"Naw – I saved my load, Sis," he grunted.
"Goody! I didn't finger-fuck myself, either. I figured we could sneak up here."
"Yeah!" he enthused. "You wanna do me first, Sis, or shall I do you?"
Frostie considered for a moment, licking her lips in a speculative and suggestive fashion.
"I'll suck you off first, Chuck," she decided. He grinned and started to open his fly. Frostie sank gracefully don on her knees before him, both on top of the trap door.
Holy shit! thought their mother. Those naughty, naughty kids are going to give each other head! My God!
Should she stop them?
Like hell she should!
Rachel was going to watch.
CHAPTER TWO
Chuck whipped his zipper down and his formidable cock came bouncing out like a meaty shock absorber. Grunting, he reached into his fly and hauled his balls out, too. His prick loomed up in his sister's pretty face.
Their mother gasped softly when she saw how huge and hard her son's prick was, how loaded his balls.
His cockhead was a bulging slab of flushed purple meat, already frothy where preliminary fuck juice had come oozing out of his pisshole. His cockshaft was long and thick and gnarled up the underside by a dark, fat, throbbing vein. At the base of his prick, his balls were as big and fat as juicy melons.
Her son's cock looked as huge as the rubber cock that was still stuffed up her cunt, Rachel thought – and a hell of a lot tastier!
Frostie was licking her lips as she gazed at it, and the girl's nostrils flared open as she inhaled, breathing in the musky, gamy fumes rising from his meat.
Her blonde head swayed about as she fob lowed the jerking convulsions of his cock, and her blue eyes turned inward as she focused on his slimy cock-knob.
