She doesn’t know that I’m standing at her bedside, naked and erect, as she sleeps. It’s 2 AM. My wife is asleep in our bedroom, unaware that I am not beside her. I slowly stroke my cock and step closer to my sister in law.

Boldly, I allow my dick to nearly touch her lips. As I masturbate, I close my eyes and imagine that I am fucking her. What if she awakens? What if my wife comes looking for me? The excitement of it all is intoxicating. My cock throbs. I want... no, I must come.
