For some reason I was very curious sexually very very early in life. As far back as I can remember I would hide under the bed and play with myself, let bugs crawl on my dick, take peeps at people changing in front of me, etc. i remember being outside playing and a stray wondered up in the yard and laid on its back wanting belly rubs, I noticed a phone number tattooed on it's sheath. I have no idea why but I made sure I was alone and reached out and touched it and stroked it. My next experience would be a couple years later, my uncle had a lab that he used for hunting that stayed in his backyard in a pen. One day i was wondering around and knowing no one could see me, I pulled my pants down and spread my ass and pressed it against the pen. I had no idea what my intentions were but to my surprise the dog came up and started to stick his tongue and deep as he could into my ass and I loved it. After that every day when I would get home I would make sure I couldn't be seen as I naturally knew it was taboo and had to be kept a secret, and I would press my ass against the pen and stick my cock and balls through and let him lick as long as he wanted since I couldn't orgasm yet. Fast forward a few years and we had moved. I had started going to my mom's on the weekends and her boyfriend had a lab puppy but as it got older he would push his nose into my crotch so I would take him out of site and let him lick. It wasn't long until he was a fully mature dog and I had just made myself cum for the first time and our sessions were becoming more frequent. I had also found a porn magazine stash in my stepdads bathroom so when I was left there alone I would take the dog into the bathroom and get undressed with my legs in the air and he would go to town on my cock and my ass while I looked at the porn. I thought I had to be the only person that had done anything like that until one day I found a beastiality Literotica book at the bottom of the secret magazine stash. Then I started to realize why the dog was such a natural at it, I wasn't the only one he was involved with and the book made me realize it was so much more common that I could have ever imagined. I also found beastiality porn in my stepdad bedroom I would pop in his VHS player and lay spread out on his bed while the dog made me cum. As the dog matured even more, licking me would make his cock hard and he would hump the air so I started letting him fuck my hand until he shot his load to return the favor. I had also found a stash of anal sex toys in my stepdads room and I then understood why licking me made the dog want to fuck. I attempted to let him mount me on several occasions but it always hurt too bad after a few thrust so I would just finish him off with my hand. One time my mom walked in the room right as his cock slid in my ass and I thought I was fast enough getting my pants up and pretending I had no idea what he was doing and asking why does he keep jumping on me I think she knew but never said anything. There would also be times they would come home and the dogs knot would still be swollen and when they would ask I would just say idk, he was in the other room until y'all pulled up. One day he got out and got hit by a car and didn't make it. I've had many other experiences with dogs since then but I've never been mounted. I still have no idea why this is something that started so early in my life but it's something I want to explore as much as I can. I'm a straight male btw, only attracted to female humans
