There was only a hint of guilt lingering in the back of Nathan's mind as he flipped through the pictures of his sister's best friend, Jes. It wasn't common for him to be attracted to anything that would remind him of his sister. Sure, she was an attractive girl, but she was his sister, and thus, could never qualify as sexy. But as Nathan's sister, Marissa got older, he noticed that her friends did, too. Now that she was about to become a senior in high school, she began bringing older girls home, girls closer and closer in age to him.
The pictures that he found were of a photo shoot that Marissa took of Jes for her photography class. The first few were tame enough, Jes's beautiful smile in the sun, framed by her light, curly hair. The setting was of the secluded lake not far from their wooded house and he knew the area well. The photographs continued: Jes posing with some flowers, Jes kicking her feet in the lakeside, and then, something he hadn't expected. Jes throwing off her blouse in a playful manner, smiling brightly as the sun glistened off her full, pale breasts. Nathan imagined her laughter in his mind as he felt his cock growing harder in his jeans. He imagined Jes squealing with joy as she climbed out of those little grey shorts and leapt into the lake; droplets of water frozen in time and her exquisite pleasure were captured on paper with the cunning use of film and chemicals.
Nathan couldn't wait any longer. He displayed the photographs around him and loosened his jeans enough to step around them and sat on the edge of his bed. As he watched the silent movie splayed out of the floor, he stroked his painfully throbbing cock. He imagined himself there with Jes, touching her body, licking off those perfect droplets off water off of her shoulders, down to her breasts, until impulse forced him to take her nipple into his mouth. He wondered if she'd sigh with pleasure or giggle with the naughtiness of the act. Either way, soon, Nathan imagined Jes would want him as much as he wanted her. He'd reach down into water between her legs, sliding the tip of his finger along the slit of her pussy, feeling where the cool water met her own kind of slick, warm wetness. Once he found her clit, Nathan was positive that Jes would wrap her long legs around him, clamping her mouth to his neck, kissing and sucking, leaving marks that he would cherish for as long as they would last.
Finally, as her heavy sighs seemed to beg him to plunge his cock into her aching vagina, she'd whisper....
..."I take it you like the pictures?"
The voice startled him so much, he nearly fell off the bed. There in the doorway of his room, stood the woman who only existed in the photographs that were now scattered all over the floor. All he could do is look at her helplessly, his red-hot cock still in his hand.
"Shh." Jes whispered. She entered the room and silently closed the door behind her. "Marissa said she wouldn't be home until later. I only came to see the pictures she took for her natural body photography project."
She smiled a wicked smile. "But I can see that you've found them first."
Jes carefully held her bottom lip between her teeth and looked Nathan over, much the same way he'd been memorizing every part of her body from the photographs.
