Picking up her son's shorts, Karen pressed them to her face, inhaling his scent. The throb between her thighs brought a soft moan from her lips.

Looking around to make sure she was alone, she turned Robbie's shorts inside out, pressing the crotch against her lips, breathing deeply the scent of his cock and balls on them. As the throb along the slit of her cunt became more pronounced, she parted her lips and sucked gently at the shorts, imagining she could taste his balls. Lifting her dress, she pulled the elastic waist of her panties from her body, and ran the shorts into them, pressing the crotch against her swollen clit.

With them bulging in her panties, she returned to her room and lay down on her bed, one arm over her eyes, remembering the first time she had done anything like this.

She had been very young when she lost her mother, but she had tried to take over the household chores, and managed quite well for her age. However, the loneliness of her father was something she could not handle. She knew he missed her mother in a special way that she could not help him with.

She first discovered just how much he missed her mother one evening just as it was getting dark. She caught her father jacking off on the back porch of the house. He had been standing at the edge of the porch, his cock in his hand, sliding his fist up and down it. Karen had peered around the corner of the house, watching him. His cock had seemed enormous to her young and still innocent eyes, and she had become fascinated with it. She became even more so when she saw him gush a thick juice from it.

That very night, late, she had slipped into his bedroom, and removed her gown, climbing under the sheets with her father, squirming her hot little body tightly against his, her small hand sliding down his stomach to clutch his cock. Her father had came awake, startled, and sat up, but Karen had such a grip on his cock that he fell back and groaned as her hot little hand began to slide up and down. Her fingers had hardly fit around the thick prick, but she accomplished what she set out to do.
