Please excuse me for restarting this story, upon rereading i saw it was never finished.

This goes back now a few years when Karen and i retired and planned a trip to Florida to avoid New York winters. Karen and I had been in the swinging lifestyle on and off for at that time over 40 years, we had always kept it private from family and friends. I am 5ft 10 about 195 grey hair and an average 6 in cock. Karen is 5 ft. about 120 short reddish hair 34 a boobs and a killer butt.
We were sitting around the living room with Lucy Karens younger sister. We were telling her of our up coming trip and retirement plans. We showed her our motor home . she said she was jealous , saying she wished she could join us. I smiled to myself and to Karen because we had planned to visit nudist resorts and was hoping to have Karen laid in every state we stopped at, so having Lucy join us was for sure not in my plans. Karen explained she wasnt sure that she was up for that. Lucy asked why I looked at Karen I had not expected her to really answer or tell the truth. She started by telling her that we had planned to visit nudist resorts . I looked first at Karen with shocked look on my face and then at Lucy to see her surprised reaction. She asked if Karen was serious or just joking .Karen responded she was dead serious that we had been nudist for years and really enjoyed the life, she went on to say we met some very nice and sexy people. I am shocked that Karen has gone this far in describing our life, but I was curious , and excited to see how far she would go.

Lucy reaction was no way she did not believe her. Karen said it was true, she got up went to our bedroom changed her top, removed her bra and got our photo album. Karen then placed the book on the table and told Lucy she could look but had to promise not to tell anyone. To say i was both hard and shocked would be an huge understatement. Lucy Promised and opened the book, the pictures went back from when Karen was 21 and me 20 to the present. All Lucy could say was oh my God, Karen then joked still want to join us . Lucy never answered just kept looking through the album. Karen got up took off her blouse and her shorts teasing might has well be comfortable. Lucy looked at her big sister with a stare of disbelief. Karen asked her if she still wished she could come with us. Lucy did not answer she just looked at her sister in wonder, Karen looked at me and laughed since when do i stay dressed. i looked at them both asked Karen if she was sure, she nodded yes . i stood up removed my shirt and my pants and underwear in one motion naked now in front of my sister in law. Lucy lifted her sweater over her head giggled and said nudity is cool. I watched has she finished undressing she had bigger boobs than Karen and were covered in freckles The other surprise she was shaved bare ,she laughed and said could she come now. It was so wild the 3 of us being naked I did not know what to expect.

Karen said there was 1 other surprise , that she needed to know. She got up sat next to me and started to stroke my hard on. She told her that over 40 years age even before we were married we were introduced to swinging life by her then boss , and that we regularly and had sex with other people, both couples men woman and groups. That we enjoyed being watched and watching others. Since Karen was playing with my cock i started to play and stroke Karens very wet pussy. Karen told her that she was welcome to come with us , but she didnt have to join in with the sex if she self uncomfortable seeing her sister getting laid, Lucy asked if it was ok if she only watched at first and see how it went, we both said yes.

she did not join in at that time, but she watched and in later weeks joined us at a swingers dance club we used to visit
