My best friend

My husband died of Covid. and I was left alone with our dog. My children are all grown and see regularly me a monthly basis. But I still felt lonely at night and when my dog started licking my pussy, I was at first shocked and told him to getaway. But it had simulated my hormones I suppose and the next time he tried it, I let him keep going. The third time I removed my panties and the fourth time I let him mount me. Now I'm his bitch and he is smart enough to only try for sex when we're alone. He lays nearby me when I have visitors and only after they leave doesn't show interest in have sex with me. I feel well and truly satisfied sexually and don't go dating at all.
