I looked at Cowboy’s cock in amazement. Within the past hour he had gotten three hard-ons. I had no idea that he would be this horny today. Cowboy kept nuzzling at me, he couldn’t understand what his mate was doing. He had his harem now, Lady and me. I couldn’t disappoint Cowboy. I had already let him "mount" me once. He was used to breeding his mares twice in a session, and this time would be no different for him. Cowboy began to push against me, wanting to mount. He was again slapping his erection against his belly and snorting at me. I slipped my bra off again and slipped down to my hands and knees. I quivered in anticipation. As soon as I was down, I presented my cunt to Cowboy as if I were a real mare. So what if I didn’t have fur, or hooves, or a tail? So what if my face was different? I was here and I was a receptacle for Cowboy’s sperm.

The stud mounted me and plunged his cock at my cunt. Unfortunately he missed and buried his cock into my virgin asshole. I squealed in pain and terror and tried to pull away, but Cowboy gripped me with his hooves. He tried to pull out to thrust again, and found himself stuck. Now Cowboy panicked. He began to pull away hard and I knew if I didn’t relax, Cowboy would tear me in two. I relaxed as much as I could, and Cowboy slipped out of my anus with a grunt and a pull. He plunged again, and this time sunk into my cunt. I was sopping wet, and already near orgasm from masturbating, and I moaned with pleasure as Cowboy filled me. He stroked in and out firmly, going at a middle pace. His thick cock rubbed against my clit as he thrust in, and his cock pressed all of my vaginal walls wider. He kept his thrusting up for nearly 10 minutes, and I came, screaming orgasms, three times. I had found myself thrusting back on Cowboy’s cock, taking as much of him into me as possible. It was almost like having sex with my husband, although his cock had never stayed hard this long, nor had he ever filled me like this. Suddenly I could feel Cowboy’s cock shudder in me, and I was filled with his seed. He came the longest this time, staying perfectly still on me for almost two minutes, filling me with cum. I came again as I felt his cum fill me, a warm liquid of life. I could feel a combination of his cum and my cum flow out around his shrinking cock and as soon as he dismounted me, I reached around to taste the liquid. As I caught some in my fingers, I felt something brush against my pussy, and I turned over in horror.

Standing directly behind me was the man who had dropped off the mare about two hours ago. His pants were tented with an erection and he had an amazed look on his face.

"Do you always fuck your stallions?"

I shook my head and tried to cover my body. The man had taken my clothes and moved them. I couldn’t see them anywhere.

"I came back, to tell you some things about Lady. I heard you in here. I couldn’t help but watch." The man smiled at me, and I could tell that his motives were innocent. He hadn’t even taken his cock out to masturbate. He had just been dumbstruck by the sight of a stallion mounted on a woman.

"Well, no harm done, I guess." I said huskily. I was ashamed of what I had been caught in the act of. Then I looked at the man. A look of pure admiration was on his face, and he unconsciously fingered the zipper on his pants. "Aren’t you going to take that out?"

"W..w..wh...what?" The man blushed and I reached over and undid the zipper.

"It must be bothering you." I gently stroked the rock-hard cock and the man breathed heavily. "My name is Beka . . . moan that if you have to moan anything."

"I’m Jeff," he grunted. Jeff began thrusting against my hand and I marvelled at how much he was like Cowboy. Cowboy stood in the corner of the stall, eating some hay that was there in case Lady hadn’t objected to a second breeding. I raised myself onto my knees and firmly wrapped Jeff’s cock in my breasts. He began thrusting like an animal, and I licked the top whenever I got the chance. Jeff reached down and slowly pressed me to the floor of the stall and kept fucking my boobs. I played with my nipples as he did it, and licked at his cock head whenever it got close, then suddenly I found his whole cock in my mouth. Jeff plunged it in and out, moaning my name and grunting. His cock swelled in my mouth and I thought he was going to blow, but Jeff kept plunging in and out. I sucked and licked at it, hoping he would blow before my husband got home. Then Jeff roughly thrust his hand into my cunt. I was still dripping horse cum, and I was aroused by the situation I was in now, and Jeff could tell. His thumb flicked across my clit and first two then three of his fingers plunged in and out of my cunt. I closed my eyes and moaned softly, and then suddenly was aware of Jeff’s cock leaving my mouth. I had less that five seconds to think about it before it was firmly thrust into my cunt. I gasped as it entered. It was bigger than my husband’s, and it throbbed more warmly. I screamed as I came, Jeff’s harsh thrusting sent me into yet another massive orgasm. Jeff’s fingers found my nipples and pulled and twisted at them. I couldn’t do anything but thrust back into Jeff’s hips and moan as orgasm after orgasm rolled over me. Then Jeff screamed. For the second time that day I could feel myself being filled with cum and I moaned Jeff’s name. Jeff left his cock in me until it was totally limp and we had both recovered our breaths. He pulled out of me and I could feel our combined juices flowing out of me like an exotic cocktail. Jeff lowered himself to the straw of the stall and drank all the juices which came out. I had hoped he would give me another orgasm, but he stood up and offered me his hand. He hugged me, roughly.

"I am sorry for my indiscretion. I shouldn’t have let myself in and I shouldn’t have watched and I definitely shouldn’t have taken pleasure with another man’s wife." Jeff dropped his eyes remorsefully, then pulled up his pants and stuck his already-rehardening cock back inside. He handed me my clothes, which he had put on a chair outside the stall. After helping me dress, Jeff and I led Cowboy back to his stall. As soon as Cowboy went back into his stall he started to doze, and I knew he would be ready for another round the next day.

I walked with Jeff out to his truck and hugged him. "Thank you for the wonderful sex." I whispered. Jeff looked at me in shock and I giggled. "My husband and I have an open marriage. I’ll tell him about this, and he won’t get mad, but I would appreciate you not saying anything about seeing me with the stallion. I’m going to tell him that we were both overcome by passion watching the horses breed that we let ourselves go." Jeff smiled and nodded. "And perhaps you can come back for another time, and I could introduce you to my husband in a whole different way." I winked at Jeff and he chuckled. I watched as he got in his truck and drove away, and I marvelled at the light flakes of spring snow that were falling. They were the last fall of the year and I hoped that I could have one more round of snow sex when my husband got home.
