How I became a Bitch

I was 49 when I became my dog's bitch widowed a year earlier and my children all out on their own. I had my dog Duncan a gentle giant of a dog for company, I was well on the way to coming to terms with the death of my husband due to cancer. I wasn't looking for another relationship and avoided dating and being setup on dates by friends. The day it started I had been during a spring clean of the house and had cleaned up my husband's workshop and had gotten filthy and with grease and dirt all over me I stripped off my clothes to soak before washing and went to shower. Using a ball shaped sponge to wash myself. Then I dropped it and it fell on to the floor and bounced off the basin cabinet and rolled under the claw foot tub I was showering in. I got out and got down to retrieve the sponge, living alone I was in the habit of leaving the bathroom door open. Duncan usually laid in the lounge room, but this day he was just outside the bathroom and seeing me down on looking under the bathtub. He came in and tried to mount me, I told him to stop and go away. But he kept up trying and finally got inside me, he started fucking as hard as he could. I was in shock that he had gotten inside and told him to get off of me. He ignored me and just kept fucking me, as I couldn't get him off me due to his size. I decided to let him finish and then strangely I started to enjoy him fucking me and he had great stamina. I came before he did and once, he got off me left the bathroom. I showered again and dressed and went to see where he was and found him licking his cock and balls. I was going to put him overside but changed my mind. I would let it go as they say, Duncan didn't make another try. I thought it over and over and came to realize I had really enjoyed the fucking and it had been a long time since I had been fucked. Duncan was always close by as was usual for him and it was me who got horny again first. Finally giving in to carnal urges, I again undressed and got down naked and was hoping for a repeat from Duncan. Duncan at first showed little interest, but then he came over and started licking my pussy. I was getting pleasure from him licking me and was well on my way to an orgasm. Then he mounted me and was soon fucking hard like before. I orgasmed twice I think and could stand till I had fully recovered from the fucking. Since then, Duncan has become my lover and regularly fucks me. His very willing bitch.
