Billy loses the first mother/son boxing match

Everything was ready. His sweet, unawares mother had been set up with loaded gloves, primed to knock little Billy the fuck out. He’d always thought his mother was hot, and he could barely contain his excitement for the upcoming KO.

He started in a normal boxing stance, which his mother mirrored. Both of them knew that Billy wouldn’t be giving this sparring session his all - his mother was only on about two hours of training. All the same, getting to test her techniques and defensive boxing against him was a good way to cap off the session, and Heather was glowing with happiness that her Billy had asked if she’d be interested to learn some of his sport.

The two danced around the cleared-out living room, exchanging occasional blows. His mother seemed a bit tentative, but she was still clearly having a good time. After a few minutes of light back-and-forth, Billy smiled. He couldn’t wait any longer. Breathing in deep and closing his eyes, he lowered his guard just slightly, just enough for her next punch to break through, and waited.

Spotting an opening, his eager mother sent through a heavy right hook, expecting it to be blocked or dodged like all of the others. Instead, it landed with a heavy CRACK. Billy’s legs wobbled and buckled, and he stumbled around the carpeted floor a few unsteady steps as his shocked mother pulled her fist back and watched her poor son nearly toppled over from the connection of her smack to his jaw.

"Oh! Uhh, sweetie? Are you alright?" his mother asked in a worried voice, stepping back and lowering her gloves slightly as she watched her boxing Billy staggering around.

"y-yuhhuh. k-keep going, mom." Billy just about managed to slur out, raising his gloves up to show his mother that the fight was still on. It wasn’t much of an intimidating sight, with how weak in the knees he was.

"well, alright..." Heather said, chewing her lip. Skipping around on her feet around the punch drunk Billy for just a few seconds, trying to get a good angle just like her taught her, she hesitantly wound back another punch.

SMACK!!

Her second punch clipped him on the chin again, and this was the winning shot. As soon as her glove made contact, Billy’s eyes rolled up and his whole body went limp, dumping him onto the floor. His full-bodied matronly mother had just knocked Billy flat on his ass, and out cold.

"Oopsie! Are you okay, Billy? Billy?" Heather asked with concern in her voice. She hadn’t expected something like this to happen when he asked to train her a week prior.

Billy didn’t stir. He didn’t even make a sound or move, he just lay there. Heather hurriedly pulled off a glove, making her expansive breasts shake from the effort, and rushed to kneel by her poor son’s side. Leaning over his sleeping face, dangling her sports bra cleavage right over him, she frowned. He was really knocked out. She took it in for a few moments, before she worriedly slapped him awake.

"Billy? Billy." a few more slaps. "Wake up, sweetheart."

With a groan, Billy’s eyes fluttered open. He found himself on his back in the middle of his living room, and with his concerned genetically gifted knelt beside him, looking into his eyes with worry, wearing a single boxing glove.

"Are you okay?"

"unghh... y-yeah, mom. what happened?"

"Well, honey, I'm afraid I think I ended up winning on accident..."

Billy's heart leapt at the way his sweet mother's worried face wouldnt look him in the eyes as she admitted to kicking his ass. His eyes flicked down to her heavy dangling cleavage while she wasn’t looking. She was like a goddess... a goddess who knocks out her son...

"Well, I'm alright now. Thanks for checking on me." Billy said, straining to sit up.

"Are you sure? You went really limp... should we send you to a doctor?"

"I'm sure mom, thanks,” Billy said. "Phew... that was different than I expected."

"What do you mean?"

"Being knocked out."

Heather's eyes flicked up to his again, and the room was silent for a moment.

"... that was your FIRST time being knocked out?" Heather asked, with a cautiously excited pride in her tone that told Billy she'd never forget it if she was the first one to ever knock him out. His own mother... his dick lurched.

"Yeah, mom," he said. "That was the first."

His mother’s mouth formed a wide smile. He could tell she was quite happy to hear that. Quite happy indeed. Seemed like momma could still put her teenaged son in his place after all. Some elegant movement to get her fist over his guard, and it was lights out for boxing champ Billy…

"Well..." she said, standing up with her smooth, powerful, matronly thighs, glistening with sweat from the workout. "I think you need to work on your boxing a bit more, sweet pea." she teased.

Billy gulped, eyes glued to the motherly bosom contained by her tight-fitting sports bra. Its deep cleavage, beaded with sweat droplets, shining in the light as she stood over him like a true goddess…

That night, Billy wanked to the memory of what happened. The next morning as well began with the boy furiously masturbating in his bed to the image of him getting cracked on the chin by his own mother, and dropping uselessly to her feet. His hot, sexy mother, knocked him out. The fact that it was real made the orgasms so much better.

When he finally emerged from his room, it still wasn’t over. At breakfast, and as he walked through the house the whole day, his mother kept shooting him little looks. Small nearly-hidden smiles. Her body radiated confidence, and power. He could feel his dick throb in his shorts each time he caught her flicking him a smouldering glance, as if to say she KNOWS she could take him down at any time she wanted. And the comments she made had his heart leaping in time with the pulsing of his cock... she only said a handful, each with several hours between them during which she was back to being her usual warm, loving, almost coddling self, but they were just so uncharacteristically taunting, so unbecoming of her melodious happy voice…

“I guess we don’t need to book another training session, do we Billy?”

“I know you’re feeling a bit beat up, so how about we have your favourite for dinner, hmm? Would that cheer you up?”

“Careful, Billy! You wouldn’t want to bump that slice of pizza into your chin while it’s still healing from me. You might just knock out on the spot~~”

A few times during the day he had to make a hasty retreat to jerk one out to the thought of that arrogant expression, those full boobs hanging over his stunned face…

He’s done it. He’d gotten cleanly knocked the fuck out by his own mom, just two hours into training. And it was like a dream come true.
