The Mage's Tale
Chapter 10
After the long and boring introduction to the farm, my parents and I went around and got to know some of the horses. When we got to the stallions in the barn, the mares outside had already been herded to their own separate barn. The stallions were thus much better behaved when I saw them the second time. There were no semi-hardons to be seen, their thoughts were much more mellow, and they seemed happier to see us. I figured that if I was going to push the limits of my magic, I would need them to be at least a little horny when I tried. So maybe when the mares were somewhere nearby, or maybe I could get some of the mares' scent to entice them with? My cock stiffened at the thought of seeing these monster cocks at full size, and I was careful to shield my thoughts from Dad.
Later that night, I waited impatiently for my parents to fall asleep. I sneaked on down to the mares' barn in my pajamas, with a wash towel in my hand. This seemed like the best way to get some mare musk and have the privacy to try something with the stallions. Upon getting there, most of the mares were asleep, but were light enough sleepers that they woke up upon hearing me. One of them, a brown one with a blonde mane, seemed especially friendly, even presenting herself to me. I found this odd, but since it was what I wanted, I didn't question it. I wiped her pussy with the towel, really working it into the folds. She liked the attention a lot, and got really wet, which the towel soaked up. Feeling a bit sorry for her, I pulled back the towel and left, having gotten what I needed from her. "Hopefully she can get a good fucking soon, she clearly needs dick. I know what that's like." I sighed at that last thought, and as I crept over to the stallions' barn I got harder and harder.
Walking inside, the stallions were in a similar state to the mares, but all four woke up when I got closer to them. I could try my plans with any of them, but the bisexual black stallion with the massive cock intrigued me the most. I introduced myself to him, and he seemed gentle enough, though his thoughts expressed puzzlement. He didn't know who I was or why I was there, but wasn't afraid of me. It was odd, I could get small snippets of thought from the animals, but nothing bigger, and usually it was just feelings. I had definitely gotten more adept at reading men; maybe animals were just different, or maybe they just didn't have as many complex thoughts as men did. I pulled the wash towel with the mare musk out of my pajama pocket and the effect was immediate. The stallion flared his nostrils and I could see his cock dropping from its sheath rapidly. Inch after sexy inch poured forth, seemingly without end. I tore my gaze away from the cock and moved the cloth closer to his face, then looked back at his cock. His cock had slid out what must have been at least two feet long, maybe closer to three, as his glans was resting lightly on the floor of the barn. The absolute monster of a cock was bigger around than my forearm, and I wondered if this stallion could even fit inside a mare. I knew that mares were equipped to take big stallion cock, but this seemed like too much even for them. I couldn't take it anymore, I had to touch this cock, though I didn't really care for the wild eyes that the now powerfully turned on stallion had now. So I tried something that I didn't really think would work.
I concentrated on his cock, letting it fill my thoughts.
I had to really push, focus exceptionally hard on this glorious pillar of flesh before me. It consumed me, I could think of nothing else. There was only this cock, it was the whole world. Finally, after pushing my powers to their absolute limit, I snapped back to reality a bit painfully. My mind reeled from the sudden shift, and I felt a bit unsteady as I blinked away the dizziness. When I could focus again, I felt a massive weight between my legs, and my underwear was stretched beyond its ability to hold. My underwear waistband snapped suddenly, and I pulled down my pajama pants to assess the damage. I was aghast at what I saw.
My cock had been replaced, as I had expected. Though I was not expecting the cock I got to still be a horse cock. And oh boy, what a cock! It was jet black, and only semi-hard, but it dangled below my knees, and I could only barely fit my fingers around it. There was a ring around the middle, about six inches down the length, and the head was slightly flared, with a small tube sticking out of the center slightly. My new balls were more than double the size of my old ones, and had a different texture to the skin. I could tell a big difference in the smell I made too. Interestingly, this cock was not the same size as the stallion's had been before the swap. It was enormous, of course (waistband snapping enormous at that), but it wasn't three feet long. I realized suddenly that because the swap was successful, the stallion now had my human cock on his body. What I saw him packing now was the biggest human cock I had ever seen, easily eighteen inches, and beyond the ability of any human orifice to contain fully. He had inherited my balls too, though they too had swelled to match the stallion's size and virility. He even had my wiry pubic hair. I thought to myself that he likely was better able to fuck the mares now, and I figured that it would be my payment to him to let him fuck a mare with my cock while I played with his for a day or so.
For now though, I wanted to play with this cock, to shoot a big horse sized load right here. I stepped out of my pants, set up my destroyed underwear as a cum rag, then as I was sitting down the rag with the mare musk, I caught a whiff of it. The smell was electrifying, my new cock hardened so fast that I almost passed out. Once it did, I took a good long smell of what had been wholly uninteresting to me mere minutes ago. It smelled like ambrosia, and made me so hard that it almost hurt. I didn't care about the source of it, just how it made me feel. I sat back on a barrel, and played with the massive horse cock I was now packing. It stretched up to my neck fully erect, so I indulged in another fantasy of mine, selfsucking. I pumped the shaft with one hand, teasing the big balls resting heavily on the barrel with the other as I wrapped my lips around the head. I had to open my mouth as wide as possible without unhinging my jaw, but it was worth it. I got to experience the joy of giving and receiving a blowjob at the same time, and tasting my first horse cock. It had an interesting, musky flavor that I quite liked. I kept up with my self love for a few minutes, losing myself in this wonderful dick.
Eventually my jaw got tired, and with my new stamina, I was nowhere close to cumming. I pulled off the juicy, tasty head and resigned myself to simply jacking the big dick off with both hands. As I did so, I unexpectedly saw the stallion reach over his own head and start licking the big horse cock himself. "Damn," I thought, "he is a bit of a slut. I didn't know horses did that." Then he further surprised me by taking my new cock head into his mouth completely, something I couldn't manage to do myself. He clearly had some practice with this, as he gave me an amazing blowjob. Not reading too much into this fact, I sat back and let him suck me to completion. I noticed as I did so that his pasty white human cock was dripping precum all over the floor and I wondered if he would cum from this. I thought back to how I had sucked Dad's dick last night and how I had cum from doing this exact thing. I remembered my dream from the car earlier too and the thought of Dad packing this huge cock and me sucking the cum out of it pushed me over the edge. I pulled out of the stallion's mouth quickly and grabbed my ripped underwear before I erupted in the biggest orgasm of my young life. I didn't know so much cum could cum from one load. I came for a solid minute, painting my chest, my face, my hair, my legs, and the stallion's face (as he simply had to taste). I sat there, barely conscious from the pleasure, stallion quickly lapping up the cum. I knew that if I wanted some for myself, I would need to work quickly. I swabbed up the cum from my legs with my ruined underwear, but it was quickly apparent that it was insufficient for cleaning it all. I let the stallion clean my cock as I scooped up some of the jizz from my face, tasting it for the first time. It was amazing! I thought that the mare scent was great, but horse cum was even better. I paced myself, not wanting another erection, or I'd be here all night. The stallion, however, was very eager, and as he licked the cum from my chest, I heard him neigh and snort, and saw then that he was cumming his first load from his human cock.
