Anna joins Billy in the shower

Anna approached the door that stood between her and Billy.

He had already stripped down and stepped into the shower. Now, in a daze, he stood under the hot water, trying to come back to himself and figure out what the hell had happened to him. Where had everything fallen apart?

For a few minutes, Anna leaned against the door with a smirk, listening in to the sounds of the running water as her older brother slowly washed his strong body. Rubbing body wash across his broad chest, his defined abs, his rounded shoulder muscles…

Water trickled down his strong back and his powerful front, droplets rolling between his abs and ending up dripping from his dangling cock. Anna had intended to surprise him when he came out of the shower - but, after a few minutes of listening to his low moaning in there, she just couldn’t help herself.

Nerdy little heart pitter-pattering in her chest, Anna steeled herself and pushed through the door. Billy immediately turned his head at the sound to see his sister standing there in the doorway, confidently, taking in the amazing sight of his glistening, tall, athletic body.

“A-Anna? What are yooouuuuu…”

Billy trailed off dumbly as, right before his eyes, Anna stripped naked. Nervous as can be, but with her mind made up. And when Anna had her mind set on something, she always accomplished it.

Her ample breasts shifted as she took off her modest shirt, and let it fall to the bathroom floor. Then she began wiggling the hem of her skirt over her fat ass. All the while she was trying to suppress her nervousness by avoiding looking directly at Billy - as Anna finally removed the last of her clothing and willed herself to look up and see Billy’s reaction.

Billy stood in the shower, glistening, and stared at her in a trance. Her body had completely silenced him.

Anna giggled, blushing and retracting slightly with embarrassment at his reaction. Her big brother’s eyes were locked to her soft, full chest. She’d never gotten naked in front of someone before, and all his staring was getting a bit much for the introverted nerd…

Still, his dazed face made it somewhat more bearable. Another sign of her control. He wasn’t stating at her body lecherously, he was being hypnotized by it - an important distinction that allowed Anna some room for assertiveness, and self-assuredness. So she pushed through the feeling, and stepped forward.

Heart pounding faster, Anna pushed through the glass door of the shower with a shaky hand and stood before him. Her naked body was just inches away from Billy’s as the hot water rained down on both of them now. She could hardly contain her embarrassment. She was literally taking a shower with him. Her eyes flicked down at the massive penis between his legs - the first she’d ever seen in real life - and she was intimidated.

“Guuuhhhh… A-Anna? Y-Yuh-You’re… I’m… I’m already using the shower…”

His unsteady speech and hypnotized expression helped Anna relax. Smiling, she held him by the shoulders and guided him into turning around. He followed along with her directions mindlessly, turning his head backwards for as long as he could to keep her surprisingly well-formed boobs in his view.

Shit… Had she always been so stacked? She was supposed to be a nerd… Why was she kinda hot?

Once he was turned around, Anna quickly pressed herself up against his back. Billy let out a soft moan as her breasts squished into his strong muscles, and her hands came around to clutch his chest. Anna breathed, calming herself down. It was less embarrassing for her from this side, when he wasn’t staring at her.

“I know, Billy,” Anna purred, heat building up inside her belly. “But… I wanted to help you out.”

“Wha…?”

Smiling, Anna took some liquid soap into her hands, and began to use it - running her hands across him, soaping up his mighty chest and abs into a gleaming, slightly-foamed delight. Next she began massaging his shoulders with the liquid soap, then his back, then his chest again. Her pussy tingled as she rubbed over his whole body, slicking him up, while she pressed her nude self against him.

“Ohhhhh-…~” Billy moaned, relaxing under her hands. His cock was steadily rising under the hot water, coming to attention at the feeling of his sister’s soapy hands rubbing all over him.

Anna noticed this, of course. Feeling brave, she reached down and gave it a little flick. Liking the way it bounced, she took its length into one shaking hand and gave it a squeeze, eliciting another moan from big bro.

Billy’s dick was so big… Was this normal for guys? She couldn’t even fit it in both hands…

She gave it a few more tepid strokes before her nerves got the better of her, and she quickly pulled her hands away with a small laugh. Exhilarated at her own bravery, she returned to slicking her big brother up, rubbing his chest, squeezing his shoulders, massaging his neck… He was like putty. He didn’t fight back at all. Anna’s confidence was growing, and soon, she found herself loving the pleasured noises he was making in response to her massaging hands.

Relieved at how this was going, Anna giggled, and moved her fingertips up to his chin. Once there, she began rubbing in small circles, first with her fingers all together, and then with them all spread out wide, giving Billy’s chin a slow massage. Paying her respects to the champ.

This chin. This fucking chin. This was the chin that lost. The chin that got Billy knocked out. The chin that gave in. The infamous, legendary, unbreakable chin that got beaten by a nerd.

Anna continued massaging her fingertips into it, now grinding against his back, and reliving the memories. All the fond, pleasant memories she had with her older brother’s chin.

She remembered the way he had bragged and boasted about being undefeated, and “unknockoutable”.

She remembered that first fearful match, and that first fateful uppercut. That had shut him up. A perfect, unexpected present for her return from France - seeing Billy’s eyes roll up in his skull for the first time ever. Losing to a nerd punch.

She remembered the time she took him down, bareknuckle on the couch, and left him spread-eagled and snoozing there. Defeated. Some champ he had looked like then.

She remembered the first time he had briefly woken up during one of her nightly visits - only to get put right back to sleep by her desperation punches. He took so many hits before his body finally gave in…

She remembered the first time one of her punches had instakilled him. The way he had just… Stopped.

God, she would always remember the time she saw him get outboxed and oneshot by their fucking mom…

Anna moaned, her wet, tingly pussy lips dragging on the back of his leg. She bit her lip and closed her eyes, sliding faster. Rubbing her repressed, excited pussy and sensitive nipples against her older brother’s strong body. Grinding, dragging along him.

The excitement was making her lean harder into his back, at the same time putting more **** behind her massaging fingers, pressing into his chin appreciatively and dominantly. That was when something magical happened.

He yawned.

He actually fucking yawned.

Anna suddenly stopped, face red and hot, and laughed. Laughed at the meek sound, and the feeling of his jaw slowly opening in her fingers.

“What the fuck was THAT, Billy?” she giggled, pulled from her fantasies and memories back into the present.

“G-Getting… Tired…” was Billy’s only reply. A devious spark of delight flashed across Anna’s eyes at his admission.

“Oh~? Is that so~?” Anna mused.

With that, she unpaused her efforts and redoubled them, leaning against his back with more **** and pushing her fingertips against him with a deep, relaxing pressure, massaging his chin. Dragging her wet pussy lips across the back of his leg even more hastily. Billy groaned.

She wanted to see how far she could take this. She had stepped into the shower with big bro, and now…?

As her fingers massaged his chin, and she leaned her weight against his back, she could feel it. Billy was giving into the forces put upon him, slowly slumping over forwards. Anna grinned.

“Dear oh dear… Just how sensitive ARE you, Billy?” she asked, moving her hands and massaging the top of his head with her fingertips when his chin ducked out of reach.

Billy only moaned. With some effort, she was able to redirect his slumping backwards, towards her, and Billy began slowly sliding down her body. Lower and lower. Anna felt a shudder of pleasure as his body ran along her pussy on the way down.

“Ohhh…”

Still, she massaged her fingertips onto the top of his head without pause. Down he went, sliding along his sister’s excited body all the way. Big bro was just her pleasure toy as he slowly went lower, and lower, and lower. Eventually his butt made contact with the floor of the shower and his descent stopped with a weak moan.

Billy sat there, dozy as can be, while Anna kept all ten fingers gently giving the top of his head a relaxing massage. It was like the relaxation of it was seeping down into his brain, nullifying it, and leaving her scary older brother woozy and glassy-eyed, mouth hanging open as he stared dreamily at nothing in particular.

“Where are you going…~?” Anna teased, with a confident smirk.

“I’m… S-So sleepy…”

“Oh ARE you…?” Anna said, now bending her legs as she followed him down. Billy let out a low moan as her relaxing, massaging fingers gave him no quarter.

Eventually Anna’s butt reached the shower floor too, sitting behind him. Her first course of action was to reach out with her legs, and wrap them tightly around his waist, trapping him. Billy only moaned and wobbled, nearly falling to one side, as Anna continued massaging his head.

Once confident in her position, her dripping pussy pressed tight against his back and her legs wrapped tight around his waist, she removed her fingers from the top of his head and gave him a moment’s reprieve. Then, after a brief pause, she quickly reached out around his neck, pressed her fingertips to his chin again, and began massaging him there.

The attack’s effect on him was obvious and immediate. Trapped in place, all he could do was let out a low moan as he jaw fell open lazily, and he weakly wobbled from side to side. As if some part of him knew that he should still fight this.

There was a big grin on Anna’s face as he grew weaker, more sluggish. She could actually feel the energy draining out from his chin into her fingertips as the hot water rained down on them. She could hear him slowing down.

“Seriously? Ugh. Weak, bro.” Anna mocked, unable to hide her smile.

Her pussy was so fucking slick. She never expected how much she would get off on nerd power. How excited she’d get, watching big bro Billy fall. Making big bro Billy fall.

“D-Duh-Ddduuuuuhhhhhh…” Billy let out one final groan.

His eyelids flickered and his jaw hung open. His strong arms dangled limply outside of Anna’s tight leg trap. The water droplets came down on him even as he moaned in her grasp. Lights dimming… Then lights out.

His groan fell silent. All at once, he went limp in Anna’s hold. His head hung down uselessly, bobbing in front of his strong, muscular, glistening chest.

Anna breathed in a shaky, excited breath. Her pussy twitched against his back.

“You’re literally sleeping…”

Gulping and containing herself, Anna leaned in close to his ear. Just beyond her lips, Billy’s passed-out head was dangling limply. Her bottom lip scraped against his earlobe and she gasped.

“I just put you to sleep…” she whispered. The words passed through his ear, which tingled with the sensation of her breath, and resonated somewhere deep within the proud boxer’s brain. But he was powerless to fight back, or deny it.

He was knocked out.

Anna was shaking, in awe. This was the best. This was the greatest feeling. Her big brother was a weakling, and it was all thanks to her. She reached around his slumped body, and gave his thick cock one last squeeze. Holding it in her hand. Reminding it who the boss was. Reminding it who had just finished off its dormant, slumbering master. Reminding it who could… Could take that dick for herself any time she wanted. W-When she was ready for something that big, anyway…

Collecting herself, Anna took in a deep breath, then stood up.

“Loser,” she smirked.

The naked nerd reached out with one hand and turned off the showerhead. The rain of hot water came to a stop, leaving the room in total, shocking silence.

Anna’s body was shining and wet. Her pussy throbbing with need. As she stood, she looked down at Billy, slumped there.

The boxing champion. **** with his cock out. Naked, wet, and dreaming. Assassinated again.

Anna smirked.

She snapped a pic on her phone, to preserve the scene forever. Billy sitting hunched over on the shower floor, his naked cock pulsing, useless muscles glistening.

What a fucking loser. Big bro just got put to sleep by a deep-pressure chin massage. He couldn’t even take that much.

His weak ass got knocked out.

“God, Billy… You suuuuuccckk~~” Anna smiled, her words preserved forever as she got a quick multi-angle video of the scene to cap off her photo collection, before stashing her phone with her clothes again.

She stared at him for a long time. His broad, strong chest rising and falling with slow, steady breaths. Anna shook her head, smirking.

“Moron.”

With that, she picked up her clothes, turned, and left the big bad boxer sleeping on the floor of the shower. Done in by his little sister’s dainty fingers. Those same dainty fingers had another job ahead of them, now - satisfying her overstimulated, needy, gushing pussy.

Sealing big bro’s fate was hot enough. But seeing the energy just drain out of him like that… Seeing his big cock exposed and throbbing even as he got put to sleep, seeing all of his powerful, trained muscles in all their glory, go fucking limp… Holy shit. That was something else.

This was the champion that his club all feared. What a joke. He wasn’t anything special.
