"Hi ya Bro," Philips sister Lauren shouted as she opened the front door to their house. Philip smiled on hearing her words.
"Hi back," he said. She hung her black cardigan by the door and dropped her bag on the floor underneath it.
"Mom and Dad not home?" She asked to which he nodded.
"Both working late, again." He told her. She nodded used to coming home and finding her parents still at work. "Won't be back till about nine." He added something else she was used to. She wandered into the kitchen, where he was leaning against the table. Gave him a quick peck on the cheek and began to fish around in the fridge for something. This gave Philip time to admire the view. She was not technically his real sister. Her mom and married his dad when she was two and he had been seven. But they had both grown up together and she always called him her 'big bro'. Lately, however, he had been having very un-brotherly thoughts about her. She had grown up into a very sexy nineteen year old girl and Philip had found himself attracted to her quiet badly. She had a nice figure. Thin but not too thin.
She had a gently rounded face with deep brown eyes, a small nose and sweet mouth that always seemed to have a smile on it. Her mousy brown hair fell in waves down to rest on her shoulders framing her face perfectly. Her breasts were small, but well defined and shaped. Philip had seen her often enough in just her underwear, or even naked. She had a tight sexy ass that Philip would love to get his hands on, with long firm legs shaped by three years of dance and gymnastics lessons. Today she was wearing her work uniform, white blouse and a dark blue skirt that seemed too short for work. Her black shoes had a high heel that just accentuated her shin muscles and her small white socks had rolled down letting him see nearly all her legs. As she bent over in the fridge, Philip watched her and remembered the conversation that had taken place the previous weekend. It had been between him and Claire, Lauren's best mate.
The whole thing had happened because his parents had decided to have a cocktail party. They had invited a few friends round, which had included Claire and her parents. Lauren and Claire had known each other since infants school, and had been the best of friends ever since. During the evening, Lauren was her usual bubbly self, and always seemed to be around Philip. As she was dressed in a tight black dress this had a definite effect on him. To make matters worse she seemed to constantly be sitting by him or rubbing against him, in a most undignified manner. He had tried to ignore her but that had been impossible. Finally, he had fled to his room to escape her, knowing she would not dare follow him. He had collapsed on the bed trying to clear his mind of the images and thoughts going through it. Unable to do so he then decided to do the only thing he could think of to take away his desire; he had started to wank off. He had lain on his bed wanking off imaging Lauren was riding his cock with her ass. Just as he had been getting into the fantasy, he heard a small giggle that brought him up short. He had opened his eyes and to his total embarrassment saw Claire stood by the door watching him. Blushing deeply he had quickly pulled his sheet over himself to attempt and hide his cock. All that had done was to make her giggle even more.
"So she did have an effect on you." Claire had said he had given her a blank look. "Lauren, she's been trying to get a reaction out of you all night. From what I just saw I'd say she succeeded."
"What!" He had gasped. "I was not thinking of Lauren." He added quickly, too quickly. Claire had smiled.
"Yeah that's why you were whispering her name as you wanked off." He had felt himself blushing again. "Why don't you do something about it?"
"About what?"
"The fact you want to fuck Lauren." He had given her a shocked look.
"She's my sister for Christ's sake. " He had snapped.
"Step-sister and believe me she would not mind at all." He had sat blinking in surprise at that. "Come on you mean you don't know. Lauren's wanted you for the last three years. She's all but told you that she wants you and you've missed it. Poor girl has been thinking you don't want her. But she has seen you watching her; you've got her totally confused."
"I.I.didn't know. I thought she'd not be interested as I'm her brother."
"But your not her real brother are you, only her step brother and that's what matters. God the times she's told me how much she wants you. You know what, she wants you so bad she'd let you simply take her. In fact that's what she wants you to do."
"How'd you mean?"
"She fantasies about you coming into her room and just having her, or forcing her over a sofa or a table and taking her."
"Forcing her!" He had gasped. Claire had nodded.
"Yep, forcing her. Giving her no choice but to let you fuck her."
