Silly Filly Spa

Rainbow Dash rolled over up in her cabana bed and blinked at the morning sunlight peeking though the sheer drapes. She reached her hoof over to the night stand to grab a couple bananas to eat quickly. She slowly shifted herself upright and cradled her heavy belly while she ate. She barely got the second one down before she lurched forward and dashed to the bathroom to retch into the toilet.

"How's the morning sickness today, Squirt?" Bow asked from inside her belly. Her accelerated pregnancy meant that he was already large enough for his voice to be heard through her belly without a microphone. But it also meant blitzing through all the other aspects of pregnancy.

"Bananas help," Rainbow said, wiping her mouth and flushing.

"Because of the electrolytes?" he asked.

"And they taste about the same on the way up as down," she said, walking out to the cabana quad. Bow laid reclined inside her womb, sliding back and forth with the sway of her belly under her like a hammock. His idle hooves slowly stroked himself. Rainbow's clitoris winked and her knees trembled. "Dad... can you at least wait until after I've had a regular breakfast?"

"Sorry Dash. I wasn't going to go all the way," he said.

"It's still distracting."

"You think it's distracting for you? I'm practically swimming in your estrus inside here. I've lost count of how many times I've cum inside here and I'm still hard!"

Rainbow walked over to the breakfast bar and took a big plate of bagels, donuts and muffins. Her strict diet went right out the window when she started eating for two. So she decided to indulge herself in lots of carbs.

The other three mares had already been awake for a while. Diamond Tiara had affixed her father's dildo to a large vibrating pad. The entire shaft vanished up inside her as she sat down, resting her belly on an accompanying pillow while she drank a fruit smoothie.

Starlight Glimmer joined Twilight Sparkle on the large patio futon. "My dad want to talk to yours," she said. Twilight rolled her eyes and leaned back, spreading her legs. Starlight squatted across from her and pressed her pussy up against Twilight's.

"Night Light?" Firelight's muffled voice travelled through the mares' bodies.

"Firelight? Is that you?" Night Light replied.

"Yeah! How's it going in there?" Firelight asked.

"Oh, it's fantastic! I feel so young and rejuvenated! How about you?"

"Same! I haven't been this hard since Starlight had her first heat."

"That must have been tough, being a single father. At leave Velvet used to be more receptive to dealing with me during Twilight's heats."

"Yeah. It was a lot of solo time for me yanking the crank in the laundry room with her damp bedsheets."

"Dad!" Starlight balked.

"Huh. And here I thought Shining was volunteering laundry duty to hide his own messes," Night Light said.

"Could be both," Firelight said. "But did he really get your wife pregnant?"

"Yeah."

"That's rough, buddy. But I can't really blame him. I would have loved to put a foal in my mother, too."

"Of course! What colt doesn't!?" Night said. "I thought sending him off to the Royal Guard Academy would have avoided all that."

"But hey, all's well that ends well, right? I mean you're inside your alicorn daughter! That's pretty amazing!"

Nightlight shifted himself against the inside of Twilight's womb. "I don't really have a frame of reference for comparison. I should think it's about the same for you, too. Smooth muscle interior constantly slick with mare cum that keeps your dick hard constantly?"

Firelight rubbed his check against the inside of Starlight's uterus and smiled. "Yeah, pretty much."

"Dad, can we wrap this up?" Starlight asked. "My coffee is going right through me."

"Yeah, mine too," Twilight said.

Night Light smirked. "Fire one!" He pushed his legs against Twilight's bladder, making her lose control.

Starlight shrieked. "Twi!"

"Dad!"

"Return fire!" Firelight yelled, pushing his hooves against Starlight's bladder.

"Dad!"

Twilight squirmed away from Starlight's arc.

"What the hell are you kinky bitches doing?" Rainbow Dash asked.

"It's not our fault!" Twilight said, blushing as she crossed her legs.

"Our dads' were having a squirt-gun fight! Like a couple of immature colts!" Starlight scolded. The two unicorns walked through the water sprinkler on the lawn while one of the resort staff rolled their eyes as they hosed down the weather-proof futon.

Miss Harshwhinny joined them a short while later. "Good morning, ladies! Our first activity this morning will be getting you some vitamin D during todays group therapy."

"Way ahead of you," Diamond Tiara said, turning off her vibration pad and slowly lifting herself off her dildo.

Harshwhinny chuckled. "Very clever. But I do mean actual vitamin D. The kind that you get from the sun."

"So, what?" Rainbow asked. "We're just going to be sun tanning?"

Harshwhinny smiled. "It's a little more involved than that." She directed them to follow her. "This way." The pregnant mares waddled after Harshwhinny down to the resort's beach. She directed them to the semi-circle of reclining lounge chairs. They each took a seat and laid back. Harshwhinny reclined Starlight's chair further back until she was slightly inverted with her hips above her head. There were secure shoulder pads like on a rollercoaster, that kept her from sliding back. "Now just spread your legs and try to bring your ankles back to your cheeks."

Starlight hesitated. "Uh..."

Harshwhinny helped guide Starlight's legs until she was practically in a breeding press. "Hold these for a moment." Starlight's hooves grabbed her ankles. Harshwhinny took a large smooth glass dildo and slid it all the way into Starlight's spread pussy. Starlight could feel the warmth of the sun shining where it had never shown before. Inside her uterus, Firelight could see the dim red light of the sun glowing through her cervix wall.

Harshwhinny moved over to invert Twilight. She looked over at Starlight's stretched, pussy. The entire inside of her vagina was completely illuminated and she could easily see deep inside her. "Uh, I'm feeling a little exposed out here," Twilight said.

"Relax, Princess. This is a private beach." She guided her legs back and gave her a similar glass dildo before moving on to Diamond Tiara and Rainbow Dash. Dash strained to look over her round belly up at the sunlight refracting through the glass cylinder, making her chromatic pubic fur briefly look extra colorful before slid inside her and rested against her cervix.

Diamond Tiara and the other mares all looked at each other with their stretched vagina's pointed at the sun. "So how long do we have to sit like this?" she asked.

Harshwhinny started the timer. "Just fifteen minutes."

Starlight Glimmer could feel the weight of her father inside her womb shifting inside her abdomen, pushing up against the rest of her internal organs, making it a a little more challenging to breathe.

Twilight looked away from the sunshine. "I really hope Celestia can't see this."

"That sunlight feels great!" Bow Hothoof's muffled voice said. The other mares looked over at Rainbow Dash squirming uncomfortably in her seat as he continued what he had started earlier that morning. Her vaginal muscles flexed and squeezed, making the glass cylinder push out slightly before sliding back inside.

Miss Harshwhinny took two big steps back.

"F- fuck! Dad!" Rainbow's legs quivered as a jet of her marecum shot vertically straight up out of her pussy. The droplets twinkled in the sunlight for a second before it arced back downward, splashing herself in the face. She winced and sputtered from her face-full of friendly fire, panting to catch her post-orgasm breath. "Well, now I know how AJ feels about that."

A short while later, Harshwhinny's timer went off and she walked around the group to pull out their pussy prisms, and reset their chairs. Each of the mares relaxed and slumped forward, sighing and finally catching a deep breath. "Who's ready for lunch?"

~

The four guests paddled through the cool water over to the poolside bar. Unfortunately, alcohol was off the menu for the pregnant mares. But everything else was fair game. They sat side by side on the submerged bench in the shallow water as they ate their personalized food orders. The bench had built-in pulsating massaging water jets that were very particularly located. All four of them just held on to the edge of the bar, barely able to focus on anything other than just chewing, and trying not to black out from orgasming. After thoroughly stuffing themselves with the lunch buffet, they were content to stay off of their hooves and just float in the water.

The warm afternoon sun shifted behind the canopy of trees. The mares waded out of the shallow end of the pool and toweled dry as best as they could before heading to the evening group therapy. No longer needing the vaginal microphones, the stirrup lounge chairs were replaced with large, padded cots for the mares to lay on and support their very gravid bellies.

Miss Harshwhinny sat in the center of the group. "Now we've talked a lot about being sympathetic to your fathers' plight. The strength of will it takes to resist constant, overbearing, primal pressure to breed their own daughters as soon as they go into heat. But I want to take time during this session to her more from the daughters. And dads, I want you to listen closely. Why don't we start with you, Twilight?"

Twilight hugged her belly. "Dad, I..." she tried to find the words. "I know things in our family have been... strained. Especially ever since Mom reclaimed Shining for herself. That's not fair to Cadance and that's not fair to you. And..." she trailed off. "And I know it's too late for me to say it now, but it felt unfair to me, too. But I already felt that way when Cadance married him out of the fucking blue!"

She took a deep breath to calm herself. "It's not that I was strictly not attracted to you. You're objectively attractive! You're kind and sweet and... I could tell why Mom married you. And that was really it. You were married. And then so was Shining. I I became a princess. An alicorn! I didn't think I'd even be able to do that and have a foal, too. But if Cadance can do it..."

She sighed and continued. "Part of me still held out hope that I could convince Shining to just be a donor. Because I just couldn't see myself even being able to date a regular stallion now. But..." she rubbed her belly. "I guess things are different now."

"I love you, Twilight," Night Light's muffled voice said from her belly. "You know there's nothing I wouldn't do for you."

Miss Harshwhinny leaned over and put her hoof on Twilight's. "Princess, alicorn or not, life is a challenging road for everypony to walk. Together, I'm sure you will find your way." She rolled her chair over to the next cot. "How about we hear from our Wonderbolt next?"

Rainbow Dash chuckled. "You know, it's funny. I always thought I'd be the one helping AJ having foals with Big Mac. I used to tease her all the time about it. She hated it. And then he went and married Sugar Belle, which shut me right up. I kinda just accepted that we'd either never have foals or maybe adopt someday, but..." she trailed off. "Before, I could never see myself being a mother. But now..." She smiled and rubbed her belly. "It's something I really want. I think all that teasing I did was just me projecting, being an only-foal. That taboo just seemed so attractive. I'm not asking you to leave Mom to do it, but-"

"Say less, Dashie," Bow said. "It would be my honor!" Tears of joy streaked down her cheeks.

Harshwhinny looked at Starlight Glimmer next. She looked down at her belly. "I know I didn't make things easy for you. But at least part of me understood that things were harder for you, raising me by yourself without Mom. But I never realized that once I got my cutie mark..." Starlight blushed. "Looking back now, I must have put you through Tartarus. I was humping every pillow in the house! I made you take me 'toy' shopping. I must have reeked for weeks. Oh my gosh! I went through that bob-tail phase because I enjoyed the breeze. You had to deal with me being on full display all summer, complaining about not having a coltfriend to douse my heat! And that whole time..." she trailed off. "No wonder you were always wearing that suit. You must have been in agony! How did you not-"

"I would never!" Firelight said. "You were my little filly. I would have fallen on a sword first!"

Starlight asked nervously, "But... if I had asked?"

"In half a heartbeat!"

Harshwhinny looked over at Diamond Tiara. "Dad, I'm sorry you married a bitch."

"Tia-"

"No, I mean it, Dad!" Diamond continued. "You deserved better. We deserved better. I always hating having to compete with her for your attention! I knew I would always lose because she could just suck your dick and you would forget what a shitty pony she was. I hated her for that! I hated that she could just trick you so easily. And I..." She reached over and picked up his replica dildo. "I always thought I'd never be able to compete with that."

"That was never your responsibility!"

"You know, I didn't start whorsing around at school to get your attention," she said. "I did it to piss her off. I wanted to use her own game against her. I just didn't realize how well it would work... I'm proud of you for divorcing her."

"...But?"

"I'll behave, but you have to as well!" Diamond said. "I don't want to hear any more rumors about you porking your secretary, or flirting with Silver Spoon!"

"That lying bitch! I wasn't flirting with her!"

"I mean it Dad! I'm not ready to have foals yet, but I will be someday. And if you want to have any part of that, then you need to swear that you'll be loyal."

"I do!"

"Say the words, Dad. Say the words that Mom made you say for her!"

"... Hippitty, hoppitty, my dick is your property," he said.

Diamond Tiara looked at the replica dildo in her hoof and grinned. "I know."

"But let's all remember," Harshwhinny interjected, "that any relationship is a two-way street. If Diamond is going to make her father's penis her property, then in all fairness, she should extend him the same courtesy, giving him a place to put it as often as he needs to." She adjusted her glasses and looked at how wet Diamond Tiara's pussy was. "Which, upon closer inspection, appears to be quite often. You need to be prepared to accept that responsibility before demanding exclusive rights to it."

Diamond Tiara rubbed her belly. "As long as you keep buying me Moon Tea..." she grinned. "Anytime, anywhere."
