"No, she'll catch us!" Julie wailed, but she made no effort to push her brother's hand away from her cunt. "Ooooh, Tommy, that feels good! Aiihh, I like your finger up my cunt, Tommy!"

Susan's pussy throbbed powerfully as she gazed at her children. Her eyes watched with burning desire as her son pumped on his cock. She could see his balls swinging, and there was not a single hair on them that she could see. She wished she could see Julie's cunt, with Tommy's finger stabbing into it. She leaned against the doorjamb as she watched, her legs feeling weak. Her tits became swollen and her nipples burgeoned out like twin peaks.

"Ohhh, you're gonna make me do it, Tommy!" Julie squealed. "Oooh, I'm gonna come!"

Julie's head was thrown back and her hips writhed and twisted excitedly. Susan's eyes blazed with steaming desire as she watched. She felt the strongest urge to let them know she was there, and to go to them and take her son's cock in one hand and her daughter's cunt in the other.

"Oh… oh… ohhhh! Tommy!" Julie shouted. "I'm coming! Ohhh, fuck it for me I'm coming!"

Susan moved out of the door and waited until they had regained their composure, then returned to her canvas. Tommy and Julie were sitting and kneeling there as if nothing had happened between them. Susan smiled, thrilled by what she had seen for the second time.

She sat back on her high stool, bringing one heel up. As she dabbed with her paints, her mind filled with erotic images, and she did hot realize that her son and daughter were peeking at her.

Tommy and Julie tried to hold back their giggles as they peeked at their mother. With that one knee up and spread outward, they could see her hairy cunt. Tony's cock grew even larger. Each time Susan looked at them, they had been quick in averting their eyes. But now Susan saw her son's cock saw how hard it was, with glistening moisture on his piss hole; and her pussy was throbbing and her tits were swollen. She was breathing fast with steamy desire. She sat on the stool, her painting forgotten. She was hardly aware that she was staring at his cock. She only knew that it was a cock and that it was very hard and she was bubbling with intense desire.
