"C'mon, dear, we've still got some time before your friend gets back," Stellar Flare cooed as she sauntered into her bedroom. She swayed her hips in such a way that her intention was unmistakable. Never mind the fact her tail was off to the side, giving her boy a view of her plump marehood which was moist from estrus induced arousal.
Sunburst immediately went red in the face, pupils shrinking and eyes widening at the sight of his mother's wet loins. Then he quickly regard her tight puffy rump hole with equal fascination. "Coming mom," he called out, his pink and black dappled stiff cock swaying about. As he entered her bedroom, he found his mother already waiting with eagerness. She had propped herself up against the end of the bed, hindlegs supporting her rump with tail to the side. She was looking back at him hungrily, teeth cutely biting into her bottom lip with anticipation.
"Now come on, mommy's been holding her gas in all day and it's starting to get a little uncomfortable,"" she murmured, her doughnut shaped orifice puckering a little before letting out the cutest little squeal as some air escaped. That was all she needed to do to encourage him, he was on her quicker than flies on a pony pie! She felt his warm and wet tongue as it swirled over her pucker and then the tip as it poked and prodded right into the creased cleft. She rewarded him with a long and loud dry fart right into her son's face.
Sunburst didn't hesitate as he shoved his tongue into his mother's tailhole, practically tasting the earthly aroma as it had nowhere to go but right into his slightly gape mouth. With his tongue plunged into his mother's dirty rear hole, it caused the tail end of the fart to fall off into a sputter, ending with his mother letting out an ear pleasing moan of satisfaction. "Nice one, mom... taste just like I remember," he said, then shoved his tongue back into his mother's tight rear.
Stellar Flare smiled at her son's compliment then gasped sharply as his tongue invaded back into her rump hole, "Mhmm, nice to see you inherited your father's appreciation for the finer things in life" She gritted her teeth, squeezed and managed another gaseous eruption that definitely sounded wetter than the one before! "Mhmmph, you really should do something about plugging up my gassy rear, dear," she suggested, forehooves grabbing a pillow and clenching a little of it between her teeth. She knew her boy needed little encouragement when it came to pounding her derriere.
Sunburst welcomed his mother's noxious wind, lapping hungrily as her smelly doughnut as the last bit puffs of air escaped. "This time, mom, I think I totally agree with your plan," he said as he reared up onto his hind legs. Using a hoof, he guided his flared tip till it snugly rested against his mother's wet puffy hole. A sharp jerk was enough to penetrate her orifice, followed by the rest of his modestly thick length as he filled his mother's ass with his shaft.
"O-oh my, what a big stallion you've grown into," Stellar Flare whimpered as her son started to rut her thick mare ass. Each time he slammed back into her, a small wave of pleasure rocked her winking pony pussy and brought her that much closer to an orgasm. "Mhmm, yes, fuck mommy. Fuck mommy right in her tight fat ass," she cried out as she felt her son's powerful thrust rock her body against the bed.
Sunburst grunted with each thrust, balls slapping against his mother's rear as his buried his cock repeatedly into his mother's needy ass. He raised a hoof and then smacked it down over her flank, causing her back to arch as her head reared up and she let out a cry mixed with pleasure and pain. He'd continue to occasionally do this, each time making his mother howl and leaving hoof shaped bruises over her flanks that she'd later have to hide to avoid an explanation. A few more pumps deep into her ass and Sunburst felt his pique reached. He quickly pulled out and watched as spurts of thick gooey hot stallion spunk shot across his mother's bruised and abused ass.
"Mhmmm, yes, cum on mommy's ass. Need to make sure those other stallions know this rump belongs to her strong handsome boy," she giggled meekly, feeling his creamy warm cum dribble down her spanked rump. When he was finished, she was more than happy to clean off his softening cock with her tongue. By the time everything was said, done and cleaned up, both mother and son were tired.
She had just finished deodorizing the air with some sanitizer just as Starlight knocked. Sunburst, his cape disheveled and glasses slightly off center, straightened himself and offered his mom a smile.
"Well, that was good timing," Stellar Flare giggled, giving her son a knowing smile after letting Starlight inside.
"Just a little... I'll get back to you with arrangements for my next visit. Better laid plans," Sunburst laughed, more than a splotch of red tarnishing his orange furred cheeks. He then turned to Starlight Glimmer, "I take it you're ready to go," he asked. He was trying to hide his exhaustion, but it was quite prevalent in his eyes. Though, if Starlight noticed, she didn't immediately say anything about it.
"Oh yeah, got things squared away with dad. I'm planning on visiting him more often" Starlight replied.
"Same with my mother. Though, we should be going. Twilight will want to hear all about this I'm sure," Sunburst replied. Plus, he really wanted to get back to take a nap. It was going to be hard enough to stay awake for the trip home.
Both Starlight and Sunburst gave their farewells to Stellar Flare then proceeded on the journey home. However, as Sunburst followed behind Starlight, he noticed the strangest thing. While normally his eyes didn't wander too often, he couldn't help but notice that his best friend's anus seemed a bit... looser and on closer inspection... a minute, but still noticeable droplet of cum that leaked out then fell into the dirt.
