The Boat Is Rocking: Does This Mean I'm A Cuckold?

My wife and I had been together since we were 18. Now in our early 30s, she's still the innocent girl I've always loved... at least that's what I thought. When we board a ship that doubles as a hotel, a larger, more attractive man promises me he'll be taking her innocence from her. I thought I knew her, but when she begins spending time with him, I find myself watching as my wife becomes another man's piece of ass.
