Silly Filly Spa

Diamond Tiara slowly waddled from her bungalow to the resort pool, struggling to walk with her very pregnant belly swinging under her, along with her pendulous teats, swollen full with precious milk for her coming foal. She un-gracefully fell into the pool water and groaned as she floated there. "I'm starting to really re-think this whole, having foals thing."

The other mares floating in the water groaned in agreement. Laying on a mattress or a padded cot no longer was enough. The buoyancy of the water was the only reprieve for the strain on their bodies from carrying their growing fathers around inside their womb.

Miss Harshwhinny stood at the edge of the pool. "Good morning ladies. You'll be pleased to know that this is the final day that you'll have to endure your expedited pregnancy. Gentlecolts, I'm afraid today I have to issue your eviction notice."

The stallions groaned from inside their daughters' stretched wombs. Firelight's knees were pressed right up against his chin. He was curled into the literal fetal position, with no space left at all to move or grow inside his daughter's abdomen. Even so, "I don't want to go!" he complained. "This has been the most relaxing vacation I've ever had in my life!"

Murmurs of agreement rumbled from the other mares' bellies.

"I'm afraid this is not up for debate," Harshwhinny said. "It's time for you to get out."

Twilight Sparkle looked nervous. "My mom told me about this part. The bungie harness and the dildo jackhammer to pop through her cervix." All the other mares winced.

Miss Harshwhinny nodded. "We've come a long way since then. We've made major strides. No harness, no jackhammer. Just a natural, potion-induced, birth."

Aloe and Lotus each walked over with a tray. One with a set of drinks, and the other with the set of custom dildos.

Twilight waded over to the pool bar.

Night Light's frantic voice rambled from her belly. "Twilight, listen, we can just tell your mother that I'm staying with you for a while. She doesn't have to know that I'm staying in you."

Twilight picked up an induction potion bottle from the tray. "Sorry, Dad. But I have a nation to run." She drank the potion. Aloe and Lotus helped her to climb up out of the water onto the smooth ledge.

Harshwhinny connected Night Light's dildo to the pump tube. "Donated changeling secretion," she explained. "Back when they operated as parasites, it was used to make a mare's cervix numb and stretchy for their ovipositor to lay eggs inside."

"Well that's... horrifying," Starlight said.

"And fortunately it is a thing of the past," Harshwhinny said. "On the plus side, this'll make it easier for you to push your fathers out."

Twilight spread her legs and Harshwhinny pushed the dildo inside, pressing the tip squarely against her cervix with the perfect fit of Night Light's dick for his daughter's vagina. Harshwhinny turned on the pump and the changeling secretion flowed up the tube through the dildo. Perfectly aligned with the entrance to her cervix, it pumped straight inside her uterus. Though he didn't need to breathe, Night Light held his breath as it filled what little space was left around him. Once the secretion started spurting out of Twilight's pussy, Harshwhinny knew she was filled. She pulled it out and waved for her to roll back into the water.

Starlight paddled over as Twilight waded into the shallow water.

"Starlight, sweetie, I'm not asking to stay in here forever. Maybe just for the summer before you have to go back to work. You could just tell Trixie-"

"Save it, Dad," she wheezed as she tried to climb out of the pool. Proud as she was, Aloe and Lotus helped her to climb up out of the water. She drank her potion and Harshwhinny pumped her full of changeling secretion before rolling her back into the water.

"I guess this means it's time for you to kick me out too, huh?" Filthy Rich asked Diamond Tiara.

"Well, I was thinking," she said as she paddled over to the edge of the pool. "Since you could stay in there indefinitely, and I'm next in line for your life insurance inheritance... maybe I could just..." She struggled to climb out of the pool. Aloe and Lotus helped her to climb up out of the water. She got to her hooves. "Maybe I will just keep you in there and..." she panted after a few steps before laying back down to get off of her swollen hooves. "Okay, no, not worth it! Get him out of me!" She drank the potion and rolled onto her back. Her the outline of father's erection was visible inside her belly. She spread her legs and Harshwhinny pumped her womb full of changeling secretion. As it spurted out around the dildo out of Diamond's stretched vagina, Harshwhinny turned off the pump and pulled it out.

Rainbow Dash quickly paddled over next.

"Dashie, wait! This has been so nice reconnecting with you! I know you're the fastest pony in Equestria, but we don't need to rush the ending of this!"

"Dad, I'm not the fastest anything with you inside me. I can't even fly anymore, let alone get back into a Wonderbolt uniform! And AJ is never gonna let me sit on her face again if I weight twice as much!" Aloe and Lotus helped her to climb up out of the water. She drank her induction potion as Harshwhinny connected Bow's dildo to the pump.

Inside her womb, Bow could feel the cool changeling secretion pumping in through her cervix. With his knees up to his cheeks, Bow Hothoof had barely enough room inside his daughter's womb to even move. His erection poked his snout. "Shit, gotta go fast for one more!" He quickly started to suck his own dick.

Rainbow Dash moaned as she squirted marecum in Harshwhinny's surprised face. "Sorry!" Dash apologized.

"It's quite alright." Undeterred, Harshwhinny held fast, keeping the dildo pressed firmly inside Dash against her cervix until she was filled to the brim. She wiped her face dry with a towel and the pregnant mare rolled back into the water and wadded over into the shallow end with the others.

Twilight Sparkle propped herself up on her elbows in the shallow water. Her knees and the top of her massive belly the only other parts of her not submerged. She looked at the empty potion bottle on the tray. "So how long before- HNNG!" Twilight doubled over in the water and groaned as the first contraction started.

Inside her womb, Night Light felt his daughter's muscles squeezing him from all sides with his head against her cervix, pushing his horn through the small opening. Twilight panted rapidly. Even though she knew what to expect, nothing could ever really prepare her for this. But generations of instinct took over and her body know what to do. She grunted and pushed as the next contraction hit. Her cervix stretched as Night Light's head was pushed through into his daughter's birth canal.

Rainbow Dash cringed as she watched her friend go into labor. "Wow, that looks like it suUUGHH OH FUCK!" she cried out as her contractions started. She grabbed her belly with her hooves. "OH!"

Starlight looked back and forth between them. "This would really be a lot easier if I could use my magic to teleport them ouOw OW!"

Diamond Tiara looked at her belly nervously. "Dad, I'm scared!"

"Don't worry sweetie, you're gonna do great!"

"You said you would never do anything to hurt me! That look like it hurts a lot! Make it not hurt!"

"I can't do anything in here, sweetie. This is on you. You can do it."

Diamond looked at Harshwinny. "Is it too late to take an anti-do-Oh OH!" she groaned and squeezed her belly. Her next contraction pushed Rich's head against her cervix, stretching it wider. "Daddy! You feel huge!"

"Phasing!" Rainbow Dash managed to get out between her labored breathing. "Boom!" Her next contraction knocked the bravado out of her. The coordinated muscles of the athletic mare pushed Bow's head against her cervix. And as much as he wanted to stay, he pushed his legs against the top of her uterus to help. Her strained groaning thundered all around him as she pushed his head through into her tight vagina.

Inside Twilight Sparkle, Night Light felt like he was being crushed on all sides by the weight of the ocean. Then he felt the sharp sensation of the comparatively cool pool water on his horn.

Aloe and Lotus carefully waded into the shallow water with the foaling mares. "Ooh, it looks like somepony is crowning!"

Rainbow Dash yelled out a mighty battle cry with her next push, and a flash of rainbow mane appeared between her legs. The spa twins scrambled through the shallow water as her next push got her father's head completely out. His shoulders and the rest of his body followed quickly after. Aloe and Lotus helped him into Rainbow's waiting hooves.

Miss Harshwhinny looked at her watch. Despite being the last one to take the potion, Rainbow Dash was the first to finish foaling. "That's got to be a record!"

The twins helped Rainbow up onto one of the pool floats. Bow nestled himself between his daughter's legs to start suckling from her swollen teats, heavy with nourishing milk. Proportionately, he didn't look like a foal. He looked like a shrunk-down stallion.

Meanwhile, Twilight Sparkle huffed, and puffed, and pushed. Night Light shifted a couple more inches, stretching Twilight's marehood to it's limit around his head. Night Light's eyes winced against the bright sunlight refracting through the pool water. Blurry shapes of pink and blue hovered over him as Aloe and Lotus watched her progress. They helped support his head and small body as he was pushed out. As soon as she finished foaling, he tried instinctively to paddle, but his small limbs quickly tired. Aloe and Lotus helped him into Twilight's hooves.

Starlight Glimmer wasn't far behind with her progress. Just as Aloe and Lotus finished getting Twilight up onto her pool float, Starlight had gotten most of Firelight's head out. Lotus grabbed another float while Aloe helped Starlight finish. Firelight felt himself being pushed out of his daughter's comfortable warmth. His world spin around leaving him dizzy and disoriented as he was lifted up out of the water.

Starlight's hooves sat him between her legs on the pool float. Her massive teats waited before him. He looked down at his umbilical cord connected to his belly he followed it between her legs into her vagina. She gasped as he pushed his hooves back inside her, spreading her open. His legs could get to traction to push himself back inside, and he could do nothing but watch her cervix seal closed around the cord. "No, no!" he cried. The way was shut. There was no going back inside. Lotus pulled him away to get his hooves out, letting her pelvic muscles relax closed. She set him on her lap to suckle at her teats. It was of some consolation.

The three names nursed their reborn fathers, and all eyes were between Diamond Tiara's legs, waiting for her turn to finish. She was still breathing heavy in labor, but just below the shallow water, her marehood was still completely closed. Even though she was an adult mare of foaling age, she was still the most petite of the group. The spa twins moved to either side of her.

"Relax," Aloe coached, gently placing her hoof on Diamond's pubic fur. Diamond's contraction made her wince and reflexively close her legs.

"No, no!" Lotus said, putting her hooves between Diamond's knees. "You must keep these spread wide!"

"Let me check on your progress," Aloe said. "Roll over onto your hooves." They helped her to turn and stand in the shallow water. Aloe lifted her tail and spread Diamond's clasped pussy open and the sunlight poured inside. "It looks like you are fully dilated. A few more good pushed and you should be able to get him out!"

"Perhaps squatting?" Lotus suggested. She helped Diamond to the edge of the pool and held her steady while Aloe continued to gently rub her clitoris to help ease her discomfort. "Now push."

Diamond grunted and groaned. With gravity helping, the bulge in her abdomen shifted lower as she pushed her father into her birth canal. With her next push her marehood swelled and stretched. She smacked her hoof against the polished stone patio as she strained.

Rainbow Dash held her suckling father to her teat as she watched the bulbous shape push out of Diamond Tiara. "That better not be a Code Brown."

"Rainbow!" Twilight scolded.

Starlight felt her stomach flip and looked away. "Well, now I can't un-see it."

A couple more good pushes and Filthy Rich splashed down into the water. Aloe lifted him out of the water while Lotus exited the pool and quickly brought over a foam pad for the patio. Diamond Tiara crawled up onto the pad and Aloe passed her father to her hooves. The other mares gently paddled their floats over to the stairs and, with a little help, they also exited the pool.

Miss Harshwhinny had prepared the rest of the patio furniture with extra towels. The fathers-turned-colts carefully walked on shaky hooves as they followed after their daughters, towed along by their umbilical cord. Each of the mares settled into their lounge chairs and toweled dry their little bundles of joy. Each small stallion was then placed on the lounge padding between his daughter's legs.

Filthy Rich sat and admired his daughter's plump teats before suckling. "Just when I thought you couldn't get any more beautiful..."

Each newborn dutifully drained both teats completely. Bow Hothoof pressed snout into Rainbow's colorful pubic fur. The natural pleasure of nursing left the mares feeling somewhat aroused. He felt her engorged clitoris winking against his chin, nearly as big as her nipples. She writhed in her chair as Bow sucked on her clit, stopped only by Aloe's intervening.

"There will be plenty of time for that later, Mr. Hothoof. For now, I'm sure you must both be quite exhausted from your ordeal."

He was hard-pressed to refrain from licking his daughter's delicious pussy. But she was right. Everypony was very tired. He opted to simply rest his cheek against her colorful pubic fur.

"Sleep well, little ones," Miss Harshwhinny said. "The best is yet to come."
