I run my padded fingers through my belly fur, feeling the softness. I pant a little, squirming as I look in the mirror. My purple eyes look back at me. It had been a stressful day at work and I just want to relax. It had also been awhile since I had last gotten laid. I wasn't much good at masturbating, never really could get off from touching myself, but that didn't mean it didn't feel good. So here I am, desperate for touch, desperate for a fuck.
The fur on my thighs is wet and sticky even before I can start digging around in the drawer next to my bed for my vibrator. I curl my tail up as I let my pierced tongue hang out the side of my muzzle. Where did I put that thing? Sure, it's small, since I live with my older half brother, and I keep my toys rather discreet, but it still couldn't have gone anywhere.
I yelp in surprise when something cold touches my hot slit. I turn and look down at Max, my brother's German Shepherd. He's a pure bred, from a really long line of police dogs, so my brother never saw any reason to get him neutered. I realize I hadn't closed the door all the way like I thought I had, and he was attracted by my scent.
He sticks his nose against my cunt again, taking in deep inhales. I try to push him away, to get him out of my room and back out in the living room where he knows he belongs. But he forces his nose back at my crotch. Then he licks my furless slit. Without really meaning to, I give a little moan. Boy, that felt good.
"Max, out!" I try to be firm with him, but my voice cracks. He must sense my desire because he starts licking me over and over again with quick little laps of his big, hot tongue. A shiver runs through me in pleasure. That feels really good. Well, what could be the harm in letting him lick me? I can't find my vibrator, so Max's tongue is the next best thing.
I quickly rush to the door to look around, just to make sure my brother wasn't home yet. I knew he was going to be home soon so if I was going to do this, I had better do it fast. Max follows me and again shoves his nose under my fluffy tail. I give a little whimper as I close the door. I then go over to the bed and sit on the edge, facing Max.
My heart pounds as he comes over and tries to force his way between my knees. I'm still not too sure about this. Max paws at my legs, and I finally spread my knees. He stuffs his nose against my hot slit, the feeling of his cold nose makes me shiver. He proceeds to lick furiously, long, hot licks all over my cunt and inner thighs. I moan as he keeps going. My hips make little motions. My hand goes up through my fur and finds one of my hard nipples. I roll it gently, my moans and whimpers getting louder.
And then Max puts his front paws on the bed, and I feel something hard poking me in the leg. He's trying to mount me. I think about for a minute. It's not like he could get me pregnant, even though it's something I want at this point in my life, being at the perfect age. Scared, but just dying to get something into my burning cunt, I slip down to my hands and knees, my tail curled up for him. He immediately mounts me, his front limbs gripping me around the hips hard. I feel his cock poking me on the butt and thighs, so I go down to my elbows, which brings my pussy just to the right height. Not a thrust later and I feel a smooth, hot pencil shove into me.
He starts humping incredibly fast, panting hard. I immediately feel that thin hard rod swell inside of me. The feeling is so amazing I very nearly howl with pleasure. He keeps humping, his back legs dancing a little with the speed of his thrusts. I can feel the heat of his cum against my cervix, and it feels so wonderful, almost relaxing. His cock is filling me up, stretching me, but it doesn't hurt at all.
I moan and whine and pant, my body going crazy with the lust. My claws dig into the carpet as I feel every last inch of Max inside of me. His big, furry balls smack against my clit, making it even better. I can feel my body reach climax, all my muscles clench up. I cry out in the intense pleasure. "Oh, good boy, good boy!"
Just as I come down from my orgasm, I feel an intensely pleasurable swelling inside of me. I pant with both surprise and ecstasy. I had forgotten about the fact that Max would knot. But that doesn't matter at the moment as I can feel the heat of all his cum squirt into me. I keep moaning as I get filled with his seed. I can't help but wiggle, grinding my hips. I realize then that with the knot inside of me, rolling my hips side to side makes the knot rub my g-spot.
As Max turns, trying to pull out, I grab his hind leg. He stands still after that. I wiggle my hips some more, feeling that wondrous knot inside of me. I feel sad the wild, bestial humping hadn't lasted longer, but this is pretty amazing, too. I can feel him still squirting into me, just filling me with the hot cum. Hot little drips run down my clit. As I pant, I stroke Max's leg, my voice full of pleasure. "Good boy, Max. Oh, good boy."
Finally, after about 10 minutes, I get onto my hands and let go of his leg. I lean forward slowly, feeling that glorious knot pop out of my pussy, along with his massive swollen cock. Instantly, all his hot cum gushes out of me, pouring down my thighs and slit. I moan again with the feeling, not really thinking about how I was going to clean it all up.
I stand up, more of his cum dribbling down my legs. Max is in the corner, licking myself. I get a peek at what it was that had been inside me and felt hot with a blush lost in my white fur. It was bigger than anything I had ever taken before, and yet it had felt so amazing.
"Have you turned to being a dog fucker now, little sis?"
