They were lying on huge towels near the surf. Again, Mary and Carol were in bikinis, the hot sun broiling their flesh. Steve sat cross-legged hear his mother, rubbing tanning oil into her creamy flesh.

The feel of her son's hand on her skin made her tingle in that delicious way. However, because Carol was nearby, she watched him closely. Steve might try to put his hand somewhere it didn't belong.

"Where is Tom?" Mary asked, drowsy in the sun.

"Who knows?" Carol said. "Who cares, too? He can get into his own mischief. Me, I'm going to see if I can open up a conversation with that hunk over there."

Mary had hot known Carol to be forward, despite the way she spoke at times. Perhaps it was the sun, the total atmosphere. Whatever the cause, she watched Carol get to her feet and stroll slowly toward a man who was sitting on the sand and drinking beer. Carol's bikinied ass swayed cutely, she noted, as did Steve.

"You like that, baby?" she whispered.

"Like what, Mom?" he came back, pretending innocence.

"The way Carol's ass moves," she teased.

"Aw, Mom." Steve dropped his eyes, and a flush came over his face.

Mary placed her hand on his thigh, moving her palm gently as she whispered: "I'm just teasing you, Steve. I know Carol has a cute ass and you'd be a fool not to look at it."

She trailed her fingers toward the crotch of his trunks, and gave his cock a brief prod with one fingertip then drew her finger back before someone saw.

Steve began to rub at her thighs, smearing the light coating of oil into her flesh. Mary closed her eyes, sighing happily, enjoying the feel of his hands on her body. She could hear the shouts of others on the beach as they enjoyed this hot day. The gentle surf was calming, and she began to doze.

Just before drifting into sleep, she felt her son's hand move along the inside of her thigh, then his finger was tracing the slight bulge of her cunt inside the bikini. Slitting her eyes, she watched his expression change. His face was glowing as he studied her body, his lips parted slightly. Dropping her gaze, she saw the way his cock was lumping up in his trunks. She squeezed his knee.
