Over the next few days, Jill and Jimmy didn't exactly avoid each other, but they were a bit less talkative than usual. They really couldn't avoid each other because they both slept upstairs and shared a bathroom. They both, however, could feel that there was a bit of uncomfortable tension when they were near each other.
Every time Jill thought about what had happened between her and her brother, she blushed and felt pangs of both lust and guilt. How could she have allowed herself to do such a thing? She was a good girl, and she wanted to stay that way. She was well aware, though, that she was now a woman with the desires and needs of a woman. After Jimmy had gone back to his room that fateful night, she had quickly shed her housecoat and masturbated, thinking only about her sexy brother and what her body would love for him to do to her. She admitted to herself that there were no other boys or men who had ever turned her on as much as he did. She was actually fearful of getting into a discussion with him about anything, afraid that it might lead to an intimate talk of some kind -- and who knew where that might lead?
She couldn't get the image of her big brother's massive cock out of her mind. She especially couldn't help but dwelling on the sight of copious amounts of cum jetting into the air. It had been, undoubtedly, the most arousing thing she had ever witnessed. From the moment that she got a drop of his pre-ejaculate on her tongue when she kissed his cock, she had realized that she was addicted to it. When, moments later, she had purposely aimed his spewing cock at her mouth and had ingested a large, warm dollop of his delicious cum, she had felt a euphoria that she had not forgotten. She had felt like a wild animal as she had eagerly sucked the cum from his fingers when he wiped her cum-covered face and fed her his sperm. Then they had kissed, swapping mouthfuls of his luscious seed.
As much as she tried to tell herself that nothing like that could ever happen again, the more her body craved it. Was it the fact that she had never been intimate with a boy before? Was it because her attraction for her big brother was undeniable? Was it the taboo element of what they had done? Was she addicted to cum? She longed to taste it again. There was nothing about it that she hadn't loved. She loved how it looked, how much of it there was, the warmth, the taste, and even the smell of it. She became aroused every time she thought of it. And was it just her brother, or would she react this way to other men? She didn't know, but her fantasies were only of her brother.
She felt perverted when she rambled through the dirty clothes and found his soiled boxer briefs and sucked at the crotch, her nose detecting a faint smell of cum. She searched his room and found a handkerchief under his bed. The smell and the stains told her that he undoubtedly had wiped up with it after he had masturbated. She hid the handkerchief in her room and took it out and smelled it and even licked it while she masturbated. She felt insane and could think of nothing else.
Jimmy was ashamed of what he and his sister had done. He wanted to talk to her about it and assure her that it would never happen again. It was all his fault. He had left the bathroom door open, and she had seen him jerking himself off. Even after that, he could have left well enough alone and never mentioned it. Going to her room to talk to her about it would have been fine, but it was wrong of him to tempt her by asking if she would like to watch him again. He felt that he needed to talk with her again as soon as possible, to apologize to her, and to make sure that she agreed that they could never do such a thing again.
Meanwhile, he looked forward to Friday night and his next date with Allison. He tried with all his might to focus on her and to forget what had happened with Jill. Allison was a beautiful girl. Her long, almost black hair; those beautiful blue eyes that sparkled when she looked at him; her mischievous grin; those long, long, long, shapely legs that he could just imagine wrapping around him; those magnificent breasts! She was just a living doll, besides being smart and funny. Best of all, she liked him. He had really thought that they might have sex the previous weekend and she even admitted to him that she wanted to!
When he had asked her Sunday, at church, if they could go out again soon, she smiled, showing off her perfectly straight white teeth. She took his breath away! "Well, how about Friday night?" she had asked. "Mom is out of town this weekend. I think Daddy is going to go see some of his buddies Friday night. We can get pizza and watch TV. We don't have to go out..." she winked, "unless you want to, that is."
Before the incident with Jill the previous Friday, Jimmy would have been ecstatic with anticipation all week long. He was, in fact, but he found himself daydreaming about his luscious little sister and what they had done. Jill wasn't, in the eyes of most, as beautiful as Allison, but she was gorgeous to Jimmy. He'd always thought of her as cute, but now he thought of her as a gorgeous, fully mature woman.
The previous Sunday, when the family attended church, Jill had worn a sleeveless summer dress that had tastefully accentuated the curves of her body. Jimmy noticed that her bottom had filled out, that her legs were perfectly shaped, that her breasts had gotten larger. He had seen her any number of times in her bedtime attire -- usually a very long t-shirt that hugged her body but had never really dwelt on it much. That night he was laying on his bed reading when he heard her come into the bathroom. The door was open to his room, but she didn't close it. He could see that she was just brushing her teeth, and as she did, he scrutinized her body through the slightly tight t-shirt. He could see the outline of her bikini panties and her ass jiggled slightly as she moved. He focused on her breasts, wishing that the shirt was tighter. He thought, or imagined, that he could see the outline of a nipple.
Jill finished brushing and stepped into his room to wish him goodnight, then went back to her room. Jimmy closed and locked the bathroom door and jerked himself off, thinking only of his sister. Allison never entered his mind.
Every time he saw Jill that week, he surreptitiously examined her body. He was astounded that his very cute, even beautiful, little sister, possessed such a sexy body. Yes, he had thought about her when he masturbated before, but now she just looked a hundred times sexier to him. She was beginning to dominate his thoughts. He rationalized that it didn't make sense to be thinking about his sister, no matter how sexy she was, when he was dating perhaps the most beautiful girl in town.
Jill wondered if Jimmy was thinking about the previous weekend as much as she was. She had noticed him checking her out a few times since then and concluded that he really did find her attractive. She wondered if he had any idea just attractive and sexy she found him -- and if he did know, would he ever try to do anything about it?
Jimmy had mentioned at supper one night that he was going out with Allison again on Friday night. Their mother, Lilly, was ecstatic and commented that they made such a fantastic couple -- both so good looking and both such good "kids". Their dad, Keith, grinned and commented on the fact that, "like Father, like son," Jimmy really knew how to pick the beautiful women. Lilly blushed and smiled. Jill fought a pang of irrational jealousy.
Friday came and Jimmy had showered and gotten dressed for his date. He noticed a text from Allison: DAD MAY BE HERE UNTIL AROUND 7:00. LET YOURSELF IN WHEN YOU GET HERE. DAD JUST OPENED THE POOL TODAY AND WE'RE TAKING A DIP. BRING YOUR TRUNKS IF YOU WANT!
Jimmy had seen Allison in a bikini before. His cock lurched at the very thought. That killer body in that tiny bikini! Wow! He rummaged through his dresser until he found a pair of trunks and prepared to leave.
Suddenly the bathroom door opened, and Jill came in. "Hey!" she smiled. "Ready for your date?"
"Yeah, I'm just about to leave." He saw her looking at the swim trunks in his hand. "Jill's dad got their pool ready to swim in today. She says we can go swimming tonight."
Jill felt another pang of jealousy. Jimmy could read it in her face. "I'd love for you to go with me... but, you know... it's a date. She wants me all to herself!"
He wished he hadn't made that last remark, but Jill replied, "well we both know what happened when that happened last time." She grinned and then imitated their mother, "Young man you know right from wrong. You behave yourself around that girl." She angrily wiped a tear from her eye. "I'm sorry. I just... I'm so mixed up..."
"Jill, you're the sweetest, prettiest, most adorable little sister..." he said as he took her in his arms and kissed her cheek. "I love you," he gasped. Then he was gone down the stairs.
Jimmy arrived at Allison's house at around 6:30, and hadn't realized, in his haste to see Allison, that he had arrived much earlier than the time on which they had agreed. His phone pinged just as he pulled in the driveway -- a text from Allison: IF YOU'RE GONNA SWIM, YOU CAN CHANGE IN THE UPSTAIRS BATHROOM. THEN COME DOWN AND JOIN US. DAD WILL LEAVE SOON. SEE YOU AROUND 7:00ISH.
Assuming that his early arrival wouldn't matter, he quickly went upstairs and changed. He was wondering what kind of bikini Allison might be wearing. As he passed by her parents' bedroom, on a whim, he went in and looked out the window on the pool. This was the only room in the house that gave an unimpeded view of the pool. He liked the idea of getting a good look at Allison before he went out to the pool. He knew he was going to gawk at her when he first saw her, so this was a good way to acclimate himself. He didn't really relish the thought of her dad watching him lustfully checking out the body of his youngest daughter.
What he saw was the single most shocking thing he had ever seen in his life. Allison's dad was sitting on the edge of the in-ground pool with one hand on Allison's head. Jimmy couldn't see well, but apparently Allison's head was slowly bobbing up and down between her father's legs.
What? Was Allison really giving her father a blowjob? Surely there was another explanation? Jimmy realized that this should be totally disgusting to him, but it wasn't. It was one of the hottest things he had ever imagined! He quickly went to the other window in the room, hoping for a better angle so that he could see for sure what was going on.
Sure enough, the angle was better. Allison was standing in the pool in a tiny white bikini. From this vantage point, her bikini bottom looked like a tight pair of panties. Her dad's head was thrown back as he guided his daughter's head as she, apparently, sucked his dick. Suddenly she stopped and kissed her father directly on the mouth. Jimmy could see her hand moving in his crotch. They kissed like lovers for several seconds, then she went back to her task. Her father put both his hands in her hair and grimaced. Jimmy imagined that Allison's dad was unloading in her mouth. Presently, Allison stood and placed a hand on her dad's face and kissed him again. This time it was an even deeper kiss; Jimmy thought back on the previous weekend when he and his little sister had shared a similar kiss, swapping his cum back and forth. It was, undoubtedly, the hottest thing he had ever experienced -- and now his beautiful girlfriend was doing the same thing with her own father??
Jimmy was flabbergasted. Not only was it shocking that the "good girl" Allison would do such a thing, but that her dad, Mr. Fleming, a Deacon at their church would do this with his own daughter! And, on top of that, didn't they know he was coming over? She had just texted him about it, hadn't she? Of course he was half an hour early, so that would explain it.
Jimmy was sporting an erection that he knew he couldn't get under control without beating off. He quickly went back to the bathroom, stood in front of the mirror, and stroked while he admired the length and girth of his magnificent prick. He loved how purple and shiny and wet the head of his cock got when he was aroused. It didn't take long. Long, thick arcs of thick boy-cum jetted from his cock, spraying the mirror and the counter. He quickly grabbed some toilet paper, cleaned up his mess, and headed downstairs.
