Elderly neighbour

I thought it would be nice to ask our elderly neighbour Bill if he needed anything at the supermarket as we are in lockdown. He gave me a list of groceries and off i went. When I got back i unpacked it for him and put it away. I asked him if there was anything else he wanted,he replied would you have a cup of tea with me. I couldn't see any harm in it so I took off my jacket and made the tea, I bent forward to put his tea down forgetting I had a low cut top on and he had a great view of my cleavage.I noticed that he kept looking at my big tits while I drank my tea.I asked him if there was anything else he wanted me to do for him, he said will you show me your tits , I thought why not give him a treat, so I took my top off and removed my bra, he gasped and smiled as I turned to face him he asked me to go closer to him so i walked over and sat next to him. He then put his hands on my tits and started caressing me, well I love my tits caressed and started sighing. He then asked if I would get his cock out and play with it.I undid his trousers and took his erect cock out and began stroking it, he then put his hand up my skirt and started playing with my pussy through my knickers, I said hang on a second and stood up and stripped off completely. I told him to strip off then i bent over the sofa and told him to fuck me. He slid his cock into my pussy and started fucking me slowly after about 5 minutes he said he was close to cumming i said cum inside me, a few seconds later I felt him explode inside me and making me cum.We then got dressed apart from my knickers which he wouldn't give back, he kissed me on the cheek and said thank you for the shopping same time next week and laughed. I then went home where hubby was waiting for me.
