This all started years after I had been married. My mother in law, Dee, lived in a different state and wasn't around much, so my earlier memories of her were vague. Although I knew she was a beautiful promiscuous blonde. At times I'd catch a glimpse of her ass, try and get a cleavage view, but she didnt have much there so it was almost pointless. Her and my wife Marie's body resembled each other's closely.
Her family was always very affectionate in greetings and goodbyes and often would try and peck kiss me on the lips. I'd usually just turn my head and that was that.
Recently I stopped resisting that, on Dee in particular, I'm 51 now and she's in her 70's (looks all of maybe 50ish) and the first time I allowed her to kiss my lips, she kissed me before leaving and it was very stimulating to say the least and i felt a stirring in my pants, probably because I haven't felt another woman's lips on mine in years. Since that time, she actually will take every opportunity she can to kiss me, and mostly when Marie isn't around. Marie is my wife, by the way.
Dee lives alone in a small house in town a few miles from us.
