"Ahhhh… uhhhh!" Derick groaned, then his cock gushed cum.

"Ooooooh!" Mandy breathed as she saw the kid's thick jism spurt high into the air. It arched and landed on her thigh, making her squeal with pleasure. Time and again, Derick spewed his creamy cum, his balls writhing as his fist kept pounding up and down. "Ahhhh, lovely, so lovely!"

Finished, Derick squeezed his cock and pulled up on it, bringing the last of his cum to his piss hole. Mandy watched it run over his gripping fingers and down onto his balls.

Derick stood there, his young chest heaving up and down as he struggled to breathe, still gripping his cock. Mandy's eyes smoldered with moist heat as she rubbed his warm cum into the flesh of her thigh.

"Was it good, Derick?" she asked in a whispery voice. "Wasn't that better than jacking off alone?"

"It sure was, Mom!" he panted.

"Do you still want to watch me do it, too?" she asked in a low, husky voice.

"Yeah!" Derick gurgled, his eyes glazed.

Mandy slipped her fingers into the elastic ribbons of her bikini at her hips, and pushed downward. She stopped when the soft curls of her pussy hair showed, and twisted her hips for her son's delight. She raised her ass, easing the bikini bottoms past it, and to her knees. Derick was hardly breathing as he gazed at his mother, his eyes fixed upon the thick triangle of her cunt hair. Mandy lifted her feet to let her bikini bottoms fall away, then slowly spread her long legs.

"Ahhhh!" Derick moaned as he saw the pink slit of his mother's wet cunt, framed by the soft dark hair. He saw her clit push up from the slit, watching it vibrate with heat.

Showing her cunt to her son sent wild, shivery excitement through Mandy. She held her legs wide open, caressing her thighs with her hands as she saw his cock starting to become hard again. She opened her pussy with her fingertips, lifting her ass, grinding slowly. Derick stared at his mother's cunt as she began to slowly rub at her swollen clit.
