I observe another man's ejaculation into me while being a cuckold

In this tantalizing tale, I find myself in the unique position of witnessing a man's climax inside me, while being the unwilling participant. My wife, a strong-willed woman with a penchant for the peculiar, has taken it upon herself to introduce me to the world of cuckoldry. As I lay there, helpless and resigned, I am forced to endure the sight of another man's release, his warm, sticky substance filling me to the brim. The sensation is both surreal and unnerving, a strange mix of pleasure and revulsion that sends shivers down my spine. I can only hope that this bizarre encounter will come to an end soon, but as my wife continues to revel in her twisted desires, I fear that I may be in for a long and painful night. This is a story of domination, submission, and the unbridled exploration of the human body's darkest fantasies.
