Nick stood outside his sister's window, watching her suck off some random guy. It was getting to be almost too much. Ever since her birthday party two weeks ago, when the exchange student from Rome had given her that creepy-looking book labeled "Black Magick," she'd taken to experimenting with any guy she could get a hold of, and with the body she had, Nick knew she could have anyone. Her breasts were large but firm and appeared soft to the touch, with perk little nipples that seemed to scream to be sucked. Looking at her naked in the window now made Nick hornier than he had ever been, but he tried to hide this fact so carefully that even he himself would not realize it. It was his sister Elisabeth, for Christ's sake! His sister, who he took the bus to school with every day. The sister who he had to wait an hour outside the door of the bathroom for every morning. He wasn't standing outside her window in order to gawk at her, even though his fly was undone and he couldn't help stroking his cock through his underwear. He was outside because he was worried about her. It wasn't healthy to have sex with so many people. He had been pretty sure she was a virgin only a couple of weeks ago. One of the boys at a party had suggested playing a kissing game and she turned bright red and fled the room. Nick found her in her bedroom crying into her pillow. It had taken a lot of work to get her to return to the party.
Elisabeth swirled her tongue around the head of the boy's cock, gently nibbling on its soft underside, making him moan. He didn't look very experienced and probably wouldn't hold out much longer, Nick thought. Nick's entire hand slipped under the elastic band of his underwear. He rubbed himself quickly, all the time pretending to himself that he would never do such a thing. Elisabeth sat up and her breasts bounced slightly. Nick moaned through his teeth and continued watching. Her pussy came into view for a brief moment, all pink and juicy, like a morning rose, covered in delicate strands of red hair, and then it disappeared again, covered by her leg. Her lips parted and the cock began to slowly disappear into her sweet little mouth. Inch by inch, she took in the whole thing, all the way up to the base, so that the boy's coarse brown pubic hair rubbed against her angelic little turned-up nose.
Nick whimpered more loudly. He was having difficulty keeping up his pretence under his own desperate urge to cum, and through he told his fingers to stop, they would not obey and continued to mercilessly pleasure him. The more they tried to rob him of his pretext, the more he clung to it, begging his lust-raked brain to think chaste thoughts about his beloved sister, whose head bobbed up and down, her soft pink lips parted, encompassing and expelling the sizable member she was so expertly toying with.
Nick's cock was on fire. Each touch sent little shocks through his body. He began to twitch and writhe, still standing half-concealed behind the apple tree. Elisabeth bobbed down one more time and then pulled free, cum dripping from the corners of her mouth. She lazily wiped it with her fingers and drew little circles around her nipples with the excess. She swallowed the load with one big gulp and then threw the boy from her room. When he departed, she turned and looked at the apple tree. She was still naked, and the way the light shone on her to emphasize her breasts and the curves of her hips seemed somehow almost demonic.
Her eyes seemed to catch Nick fixed on the spot. Cum issued from his cock as though shot out of a handgun, messing up his clean white underwear. Elisabeth smiled, and covering herself with a small towel, left Nick standing alone in the yard, cum dripping down through the elastic and into his pants.
Nick knew he had no time to sneak into the house and clean up because his father had called him this morning from New York and insisted that he have the lawn mowed before lunch. The whole morning, while Nick mowed the lawn, he though about what had happened. Had Elisabeth really seen him standing outside her window, or had it all been his imagination? Elisabeth wouldn't understand that he wasn't interested in her sexually. She'd get confused, maybe hurt. He hadn't been standing outside her window because he was a pervert, but because he was honestly worried, and no matter what tricks his naughty fingers had played on him, he wasn't going to forget that he was out to protect his sister.
When the family sat down to lunch, Elisabeth was wearing a little cotton dress that ended three inches below her butt. Nick didn't know where she had bought it, but it was much shorter and much kinkier than anything Elisabeth had worn to the table yet. It was pink and had ruffles along the neck and sleeves, and was adorned with little pockets that covered Elisabeth's breasts. It was more like the sort of thing a little girl would wear than a grown woman, and that, rather than anything about the length or the cut, made it look so obscene on his sister's womanly body.
Their mother, Susan, yelled at Elisabeth that it wasn't proper clothing for a family lunch, but Elisabeth explained that she would either wear the dress or nothing at all, and so Susan gave in and let her wear the obscene outfit. Nick couldn't take his eyes off of it. The dress was so short, it gave him the impression that he would see her panties if she ever moved wrong, and yet she didn't take any special care to keep herself covered up. She sat with her legs spread wide apart, eating her food with apparent satisfaction. She took second and third helpings, oblivious to ideas of watching her waist line. Nick felt his cock swell in his pants. Elisabeth was sitting facing him, and he was desperate for a chance to peer under the table and see what color panties she was wearing. He once had a pair of bright red lacy ones that made him drool to think about. He had stolen them out of the laundry basket a month ago and hid them under his pillow, since he liked looking at them so much. But his mother had found them when she changed his bed sheets, turned redder than the hue of the lace, and grounded him for a week. Nick would never let himself so much as think of it, but the smell of the panties alone had been worth it.
He struggled to focus on his food and not on what was between his sister's legs. This was hard to do, because every time she opened her mouth to take another helping, he could not help but see her lips parted by the boy's cock. Every time she shifted her weight, he would remember the way her breasts looked when they moved. It was almost more than he could bear.
"What's wrong with you?" his mother asked. He shot up in his seat. He couldn't believe his mother had managed to get behind him. For a horrible moment, he thought for sure she had seen the bulge in his pants and was about to confront him about it, but the moment passed and his mother continued, "you're hardly touching your food. Look how much your sister is eating, and she's already finished her growth spurt!" This harmless statement acted to remind Nick of the time when his sister first began to grow breasts, and he blushed deep red and tried hard to concentrate on forking the tomato on his plate. He thrust three times, but each time he missed and the fork hit the enamel. Finally he succeeded, but in his earnestness, he pushed too hard and the tomato erupted with such force that seeds flew across the table and landed on his sister's face and breasts. He watched in wretched suspense as a large piece of tomato began to roll down Elisabeth's cheek onto her chin and then drip slowly onto the table.
