Family Secret

I'm Gavin 24 only child of Helen and Robert both deceased for 3 years after car accident. I was at university when I got the news and continued on with my studies after the funerals. I'm in my final year and doing well. I live with my grandmother Anne 62 widow and her other daughter Emily 40 single. No relatives on my father's side that I'm aware of. Since the loss of my parents I lived with both Anne and Emily. Last Christmas I found my late mother's diaries while going thru things stored in Anne's garage as my parents home was leased out and the furniture sold and personal things stored at Anne's garage. I was going thru sorting out what to keep and what to trash. Lot of Robert's papers weren't needed or of family interest and were trashed. While going thru my mother stuff I found one of her diaries and started to read it. Nothing really interesting and as I check thru I found another then another, most weren't very interesting. But one really got me interested as she wrote that her late cousin David (died in 2006 on active service) had taken her and Emily's virginity and was also fucking Anne as well. David was regular visitor to their home and had seduce them all over time. He was in the army and came every chance he got, he was also still fucking Helen after she had married my father Robert. But wasn't my father as he was overseas went I was conceived, but was back to fucking Helen as soon as he was back. From Diary accounts Helen really liked sex and Roberts not as much, so David made up for the lack of interest by Robert. After reading the diary, I guessed that the women of my family had high sex drives and I wondered who was doing them now. After some investigations I found no sign of any lover of either or both. I decided to see if I could interest either in me as a sexual partner. Anne goes to a church social group every weekend and is gone most of the Saturday afternoon. Emily is home alone except for me and she usually does washing and other things. So I decided to let catch me masturbating, at most I would be told I shouldn't be doing that. Then if I made a pass straight for her, so I watched her and when she was folding the clothes I went and laid naked on my bed and started to stroke my cock. I started to think she wasn't going come in at all, but when I was about to give and see what she was doing she entered and saw me still cock in hand. She said sorry to interrupt and was about to leave. I told her she wasn't interrupting as I was useless at it anyway. This stopped her leaving and she asked why I thought I was useless at masturbating myself. I answered saying I can't get it cum I lose interest or something and it goes flat like it is now. My cock having gone limp, do you have any magazines or other things to get you more motivated. No I don't I replied, then thinking she was about leave, I got and started putting on my pants. She told me to keep them off and she would try and help me get off. She said she would stroke my cock and see how it responded. So she started and I got semi hard again, but fast enough for Emily so she stopped and removed her top and bra and leaned her breasts against my cock. It got hard straight away, she resumed stroking my cock and I trying to think of everything to stop from coming. She then said I needed more help then she first thought and undress completely and sat on the bed beside me. Resuming the stroking and then sucking my cock, I was still try my hardest to stop from coming. I decided to start feeling her up and I put my hand onto her vagina and at the same time I came. Thinking was now over I stopped touching her. She suggested I shower and I asked would she like to join me, okay why not she replied. While showering with her I got another hard-on and deciding it was now or never asked her to let fuck her. She was quiet and then said okay, but no here back on your bed. Quickly drying each other we went to my bed and I fuck Emily and I thanked for letting fuck her. It was now getting late and we showered again and Emily went back to doing her housework and putting on the dinner. I wasn't sure if I would be able to fuck her again, I would just ask the next Saturday and find out. Later Anne came home and about hour later we all sat down for dinner. I was looking at Emily a lot and then she shocked me by telling Anne I had been having a lot of trouble masturbating and she had to help and we had ended up fucking. I waited for Anne to explode or something I didn't expect her to offer to give sex lessons as she did. After dinner was finished and everything put away. Anne told me that she and Emily will teach me everything I needed to both satisfy myself and any woman I was with. Sine that Saturday night I've slept either or both and I confirmed that women in my family really love sex.
