Keep it in Family

I am 72 and my wife is 67, we are still very active with each other, anyway married my wife
she was a divorce with three kids. before we were married I was living with my sister and her
and children ,sis is three years younger than I am. when we were teens we would mess around ,
and by the time we were 12 and 13 I was having sex with her. Now, my wife is still very into sex
and I use the last week end we were laying and doing our normal foreplay, like me rubbing her pussy
and she was massaging my cock,as we both began to get more horny, we talked about our sexual
past a lot, she admitted that her brother had taken her cherry,so I admitted to her that I did the
same,anyway my sis lives not too far from here ,she is a widow and visits often.My wife all of a
sudden asked me if I would screw her again if she was here. I said sure.So we called her over.we
started talking about our younger years. my wife asked her how her sex life is,sis said its been a
long time. My wife said, "I know about you and your brother's past" but thats ok,wife continued
to tell her about me using a pill that makes it hard and keeps it hard for a long time, sis said Wow!
I bet that is so good, I said would u like to find out, she said why not.So we went to bed that night
all three of us as I layed and fingered both women I became rock hard, I rolled over on sis and
filled her full of my juice, pulled out and did the same to my wife, we really had hot sex that night and
look forward for more to come....(you never too old for sex)
