Pretty sure I read this in Loving Wives a little over a year ago. Written from the husband's perspective, he has an acquaintance/co-worker/fellow club member? (referred to as the CAD for my reference here), whom begins by bragging that he can seduce our man's wife. First humiliation clue is the cad leaving her bra in the husband's office. Then her panties in the locker room. Eventually the wife gets passed around by the instigator/CAD in this story to his friends, gets hooked on drugs and group sex. Somewhere along the line there is a sting operation spearheaded by the husband which gets the Cad and gang arrested and frees his wife from their clutches. They go to counseling and things become normal for a while, but the wife still craves group sex. The hubby goes along with her on some group sex adventures for a while, but ultimately can't stomach the situation and divorces her. They remain in touch for their children but the kids pass along the fact that their mother still disappears for a long weekend about once per month. I've searched cuckold, group sex. loving wives, cheating wives, adultery, humiliation, revenge, tags etc. without any success. Would appreciate if anyone recognizes the story or author. Thank you!
