Her reading of those explicit books had given her a fine knowledge of the ways of men and women and she had already attempted to translate some of the theoretical knowledge into practice. She would have succeeded too, except that she miscalculated the extent, to which she had already aroused Doug Matson, the youth whom she had selected to her accomplice in the project, and brought him to a climax as she was attempting to get his prick stuffed into the lightly fuzzed lips of her pussy. The flood of hot, sticky come which had emitted from his cock that afternoon had fired her desires, though, and she had wanted him to fuck her properly at the first opportunity.

Sue exchanged a meaningful look and a lewd grin with her younger sisters, both of whom were almost exact copies of herself, except that neither of them had the same pronounced bustline as she and neither had anything like the growth of downy, blonde fuzz on her pussy that Sue had. She lifted a forefinger to her lips in a gesture for silence and tiptoed toward her parents' bedroom. By maneuvering carefully she managed to peek through the open door. The sight caused her almond-shaped eyes to widen with astonishment. For a moment she imagined that her father had, for some strange reason, put on one of her mother's wigs before he had started fucking her; the male figure she saw atop her mother's heaving body had dark, almost black, hair, a far cry from her father's sandy thatch. She blinked and looked again, uncertain now. At that moment a cry from her mother made it clear.

"Omigod, Lew, you're making me come again! Annggghhh! You stud-pricked bastard, you just can't stop fucking! Owwww! Unnggghhh!"

It was at that precise moment that Sue realized that her mother had herself a lover, a day-time boyfriend.
