Billy is getting weaker

Anna’s indulgent knockouts were having a profound effect on both her and Billy. Being able to punch out a boxing champion every night was doing wonders for her self confidence. It was almost as if all of his past rude actions and his old superiority complex were ancient history. Water under the bridge. Not forgotten enough for Anna to lay off the headshots, but enough that she never felt intimidated or in Billy’s shadow anymore, even when he was awake and not slumbering beneath her pinning legs. In fact, she felt quite the opposite.

She looked at her older brother, the big strong athlete with a promising future in combat sports, and saw someone to be pitied. Someone pathetic. Someone who snored in his sleep. It was all she could do not to laugh out loud when he groggily shuffled out of his bedroom door late into each morning, wiping drool from his lips.

“Heyyy bro~~” she smirked as he moved past her. “How are you feeling~? You don’t look so good…”

“Uuhhhnnn… Sore jaw…” Billy murmured back.

That was enough to get Anna’s little heart fluttering. She might just have to finger herself to an mind-bending orgasm later, thanks to that simple response from a so-called boxing champ. Or maybe she would wait until tonight’s knockout for that.

There was something else too. Anna couldn’t help but notice that, with each passing night, Billy seemed to be getting stupider and stupider. More forgetful. Sometimes he would just totally space out, and stare at nothing with glazed eyes for a solid few minutes. She just took it as another badge of honor. Another sign of her recent dominance over him. Her mother, in a way, did as well.

Heather noticed her eldest son acting differently pretty early on. All of a sudden he was quiet, and sluggish. His completely different demeanor was distracting enough that she didn’t even notice the new positive way Anna was acting, walking around with her head held high and casually doing whatever she wanted - a far cry from her previous shyness.

Heather was worried. Something was clearly wrong with Billy. And the longer it went on, the more one particular thought worked it’s way into her brain. One particular event which may be the cause of her son’s deterioration. After a few days, the gorgeous milf pulled her son aside to speak with him about it. This was later in the evening, when Billy was at his most lucid, and even then he was still so totally off from his usual self.

“What’s gotten into you lately, honey?” Heather asked him, worry in her voice. She bit her lip in concern and batted her eyes, before she continued cautiously. “It wasn’t… the times I knocked you out, was it?”

Billy breathed in a shudder, cock starting to slowly rise to attention.

“N-No, mom, those were ages ago… I think I’m just feeling tired lately…” Billy stammered out, trying not to stare at his mother’s deep cleavage. Heather cocked an eyebrow and leaned forward, hefty breasts shifting.

“Are you sure? I got you pretty good…”

“I’m sure…”

“I mean, you really just dropped like a sack of potatoes both times. It was almost pathetic. And then little Anna somehow got you sleeping mid-fight too…”

“I’m sure!”

Heather pouted contemplatively, crossing her arms beneath her heavy boobs in a way that lifted them up to Billy’s face. “I’d never even seen you beaten before, and then you get punched limp in a sparring match? By your mother? I mean really, knocked completely ****? You were asleep! Your own mother put you to sleep! Hell, Billy, I did it to you twice. I beat you two times.”

Heather paused to let the words sink in for her boxing champ son. She thought back to those matches when she’d outboxed Billy, so soon after he taught her the very basics of the sport. How, in the first, a single punch to the chin had flattened him. How just days later, he had angrily demanded a rematch with his newbie mother - only to get finished just as fast. Outboxed by a superior fighter until he was on the floor sleeping. Heather lifted her tits a bit higher subconsciously as she tightened her crossed arms’ grip at the fond memory. Then she continued.

“And then I did it again, Billy. That night after Aunt Judy came by, when you were sulking in bed and I knocked you out again. I mean, come on, two punches and you were out like a light, just like that? I would understand if…”

“MOM!” Billy interrupted with the most energetic display he’d shown in days. Heather scowled.

“All I’m saying is that I’m worried about you, Billy.” she scolded. “If getting knocked out by your mom, three times mind you, weakened you so much that even your little sister was able to put you down and out as well, then I may have done more damage than we thought. Maybe I just don’t know my own strength. And now you’re acting so defeated and sluggish all the time, I…”

Heather pursed her lips, and the look of worry came back. She leaned in close to her boxing champ son’s ear.

“I mean, Billy, what if…” she lowered her voice to a whisper. Billy could feel her hot breath on his earlobe, sending tingles down his neck, through his body, and all the way to the tip of his cock. “What if I ended your career with those sparring knockouts?”

Billy gulped. Heather leaned in slightly closer, continuing in that same spine-chilling whisper. Like she was sharing an ancient secret from between those gorgeous lips.

“What if boxing your mom was the worst mistake of your life? I would feel dreadful if I somehow…”

“I… I have to go…” Billy stammered out, cock beating like a drum in his boxers. His mouth was dry. Having his mother leaning over him like this and whispering into his ear was getting him too excited to stick around. Another whispered word might have had him creaming his briefs.

Without another word, Heather leaned back and watched Billy run up the stairs, tail tucked between his legs. Hmmm… Something definitely wasn’t right with that boy.

Had she done that?

As the nights went on, Anna continued gently waking and then punching out Billy. Each time, he seemed to go out faster. Was she wearing down his toughness? Or was she getting better? Maybe by the end of this, the timid bookworm would be able to put anybody out cold in a couple of hits. Then again, it could be that she was just becoming more familiar with how to take down club champion Billy specifically. Finding the points on his chin that switched him off the fastest. The angles best suited to knock his head around. The best timings between combo-punches so that he couldn’t recover or fight back. All of this practise could have made her into a specialized Billy-killer.

Over time, Anna worked him down to six punches, then five, then three… Eventually she was reliably KO’ing him in just two shots, with the occasional one-and-done mixed in there too. It was breathtaking. Waking him up, just to see him go down so quickly. One, and two, and out. Back to sleep in seconds. She’d done this to him. It was her. Anna. She’d made him this way.

“Alright, Billy… Wakey wakey… It’s time to count you out again…” Anna smirked, gently shaking her big bro awake.

“Uuuhhhhnnn… A-Anna? I’m trying to sl-“

BAM!

Anna’s small female fist landed flush on Billy’s chin, instantly shutting him up and shutting him off as his head was knocked over to one side. He was cut off mid-sentence, and before Anna could even pull her hand back, he was already motionless with his eyes rolled up in his head. Still, and silent. Back to sleep just like he wanted.

“ANOTHER ONESHOT!” Anna laughed in Billy’s sleeping face. “Ahahahah! Insta-kill!”

She fucking loved when it only took one. It made her feel so powerful. It was fun and all making him see stars and watching him struggle beneath her, all confused, as she pounded him into unconsciousness with a relentless combo, but there was something special about getting it done in one. One bareknuckle nerd fist being all it took to take down the mighty boxer. The big, athletic giant being undone with one dainty punch to the chin.

There was something extra special that night about the way he just… Wilted. He never put up much of a fight anymore, and it was easy as cake to knock him out, but that oneshot had made him look especially pathetic. Maybe it was the way he just shut off. In an instant, he went from asking little sis a question, to being totally unresponsive and out cold. Whatever the case, the shockingly bad performance turned Anna on, and inspired her to break from routine and wake him up again to rub it in. Call it a post-fight interview.

“Heyyy, Billy~…” Anna whispered as she coaxed him back awake over several minutes, gently rocking his limp, drooling body. He was deep under, and bringing him back was a lot of work, but eventually…

“Wh-What…? Anna…?” Billy groaned, groggy. Anna smirked down at her drowsy big brother between her legs.

“What do you have to say for yourself, hmm~? You just got one-punch KO’d by a total newbie. Anything you want to tell your fans after your most recent loss?”

“I… I… What…?”

“Some champ you turned out to be.” Anna giggled. “You don’t even know where you are right now, huh?”

“I’m… I, uuuhhh…” Billy slowly shook his head. “A-Anna, you’re… Sitting on me…”

“Fuck. This is a sad interview,” Anna laughed. “You’re so fucking done. I could probably knock you out cold with a slap now,” she joked.

Anna was shocked when she punctuated her point with a slap to his cheek, and found out that she was right. His head was knocked to one side, and that was that. Just like that, without even a grunt, Billy was asleep again. Motionless and silent, eyes rolled up. No big fight, no comeback, nothing. Just instantly shut down. One smack, game over. Anna’s eyes went wide as a huge grin took to her face.

“Ahahah! What!!?” she shouted. “All I did was slap you!”

She grabbed him by the face in one hand, squishing his cheeks, to get a better look at his rolled-up eyes. It was a sad sight for the strong athlete, his nerdy sis holding his sleeping face so dominantly. It was pathetic, frankly. The former champion of the house had fallen so far.

“You’re out cold! Holy shit! Out. Cold!” Anna exclaimed with joy and disbelief.

Knocked out by a slap. He was done. His time as a great fighter was over. His promising future as a boxer was all gone, drained drop by drop every night by his little sister until there was nothing left. No toughness, no pride, no future.

And now he was sleeping again. Drooling from between his smushed-cheek lips as Anna sat on top of him, slowly grinding her hips backwards and forwards to stimulate her pussy on his pecs. He passed out during the post-fight interview. The reporter slapped him and he went out cold instantly. Some champ he was. Some strong boxer. Some older brother.

Big bro got weak. He used to be so tough, so arrogant. Cocky, strong, and successful. But she’d weakened him. She’d turned him fragile. Steadily, little sis had made big scary boxing champ Billy into her slap bitch. She’d made him into nothing more than a nerdy schoolgirl’s confidence battery. It was a joke how far she had made him fall. Happy birthday, bro. I got you a glass jaw.
