John arrived home to his suburban house after a tedious day's work to find the place apparently deserted. His wife, Helen, also worked and was often stuck at her office later than he but the twins ought to be home from school by then. He was perplexed and moved through the house silently -- as was his habit -- and up the stairs. Glancing into Jack's room he found it empty but from Amber's room down the hall he heard the faint rustling of activity. He peered through the agape door of his daughter's room to see an oddly perfect triangle of eighteen-year-old bodies, with Jack and Amber's tongue-entwining kiss forming the apex and Amber's best friend Candi as the base, Jack fucking her pussy while she ate out his little girl.
Stiffened, John stared bewildered by his children's hijinks with the neighbor girl. Jack and Amber were really into each other, not as siblings or sex buddies but as full-fledged lovers with Candi playing the enviable part of their latest conquest. John played with himself as he watched them; his daughter's blonde hair hanging down to her breasts, Candi's long legs wrapped around his son's ass, which was tight and delicious. Jack's whole body was nubile and taught, a perfect complement to those female masterpieces with which he was engaged.
It occurred to John to strip off his clothes and stride into the room. He foresaw the girls shriek and try to hide their nakedness with pillows while Jack stuttered out an explanation. He would hear none of it, but grabbed that Candi girl by the hair and shoved his cock into her mouth. While she sucked him off, he would explain to his children the new arrangement and they would fall into his arms and kiss his cheeks. They would then lower their attention and run their hands through the hairs of his chest, teasing his nipples with flicks of their tongues. He saw himself kissing Amber and feeling her shudder from the fresh experience of a man with a mustache. She'd beg him to eat her out with his tickly lip, but he'd tease her and tell her Jack would get it first. Then he'd bend his own boy over the bed, while Candi and Amber watched on and played with each other, and shove his tongue up the boy's ass.
Jack was moaning at his father's touch and begged to be fucked in his virgin ass, but daddy can't play favorites. So John leaps over onto the girls and buried his face in their ample cleavage. He feels the wetness in his daughter's crotch and positions himself to fuck her. Candi lusts for the older man fucking her girlfriend and kisses him with zeal while Jack licks his father's balls from behind as they slap up against his sister.
