Mike rolled over as dawn broke through the curtains hanging at his window. He raised his hand sleepily up to his face, rubbing his eyes and rolling over. There was only one brunette head of hair snoring softly in his bed.
"So um, sex?"
Mike sighed and shook his head. 'Not yet,' he thought.
"What's the point of getting out of bed if you aren't gonna hit that?"
'School, shithead.'
The voice was silent for a second, but then replied, sounding irritated.
"You realize you're insulting a voice in your own head, right dumbass? You called yourself a shithead."
'You think too much.'
He turned and brushed the hair away from Danni's face and leaned over to kiss her. She smiled and yawned, stretching her arms out, her warmth and softness drawing him in.
"You are irresistible," he said, smiling and kissing her deeply.
"Fucky fucky. Right now."
"Dude, chill," Mike said. He froze as Danni pulled away from him and confused look on her face.
"What's wrong? Why'd you call me dude?" she asked.
"Dammit MAN! You fuckin' idiot! Now she's gonna think we're crazy and not fuck me, you... us, whatever, anymore!"
'Calm down and shut the fuck up, let me handle this.'
"I uh," Mike stammered. "I wasn't talking to you."
Danni cocked her head and raised an eyebrow, not having to voice the question in her head.
"I know, I know. It's hard to explain. I just don't want you think I'm nuts."
"Mike, we're a family of siblings all fucking each other. Talking to yourself is the last thing that people would think is weird."
He shrugged. "I know, but it's just that, it's been going on so long, I've gotten used to it."
"Gotten used to what, baby?" She had a genuine look of concern on her face now.
"You're getting nowhere fast, slick."
"I've got a voice in my head," he said, waiting for a response.
Danni sat quietly for a few long moments before replying. "Mike honey, you are going to have to explain that a little bit more."
Sighing, he ran a hand through his hair and stood, moving to his computer chair to sit. "I've got something in my head that talks to me. I think things back to it and it responds. It's almost like I've got another little person in my head, a really, really horny one."
"Ooh, I like him already," she said, giggling.
"Ya DAMN RIGHT BABAY! Move over slick, I got this!"
"I'm serious, Danni," he said. "Sometimes he wants me to throw you to the floor and fuck your brains out."
"Well, where's the harm in that?" Danni asked, a mirthful look on her face. "As long as he's not telling you to kill us, or skin us and then kill us, or fuck us skin us and eat us."
"No, he's not that kind of voice," Mike said. "I think it's something that's left over from the trauma of losing mom and dad. I don't know why it's horny all the time though."
"Baby, it's part of you. You're the one who's horny. It's just a part of your mind that's had to deal with some pretty rough stuff at a young age. That voice is just the way your mind has adjusted. The fact that it's horny is just you being a young man."
He smiled, looking relieved.
"What?" she asked, climbing out of bed, her nude body moving towards him as his eyes automatically roamed over her.
"I just never expected one of my sisters to be so understanding."
"Oh baby, I love you," she said, moving close to him and brushing a hand across his cheek and wrapping herself up in his arms. "Nothing you could say or do will ever change that."
Mike inhaled deeply, squeezing as tight as he dared.
"So, I wanted to talk about something from last night," Mike said.
Danni turned and moved towards Mike's closet to find an old shirt. "Go ahead," she said, pulling one over her head that came to just above her butt, which was cutely peeking out.
"Well, I just wanted to know what changed your mind about having sex with a woman. I mean, don't get me wrong, I don't mind having sex with two women. I mean I had sex with Sarah and Emma, and then Sarah and Beth, and now you and Emma."
Danni turned and smiled. "Well, nothing," she replied.
"So then why did you have sex with Emma?"
She smiled wider. "I didn't, you did."
Mike sat, yet another confused look on his face.
She giggled. "Think, silly. Did I ever even touch her last night in more than a sisterly way? I mean sure, Emma and I have kissed, and I might have fondled her and she fondled me, but I wouldn't consider that having sex. I mean, she did suck on you after you were in me, but that's on her, not me."
Mike scrunched up his forehead.
"We simply both had sex with you, not each other. I have no desire to have sex with any of my sisters. The only reason I kissed her was because she's so like you, so it wasn't that big of a stretch."
Mike nodded slowly.
"What about the domination thing?"
"What about it?"
"Well, do you think it's weird?"
She shrugged. "Who am I to say what's weird or not? I like to swallow cum and I'm fucking my own brother. All Emma is asking is for someone to exert some control over her. I'm sure it makes her feel loved, makes her feel needed, besides really turning her on."
Mike smiled, pulling on his shorts and reaching for a shirt. Danni came up between his arms and got in one more hug and a quick kiss before heading off to her room.
"Okay, so that didn't go so bad."
Mike ignored the voice and headed off to shower.

Across town, Ashley wiggled slightly in her ropes as her brother checked the knots.
"Are you sure you're into this?" he asked her for the thousandth time.
She turned and looked back at him, "For the last time, yes. Now come over here and put the gag on and fuck me."
"You're sure that mom isn't going to come home any time soon?"
"Paul, if you don't get that cock inside me in about five seconds, I'm going to tell mom you're fucking me."
Shaking his head, Paul reached around her and pulled the gag around her mouth and tightened it. He fastened her blindfold and ensured she couldn't see. Moving back to her rear he leaned forwards and pressed his lips to her cute ass, moving slowly towards her crease. He glanced up at her as she began to breathe faster, her red hair pulled back into a ponytail. She moaned around her gag as he pressed his tongue into her slit, running it up and down a few times, then moving to her ass.
He stood then and checked her ropes one last time, her arms tied behind her back as she leaned forward on her knees onto the bed.
Dropping his boxers to the floor, he came behind her and gently rubbed his hand across her ass, bringing it back and then down in a hard thwack. She moaned and pushed her hips backwards, her ass pressing into his thighs.
"So my slutty little sister likes that, eh?"
She groaned as he spanked her again, one of his hands grabbing a handful of her ponytail and pulling her head back.
Her hips were wiggling quickly, desperately trying to work his cock into her pussy. He smiled and reached down with his free hand, gripping his cock and rubbing it across her pussy and then her ass, teasingly. Ashley seemed about ready to burst.
Paul rubbed his cock across her ass again and gently began to push it in. Ashley moaned as he pulled her ponytail, the tip of his cock pushing slowly into her ass. She moaned again as he inserted another inch, her breathing fast and shallow. He slowly pushed another inch in and then everything seemed to loosen and the rest slid in quickly. He stood there for a second while her ass adjusted to him. She groaned and wiggled, his hands still pulling her ponytail. He spanked her again. She gasped and began to come.
Paul smiled as his little sister had an orgasm, his cock deep in her ass. He pulled back and pushed himself in again, and then again, slowly building up speed as he pulled her hair and spanked her. He lost count of how many times she came. Eventually, he filled her ass full of his cum and pulled her gag and blindfold off.
"I'm gonna go shower," he said, pulling at the rope that held her hands behind her. He stopped before she got free and smiled. "I think I like you like that. I'll free you when I'm done."
She smiled and shrugged, her face a mess of smiles and sweat.
Paul had just turned on the shower and stepped in when she heard the key in the front door.
"Fuck, PAUL!" she yelled.
"What?" he asked, peeking out from behind the shower curtain.
"MOM!"

Mike closed the bathroom door behind him and turned on the water. He turned and looked at his reflection in the mirror. He was still bruised in places, including a large spot on his ribcage. There was a soft knock at the door and Beth's blonde head peeked in.
"You doing okay, hun?"
Mike smiled and nodded. "Yeah, just taking inventory of all my bruises."
She entered and closed the door behind her. Her hair wasn't combed, but she was gorgeous nonetheless. She was wearing one of his threadbare white undershirts, her nipples clearly visible. Mike felt old faithful beginning to stir.
"Let me guess, you're not going to tap that. Nah, there's no reason we'd want those supple breasts in your mouth. Ass."
She noticed him trying not to stare. "You've seen a woman's body before Mike, I'm just your sister."
She moved over to the sink and began to brush her teeth, her breasts shaking as she wiggled the brush around her mouth.
