A Womb's Filling Eve

Wordlessly Gentle stepped forward, burying his muzzle under his daughter's side and lifting her up onto her hooves.

"T-thanks dad, I waaa-"

Before she got any further Gentle had put his neck below her midsection, lifting her onto his back and trotting towards the decked breakfast table. Sending all the annoying items to the floor with one quick hoof swipe he placed his daughter on top, earning a puzzled look as she found herself on her back. Quickly he reared up, his hooves landing hard on both sides of her head, his cock now grinding itself up and down her pussy lips. Not waiting for any further objections he pulled back and slid inside once again. Fluttershy meanwhile found herself trapped and penetrated in the same position that had started it all only a few hours before, again powerless to stop the horny stallion on top.

Mother and son walked up behind the copulating duo. Zephyr was already hard again, turned on by the sight of his father rutting his sister, his tail already hitched upwards, presenting his delicious ponut flexing with each thrust. Next to him Posey moved in on her husband's crotch, leaning down to give his testicles a few quick suckles before burying her muzzle under his dock, lubing up his back entrance with her tongue. First circling his outer ring with her tip she then darted forward, slightly parting his asshole as she gave him a good rimjob. Once satisfied she pulled back, gesturing for Zephyr to come closer.

The young stallion didn't need to be told twice, imitating his father and rearing up behind him, resting his weight on his shoulders. Gentle braced against the sudden body on top, pinning down Fluttershy with the weight of two fully grown stallions while still keeping up the assault on her marehood.

Posey admired the view for a moment. Her daughter on the table, legs sticking out on both sides as her husband's hips disappeared between them. Her son close behind, in a similar wide stance as his father before him, his dick hanging in the air just below the table plate and the colliding genitals above. Quickly she dove down and got to work on Zephyr's member, cleaning off her own taste and coating the entire length with her saliva. Her tongue ran from back to front and back again, curling around the green shaft, lubing it up with the sloppiest blowjob she could muster. She opened her mouth wide, closing her lips behind her son's cockhead, swirling him inside while assaulting his peehole with the tip of her tongue. Happy with the result, she released him and used her hooves to guide him into position behind his father.

In a sudden flash of inspiration she spread his cheeks, puckered her lips and firmly pressed them against Gentle's tailhole. She rolled her head left and right a few times before pulling back, a bright red lipstick imprint now decorating his ponut. Playfully she planted a small kiss on Zephyr's tip before grabbing it with her hooves and guiding it against the waiting entrance.

"Now make sure your father can't walk straight for a week."

With that she placed a hoof against Zephyr's flank, pushing him inside his dad. After a moment of resistance his unflared cockhead popped in, firmly encompassed by the outer ring. Zeph's eyes widened, clearly not used to the tightness of a pony plot. Carefully he pushed inwards, for his own and his father's sake.

Unfortunately for he two of them Posey remembered at exactly that moment that she still had a score to settle with her son. The stinging horseshoe mark on her flank reminded her that somepony had been a naughty colt, and naughty colts needed a spanking. Slowly she walked around to the backside of the family train. Rising her front right hoof, she spit in it, carefully took aim, lunged out wide, before connecting her horseshoe with Zephyr's flank, a whip-like crack echoing through the living room.

Zephyr howled as his bottom suddenly burned intensely. The sheer force of the blow drove his hips forward and against a very unfortunate Gentle.

All the air was driven from his lungs as his son's cock straightened out his virgin colon, his anus stretched wide as the entire length, medial ring and all, were shoved inside. Fluttershy wasn't quite sure what had happened, but a sudden forceful thrust drove her entire body further towards the middle of the table, her father now fully lying atop her. Once Zephyr had regained his focus he looked down to see himself stuck completely in his father's backside. Gentle's ponut was pulsating wildly at the very top of his thick base.

He looked around for the culprit, finding his mother climbing onto the other side of the table. Posey lifted her husband's body back up from their daughter, helping him steady his hooves again.

"Sorry honey, the opportunity was just too tempting."

"I bet it was. I'll need an ice pack for that."

"Everything you want. Now move back a bit. And you Zeph, start pounding."

As his father pushed himself further upright, Zephyr relocated his hooves, grabbing his dad around his midsection, just above where his sister's spread legs ended. Slowly he withdrew, admiring the ponut prolapsing outside, clinging to his member tightly. Pushing back inside he was amazed by the tight and warm feeling greeting him as he explored the soft depths. This was certainly a feeling he could get used to, and one his future wife would definitely have to. Angling his thrusts a bit upwards he suddenly drew a sharp gasp from the stallion in front, signifying he had found the right spot.

Now that he was accustomed and had found his father's prostate, Zephyr didn't hold back, pounding away, determined to help his dad sire his next foal.

Posey watched with glee as her son's thrusts synchronized with his father's, pounding her daughter with unmatched strength.

"How do your foals feel, honey?"

"Nnng, they are wonderful, j-just like you."

"Oh, you old charmer. If I had known you were such a bottom I'd have gotten you a strap-on this Hearth's Warming."

"Put it, ah, on the list for next year."

"Will do. Now let me join you there."

Posey slid forward on the table, straddling her daughter between her thighs. Holding her head steady with her hind legs she sat back, planting her dripping horsepussy right on Fluttershy's mouth. Said pony seemed to get the message, licking her mother's marehood dutifully as the fresh air around her was once again replaced by a sweaty body. Posey was clearly satisfied with her daughter's oral skills, grinding herself on the muzzle below as she cupped her husband's cheeks, pulling him in for a deep kiss.

Their family gangbang now complete, each pegasus focused on pleasuring their designated hole. The two stallions each groaned loudly as their hips slapped against their mate, while Posey moaned with pleasure every time Fluttershy licked her just the right way.

Zephyr was the first on to reach his limit, the day having taken a toll on his stamina. He gave Gentle a few extra long thrusts against his prostate before bottoming out and releasing, painting his father's insides a bright white. That in turn pushed him over the edge, his son's deep tissue massage helping him give his daughter below another massive creampie.

As her husband sighed into her mouth, Posey could not contain her excitement for another new family member any longer. She spread her legs as wide as she could before creaming herself on her daughter's muzzle. Fluttershy meanwhile was completely overwhelmed by an onslaught of stimuli hitting her from all sides. While she desperately gulped down wave after wave of marecum squirting from her mom's pussy her dad very clearly came inside her again, no doubt adding another foal to the mix. Her body simply gave in and she came around her father's cock, screaming her own orgasm back inside Posey.

As each of the family members rode out their orgasm in one another their movements slowly died down. The first one to dismount was Zephyr, slipping out of Gentle's ponut, followed by a wave of cum dripping from his backside. Next was his father, drawing his softening dick from Fluttershy's pussy, equally followed by a river of white flowing from her entrance.

Posey didn't stand up, but at least raised her plot in the air to give Shy some much needed oxygen. Instead she leaned forward, eagerly watching her daughter's belly for any movement. Seconds went by as she stared at the fur intently, trying to keep all free spots in between the existing marks in focus at once. Her son and husband joined her, all three waiting for Gentle's swimmers to do their job.

"What happened, did you not cum inside?"

"Nope, that was as hard a nut as always. Maybe she has no room left in her?"

"Nonsense, with her pudgy belly she could carry a full herd."

"Uhm, excuse me, I can hear you."

"Fluttershy, dear, what's the problem? We are waiting for your fourth sibling."

"Oh, uhm, I really think three is enough, considering they are from my father and brother, and I didn't really want-"

"What a load of horseapple, here, let me help."

Determined Posey placed her hooves on Fluttershy's lower half, kneading her fur with a precision only a soon-to-be grandmother could have. Her sensitive hoof frogs could feel the foal batter sloshing around inside as she massaged it upwards, away from the entrance were the precious liquid could leak out. Bringing her face down she alternated between her daughter's teats, suckling on her nipples to give her body the right idea. With one hoof she clopped away at Fluttershy's marehood, grinding down on her clitoris every time it revealed itself, while her other continued the womb massage. Her mates looked on flabbergasted as she stimulated the mare below her seemingly everywhere at once.

A sudden bright light shone directly into Posey's eyes, reflecting from them with a greedy shine. Colored spots started appearing on Fluttershy's lower belly, three distinct shapes appearing on the yellow ground. A group of three more white clouds joined the other marks as Posey let out a victorious squeal. Fluttershy sighed before being silenced by another squirt of motherly cum hitting her in the muzzle.

Zephyr and Gentle smiled at each other as they both admired their work, each of their two paternity marks now adorning their mate's belly.
