This happened quite some time ago , Unfortunately my wife was very ill , and with 3 young kids , my wifes sister used to come down of a weekend to help out with all our problems, She was a great help . One particular night I hugged her and gave her a good long kiss just to show her I really appreciated her fantastic help , At that time I didn't mean anything than just showing my genuine appreciation , As I embraced and kissed her , there was a good response , As my wife was very ill I had enough on my plate . A month or so later unfortunately my lovely wife passed away . my sister in law kept coming over to assist me off a weekend with my 3 young children , I gave her a few more hugs kisses etc , and there was a great response . well one thing turned into another , I suggested that I get her to come into my bed at night as we could have a little privacy , Well I have never ever had such an erotic time . She gave me my 1st head job and l let go right down her throat in the first 5 mins in the cot I then gave it to her in every way possible , She was making a hell of noise and I was trying to keep her quite so my children wouldn't hear . next day she told me my cum tasted like cavier . Over the next 2/3 months whenever she came over , I would cum over her , It was great while it lasted , I did feel a little guilty , her hubby never found out , and we only discuss it when its approiate , If only I could find some one I could have erotic sex like that again Its great to have some great memories
