She pushed her face to Sally's, thrusting her tongue out and licking from one corner of her daughter's mouth to the other, then lapping the juice from her chin. Then she kissed Sally briefly.

"But he came in your mouth, Mother!"

"He's supposed to, Sally," Marla said. "When you suck cock, you suck it all the way. If you don't want the guy to come in your mouth, then don't suck him."

Bob was lying back, totally relaxed. His face showed his pleasure as he listened to his mother and sister. His cock still tingled, and his balls felt very good.

"He caught me by surprise," Sally said. "I didn't know he was gonna come off then."

Marla ran her hand over her daughter's firm, pointed tits. "Don't worry about it. You'll know what to expect next time."

Sally giggled and wiped, her mouth. "And next time I'm gonna swallow his come-juice!"

"I'm sure you will," Marla purred, sliding her hand to her daughter's cunt and finding it wet and hot. She worked a finger into the tightness, and Sally wiggled her ass. "Did it make you come?"

Again Sally giggled. "I came twice sucking his cock."

"Ahh, the sign of a good cocksucker," Marla grinned. "If a girl can come by tasting a cock in her mouth, you can believe she loves to suck it."

Bob rolled onto his stomach, feeling tired. He rested his head on his crossed arms, listening to his mother and sister talking as he closed his eyes.

Marla was on one side of him, Sally the other. Marla was looking at her son's ass, pleased at his nakedness. When Bob felt his mother's hand caressing his ass, he said nothing. He was drowsy, and his mother's hand moved so slowly and warmly on his body. It soothed him, and he was about to fall asleep.

Sally began to stroke her brother too, sliding her warm hands about his back, over his ass and his thighs. When Marla pulled his lop apart, Bob didn't resist. Marla and Sally played with his ass and took turns fondling his balls. He shivered occasionally, and was making slight movements.
