Drunk ass has no owner...

My name is Thiago, I'm 15 years old, I'm blonde, brown eyes, 170 cm, 71 kg, neither fat nor thin but fit, because I've been doing martial arts since childhood, at 16 cm and I'm in second grade. I have a white Labrador and beautiful caramel and I'll tell you what happened to me a few days ago. In the middle of the holidays, my parents had gone on a trip, and I ended up staying at home because I didn't care where they were going. I actually wanted to be alone for a while, and every once in a while my older brother would come by to check on me. I was home alone, and I got excited, and I turned over some bottles of wine that I had in the cellar, and I ended up getting really dizzy, and I don't really remember all the details, but I do know that a few hours later, I woke up naked, on my stomach in my bed, feeling something cold on my ass. I was still a little groggy from the booze, so it took me a while to figure out what it was. My Labrador, Flash, was sniffing me, with his snout stuck in the middle of my ass, licking me like crazy. Until then, I'd had a few fights with a couple of mules my own age, and one of them a more steady relationship, but I'd never been turned on by a dog. I got mad at Flash and tried to get him out of there, but since I wasn't in my best shape, I could barely talk and move. I don't know what I did, but I finally managed to get the Flash off me, but as I moved I fell out of bed. By the time I started to get up, leaning on the bed, I felt my dog licking me and by the time I turned to fight him, it was too late. He was already on top of me. The Flash crossed his paws on my belly and became firm when his paws were firmly on my thighs. I tried to get him out of there, but all in vain. When I saw, he was already punching my butt. At that moment I got excited and my dick went up. I relaxed and put myself in a better position to be able to guide that hideous puppy to my little entrance. In one fell swoop, the Flash thrust his then-thin, but very long, dick all the way to the bottom, and it was like I could feel the Flash's dick poking my stomach. His rhythm was so fast it seemed like he was going deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper and deeper. Suddenly, I felt a pulsar on Flash's stick and as that pulse came he gave a single, deep punch. I felt a hot deal warming up my ass even more. Again, another pulse, a punch and more fun in my ass. I felt very full. It seemed like I needed to go to the bathroom. But it was very good. In that moment of great temper, I had a lot of fun and still my punch mixed with Flash's punch that flowed from my ass went through my bag and dripped on the floor, which was completely wet with my sweat. Thinking that it was all over, I was going to try to get up when I got a surprise. I was stuck to Flash by his dick. Up to that point, I had no idea what the knot was that dogs have on their dicks, and I learned a biology lesson the hard way. After all this transaction and because I had sweated a lot, I was already more awake. I looked at the clock and Flash and I were stuck for almost 15 minutes. During that time I still enjoyed the second punch, and the amazing thing is that it looked like I hadn't enjoyed that day. I enjoyed a lot of fucking. Then he forced himself a little bit to let go. Until I heard a pop when his dick came out of me. Along with his dick, a fuck came out of me. He laughed and came out of my side and I fell on my dick, because of my sweat and because of Flash's dick. When I looked around, I could see the size of Flash's dick. I was very frightened by the size of the roll that was on me. His dick is much bigger and thicker than mine. And the ball is almost a closed fist. I was still recovering and Flash came and licked my ass. I was laughing a little and then I got up, I went to the mirror to see the damage he did to me. When I looked, I saw that I was enlarged and could easily put four fingers. Because I was soaked in my own fucking and Flash's and sweating so much, I went to take a shower, and when the water touched my ass, it burned so much, I walked around for a couple of days with a pain in my ass, but luckily, a couple of weeks later, my ass was brand new, and I loved the experience.
