It was hot but I really didn’t want my knees to be on concrete so I took Max out to the open pole barn where there was lot of hay, also I knew it was a great place to get fucked because it was oriented to where it was hard to see inside. Whenever my best friend TJ or my brother Gene fucked me, it was where we went for just that reason, plus it was cool but well-lit by the sun inside. I pulled off my pants and sat on a burlap bag covered hay bale, Max came over to me when I called and sat there happily panting as I petted him then reached down and grasped his cock-sheath. I was starting to pant myself as he stood to give me better access to his organ as it quickly started to poke out and then grow in my warm hand, his still unswollen knot popped out of its sheath, pushing it behind. I was on my knees in the hay quickly as I dropped down and put my mouth over the tip of his dick and started licking the puckered hole and the little pointed knob that stuck out like a hood over the opening, swirling the little drops of precum and my saliva over the first inch or so.
As I did Max shoved several inches of quickly swelling dog meat in and out of my mouth as he started to involuntarily drop his pelvis and hump forward, I had to grab his hind legs and push back to keep from having it forced down my throat. Humping fast now his knot started to grow, I grabbed his cock in front of it to control the action of my mouth working on his fattened shaft which grew to be about 5 inches past the knot, so soon I could take the entire thing in as I sucked and licked my tongue all around it. My mouth was filling with his thin musky jizz that was spurting in pulses, making me gulp and swallow my saliva and the warm watery liquid because it was drooling out of my mouth and soon my nose as well, my eyes watering as I gagged and choked it down until his cock, my face, and the hay beneath us was a soggy mess.
Maxs knot was huge, almost the size of a softball but hard as a rock, and as he stopped thrusting so much and pushed slowly forward and back I grasped it and the hilt behind to slide my slime covered hands all around it. I could feel it throbbing deep inside but the surface remained hard to the touch, it was light pink to almost white on the underside, and besides being covered with red capillaries it also had a huge vein on either side, snaking its way over and around the knot. The veins pulsed visibly as his dong throbbed between my bubbly lips, his squirts of juice now becoming larger and larger, making me choke with each blast from the tip but I was NOT going to take my mouth off it even if it was now coming out of my nose and my working lips in streams. Finally I couldn’t breathe and I fell back as his beast dong separated from my face in a gush of foam, Max standing there in one place breathing fast with his butt hunched forward, looking at me with a smile (he was a very happy dog!) and his long tongue lolling from the side of his mouth.
I got back onto my knees and kneeled beside him to hold his cock and knot in my hands, it was throbbing and showing no indication of lessening, my hands and his member were still wet so I stroked his shaft and held his steaming knot and masturbated him slowly. I had forgotten myself, so I took my right hand off his knot and wrapped it around my own stiff cock and greased my boner up with the mix of our juices, then I rose up and put our cocks together, tip to tip. Max giant squirts were very hot on my pubes and soon my cock and crotch was coated with the skunky smelling liquid, I was stroking it all over me then I pushed my cock underneath him and rubbed our slippery cocks together, mine under his then mine under his. It felt so hot as I pushed my hand around us, frotting our spasming organs, human skin against dog skin; being young my cock was flowing juice out and onto us both, mixing with his with a slopping sound which grew faster as I approached my orgasm. I shot load after load all over the two of us, soaking Maxs belly and sheath as well as his cock as my hand flew and splattered our cum over the both of us. I must have spurted 7-8 times, the first 4 loads so hard my asshole, taint, and balls hurt with electric pleasure squeezing them out, and semen hung from the tip of my cock in streamers. Again I fell, this time under Max deliberately and as he stood there, both of us trembling I licked and sucked his cock and knot clean of both of us, then I pulled him down to lie beside me.
Max licked both of us clean as his hardness diminished, and he was a very affectionate dog to me then and on afterwards, and I petted and praised him as we laid there on that hot summer afternoon, both of us having enjoyed each other. Max became my “Blowjob Dog”, he was surprisingly calm when he knew he was going to receive some head, but later on once he had taken me gettin fucked by him required supervision. I didn’t mind though, because I LOVED going down on him and he was eager from it ever time. I have had many experiences in sex, with men and women and I consider myself Bisexual, but my Canine experiences have been most memorable, and this was my first. But it wasn’t my last!
