Mike sighed. He knew what Danni would say if he asked her, though. She'd call him a freak, hit him with something and then wait for him to plot his revenge so she could hit him again. She was his scourge. He hated her. He'd love to stick something pointy into her and make her scream. Wait, no he wouldn't. Don't go there, don't go there.

"Sometimes you make this too easy."

Okay so he didn't hate her. It was his sister; there had to be law somewhere that said he had to love her. Wasn't there? If there wasn't one, then he did hate her.

She'd always been mean to him, though, and Emma as well. Growing up she'd made their life hell. Emma was easier to make cry, and thus get Danni in trouble so Mike had always been the main target of her pranks, ridicules, and thrown pointed objects. She'd get in less trouble from Sarah that way. She used to love calling them M&M, singing the kissing song when they were kids, they were so inseparable. She was the very reason the name stuck, especially since she spread it around the entire school.

The voice was trying to force his thoughts back to its favorite topic. It would be summer soon. He'd have to start cleaning the pool again.

It was already summer actually, he just didn't want to admit it and have to actually start cleaning it. They'd always had such fun at the pool, though his sisters liked to sunbathe way more than swim. Especially Danni, she'd already started laying out in fact, even though the weather was still mild. Well, mild for Texas. Summer if you were from New York or Boston.

Danni did swim though, just hadn't started yet. She used to swim in high school. 200 meter breast stroke and the Medley Relay. Mike started to picture her. Swimming in the pool in her small yellow bikini, breasts bouncing up and down and up and down and...

"Breast stroke..."

"YES," Mike thought, "she's attractive. Can we PLEASE move on?" The voice was giggling uncontrollably in his head, it really loved to torture him.

His thoughts drifted to his eldest sister. Eldest sister. The term eldest made him laugh. She was only 24. It occurred to him then how close in age he and his four sisters were. He and Emma were 18, nearly 19. Beth was 20, Danni, 22, and of course Sarah was 24. His parents must have been really into having kids. He desperately hoped that the voice wouldn't try and go anywhere with that thought. "Even I have limits, dude."

Sarah had been handed the responsibility of looking after her family at 17. It hadn't been easy on her. Mike didn't know how she'd handled it. There was a great strength in her, and also a great caring. She finished raising him and his sisters, though Danni would never admit it. She was shorter than him, thin and was usually cleaning something.

Their parents had both been doctors and had left them financially comfortable, but you wouldn't know it. Sarah had always been in charge of everything related to all the finances. Mike didn't even really know how well off they were, until he'd gotten older. Sarah always gave to her family first and herself second. She was wise and so very sweet and caring. He swore at the voice in his head silently, wondering why he always had a sister pop into his head when he started to cum. It happened every damn time. He felt like a degenerate pervert. He looked at the clock again. 5:35.

It was going to be a long damn day. He stood and went to the bathroom to shower. After they'd moved out of their parent's old house, Mike made damn sure that they had more than one bathroom. He wasn't going to compete with four other girls time. He still had to share with Beth and Em, but it wasn't as bad as trying to use Danni's. Sometimes it looked like some creature made out of makeup and hairbows had exploded in there. Danni could be such a slob for having such an impeccable body. She'd spend hours on herself and not a minute cleaning anything up. She always had somewhere to go, someone to see, or something to do.

He got in the shower, turning the water to hot.

She could be a colossal bitch sometimes. He'd never known her to not be calling him or Em something, tossing an insult or a heavy object at him. He wondered if she acted that way around any of her myriad of friends. Was that her role in her group of friends? Was she the tempestuous bitch that could fly off the handle at the drop of a hat? What did those guys she went out with see in her?

"A nice rack, an exquisite ass, a perfectly toned stomach..."

Besides the obvious, of course. She was definitely hot. That wasn't the point. He shook the thoughts of her out of his head.

He obviously needed to get rid of some of his raging male hormones. He grabbed some shampoo and squirted it in his hands. He started rubbing his dick, trying to concentrate on a fantasy. He quickly became erect and could feel the orgasm easily building in him. The bathroom was filled with the wet sound of his hand pleasuring himself and he desperately prayed that the girls in the house were still asleep or deaf, or both. His thoughts drifted briefly back to Danni, bouncing up and down and up and down... He shook his head, internally scowling at the voice, forcing his thoughts back on the cute redhead in his fantasy. So close now, he could feel it rise in him like a wave, relishing the feel of his first orgasm of the day.

The voice was biding its time. It knew the perfect time to strike.

Mike was very distracted at that point and didn't hear the knock at the bathroom door. Emma peeked in, saw that it was her brother and not Beth in the shower and started to pull her head out. Then she heard it. It sounded like something fleshy was rubbing something else fleshy and wet. She put a hand over her mouth, stifling a laugh as well as a cry of surprise, figuring out just what the hell the sound was. She thought briefly about leaving, but a kind of morbid curiosity filled her.

He still didn't hear notice the door had opened. Everything kind of faded out as he started to climax. A thousand tiny sparks went off in his head... and then the voice struck.

"Oh Danni."

A streamer of cum shot out and hit the shower wall, while images of Danni bouncing up and down on the diving board, her perky breasts bursting at the small bathing suits she wore, flashed through his head. "Oh fuck me," Mike said out loud as he began to shoot his seed onto the tile in front of him. "Oh Danni," he blurted out as the images continued to flash through his head.

Emma stopped. "Oh Danni?" she thought, suddenly not so mirthfully amused at catching her brother jerking off. Oh Danni? What the fuck was he doing? Was he actually fantasizing about Danni? He hated her. Wait... what the fuck? "Oh MY GOD!" Emma froze as she realized she had spoken out loud, and slapped a hand over her mouth again.

"Damn it to hell, not again," Mike said loudly, mostly at the voice in his head, which incidentally was cackling in glee. Why the hell did he just yell Oh Danni? Damn it to fucking hell.

"Oh MY GOD!" he heard just outside the shower. He froze. He really hated when images popped into his head when he was coming, and it was always one of his sisters.

Thinking he had sensed her spying on him, Emma yelped loudly and pulled her head out, slamming the door behind her and running to her room. She dove into her bed and couldn't stop laughing. Great peals of laughter rolled out of her as she desperately tried to smother them under her pillow.

"Oh fuck," Mike groaned. Which one was it? "Please tell me it wasn't Danni." Oh god, oh shit, oh lord, oh no... his brain rambled. What the fuck had just happened? Why the hell did he just blow his load thinking about the one sister he hated? What the fuck was that about?" Mike leaned forward into the stream of water and closed his eyes. He felt like a deranged asshole. "Shit... I must really need therapy."

He got out, toweled himself off and stomped off to his room to get dressed.
