40 year and still going
I was going with my gf for 4 years and I got married 37 years ago and my gf mother was 44 when we first meet. With in a year her mother love swimming nude when her husband was not around in her pool. My gf also love swimming nude in those days.
With in a year of meeting my further wife her mother and I was have s** on the side.
After our wedding any time I call around and my father in-law was not there we have full on s** with no restriction.
To day my mother in-law is 85 and I'm 60 and I visit her in her own unit at the retirement home and as she lost her husband 10 years ago she has become more sexual than ever.Yes I still using my manhood in her as she does want to stop and it got to the stage I have s** more with my mother in-law than my wife.
She told me that when she first met she want my manhood and can not explain why.
