Susan looked at her brother stretched out on the sofa. At 18 he was 10 years younger than her and in his last year at school. She had watched him grow up, maturing through his teenage years into the attractive, toned form that lay before her now. Guiltily she admitted to herself that she found him sexy, that she wanted to fuck him.
She had been married for 8 years. Her husband was a good man who worked hard to give them a good lifestyle. Unfortunately his hard work meant he didn't have much time for sex and Susan had needs. It was these needs that were making her pussy tingle now as she imagined Chris, her brother, doing things to her that she really shouldn't be thinking.
Chris had come to stay with them for a week but Jeff, her husband, had been called away on business at the last minute. He had spent the weekend at home but had left this morning for a 3 day trip abroad. He had rung from his hotel just an hour ago to let her know he had arrived safely.
After dinner Chris had gone upstairs to shower. He had come down just wearing a robe and, as he sprawled on the sofa, it fell open to reveal his firm, muscular chest. Opposite him, in the chair, Susan sat wondering what else lay beneath the robe and how she could get to explore his body. Her pussy was on fire – she was filled with illicit lust. She wanted his young body close to hers, his firm cock pushing deep into her.
Susan stood up. "I think I'll go and shower now" she said.
"OK" replied Chris. "Maybe we can go out for a drink or something".
"I won't be long" said Susan.
Upstairs Susan enjoyed the warm water running over her sexed up body. Her hands roamed over her 36-24-35 figure and up through her long raven black hair. Her fingers probed her pussy, trying to find some relief from the pent up feeling of desire that she felt for her brother. It was no good – it wouldn't go away. She wouldn't be truly satisfied until she had his tool in her cunt. She stepped out of the shower, dried herself and went to her wardrobe. Her mind was set on seduction and she needed to choose her clothes carefully.
Susan normally wore conservative outfits that would be described as smart rather than sexy. She had met some of Chris's past girlfriends and she knew he went for the obvious, tarty type. Going through her underwear drawer she found a bra and brief set that her husband had given her for Christmas. She had worn it a couple of times but it wasn't really her style. Jeff had obviously bought it for his benefit rather than hers. Susan put it on and studied herself in the mirror. The lacy black bra pushed her tits up and together, giving her a magnificent cleavage. The matching panties barely covered her bush, which she always kept neatly trimmed.
Searching through her wardrobe, Susan tried to find something suitable. To have the desired effect Chris would need to be able to see the sexy underwear, so she needed something see through. Unfortunately she didn't possess anything transparent so she selected the next best thing. It was a white blouse that had a tailored fit. It wasn't exactly see through but, as she looked in the mirror, the outline of her black bra was clearly visible. Because it was a tailored fit she could leave the top buttons undone to reveal her ample cleavage. Below it she slipped on tight white trousers. Again, her black underwear was clearly visible but then he thought trousers would be difficult to get off quickly. Once she had Chris going she didn't want him changing his mind. Even he might draw the line at incest! Susan changed the trousers for white skirt that buttoned down the front. She fastened only the top three buttons and sat down on the bed. The skirt fell open so that it barely covered her pussy which was, by now, wet again. Her complexion was dark and tanned so she didn't need tights or stockings. Susan finished the outfit with black high-heeled shoes and went downstairs.
Chris was still in his robe on the sofa. He looked up as she entered. "Christ" he exclaimed. "I can't take you out like that!"
Susan pouted. "What's wrong?" she asked. "Are you worried that I'm too old for you?"
"It's not that" said her brother. "You may be dressed in virginal white but I'll spend all night fighting the blokes off you. Doesn't Jeff mind you looking like that?"
"Like what, exactly?" asked Susan.
"Well!" replied Chris. "You look so…HOT!"
Susan smiled. "Firstly, I'm dressed how I feel – HOT as you put it. Secondly, this is just for you. I don't dress like this when I go out with my husband".
Her brother shifted uncomfortably. He was having trouble concealing the boner that was struggling to escape from his robe.
