My neighbors dog,Rex

Since I turned 40 my sex drive has increased to such a level that I am always horny about a week before my period. I am usually at home alone in the days, I'm a stay at home Mom.
I was teasing my breast and pussy thinking of past dicks that I have, yes I have been fuck but not able to cum.i only cum fucking myself.

While fingering my wet pussy, I heard a whiny sound at the door, from the front to the back, it was my neighbors dog Rex, who was all excited, jumping and spinning around me.

I let him in and realized he was horny, I got naked, and lay down on the settee, he begin to lick my pussy, shit it was good, I was creamy from my pussy, as he lick I fondle my breast, he lick hard black nipples.
I was in high mood, I touch his cock he begins to hump so I guided him into my pussy, oh it was hard, fast and intense, he was enjoying it, fucking me, licking my face, I was his bitch, he was going deeper and his nuts was inside me, I was in heaven...the dog was making me cummmmm...after his final thrust, I was still screaming, wining on his doggy shaft as it tickles my clit and Yesssssssss it was so good as I hold him in my pussy and his warm squirt floods my pussy, as he whine with pleasure. No man has fuck me and make me feel like that.
So Rex and I have an understanding, he comes over and I am his willing bitch, trying all sort of position, I even suck his cock.
