Somehow he knows when we are home alone and he takes advantage of it. My dog is so sneaky

I have a 6yr old chocolate lab named blaze, I had hem ever since he was a puppy and as you can imagine we had A LOT of sex in those years, And we still do. We hadn’t done anything in about 4 months. Well that was until yesterday lol. I Had got out the hot tub and when I got out and took off my wet clothes, before I could put my dry ones on he shoves his head in between my legs, my cock all in his face, I couldn’t stand it any longer, we both were rock hard, I opened the door and he runs straight to my room, I throw a blanket on the floor I laid down and he laid on top of me with his hard red cock dripping cum onto mine, we kiss each other as if we were making out... The whole time I’m stroking his huge cock ever do gently. I couldn’t stand it any longer so I get on all fours, he never skipped a beat he was already on my back paws wrapped tight around my waist. I reached back and slipped it into my ass, and it was on he almost immediately knotted me. We stayed together for at least 20 min. The whole time his huge cock was sunk deep inside me I could feel it inside my stomach! He was deep while his knot was stretching my asshole his warm cum filling up my insides.. Im about to go warm that knot up agin for hem. I hope you enjoy you day.. me and blaze are about to really enjoy ours
