"Not mother," Julie's voice replied. "She's always so involved in painting; she never pays any attention to what we're doing."

"I like seeing you that way," Tommy, said. "Tomorrow, why don't you hold your legs open farther? I could hardly see your cunt this afternoon, Julie."

"Okay," Julie giggled. "I'll make sure you can see my pussy real good tomorrow. Right now I'm so fucking hot, Tommy! Come on let me jack your cock! You can finger fuck my cunt, too."

Susan's breath was burning in her lungs as she listened to her children. Her tits were quite swollen and her nipples pressed at her gown. Her cunt was twitching hotter than it had in years, and the inside of her legs was becoming slippery. The door to her daughter's bedroom was not closed all the way, so she peeked through the narrow opening.

Julie and Tommy were sitting on the bed. Her daughter was wearing a shorty baby-doll gown, but she was naked beneath it. Tommy was in his pajama bottoms, but his cock was standing out throbbing in hardness. Susan saw her son sprawl back on the bed while Julie got onto her hands and knees.

Julie took hold of her brother's cock and began jacking up and down. Susan saw her son slip his hand between his sister's thighs, and then his finger slithered into the wet, hairy pussy.

"You're sure hard tonight, Tommy!" Julie giggled softly as her fist pumped his prick. "You really get hot when we pose with hardly any clothes on, don't you?"

"You do, too," he said, working his finger in and out of her cunt. "Your cunt was wet, Julie."

"It sure was!" Julie agreed. "I bet mother never knew your cock was hard, either!"

Susan's eyes were almost unfocused as she stared at her children through the slit in the door. She could see her daughter's hand rubbing Tommy's cock, and it sent a thrill of hot pleasure racing up and down her spine. Her steaming pussy began to throb between her thighs, and her clit seemed ready to explode. She turned her eyes to her daughter's round, firm ass waving about in the air. The cheeks were fully revealed because Tommy had shoved the gown up to her waist and Susan could watch his finger plunge in and out of Julie's surprisingly cute pussy. There were moist sounds coming from the room, and Susan pressed the heel of her hand hard against her burning cunt.
