Make it clear who the “little” sibling is

Liz spent her whole life till now in the shadow of her older brother. If she wanted to take a step out the house, her parents **** him to follow. If she wanted to do anything in the house, he was **** to help. Even as an adult she couldn’t get away from him. Her mother always told her to “mind your older brother,” and “don’t be afraid to rely on him, he’s here for you,” well, now it’s time for a change in the stepping order.

She grabbed Josh and slammed him into the wall, nearly knocking over his bookcase. Josh grabs her arm, trying to make her let go. He squeezes and pushes as hard as he can, which Liz finds absolutely pathetic. His fingers can’t even make a dent in Liz’s muscles. She leans in close, her face is inches away from his.

“Alright, Josh.” She says as Josh struggles under her ironclad grip. Her cock curled up and reached his chest, drenching his shirt with cum. “Let me make this clear! I’m not your little sister anymore! You’re gonna call me ‘big sister’ now, and you better mind my words. You better follow my orders, or else...” Josh vigorously nodded, satisfying his big sister. Now Liz needed to test her little brother’s obedience. She set him down and backed up, giving him the space to do what she asked of him next.

“Alrighty Joshie, your big sister needs to test your obedience.” She sticks out a finger, pointing it to the ground and twirling it around. “I’m gonna need you to turn around and put your hands on the wall.”

Josh swallows, his stomach turns as he thinks about what his sister has planned for him. He turns around and puts his hands on the wall. He turned his head around and asked “Is that good?”

“Face the wall and stay quiet! Don’t speak until I speak to you!” Josh whipped his head back around to face the wall, his mouth zipped shut. His lips quivered as he felt Liz put her hands on his waist. “Stick your butt out a little more.”

“W-wha-“

“JOSH! Keep your mouth shut and do what I tell you!” Josh clamps his mouth shut and sticks out his ass more. “More,” Josh again pushes his ass out for his big sister, hoping it was enough. She clicked her tongue. Then, she suddenly yanked his hips towards her own, her rock-hard cock now lying on top of Josh’s ass. A large stream of precum flowed from her cock, soaking his jeans

She wraps her arms around his waist, leaning down and taunts him, whispering in his ear “Even with this jeans on, I can tell you’ve got a nice ass..” She squeezes it and continues “You shouldn’t be so scared, so ashamed to show it off,” she sighs, Josh can feel her breath on her neck as her arms tightens on his waist. He wants to fight, to throw her arms off him and tell her she has no right to treat anyone like this, and that this is wrong. Everything she did to him and his girlfriend is wrong, and she should try to do better than this!

He turns around and locked eyes with Liz, trying to find his voice. But once Liz fixed her hard gaze on him, he knew there was no hope. He no longer saw his young sister’s kind, sorrowful eyes. Instead, he saw a monster, someone so high on their power trip no one could bring them down. Especially with her level of strength, which she showed by grabbing him by the back of the head and forcibly turning it back and slamming it into the wall. Now with his face smushed against the wall, Josh relented. He just closed his eyes and submitted to his big sister, accepting whatever punishment she has planned for him.

Liz ground his face into the wall, only stopping when she hears the wall cracking. Liz still wants to make sure Josh is entirely submissive to her. She turns his face to the side, ready to yell in face about what she’ll do to him now that he’s disobeyed her. Then she sees the damage she done. She sees his bruised up face, his puffy cheeks and eyes. She can see his eye turning purple and his lips split open with blood dripping out. She felt something when she looked upon his broken face, not pride, but guilt. What she's done to him and his girlfriend wasn't right, her brother was just trying to take care of her, and Holly was just trying to tell her that. But then she remembers, only a few days ago, before she started her treatment; how her brother just, blew off all her concern! He was so smug about it too, just assuming everything would be alright! No! She shoves this guilt down, turning his head back to the wall. She knows she's right, and that he deserves anything, ANYTHING, she does to him! She furiously started tearing his jeans off, throwing the cum-soaked scraps on the floor!

Josh stayed silent even as Liz tore his underwear and shirt off. This only confirmed to Liz that Josh knew he did wrong, and he knows he deserves anything his big sis does to him. She forces her body against his, both of them standing straight against the wall as Liz raises Josh's body up. There's no space between them, Josh can feel Liz's hard cock on his back, and her hot breath on his ear.

"Say you're sorry."

Josh tries to turn his head back, but she's too close. "W-what?"

"You've done me wrong, you've done me wrong my whole life!" she scream into his ear. "You know it, too. Why else would you submit to me so easily!"

Josh cant believe what she's saying to him. Of course he's silent, she's gonna kill him if he speaks up! He has to hold in his anger and stay quiet before she bashes his face in again. He hears her giggle in his ear then she says "You haven't apologized yet."

He swallows his pride and apologizes. "I'm sorry." He whispers under his breath.

Liz clicks her tongue, clearly unsatisfied with his enthusiasm.

“Joshie, I can’t hear you…”

He sucks in his teeth and raises his voice. “I’m sorry, I know I haven’t been a good older brother ahh-“

"I know,” she says, cutting him off by sticking two of her fingers in his ass. “You haven't been a good older brother to me.” She takes her fingers out his ass, soothingly rubbing his ass, then sticks three of her fingers in his ass. “Don’t worry, I’m your big sis now, and I’ll show to take care of your little sibling.”

She adds her pinky, then plunges her whole hand into his ass. Josh bites his lips, trying his best not to scream as Liz’s hand stretches his ass. He panting like a dog once Liz takes her hand out.

Liz taunts him, asking “Ooh, does it hurt Joshie?” She shakes her head in mock disappointment, a small chuckle escaping her lips. “A little pain like this, and you’re already struggling to stay on your feet!”

Josh winces when slaps his ass, but still stays quiet. Liz nods in approval, glad to see her little brother knows his place. “Good boy, Joshie!” She screams as puts her hand back into his ass, this time halfway up her forearm. “Don’t worry little bro, this pain is temporary! I’m gonna teach you to like this pain, to crave it!”

Through gritted teeth, Josh breathes heavily. His knees buckle as struggles against the pain. His sister is tearing his ass apart with just her hand, laughing like a madwoman as she does so. He opens his mouth to scream, and instead he moans?

Josh’s eyes go wide when he realizes what he just did. His own body seems to be turning against him now, starting to like the pain she’s inflicting upon him.

Liz cackles like a witch in his ear, amazed that it seems Josh is starting to enjoy what she’s doing to him. She doesn’t really care about his own pleasure, but if he’s starting to like it, well…

She should reward him…
