I enjoy it every time, but recently my solo play with Rex was getting a little stale. I wanted more, and different, and quite frankly even the thought of getting caught was no longer giving me that edgy feeling. I wanted bigger. So one day I decided to take my play with Rex out of my shed. I wanted to fine somewhere entirely different. I took Rex back in the woods behind my place, spred out a blanket, and invited Rex to lick me. Soon, I was on my knees, and Rex was pumping away insice my pussy. As I should have anticipated, my neighbor caught me. He is a young guy... his name is Bud... and has a kennel full of dogs. One of the dogs had a gotten out, and Bud was combing the woods looking for him. When he came upon me, he didn't act surprised, or even critical about what I was doing with my dog. He just asked if I had been doing it with Rex for long, and if I wanted a new partner. Appreciating the cool way he dealt with finding me in sex play with Rex, I said "yes." Bud said to meet me in his barn the next afternoon. Right after lunch I went to Bud's place. After I got there he told me to do whatever I typically did to get ready. So I stripped down and massaged my clit for a minute. I knew that would generate a fragrance that might be a little bit of enticement for his dog. As I was friging myself, he came back with a large mixed breed male. He was much larger than Rex. The bog dog immediately started sniffing and licking my pussy, which quickly started dripping for him. Bud sat down in a chair in the corner and just quietly watched. As I stood there letting the dog lick me, I had a small orgasm. My legs shook, and my pussy oozed. Then I felt my juices drip out of my pussy lips. The dog lapped harder as the air began to smell a little musky. I noticed that the large dog's red cock had emerged from the sheath between his legs. My pussy was tingling with excitement... more than it had in a long time. My juices and frangrance seemed to drive the dog nuts. I got down on my knees, and he immediately mounted me... thrusting forward until he found his mark. Once he made penetration, he pounded into me furiously... never stopping, slowing, or hesitating. His front legs seemed to grip my sides. The force of the dog's pounding drove me forward a little. I had to take a few steps forward on my knees. He was strong, and his thrusting was furious. I felt the dog's cock begin to swell within me. It was creating the friction I so much love. Then he pulled almost out... and thrust into me so hard I almost collapsed under the force. That's when I felt his knot enter me. It was large, and I could feel that it was still growing. I felt my pussy lips begin to burn and stretch. He was pumping me more deliberatly then, and I felt the knot move forward until it settled right over my G spot. Ahh... that felt do good! I rocked to add to the good sensations within me... thrusting back to meet him. I titlted my hips up, allowing his throbbing cock to slide through all the sweet spots in my tight pussy. I was crammed full of hard dog cock! I came (nearly blackingout)... and shuddered beneath him. As my head cleared I heard Bud say, "well done." I had almost forgotten he was there. He had just been quietly sitting in the corner... watching me enjoy his dog. "You like being fucked by a dog... don't you?" he said as he knelt in front of me. I just smiled and said, "Obviously." I was quickly learning that I had become a bit of a K9 slut... a nasty, naughty K9 slut. Bud gently ran his hand over my tummy... down to where his dog was still connected with me. Both the dog and I were laying on our sides. Bud began to play with my clit. Feeling the movement, the dog squirmed a bit, sending a new series of wonderful sensations through my pussy and to my brain. Then Bud bent forward and sucked one of my breasts into his mouth as his fingers continued to play on my clit. I closed my eyes and enjoyed all the good sensations. The dog began to try to pull away from me. We were still tied together with his large knot inside my pussy. He was hugely swollen. His tug on my vagina every few seconds was painful, but was tempered by the fact that he was again stimulating my sweet spots, and Bud was giving my breast and clit some really good sensations. After about 15 minutes of Bud playing with me, and the dog still connected to me, I began to feel the knot within me subside. Bud must have noticed. He moved his hand down to the dog's cock and gave it one good tug. It hurt a bit, but the dog popped out. He immediately got up and trotted away. Bud gave me a little kiss on the cheek and said, "It is good to see a woman who really enjoys the pleasure a well-hung dog can give." I just smiled up at him and said, "Thanks for letting me try your dog." "Any time," he said, as he got up and put the dog back in his kennel. I cleaned up and dressed. Then I thanked Bud again. He nodded and said, "Come back any time. I have other large dogs too." And yes, believe it or not, that was it. He never tried to have sex with me in any way. He didn't even jerk off in front of me. I am not so stupid as to think he didn't re-live my experiences later in private... but Bud was a gentleman that day, and each time since.
