The siblings

“Hey Brandon, does this bikini make my ass look big?” Madison asked as she directed Brandon’s attention to her. She was standing by the mirror checking herself out in her brand new bikini she bought just for this trip. Brandon looked at her sister with wide eyes, they had done these so many times when they were younger, seeing each other naked and commenting on each other’s bodies. Brandon didn’t like hanging around his sister in public, especially around Ashley, he didn't need to be reminded of his sister's great body when he was trying to be intimate with his girlfriend. He stared at his sister's perfect ass, which looked like just the perfect handful, if only he could-no, he couldn't take it there, he had to stop thinking of his sister like that for at least the duration of the stay here at the cabin.

"It looks great as always Maddie." He grunted sourly.

"What's the matter Bran, did I give you a hardon?" She asked mockingly.

"No! Shut up!" He snarled.

"Oh, I get it, you need some alone time. I understand Brandon, I wouldn't want you getting the wrong idea and fucking me in a horny daze instead of your girlfriend. See you by the lake?" She asked innocently. Brandon didn't even attempt to answer, and just sat there until Maddie smirked at him and left the room giving him a great view of her swaying hips. When she was out of view, Brandon gingerly got up and moved to the door and closing it, realizing that the door had no lock. Brandon went back to the bed and snarled in frustration at the boner he had for his sister, most guys usually found solace in their sister as someone who would give them a respite from the teasing of other women, but not his sister. His sister, was the reason for his thoughts of cheating on Ashley, thankfully they were only thoughts, but Maddie was right about one thing, he needed some alone time before he made a mistake in a lust filled haze. He unzipped his pants and lowered his underwear as he got ready to get to work.
