"You'd let me look?" he asked, his voice thick and shaky. "You'd really let me see you, Mom?"

"It wouldn't be fair if I didn't, would it?" She hugged him tightly. "I mean, if you let me watch you jack off, it would only be fair to let you watch me, right?"

"Gosh, Mom!" Derick gulped, his young body shaking.

"Do you want to do it with me?"

Derick nodded his head vigorously, rubbing his cheek on her rigid nipple, his arm squeezing her waist.

Mandy closed her fingers about her son's cock, squeezing it inside his trunks with an excited gulp of pleasure.

"Let's do it now!" she said, pushing him away. "Let's do it right now, baby!"

Derick's eyes were hot as he looked at his mother's passion-contorted face. "You really mean it, Mom?"

She nodded. "Push your trunks down, like in the car, and jack off for mother."

As her son gazed at her, she leaned back on the couch, spreading her legs wide, the narrow band of her bikini stretching over her cunt, her tits lifting sharply. She gazed back at him with slitted, burning eyes. One of her hands came up to curl about a tit. She shoved her fingertip into the halter, and slowly pulled it downward. Her nipple came into view, and Derick groaned as he looked at it. But Mandy covered her nipple, sliding her hand down her stomach to the edge of her bikini. She pushed at the fabric and exposed a soft line of thick pussyhair to her son's eyes. Sliding her finger down the front of her bikini, she traced the slit of her cunt, then very slowly pulled the crotch to one side, giving her son a very brief glimpse of her cunt.

"Now…" she purred. "You know I mean it, honey. Shove your trunks down and jack off for mother!"

Derick was so excited to get that quick peek at his mother's stiff nipple and cunt, his cock was ready to burst from his trunks. He stood up, pushing them to his knees. His cock jerked upright, making a slapping sound against his stomach. Mandy gurgled in delight as she gazed at him, her eyes hot on his young balls and very stiff cock. She saw a small mat of wiry hair at the base of his cock, but his balls were hairless. They weren't really big balls, but looked deliciously full.
