My son marriage and business collapsed

My son Mike marriage broke down and they divorced and his business also went bust due the pandemic. He didn't have any reserves due the divorce and couldn't last thru the lockdown. So with nothing left with nothing and he returned home to live with me, I'm Marion 47 widow and husband passed away after a bad car accident 4 years ago. Mike is my only child and I was delighted to have him back home. Mike didn't have any children and so I he was really down after the everything that had happened. I live in a cottage with 2 bedrooms and 1 bathroom. Shortly after he returned home I walked in on him in the bathroom. Both were shocked and I quickly left the room, but as sat waiting for him to finish I couldn't get the sight of his cock out of my mind. It was huge and it wasn't hard, just it was just hanging down between his legs. The next day he return home after looking for work with no luck. Mike said he was thinking of moving to find a job. I didn't want him to go and told him to stay as he would find a job shortly. But I knew he was still thinking of moving away. When he went to have a bath, I undressed and then joined him in the shower. He was shocked by my actions, but as I went down on him sucking his cock and he started to respond and after I had sucked his cock hard he fucked me. Since then he has slept with me ever since. He found a job the following week, he puts his success down to fucking me and improving his attitude to everything. I on the other hand am happy with him at home with and also the fucking he gives me. I still want him to find a woman give me grandchildren, but until then I'm his sex toy.
