Note: This story was dynamically reformatted for online reading convenience. Siblings - 01 Jeff: a 14 year old boy in 8th grade, 5'11" tall, 130lbs somewhat "geeky" short dark blond hair. Amy: a 12 year old girl in 6th grade, 5'7" whispy thin 93lbs, shoulder length straight light blonde hair. Sue: a 35 year old "milf", divorced, an RN working hard to be both mom & dad, 5'10", 140lbs, wears a 36-B bra but prefers to be braless. On this warm day in mid May, Jeff walked home from the middle school, day dreaming about his mom, his sister, himself jacking off, the fact that he really needed to take a piss, and wondering what instructions Mom had left him for making tonight's dinner. He was always the first one home in the afternoons, usually getting there about 10 minutes after 3pm. His Mom usually worked until about 5:30, but left him clear directions for each night's dinner, and often it was prepared and just waiting for last minute heating. He went into the house and straight up to his room. Amy was only a little over a half a block behind Jeff for the last part of the walk home, they went to different schools, and their routes were the same for only the last three blocks. She watched her brother turn on the walkway to the house and disappear into the door. She was looking at his ass, she enjoyed looking at his ass. Jeff was dressed in baggy shorts and a Tshirt. Since their Mom worked to support them, and their Dad hadn't been around since she was 3, she had spent a lot of time with Jeff. In fact, over the years they had become much closer and more intimate than most brothers & sisters. She dropped her book bag just inside the front door, next to Jeff's, and went up stairs. His room door was wide open so she walked in. Jeff was shirtless, standing in front of his dresser with his back to her. He was beginning to show some muscle definition in his upper back and shoulders. His arms too showed that he had been working out a bit. Amy loved looking at his solid form, his square shoulders were wide and strong, she could see that his biceps were clearly defined. She just loved the idea that her big brother was becoming a "hunk". She stood in Jeff's bedroom door angled to the dresser mirror such that he could not see her reflection, he was standing there picking his nose. She watched as he pulled a large boogy out and looked at it on the tip of his finger. With a big smile, almost a "shit eating grin", Amy snuck up quietly and quickly grabbed Jeff's wrist. "What have you got, Jeffy?" She held his arm steady and looked at the boogy on his finger, and then into his eyes. He just stared back at her. "You were going to eat this, weren't you Jeffy?" She stared directly into his eyes, knowing what calling him "Jeffy" would do. He blinked and then nodded ever so slightly, but other than that didn't move or give any response. "You know you mustn't eat your own boogys, you're such a disgusting pervert." Then she pulled his hand toward her face and sticking out her tongue licked the boogy from his finger, keeping it on the tip of her tongue she stuck her tongue out farther so he could see his nose treat. He was just leaning in toward her when she pulled her tongue back inside and swallowed. "You little thief! I'm gonna get you back for that." "Oh yeah." "Yeah! I think I'll . . . mmm . . . I'm gonna piss on you." "Is that, my dear brother, a threat or a promise?" "Get your skinny little ass down to the hot tub and you will find out." Amy just stuck her tongue out at her big brother, turned and sashayed out of his room, accentuating the sway of her hips and butt as she went. She knew him too well, he would strip in less than a minute, leave his clothes in a pile on the bedroom floor, and run to the hot tub. But she was in no such hurry. Amy continued her slow sexy walk until out of sight and then darted quickly into her room. She too stripped, but much more slowly. Today she had worn a colorful, almost Hawaiian blouse, a tan pleated skirt that came down to just above her knees, a plain cotton training bra, and boy cut light pink cotton panties. Each of these she removed slowly, placing them on the bed in a neat pile. She looked at the bra for a few seconds, it did nothing at all to support her very tiny titties. Really nothing more than the slight bumps at her nipples, but in school all the girls in her class wore bras. A few of them were big enough to begin to need the support, but most were tiny like her. It was part of growing into the woman they would each become, to start wearing a bra early. And it nicely hid her nipples from the very childish immature boys in Mrs Bergdorf's sixth grade class. Amy took her little yellow polkadotted bikini from her second dresser drawer, she wasn't going to wear it right now, but wanted it handy incase anyone came to the house unexpectedly. Then she walked downstairs and into the kitchen. As expected Jeff had done nothing with the dinner instructions which their mom had left for him. Jeff was standing near the hot tub on the wooden deck area just outside the kitchen door. Their house was in an "L" shape, with the long side facing the south side of the street, the shorter leg of the "L" was at the east end of the house, and there was a row of tall cedars along the west and south sides of the yard so they were hidden, or at least they thought they were, from the neighbors. As Amy walked out the kitchen door, Jeff's already semi hard penis gave a bit of a jerk and became harder. He loved seeing his little sister in the nude. He just could not get enough of seeing her tiny little nipples which had just begun to sprout into small "nubbins". They were hardly big enough to call them "tits", but she was finally no longer completely flat chested. What did all the boys say in his junior high class? "It's what's upfront that counts." He suspected there was more than one meaning to this phrase, but for the life of him, he could think of nothing other than girls boobs when he thought of it. Jeff especially liked seeing her stand so that her slit was clearly visible. Amy had just begun to show a few peach fuzzy pubic hairs, but not enough yet to in any way hide the natural view of her feminine slit. It was the most exciting view he had of her, and one he never tired of just looking at. Amy standing with her nipples clearly visible, and her fully exposed slit hiding her pussy. If she stood with her feet about shoulder width apart, then her pussy lips spread in the smallest way and it seemed to emphasize her feminine nature. He continued to stare at his little sister as she slowly walked from the kitchen door. She stopped about six feet away from him and stood with her feet spread just over shoulder width apart. She placed her left hand on her hip, almost pushing so that her right hip stuck out sideways a little, her right hand went down to her pussy, and just the tip of her index finger pulled sideways opening her slit ever so slightly. She pushed her finger farther between her legs and her lips. Soon she felt the wetness of her excitement and rubbed ever so little, gathering up a drop of pussy juice on her finger tip. Stepping closer she held out her hand to Jeff, letting him smell the light but exciting fragrance of her sex. "How about you just have a little taste, Jeffy. Isn't this so much better than your boogys?" She just could not resist teasing him. She knew that even though she was two years younger, her sexy slutty behavior gave her a bit of power over him. He always let his small dick head do his thinking. Jeff stuck his tongue out just slightly as Amy waved her finger under his nose, then she placed the tip of her finger on his tongue and slowly pulled it away from him, so that he could taste her pussy juice. Quickly she put her finger back in her pussy again, gathering more of her sweet girly nectar and then gave him another taste. This time she pushed her finger deep into his mouth, stroking down on the back of his tongue. "Hey Jeffy, how does that feel" she cooed. "Just like sucking a little cock isn't it?" Once more she removed her finger from his mouth and put it between her legs, but this time she kept it just outside of her pussy lips. Looking him straight in the eyes, she dribbled a small stream of pee onto her hand. She loved watching his eyes as he watched her pee. What was it that boys found so fascinating about seeing a girl pee? Was it because it was hidden? Boys were so open and "out front" peeing with their cocks sticking out, but she usually just sat on the potty with everything hidden, and now here she was peeing standing like Jeffy did. Maybe that was what he liked so much. Once more she raised her wet hand to his lips. She traced the wet fingertip across his upper lip, and then pushed it into his mouth one more time. He sucked and tasted her pungent pee. She knew she had not peed all day at school, and that after this amount of time she would taste stronger, more pungent. Letting him savor her finger and then taking her finger out but letting him lick the palm of her hand she said, "Now you have had two tastes, pussy and pee. I think that's a pretty fair trade for one tiny little nose boogy." With that she turned quickly and walked back into the house. As she went, she called "Make dinner just like Mom said to in her note. I'll be back down stairs in half an hour. I expect to be hungry for more than just your boogies." She knew that she was being a classical "prick tease". He just stood there, mouth agape, hard cock totally unsatisfied, dripping precum. He really did need to pee, but she had walked away too quickly, and his cock was just a bit to hard to pee right now, he knew he would have to relax a bit. He didn't want to jack off out here on the deck behind the house, so he went inside to begin making dinner, as Amy and his mom had told him.
