Rusty pumped her tightly stretched lips up and down over Paul's upstanding cock, her lewd tongue lapping madly. Rusty mewled and grunted impatiently. She was eager to have her brother cum in her mouth. She wanted to taste his salty juice as it filled her mouth and poured in slippery wads down her throat. The low sounds of her gluttony were well muffled by the mammoth bulk of cock that slammed into her wet mouth.
Then suddenly, Paul cried out in delight and arched his back off the bed, shoving the knobby head of his prick tightly into the back of her throat us he sensed the eruption of his pent-up jism. The huge gob of cum blasted against the roof of Rusty's mouth and her fingers tightened around his large, heavy balls.
Although it was his second cum in less than an hour, Paul's jism was as thick and abundant as the first time. His nuts churned and twitched, pounding a steady flood of hot jism into his sister's sucking throat. They both thought he'd never stop cumming.
Rusty's flushed cheeks puffed out and relaxed rhythmically as she strove to swallow fast enough to keep from choking on his madly splattering cream. Paul's hips continued to pump his spasming cockshaft in and out of her flooded mouth. The cumjuice in ha mouth was leaking out and cunning down her chin and throat.
At long last Paul stopped spurting into Rusty's mouth and the four of them fell limply apart, lying in huddled heaps of sweaty, quivering bodies.
An hour later, Rusty was squealing hastily as bounced up and down on Ken's stiff cock, jamming his thick shaft into her snug pussy with such force that her cunt juice squirted out with each hard, downward thrust.
While half her mind was concentrating on making herself cum under the steady pounding thrusts of her father's thick cock, the other half was busy making plans for the future.
Now that she had her whole family fucking and sucking together, her next move was obviously to expand her circle of bedmates. Offhand, she could think of at least a half dozen young studs at school who would be only too willing to shove their cocks into her sweet young pussy. Or, for that matter, her mother's.
And then there were the girls. There were at least three or four adorable little pussies, all ripe and ready for a stiff cock or a juicy tongue.
Rusty giggled merrily as she felt Ken's fat cock give a sudden jerk against the sensitive walls of her fuckhole. Actually, she hadn't expected him to be able to get it up again so soon after that wonderful four-way daisychain. But a short nap and a quick snack of cold sandwiches, plus a little mouthing and tonguing from her, and he was once more hard and eager to fuck.
All thoughts of her friends at school left her sex maddened brain as Ken's fat, knobby cockhead pounded into her, spurting wads of hot, gooey jism deep into her cunt.
After Ken had stopped cumming, Rusty slumped down wearily over his body, grinding her swollen, stiff-nippled tits against his chest and hugging him tightly around the neck. A soft, cooing whimper of joy reminded her of the couple on the other side of the bed.
Rusty and Ken turned their attention to where Valerie was lying in a sixty-nine position over her son's body, lapping and sucking on his hard, thick cock. Paul's upturned face was snuggled cozily into her juicy crotch, his long, pointy tongue darting and drilling deep into her frothy cunt.
Ken smiled broadly as he watched his wife and son suck each other off. He hugged Rusty from behind, cupping her upjutting tits in his hand. She sighed happily and leaned back against him, her mind drifting back to the subject of which of her friends at school would be most suitable for her family's kind of fun.
