Silly Filly Spa

"Does everypony have their arts and crafts kit?" Miss Harshwhinny asked. All of the present stallions vocalized to the affirmative. "Very good. And you have your seat cushions from the orientation?" Each stallion had in his hoof the seat cushion that their daughters had been sitting on from the orientation room. "Excellent! Get yourselves prepared!"

Each of the stallions held the seat cushion to his nose. Their daughter's cocktails had, in addition to the alcohol of their choice, a liberal dose of Zesper. The mare libido enhancement potion that simulated the effects of estrus. Each of the stallions took deep breaths of the scent of their daughters in heat. It gave them the hardest erections they'd had since before they'd become fathers.

Miss Harshwhinny admired her class's performance and smiled. "And begin!"

Each of the stallions hastily combined the active ingredients of their kit and poured it into a tube. Then they shoved their dicks inside to create and exact mold of their penis.

"Think about how good it's going to feel inside your little fillies!" Harshwhinny coached. They kept huffing the cushions to keep themselves rock hard. "And... that's two minutes!" They all pulled out and then inserted the internal dildo hardware and added the silicone to the mold, giving it enough time to cure.

"While you're waiting..." Harshwhinny brandished a magical artifact. Each stallion sat up on top of their work bench as she came around to hold it over them and shrink them to the size of a pencil eraser. While each of the dildos were given a liberal coating of personal lubricant, her unicorn assistant used her magic to carefully lodge each of the stallions into the tip of their own replica dildos. The dildos were placed on a tray and Lotus carried them to the other room.

"Party favors!" she said as she returned to the massage parlor with the tray. The other massage ponies each took one and resumed their work. Each of the stallions waited patiently in the cramped space of their dildo urethra with their hooves pinned to their sides. The tube was barely bigger than their head, stretched around their torso. But they could at least see out of the small opening in the tip. Careful organization made sure that they each found their way to their own daughter's massage table.

Twilight looked skeptically at the 'massage aides'. "Those are just dildos."

"Aww, buck yes!" Rainbow Dash said. From inside the tip of his dildo, Bow Hothoof watch his daughter eagerly lift her tail and spread her legs. He felt his stomach do a flip from the sudden acceleration of being shoved forward up against her marehood. Her eager wetness soaked his entire face and head as her vagina stretched around the tip of his dildo. As soon as she did, he lurched forward inside several inches before being thrusted deeper.

"The brochure mentioned complete-release massages!" Diamond Tiara said, spreading her legs eagerly. Filthy Rich looked out from inside his dildo as his daughter eagerly lifted her tail. This time it would be for him. The masseur holding him pushed him forward against his daughter's pussy. He expected more resistance form his little filly's marehood, but he was pushed inside with disappointing little resistance. Her wet vagina rushed around him as he was pushed in and out to fuck her.

Night Light rode along anxiously inside his own dildo. His daughter's tail stayed firmly wedged between her thighs. "Is this normal!?" Twilight asked.

"You only live once, Twilight," Starlight said, relaxing against the massage table. "Maybe try not to worry so much?"

Firelight watched his daughter lift her tail and he felt himself rush forward. He likewise expected resistance from his lesbian daughter, but he was able to plunge inside the depths of her vagina with relative ease. Her tried to not think about whatever plastic competition he had from Trixie as his daughter's pussy swallowed him.

Night Light watched the hooves of Twilight's masseur on the inside of her knees, beckoning her to spread her legs. She clearly needed very little convincing to relax. Once she did, a hoof lifted her tail and he was lurched forward. His face, and the well-lubricated dildo, pressed against her marehood. It took a moment for her inexperienced loins to stretch and he was pushed inside. After a few small thrusts, it tested her depth. Night Light's face kissed the tight pucker of her cervix. Twilight moaned out loud at it filled her completely perfectly. Its length and girth filled her just right to give her just enough of a stretch to feel satisfying without feeling painful. Like it was custom made for her.

"This is nice..." Filthy Rich could hear Diamond's voice purr around him.

"This can't be normal..." Night Light heard Twilight's concerned voice say. But his dildo didn't stop thrusting in and out of her.

Firelight could hear Starlight purr. He could tell that she was getting closer to cumming. Each of the massage ponies expertly worked the dildos in and out of each mare, reading their reactions and hitting them in just the right spots.

Even though he had been assured that it was impossible, Bow Hothoof held his breath to keep from drowning in marecum inside his daughter's pussy. "F-fuck!" Rainbow Dash moaned, squirting her orgasm onto the massage table. "That was quick!" Aloe said as she pushed the dildo as deep as she could. Bow's face was pressed up against Rainbow Dash's stretched cervix as she came. Aloe pressed down on the plunger and Bow felt the building pressure of the cum lube behind him. In an instant he has launched inside of his daughter's uterus before she came down from her climax and her cervix sealed shut behind him.

Filthy Rich was next, as his daughter's cervix opened briefly for him to get pumped inside. Firelight was launched inside of Starlight's womb shortly after.

"So what exactly are you..." Nightlight could hear his daughter's inquisitive voice humming around him. Her masseur quickened his pace. Nightlight felt himself start to get dizzy. But luckily, Twilight's body quivered and her pussy dripped with extra wetness as she finally came. Night Light was pushed as deep as he could go before the pressure inside the tube spurted him safely inside of his daughter's womb before her powerful cervix muscles sealed him inside.

In the complete darkness, Night Light waded through the large pond of cum lube sloshing around inside Twilight Sparkle's uterus; his hooves desperately feeling around in the viscous liquid, searching for what he was looking for.

Twilight Sparkle panted and looked at the other three mares on their massage tables. They all had similar looks plastered on their faces. Diamond was sweating profusely. Rainbow's eyes were going off in different directions. Starlight's tongue was hanging out.

Once she had climaxed, Twilight, like the others, was left there, with the dildo still lodged deep in her pussy. "Your gifts to keep," Lotus said as she and the other massage ponies departed. Twilight could barely focus her magic. She reached behind herself with shaking hooves to slowly pull it out of herself. She held it in front of herself to look at it. For something that she assumed to be standard issue, it was incredibly detailed in its texture and appearance.

Diamond Tiara was similarly looking at hers.

Rainbow Dash swiped hers at Starlight's. "Sword fight!"

"Rainbow!" Twilight scolded.

"Mine's longer!" Rainbow teased.

"Well mine's thicker!" Starlight spat back.

Twilight noticed that indeed, the two toys were visibly different. Rainbow's was longer, if a bit more slender. And Starlight's, while shorter, certainly had more girth, similar to her own. But they were all of them dwarfed by Diamond Tiara's beast of a toy.

"Damn, Tiara!" Dash said. "How the hay did you get that monster inside you?"

"Earth pony magic!" she said before winking and wiggling her hips.

Twilight Sparkle felt neither pride nor shame in her own toy. It had fit her perfectly.

Rainbow Dash flexed her wings and stretched her hooves on the massage table. "Well, I'm relaxed now!"

"Ladies, if you would?" Miss Harshwhinny beckoned them from the exit.

They each slowly climbed off of the massage table and carried their toys as they followed her back to the main hall. The eight padded chairs were replaced with four lounge recliners. Harshwhinny directed Rainbow Dash to the chair with the plexiglass barrier in front of it. They each took a seat and relaxed.

"Now that everypony is here-" Miss Harshwhinny began.

"Everypony?" Twilight interjected. "Where are our fathers?"

"Everypony is here," Miss Harshwhinny said.

Rainbow Dash squinted and looked around the room. "Okay, I know I usually set the bar pretty low, but... I'm confused."

Miss Harshwhinny looked at Twilight. "Ms. Sparkle, I believe your brother is quite familiar with the process..."

"Oh no..." The color drained from Twilight's face. Inside her uterus, her father finally found what he was looking for.

"Oh yes!" Night Light said as his hoof grasped her umbilical cord and held it to his belly button. It plunged into him and fused his body to hers. Twilight's knees pulled up to her chest as she squealed and came again, wetting her lounge chair.

Starlight smirked. "Damn Twi, and here I thought I was- OH MY GOSH!" Starlight moaned, feeling herself cumming again.

Diamond Tiara looked confused. "So is that a unicorn thing or-oh-OHH!" she groaned in orgasm.

"Okay, now I'm extra confused," Rainbow Dash said. Inside her womb, Bow Hothoof finally found her umbilical cord and held it to his belly. "Oh my GOSH!" she squealed, squirting a jet of her marecum against the plexiglass barrier.

Miss Harshwhinny adjusted her glasses as Rainbow Dash finished spurting. "As I said, everypony is here." She stepped over to the podium at the front of the room and turned on the projector. The first slide featured the B.C.C. Banana Cabana Club logo emblazoned above a beautiful panoramic photograph of the resort. She went to the next slide and the B.C.C. text changed from the Banana Cabana Club to the Silly Filly Spa.

"Princess Twilight?" Harshwhinny asked, "Perhaps you would like to enlighten the class?"

Twilight held up her dildo and looked at the opening in it. Then she looked down at her body and held her belly with her hooves. "Our fathers are inside our wombs!"

"..."

"..."

"... Um, what!?"

"During our massage," Twilight explained, "Our father's were shank down to the size of a pea and then they were pumped inside our wombs!"

"How do you know that!?" Starlight asked.

"My mom did the same thing to my brother!" Twilight said.

"Okay, I'm definitely feeling something!" Diamond said, shifting in her seat.

"Yeah, like butterflies in my stomach!" Starlight added.

Rainbow Dash couldn't keep herself from rubbing her pussy with her hoof.

"It means your father masturbating inside your uterus!" Twilight said. She felt a tingle run through her body. "Dad! That wasn't a suggestion!"

Twilight focused her magic to try to teleport her father out of her womb. Her horn crackled and fizzled. "Ow!"

"Ah, Princess Sparkle, I meant to warn you, and Starlight," Harshwhinny said, "Your magic will be quite inoperable during your pregnancies."

"Yeah, I noticed," Starlight said, rubbing her horn.

Diamond clenched her legs together on her hoof in her crotch. "Is my dad really jerking off inside me!?"

"Let's find out, shall we?" Miss Harshwhinny offered, holding up four smooth, modest sized dildos. She gave one to Diamond to put inside her vagina. "Mr. Filthy Rich? Can you hear me? I've inserted a microphone inside your daughter's vagina. Speak now and we should be able to hear you.

"Oh, uh, hello?" Filthy Rich's tinny voice crackled from the small dildo speaker.

"Daddy!? You're inside me!?"

"I'm sorry sweetie. But I've spent so much of my life taking care of you. And you go around being a whorse for everypony else. It's not fair! I just wanted you to know what it was like to have to take care of me for a little while."

"What!? No! Get out! Get out!" Diamond Tiara flexed her muscles, pushing out the microphone, and nothing else besides a fart. She blushed. "It wasn't me!"

"I'm afraid you will not be able to push him out until you've come to the full term of your pregnancy with him," Harshwhinny explained.

Rainbow Dash perked up, "I can't be here for eleven months!"

"It's an accelerated course," Harshwhinny said. "Just five days and then he'll be out."

"Like a full size foal!?" Diamond asked. "He'll ruin my mare bits!"

"You'll physically recover just as quickly," Harshwhinny assured her. She put the next microphone inside Starlight Glimmer. "Mr. Firelight? Can you hear me?"

"Oh, this is fantastic!" Firelight's voice crackled from the tiny speaker sticking out of Starlight's vagina. "I haven't had an erection like this in ages!" Starlight couldn't keep her hoof from rubbing between her legs, making her pussy gush fresh wetness as she came.

"Mr. Firelight, did you just ejaculate inside your daughter's uterus?" Harshwhinny asked.

"So much!" he cheered. "It's like a Jackson Pollock painting in here!"

"Dad!" Starlight cried, "What if you get me pregnant!?"

"That's kinda the idea," Firelight admitted.

"Dad!"

"Don't worry, dear," Harshwhinny said as she pulled the microphone out. "He can't actually get you pregnant while you're already 'pregnant' with him."

Rainbow Dash was panting and sweating. Miss Harshwhinny put a microphone inside her vagina. "Mr. Hothoof, it looks like your doing quite a number to your daughter."

"Oh, uh, hello," Bow's voice came out of Rainbow's vagina. "Yeah, what can I say? I'm drenched from head to hoof in the estrus of the worlds best flier! Of course I'm gonna jack off in here!"

"Dad... you're really jerking off inside me!?"

"Oh, champ, I'm gonna be doing this all week! F-fuck! Hngh!"

"Daddy!" Rainbow Dash quivered and her back arched and the microphone was ejected out of her pussy as a fresh jet of her marecum squirted out in time with her father's climax inside her.

Twilight Sparkle panted as Harshwhinny slid a microphone inside her vagina. "Dad! I don't have time to get pregnant! I have a nation to run!" She could feel her pussy dripping. "I know you said you wanted to reconnect, but I didn't think you meant literally!"

Night Light slid around inside Twilight's rocking womb, pressing his face against her walls, licking her insides as he clopped himself silly. "Oh, Twilight! This is the happiest I've been in years! As happy as your mother has been. Please, just let me have this for a while! Hngh!" Night Light's hoof was a blur on his dick as he orgasmed, spurting his cum in thick ropes, spraying her insides white with his cum against the inside of his daughter's womb.

Twilight clutched her belly as she felt her father ejaculating inside her uterus, knowing there was nothing she could do to stop it. She writhed in her lounge chair as she orgasmed, squeezing out the microphone and drenching the mesh fabric with her marecum.

"Gentlecolts," Miss Harshwhinny said to their collective bellies, "I know it must be hard to resist, surrounded and drenched in a mare in heat. Especially your own daughters. But I would ask that you refrain at least long enough for these poor girls to at least be able to walk back to their bungalows for the evening." The four mares panted and looked at Harshwhinny as they caught their breath. "This way, ladies." She showed them to the bungalow courtyard and resort huts
with luxury bed. "Good evening ladies. Rest well. Group therapy will commence tomorrow morning after breakfast."
