At her daughter's wedding, the mother is secretly fondled by a wedding official. Two days later the mother visits the wedding official about the sex game he had played with her body. She agrees to let him consummate the fondling but soon finds that three of his friends are joining him in completing the sex game, all three ways.
He lost his beloved sister, the only person he ever loved or who loved him, followed by both of his parents. He rightly blames the District Attorney, and the drugged out vagrant bums who killed her and then were allowed to go free. With no reason to suppress his inner demons, he seeks revenge on the guilty.
This story was told to me by a man who discovers that his wife likes cocks much larger than his own. He relates how he learned this by watching, from hiding, as she is gangbanged while they are on vacation.
