A Womb's Filling Eve

Warning: watersports chapter

"What a fantastic job you two did. You made me the proudest pony in all of Equestria today!"

"Thanks mom, you were amazing too. How did sis do?"

"Oh, she took it like a champ. Can't wait for her teats to grow though, they're a bit flat for my taste."

"Great minds think alike."

"Huh?"

"Nothing."

"Alright my two studs, do you think you have another round inside of you?"

"Guess so."

"Me too."

"Perfect, because I'd hate if one of you felt unfairly treated. Let's think about this for a moment. Zeph got to buck two foals inside his sister and one inside me. Gentle, you have only one inside her right now. So it would make sense if you went right back in and gave her quadruplets, and when you double penetrate me with Zeph later you can have another one with me."

"Sounds fair to me."

"Sure thing. But what should I do in the meantime?"

"I'm sure your father could use some help with breeding Shy again so early, you could lend him a helping dick with a prostate massage."

"A family train? Good idea."

"I didn't know you were this kinky, honey. Be a dear and lube your son back up before he shoves it up my tailhole."

"I will. You'll probably still walk funny if my sore pussy is any indication."

"Ughh."

The yellow heap on the floor slightly stirred.

"Oh right, and somepony should wake Shy."

Posey remarked, looking back at her daughter squirming inside the puddle.

"And clean her."

Gentle added.

"I think I know how to do both at once. And we don't even have to carry her to the shower."

Zeph answered with a devilish grin on his face, stepping up to his sister's head an pointing his still unsheathed member at her muzzle. With a sigh of relief he unleashed his bladder, a hot stream of piss shooting from his length and hitting her square in the face. Fluttershy suddenly stirred, the liquid clearly doing its job.

Gentle looked on unsure as his son gave his sister a golden shower, but Posey next to him just shrugged and turned around. Aiming her backside towards her daughter's chest, she raised her tail and released her own torrent of pee, joining her son to hose their new toy down.

Seeing no objection from his wife Gentle decided to follow their example, closing the circle around the stirring pegasus on the floor, pointing his erection towards her crotch. His stream hit her right on the crotchboobs, and he made sure to guide it all over her nether regions, first cleaning off his own creampie from her pussy, ponut and dock before moving back up
and using his gush to uncover their paternity marks from below the cum coating.

Further above Posey had revealed Shy's now not-so-fluffy chest fluff again, making sure to get all cum stains off her neck that kept flowing down from Zephyr washing her face.

Said pony was clearly relishing the opportunity to get back at the sibling that had pissed him off so many times before. He had succeeded with cleaning her face and rousing her from her sex-induced coma quickly, but his bladder was still not even close to empty.

Fluttershy in the meantime was now fully awake again, unfortunately still too weak to get up on her own. She had to squeeze her eyes shut to protect them from the golden liquid spraying from her brother's dick, and so could only feel the rest of her family being hard at work further below. Her mother's stream was now steadily aimed at the center of her chest, warm rivers of urine streaming down on both of her sides, diluting the wet puddle around her and soaking into her primaries.

Even lower still her father was done cleaning her teats and belly but seemed to be unhappy with the state her sloppy horsepussy was in. First trying to pressure wash her snatch from the outside, he quickly changed his mind and simply jammed his member back to were it just came from, peeing directly inside her vagina.

His son meanwhile had other thoughts.

"Ah buck, why do I always have to pee so much after sex?"

"That's just your body cleaning out your urethra to prevent infections, Zeph."

"Oh right. But her muzzle is already soaked and the puddle is starting to reach my hooves."

"She still has a mouth, you know."

"Good idea!"

"I am just full of good ideas today."

"Not just good ideas."

Zephyr winked at her and turned his attention back, wrapping Fluttershy's dripping mane a few times around his hoof before pulling her face up from the floor. Momentarily out of the constant stream she opened her eyes, just in time to see a familiar green horsecock rapidly advancing towards her mouth. Unfortunately it hung slightly open from the force pulling at her mane, and the next moment the dick slipped inside, forcing it wider open and pressing down in the back. A sharp, aggressive taste assaulted her taste buds as Zephyr's hot piss filled her mouth, bulging out her cheeks and running down her throat. Her stomach was now getting an equal filling as her vagina, and as she hung under Zephyr's side, head held steady by his hoof in her mane and his dick in her mouth, she could do nothing else but gulp down the seemingly endless stream of horsepiss.

Gentle stroked the base of his cock, careful to get every drop inside his toilet mare, before admiring his son's technique.

"You know, that's not exactly the kind of spitroast I had in mind, but it works just fine."

"She swallows piss like a champ. I think I'll have to use her mouth more often from now on."

"Don't let me stop you. By the way, Posey, you are pissing like a waterfall."

"Thanks, that's all the cider from last night. And remind me to get my cooking funnel later, I want to piss in her ass the next time."

One by one the ponies finished, each of them stepping back to admire their cleaning efforts. Zephyr's stream cut off last. He forced out the last few droplets, then used her soft tongue to clean his tip. Unceremoniously he let go of her mane, Fluttershy weakly falling back into the now mostly yellow pool.

Coughing, she flimsily tried to sit up, but her hooves found no traction and sent her right back down, splashing around like a fish on land.

"Puh, that's better."

"Nice job, Zeph. Good as new I would say."

"You too, mom. And what a lucky coincidence she got your coat color, or else this would be quite awkward."

"That's true, she is our perfect little Guttershy. Now Gentle, ready to make me another grandfoal?"
