My family have always loved dogs and I remember I've always been surrounded by them. At this time my family and I had two dogs, Toby and Ruffus. Toby was an schnauzer, he was black, small, energetic and quite aggresive. Ruffus was a Labrador, he was also black, and although he was also energetic, he wasn't aggresive at all (this is key to how things turned out).

Toby and Ruffus came home as pups, so I watched them grow. I loved playing and spending time with them.

As they grew, I started noticing certain behaviours. They would lick their dicks; their tips would stick out; they started humping and getting more curious in general. And now, Toby (and that's why it was important), started humping people. He used to hump legs, if you were sitting on the floor or you were ducking, he would hump you too. If you tried to move him away he would get MAD. It was actually a problem we had with him. Neutering him was an actual option my family considered.

My horny ass just started getting curious about it. At first I didn't really think about it, I was just curious and got my attention. I started paying much more attention to everything they did until it was the only thing that I could think about.

One day I was just HORNY, pulsating cunt horny. So I was just watching some porn, fantasizing (not beast... yet), and touching myself.

"Ly!! Come take the trash out please" my dad shouted.

So I stopped masturbating (still fucking horny) and went to take out the trash. Toby was outside the door of my room, and I saw his cock was HARD. He was licking it. And that's when my first intrusive thought kicked in. His cock just got fixated in my mind.

I went downstairs to take out the trash (still thinking about his cock). He was small, but he was fucking hard, and that's what got tattoed in my memory. I took out the trash and saw Ruffus also licking his shaft. On my way back I saw Toby humping a pillow in the sofa. I finally got in my room, locked the door, and immediately started touching thinking about Toby. I actually started fantasizing with him and started wondering if it was possible to do it. I came and felt GROSS, I swore to never do it again and to forget everything about that. But I just lied to myself, I touched myself all the week to that thought.

The next week I called Toby into my room and started petting him. I called him because I wanted to massage his cock, but I was hesitant, I didn't know if I should've done it. I finally started petting his side stomach and slowly, little by little, made my way to his cock. I stroked it and caressed it. I also grabbed his balls, and in general just touched his maleness. I started doing this frequently, sometimes I did it in my room, sometimes I took him with me to the bathroom, but it became dialy routine. I started letting him get curious with me and do what he wanted. Before, he used to try to sniff my crotch and hump my legs, or hump my arm when I was sitting on the floor, and I would just stop him (and run because he was nuts lmao). But I started letting him do all that. One day in our routine massages, his cock slipped out. I licked it hesitant at the beginning, but then I just let myself go and sucked it. I kept bringing him to my room or the bathroom, but know I would position myself on fours so that he could hump me, I liked the feeling of him humping my ass, I did this with clothes. Kept sucking his cock.

Eventually I just wanted to straight get fucked by him. So I just started getting naked and on fours. It took a while but one day we finally figured how to do it.

I was horny (lol) and I knew I wanted to get railed by him. I got naked and on fours as usual. He started sniffing and licking my pussy. His tongue felt amazing, it was warm and humid, his tongue liked to go between my pussy lips. He also licked my asshole. His cold, wet nose and beard (is it beard? lol) made me tickle. I could feel how he was preparing to breed me, to make me his bitch. All I could think was «JUST FUCKING DO IT! MAKE ME YOUR BITCH». He was really energetic, licking me, turning, humping me. I felt his energy. He grabbed my hips and my ass diagonally trying to mount me, but he was sideways so I tried to reposition and walked away a little, he got fucking ANGRY, he growled at me furious. I got scared and stopped moving until he stopped growling. I was actually scared, but that made me really submit and feel like his bitch, which, in the end I was. When he stopped growling I slowly changed my position for him to fuck me. I spreaded my legs wider, lowered my ass, put my chest on the floor and waited. After a few tries he finally mounted me and started humping me, and then «FUUUUUUUUCK!» he nailed it. I felt so overwhelmed «Omg, what am I doing???» «Am I really doing this?». I was trembling and whining in pleasure, fear, hapiness, sadness. I had no mind, where was my mind? He fucked me so frenetically, feeling his thrusts made me go crazy. His cock was not big, but he still felt so good. He probably fucked me like 40 seconds to a minute, it wasn't long, but boy it was good. When he finished he just pulled out and I felt his cum spurt from my pussy as he pulled away. He came not a lot, but enough for me to feel some inside of me after he pulled. He didn't knot me either (I didn't even know what a knot was, after that I started looking for dog porn and learnt all that). But when he finished with me, I just wanted more, I begged him and stayed there for so long hoping he would do it again, he tried to mount again, but it didn't happen again that day. We were still unexperienced the both of us. But that day he made me his bitch, and I felt so happy and so femenine. And I lived the rest of his days (and Ruffus) as their bitch.

After Toby made me his bitch, I figured I should also be Ruffus' bitch.
