"So, this is your surprise, Sophia?" he asked, his voice thick with lust.
She nodded, a wicked smile curling her lips. "Yes, I've been training my asshole to fit your dick inside. And now... I'm ready. So, enjoy."
Adrian couldn't believe his luck. He reached down and rubbed her pussy with his hands, gathering more of her juices to lubricate his cock. The sight of her swollen clit and glistening folds made his mouth water.
"You sure about this?" he asked, his voice barely above a whisper.
"Absolutely," she replied, her eyes locked onto his. "I want to be first. Since I couldn't be first to have sex with you, I can still be first to have anal virginity taken right? You haven't done this with others, so that makes me first right?"
Adrian could not help but throw a wry smile at his sister's competitvenss. He patted her head and said," Yes, my Sophia is the first. Does it make you feel better now?"
Sophia beamed with a smile and urged him to hurry and claim his surprise gift as she couldn't wait to experience him inside her ass.
With one final stroke of her pussy, he coated his cock in her essence. Then, slowly, he positioned the head of his dick at her asshole. Sophia's breathing hitched as she felt the pressure, her body instinctively tensing.
"Relax, sis," Adrian whispered, his voice soothing. "I promise it'll feel good."
She took a deep breath, trying to calm her nerves. Adrian pressed forward, feeling the resistance of her tight ring.
It was like nothing he had ever experienced before, the tightness nearly unbearable. But he knew she was ready, knew she wanted this as much as he did.
With a slow, steady thrust, he pushed inside. Sophia let out a sharp cry, her hands gripping the bed sheets as he breached her ass. Her eyes started tearing up at the painful sensation.
The sensation was intense, both for him and for her. But as he settled in, she relaxed, her muscles loosening around him.
"Oh God, Adrian..." she moaned, her voice trembling with a mix of pain and pleasure. "That's it... go slow... let me get used to you..."
He nodded, respecting her request. He stayed still, letting her adjust to his size.
Her ass was incredibly tight, the heat radiating off her skin as she squeezed around him. Every inch of him was enveloped in her warmth, making his cock throb with need.
After a few moments, she looked up at him, her eyes filled with desire. "Okay... you can move now..."
Adrian didn't need to be told twice. He pulled back, sliding almost all the way out before thrusting back in.
The sensation was incredible, the tightness of her ass making every movement feel electric. He set a slow, deliberate pace, each thrust sending jolts of pleasure through them both.
Sophia moaned, her voice growing louder with each passing second. "Yes, Adrian... fuck my ass... make me yours..."
Adrian's cock throbbed inside her, the tight grasp of Sophia's ass clenching around him with every shallow thrust. Her body seemed to melt into his, her moans growing louder and more desperate as he picked up the pace. Each thrust drove deeper, the friction igniting a fire within them both.
"Ahhh, Adrian... harder... please!" Sophia begged, her voice breaking with desperation.
Her fingers clawed at the sheets, her breathing ragged as she tried to match his rhythm. "Fuck me, little brother... make my ass yours!"
Adrian growled in response, his muscles tightening as he pushed himself to go faster, harder. The sound of their bodies slapping together filled the room, mingling with Sophia's cries of pleasure.
His hands gripped her hips tightly, guiding her movement as he plunged into her over and over again.
"You like that, huh? My cock in your tight little ass?" he muttered, his voice low and rough.
He could feel the heat radiating from her body, the slick sheen of sweat making their skin slide against each other.
Every inch of him was alive with sensation, the thrill of dominating his sister pushing him closer and closer to his climax.
Sophia whimpered, her head falling back as she surrendered to the overwhelming pleasure.
"Yes... yes, Adrian... I love it... I love feeling you inside me..." Her words were punctuated by sharp intakes of breath, her body trembling with each thrust. "I love you making mess out of me."
Adrian's control was slipping, the intensity of their connection threatening to consume him. He needed to feel more, to push them both further.
With a grunt, he pulled out of her, leaving her gasping for air. Before she could protest, he flipped her onto her back, positioning her legs over his shoulders.
"Adrian... what are you doing?" Sophia asked, her voice shaky with anticipation. Her eyes locked onto his, wide and filled with desire.
He didn't answer, instead lining his cock up with her entrance once more. With one swift motion, he plunged back inside, this time hitting depths he hadn't reached before.
Sophia cried out, her nails digging into his arms as she adjusted to the new angle.
"Fuck... Adrian... that's so deep..." she gasped, her voice barely audible over her own moans. Her body arched off the bed, meeting each thrust with an eagerness that thrilled him.
"Yes... just like that... fuck me harder..."
Her fingers then slid down between her legs, seeking out the source of her unrelenting need. She rubbed her clit furiously, the additional stimulation heightening her lust even further.
Adrian watched her, his eyes dark with lust as he took in the sight of his sister pleasuring herself while he fucked her ass.
The scene was almost too much for him to bear, the combination of power and intimacy driving him further towards his own climax.His thrusts became more erratic as he lost himself in the moment.
His breath came in harsh bursts, his vision narrowing down to the sight of Sophia's flushed face and the way her body moved beneath him.
Every noise she made, every shudder of her body, fueled his desire to keep going, to never stop.
"Sophia... I'm close..." he warned, his voice strained with effort. His movements slowed, each thrust deliberate and controlled as he fought to prolong their pleasure.
Sophia's eyes fluttered closed, her mouth opening in a silent moan as she felt the wave of ecstasy building within her. "Do it... Adrian... fill me up..." she whispered, her voice breaking with emotion. "Make me yours..."
