Note: This story was dynamically reformatted for online reading convenience. As a kid, I grew up wagging school. Divorced parents from my age of 11 years old, I was a horny little bastard and I'd often wait in the park across the road from home for my mother to go to work before I could sneak back home and waste another day doing the usual - wanking, and nothing special - certainly not school. During my times in the park waiting, sitting under a tree on the sidelines of the park with a total view of everyone and everything coming, often it would be neighborhood dogs that would sus me out as they explored the neighborhood and they became kind of like my friends too. Over the next few years, these dogs and I became more than just friends. It started with me being horny of course, and me playing my with my cock when one of the dogs was saying hello, and while it was open ground, I could see anyone coming from like 500 meters away and I always felt safe to wank my cock quite openly. So, down the leg of my school pants, I had my cock out of the leg of my shorts and undies and was just rubbing it - not even wanking hard core, but it was rock hard and felt great. The thing that changed my life was when the dog started sniffing my cock, and when he seemed more than just curious, I pointed it at his snout and he just got on it and licked it like we'd been doing this forever. I fell in love with that feeling totally and it seems he wanted it too. He'd lick my cock for a minute or two, which doesn't sound like much - but hey, you get your cock licked and look at the second hand on a clock and 1-2 minutes is a wonderfully long time. Whenever he stopped licking me, I'd be begging and pleading for him to continue with his licking, and sure enough he would restart again while I spanked my monkey. Sweaty and horny, crawling on my ass from cheek to cheek to get more of his tongue and mouth on my cock, me wanking away now having forgotten all about who may be approaching from the distance, I was totally out of control and eventually my cock exploded on the dogs tongue, nose, snout and my mind just spun out. To the dog's credit, he wanted all my sperm and gobbled down all my spunk, and it tried real hard to get the splash from between his eyes with its tongue. I helped it get that last bit of sperm by pushing it closer to its mouth. This day was the start of me and dogs, and no less than 200 times I have taken the risk to find ways to spunk in their mouths. So, from the age of 11 to 13, I did have almost every male dog that came into the area and they all did come and suck/lick me off, and I also played with their cocks every chance I could get. But like all things in life, things change and certainly my life changed when I got kicked out of home for wagging too much school. In fact I really got kicked out because my mother found a condom floating in the toilet from first sex with my girlfriend - but for sure that was just her excuse for me being an asshole. Later in life, at 16 I met and started to fuck the first girl I ever kissed and a few years later we married. At 17 was the next dog experience I had which was a gap of 4 long years with only memories to wank with. Sex with the girlfriend was great and we'd fuck like rabbits every chance we got, but it was after coming home at 17 that I had my next level doggie experience - literally. I was living on a rural fringe property of maybe 2 acres of bush, with my side of the duplex half being one bedroom, and the landlord's being 3 bedrooms on the other side. I came home from work and as I got out of my car, a medium sized dog came out of the bushes and it immediately approached me, tail wagging and happy to see me. I squatted down and from my experiences as a pre-teen sex-addict, when this dog stuck its nose in my crutch I knew immediately what it wanted - it wanted to lick my cock. I didn't hesitate and freed my cock to give it total access to do what it wanted to do to me, and while it went to town on me with its hungry and greedy licking, I only then started to look around to see if anyone could see us - which they could not as the closest house was an easy 100 meters away. I let the dog have my cock to lick and he was greedy with his tongue and I had missed this kind of action over the past 4 years. Hard as a rock, and wanting to make up for lost time, I was plotting and planning what else we could do. Certainly I wanted to get my ass licked, and certainly I was thinking about how I could let this dog get his rocks off too. So after about 5 minutes of glorious cock licking, I took the decision to break contact and head into the dense bush area only 10 meters in front of me. Of course the dog followed, him jumping up at my crutch the whole time and making pining noises to start the action again. In the bushes, only about 5 meters into them I dropped my shorts and went to my knees and I was immediately rewarded with his greedy tongue trying to tunnel for gold up my ass. God I do love this feeling and how aggressive and free dogs are to go for nasty sex. I wasn't all that surprised when the dog mounted me. In fact I was kind of hoping to satisfy a dog with my ass for many years - just that I'd never tried it before, and so when he jumped on my back I really did think cool, get your cock up me and enjoy yourself dog. I truly wanted the dog to have a good time - I wasn't thinking about what it would feel like for me other than I wanted to please the dog with my ass. Was I in for a shock or what? This dog hit the mark in no time flat and it fucked the shit IN to me. It pounded me so damned hard that even though I was consenting, it was almost a violent rape of my virgin ass. It truly went to town and hurt like fucking hell. Even so, even through all the pain, I did grit my teeth and I opened myself more for the dog and I steeled my courage to persist and let the dog finish what it wanted from me. Even though it hurt terribly, I was wanting the dog to enjoy himself fully and I let him continue as hard as he wanted. In my horny state of mind, I'd totally forgotten about the dog's knot and what it could be doing to my tiny asshole. After maybe 30 seconds of hammering me, I could hear sloshing sounds which I knew was either the dog coming in my ass or it was my blood adding fluids to the mix. I learned later it certainly was blood - he'd ripped me a new asshole, as they say. Even with the intense pain and me suspecting he'd torn my rectum up, I still let him continue, all the while gritting my teeth and letting him do what he wanted to me. There was no other pleasure in it for me than wanting to let this dog have a good time. I really did want the dog to enjoy his fuck. Did I hope he would stop? Sure! Did he stop? No fucking way and I was almost in tears from the pain of it all. It really did hurt a LOT! But mostly I wanted him to enjoy himself. I wanted him to orgasm up my ass and be satisfied with finding my hot asshole for his cock. I wanted this dog happy - even though it did hurt me. Soon enough though, there was a sound of a car coming up the driveway and I knew it was my landlord. I knew I had to get this dog's cock out of my ass and to get out of this situation. If the landlord caught me, there would be hell to pay and he'd not hestitate to blackmail me into every nasty act he could think of - my landlord was a dirty old man of the worst order.
