Bobby and Jackie Ross had never been on the best of terms. Since before they left elementary school the brother and sister had been competing with each other for attention and almost always found themselves against each other. Rarely a day went by that the two of them didn't find something to argue about, or some way to try to antagonize the other. Things had improved in the last few months, but not by much.
Less than a year separated them. 18 year old Jackie was only eleven months and three days older than her brother was. She had just graduated high school, but the event was already overshadowed by her brother's eighteenth birthday. He would be entering his senior year of high school and Jackie knew that he would have nothing competing with the celebration of his graduation next year.
Jackie was tall, with curly brown hair and an attractive face. She was thin with smallish breast. Her legs were long and sexy, and the boys found her attractive, although she was easily overlooked by the shapelier cheerleader types at school.
Her brother, Bobby, was six feet tall, only a few inches taller than Jackie was. He had longish brown hair and an attempt at a beard on his face, although his whiskers just were not yet thick enough to accomplish anything more than what appeared to be a rugged weeks worth of beard, even though he had been trying for three months.
Bobby was average looking at best. He wasn't as good a student as his sister and had a temper. He had dated several girls but usually managed to drive them away before any serious relationship could occur. In fact, other than a few handjobs and one visit to a skanky looking street walker her gave him a quick forty dollar blow job in his car while he was wearing a condom, Bobby was basically an eighteen year old virgin.
Bobby had a few friends over for his eighteenth birthday party. His parents had even agreed to buy beer for the party, as long as his friends would be sleeping over. This was something else that Jackie resented, as her parents didn't permit that when she turned eighteen eleven months ago. Their excuse then was that Bobby, and some of her friends, were still under 18, even though the legal drinking age was 21.
The fact that Jackie was staying home for his party pissed Bobby off. He had been forced to leave his sister and her friends alone when Jackie turned 18. But now she was being permitted to hang out with his friends.
It wasn't just that Bobby didn't like having Jackie around. Jackie had found another way to piss off her brother. During the past two years she had given four of his friends blowjobs. While it was true that Jackie had found them to be cute. Her real reason for doing it was that she knew Bobby would find out and that it would really bother him, especially since it would usually put her between him and his friend. After all, what guy is going to side against a pretty girl who's willing to suck his dick against in favor of her brother?
Perhaps it was also the fact that his sister had helped three of those four achieve the first sexual experience before him that also made it worse. Despite his attempts to hide it, Jackie knew her brother had never had sex and often teased him about it. She didn't even know about the prostitute, but that would have only been worse for Bobby if she did know it.
The party went well, without any real problems between the two siblings. But as the night went on, and Jackie drank just a little more than she could handle, she began growing more and more interested in one of Bobby's new friends.
Jim was a very cute boy. He reminded Jackie of a singer in a popular boy band, and she could tell that he had taken notice of her.
Bobby noticed the mutual attraction and began to grow irate over it. Nothing further may have happened except for the fact that Bobby had cornered his sister and ordered her to leave Jim alone. This angered Jackie, and she decided that before the night was over she was going to add a fifth friend of her brother's to the list of her oral experiences.
The night wore on and it became time for everyone to crash. Jackie was sent off to her room while Bobby and his friends spread out to find places on the floor in the large family room, each with a blanket provided by Bobby's parents.
Before she left, Jackie observed the spot next to the wall where Jim was sitting.
Being all men, Bobby and most of his eight friends had no problem pulling off their jeans and sleeping in their boxers and tee shirts. Only a couple left their pants on.
When Jim got up to go to the bathroom Bobby quickly claimed his spot by the wall, knowing that it's location was the warmest place to sleep in the room. Jim didn't bother to protest when he returned. After all, it was Bobby's birthday.
Soon the lights were turned out and the sound of nine drunken young men snoring filled the room.
Jackie lay in her bed in her tank top and panties rubbing her pussy and thinking about Jim. She wanted to sneak into the family room and wake him up with a good blowjob. She knew that the room was dark enough to go unobserved if she remained quiet. She continued rubbing her clit, feeling her body nearing climax as she thought about what she was about to do.
Jackie loved giving blowjobs. She had perfected the art with several guys throughout high school. She had only fucked four, each being boyfriends. But Jackie was currently not in any relationship.
She brought herself to orgasm, then lay back, allowing herself to recover from her climax before getting up the nerve to sneak out of her room. She had to make sure that her parents didn't catch her, as they would likely kick her out of the house if she were caught.
Jackie put on her robe and quietly slipped out of her room. She went into the bathroom first, took a piss and then waited until she was certain that she could hear no one about before shutting off the light and sneaking back into the hallway.
She instantly regretted using the light in the bathroom. Now it was almost impossible to see anything in the dark. She made it to the family room and could make out the shapes of people and furniture, but little more than that. She knew the spot where Jim would be sleeping. She could tell that no one was near him. Hearing the sound of snoring and deep breathing, Jackie knew that everyone was asleep. She lowered herself to the floor and crawled over to the blanket-covered figure against the wall.
Jackie eased the blanket aside, happy to realize that Jim was wearing boxers. She slowly moved her hand to his crotch, parted the opening and reached in, gingerly taking hold of his cock. This was where Jackie learned something about her brother than she had never known before...
His cock stirred to life as she slowly played with it. Jackie felt it grow hard, and realized that this cock was larger than any she had experienced. It was thick enough that her fingers didn't come together, and she could put both hands side by side and still have the head exposed.
Bobby awoke, feeling his manhood being fondled. He was about to cry out when he felt a pair of lips slide over his cock and begin sucking him.
