Bracing his arms on either side of him, he slowly rose to his feet. His ribs were really aching and the bump on his head throbbed. Allowing himself to get used to standing again, he stood there for a few seconds. Turning he went to the door, and slowly opened, peeked out and shuffled slowly into the room. Sarah immediately sprang from her seat on the couch and ran over to him, "You should still be in bed, sweetie."

"Sarah, I'm not sick, I just got a little bruised. I'm fine."

She wasn't having any of it though, and forcefully pushed him back into her room. "You got a lot bruised, you big dummy. Now lie back down and relax. We'll take care of you until you recover."

"Sarah, I can't lay in here anymore. You need your own room. I'll go lay in mine." He briefly pictured himself climbing the steps, each one jarring him on the way up, and winced in anticipation.

"It's the middle of the day Mike. I'm not using the room for anything." She had forced him back into the bed at this point, and he, in too much pain to argue, pulled the sheet back over him and sighed as his head hit her pillow.

"I'm just gonna make another escape attempt," he warned.

"Oh really?" She shifted her hips and her hands planted on them with a scolding look on her face. "I'll just have to lock you in."

He chuckled.

"Or maybe... I can just convince you to behave."

He felt the sheets rustling and looked down, curious as to what she was planning.

"Besides, I didn't get to look and see if something else got bruised."

He jerked, pain shooting through his ribs, as he felt her hand on his leg. "Sarah! What the hell are you doing?"

"Relax, Mike, no one got much sleep last night. Danni stayed by your bedside all night. She's in her room. Beth and Emma tried, but couldn't sleep and are both up in their rooms."

He relaxed slightly, but then felt her fooling around with his underwear. Her hands were warm and soft.

"We're alone and no one is going to bother us."

"It still feels wrong, them being in the house with us."

She leaned up closer to his head and grinned slyly. "It's making my pussy wet thinking about doing this with them here."

He couldn't believe how much his sister could surprise him, now that he'd been let into her sexual world. She was so... dirty. The thought excited him, too. She lifted the sheet higher and in one swift move, had his underwear down and off, tossing them to the floor. "Someone needs to reward you for being so protective of all of us girls." Her hands were gently rubbing his stomach as she smiled up at him, her chin resting on his thigh. A twitch shot through him and his cock throbbed slowly to life, rising up a few inches from her face. "It looks like someone agrees with me."

She grinned at him and slowly took her hands off his stomach, bringing them lower and gently wrapping them around his cock. She began to slowly rub her soft hands up and down, staring at her brother the entire time. There was a strange look of excitement, and he knew she felt naughty and she was probably getting wet.

The thought of her getting turned on hadn't ever crossed his mind, and now that thought caused his dick to harden, sticking straight up in her hands as they wrapped around it. She slowly pulled her face closer and he smiled as her tongue snaked out across her lips, wetting them and making them shine a little in the dim light. She pulled herself completely on the bed and positioned herself between his legs.

Mike was grinning in anticipation, watching his sister adjusting herself on the bed. He could see her cleavage as she squished her boobs into his legs and the mattress. Closing her eyes, she slowly parted her lips and bringing both hands towards her mouth, pulled him gently in.

"Ohmygod...," Mike moaned softly, causing her to smile and giggle on the end of his dick a bit. He could feel her tongue wrap itself tenderly around the tip of his penis, felt it lick his hole and travel down the shaft. She began to softly pump on his cock, pulling it slowly deeper and deeper into her mouth. He wondered if she was enjoying this, it certainly appeared so. She was taking great care to ensure that her lips were always over her teeth, and she always seemed to suck at the right moment and draw him further into her mouth.

"My brother has such a beautiful cock," she said, pulling it out of her mouth briefly before plunging it back in. His dick jumped at hearing her dirty talk, especially the brother part. Incest, naughty, wrong flashed through his mind and he groaned, a familiar feeling growing within him.

She pulled him out of her mouth again, "I love the way you feel in my mouth." Another quiet moan filled the room as she plunged him back into her mouth. She took him deeper and he felt the soft flesh at the back of her throat on the head of his cock, and then he felt it pulling back out of her mouth and heard her slurping noisily as he extracted it. The feeling of her tongue swirling around his shaft and the soft slurping noises she was making were pushing him dangerously close to the edge.

She pulled him out of her mouth again, knowing the effect her dirty talk had on him. "I bet you didn't think your big sister was such a good cocksucker," she said, licking the head again. "God I love sucking your cock," she said before pulling him in.

He teetered on the precipice of his orgasm, his cock deep in his sister's mouth again, her hands steadily pumping on his shaft, her tongue pasting his shaft with saliva. He glanced down; she was looking directly at him with her beautiful green eyes.

That image sent him over the edge. He tried to pull out, grunting quickly, "Coming," but he nearly fainted in ecstasy as she pulled him back into her mouth again, steadily pumping with both hands. His cock began to pulse hot semen into her mouth, eliciting soft yelps from her as her mouth quickly filled. "Oh... fuck... Sarah...," he gasped at her.

She moaned audibly and tried to hold all of her brother's seed in her mouth, but had to swallow, gulping it down as she felt more streams hitting her teeth and the roof and back of her mouth. He was still staring at her, and her at him as he shot stream after stream into her mouth. He could see her throat swallow several times as she emptied her mouth, only to have more piling up in it. Finally, after about fifteen seconds of coming, he finally stopped and melted into her sheets.

She pulled the cock out of her mouth with a soft popping noise, licked her lips and then started to run her tongue down the shaft again, cleaning any stray sperm off. The dick was quickly fleeing the scene of the crime, and soon was a sad, shriveled copy of its former glory.

"That was indescribable," Mike said at last as she licked and slurped on his shriveled penis, running her tongue along his balls. "Sarah, I think you can stop now."

"Don't' wanna," she said, raising her head and pouting at him. She conceded though, and reached over and grabbed a glass of water that had been sitting on the table next to him, swirling around in her mouth and swallowing.

"I wanted to make sure I got all of your sperm," she said with a wink.

He shook his head at her, still not believing that his sister could be so filthy. "God, the things you were saying were so damn hot. It was like you were in my head and knew all the right buttons to push." He glanced at her, wanting to ask her something but not knowing if she'd be offended.
