As I walked into the barn I noticed it was like any other kind of barn with straw, and manure all over the floor. I stopped in front of the black stallion and stared at him. My cunt felt as if it were swollen open. I bit my lower lip, Thunder stopped his back-and-forth movements and seemed frozen, those big brown eyes appearing to grow even softer.

Standing naked in the semi-darkness. I was afraid to move. But then I did, opening the stall and carefully stepping in. This whole thing seemed unreal, a deliciously evil nightmare.

“Ohhhh, beautiful horse, beautiful...”

Standing to the right, I began stroking the stallion’s sides, feeling his warm flesh, feeling the strange silky touch of his slick hairs against my hand. It was so odd, me standing in the stall, stark naked with this horse panting nervously, excitedly next to me. Running my fingers up and down his sides, I felt the muscles quivering, felt his flesh warming to my touch.

Closing my eyes and putting my free hand to my chest. It was so hard to breathe again, a problem I had when I’m aroused. Was I aroused? Oh God, yes! There couldn’t be any question about it! The sounds, the smells, the touch, everything conspired to drive me into this position.

I moved my hand back a little, caressing the rounded curves of his rump, feeling the gentle stroke of his tail as Thunder neighed and shuffled his forelegs over the stubbly floor.

“Steady, Thunder, steady, yes, that’s it, that’s it, I am not going to hurt you.”

I backed away a little more, feeling the whip of his tail at times against my right elbow. He began pawing again at the ground, snorting and dipping his head up and down as I eased my way back toward his hindquarters. It was only when I kept talking to him, kept touching him gently, that the stud calmed down, twisting his head around once more and watching me intently. That stare made me shiver.

“Easy, Thunder ... don’t move ... that’s it, Thunder.” My heart was pounding so hard I thought it would tear through my rib cage.

I was touching the big, hard muscle of his left hindquarter now, feeling it ripple under my fingertips. Thunder moved that hoof back, stomping down on the hay, moving the straw about nervously, then finally steadying himself as I kept smoothing my fingers up and down, up and down his body.

What was I doing? What on earth was I doing standing naked in the stall with this stallion? Got to leave ... have to ... I said to myself. But some dark force had taken over my soul once more. It was as if I were possessed by some terrible demon out to destroy me!

I moved my fingers down lower, hearing my breathing and matching it with that of the stallions. My knees shook while I felt my full, flexible cunt-lips swell with blood, folding over one another. I paused, leaning heavily against Thunder’s body again and closing my eyes. My clit was swollen, poking up from the surrounding moist flesh and throbbing as if my hand were rubbing against it. I smiled.

“Ohhhh...” I moaned.

I moved as if in some dream state. I felt shamefully close to an orgasm. What’s happened to me? I was simply standing there, touching a horse, moving my hands up and down, dangerously close to his cock. But that was all. I had been no contact with the beast, no touching at all except the innocent caressing against his sides. And yet, I couldn’t deny what I was feeling between my thighs, a hunger that made me tremble at my thoughts. I stopped for a moment and wondered what on earth I was thinking of doing, finding out I didn’t know. I simply wasn’t sure of what to do. It was that force, that thing shoving me on, showing me the way.

“Ohhh...” my breathing became more and more shallow.

My tits were hurting me now, feeling so full, so swollen. And how my nipples ached and itched, begging to be touched, rubbed, pinched! I felt so shaky, not myself at all. The big horse still staring at me, his black nostrils quivering with each powerful snort he took.

“Thunder,” I pronounced his name and felt my flesh crawl around my spine.

I found my fingers moving once more. They were sliding down, down the leg, and around to the sexy curve of his hindquarter. I found myself moving back, feeling the nervous swish of his tail as it jerked back and forth more spiritedly.

“Ohhhh, what am I doing?”

My cunt lips rubbed against one another, fluttering with excitement as my hand traveled around and back until I felt something hot, hot, and strange. I froze once more, my mouth opening. I let out a shudder, gasping for air. A horse’s cock!

“Nice, Thunder, nice!”

It was horrible, really horrible, what I was doing and feeling. I should stop now. And yet, I kept going, curling my fingers and moving them around until I felt his big, coconut-sized sac. Thunder stomped around again, snorting, dipping his head back and forth while his mane fluttered from the violent movements. I drew my hand away quickly, as if I just touched a hot plate.

Thunder moved about his stall, banging his sides against one wall. Then he calmed once more, snorting loudly. Should I go on? Should I touch his big balls and prick once more? The thought of being trampled in the stall just for some stupid horny urge raced through my mind.

“Thunder...” Again I pronounced his name softly, gently, as if he were my lover. And again he calmed, twisting his head, rolling those big brown eyes as if he were telling me, he wanted me to touch his cock once more.

I swallowed hard, raised my hand once more, and began moving it down to the horse’s balls. This time, Thunder didn’t move, his only reaction being a shudder that radiated through his entire body. I saw this and trembled. Opening my eyes and looking back a little, I saw his prick! His cock! His prick was big, so big, so damned big and black, hanging there like some massive funnel.

I stopped once more, my eyes widening with excitement. For a moment, just for a moment, I thought about how something like that would feel fucking in and out of my pussy.

My God ... what am I doing? I asked myself, but I knew what I was doing.

I moved my hand until my fingertips touched the fat, hardening cock. This time, Thunder didn’t stomp. His snorting increased, his hindquarters spreading, moving from side to side. I sucked in another breath, and held it until my eyes saw stars. Then I inhaled and exhaled. I moved my hand up. In a second, I had my fingers wrapped around that big cock, then moving up and down. I was jacking off a horse! I was actually jacking him off.

Moving my fingers up and down, feeling the hard throbbing prick jerk in my fingers. It was crazy, it was insane. It was like I had been propelled into another world where my morals were turned upside down.

I could hear the wooden stall wall groaning under his weight as he pressed against it. I moved with the startled animal, stroking his dick once more, cooing to him – then dropping my trembling fingers to those fat balls one more time.

“Ohhhh, nice Thunder, good boy.”

This time the animal didn’t move. He let out a long shuddering sigh, dipping his head and shaking it, the long black mane fluttering from side to side with the movement. I sighed as well, the tips of my fingers stroking those fat balls. Never had I touched anything like them in my life! They were so hot, so hot and tight. The skin was something like leather, pulled to the tearing point. And yet, apparently, they were sensitive to the touch of my fingertips.

Thunder was shuddering, snorting at me, then moving back and forth, twisting his head around to see me better. When I saw those brown eyes fixed on me, I leaned heavily against his body, my knees threatening to give way under me. What kind of slut was I turning into?
