"Kiss it, Pamie," she hissed. "Kiss Billy's cock, baby."

Pamie looked at her mother from the corner of her sparkling eyes, pursed her lips, and kissed the tip of Billy's cock. She brought her other hand up, closing her fingers around the hard prick shaft, and then she was jacking both of them. Pamie rubbed her ass back and forth on the bench. While jacking her brothers' cocks, she kissed along the sides of Billy's, keeping Bob's piss hole pressed against her nipple.

Susan watched Pamie's pink, moist tongue slip from her lips and lick along the shaft of Billy's cock. Her own cunt bubbled wetly as her finger stroked up and down the hairy pussy lips.

Squeezing Bob's cock upon her firm tits, Pamie licked at Billy's cock until his prick glistened wetly, but not once did she take his cock into her mouth. She dipped her head and lapped slowly at Billy's hairless balls, and the low mewls of her pleasure drifted to Susan.

"Suck, baby," Susan murmured. "Suck him… take his balls in your mouth and suck them! Let me see you suck his beautiful balls, Pamie!"

Pamie hesitated a moment, glancing at her mother, her mouth opening. Susan saw Pamie take a deep breath, then pull Billy's balls between her lips.

"Oh, God!" Susan moaned, thrusting her finger into her boiling cunt, watching. "I'm getting so fucking hot, just watching you kids!"

"Oh, wow, Pamie!" Billy gasped, looking down. "You never done that before!"

His cock pressed along his sister's cheek, starting to drip.

"His cock, Pamie!" Susan groaned, finger fucking herself furiously. She opened her knees now, holding them very wide, leaning back on one hand and churning her uplifted ass in time to her fucking finger. "Take his cock in your mouth, Pamie! Suck his cock, darling! Let me see you suck your brother's hard cock!"
