Hello, I am a 24 year old woman, and I'd like to share with you and experience I had a few years back. Let me start by giving you a brief description of myself. I have brown hair, blue eyes, and I'm 5'5", and 116 lbs. I was house and dog sitting for my aunt, who was taking a two week vacation. She has a chocolate Labrador. My boyfriend and I had just broken up, and I had moved back in with my parents. I was nineteen at the time. The second morning of my stay at my aunts house, I woke up and went down to the kitchen for breakfast. I made some toast and poured a glass of juice, and sat down at the breakfast nook. I was looking at a magazine when suddenly, I felt something cold on my crotch. I didn't have any panties on, just a night shirt. It was my aunts dog, Tree, sniffing and licking at me. I screamed and yelled at him, and he took off running. I finished my breakfast, showered and dressed for work. When I arrived home from work, I let Tree out and sat down on the sofa,slipped off my shoes and looked at the paper. It wasn't very long before he was barking to come back in. I let him in and fed him and gave him some fresh water, and resumed my reading. He soon came in and sat down on the floor next to my feet. I was engrossed in an article when I felt Trees tongue gently licking my foot. It felt very soothing, so I let him continue. I soon positioned my feet so he could lick the bottom of both of them. He really seemed to be enjoying it, and began licking my ankles. I thought about what happened earlier, and was starting to get aroused. I hadn't had sex in over two months. I pulled my skirt up, and began to lightly massage my clit through my pantyhose. It felt very good, and I already was soaking wet. I spread my legs and began rubbing faster. Tree must have smelled my fluids, because he stood up and began sniffing my vagina, and his tongue began licking my hand. I moved my hand and he began licking my vagina through my pantyhose. God, it felt so good. And I was very excited by then. I stood up and quickly pulled off my pantyhose and sat back down, spread eagled. Tree immediately started to lick me again. He licked me from my butt hole to my clit, very rapidly. My hips were bucking uncontrollably. It wasn't long before I began to climax, screaming in ecstasy. When I was finished, I pushed his head away. I was very sensitive down there. Tree looked at me with his sad eyes. I said to him "what's the matter boy?" I looked down at his penis and it was red and sticking out slightly from it's skin. It was quite a bit larger in diameter than my ex-boyfriends. I reached down, and touched it. It was slippery as I grasped it and gave it a few strokes. It began to stick out further and Tree began to pump in my hand. A little fluid had began to leak out the tip. I started to wonder what it would feel like inside of me. I stood up and then layed back on the coffee table. Tree immediately hopped up and wrapped his paws around one of my legs and started humping. I grabbed his legs and pulled him up and spread mine wide. Tree began humping again, but he was poking me all over, not finding my vagina. At one point, he was touching my butthole. I slid my bottom forward a little, moved my legs up and wrapped them around him and then I felt his penis at my opening. As soon as Tree felt my warmth and wetness, he started to pump it into my vagina. He started slowly at first then made long hard thrusts to get it all the way in. He started pumping me very rapidly then. He must have pumped me for over 5 minutes. I felt something pushing against my vaginal lips, then suddenly it slid inside of me. It was his large knot, and he slowed his humping, just barely pulling his penis back and forth. I felt his dick throb and jump inside of me. He was pumping his cum deep into me. I felt his sperm start to ooze out of me, and run down my crack and onto the coffee table. At one point, he tried to pull out of me, but it hurt very badly. I held him and rubbed his ears, and he relaxed. We were stuck together for almost twenty minutes, finally I felt his cock get smaller and when he pulled his knotted cock out, his sperm ran out of my pussy and ozzed down my ass over the table and on the carpet. I quickly got up and cleaned up the mess. I had more fun with him during my stay, but the first time is the one that is the most exciting to me.
