"Lie down, Brother!" she whispered, spunk spraying from her lips as she spoke.

Chuck grinned and got down on top of the trap door, still maintaining security – not realizing that barring the door did no good now, because their mother was already in the attic and looking on with glee.

He lay on his back, his cock towering up above his groin like a rocky spire and his cumbags steadily filling up again at the base of his prick.

Frostie stood up and removed her skirt.

She wasn't wearing any panties.

Obviously, she had known what they would be doing and figured it would have been silly to put on a garment that she would be removing again so soon.

Naked, she stepped across her brother and stood over his prone form.

He gazed up into her groin.

Their mother's attention was focused on that foaming fuckhole as well.

Mother and son were both licking their lips.

Frostie's pussy was gaping open in a wide oval. Her coral pink cunt-lips were unfurled like a flower and her cunt-slot was full of juice.

Her clit was standing out in a little taut knot, as if echoing her nipples.

Cunt-juice was pouring into her crotch, turning that groin grotto into a steaming swamp. Ribbons of the gooey stuff unwound down her inner thighs.

She gracefully sank down to her knees, straddling her brother's eager, upthrust head.

Chuck was shooting his tongue out even before he had made contact with his sister's cunt. He was staring at that juicy delicacy like a hungry child looking into the window of a candy shop.

Rachel was having trouble controlling herself.

It had made her plenty excited to sec Frostie suck Chuck off and drink his jizz, but this return engagement was stimulating her in two ways.
