really am. I promise I’ll make it all up to you. Say, why don’t I go ask Mrs. Velvet to whip up some more batches of this stuff after work tomorrow, and then we can spend some proper nights together. How about that?”

His wife ignored him. She was good at that. Realizing there wasn’t much else to say, Blaze lowered his head slightly before ducking out of the room. Once out of his wife’s sight, his pace picked up from a trot to a practical gallop as he surged down the hallway. More memories of those old games flashed through his mind, but now with none of the guilt he’d felt before. He knew how much his daughter had enjoyed them, and he knew she would enjoy them again now.

There it was. Dash’s foalhood room. The Wonderbolt logo still proudly emblazoned on the door, just another memory of their daughter Firefly and Blaze hadn’t been able to throw away. Approaching the door he slowly pushed it open, peering around the small crack. There she was, waiting for him.

He could feel his cock sliding free from its sheath the moment he entered the room. There she was, lying on her side, presenting her rear towards him. Their eyes locked as he approached, and again she licked her lips in that most teasing way.

“Sweet Celestia’s, she a little minx…” Blaze thought to himself as yet more blood rushed to his nethers.

She rolled onto her back before parting her legs into the air, exposing her genitalia fully. Blaze stared down at the wonderful sight, thanking the stars he was so lucky. Even now, she was as tight and immaculate as she had been all those years ago. Lowering himself down onto the bed, he crawled towards his daughter on his knees, sliding between her legs, coming to rest above her. He looked straight down into her eyes, watching her face light up mischievously. In an effort to tease the mare that little bit more, Blaze let his stiff rod brush against her exposed pussy, coming to rest between its warm folds. He was about to speak, but his Rainbow Dash spoke up first.

“Daddy, I don’t want you in my pussy tonight… well, I would do, but I want you in my ass much, much more! That’s where you longed to be when I was a foal, and it’s where I long for you to be today. But first, do you think I could warm you into it a little?”

Rainbow Blaze nodded dumbly, simply over the moon to be getting such attention from a young mare so beautiful again. Rainbow Dash chuckled.

“In that case Daddy, roll onto your back for me, I want to play with your balls a little… after all, you so rudely turned me down when we were out watching the sunset.”

She made an effort to pour emphasis into ‘rudely’, most likely as a naughty dig or joke at her father’s expense. Blaze thought to himself as he loyally repositioned his body. He kind of wished he had taken advantage of her rather forward ‘offer’ outside, the rush would’ve been rather fun. But if they’d been caught he could’ve gotten the two of them into a whole world of trouble. Imagine if it came out that a member of the Wonderbolts had sexual relations with her own father?! The tabloids would be all over the story, and poor Dash would never live it down. No, best to protect her dignity and play their games in private.

Thinking of privates, Blaze was snapped back to reality as his daughter positioned one of her hooves under his ballsack. She held there for a moment, before lifting his testes slightly, cupping them in her hoof. Leaning forwards, out from between her lips poked that little pink tongue, pressing deep and firm into the wrinkly skin of his sack. Leaving one hoof behind him on the bed for support, Blaze began to slowly run the other through the mare’s mane, pausing to take in it’s soft texture.

Suddenly though, all that had to stop. A searing discomfort had torn through his abdomen, heading southwards towards his crotch. The pain loitered for a second, before shooting into his testes. Blaze began to grunt and moan through gritted teeth, jerking forwards. He rested his hoof on his daughter’s shoulder, who had stopped her fondling and focused her attention on her father’s well being.

He watched Dash’s pained expression of concern, before it morphed into one more of alarm. Her body lurched downwards ever so slightly, and her eyes began to widen. Blaze followed her gaze, which had come to rest on his genitals. His testes had swollen in her very hooves. But not to some trivial extent. Dash gasped with shock as they expanded, settling down once they’d grown to thrice their normal size. While Dash before had easily lifted both in one hoof, she found herself unable to lift even one without considerable effort.

“D-Dad, what in Equestria did you do? This is insane!”

Rainbow Blaze chuckled, trying to act nonchalant. He didn’t want to let on to the fact he’d had no idea his balls would grow THAT large, and that honestly, the whole event had freaked him out a little.

“I know right? You’ve got Twilight Sparkle’s mother to thank for this kind of growth magic…” He rested his hooves against his daughter’s cheeks, both of which had grown adorably red. “...and you’ve got her to thank for the sensations that are about to wash through you.”

With little pause for thought, he guided his daughter’s face down onto his impressive rod. He twitched slightly as her puckered lips softly kissed the top of his shaft, continuing to work as his flare rapidly expanded. It continued to bump and rub against Dash’s face as she worshiped it, planting wet, sloppy kisses along its length. Then she pulled her head back, pausing above his cock. She opened her mouth wide - exposing a web-like lattice of spittle across her teeth - before slamming her head down onto him. Clearly those raucous, alcohol-fueled Wonderbolt post-show parties had led to Dash becoming quite the sexual expert. Blaze didn’t like to think of the other stallions that had inevitably been inside his daughter at some point. Partly his fatherly instinct, but also, admittedly, a little jealousy. Still, he had her again now, and boy was she making up for lost time.

Dash had none of the hesitancy or concern she’d had as a foal. Now she worked tirelessly, jerking her head back and forth at lightning pace. Blaze watched his cock rapidly vanish and reappear from his daughter’s mouth, unable to do much beyond grunt and groan. He’d been caught off guard by Dash’s monumental ability, and the sheer pleasure of her body. Despite the male Wonderbolts surely being very familiar with her privates by now, she was still as tight as the first time. Blaze’s flare occasionally expanded again, dragging forcefully against the walls of Dash’s throat. She would splutter and moan in response, but bless her, she still worked her father raw.

Blaze’s orgasm was rather unexpected. Perhaps his mind had been focused on her, maybe the potion had affected his sense of feeling somehow. Either way, a huge pressure had mounted inside him - one he knew he wouldn’t be able to withhold. Yelling out, he wrapped his hooves around the back of his daughter’s head and neck, smacking her down against his crotch. The sudden ferocity of it caused Dash’s eyes to water, trying to pull back in order to recover. But there wasn’t time.

The flow of spunk was sudden, massive, and constant. A thick, seemingly never-ending rope began to fire free from his urethra, barraging the back of her throat before slipping down her gullet. Dash could feel Blaze’s balls churning violently as her chin rested against them. The suddenness of the orgasm had caught Rainbow Dash severely off-guard - she’d involuntarily taken a deep breath just as it begun. Spluttering and wheezing pathetically, she could feel tears beginning to pool in the corners of her eyes. But being a silly little filly wasn’t going to make it stop, and she had a reputation to uphold. Steeling her resolve, Rainbow braced herself against her father, clenching her hooves against his flanks. She didn’t need to worry about swallowing the torrent of liquid, as her father’s flared cockhead was lodged deep down into her throat. With slow, methodical breaths, she managed to get her intense splutters to cease, meaning Dash could ease into the rhythm of her father’s bone-shaking orgasm.

But despite the ceasing of Dash’s splutters and her newfound calm, the room was anything but peaceful and relaxed. The room was in fact a veritable orchestra of noise.

Blaze grunting and squeaking like a stuck pig as he focused his concentration.

The creaking of the bed-springs beneath the two sordid lovers as they excitedly moved about.

The contents of both his balls and her belly audibly sloshing, the spunk inside churning like waves.

The slight, bizarre creaks of Dash’s body has her belly was forcibly expanded by the onslaught of batter.

Blaze moaned something incomprehensible. If Dash were to guess, she’d presume he’d said the ungodly load was coming to an end. Both the volume and the ferocity had certainly lessened considerably. Moving her wide eyes up to gaze into her father’s, Rainbow Dash began to pull her head away. Out slid Blaze’s wet cock, inch by inch, until the wide head popped free from her puckered lips. As they did his dick lurched violently again, firing another short, powerful jet of spunk all over his daughter’s face. His face began to grow red as he looked down at his little mare, spunk now strung over her muzzle and throughout her mane.

“Heh-heh, sorry my little filly. Didn’t realize there was any more to come… if, er, you’ll pardon the pun.”

Rolling her eyes, Dash stood, playfully flicking her dad across the nose with her tail.

“Don’t be making Dad jokes, you’ll ruin the atmosphere.”

She sidled up the bed, giggling to herself as errant semen dripped from between her lips. Resting her front hooves on Blaze’s shoulders she balanced herself upright, letting her Dad get a proper look at her belly. It was beautifully swollen, bouncing teasingly as Dash wobbled side to side. To a pony none the wiser, she could have easily been six months pregnant. Reaching out, Blaze began to run his hooves around her belly, sighing lustfully at the sweet feeling. His daughter was always stunning to him, but with her newly rotund belly he simply couldn’t hold back.

Dash gasped in surprise as she toppled backwards. Her father had delivered a light push to her belly with both hooves, leading her to fall flat on her back. Sinking down into the soft mattress and duvet, she smiled as her father loomed over her. Her eyes traveled downwards, drifting to his majestic cock again. It was still hard as ever, like he’d never even cum. His balls still looked deliciously fat, twitching occasionally - as if in anticipation. Biting her lip, Dash wrapped her back legs around Rainbow Blaze’s torso, before whispering up to him.

“I know what you’re waiting for Daddy, ‘cos I am as well… I need you in my asshole. Fill me up even more with your seed. If I’m able to lift myself up after this, well, you aren’t doing me right.”

Blaze smiled confidently. He and his daughter were always competitive, and she still had that little flare in her eyes, even during sex. He didn’t need to respond, his actions would speak for him.

Shifting around slightly, he felt his wide tip push between his daughter’s globular buttocks. He stayed there for a few moments, teasingly hot-dogging his daughter before the main event. All the while his cock occasionally spewed free yet more spunk, lubricating her little ass nicely. But enough was enough. Playtime was over.

Jerking his hips back, Blaze prodded his powerful cock against Rainbow Dash’s hole. She squeaked in excitement, her lusts rapidly bubbling over. She watched her Dad focus, settling into position.

“...Fuck me Daddy. Fuck me like I’m a filly again.”

Snapped back to those images again, Blaze instinctively surged forwards, burrowing his cock as deep into the needy slut as it could go. Now she was an adult, Dash’s body had unfortunately grown rather more accommodating to such big intrusions - shame, Blaze had enjoyed the sensations of having to try and work it in. Still, her euphoric screams of lust as he pushed in more than made up for it.

“CAN YOU TWO BE QUIET!? I’M TRYING TO READ!”

Oh, poor Firefly. She didn’t really have a space in these Father-Daughter games, so she just had to try and carry on with her day as normal. Try and ignore the fact her husband and their daughter were furiously making love in the other room - using sexual enhancements bought for her and her husband. Ignore the screams of ecstasy. Just keep reading the book.

Rainbow Blaze stood over his daughter, plowing into her ass. With every thrust her whole body rocked violently, as Blaze’s heavy balls smacked into her rump. She moaned through her lips as the rod filled her body, sweet desire rolling over her. The firm cock dragged across her warm innards, every pronounced vein and bump apparent to Rainbow Dash.

“Oh… I’ve missed this so much darling.” Blaze cooed through gritted teeth. Rainbow Dash tittered, opening her mouth to say something. However, the only sounds to escape her were a noisy moan as her father buried his length into her yet again.

His deeply probing cock had been spurting pre-cum quite continuously up until this point, lubricating her tight, dry hole with each moment. But then, just as sudden as the first, Blaze could feel an orgasm beginning. Slamming himself forwards again, he buried his length as deep as it possibly could be, his balls making a pleasant whap sound against her ass as he did.

Her belly immediately began to expand again, rapidly distending like a balloon filling with water. Her mouth - which had been lolling open - was suddenly snapped shut as Rainbow felt warm semen begin to push its way up her throat. Slow at first, it crept upwards, forced from her stomach but the endless stream of seed flowing from her father’s stallionhood. Blaze smiled, watching as his daughter’s cheeks began to rapidly puff out, spunk pouring into her mouth.

Any normal orgasm of Blaze’s would’ve trailed off by now. The intense tightness in his loins would fade, and the trail of cum would slow to a drip. Of course, this was not any normal orgasm. No, with thanks to Twilight Velvet’s magic potion, Rainbow Blaze’s balls were still churning out more and more seed. And yet, despite the ongoing orgasm, that telltale tightness had ceased. The feeling was odd, granted, but strangely wonderful. It now just felt similar to the sensation of urinating, just with a thicker, more viscous liquid pouring out. Was this supposed to happen, or was it a mistake in the magic potion? Or, perhaps, it was a bonus.

With the sensations of orgasm dwindling, Rainbow Blaze found himself taking a few slow, experimental thrusts. His daughter gurgled in shock, semen now pouring free from her mouth - she’d lost the ability to hold it all back a while ago. Then he found himself taking a few more.

And a few more.

Suddenly, he was ramming her again at full pelt, able to completely ignore the ongoing torrent of cum. It was as if he’d orgasmed, rested, and been able to go on to a second wind - except that first orgasm never ended. Grabbing hold of his daughter’s flanks, Blaze hoisted Rainbow Dash’s rear into the air, holding her akin to a wheelbarrow. His distended balls slapped loudly against the mares battered buttocks, a sticky squish sound emanating as they connected with the semen that had dripped free of her asshole. All the while Blaze watched his daughter’s face. Her wide eyed look of beauty had been replaced a gormless look of submission; the sheer force of these orgasms sending her mind spiraling. With each new powerful thrust, an additional wad of cum was forced free from her mouth and nostrils - clearly her body was reaching breaking point.

And it was certainly an impressive breaking point. Dash’s belly had expanded so much that by now her father could barely see her face behind it. Only the top of her eyes and her rainbow mane now poked out from underneath. But whether or not she was approaching breaking point, Blaze knew his orgasm was nowhere near ending. As he pulled backwards, ready to thrust again, more cum was drawn free of her asshole. It shot out, splattering across the bed and floor below.

Blaze - despite panting heavily - could make out his daughter beginning to moan again. It started out quiet, though grew steadily louder and louder, until it began reaching fever pitch. Her belly shook violently, and her whole body began to twitch in Blaze’s hooves. The bed below creaked and squeaked loudly, starting to struggle to hold the weight of the massively bloated mare.

Rainbow Dash yelled out euphorically.

Semen suddenly burst free from her navel, at such a ludicrously high pressure that the first spurt hit the ceiling. It clung there for a few seconds, before beginning to drip down onto the two like white rain. Then another burst from her navel, and another, and another. Growing longer and closer together, until eventually a solid fountain of spunk was flowing from her. Cum billowed free from almost every orifice now, painting the rainbow duvet a disgusting, sticky white. A great pool of the stuff had formed, dripping under furniture, and out under the door.

Now was the time for Rainbow Blaze to be starting to get worried. He hadn’t really considered before now, but perhaps he should’ve drank from that ‘growth potion’ a little more cautiously.

“F-Firefly’s gonna kill me for this!” He exclaimed, a look of real panic creeping across his face.

He was making a real mess of the furniture.

Rainbow burbled incoherently beneath an ocean of spunk, much of which had now soaked into her fur and mane. By now, there was little point calling her ‘Rainbow’. She was pretty much all white.

Slowly but surely, Rainbow Blaze could finally feel the ordeal coming to a close. His balls began to churn less and less, the river of high-pressure spunk slowing to a drizzle. He could also feel his cock beginning to rapidly grow flaccid inside his daughter’s rectum - surely now the potion had worn off. Unable to handle any more, Rainbow Blaze pulled backwards, his cock slipping free of her abused hole. The only barrier now removed, it was like watching a river burst its banks. Cum surged free like a jet-wash, coating Blaze in spunk where he sat. Too drained to move, he flopped backwards, letting the warm wave wash over him.

To neither ponies’ knowledge, the door slowly creaked open. Firefly looked in at the scene, both horrified, and mildly annoyed. After passing the heady stench of sex, she watched the spunk drip from the ceiling and walls, and stared over at the two unconscious ponies slathered in the stuff. There was no point trying to communicate with either of them till the morning - they were both simply too far gone. Instead, Firefly simply drew the door closed, before heading to the hallway and out the front door. She needed some fresh air. Plus, she wanted to pay a little visit to Twilight Velvet. Perhaps she would have some advice and spells to help reign in her horny husband...
