At 38 years old, I'm a company employee, and when my wife gave birth, her mother came to help us out. My mother-in-law is 55 and currently a widow. She's kind and gentle, and since she married young, she's close to my age. I feel guilty toward my wife, but I became completely obsessed with her alluring, voluptuous body. During my wife's hospital stay, my relationship with my mother-in-law took an unexpected turn, and I'm still surprised by what happened. I keep wondering whether it was her loneliness or her own desire that led us here. This affair has brought a significant change into my marriage.
