Feeling that something was going on between her son and daughter created a deeper shame within her. She was ashamed because, if something was going on, she had no way of stopping it. She didn't have the courage to talk to them about something like that. She would be much too shy to talk about pleasures of the flesh. She would make a fool of herself, she felt.

Although Joann successfully concealed the raging heat of her desires, Judy and Dave made no pretense of what they wanted. Young and desirable, healthy and tanned by the summer sun, the brother and sister had, apparently, inherited their mother's erotic hungers. But unlike her, they took delight in it.

At the moment they were sitting in the pickup. It was parked inside the garage, facing the huge door. The door was up, and bright light streamed into the garage. The pickup meant more to Dave than his mother suspected. It was a place he and his younger sister could be alone.

Judy was now pressing against her brother, a small tit smashing into his upper arm. Her hot little hand was rubbing up and down his thigh, caressing. Her breaths were hot as she breathed with growing excitement. Her hot blue eyes gazed at the bulging of his cock inside his jeans. Dave's open palm rested on his sister's thigh, gently squeezing the sweetness of her flesh.

A soft gasp came from Judy as she moved her hand slowly up her brother's thigh, her fingertips just touching the bulging place where the head of his cock swelled. As she placed her hand on top of Dave's cock, there was an excited catch in her breath. She felt his prick throbbing against her palm, and she exerted a gentle pressure, bringing a moan from him. His fingers squeezed harder at her thigh.

"Can I take it out again, Davy?" she asked in a low, young voice. "Is it okay if I take it out of your pants again?"

"It's okay, Judy," Dave replied, his voice husky.
