As she presented her ass to him, Akira couldn't help but lick his lips in anticipation. This was going to be so much better than he ever could have imagined. He positioned himself behind her, his hard cock lining up with her tight entrance. With one swift thrust, he buried himself to the hilt inside her ass, groaning at the incredible feeling of being so deep and filling her completely.

"Fuck..." he panted, beginning to move slowly in and out of her. "So tight... So good..."

Akira growled as he picked up the pace, slamming into her ass with renewed vigor. "Yeah," he grunted between breaths, "You're such a bitch for me... Taking my cock like this..." He reached around and roughly groped one of her breasts, pinching her nipple hard. "And you like it, don't you?"

The sensation of being owned and used by his younger sister was nearly overwhelming, driving him wild with lust.

Her breath hitched in her throat, and then came a long, keening moan as she arched her back off the tile wall behind them, her body tensing and relaxing in waves of pleasure. Her fingers dug into his shoulders, her nails leaving crescents of pain behind in his skin as he felt her pussy clamp down around his fingers.

"Fuck... Akira..." She groaned, her voice hoarse from the effort of trying to speak through her orgasm. "That was... incredible..."

Akira smiled against her skin as he felt her body relax, his fingers slipping easily out of her slick folds. He stood up slowly, his hands moving to cup her hips as he looked down at her, their chests rising and falling in unison once more. "I'm glad you enjoyed it," he murmured, his voice husky with satisfaction.

Amelia glanced away, her cheeks flushed red. "Well... thanks for the shower." She said awkwardly, trying to pretend like nothing had happened between them.

He knew she'd cave eventually; she had no choice. The thought only made him harden even more beneath his boxers. As he lay there, imagining all the ways he could make her beg for it...the things he could do to her...his hand slipped underneath his shorts and began massaging his cock through the thin fabric of his boxers.

"Fuck yeah," he moaned, closing his eyes as he pumped his fist faster. "

Akira groggily opened his eyes and blinked several times, letting them adjust to the light. His gaze focused slowly on his sister standing over him, looking furious.

"What the hell are you doing in here?" He mumbled sleepily, raising his hands above his head to stretch and yawn. Noticing the angry expression on her face, he sat up straighter and rubbed his eyes. "Oh, hey Lizzy. What's wrong?"

"Well, I thought if I gave you some time to think about it..." Akira trailed off, his cheeks flushing slightly with embarrassment. "I just... really want it, okay? You're the only one around." He looked away uncomfortably, hoping that you wouldn't see through his bluff.

"Please?" he whispered, his voice barely audible over the hum of the refrigerator. "Just this once?"

Don't leave me hanging like this...

Akira stepped back again, giving her some space but not retreating completely. He crossed his arms over his chest, watching her intently. "So, what's it going to be, Amelia? Do we make a deal?" He let the words drip with promise and threat in equal measure.

The more he thought about it, the more he realized how much control he had over her now. It was intoxicating.

Akira sighed heavily and rolled his eyes, unable to hide his frustration. "Fine," he muttered under his breath. "Then you leave me no choice." He pulled out his phone again, this time bringing up a different video. It showed the two of them together in the hot tub the night before; she was completely naked while he'd only been wearing his boxers.

He knew it wasn't as explicit as the other video, but it would still be enough to cause trouble if anyone saw it. "Here,"

Akira wrapped his arms around her and held onto her for a moment, breathing in the scent of her shampoo and feeling the softness of her body against his own. As he hugged her tightly, he couldn't help but wonder if this was just another one of those things that big brothers were supposed to do or if there was something more behind it.

Eventually, she pulled away from him and took a step back, giving him a reassuring smile once again before disappearing down the hallway towards her bedroom.

Akira watched her go with a mixture of confusion and hope in his heart. He wasn't sure what had just happened there or where it left them, but he couldn't help feeling like things might be different between them from now on. Maybe... just maybe she really was starting to see him as more than just her annoying older brother.

With a shrug, Akira turned and headed back towards the living room, unable to shake the feeling that something had changed in their relationship tonight.
