Silly Filly Spa

The four mares walked away from the pool, feeling practically weightless now that they were done with their pregnancies. Mostly. Each of the small colts has to trot quickly just to keep up with the mares' leisurely stride, obediently following close behind on a literal leash. They each looked at the umbilical cord still attached to their belly, and followed the length of it up beneath the tail of each mare, where their pussy lips were puckered around it hanging out of them, still connecting their fathers to the depths of their wombs.

Miss Harshwhinny led the group to the patio bar, where each of the mares climbed up onto the tall bar stools with the U-shaped seats, the gap letting their umbilical cord hang freely under them. Their fathers had to wait underneath the bar while their daughters were served drinks, there wasn't much else to do. Bow Hothoof's wings buzzed fruitlessly as he tried to fly up to reach his daughter's pussy, but his hooves never left the ground. Their marehoods remained out of their reach.

The mares finished their drinks in short time. Twilight felt a cool shiver run down her spine before it turned into a gentle warmth that settled into her lower belly. Looking at the others, it was clear that they were feeling the same way. A collective groan rose up from their fathers.

"It sounds like your graduation potion is working," Harshwhinny said. "As much as I know you wanted to 'reconnect' with your daughters, your literal connection isn't meant to last forever. The potion traveling through your cords will accelerate their growth after two more feedings." Aloe and Lotus stepped in to pick up each of the small stallions and placed them up on the bar in front of their daughters. "Ladies first. Your fathers' altered semen will catalyze the rest of the process."

Night Light sat in front of Twilight, waiting for his blowjob. But underneath his cord at his belly, his sheath didn't have so much as a bulge, despite feeling like he had blue balls.

"Give the coin purse a light flick," Harshwhinny suggested. They each did so making their fathers, and themselves, keel over like they had just gotten kicked in the stomach.

"Why!?" Firelight groaned, voicing what everypony was feeling.

"To elicit a sympathetic nervous response." Harshwhinny said. Everypony except Twilight looked at her. "Now you know how it feels for a stallion to be hit in the balls." She tried to hide her smirk. "Now give them a kiss to make it all better."

Diamond Tiara and the other mares leaned forward to kiss their fathers' scrotums. With her nose pressed up against his sheath, she found his scent to be quite inviting. Her kiss turned into a lick, and a suck. And just like that, she had both of his balls in her mouth as she swirled them around with her tongue. In a moment of clarity she realized what she was doing, and looked at the others, finding that they were each doing the same. In an instant, any shame she had vanished. The groans of pleasure from her father only spurred her on further. She looked up at him as his sheath bulged and his shaft sprouted quickly, laying upon her forehead until he hardened completely. Only then did she stop, to move on to more fruitful endeavors.

Without coaxing, provocation, or coaching, Diamond Tiara started to suck Rich's dick. The other mares were doing the same, but she didn't even look at them anymore. Her whole world was her father and his dick. He ran his hooves through her mane and moaned in pleasure.

"Oh fuck, Dia," Filthy grunted, "I can't even remember the last time your mother did this for me."

"Just to feel the touch of a mare," Firelight groaned, feeling Starlight licking his dick inside her mouth.

"I don't even care about Vel anymore," Night Light said, hugging Twilight's head as she sucked his dick.

Rainbow Dash bobbed her head like she was at a heavy metal concert. "Whoa, Windy never-" Bow Hothoof could only hold on as she sped up upon hearing her mother's name. "Dash, if you keep- I'm gonna-" Bow gasped breathlessly as she swallowed his entire length, pressing her nose against his belly. She could feel him twitching and jerking as he came straight down her throat.

Twilight's and Starlight's cheeks ballooned out with their fathers' cum before they swallowed.

Filthy Rich started to flare. "Diamond, I-" she dove forward, but he stopped her. "No, I want to see it in your mouth! Open wide!" She did as she was told and he held his dick against her tongue as he came. A pool of his cum filled the back of her mouth, but she held it there for him to see until he finished spurting. As soon as he did, she closed her mouth to swallow before proudly showing off her empty mouth.

"Yummy!" Diamond declared.

Twilight nodded in agreement.

Rainbow Dash burped. "Even the after-taste!"

Starlight rubbed her abdomen in discomfort. It wasn't the 'kicked' feeling from before. Just below her fading baby bump, she could feel her swollen teats filling with milk again.

"Ah, it looks like lunch will be ready soon," Miss Harshwhinny said.

"But we just ate," Starlight said, licking her lips.

Harshwhinny smiled. "I mean for the colts."

~

The set of hammocks in the bungalow quad made the perfect location for each of the mares to lay relaxed while their fathers could take their time nursing from their teats. Twilight looked at the size of Night Light laying between her legs as he suckled her nipples. She was scarcely able to believe that he was ever able to fit inside her. Quite in fact, while still quite small compared to her, he had nearly doubled in size since he had been born.

Starlight groaned as Firelight finished draining her teats. "Dad," she tried to push him away from sucking her sensitive nipples. "They're empty!"

One by one the other stallions finished. Bow Hothoof cozied up to sleep with his face pressed into Rainbow Dash's pubic fluff again.

"Eat and sleep. Eat and sleep," Harshwhinny said to the dozing ponies. "That's a newborn foal for you. Eat and sleep."

After a short afternoon nap, it seemed almost comically strange for Twilight to wake to her father draped over her legs as he was. He was almost as big as she was and yet he was still suckling milk from her refilled teats. The way he way laying let her hoof idly stroke his erection, making him moan as he drained her second teat.

Across from her, Miss Harshwhinny watched Firelight finish licking his daughter's milk from his lips. Once everypony was awake and finished nursing, she guided them to follow her into the resort courtyard. The mares led the way and as before, their fathers followed closely behind them.

Aloe and Lotus placed four pads in the middle of the grass. Harshwhinny directed the four stallions to lay down on their backs with their heads towards the center of the cross. She waved for the mares to join them and take their seats. Bow looked up eagerly as Rainbow Dash squatted over his face. The umbilical cord dangled out of her pussy and he held it out of the way as she kneeled down to sit on his face. The stallions needed no instructions as each one eagerly licked his daughter's pussy.

The four mares were sitting in a tight circle, close enough for their knees to touch the others on either side. They looked back and forth and across at one another, but mostly they each looked down at their father's head between their thighs.

"How have we been enjoying our stay so far?" Harshwhinny asked the group.

The question took a moment to register to the mares amid their tongue-lashing. "The food's good," Diamond Tiara said without really thinking.

Harshwhinny looked at Filthy Rich's bobbing erection. "Hmm, I'm sure your father would agree with you on that."

"F-fuck, Dad!" Rainbow Dash moaned. "And I thought AJ was good at this..!"

"Usually I'm the one doing this for Trixie," Starlight said. "It's nice to be on the receiving end once in a while," she moaned.

"I actually have some notes," Twilight said. Night stopped what he was doing. "No, not for you, Daddy. You're doing amazing!" Night Light happily resumed. "I wasn't a fan of being tricked when we got here. I certainly didn't think I'd get a massage where my shrunken father would get spurted into my uterus, and I'd have to go through a rapid pregnancy this week!"

"It was all plainly outlined in the forms you signed when you arrived," Harshwhinny said.

"Dammit. I really should have read that!" Twilight grumbled. But her sour mood wouldn't last long. Night Light's umbilical cord obstructed Twilight's vagina, but that didn't stop his tongue from trying to join it inside, as well as give the rest of her pussy lots of attention.

Starlight and Diamond Tiara shuddered almost in unison as they both orgasmed. Twilight wasn't far behind. Her hoof grabbed Night Light's horn to keep herself from nearly keeling over. Even so, her other hoof had to steady herself on the grass in front of her.

Rainbow Dash's entire body practically vibrated and her hips rolled against Bow Hothoof's face until she cried out and arched her back as she came. He did his best to cup her pussy with his mouth, but Twilight found herself in the splash zone. Harshwhinny tried not to laugh as Lotus brought Twilight a towel.

A couple of the other spa staff placed a small table in the middle of the group and placed dining settings, followed by a served dinner.

"Um, what about..?" Twilight pointed at the stallion she was still sitting on.

"They will still get their nutrients through the cord, and your milk," Harshwhinny explained.

"Aren't you uncomfortable?" Twilight asked Night Light. She tried to stand but his hooves grabbed her hips and held her firmly to stay sitting on his face.

Harshwhinny smiled. "He seems fine to me. Enjoy your dinner ladies."

Dinner was a quiet affair, aside from the occasional clink of silverware, and the mares chewing their food. And of course the ever-present sound of their fathers slurping their pussies.

The water in Starlight's glass shook and spilled in her trembling hoof. Her other hoof was holding onto the edge of the table as she came again.

Rainbow Dash nearly choked as she tried to chew. "And I thought AJ has a lot of endurance..."

"Making up for lost time, no doubt." Harshwhinny said, looking over at Diamond Tiara's eyes glazing out of focus. "I'm sure there hasn't been a day gone by since your first heat that he hasn't wanted you to sit on his face like this."

Once everypony finished eating, whether it was hors d'oeuvres, pasta, poutine, or horse pussy, they were all ready for a good night's sleep. The night was warm, and sleeping under the stars in the quad's hammock appealed to all of them.

Princess Twilight Sparkle sat proudly on her throne. In her hooves laid her beautiful foal, little Night Light. "He looks just like his father," Twilight mused. The doors to the throne room burst open. The evil King Sombra charged inside. Twilight tried to use her magic to stop him, but nothing happened. He snatched away her foal. She reached out to save him, but Sombra swung his sword, severing her hooves from her legs.

Twilight lurched awake with a start, feeling the sharp pain that only amputees knew when losing a part of themselves. Her eyes looked over herself frantically, finding Night Light laying on top of her in the hammock. She hugged him closely. As she did she could feel the severed umbilical cord slip out of her vagina, and then falling free from his belly before shriveling up.

Next to her, Starlight awoke with a similar start. Rainbow Dash just held her father tightly, rocking in the hammock as she quietly sobbed. Diamond Tiara tried in vain to put the cord back inside her marehood like a limp noodle. "Daddy, fix it!" she cried.

"I'm sorry," Filthy said, feeling the cord separating from his body.

"Ladies, ladies!" Harshwhinny addressed them as she quickly trotted over to the noise. "What you are experiencing is just a fast, hard-hitting case of post-partum depression. I promise that if you just remain calm, it will soon pass."

"Back inside! Back inside!" Starlight cried, pressing her crotch against Firelight's body.

"Would if I could, Pumpky Wumpkin," he said with tears in his eyes, knowing damn well that his body was far too large now to ever fit back inside her. She held his head against her chest. Her only comfort was feeling his sheath nestled against her marehood.

True to Harshwhinny's words, severe though it was, the feeling did soon pass. "The final day is always a rough start," she said. "But now we can complete the program. Gentlecolts, now that you are back to full size, you ought to know how hard it was carrying around another pony inside you."

"Do not put me up his ass!" Twilight said.

Harshwhinny laughed so hard she snorted. "No no! Nothing so invasive. Just some friendly competition between the stallions."

Aloe and Lotus fitted each of the stallions with a specialized harness, and then did the same for each of the mares to be carried.

"I mean, technically..." Twilight Sparkle tried to say as the straps of her sling were tightened, lifting her up to press her belly against her father's belly with her legs on either side of his body. She craned her neck to look at the world upside down between his front legs. The other mares were similarly strapped in.

"So what kind of competition..?" Rainbow Dash asked.

"Oh, just a light run down the beach," Harshwhinny said. "To see who comes in first."

The stallions wasted no time, trotting towards the water. Despite the awkward position, the mares were quite comfortable riding along in the slings. The clopping of hooves on stone became muted pats in the soft sand as the trotted along the edge of the water.

Diamond Tiara was enjoying the ride when she felt her father's sheath start to bulge against her marehood. His erection started to sprout and there was no place for it to go but with his tip pressed against her pussy. With her legs already spread it wouldn't take much more. Her squirming only helped her pussy to get the tip lubricated and make him get harder. After just a bit more pressure, she felt his tip pop inside her. "Um, Dad!?"

"I know sweetie, but it can't be helped," he said as he trotted to keep up with the other stallions. It took all his concentration to just keep his legs under him as his shaft swelled to full mast, pushing itself deeper inside his daughter. Diamond grunted as he stumbled a little in the sand and she felt his dick lightly bump into her cervix. She tried to adjust herself in her sling but found that she was quite immobile. "Sweetie, please stop squirming. You're only making it harder."

"I can feel that," she panted.

The stallions reached the end of the beach and turned around for the return leg of the race. Diamond Tiara looked next to her at Starlight Glimmer, laying in the sling under her father with her tongue lolling out. Ahead of her, she could only see Bow Hothoof's backside. Under his balls, she could plainly see he was similarly hilted inside of Rainbow Dash's dripping pussy.

"F-fuck, Diamond... I don't know if I can make it. Have you been taking your Moon Tea?"

"What? No! I didn't think I'd be doing that this week!"

"Shit..." He grit his teeth and focused on not cumming inside her.

Miss Harshwhinny galloped down to the beach from the resort. "Ladies and gentlecolt, I'm afraid we're going to have to cut this activity short! The resort is getting a surprise inspection." She quickly went around and released the harnesses, separating the ponies.

As Diamond Tiara was lowered to the sand, her father's shaft slid out of her pussy and sprang up against his belly with a wet slap. As she suspected, the same thing happened to the other pairs.

"Gentlecolts, into the cold ocean!" Harshwhinny directed. "Get those erections put away quickly!"

"What's going on?" Twilight asked.

"Princess Celestia is on her way here for a surprise inspection," Harshwhinny said.

"Isn't everything you do here above board?" Twilight asked.

"Everything we do." Harshwhinny said. "But do you really want her to catch you engaging in incest?"

The fog clouding Twilight's rational thinking lifted for a moment, and she realized that not everypony would be okay with what she was doing with her father.

"During the inspection, we can still do normal resort activities," Harshwhinny said as they walked back from the beach.

Celestia arrived at the foyer at the same time as the group. "Ah, Twilight! It's good to see you!"

"Hi," Twilight greeted nervously.

Diamond Tiara bowed nervously.

Celestia waved her off. "There is no need for formalities. Just pretend I'm not even here."

"Everypony," Harshwhinny guided, "This way to the orchard. For our next resort activity, we are about to pick some lemons. To make fresh lemonade." Aloe and Lotus scrambled to grab some step ladders to bring out to the resident lemon trees. Gentlecolts, if you wouldn't mind picking your choice of fruit from the trees. And ladies, you can help by holding the baskets."

Celestia waited off to the side and watched.

The task would have been easy for Bow Hothoof to just fly up and gather the best lemons with ease. Twice as fast with Rainbow doing the same. After both being so close to cumming during the jog, they were both too horny and nervous to fly. It took all of Rainbow's concentration to restrain her wingboner, and for Bow to restrain his regular one.

Twilight thought she knew how to handle the stress of pressure. But never before had Celestia's watchful gaze felt more heavy upon her. Night Light climbed the ladder to reach the fruit among the tree branches.

Starlight Glimmer had only just recently learned how to manage her feelings of guilt. But not it was boiling back to the surface. Firelight grabbed a couple and reached down to put them in her basket.

"Twilight," Night Light said, getting her attention. He passed her a couple more lemons. He could see the sweat running down her tense face. She bit her lip anxiously. "I know, Twilight," he whispered. "I know."

He did, didn't he? Twilight thought. This feeling she was experiencing, this shameful mixture of taboo desire and fear... this carnal urge that he had been feeling ever since she became a mare, that had to control and repress for years. All because of a society that didn't understand how he felt. How he still feels. And how she feels.

Diamond Tiara looked at the pair of lemons in her hoof. The shape and weight of them. It was evoking a very specific imagery in her lust addled mind. She placed them in her basket and reached up to get the next ones. Filthy Rich flinched as he felt his daughter cupping his balls. He stifled his reaction to avoid attracting attention. Fortunately, Celestia was watching Twilight at the moment. Diamond Tiara was oblivious to the world around her, drooling as she gently held her father's balls in her hoof.

Starlight gravitated closer to her father on the ladder until she was nuzzling his coin purse with her cheek.

Rainbow Dash was less subtle, pressing her snout right up against her father's sack, breathing in his stallion musk. Her wingboner stood stiff on her back.

Twilight shuffled her hooves anxiously. She could feel her wetness between her thighs. So tantalizingly close. But she could feel Celestia's eyes on her. It was agonizing. All this time all he wanted was for her to sit on his face to please her. And he was denied that. She was denied that. It wasn't fair.

Her eyes were half-lidded as she remembered that feeling of his tongue on her marehood. She licked her lips, pantomiming the memory for herself. Without thinking, she gently licked and sucked her father's balls, making his erection sprout out from under him.

"What is the meaning of this!?" Celestia shouted. Twilight and the other mares all snapped out of their daze and looked at Celestia. "Night Light! Do you have an erection for your daughter!?" she shouted. Night Light stood frozen on the ladder. There was no way for him to deny having an erection. It stood hard as steel under him as plain as day.

"It's okay!" Twilight said. "It's perfectly natural."

"Of course it's natural," Celestia said. "All fathers lust after their daughters. But most have the common decency to repress those emotions by taking out on their own body with alcohol until they give themselves a heart attack! As for the rest..." she looked at the other stallions' erections, "That's why we have gelding clinics! Which is where you stallions will all be going! But as for you, Night Light, I shall see to it personally!" Celestia's magic brandished a set of gardening sheers.

"No!" Twilight screamed, putting herself between them. "If you even try it I- I'll..!" Her horn crackled weakly with her magic still yet recovering. Her hoof grabbed a fallen tree branch like a club. "You'll have to kill me first!"

The other mares also took a protective stance in front of their fathers.

"Easy there Twilight!" Night Light said. "Stand down!"

"Ocellus, that's enough!" Harshwhinny shouted. Celestia quickly transformed into a changeling. Ocellus tossed away the garden sheers and took several steps back.

The stallions climbed down off the ladders to hug their daughters.

"What the hay is going on!?" Rainbow Dash asked.

"My apologies, ladies," Harshwhinny said. "But this was designed to teach you how it feels to be a father. All the feelings of fear, anxiety and repressed shame. But also, for you to understand the selfless feeling of protectiveness of that which is so precious to them."

Precious. That was the word on Twilight's mind. She never really understood the term 'family jewels' as a euphemism for referring to a stallion's testicles. But now the meaning was only too clear. They were what made family. Her and her brother. Without her father's testicles, she would not exist. Mothers get all the credit, and while most of that is well-deserved, it ought not be at the expense of the father's contribution. And his jewels. They were... precious to her.

Twilight hugger her father back. "I'll never let anything bad happen to your jewels!" she cried. The other mares expressed similar sentiments. Twilight rolled Night onto his back in the grass and climbed into his lap to finish what they had started earlier. "I'll be so much better than Mom!" she said as she squatted and lowered her hips onto his cock. She moaned as it slid inside her. "I'll empty your balls every day!" The other mares started doing the same thing with their fathers.

Twilight had a brief moment of self-awareness and looked at Ocellus. "Wait... you're not going to tell anypony about this, are you?" she asked.

Ocellus shook her head. "I already signed an Non-Disclosure Agreement. And besides, I'm a changeling. We have no concept of incest. Our whole hive all came from one queen mother. All the grubs being hatched now? They're all from my brothers and sisters. These sexual hang-ups that your pony society has are fucking weird."
