As soon as Ping opened the door, Flan was on top of him.     At dusk, with the last hints of sunset dissapearing over the ridge of houses within this relatively normal suburb, the roobat's vivacious partner had had him anchored on the ground ;chest up, dazed, and shellshocked ; All of his limbs sprawled out as her equine body planted itself right on top of him.  As soon as he gotten back from his errands, she had made her intentions known.   Flan was desperate. Flan was *this* desperate in fact. Despite how she had attempted to ignore the rapid buildup of libido and estrus within her during the week, it had finally toppled over her limit and left her this wild fiend dedicated to sating her lust.   "Te extrañé mucho!!" she gasped aloud with panted, exhausted breath. Sweat droplets drizzled upon the fluffy surface of Ping's pearly-white chest as he rubbed his noggin, with gaze slowly raised up innocently at his overly horny companion.   Before he can even mutter "Heh, well I was thinking of you too" , an inescapable barrage of kisses impacted his face, peppered from forehead to chin and with plenty sent snug right onto his own set of lips. Flan doesn't allow him even a single millisecond to recover as she plants herself upon him. The sensation of her warm underbelly meeting his chest, coupled with the fact that an extraordinarily intense amount of heat was coming off her lower region, was all that Ping needed to understand how badly she had missed him.  His voice continues catch in his throat as he takes it all with eyes slightly winced shut and mouth curled into a wide grin. "Why stop her?" he thought, as he allowed his beige, blushing pony love to get in as many tonguelicks as she could muster , to her heart's content.  With expression a look of half-lidded heaven, Ping waits till Flan tuckers herself out with this sensational greeting, with a tender palm easing her sweaty figure off of his abdomen as soon as she started to pant like an exhausted mutt. She followed him inside , rested against the side of the wall , while he offered a tender liplock to her before deciding to unwind.   Despite how she looked like she had been put through quite the ordeal, the lust within her refused to falter, and only began to stir anew. This powerful second wind of energy flowed its way through Flan's innerworkings as soon as Ping got up and adjusted himself inside , her heartrate quickening as soon an idea had spawned within her pone noggin. While Ping recovered/undressed within their bedroom, adjusting himself inside as he slid himself out of the stuffy clothes he had been trapped in all day, a familiar voice was soon enough ringing through the hallway: "mi amorr~"   Rolled aloud in a way that ensured he was in for something special right outside his room no less. Ping let out a snicker as he began to shimmy his underwear downwards, wondering what on earth she could be planning ,   even as she was bolting towards him. Far faster than Ping was expecting, Flan manages to move quicker than he can even react. A blurr of tawny brown and light coffee was quick to dash up onto the bed, sidestepped around Ping in such a way that he was turning to gaze not upon her, but her after image. This brief moment of confusion put him in a daze long enough to allow Flan to clench her thighs, flex her flank, and send her hips sent skyward. Her tail craned backwards as the dock of her tail was hilted at a 90-degree angle, allow her massive pucker to finally expose itself and and the amount of steam it was generating at this point. Sweat drizzled down her fat hole and her oozing, dripping slit. Her cuntlips looked positively drenched and matted in her own secretions, presented in a way that looked as if she had been fingered with olive oil all over her puffy mare slit. As her fleshy buttocks supplementing her anal tire tensed, after all this time, her rump pucker was finally given what she had been craving as soon as she woke up.  With ass moved in such a way that even Ping couldn't deter her movements, providing him a front row seat to the expertise in which Flan planted her fattened puffer down upon his cock. It slid in with a long *sssssqqssshshh*-ing sound , this reverberating, resonating noise that has Ping shaken to the core. Every second the pleasure only continued to double. Triple even. Inch after inch of her bronzed, puffy , squishy puckermeat suckled down his surging pink rod; Adamantly clenched but still squishy soft at the tip where his cock now rests deep within her fat pone rump. Both of their minds similarly sent adrift in a sea of pleasure , the roobat's clammy palms and rocking hips moved almost all on their own as they readjust themselves upon Flan's ass. His fingers dig so hard into her cheeks that they nearly create trenches, but in this state, Flan was only loving it. His hips began to work themselves just like how she loved. Repeated thrusts were only building in power with each subsequent one. It lurched her forward as she squirmed and rocked her ass right back. The resounding, stimulative pistons were working her hole like the perfect cocksleeve, with bot of their voices becoming hushed and overcome with whimpers. Flan's mouth opened wide, her pupils pointed in different directions, one eye half lidded and the other slightly raised, she was looking quite the part. Ping was overcome with pleasure, almost on the verge of passing out from the way her pucker supplied such SUCTION against his groin, yet he maintained his perseverance just to give her ass a proper loving as is customary for the boundless well of energy that his equine companion once in a blue moon.   It wasn't long before Ping began to feel his own onset of lust take hold. With both of his tangerine-sized balls lowered and swollen with plenty of unmasturbated-seed, and with his surging prick completely buried beneath all the tender, supple meat of Flan's generous asshole, he re-positioned himself. He desired to show her the true extent of his love . Both of his palms guided themselves forward, taking soft squeezes against her sides and underbelly as he truly mounted her rear; Grasp firmly dug into her frame as his hips began to give a repeated series of powerful thrusts. Every single sinewy ounce of muscle was sent rocketed into Flan's asshole through these ballsdeep-and-then-some pistons that sent visible ripples through her body, and even got her voice to break during each one, much like: "hh.Aa!-Aah~"   After just but a handful of these extremely potent thrusts was enough to get Flan squirting hard enough to splatter the floor in her excess juices. Her caramel-colored pussy folds flex and ache, orgasm rippling through her vulva as her hersheys-kisses sized/colored nub vibrated with excitement. Fresh cunt nectar continued to be milked out of her pussy, yet the countless orgasms only encouraged her to tighten the clenched grasp of her asshole around Ping's cock with that much more force. The pounding of his rockhard erection up her rich donut is felt all throughout her body, stimulating the inside of her nethers in such a fashion that it enacted a squirm and  spasm through each flank. The way in which he would drag himself all the way outwards and leave her phat ponebooty so hollow and empty feeling up her hole...and then rapidly follow up with such a ramming blow speared through her ring that it has her stance on the verge of stumbling and collapsing at every battering-ram blow of her roobat's fat cock up her greasy ass. Beads of sweat soaked her face as a sense of lightheadedness overtook her, with her bushy tail sent into a twitching fit as her cunt still spewed her pussyjuice release with no end insight. Ping paused for a moment, with his cock still lodged and locked inside her asshole donut, as he asked "You feeling oka-" But Flan was already liplocking him hard in a passionate liplock. "S...Si~"   With heart elated, and the sight of Flan's messy, drooly, still-horny expression enough to send his nether region ablaze with passion, Ping grabbed hold of Flan's ass even tighter. Once more, Ping began to offer the same all-the-way-in/out thrusts as before, only this time , he doubles the tempo. The repeated reaming and ramming sensations sent lurched within Flan's puffy pony donut have her bouncing up and down in a wild fashion. Her tongue flopped out , her mind goes completely askew. Every single sensory organ within her ass was being stimulated at once as that stiffened prick dug into her harder , and further, than it's ever reached before. His stiff shaft throbs against her gelatin-soft anal walls. The firm, rubbery cockhead dug itself against the upper region of her puckermeat as it wormed its way up her ass ; He worked at her rump like it was a new onahole that deserved a good breaking-in ceremony.  The sounds of her quavery moans mixed in with her slippery donut squishes was like music to Ping's ears. He nuzzled against her face. A wet kiss was sent to those bubblegum-pink cheeks of hers. All of this loving and the sweet nothings he started to pour into those wobbling mare ears conducted at the same time his hips were moving all on their own, and giving her asshole a fucking for the ages. A deep, sensual plowing that had her entire hole emitting bullets of sweat beads upon the glistening surface of her fat seat. Her ass clenched as hard as it could, but at this point, it was like a slack, loosened pool toy that had gone partly deflated, yet Ping still continued to slide into her loose ring. He wanted to ensure she'd enjoy what he felt coming.     "a-aah! " With one last adjustment, Ping took hold of Flan's body, and moved her upwards while (as she was upon the very tip of his cock). Holding her tightly, but not too tightly, at the midsection, and with the spurrs of lust dug deeply within his psyche , Ping shuddered as he drove her downwards. Gravity sent her planted downwards with such speed and force that it has Flan partly mindblanked by after glow. A soft trickle of her femcum could be heard drip dropping onto Ping's chest, as another sound, a noise of "glt-glt-glttttt" emanated fro m Flan's innerworkings. Hot, runny cum poured from Ping's juicy rod as he kept himself ballsdeep up his pony lover. The monumental release of sperm up his meaty totem has him nearly seeing stars, yet the enticing sounds of Flan's voice all throughout his spunkload kept him conscious. Even Ping couldn't help but smile warmly when he felt her start to slightly swell ever so faintly at the gut region, thanks to the load he was bestowing while sufficiently submerged at all sides by her thick anal walls. His jizz acts like warm caulk and his dick like that of a plug, allowing it to pool perfectly within the confines of her tummy as her mind slowly returned to her. Soupy sperm continued to build within her rump as her pussy finished up on the dozenth and final release of femcum. Flan was still gasping for air and unable to catch her breath, she would only be able to blow air-kisses to her love from over her shoulder.By now, she'd have surely lost all ability to move her joints after being stuffed from her one true love in such a way, that only Ping could provide.
