That her son and nephew were doing what she had done with her brother to the exquisite little creature who was her niece sent a hot, wet kind of fire through Mandy's pussy, causing her clit to bulge excitedly. She tried to visualize her young son and nephew, cocks hard, fists pumping, while little Julie leaned back to catch their cum-loads in her mouth, her slim legs spread open, her sugary pink cunt wet and exposed.

Her ass writhed with the mental pictures, her cunt vibrant. She felt her son's hands caressing oil along the backs of her thighs now, and her breath caught. His hands felt so good on her thighs, so very good. He was moving them slowly, up and down, from her knees to the cheeks of her ass, but never quite touching the swell of her ass. Then his fingers were running up and down the insides of her thighs, and Mandy's cunt was responding with wet heat again.

Forgetting about the crowded beach, she turned and glanced toward her son, seeing that he did have a hard-on. His cock pressed at the front of his trunks, and she could see a small movement as it throbbed. Derick was sliding his hands up and down his mother's satiny thighs, almost panting with excitement. His excitement drove him, and the edge of his hand moved a little too high along the inside of her thigh. Mandy gasped as she felt her son's finger press at the tight crotchband of her bikini, then jerk away quickly.

Mandy's breath was hot as she slipped a hand from under her head and moved it along her side, then onto her son's thigh. She held her breath as she slowly stroked his flesh. Derick was staring at her hand, his resting on her thigh. Mandy couldn't resist. She had to touch her son's hard-on. She didn't even try to resist… the tips of her fingers touched his cock, the shaft of his cock, and Derick gasped loudly, his hands jerking off her thighs. Mandy, too, pulled her hand away.
