| I am not much of a writer as some folks here are so please bear with me as I try to relate my first time taking a ponyís cock.It was on a Saturday, I got to my girlfriend Terri's house at about 9:00 Am. She has a small farm with some horses and a Shetland pony. She had some coffee made and we each got a cup and sat on the front porch talking about our upcoming adveture. Terri's husband had gone upstate for the weekend to do a job so we had all weekend to ourselves. Terri was really horny and so excited to get started. I have to agree that I was too and very wet, and just a little nervous. We discussed what we needed to do, and after we finished our coffee, we went over to the barn. The pony was in his stall and we knew what to do. We got some rope, a haybale and some horse blankets to put on top of it for padding. Terri led the pony out of his stall and we started preparing him for sex. We put a harness on the pony and tied him up in the alley way. We tied his head down so he couldn't thrust and I fashioned a sling for his hips for just a little extra protection. We played with the ponys cock until it slid all the way out of itís sheath. I was a beautiful sight, so big and long. It was really raising our excitement level as we washed it to get all the slime off of it.We both got our clothes off and Terri played with my body until I was moaning. Next, Terri returned to the pony and checked his "equipment" as well. He was securely tethered in the alley but he danced around a bit as her hands went to work trying to bring forth his erection again. After a few minutes, she had coaxed about four or five inches of his penis out of the sheath and it was at least two inches across. She leaned down and took what she could into her mouth. Due to it's girth, she could only manage two or three inches of the end, and her mouth was stretched as wide as I had ever seen it. The ponys cock continued to grow and Terri turned around and put the huge head against the swollen lips of her pussy, the stallion was at least thirty inches long and three and a half inches around by this time.She felt he was ready, and I could see her pussy juice on the stallions cock. Terri used a whole tube of KY jelly and squeezed most of it up into my willing pussy and what was left she spread on the ponyís massive cock. I crawled under him and positioned myself on the bale. His cock was resting on my belly as I stroked it and slid further up the bale to position the tip against my well lubed pussy. I was in a rush to get the pony inside me and Terri had to caution me to slow down and take my time. She told me not to take any more than I was absolutely sure I could handle as she didn't want to have to rush me to an emergency room and explain what had happened. That thought sobered me up a bit and I slowed down. I slipped the pony's cock up and down the gap in my pussy lips a few times and positioned it for entrance. I held it there for a few seconds, then started working my way a little at a time, toward the bottom of the bale. There was a little resistance before the head entered me about an inch and Terri said she could tell by the tightness of my facial muscles that I was already stretching as far as I ever had. It hurt a little but, I had made up my mind I was going to make this work, somehow.The pony started getting restless, wanting to thrust into me and Terri stroked his back and flanks to calm him down. I had worked two or three inches in, and I had relaxed a little as my pussy learned to accommodate this huge intrusion. I continued to stroke the shaft as I moved down to take a little more and, suddenly, the horse pushed forward another two inches in a single thrust. I groaned loudly and Terri was concerned that I had been hurt but it was soon apparent to her that the groan was of pleasure at being so filled and I started rocking my hips to lessen the depth of the pony's thrusts while allowing his penetration to deepen only slightly each time. The pony was dancing around in agitation and obviously wanted to get on with the business at hand, so Terri petted and soothed him as best she could and I slowly worked a little more into my body. By this time, the lower portion of my belly was already beginning to bulge out slightly from the mass of firm flesh within and I could see my progress directly as the bulge moved ever so slowly up my stomach. I took about 12 inches before I groaned out that he had hit bottom and was pressed firmly against my stomach and I couldn't take any more length. Terri said she could clearly see the entire length outlined on my belly as I released my grip on his cock, and let the horse set his own pace.I had an incredible amount of the animal's length into my depths and I let him start fucking me at his own pace. I told Terri he was really hitting bottom and stayed far enough up the bale so that the sling prevented him from going any deeper. I couldn't believe what I was feeling. I was being f***** completely by a full grown pony and loving every inch of it. My head thrashed from side to side as he repeatedly flicked his hips and strained against the ropes of the sling wanting to release his seed deep into this strange but hot mare. I was moaning and calling out from the fullness of my vaginal cavity when the pony suddenly let go. With my pussy completely full of pony cock, there was no place for his cum to go but completely fill my pussy. I could feel his white hot cum being pumped into my pussy and flooding it full. A small amount squeezed between his penis and the walls of my pussy and started pouring fourth onto the blanket under me. I started cuming and the lower part of my body thrashed beneath the pounding of my four legged lover. My hands went to my pussy to complete my own monumental orgasm. Terri held me, rubbed my breasts and stomach, as I shook violently from the waves of my orgasm shooting through me. The pony must have cum for a good 20 seconds and and then his cock fell out of me. I was still convulsing even as Terri helped me out from under the pony. My body was so limp from the violent orgasm, that I just layed in her arms for a while, to weak to move.
