Anton swung open the door to his bedroom, letting out a sigh of relief as he finally escaped the clutches of his overbearing mother. But his moment of peace was quickly shattered when he caught sight of his sister, Olivia, going through his dresser with a mischievous grin on her face.
"Olivia, what the hell are you doing?" he exclaimed, striding over to her and trying to snatch the lacy panties from her grasp.
"I was just looking for some socks," she said, batting his hand away and holding the panties up to her nose with a playful pout. "But I think I found something even better."
Anton rolled his eyes, calling her a "nosy little thing" under his breath. But as he glanced at Olivia's outfit, he couldn't help but let his gaze linger on the thong she was wearing. He gave her a playful smack on the butt, earning a yelp of mock outrage from his sister.
"Nice choice, sis," he said with a smirk.
Olivia stuck her tongue out at him, but couldn't help the blush that crept up her cheeks. She was a grown woman, after all, and didn't need her older brother's approval for her fashion choices.
But as Anton glanced at her butt again, he noticed something else that caught his eye. A large anal plug peeked out from the top of her thong, and he couldn't help the way his eyes widened in surprise.
"You little minx," he said, shaking his head in disbelief. "Have you been experimenting?"
Olivia blushed even harder, admitting that she had indeed been trying out some new things. Anton couldn't help the way his curiosity was piqued, and he teased her mercilessly, calling her a "deviant" and asking her to show him more.
Olivia challenged him to try something new as well, and Anton raised an eyebrow, intrigued by the idea. Before he knew it, he was pulling the plug out of Olivia's ass, making her gasp in surprise.
He started massaging her ass, making her moan with pleasure as he teased her entrance. Olivia started moving her hips, getting into the rhythm of things as Anton grinned and enjoyed the show.
But Anton wasn't content to just watch - he wanted to take things to the next level. He quickly took off his pants, revealing his erection to his sister's wide-eyed gaze.
"Relax, sis," he chuckled, seeing the look of fear on her face. "I'll take it slow."
And he did, slowly entering Olivia's ass and making sure she was comfortable every step of the way. Olivia started to enjoy it, moving her hips in time with Anton's thrusts as he filled her completely.
When they were both finished, Olivia collapsed on the bed, satisfied and content. And as they lay there, panting and smiling at each other, Anton couldn't help but think that maybe having a nosy little sister wasn't so bad after all.
