His cock felt hot, too, very hot. She gazed at his cockhead, swollen smooth. Staring at the tiny slit in the tip, she watched moisture seeping from it. She moved her other hand between her body and the seat. She stroked her swollen clit with a light finger, and began moving her fist up and down her sleeping brother's cock. She panted softly, her eyes swimming with excitement.
She tried a tentative squeeze.
Jimmy moaned, but didn't wake up.
Sharon paused, watching him anxiously, ready to jerk her hand away if he stirred and started to open his eyes. She didn't want him to catch her with his cock in her hand. She didn't want Jimmy mad at her.
There was one year to the day between their ages, with Sharon being the older. They never knew their father. All they knew was he had left them a month or so after Jimmy was born. Raised without a father, they didn't miss one. They knew, too, that their mother had been very young at the time, but Kathy had managed quite well with them. There had been a few men who wandered in and out of their lives, but no one important, no man that stayed long. Kathy had told them she simply did not want to get married again, not yet.
In the truck, Kathy was letting the young man know how friendly she was. Concerned about the warranty on the car, Kathy was letting the man know, in subtle ways, that she could pay him. Her skin was left halfway up her creamy thighs, and she sat with her shoulders back, tits thrust forward, smiling and chatting with him. She was aware of his interest in her. She saw his cock half-hard inside his grimy jeans.
