SPRD-931 - Way better than my wife... The hidden temptation of my 40-year-old mother-in-law

I've had my eyes on my mother-in-law since I got married. My sex life with my wife is dead, and when I saw her mother-in-law's underwear in the laundry basket, I lost my mind. I got caught sniffing it, but instead of being mad, she started touching me. Forbidden pleasure with my mother-in-law while my wife is away is just too good.
