Grandma's Dog

I'm Lauren 35 single, I inherited my Grandma's dog Randy (4yr old). Grandma Marge had passed away in May she was 77 and she left me her dog and house on the condition I took good care of Randy. Marge had been widowed at 59 and a couple years later she got a dog Buddy and not too long before he passed away she got Randy. She really loved her dogs and I was the only one who went and seen her regularly and her dog was always beside her. I like dogs and Marge saw that and I think that's why I got the dog Randy, Randy doesn't take to men very well I noticed a couple times I visited Marge. I thought being with Marge, he became use to a woman and so men weren't trusted by him. I moved in to Marge's home just before her funeral to take care of Randy. For the first few weeks Randy was really sad I thought and just laid in his normal spot hardly moving at all. I was working from home as I preferred it and as long as my work was done, the boss didn't mind at all. After a hew weeks working from home I had started getting lazy, I didn't dress after getting up and went about in PJ's. Not that they covered much, I only dressed if I was going out somewhere. Randy started to recover from the loss of Marge and hung around me more often. Getting very affectionate towards me, I took him for walks and swims in the river. On the way home after just a walk it started to rain and I got soaked. Randy shook himself dry on the porch and I entered the house and stripped of my wet clothes and put them into the laundry. I was going to have a hot shower, but my cellphone rang. It was my boss he wanted to thank me for getting a projected written up quickly for him on very short notice. I was pretty happy with myself after the call was finished, sitting there totally naked. Randy came over and I gave him a pat, he then put his head between my legs and started licking my pussy. At first I told him to stop and go and lay down. He took no notice at all and continued licking my pussy. He also got his tongue to enter my pussy and it gave me a great frill and I almost orgasmed straight away. I had started enjoying getting my pussy licked, so I let him continue. But he wanted to mount me also and was really trying to do it. I pushed him away and said stop and lay down and he did. Then I remember something Marge had said to me on one of my visits before she passed away. She her dog as better company than a man and gave her great satisfaction as well. I hadn't thought much about it till than, maybe the old girl getting herself off with help of her dogs over the years. I sat at my computer and checked the internet for dogs fucking women. I saw some very revealing photo and videos and all so saw a large dog laying its back and the woman squatting over it and it was really fucking her. I thought a dog wouldn't do that, I looked at randy and he was laying on his back like the dog in the video. I thought no way and decided to prove it to myself, so still naked I squatted over Randy laying on his back. Nothing happened at first I was a too far forward, so I moved back a little and Randy was trying to get his now rather large cock into me. He missed several times and just as I was about to get up he found my pussy and was inside me. He started going like a rocket and I was soon enjoying it quite a bit myself. He blew his load inside and I had also orgasmed myself, later I decided to try on all fours as well and Randy soon mounted me. I realized I was really enjoying the servicing from Randy,. Satisfaction was great like Marge had said, I'm no model I'm overweight don't get asked out much and my rubber dildo was my sexual partner till then. It had been replaced by Randy and he could do more than the dildo could, I threw my dildo into the trash and Randy became its replacement and still is today almost a year later. I've had lesbian relationships before, but Randy is a much better licker than they were
