It works really well

Not an hour later, Lauren comes home. "I´m home!"

I hide in the bathroom and wait for her reaction. I hear her come up the stairs, turn left into the bedroom, then I hear her undress. "John! Is this for me?" "Yes honey!" I call back, pretending to be getting ready. "Just put it on and I´ll be right with you soon!"

I wait for a few minutes, then exit the bathroom to our bedroom. Lauren has put on the hood, and is otherwise naked, sitting on the edge of our bed. I pull out the collar. "Now I´m just gonna put a collar around your neck so the hood doesn´t slide up and off, okay?" She nods, trusting me. I place the collar around her neck and buckle it on. Her breathing picks up. "John, I don´t know why exactly, but this is getting me exited." She reaches out and finds the bulge in my pants. "Let me get that for you, Sir."

Looks like the collar is already starting to do its work. Seeing as she´s starting to discover her submissive side, maybe push on a bit further?
