She uses him as a human vibrator

Anna brushed the back of her hand across Billy’s cheek. She caressed his face gently, almost lovingly, even as the open-jawed loser’s loud snoring sent vibratory feedback through her hand.

“Wow. You’re super fucking knocked out,” Anna breathed hotly, blushing with just as much heat. “What a joke…”

She took Billy’s face into her hand and turned it side to side, toying with it. Making her fun with the ****, snoring loser while she debated what she should do next.

Anna couldn’t hold back a smile as she got a full sensory demonstration of her big bro’s total submission. Hearing him snore, seeing him make that stupid face, and feeling his limp, unresponsive body… Moving his face side to side, squishing it in her fingers…

She had done this to him. A big, strong, popular boxer… Her brother… Knocked out and snoring. A twitch went through Anna’s pussy at the thought, making her whole body shudder.

She had done this to him… And maybe… She should enjoy it.

Pausing a moment, as if to talk herself out of it, Anna found that she could resist no longer. Slowly, tepidly, Anna lifted herself onto the bed where Billy lay. A vanquished opponent.

She first placed a hand over his mouth, silencing him. Those rhythmic rumbles were muffled, transferred into tingly vibrations across her palm. Breathing heavy, Anna retracted her hand once more. A slight wet sheen coated her palm, from her older brother’s breath.

Anna laughed to herself, trying to ease her nervousness.

“H-Haahah… F-Fucking mouth-breather…”

She gulped, and set her mind straight. She was doing this. No way was she backing out now when she had a golden opportunity like never before. Awkwardly, Anna stripped off her panties one leg at a time and tossed them aside.

Now wearing just a bra and her open lab coat, the long white ends of which lay draped over her calves, Anna walked on her knees along the mattress. She climbed over Billy, getting to a mounted position. Her breathing grew shallow. Anticipatory pleasure ran through her, and she was shuddering as her legs spread - slightly stretching her **** pussy open. The feeling of those lips spreading apart as her legs made space between them was electric.

“Y-You’re nothing… Nothing to be scared of… You’re just a mouth-breather…” Anna panted quietly to herself in reassurance. The rumble of her older brother’s rhythmic, deep, loud snoring still filled the room.

She had knocked him out. She had made him snore. She could do this much…

Anna moved herself up Billy’s body slowly. It was all the shaky, excited, quiet girl could do to move herself at all. Anna eventually managed to position herself just above his face - with her knees on either side of his head, and her pussy just inches above his open, snoring mouth.

She held her breath. Then slowly, ever-so-slowly, she lowered herself down… Down onto Billy’s face, biting her bottom lip in anticipation.

Her lab coat hem floated down to the mattress at either side of Billy’s head as she touched down, obscuring his humiliatingly stupid face from the rest of the room. This view, from above, was Anna’s alone.

As she was touching down, Anna adjusted her pussy to be placed juuuusstt right up against his nose. Something to grind her clit against, while his open lips attached to her lower ones. If the shuddering girl was right, his open mouth would would be like a funnel made to guide all of his deep, vibratory snores right up and inside of her…

But she never could’ve predicted how it would feel.

As soon as she made contact, Anna gasped, her head rolling back to gape in awe at the ceiling. Oh god - it was even better than she’d imagined!

The moment her pussy touched down, Billy’s loud, rumbling snores were quickly silenced. Instead, all of those vibrations were translated straight into her. She was making him snore on her pussy!

Anna moaned, her toes curling as she rolled her head to one side and then the other. This was gooooodd…~ It really was like she had her own human vibrator!

“Fuuuck yes~~”

Anna rolled her head back again, and began riding up and down his face. Dragging her pussy lips across his open mouth, the bridge of his nose… Simultaneously grinding herself to a fantastic climax, while at the same time forcing him to fill her pussy up with more of those wonderful snores. She couldn’t get enough!

Anna squeaked with glee, which slowly turned into another low moan. Almost a purr. She let her eyes close slowly, drinking it in as she slowly grinded her hips back and forth. Taking in everything she could from this defeated boxer’s deep rumbles. Taking everything he had left in that **** athletic body.

“So-called champion…” the nerdy girl muttered through a smirk. “Ooohhhh…”

God, this felt good. It didn’t even end at the physical pleasure of her older brother snoring on her pussy - the mental pleasure of her total domination over this stupid brute was almost just as sweet!

Stabilizing herself on his face for a moment, Anna reached out with one hand to hold his bicep. She rubbed and rolled the muscle in her palm, cooing. Such a big, powerful thing… Fucking useless. Relaxed and soft. Like play dough. She couldn’t even fit the entire muscle into her small, dainty hand, yet still, his powerful arm was as limp as a wet noodle.

Anna closed her eyes again, letting out another deep, purring moan from her smiling lips. She gave his big bicep a nice squeeze, tensing her thighs around his head as the pleasure ran through her.

She was really close now. Just a bit more of those wonderful vibrations right on her clit, and she would start cummi…

Anna’s face scrunched up. The vibrations were getting softer. Opening her eyes, an irritated expression on her face, she looked between her legs to look for an answer from Billy’s half-obscured face.

As she glared at him, the vibrations grew even weaker. His rumbles gradually faded out completely as he came to, groggy but conscious beneath his little sister’s pussy.

“Uhhhnnn…?” Billy managed to groan, his eyes slowly flickering awake.

“Don’t you dare stop!” Anna commanded.

She balled up one hand, and before he even knew what had happened - BAM! Anna slammed a fist into his forehead, communicating her orders directly with his brain.

And it obeyed.

Anna watched as, all at once, the dominos fell again. Billy’s eyes rolled up in his head, then slowly fluttered closed again. “O-Ohhh-hhhh…” was the sound of the weak, wavering moan into her clit as he went out.

The sight and sensation sent a shiver through Anna, and she unballed her fist. Placing the hand back onto his bicep, Anna gave the large, useless muscle another squeeze, and waited. She sat on his face, gasping, and waited in anticipatory silence.

…

Then, slowly, Billy went back to those rumbling, vibrating, regular snores. Anna squeaked as it filled up her pussy once more, like a hunter devouring its prey. She wiggled with pleasure, threw her head back, and moaned the most ungodly, animalistic moan you’ve ever heard.

“Ooauuuhhhhhhhuiiiie~~!!”

That was it - this final show of domination, of her brother’s submission, sent her over the edge to a powerful, overwhelming orgasm.

“Ghn~!”

Anna suddenly doubled over forwards, her thighs tightening against Billy’s head as if to pull it closer and extract even more snores out of it. Her pussy spasmed and her body shook as she began shamelessly cumming on his face.

The repressed nerd’s body was twitching and glitching up a storm. The feeling was so intense that she almost rocked back and forth as she rode the wave. The slight muscles in her thighs were firing off randomly as his unending, deep, powerful snoring rumbles filled her to the brim even as she shook through cumming on his face. The snores of her irritating, cocky older brother guided her pussy all the way through the powerful orgasm until she was left panting, red-faced, and altogether worn out on top of him.

“Guhh…~” Anna grunted stupidly, eyes rolling back in her head briefly.

God, she was spent. Ironically, snoring on her pussy was the closest Billy had come to putting up an actual fight against her. To wearing her down. He came closer to knocking her out as a vibrator than he ever did as a boxer.

As the last of the orgasmic aftershocks died out, Anna found herself completely bent forward, clutching two tight fistfuls of pillow with Billy still snoring his silenced little song into her cunt. Anna sighed, unclenching one hand, and bringing it up to wipe some sweaty hair out of her red face. Slowly catching her breath, but not yet confident enough in her balance to start dismounting from the boxing champion’s face. And besides, those rumbles on her pussy were kinda fuckin’ nice…

Anna had really lost herself for a moment there. Talk about cumming yourself stupid.

Once she was finally ready, Anna slowly lifted herself up on shaky legs, standing above and revealing Billy as he lay back in bed. The moment her pussy left his face, Billy’s loud snoring was free to fill the room, instead of Anna’s kitty. The loud, rhythmic, relaxing noise played in Anna’s ears, no longer obstructed as she stared down at her older brother’s face. Drinking in the view.

He was open-jawed, and gawking. Like his face was stuck in a mask of his shock at the moment of being knocked out. A slight red mark was visible on his forehead, from where Anna’s dainty little nerd fist had done some mid-ride maintenance, and there was a shiny sheen of her girlcum all over his face.

“Pfffft.” Anna couldn’t hold in a small laugh. He looked, and sounded, ridiculous. But she quickly composed herself again, not wanting to get distracted and miss a single detail of this moment.

She studied him, in silence. Committing the sight to memory. Comparing it with how he had acted before she had taken that trip to France. How far he had fallen…

“Zzzzzz…”

Anna stood on the bed, a foot either side of his head, and stared down at the humiliated, defeated boxer. Listening to him snore. After a pause, she simply lifted a foot and placed it on his chest, in a kind of victory pose, her lab coat swishing from the motion.

Billy was fucked. He had utterly lost to his own nerdy sister. What kind of big brother was he supposed to be?

Anna sighed, wiping some remaining strands of sweat-soaked hair out of her face. The memory of Billy as a cocky, celebrated athlete was still present in her mind, even as he snored under her foot. Even after having just harnessed those snores into an explosive orgasm all over his face. He had a reputation, and he was not living up to it one bit. Not living up to his own legend.

He was supposed to be tough. Unbeatable. Big and bad like nobody had ever seen before. Anna couldn’t let him recover yet. She needed to make sure that she could always bring him back to… This… Whenever she so pleased.

“The experiment… Continues…” Anna panted between hot breaths. Then, hopping off the bed, she plucked her discarded panties up from the floor, and staggered on wobbly legs back to her own bedroom. Leaving Billy to sleep this latest defeat off.

Anna sure knew how to slay him. What a stupid fucking mouth-breather.
