A few years after I got married my mother-in-law caught me masturbating. She wasn't in the least embarrassed or upset. She encouraged me to finish and gasped at the huge load of cum I shot, then quickly exited the bathroom. Later that day she pulled me aside and told me how exciting it was for her to see me cum and that she wouldn't mind "catching" me again.

Over the years we have shared her cum fetish many times. Often she will take off her blouse and have me cum on her bra and tits. I have often cum on her face and she especially likes it when I cum in her hair. At family functions she will take off her panties and leave them hidden in a bathroom. After I cum all over them she puts them back on. It's our little secret.
