Mercy’s Threshold - Used, Filled, and Fed to Her Husband. Cuckold Heat Vol 1, #1

He didn't know what it would cost him-until she opened the first door. When Adrian and his wife receive an invitation to the Club of Red Doors, it seems like a fantasy. A secret. A challenge. But each door demands more from him: silence, patience, obedience. She walks through with confidence. He follows, stripped of control, reduced to a role-watcher, listener, servant. Her pleasure becomes public.
His needs are put aside. And what she takes in. she doesn't always keep for herself. Each act of surrender breaks him a little more-and makes him crave it more deeply. Inside the Door of Mercy, pride doesn't survive. Devotion does. You won't forget what happens behind the final door.
