My Grandmother is a Gambler

My grandmother Michele 65 is a gambler and usually does okay, but early last year she had a losing streak and lost their holiday money. I'm Martin 27 single and have a great well paying job, I'm not in a relationship and find it, hard meeting women. I own my house, mainly due to my boss who helped me get it cheap. It was really run down in a great neighbourhood and not far from his place and he found the owner and got them to sell it cheap to me. He also got his brother in law a builder to oversee the house's repairs as well as doing some himself. It, not a palace but it has 3 bedrooms, 2 baths, double garage and a large shed outback. As I'm on a corner and the shed is all-steel construction and no real use to me, the brother in law uses it for storage and as it has its own entry from the side street he can come and go as he wants. I got a great house at a lower cost and its value is more than double my whole investment. Anyway back to Michele, she lost $ 8500-holiday money of hers and grandad Richards. They had paid for their trip and the 8500 was their spending and other expenses cash. She was in a fix as she put it. I was the only person who would be able to lend her the money, but how was she going to pay me back without everyone else knowing about her losing the money gambling. I gave her the money no problem and wasn't really worried about getting it back. But she was insistent I she would pay me somehow, as I said before I'm not a ladies man and was still a virgin. Michele is a slender gooding woman and she offered to give sex lessons to help my confidence with women and I wasn't sure about it. But my cock went hard with me thinking about it and Michele seeing that started to caress my hard cock thru my pants and then she undid them and took it in her hands. Like the saying, I was putty in her hands and we had sex for the first time. She gave me regular lessons up to they went on their holiday and I thought that was that. On their return, she came over to my place and started the lesson again. I didn't ask how long they would continue as I was enjoying the sex, about a month later Richard had a stroke and passed away, Michele was devastated and couldn't cope at first. Slowly she came back to her normal self. It was then that she said she was going to sell her home as she couldn't live there without Richard. I thought she would move away somewhere and the sex would stop, but then she asked would I mind her moving in with me. I said I wouldn't mind at all, but not really expecting the sex to continue. My parent thought she should move in with them, but Michele said No Martin is alone and I think it would be better for the time being I live with him. That settled the matter and she moved into the master suite, I preferred the bedroom at the back of the house. But she had me join her the first night in her bed and we have fucked in every room of the house since then. I told her I considered the debt paid, but she said that nice, but I still want you to fuck me. That was a win-win for me as I thought I was forcing her with the debt hanging over her head. She told me that she really enjoys our sex together and after selling her house she could have paid me back if she wanted to end the sex sessions. I must admit I'm feeling more confident around women now and last June Michele went to visit Richards sister for 2 weeks and I felt lonely without her home with me. My mother Elizabeth 44 came by on the weekend my father Ralph was away fishing with friends and Elizabeth dropped by to see me. Elizabeth is a little overweight but still, a great looking woman, while talking with I started to get sexual thoughts about her. Then she asked me if I was doing anything special on the weekend. I said no maybe go to a movie and a burger, she asked would I mind her tagging along as she was bored at home alone. I answered no worries your welcome to join me, we checked what was on and she left after arranging for me to pick her at her place. A couple of hours later I arrived and let myself in calling out to Elizabeth letting her know I was there. She answered that she was in the shower and wouldn't belong, cheekily I replied do you want me to wash your back. Not expecting an answer, she replied only if I can wash yours. Before I started having sex with Michele, I wouldn't be game to say anything like that. But now I was more confident and so I went up the bathroom and knocked on the door, not entering just in case she wasn't serious. She called in and she was naked and told me to undress and join her in the bath. So I did and she went straight for my cock and we never got to the movie only her bed. She told me she knew I was fucking her mother Michele as Michele had told her of our sexual relationship. But not of the loan I had given her, Elizabeth also told me that Ralph wasn't doing much now and she liked sex a lot. I asked you don't mind I fucking Michele then, no I can see she is happy and that what counts. I hope you'll make as happy she added. When Michele returned she already knew I fucking Elizabeth and we even had a threesome together that first night she was back. Ralph was away again on business this time. I have started looking for a girlfriend, but no hurry as I get all the sex I want from Michele and Elizabeth anytime I want.
