Donna was indeed beautiful, despite what she thought.

She was mouth-watering, sensuous. The dark hair between her thighs was thick and soft, in the perfect shape of a triangle. There was a very thin line of hair growing up from the thickness to her bellybutton, making her appear erotic.

Timmy took it all in, his cock staining again inside cut-offs. His eyes burned with hunger.

"Turn around!" he said.

Donna looked at her son, and with a slight shiver, turned. Timmy stared at his mother's ass. Her ass was perfect, the most perfect ass ever. The ass cheeks swelled outward like twin bubbles, enticing with the inviting crack between them. She was a natural beauty, with a perfectly shaped body. With confidence, Donna could have perhaps become a highly paid model or actress. But she had no confidence in herself.

"Nice, Mom!" she heard her son say. "That's a very nice ass."

"Timmy, can I turn around, please?"

"Sure, turn around," he agreed.

When Donna faced her son again, she saw his shorts were hanging just below his hips. His cock strained out in hardness, the prickhead bulging. His balls hung low, exciting her so.

She new it was wrong.

"Come on," Timmy said, and turned from her.

Donna stood still for just a moment, seeing her son holding his shorts in one hand to keep them from falling. His ass was tight, small and hard. She swallowed, then, still naked, followed him passively.

"Get on the bed!" Timmy said as she followed him into her room. "Get on the fucking bed! Mom."

"Timmy," she said, a sob in her voice. "What are you going to do? Don't do what I think you are, please!"
