With a single exception this was the game plan at the Molly and mick manse in River City: Mistress would sometimes have a sleepover "guest". Her devoted slave would occupy our daughter's room next door (by then the daughters had flown the nest). The walls were thin. I was typically caged, to avoid any unsanctioned self abuse as I listened in to their enthusiastic coupling. One thing became all too obvious: Jay (and the occasional "other") could induce much more enthusiastic sounds from Mistress than I could with my "work-a-day" cock. Was she exaggerating her responses for my benefit? Could be, but I doubt it.
Our typical husband / wife sex, still a daily morning ritual, was more gentle and loving. Yes, Mistress would be lavished with a few cums/session. Still is. But there was/is no athleticism involved. No rhythmic slaps of flesh on flesh, and endless moans from Mistress. Of course, all of this listening in could be enticing, exciting and frustrating for a caged slave.
But once the lover de jour went on his way - typically after I served him coffee in the morning - slave always got his turn, even though Mistress was frequently tuckered out and tender.
She was and always has been an indulgent Mistress.
