Anton swung open the door to his shared bedroom, a smirk playing on his lips as he took in the sight before him. His younger sister, Olya, was lying on her bed, her legs spread wide and a large anal plug peeking out from between her round cheeks.
"Well, well, well," Anton said, chuckling as he shook his head. "You little minx, what have you been up to now?"
Olya grinned, looking over her shoulder at her brother. "I've been bad, Anton. I need to be punished."
Anton raised an eyebrow, amused by his sister's playful attitude. He walked over to the bed, giving her bottom a firm smack. "You certainly have, you naughty girl."
Olya yelped, her voice sharp as she quickly pulled out the plug. Anton couldn't help but chuckle at her antics.
"You're such a drama queen, Olya," he said, shaking his head.
Ignoring his comment, Olya wiggled her bottom invitingly. Anton took the hint, sliding two fingers into her slick folds and beginning to massage her.
Olya moaned, her body trembling as she pushed back against his fingers. "Oh, Anton...yes, just like that."
Anton continued to pleasure his sister, his fingers moving in a steady rhythm. He could feel her getting closer and closer to the edge.
With a final thrust of his fingers, Olya cried out, her body shaking as she reached her climax. Anton smiled, pleased with himself.
Without wasting any time, Anton quickly shed his pants, revealing his erect length. He positioned himself behind his sister, his tip pressing against her still trembling entrance.
"Ready for your punishment, little sister?" Anton asked, a smirk on his face.
Olya looked back at him, her eyes sparkling with mischief. "Always, big brother."
With one swift thrust, Anton filled his sister's tight channel, causing her to gasp in pleasure.
Anton began to move, his hips pistoning as he took his sister from behind. Olya met him thrust for thrust, her body moving in time with his.
The room was filled with the sounds of their lovemaking, their moans and gasps of pleasure echoing off the walls.
Finally, Anton reached his climax, filling his sister's rear end completely. The two collapsed onto the bed, their bodies spent and satisfied.
As they lay there, panting and sweating, Olya looked up at her brother with a sly smile. "I guess that means I'm a good girl now, right?"
Anton chuckled, shaking his head. "You're always going to be my little minx, Olya. And I'll always be here to give you the punishment you deserve."
