A lonely Saturday. Just me and Rex

Another weekend with mom and off doing work or whatever instead of being home with their Daughter.

One Saturday I woke up and mom and dad were away again. I had stopped caring why as it had happened so often. I went into the bathroom for morning reasons and then I went into the living room. My boy was asleep so I turned on the radio and ate cereal. Afterwards I dance around to the music. I was only in my undies and Rex came in and bounced around with me. I had been dancing for a while and rex noticed cause he started trying to sniff me. I got a juice from the fridge and gulped it down. Rex titled his head and just looked at me. I couldn't resist turning around and shaking my ass for him, teasing him a little. Rex waisted little time in getting his nose in to sniff me but I wasn't expecting the lick of my puss. The sudden jolt flashing through me made me wet and I moaned. My reaction must have encouraged him cause he started licking me very big, repeatedly. I quickly dropped and yanked my undies off and spread my legs. Rex quickly dove in and began licking me in big slow licks. The deep licks were very hot and had me soon cuming. He licked me throught 2 orgasms before he proceeded to mount me. He was very hyper and it took a few jabs to get inside me but once he was in, he started slamming me while he was getting bigger and thicker. I couldn't stop moaning and begging him to fuck me. I could feel his cock starting to swell. Bringing me to more orgasms.

At this point I couldn't stop cumming. Waves of pleasure flowing from my pussy all throughout my body. His knot felt so amazing finally getting stuck inside me and still growing. Feeling it pulse and grow, filling my pussy. Suddenly I felt the flood, making me cum harder. This hot river flowing into me. I felt like a river was in my insides. Her I was, nude on my living room floor with this wonderful dog on top of me with that big damn cock stretching me and making my egg in my womb have to swim in k9 cum. I laid like that for next long while before Rex's knot popped out of me and his cum ran out of me. I love my boy!
