Tracy paused to admire her friend for a moment, before she announced her presence. Tracy had never made it with another girl, but she had thought about it a great deal and, when she did – usually while playing with her pussy – she generally thought about Jennifer.

Jennifer was every bit as nubile and sexy as Tracy, but in a different and nicely contrasting fashion. She had blonde hair, worn curly and tumbled, big blue eyes that could look both innocent and sultry, and a shapely figure that had certainly inspired many creamy wet dreams and hand-jobs among the local lads.

Tracy wasn't the only one admiring lovely, blonde, bikini-clad Jennifer at the moment.

Eighteen-year-old Joe, tall and athletic and pubescent, had also been staring at his kid sister and getting a booming hard-on in the process.

Joe had been screwing his pounding fist while entertaining incestuous thoughts for some time now. The boy figured it was wicked to lust after his sister, but what the hell – that only made him cum more. Joe lurked around the house, constantly hoping to catch a glimpse of the sexy sibling in a state of undress, changing her clothing or taking a shower or sunbathing topless.

Joe, at the moment, was sitting in the arbor across from the pool, concealed in the leafy shadows, his eyes glued on Jennifer's trim body and his prick thundering in the confines of his tight jeans.

Soon necessity would decree that he haul his cock out and empty his balls by hand, he knew, but he was waiting as long as he could, even at the risk of creaming his jeans, in the hopes that his sexy sister might decide to remove the top of her bikini so that he could beat his meat over the mouth-watering sight of bouncy tits.

Lying on the ground beside Joe, the family dog, a big German Shepherd, was also regarding Jennifer with a certain interest.
