"Ohhh, God, baby!" she moaned. "Jack it off for mother! Grab it and pump it, Derick! Ohhh, baby, jack that beautiful thing off and squirt it for me… show me how hard you can come, darling!"

She leaned back on the couch, legs spread wide, gazing at him as he closed his fist about his cock and began to stroke up and down, his hips thrust forward, trunks caught at his knees. His gasps and panting breath excited her just as much as what he was doing for her. Her cunt bubbled wetly, throbbing inside her bikini. She clutched her tits with both hands, squeezing them as she stared with fiery hunger at her son's cock. The juices seeping out of his piss hole made her mouth water, and she swallowed noisily, writhing her ass on the edge of the cushions, opening and closing her long, shapely thighs.

Derick stared at her bikini-clad body, ramming his fist up and down on his cock frantically.

"Beautiful!" Mandy hissed. "So beautiful, Derick! You have such a nice one… long and swollen and hard! Come a lot for mother, baby! Squirt it way out for mother! I love to see a boy come… come hard and come a lot!"

As he jacked off, Derick watched his mother open her legs wide, and begin to hump her ass up and down, fucking at the air. The soft hairs of her pussy showed from the edges of her bikini, exciting him further.

"You're making me so wet!" Mandy gasped.

It was true, he saw. Glistening wetness seemed to be on her inner thighs where the crotchband hid her pussy. Derick licked at his lips as his fist pounded up and down, his hips jerking in a matching rhythm.

"I think… Mom, I'm about to do it!"

"Yes, baby!" she squealed. "Come! Squirt it out! Splash that hot jizz for mother!"
