Her lips were close to his ear, and she began to whisper. "Come, Bob. Let it go, baby. Don't try and hold it back. Let yourself come."

And come he did.

Susan stopped jacking her son, wrapping her palm about the smooth head of his cock, feeling the boiling come juice splash into her palm. She mewled softly, her cunt starting to convulse in a sweet orgasm. She continued to hold his cock after he came, watching the strings of come juice float through the swirling water. She stabbed the tip of her tongue into his ear, then giggled in a lewd way.

"Better?" she whispered.

Bob nodded, a grin spread across his young face. Susan tucked his cock back into his trunks, and they sat close, holding hands. Susan glanced again at Billy and Pamie, wondering if they knew what he had done. But they weren't paying any attention to her and Bob. Again she looked between the slender thighs of her daughter, running her tongue over her lips.

"Did you like that, Bob?" she whispered in her son's car.

Bob nodded, still grinning.

"Mmmm, so did I," she admitted, and pulled his hand onto her thigh.

She spread his fingers out on her thigh and moved his palm up and down. A shiver shot through her as she pulled her son's hand between her legs. Before she could change her mind, she opened her legs very wide, and pulled her son's palm into her crotch, pressing hard upon her cunt.

Bob gasped again as he felt the heat of his mother's cunt burning through the very thin fabric, so hot he thought his palm would blister. He looked at his mother, and Susan was grinning lewdly at him.

She drew his palm up and down her crotch a few times, twisting her hips. "Ooooo, nice," she murmured. "Do you like to feel me, baby?"
