Pamie couldn't breathe. Billy's cock cut her air off as he pressed into her throat. But she shivered again and twisted her lips at the base of his cock. She slipped her hand between Billy's thighs, stroking his balls, cupping a cheek of his ass.

"Suck it, baby!" Susan urged, arching her crotch into her fingers. She now was fucking herself with all four fingers, gasping in erotic, voyeuristic delight. "Ooooo, suck his hard cock, Pamie… suck it! Fuck him with your pretty little face!"

"Mmmmmm," Pamie moaned as she drew her lips back, keeping her mouth tight. She slipped her lips off his cock, but thrust her tongue out, flicking it up and down on his piss hole, then circling.

"Like that, Mother?" she asked, her voice throaty in a childish way. "Is that the way?"

"Oh, yes!" Susan growled.

"Remember, Billy," Pamie said. "Don't come in my mouth."

"I won't," he promised.

Pamie sucked his cock back into her mouth, but she didn't take all this time. She darted her lovely little face back and forth, sucking, her creamy cheeks sinking inward as she pulled back, ballooning out as she went forward. She started slowly, allowing her mouth to become accustomed to the size. Billy's cock seemed so hard and thick, stretching her lips until she wondered if they would split. The fuck juices dripping out of his pies hole coated her tongue, and she swallowed a couple of times, finding the taste not bad at all. She beat her fist faster on Bob's cock, holding the head against her pink, hard nipple.

Susan began to make soft, sobbing sounds as she watched, her tongue racing about her lips hungrily. Her naked ass churned almost violently as she fucked her fingers in and out of her juicy cunt. She wanted to grab Bob and pull his cock into her cunt, fuck him frantically as she watched her daughter sucking Billy's cock. But at the same time she wanted to watch them, all three of them.

"Ooooo, suck it, suck it!" she whimpered. "Oh, honey, if I had a camera! You don't know what it's doing to me, watching you, your mouth stuffed with your brother's cock!"
