It all started when I was fifteen years old. My family had just gotten a new dog; a male German Shepherd named Buster. He was already a year old when we got him, so he was full grown.

A few weeks later, I had just gotten out of the shower and I was home alone. I was lying on my bed in my bathrobe, rubbing my hairy still-virgin pussy, and I didn’t notice Buster walk in.

I was daydreaming about this boy that I liked when I felt something cold and wet bumping against my mound. I looked up and saw Buster nuzzling into my crotch. At first, I was shocked, but it felt amazing, so I opened my legs wider so he could get a better taste of my pussy.

At first, he licked my panties, making them wet with slobber. I pulled them to the side so he could get a better taste. He started licking harder and faster, by then my clit had come out of hiding and Buster’s tongue found it, tiny but very erect.

When he started to lick my clit, I shivered all over. It was like jolts of electricity were being sent through my body. I started playing with my tits (which were still growing). I knew nobody would be home for a while, so I decided to play doggy with Buster. I took off my robe and my pink cotton panties, then I got down on all fours and started to bark like a girl doggy.

He started licking my face, and I figured since I was a doggy, I should lick him too. I started to lick him when his tongue went into my mouth. It felt so cool, my first French kiss, and it was with a dog.

Buster then moved around behind me and started to sniff and lick my pussy again, so I spread my legs and raised my ass into the air a little. He started to lick harder, and I could feel my pussy getting wet. Just then, he jumped up on my back.

I thought he had gotten tired of this game and wanted to leave, and he had gotten stuck, but I was wrong. I felt something hard start to poke at my pussy, then it all came together. Oh my god! Buster is trying to hump me; he really thinks I’m a girl doggy.

I tried to get away, but it was no use; he was as big as I was and holding on too tight. Then it happened: he hit his mark. All six inches of his swollen doggy cock stuffed into my tight, virgin pussy with one hard push. I fell to the floor in pain; my virginity had just been taken away in one hard, violent pump. Tears ran down my face as Buster continued to pump my tender pussy.

Then, in spite of the amount of pain I was in, I started to cum. Buster started to pound my now cum-soaked pussy harder and faster. Finally, he started to cum; it was amazing to feel the hot jets of doggy sperm being shot into me.

I started to cum again. It’s hard to explain the feeling of my cum mixing with Buster’s cum in my belly. When Buster decided to get off me, his cock pulled out with a loud pop. Then all the cum from inside me came pouring out of my reamed pussy and dripped down my thighs.

Buster cleaned me up, then went to the corner of my room and licked his now limp cock. I lied down on my bed and put my hand on my pussy. I felt my hole; it was so big and stretched out. I dipped my finger in and scooped out some cum. I brought it to my mouth and tasted it. It tasted so good, the perfect mix of human and doggy cum. I sucked my finger dry, then I thought about what had just happened. I couldn’t believe it.

I had just had my first fuck, and had a couple of orgasms because of my dog, and I didn’t feel guilty about it at all. I felt so grown up. I was now a woman, and I had Buster to thank for that. When my mom came home, she told me that I looked different. I just flashed her a devilish grin and patted Buster on the head.

From then on, Buster went everywhere with me. He even joined me at summer camp ... but that’s another story.
