Billy's most humiliating KO

"I am still waiting...", Heather reminded her dazed son, swaying her tone naughtily. She was bent over, peeking behind her shoulder, smirking at her son.

"Uh...huh?", Billy droned, drooling stupidly

"You wanted to...apologise...remember?", she continued, playfully wiggling her hips, as if cuing him to continue.

Billy's mind snapped back to present, now completely focused on those soft, sweaty globes. He inched his head towards her left cheek.

"I am sorry mmm...". In his haste, Billy didn't even bother to finish his rumbling. His quivering lips were sealed to his mommy's rump.

Heather chortled as soon as she felt Billy's lips. Such eagerness to please his mommy. Such fear, of getting knocked out by her strong motherly fists.

A surge of pleasure was coursing through her. This power over her son, who was once 'the' champion boxer, was intoxicating. The image of Billy kneeling down, head bent, his lips on her perfect butt, had removed any speck of respect Heather still had for her son.

Oblivious to his mom's thoughts, Billy was just busy 'apologising'. He could taste her sweat and feel her supple skin, all while kissing her juicy bum, leaving a trail of lip prints all over her cheeks. His dick was painfully hard and throbbing. His veiny mushroom head was grazing against his boxers, a caress away from exploding.

Owing to sweat, each kiss was followed by a 'plop' when he plucked his lips from her cheeks.

*smooch*

*plop*

*smooch*

*plop*

Heather had already figured out Billy's obsession the way he was kissing her ass. Billy was clearly using his tongue, practically licking her rump, instead of kissing. A million naughty thoughts were taking over her bimbo brain. She squeezed her eyes shut, bit her lower lip, and attuned her senses to her son's wet lips, her own digits busy with her wet snatch.

"Billy...", Heather almost moaned

"Ye..es...mooommyy?"

"Apologise....hard...er!", she demanded, huskily

Billy's stupefied brain, at first, couldn't process what she just said.

"Uh...h"

Then the realisation hit. Her words came hammering down, jolting his dazed mind. An idiotic grin spread across his face.

He grabbed those cushiony globes and spread them apart, bringing his face closer.

Billy was blasted with a hot and humid air, courtesy of Heather's sweat. Her musk was strong and earthy, which wasn't surprising as she hadn't showered since yesterday. His eyes were trained on her dark puckered hole, just behind that thin, moist strip of her blue thong. Her trimmed, pink pussy lips were wet with arousal.

He pulled her thong strip sideway with his thumb. Heather glanced behind, curiously. Her shiny wrinkled hole twitched, as if inviting him for a smooch. Billy drooled at this sight, breathing in the acidic scent. Unable to hold himself any longer, he went in with his tongue prodding out like a spear.

His tongue finally made contact with her brown, puckered skin.

The mere sensation of something wet touching her anus sent a shiver down Heather's spine. Her eyes snapped open. She clasped her lips shut with her palm to stifle her gasp.

And jolted her ass back, involuntarily, with a bit much energy

Her huge bubble butt smashed right into poor Billy's unguarded face. He was momentarily engulfed between his mommy's massive cheeks, his senses overwhelmed with her musk. His head bounced away from her ass, further rattling his damaged brain.

Billy had just been KO'd...

...by her mom's ass

Heather, unknowingly, had defeated her muscular son, not with gloves, not with her fists.... but with her strong succulent ass. She had somehow made her son dumber, without those loaded gloves. She 'literally' held the power.

Billy's limp body had magically settled on his haunches, with his hands flumped down on the floor. His eyes had rolled back into his head.

Heather, confused as to why Billy had stopped kissing, turned around.

"What happe......BILLY!"

Little did poor Billy know, this ass knockout was going to be a turning point in his life...
