Portia was twelve when her father married Annette. She had never known her mother and, being an only child, welcomed both Annette and her ten-year-old son, Connor, into her life.
As she grew, however, she found herself growing closer to Connor than she did to Annette, who seemed content devoting herself more to her new husband than to their two children. By the time Portia entered high school, she found herself making sure that Connor was occupied before going to cheerleading practice or out on dates. She was really beautiful, even at fourteen: tall, slender, with long dark hair and piercing gray eyes; she attracted a lot of attention even then. But she found herself drawn always back to her stepbrother.
He entered high school during her junior year, and she found herself growing more attracted to him every day. Physically, he wasn't as extraordinary as she was. He, too, was tall and thin, and his brown hair and brown eyes basically put him on par with most other boys of that age. He wasn't as popular as she, preferring science books to football. He found himself returning Portia's attraction, though somewhat hopelessly, as he knew she would never be a possibility for him.
When it came time for Portia to go to college, she chose a school far away, hoping that the distance would quench her growing sexual desire for Connor.
During that first year, Connor began filling out, and with his more muscular physique began dating Kara, a tiny sophomore with green eyes and enormous breasts. Portia, for her part, began dating Meyer, a med student who was nearly a body double for Connor, and though even she admitted that Meyer's personality left something to be desired, she slept with him as a sort of surrogate for Connor.
When she came home for the summer, she found her stepbrother to be even more attractive than she remembered, and grew immeasurably jealous of his blatantly sexual relationship with Kara, which he flaunted. Portia found herself touching Connor much more as the summer wore on, and he struggled to fight his all-consuming desire for her.
She returned to college in the fall near desolate, knowing that all of Connor's attention would now be on Kara.
She devoted herself to her schoolwork, and for a while was able to divert her thoughts from Connor. Spring break came quickly, and she decided to return home, knowing that their parents would be out of town, but thinking that her feelings for Connor were gone.
He was nearing the end of his senior year, and the week Portia came home was the week of his senior prom. They spent most of the week together, hanging out and playing like old times when he wasn't in school, so that by the time Friday arrived, they felt closer than ever. She fought her jealousy that he was going to the prom with Kara, and he fought the urgent need he had for her.
As he was preparing that night, Portia left him pretty much alone. It wasn't until he was almost ready that she stuck her head in to wish him luck. He was standing with one leg on a chair, tying his shoe. His tie was sloppy, and so she stepped into the room to help him.
"Your tie needs to be fixed," she told him, and he stood up quickly, startled.
"Oh...yeah," he said. "I'm no good at that."
"Well Kara will want you looking perfect, I'm sure," she said, laughing as she reached up and untied it. "Interesting suit, by the way." He was wearing a white suit with brown pinstripes.
"Yeah, it matches her dress," he said, wryly.
Her eyes refocused on the tie, which she now began to tie for him. As she straightened it, he gazed at her, thinking, "What if I just touched her..." then realized that he had touched her, and was now running his hands up and down her arms, which were still stretched out to him. Her eyes fluttered shut, and then opened and refocused determinedly on finishing his tie, but he could see her breathing had grown heavier.
He ran his hands up her arms and over her shoulders, caressing her gently before moving up her neck into her hair. He pulled the ponytail out, letting her long hair fall. As he ran his hands through it, she watched his face grow more abstracted, more determined. Finally, he placed his hands on her shoulders and looked her in the face. She had dropped her hands to her sides and gazed back at him thoughtfully, wondering, "What would happen if I just stepped forward?"
Instead of stepping forward, though, she just said, "Well, I guess Kara will be waiting," which came out chokingly, as if the words had forced themselves out.
He dropped his hands reluctantly and replied, "I suppose she will." Neither of them moved for a moment, and then she stepped away, turning toward the door. "Portia," he said, and she stopped, turning back toward him. Again they were still, and then she moved quickly back toward him.
He caught her in his arms and kissed her hungrily. She clung to him in desperation, crying as she offered herself up to him. He was crying too, murmuring against her mouth, "I love you. I know it's wrong, but I love you."
She felt his hands flying over her body, as if he knew that this was his only chance and he wanted to know every inch of her. "Stop," she said into his mouth, and he froze, knowing that she was about to end the whole thing.
Instead, she led him to the phone. "Tell Kara you're sorry, but you won't make it tonight." He called Kara, told her that he didn't love her, and then hung up, looking expectantly at his stepsister.
She took his hand, pulling gently, and he willingly followed her. She led him to her room and closed the door behind them. "If we're going to do this," she said, "We're going to do it right."
She pushed his jacket off his shoulders, and he tossed it on a chair as she undid his tie and tossed that on top of the jacket. He ran his hands over her arms as she unbuttoned his shirt and pushed it off, leaning forward to kiss his chest. She ran her hands over his now naked torso, kissing and licking her way to his neck.
He bent his head forward to meet her lips, holding her against him. She sat on the bed as he pulled off his shoes and socks, then he sat down and joined her.
She slid into his lap, straddling him as they kissed. He pulled hesitantly at her shirt, and she sat back to pull it off. He stared in awe at her slim body as she straddled him in a pair of boxers and a lacy black bra.
"You are so beautiful," he told her. She grinned, leaning forward to kiss him, and he lay back, pulling her on top of him.
For a while, they just kissed, their hands exploring each other, learning the ridges and canyons they'd only dreamt about before this. Finally, though, his hands began tugging at her shorts, and she stopped him. "Not yet," she said, kissing his stomach. "You first." She kissed a trail to the edge of his pants, which she unbuttoned and began pushing down. He lifted his hips, and she pulled the pants down and off.
Connor could barely believe that he was lying in Portia's bed wearing only his boxers. Her hands were shaking as she freed his cock from the boxers.
