I was 20 and I met this guy on beastforum and he was extremely kinky and had a dog. And we talked for like a solid year on there before meeting up and I told him about my anal kink and how I wanted my ass knotted by a dog.
His dog fucked him regularly (he was bi) so he was well trained on humans. We decided to meet up when I was home visiting my parents because he was local to where I grew up (I was in university at the time). He lived on an acreage with his wife (bad I know but I was horny and young lol) so I met him at a gas station in town and followed him back to his house. I had to pee really badly but he made me squat and pee outside so he could watch lol. (Later on I found out he'd have drank it if I offered which I was a little disappointed on missing out on.)
Then we hopped in his truck and he put his german shepard in the back and drove into his field where he laid out a blanket and told me to get naked, so I did. He told me I'd probably want my ass loosened up a bit before taking a dog and I was mega horny so I was happy to oblige. So he pulled down his pants and fucked my ass for a bit while I played with his dog's sheath. After fucking me for a few minutes, he helped me tease his dog's cock and get him excited and I was absolutely leaking. That was my first taste of dog cock but I didn't suck it too much before I turned around and he mounted right away and started thrusting.
I tried guiding him into my ass as planned but he was thrusting and poking around the area so much he poked and found my pussy instead and when he did he thrusted deep and hard. It was really intense and fast and his knot started expanding and I panicked a bit because I felt it was more than my pussy could handle. I was never into stretching my pussy so this was mega intense and a bit painful for me. I tried pulling away but The owner instead came around and stuck his cock in my face and told me to suck... so I did lol. It helped give me something to focus on lmao... he came pretty quick but I was still knotted and he told me he needs to piss. So he started pissing on my face... I opened my mouth and drank some but he directed his stream up to my hair and drenched me then pointed back at my mouth for the rest. I was rubbing myself like crazy and that combined with the pulsating knot in my pussy drove my over the edge and I had one of the most intense orgasms of my life. Then we just chilled while I rubbed my clit and felt puppies being pumped in my pussy while I knotted for a bit. Eventually his dog went to turn and his knot popped out and so did a gush of cum. So I turned around and sucked his cock clean. Then I got dressed and we drove back to my car where I drove back to my parents house with my womb filled with dog cum my stomach filled with piss and dried piss in my hair
said hi to my mom and showered and masturbated like 5 times in a row to what just happened lol.
