Swingers Party (Patreon)

 Posey Shy was always content with what she had, with a loving husband, two healthy children, and an overall fulfilling life. She was also elated when she got to know the mothers of the friends her dear daughter Fluttershy had (including the Cake family through Pinkie Pie), and one by one they slowly became a part of her life as close friends as well.

Having previously known her through Fluttershy’s close friendship with Rainbow Dash, longtime friend Windy Whistles was a great help in getting to know the others. More and more she gradually found herself amongst her own little circle of close friends as well as a part of more social events alongside them, including ones she was a regular participant in but found herself either working with or amicably competing against the others in events like fundraisers and bake-offs.

Things were virtually no different for the now massively milk mammaried mother post-bimboification, with a little flirting here and there. At least until one day, when she and her husband were invited to a private hotel resort with the other parents, excluding the Cakes due to prior arrangements and their infant children needing to be tended to.

It seemed like a wholeheartedly wonderful experience to spend time together and bond further to Posey, until the full description of everything they were planning to do was laid down to her as they revealed the ensuing "swingers party" waiting to be hosted there. After getting over the initial shock and blushing fit, she let the others ease her and Cirrus into the idea of attending with the promise of letting things go at her own pace and promising not to force her into anything that might be out of her comfort zone.

With a defeated sigh, Posey and Cirrus agreed to come. Following a prolonged goodbye to Fluttershy and Zephyr as well as a short carpooling trip, the five pairs had arrived and the process of checking into a room went by quick. The initially mild, but encroaching nervousness for the motherly MILF of two only began when she was escorted by a hotel employee to a rather spacious sauna where, having swapped her tight-fitting apparel with some towels, the other MILFs were waiting for her to join them.

At first, it almost felt like an introduction to an otherwise tame book club to Posey, but with the surrounding sauna steam doing wonders for her skin. Starting to relax, she and the other mothers talked and gossipped about various stuff, starting with innocent subjects like how the others met each other (Velvet and Cloudy at a P.T. conference, Cookie ordering some comfort food at Sugarcube Corner, Windy and Bow Hothoof meeting the Sparkle parents during a joint skydiving trip, Hothoof and Hondo’s "budding bromance" over soccer, Cirrus impressing Igneous with his knowledge of the Earth during a chance meeting at the local market, etc.), and how they and their families were doing recently.

Then it went to more risque and sometimes downright lewd topics regarding their sex lives and keeping their collectively voluptuous bodies looking trim that led to more than one touchy-feely experience (and more than a little spilt milk on Posey’s part when it came to their "breast inspection"). It was at this point that the already poorly concealing towels were discarded, and everyone in the room had a full, uninhibited view of each others bodies.

A slightly embarrassed, but still elated Posey didn’t even hear the sauna door open, only the brief gust of cooler air against her bare form enlightened her to the room’s five new occupants. It was the other husbands, who lined themselves up with their initially flaccid lengths erecting in the presence of their spouses. They were ready and raring to start to the delight of the wives, save for the ever-lactating mother of two.

To Posey, her current feelings were comparable to a child about to be vaccinated for the first time. All the encouragement in the world from her fellow MILFs had left the milk-laden mother somewhat at ease prior to what was currently being presented, but now it had gone and been replaced with a heart-pounding loss of composure that even Cirrus’ presence could barely mitigate.

But buried under Posey’s deep anxiety was the undeniable eagerness gradually welling up at the sight and smell of so many cocks in her presence, and Cookie could gleefully tell. The former even seemed mesmerized by the quintet of engorged manmeat hovering so close to her blushing face and showing off their varying sizes and girths, to the point that she even started drooling a bit at the brief thought of being penetrated by all five at once.

But Windy and Cookie also noticed their shy friend’s indecisive nervousness, and instructed all but two of the boys to give her some breathing room (though the musky smell of erect cock was still omnipresent), and Bow Hothoof and Night Light were at the ready while the rest were eagerly pulled away by the other MILFs. Cirrus looked and felt just the same as his wife, just as nervous but equally as aroused as Windy grabbed and gently pulled him away by his pulsing erection.

Now it was just her and Cookie, the latter of whom was watching with glee as Hothoof and Night Light began tending to Posey. Their lips latched to her turgid nipples, still leaking from their earlier hands-on session, but now were freely spurting their creamy contents down their gullets. Even if it wasn’t laden with bimbo magic, the mere act seemed to sexually charge the two married men even further as their cocks swelled even bigger. Even if she couldn’t see it, the stiff protrusions were rubbing against both her inner thighs and allowing her to feel just how eager they were.

Without even realizing it, Posey’s body started moving on its own in her fully realized carnal hunger. She pushed the two men up as she stood and, without skipping a beat, simultaneously shoved her tongue down Night Light’s throat while grinding her ample rear into Hothoof’s groin. The angle of her voluptuous body allowed her to hotdog one rigid dick while slipping the other between her enormous tits, conveying her need to be fucked without a shred of her former reluctance.

The two men quickly got into the spirit of things by grabbing each end of Posey and thrusting their hips, savoring the immensely soft pair of globes they were occupied with. While her lower back was quickly being pasted with Hothoof’s precum as his throbbing rod was squeezed tight by her plump buttcheeks, her plush lips and titanic tits were busy actively sucking and milking Night Light’s own frothing length.

Cookie, who by this point had a manicured hand pumping in and out of her snatch as she was watching Posey be double teamed, couldn’t wait for her turn anymore. She politely tapped Night Light on her shoulder, and subjected him to the same eager tongue-kiss that Posey had planted on him when he turned his head in her direction. He knew what this meant as he felt the 40s MILF rub her pudgy and well-endowed body against his own simultaneously, and reluctantly freed his dick from Posey’s loving clutches while Hothoof was preparing to properly fuck the milk-laden housewife.

Having abruptly been deprived of one slab of pulsing manmeat, Posey would have protested if she hadn’t felt Hothoof beginning to penetrate her now sopping wetness with his own throbbing meatpole. Having jammed it between her legs to immediately reach her dripping honeypot, she could only shudder as she got on her hands and knees, feeling inch after inch enter her with a bit lip.

As she was also bending over, Cookie couldn’t help but smirk after getting a good look at Posey’s madly blushing face as Night Light got into position behind her, and the latter took a few gropes of her large ass before aligning his hips. The 40s housewife joined Posey in moaning aloud as her own damp cunny was penetrated, albeit with more haste due to her partner’s eagerness to experience her fat ass. The telltale signs of sex were already heard in the background, but now the happily married four were fervently adding to the already diverse cacaophony of sounds with the already frantic smacking of flesh on flesh.

From the sheer power of his thrusts, Hothoof could even feel the sheer heft of Posey’s enormous breasts from behind her, feeling the massive mounds swing their huge heft to and fro under the busty bimbo MILF. Contrasting Windy’s evenly endowed body, every body-jostling impact from each collision of their hips would send those large udders swaying in an eye glueing-ly perpetual motion. He couldn’t help but give a grope or two of the milk-engorged mounds, and the wet splat that followed graced his ears along with the sound of his partner moaning aloud.

As for Night Light, he couldn’t get his mind off of the very noticeable difference between Velvet’s slim hourglass figure and Cookie’s thick and deliciously pudgy form as he hungrily pounded away at the latter’s fat ass. The 40s MILF possessed meaty beanbag-sized buttcheeks that seemed to constantly absorb most of the shock from his own powerful thrusts like two oversized speedbags, giving a mesmerizingly gelatinous ripple each time their sweaty flesh impacted and sent her hefty tits into more of a gentle sway below her.

While the two himbo DILFs were occupied with fucking their respective MILF senseless, a being-fucked-silly Posey could make out her husband teaming up with Hondo Flanks and Igneous Rock to take on Cloudy, Windy, and Velvet at the same time, seeing that Cirrus’ mouth and cock were occupied with two women at once. A sense of pride welled inside her as her normally equally meek husband was expertly pleasuring two of the other wives with a passionate vigor. Cloudy looked ready to scream with Posey’s husband eating her out, while Windy looked like she was having the time of her life frantically riding his turgid pillar.

Meanwhile, Posey could also see that Velvet was on her own back while Igneous fucked her face and Hondo was thrusting balls deep into her dripping wet pussy. The fact that she had her slender legs wrapped deceptively tight around the latter’s burly waist, while her manicured fingers were digging into the former’s hips in an attempt to add more force to his pumping motions showed just how intent she was on draining both their bloated balls dry.

Posey’s barely maintained attention to the background was brought back to the group of four when she could feel Hothoof’s thrusts grow more erratic, on top of the volume of precum in her belly increasing more rapidly. Her partner was close, and so was Night Light by the hurried look on his face as he gripped Cookie with an almost desperate hold. Right now, it wouldn’t be much longer to see who would blow their load first.

Judging by Cookie’s sudden cry of pleasure, as well as the sudden loud splat from under her and a grunting Night Light, the latter had reached it first. Mere seconds after this, Hothoof ground his pelvis into Posey, who only had a moment to brace herself before the sputter and spray of his hot seed had flooded her own tight breeding hole. The two MILFS moaned in unison as their respective studs filled them to the brim, partially unaware of the others experiencing their own joint orgasm.

In fact, the timing made it almost seem like it had set off a chain reaction and a cacophony of strained grunts, higher-pitched moans and spurts as each participant in the orgy hit their peak. Various orgasms took place, tight orifices were fully creampied, and carnal satisfaction was experienced by all present. And then, just as it had began, it had ceased with the sound of heavy, labored breathing filling the room along with the sauna’s steam and the smell of sweat and sex.

Posey could barely steady herself long enough to sit on a nearby bench, as well as Cookie and their two boytoys. The two MILFs were seated right next to each other, heavily sweating bodies pressed enticingly into one another while Hothoof and Night Light had an arm wrapped around their respective partner’s torso. While the others saw fit to continue, the four were content with watching at the moment, partly to give Posey some time to breathe.

Cookie: "See Posey, we knew you and Cirrus would fit right in!"

Still trying to catch her breath, Posey merely nodded.

Cookie: "And we still have a while in here. You feel like trying anything new?"

Cookie leaned closely into Posey’s blushing face as she pulled out a sizable bottle of clear liquid, easily detecting the throbs given off by their male partners when they both realized saw what it was, and what was going to follow.

Unhesitatingly, Posey pulled the 40s MILF atop of her lap for a make out session while the latter wordlessly passed the bottle of lube to Night Light. He and Hothoof looked on with eager grins as the two busty mothers smushed their plump lips together, now fully erect again from the erotic show.

Posey didn’t know where she pulled that bottle of lube from, but a similar, albeit more mild chest-thumping mix of anxiety as well as powerful arousal returned as she and Cookie kissed.

Only this time, it came from just how soon she could try it when one of their partners using it on her "backdoor entrance".
