My wife (57) and I (60) have been married for 35 years. I retired in April. Our sex life is pretty good. She has a widowed Sister (59). Every Monday and Thursday I play golf and am gone most of the day. My Sister-in-law comes and spends the day with my wife. When I come home we share a bottle of wine and have dinner. My wife plays bridge every Monday and Thursday night and when my wife leaves I drive my Sister-in law home. I always kiss her goodnight at her door. The kiss started getting longer and one day I parted my lips. When she felt my tongue on her lips she started to respond and suddenly stopped, turned, said goodnight and went in. The next time she said we shouldn't be kissing. I said I think of you as my Sister. It's not that I don't want you to kiss me. It might lead to us doing something we may both regret.

That night in bed, I told my wife her Sister didn't want me to kiss her goodnight. She was afraid it might go further. She laughed and said, would you like it to go further? I said, I don't think I could cheat on you, but I guess the thought has crossed my mind. She's been really down in the dumps since her husband died. She's always saying how lucky I am. I'll tell her it's okay if you kiss and if it goes any further to let it happen. Maybe a good fuck will snap her out of it. You mean you'll let me fuck her. Sure, if you don't mind. I don't mind as long as you know.

The following Monday, I took her home and she turned and let me kiss her. Her lips parted and she accepted my tongue with a slight moan. She asked if I would come in. We sat in the kitchen and she opened a bottle of wine. I said, I shouldn't drink, I have to drive home. She said one glass wont hurt. As we talked, she drank two glasses of wine, while I sipped on mine. She got up and with the last of the wine in her hand went in to her bedroom. About ten minutes later, she called me.

I went in and she was sitting on the bed in her nightgown with the sheets pulled down. She looked at me and said. Every time you kissed me goodnight I wanted this to happen, so if your willing, will you come to bed with me. I never hesitated and undressed. She stared at my erect cock and gulped some wine. I drew her nightgown off and bent over and kissed her deeply tasting the wine on her tongue. I could feel her hand on my cock. She said it's been so long I wanted to touch it.

I lay her back on the bed. Her body was still in good shape. She resembled my wife nude. I kissed her as I put my hand between her legs covering her pussy. When I touched her vagina, it was very dry. I reached over and took some wine in my mouth and moistened her vagina as I lightly licked it. I rose up and carefully entered her as she gasped. I started moving a little and she wrapped her arms around my neck and pushing up, urged me on. I started fucking her in earnest as she moved to meet my thrusts. It seemed like forever, but she finally said, YES! YES! I'm cumming. As she settled back, I shot the biggest load of semen in her pussy then I have for a long time. It was the first time I fucked another woman, since I was 22.

I got home about before 11pm and showered and went to bed. My wife usually came home close to midnight. She always liked me to eat her after bridge, and I knew those "Ladies" liked to talk about their sexual experiences growing up as teens. There is eight of them. There all married and have children and most are Grandmothers. They mentioned, having sex with Brothers, or a Cousin, two mentioned it was a Sister and one said it was her father. She always came home, horny listening to all the stories. I asked her if she told them about her teen years. She never ever answered me. She asked how things went with her Sister. I said, very well after she had some wine for courage. I suppose you enjoyed it? I guess your too tired to eat me now? I'm never too tired, you know I love to make you cum.

Her Sister came early on Thursday, before I left. She had her hair done and what looked like a new dress. She had flowers for my wife, who asked what they were for. She said, I think you know and I'm taking you out to lunch. After dinner, my wife was getting ready to go out, and said, Sis is a changed woman, she looks good and acts younger. We had a nice day, a nice lunch, went shopping and she couldn't stop talking. She kissed me and said keep up the good work. I said, the pleasures all mine. She laughed and replied, Don't forget who your wife is.

When I took her Sis home, there was no wine, she was eager to get in bed. Over the next few weeks she became an eager sex partner. She sucked my cock, I ate, (which her husband never liked doing). My wife asked me not to shower when I got home. The next time, after in bed she kissed me and said I want to see what my Sis tastes like and she took my cock in her hand started. She went eagerly at it sucking. When her mouth went up her hand went up, when she sucked down her hand went down. For the second time that night, I shot my cum, as she swallowed every drop. She said it wasn't much but you did save some for me. I think my Sister tastes a lot like me. What do you think? I said maybe. Well get down there and get a taste of me.

She never wanted me to shower when I got home. She wanted to smell her Sister on me, and wondered if I could fuck two women on the same night. I could get hard but it was a struggle to orgasm, but I could make her cum. One night, her Sis and I never fucked, I ate her and we lay and talked. She told me about her early sexual life, saying the first was with a girl for a while, but then she became very into boys and had a very active sex life until she met
her husband. I asked, who the girl was. She said, I can't tell you, We're still good friends. That night I fucked my wife and shot a big load in her. She was amazed that I could do it. I laughed and said, I never fucked tonight. I saved it for you. But I did eat her and she told me about her early sexual experience. My wife asked if she mentioned any names. I said no. We kissed, she sucked my tongue and said, I can really taste her juices now.

(I began to wonder what was on her mind, wanting to taste her Sister on me) (I began to wonder who the girl was that my Sister-in-law had sex with)

It's been going on almost four months now. My wife and her Sister are getting along great and enjoy going out for lunch and shopping. Her daughter can't believe the change in her Mother and thinks she has a boyfriend. As for me, I'm getting more pussy then I ever did. When the golf season ends, the three of us plan to go to Florida for about three months. I can golf and they can spend the days together doing whatever they like.
