I was minding the store for my friend Heather. The store being a small but successful stables. She looks after rich people's horses. She was in hospital having fractured her hip, you guessed it, falling off a horse. She has an assistant, Katie, who was doing a good job of holding the fort, but today she had something important to do elsewhere, so I had been asked to stand in. I am not at all horsey, it was just a case of someone being present while one of Heather's charges, a young filly, was being 'serviced' for the first time. The stallion would be brought to her, do the business and that would be it. No more than taking in a parcel for a neighbour. The horse box from the stud farm arrived, driven by a really fit young guy. He was accompanied by an equally hunky mate. Studs from the stud farm. The stallion was unloaded and and introduced. He was Max. A huge black stallion with wild eyes. He was led to the paddock where his unsuspecting bride was. I presume that he could smell her as soon as they arrived, he was very frisky and his massive horse-cock was dangling beneath him. He was up for it, but the filly was not, she refused his attentions. "Leave her to get used to him." Advised Steve, the head… what? Ostler? Wrangler? Pimp? I said that I was no expert. "Any chance of a cuppa?" Asked Steve. There was. I was in no hurry for them to leave, I was feeling as horny as the stallion. I made the tea, flirting outrageously with both Steve and Paul. I fancied them both. They were not slow in picking up my signals, perhaps they could smell my arousal like the stud had smelled the filly, Heather had assured me that she, the filly, was ready. "Just let nature take it's course." She had said. But nature, in the the shape of the filly, was not co-operating. I made more tea. Would there be time to show the silly cow, sorry, silly filly, what was required? But which of the two handlers? Perhaps both, it would not be my first threesome. My flirting became more direct. "What happens if he can't, you know, do his thing?" I asked. "There are two options, artificial insemination using his semen, or we could tether her so that she has no choice. But Max can be a bit of a handful when he's arroused, let's just hope he can charm her into it." Explained Steve. "How do you collect the semen for the artificial option?" I asked. "How do you think?" Grinned Steve. "Would you like the job?" He continued. "Do you think you could handle it?" I think that I actually blushed. "Is that really how you do it?" I asked. Paul chipped in; "It's one method, but the one we use is the artificial vagina method." I was pretty sure that they were making this up, but by now I was gagging for it. This could only end one way. Preferably 'three-way'. They explained both techniques, which they assured me were true. The manual stimulation method involved fitting a very large condom and quite literally, wanking him off into it. The other method is getting the stud to mount either a dummy horse or a tethered mare, but diverting his cock into the artificial vagina. My knees were buckling, I was determined to fuck both of them, but business came first. "We'd better tether her then" I stammered. The two of them controlled the stallion while I led the filly inside and tethered her as instructed. Then they fetched the stud. He needed no encouragement to mount the filly, but both the men had to hang onto him. He was so excited that he missed his target and instead ejaculated a massive load onto the floor. There was a string of expletives from the men. The dragged the stallion, now more manageable, back outside. When they returned, Steve said; "He should be ready to go again soon." I was ready to go now, no more tea. I pulled his face down to mine and kissed him. He put his hands on my arse and pulled me against his erection. When the kiss broke, I reached out for Paul and kissed him. The three of us stood in the barn, kissing and groping, Steve rubbed my cunt through my jeans while Paul went for my braless tits. I had a hand on each stiff cock. We were interrupted by a loud crash, shaking the building. My two handfuls disapeared as their owner's ran outside to investigate. Max was charging the side of the barn, he was ready for his seconds. I felt cheated, I was at least as ready for it as Max was. But the boys were professionals, business came first. They led him in. Or rather, he led them. He went straight to his target and mounted her. Steve hung on to his bridle while Paul used all his strength to keep the filly in position. Max's cock stabbed at his target. "Help him," shouted Steve. "Guide him in." I wrapped both hands around what was undoubtedly the biggest cock that I had ever handled, or ever want to, and guided it into position. The mighty thing entered, causing the filly to bray like a donkey as the thing stretched her virgin sheath. Two violent thrusts and the job was done, Max dismounted, his spent weapon flopping loosely. He was docile when the boys led him away. "Is that it?" I asked. "Probably not," said Steve. "He's usually good for at least three, give him time." At least three! Where have all the good men gone? "My turn then?" I asked sweetly. "You bet, is there a bed or something?" He replied. There was a couch thing in what Heather called 'The office', but I had other ideas. "I want it here, do me like she was, tethered." They looked at each other in amazement, I stretched out my arms, wrists together. There was no shortage of rope in the barn. Steve expertly tied my wrists together then led me into the stall alongside where the filly was still tethered. He tied me to a rail in a position that forced me to bend. He pulled my teeshirt from my jeans and pulled it up over my head and down my arms where it stayed, against my tied wrists. My tits hung free. He fondled both before unzipping my jeans, pulling them and my knickers down to the top of my wellies, effectively hobbling me. He explored my arse as thoroughly as he had my tits, stroking, fondling, squeezing. Then he reached down between my legs, finding my stiff waiting clit. A little rub and then he traced a finger slowly between my wet lips, over my perinium to the pucker of my arsehole, pressing with his fingertip. I tensed up, clenching my arse, reallising for the first time the situation that I'd put myself in. Helpless, at the mercy of two strangers. They could do anything they chose, I was tied, no-one could hear me scream. I wanted, perhaps even needed, to be thoroughly fucked, but not buggered. I enjoy anal play, giving and receiving, I like my hole to be touched and licked, penetrated by a finger or a tongue, but not a cock. That was a breach too far, it hurt. A big one hurt a lot. You might be thinking that I was missing out, that I had never been sodomised by someone who knew how and you may be right, but at that time, I had tried it and I didn't like it. I heard Steve unzip. He placed both hands on my buttocks and pulled them apart, then I felt his cock nudging my entrance. The right one. I groaned, a mixture of pleasure and relief as his cock slid easily, balls deep into my dripping, hungry cunt. Considering the highly charged atmosphere, Steve's fucking was surprisingly controlled. He shafted me with long, deep strokes, too slow for my needs at the time. His hands seemedto be everywhere, holding my hips, cupping my buttocks, his fingerstips on my distended cunt lips, touching his wet shaft as it emerged, then they were cupping my tits. Standing alongside, watching his mate fucking me, was Paul, his erect cock poking through his flys, wanking, priming it ready for his turn. Steve increased the pace, now it was working for me. Gradually, his strokes became shorter but faster, until he was banging me like a drum. Then suddenly he stopped, buried deep inside, pulling me onto him using my hips as handles. I could feel his cock pulse inside me, heralding his climax. He withdrew, made several short stabs, then grunted as he discharged deep inside me. I pictured Steve's spunk gushing into me. Some women claim that they can feel it, I can't and I'm not convinced that any woman can, but there is little doubt that it's happening, his jerks and moans guarantee that. There is delicious violence about orgasm. Steve was spent, his convulsions subsided and I felt him soften. He slipped out and moved away. His place was immediately taken by Paul. He seemed to have no qualms about pushing into a used cunt, sliding deep, using Steve's cum as lubricant. His fucking was less controlled, rougher. His big rough hands felt for my wildly flailing tits, staying their movement. I had not come from Steve's fucking, I rarely do when I'm being fucked from behind, I need my clit to be rubbed for that and my hands were tied. "Rub my clit," I demanded. "Make me come." Paul was happy to oblige, easily locating my slippery, quivering bud. It did the trick, I came powerfully. My knees buckled but Paul supported me until my spasms stopped, without missing a stroke. Whether by accident or design, he came soon afterwards, adding his generous contribution to my already well-filled cunt. I felt quite sad, it had been frantic but exciting, now it was over. I could not have been more wrong, Steve almost pushed Paul aside in his eagerness to re-enter. This time he lasted much longer, pounding me until I was panting with exertion. Again his hands roamed freely and I loved it. Again Paul was wanking vigorously. I needed to come again, I was so close but climax was evading me. Without warning, Steve pushed his thumb deep into my arsehole, using the triple cocktail from the three participants, two parts spunk, one part cunt-juice. I screamed in surprise, but came instantly, losing control of my limbs. I fell to my knees on the rough floor, this time my fucker was unable to catch me and he cried out as his cock slipped out. Seconds later I felt his hot cum hit the back of my neck, subsequent spurts painting my back. In the adjacent stall, the filly looked down at me with those sad brown eyes. They helped me back to my feet, Paul was ready to go again, did I want it? Silly question. He pushed back in. This time he lasted much longer, maintaining a steady rhythm, working steadily to his climax. His hands wandered. Like Steve had done, he tried his luck with my anus, this time I reacted quickly enough, clenching my arse to shut him out. I looked back at him over my shoulder and snapped; "Not that, just fuck me." He honoured my request, instead reaching beneath to find my clit and rubbing it. I came again. At last he reached his, gasping as his cum changed ownership. He staggered back, breaking the connection and I went down on my knees again. When my breathing returned to normal, I looked back over my shoulder. Paul was pulling up his jeans, Steve was already zipped up. "Is that all you've got?" I teased. "Official tea break." Returned Steve. "No chance," I said. "Cock first, tea when I say so." Steve held up an imaginary rule book and pretended to read; "Rule 5b: No client is entitled to more than four fucks without providing a fifteen minute break." "I've only had three, coming on my back doesn't count, I'm not making you tea." He shrugged. "Stay there then, we'll make our own. Where do you keep the kettle?" And they started to leave. They had won. They untied me then Steve untied the filly. "What are you doing?" I enquired. "Turning her loose with Max. Now she has had it once she might decide that she likes it." That was true, it had worked for me the first time that I had it. They led the filly out. I started to rearrange my clothing. I pulled my knickers up and reached for my teeshirt, but on impulse, decided to leave it off, then decided to dispense with my jeans as well. I wanted more if they had it in them and naked flesh would be an encouragement. So, leaving my outer clothing in the barn, I went to the office wearing just wellies and knickers. I left them on because, skimpy as they were, they would provide a kind of drip tray for what was still leaking out. The officehad a window overlooking the small paddock, the filly trotted straight over to Max and nuzzled him, then turned her back on him. He had a good sniff, his nostrils flared and his upper lip curled back. His dangler stopped dangling, he mounted the filly and without any guiding, rammed it straight up her. She whinnied, but stood for him as he pumped her. It was all over before the kettle boiled. Either she had decided she liked it, or watching me getting the same treatment from my two studs had convinced her. I poured the tea, but it went cold in the cups. My nudity had the desired effect. I quickly lost the knickers and the guys their clothes as we got to know each other better. I was able to carry our a full inspection of their cocks, both manually and orally, then they layed me out on the couch and took turns to fuck me one last time. We were disturbed by the sound of an approaching car. Katie! I had forgotten that she was coming back. In the absence of Heather, she was staying here. There was a frantic scramble for clothes, but mine were in the barn. Fortunately, Katie's first priority was the filly. The guys went out to join her while I made myself decent. They coaxed Max back into the horse box, we said our goodbyes and they drove away. I never saw them again. The next day, I visited Heather in hospital to report mission accomplished. I managed to kept a straight face when I said that the people from the stud farm had performed well, but I could not stifle a loud horsey guffaw when she offered to pay for my services.
