“Now come give daddy some lovin’,” he ordered. Without missing a beat, Steel Metal pounced on his cock, lathering his balls with her saliva and inhaling his musk, which she loved the smell of.

“Mmm, that's daddy’s girl," he moaned, smiling and affectionately petting her head. As his dick grew, it flopped over onto her head, growing up the top of he muzzle until it was mostly extended, at which point it began hardening, becoming almost parallel with his stomach.

“Time to move on to the shaft, sweetie," he told her. She gave his balls one final kiss before continuing, making sure to reach around his cock entirely and cover it in her spit as she slowly worked her way up.

Soon, she reached almost all the way to the tip, but was too short to reach the whole way. Instead, she began lapping at his cock, hooking a hoof around it and stroking it as her other hoof fondled his balls.

“Nngh, d-daddy's getting close, so daddy's gonna pick you up and rut your throat, okay?” He told Steel, before grabbing her sides and flipping her upside down and around so her belly was facing him, before slamming her down on his cock with a grunt, before hilting in her throat about half way down his dick, and hugging her close, feeling the indent of his massive horsecock in her tiny throat on his belly, before beginning to yank her up and slam her down as he thrusted up as fast as he could.

Quickly, he was pushed over the edge, and let out a loud moan of pleasure as he slammed her down, pushing past into her stomach and fitting three quarters inside her before his balls began tightening, launching rope after rope of his thick and creamy seed straight into her belly. It quickly filled her to the brim, and he could feel her belly begin the press against his as his cum began to spurt out around his cock, splattering his crotch and her muzzle with his juices.

After a few more moments, he finally hit empty, panting as he pulled her up and off of him, revealing a still rock hard cock, painted white.

She was limp and unmoving at first, making him panic in fear that he'd pushed too hard, but she quickly started gulping down air and coughing.

“My Celestia, are you okay dear?" He worriedly asked, hugging her close. It took her just over a minute to respond.

“I'm fine,” she responded. “Can we do my vagina now?” He chuckled, looking down at her vagina right below his nose.

“Of course, honey," he said, then began lapping at her sex. She moaned, then let out a sharp gasp, her rear jerking and pussy winking wildly. He chuckled into her taint, making her gasp again.

“Close, are we?” Her dad asked.

“Yes daddy!" She exclaimed. “Make me cum with your tongue, daddy!"

“Gladly," he responded, then placed his lips around her rosebud as she winked, making her gasp, whimper, and moan, wiggling in his grasp as he sucked on her clit as if his life depended on it.

“D-d-daddy!” She screamed, and he let go of her sensitive flesh and stuck his tongue as deep as he could in her love tunnel and licking all her sweet spots, pushing her over the edge with a loud and whorish moan as she came hard, bucking in his grasp as she blasted fillycum all over his face for nearly half a minute.

After noticing the lack of her juices hitting his muzzle, he pulled his tongue out and continued lightly licking her slit and around it, cleaning her crotch of her juices.

“Did you go number two today at school, honey?" He asked.

“Nuh-uh,” she replied, barely able to think as she panted heavily beneath him.

With that information, he dragged his tongue over her tailhole, making her gasp.

“Daddy?" she questioned.

“Just preparing you for the next part, honey," he grumbled, before wrapping his lips around her ponut and suckling it as he stuck his tongue as deep as he could into her ass for only a moment, making her gasp again before he quickly pulled back.

“T-That felt good, daddy," Steel told him.

“Did it?" he asked before spitting a glob of saliva onto her tailhole, rubbing it around with his muzzle. “Then this will feel amazing.”

“What are you gonna do, daddy?" she asked.

“We're gonna do butt stuff,” he answered, flipping and turning her again so he could see her extremely excited expression and huge grin, holding her in front of his cock.

“Really?! We never do butt stuff!” She excitedly exclaimed.

“Yes honey,” he said, kissing Steel on the lips. “Butt stuff.” He lifted her up, carefully placing her tailhole on his tip. “Now get ready!"

“I'm re-ahh!” she gasped mid sentence as her dad pushed her down.

“Damn, your hole’s gotten harder to get into," he complained.

“Of course, daddy! We haven't done butt stuff in ages!” She reminded him.

“And I won't let that happen again," he promised. “If only-” thrust “-I could-” thrust “-get-” thrust “-in!” He winced as his cock finally entered her ass, making her Yelp in pain as she quickly and suddenly sunk all the way down to his medial ring, before she bounced, popping it into her.

“Look daddy!" she exclaimed. “I can finally reach your medial ring!"

He chuckled. “Good job, honey." He pecked the top on her head. “Now, are you ready?"

“I've been ready!" She happily answered. “Fuck my anus raw, daddy!"

“Who taught you that language?!" He snapped, making her flinch.

“D-Dinky,” she told him. He sighed.

“I'm gonna have to have a talk with that filly's parents," he told her, wincing as he instinctually thrusted, hugging her close and resting his head on top of hers.

“Looks like my penis can't wait,” he told her, repressing another thrust into a small push. “Get ready sweetheart!”

He began thrusting, struggling to maintain a steady pace as she bounced in his lap.

“J-just tell me if you want it faster, baby," he told her.

“Give me your all, daddy!" She exclaimed barely see moment later, and he immediately let loose, releasing a long and loud moan as he rapidly fucked her and bear hugged her.

“Oh, my little baby!" He exclaimed, his thrust containing absolutely no rhythm as he wantonly rutted her, groaning and whimpering into her ear. “My little baby, I'm so close! G-get ready, baby, i-i’m gonna fill you! I'm gonna fill you up with my seed, baby!” He rambled on.

Within a few moments, he shoved her down and held her, stuffing as much of his cock as he could in her ass and hugging her tightly as his throbbing shaft ejected massive loads of his creamy spunk, bucking up every so often with a whimper.

“I love you so much, Steel, I love you so very much, and I'll never let you go,” he started, panting as he continued pumping her full, despite the seed starting to spurt out from around his cock. “You're the best in the whole wide world, even better than Celestia, and I love you Steel.”

“Dad?"

“I'll hold you forever and ever, and always keep you safe…"

“Dad."

“You'll never get hurt ever, you'll be safe forever baby, safe forever…"

“Dad!"

“Huh?" his eyes opened, looking around the room as if he were lost as he breathed heavily.

“What was that, dad?" Steel asked, nuzzling her father.

“W-What was what, honey?" He asked with red cheeks and a nervous grin, rubbing her back with a hoof.

“You were saying so many nice things about me, daddy," Steel explained. He sighed in relief.

“When I feel really, really good, I blurt things out,” he explained. “I'm glad you stopped me before the good thought ran out.”

“You're welcome!" Steel chirped. “Now what's next?"

“H-how old are you again, honey?" He asked.

“Nine. Why?" She questioned.

“That just means I can still give you a good ol’ creampie," he explained.

“Why can't you give me creampies forever?" Steel inquired.

“Because at a certain age, fillies like you hit puberty and start becoming fertile, and I don't wanna put a baby into my daughter," he explained.

“How come?"

“Because… Ugh, can we move on before we run out of time?" He asked.

“Okay daddy!" Steel replied.

Her father placed one hoof and lowered himself to the floor with a groan of exertion, carefully laying Steel on the floor before putting both hooves on the ground and straightening his forelegs, then began slowly pulling his penis out until his cock slipped out, letting cum drip out and pile beneath her.

With a shaky hoof, he guided his penis, rubbing the tip against her snatch. He weakly thrusted a few times with shivering hips.

“Daddy, you can barely stand. Let me handle this," Steel told him, placing a hoof on his chest.

“You sure, honey?" He questioned, making eye contact with her.

“Yes. Now lay on your stomach."

“Wha-my stomach?” He asked, doing a double take. “Why my stomach?”

“Dinky told me that mares can make stallions feel good by licking their tailhole, so I wanted to try it.”

“You wanna give me a rimjob?" He asked.

“Pleeeeease?” She asked, giving him puppy eyes.

His heart melted as he sighed with a soft smile. “How could I say no to that face?"

“Yay!" She exclaimed. She closed her eyes and pickered her lips, requesting a kiss. He planted his lips against her for a full second before pulling them off with a wet smack. He stood fully, still shaking in his horseshoes, and slowly backed up, before doing a one-eighty and slowly lowering himself to the ground with a groan of exertion.

“Don't look back! It makes it harder to do my stuff," Steel told him.

“Sure honey," he mumbled, resting his head on the ground as he struggled to keep his eyelids half open.

“Actually, go ahead and take a nap. We can finish later," Steel told him, snuggling into his side.

“But I'm supposed to be pleasing you…" he whined quietly as his ears splayed back, his eyelids already closing.

“I can wait,” she whispered into his ear.

“But…" he started at a barely audible volume, before his eyes closed fully, and he started to quietly snore.

“Sweet dreams, daddy," Steel muttered, before quietly standing with a plan in mind.

“Huh? Baby?" Steel’s father yawned, eyes fluttering open. He felt a strange warm feeling in his anus, before hearing a masculine sounding moan from behind him.

“Steel?" He tiredly asked, slowly moving his head to look behind him. What he saw was not what he expected.

“Steel Metal?" He asked, blinking multiple times as he stared at the colt with the exact same colors as his filly. The colt was looking back with a nervous smile as he was mounted on the stallion, one small hoof pinning the fathers tail to his back as the other held a softening horsecock.

“Did you…" The stallion trailed off, trying to comprehend the scene.

“I know this looks bad, but I can explain!" The colt hurriedly said.

“Who are…" The stallion started, his brain starting to reactivate.

“D-d-don’t worry! I'm your Steel Metal, through and through! Dinky just lent me a magical pill that transformed me into a colt for a few hours!” The colt tried to explain.

“Prove it."

“I-uh,uh look!" The colt said, turning around and flipping his tail over his back, presenting his backdoor, leaking with cum.

“Remember when we did butt stuff? You said you felt really good, a-and that's why you were saying so many nice things about- oof!" The colt was interrupted as the stallion knocked him to the side and onto his back.

“Daddy?! What are you- whoah my Celestia, that's good!” The colt exclaimed as the stallion wrapped his lips around the colt’s cock that was surprisingly stallion sized for his age and began deepthroating the everliving buck out of it, making loud slurping noises a he went up and down really fast, turned his head from side to side, fondling the little one’s balls with a hoof.

“Ah! Hah! Ooh! How are you- nyah! So good at this, daddy?!” The colt got out between grunts, jerking into his father’s mouth as waves of extreme pleasure crashed through his little body.

“Ah! AH! L-let- unh! Let me c-cover your face, daddy!" Steel shouted. His father sucked up his entire cock and held it in his mouth for a moment before pulling it out completely with a pop, moving back and angling it towards him as he hooked his other hoof around it and rapidly pumped up and down. His muzzle was wide open, his tongue dangled out, and his eyes were shut.

“Ah! Wow! DADDY!" Steel’s cock erupted, blasting his father’s face, who flinched at the first rope from his daughter-turned-son’s monster cock, which landed across the stallion's forehead, making his hoof slow down considerably so the colt's seed didn't go everywhere.

Some of the spurts covered his muzzle, forehead, mane, and one even got on his closed eye, with some luckily making their way into his mouth, which he dare not swallow until his Steel Metal commanded it, although he did open his eyes a crack after noticing there was no more delicious cum to look at his son.

“Oh Celestia, daddy, you look so hot,” Steel told the stallion, blushing a deep red. “Is that what I look like when you cum on my face?"

Without a word, his father nodded. Steel bit his hoof, watching his father pant like a bitch in heat. Steel stopped biting his hoof and moved it to pet his fathers head instead, who closed his eyes once again and leaned into the touch.

“I need to ask Dinky for a necklace with that spell,” Steel muttered.

They stayed like this for a minute.

“Uh, dad?" Steel asked. “You look a little pent up. Wanna release that into my pussy?"

Her father moaned, opening his eyes. He swallowed his daughter-turned-son-turned-daughter’s cum before speaking.

“Of course, baby," he replied. At some point, he had raised his ass into the air, and his erection hung there, throbbing painfully. He stood fully, lowering his rear and holding his cock down with a hoof so they were level with her taint, and waddled forward until his tip pressed against her pussy.

“Are you finally ready for the main event, my amazing little baby?” He asked, grinding his glans against her winking fillyhood.

“Just go in already!" Steel exclaimed. Quickly, he placed a hoof to her chest to hold her in place, with the other pulled up to his chest, his center of weight carefully balanced so that he wasn't crushing his only filly, and popped his tip into her wet cunny with a groan. He pushed it in before his medial ring stopped him, then he thrusted, surprisingly fitting the rest inside, grunting as his crotch slapped against her small asscheeks.

“That's new," he mumbled, cracking an eye open to make sure she was okay. Considering her ahegao, he assumed she was fine and closed his eye again, pulling out before beginning a steady rut.

“Does that feel good, s-ugh, baby?" He asked, resisting the urge to dirty talk as he also resisted the urge to speed up, wanting to give his daughter’s womb the cum it so desperately wanted.

“Yes! Fuck your little slut, daddy!" Steel screamed.

He whimpered, but his instincts made him accelerate exponentially.

“Yes! YES! MAKE ME YOUR LITTLE SLUT, DADDY!"

Despite heating those words from his daughter, his cock still loved the funny words from the magic filly. With a loud moan, he hilted inside her, his hips bucking with each load sent into his daughter’s young womb, easily filling it and forcing most of his loads to spurt out onto their crotches, painting them white.

“I love you so fucking much, baby…"
