Grandma caught me

Early last year I was at home and my mother's friend Elizbeth dropped by to see my mother. But she and my father had gone over to the next to see my older sister Harriet 24 who had just returned home from holiday with her Husband and 2 children. They had not long left when Elizabeth arrived, Elizabeth 58 is a widow and fairly good looking and she started to talk to me. I'm Raymond 19 youngest of 2. Elizabeth asked all the usual questions and became quite interested in me when I said didn't have a girlfriend. Anyway one thing led to another and Elizabeth started sucking my cock and then we fucked. We finished and Elizabeth left, she had just left and I turned around to find my grandma Heather standing looking at me. Heather 61 is also a widow and lives in a house straight behind ours and has a connecting gate. I was sure I was in trouble, but at first she wanted to know how long I had been fucking Elizabeth. I told her that was our first time and I don't expect she will be wanting more from me now. Why that she asked, well you know and soon mom and dad will know I replied. Well if you give me a good fucking I will keep your secret she answered. I was shocked quiet at first and finally said okay. Then Heather said lock up the house and we'll go over to mine. I did as instructed and on arrival at her place she suggested we shower together first and then fuck. She didn't have to do much to get my cock hard and I fucked in the shower. After we went to her bed and continued fucking. After fucking her 3 times I went home. Heather told me she would like me to fuck her again and hoped I would. I said I would happy to fuck her again. Next day I rode over to Elizabeth and she invited me in for cold drink. Several hours later I left after fucking her twice. I got home and dad was leaving to play golf and mom was also going out to see Elizabeth and other friends for coffee. They did this almost every weekend. I locked up the house after having a shower and went to see Heather, who was happy to see me. I gave her cuddle and a quick feel up, she smiled asked was I back for sex. I nodded and she led me to her bed and we fucked again and then we showered together. I've started to visit Elizabeth and Heather every chance I get and get sex most times.
