I'm a stereotypical furry. I have sex with animals. I look at furry porn blogs almost daily. At the time of this story I lived with my parents, who had a Dalmatian (for the sake of privacy lets say it's name was max) . I also was a virgin. They didn't know that I'm a furry at the time, and I didnt want them too, at least before I moved out. So one fateful day I was looking at porn blog and masturbating in my room, when max walked in. He almost immediately smelled how wet I was and jumped on my bed. I got up and locked my door, and we went at it. I got my shirt off and sat on the floor while he licked my pussy. It felt so good.
I had never let him fuck me though. At that point we had only given each other oral sex. But I was really horny, so I decided to let him. After I came. My first orgasm shook me and my cum went all over Max's muzzle, who promptly licked it off. I flipped over, and arched my back to present myself to max. He sniffed and licked, making me moan, and eventually mounted me. It took a while for him to get in me, but it was so worth it. His cock was so thick it stretched my virgin walls. I came quickly, an orgasm shaking my body. But Max's pace never slowed, it just kept going.
I had another orgasm before I started to feel his dick growing. I had read online that dogs have knots that tie them to their bitch for up to an hour. I tried to take his cock out but it was too late. His knot was full size, and his hit cum shot into my vagina. The pressure on my clit was overwhelming, and I immediately had an orgasm. His cock was already huge before his knot grew, and now that it had, it felt like someone was trying to shove a semi truck up my rear. I screamed at the pain of it, even though it was extremely pleasurable at the same time.
It was at this point my mother walked in. I was too busy having orgasm after orgasm from max to notice. After about half an hour Max's knot had deflated enough to pull out, and he started cleaning himself.
I collapsed on the floor, while both mine and Max's fluids ran out of my body. After a minute of panting, I sat up. It hurt, to say the least. I reached back to touch my pussy, and looked at my hand. There was mostly cum, but also a little blood. I wasn't that surprised. Suddenly, I heard my mother moving behind me. I nearly fainted. "Mom! I-I'm sorry I didn't- it wasn't- Im sorry!" It was then I realised she had pulled her pants down and was masturbating. My jaw dropped.
She laughed. "I have been fucking that dog for years now, you have no reason to be embarrassed." I was shocked. "Does dad know?" I asked. She nodded. "He was the one who showed me." After some convincing, me and her Sat down and talked about what we've done, how we learned about it, and when we started. The most vivid memory of that conversation i have is mom saying, "your cum isn't the only gals fuild he craves."
