Several months after being fucked by her beloved unicorn, Horny, for the first of many times, Deidre received a letter from her older sister. Julia wrote that she had given up on men and asked if she could come and stay for an indefinite period of time. The two sisters had always been extremely close, so Deidre wrote back saying she would be delighted to have Julia come and live with her, for as long as she wanted. One thing she was looking forward to was showing off the exploits of Horny, who had been a better sex partner than any man Deidre had ever known.
Her desire went beyond ordinary bragging, all the way to sibling rivalry. Julia had always been the wilder of the two, with her younger sister rather overshadowed by what she had done. Whatever Deidre did, Julia was unimpressed, because she had been there, done that, and probably many times. However, it was almost a certainty that she had never had sex with a unicorn because, according to her letters, she had never owned one, and rarely traveled in places where they would be common. In the process of giving Julia and herself a good time, Deidre hoped to finally do something to impress her.
On the prearranged day, Deidre drove to the train depot to pick up her sister. They hugged and kissed in the normal way and loaded Julia's luggage into the station wagon. Most of it was piled in the back, but one suitcase remained on its owners lap, with Julia's hands resting protectively on it. When they arrived at Deidre's home, that suitcase was the first to be taken out, and Julia carried it directly to the comfortable room where she would be staying, and set it on top of the bureau. None of her other possessions were treated nearly as carefully.
After dinner, the two sisters talked for hours, catching up on news and gossip of friends and family, and what each other had been doing since they had last gotten together. It was late when Julia opened the suitcase that had rated such careful handling. Inside were a large tube of Aquaglide and a collection of dildos and vibrators of all shapes and sizes. Deidre looked at it, feigning boredom. "Not bad," she said, ostentatiously stifling a yawn.
"Not bad?" Is that all you can say for this stuff?" Julia brandished a three-speed, extra large, double-pronged oscillating Jackrabbit with outsized pyramidal beads and a concave swiveling clit spur. "Do you realize what this thing can do for your ass and your pussy?" she demanded of her sister. "And both at the same time, too."
"Well, I guess I can see where it might be kind of fun. If you didn't have anything better, that is."
"Do you have anything better? Can I see it? Can I use it?"
"Yes, but not tonight. You can see it and try it out tomorrow. But just so you'll get the most benefit from it, don't use any of these tonight," she advised her sister, pointing at the collection of toys.
Shortly afterward, the two women went to their separate beds. They met for breakfast in the morning, but Julia hadn't slept as well as she wished. All night, she had been wondering what could be better than her custom-made jackrabbit, which was the envy of all her unattached female friends, as well as most of those who were married. After breakfast, Deidre went to a bin in the kitchen, took out a handful of stale doughnuts and put them into a basket. She added fruit and a bottle of olive oil before taking the basket to the shed behind the stable, where she tossed in a forkful of the top quality hay she always bought for her pampered unicorn.
Julia was aware, of course, that her sister had a pet unicorn. Several letters had made mention of the strong affection between the two. However, she thought that feeding him fruit and doughnuts might be overdoing the kind mistress act.
"What are the doughnuts for?" she asked Deidre.
"They're for Horny. He'll need his energy today."
The reference to "energy", the unicorn's name, the olive oil, and their discussion of the previous night suddenly all became connected in Julia's mind. She thought she might know what the treat was that Deidre had for her, and fervently hoped her guess was right. However, she wanted to make sure.
"Why did you name him 'Horny'?" she asked.
"Because of the horn on his forehead, of course."
"Any other reason?"
"You'll see." Deidre's cryptic answer, combined with her lewd and sly smile confirmed Julia's best suspicions.
Julia grabbed her sister by the arm to hasten their walk to the stable. "I think I'd really love to make the acquaintance of His Horniness." She carried her purse, because there was something in there that she might want to use if her guess was correct.
The stable had a well-scrubbed wooden floor and fresh straw, because it wasn't only in his diet that the unicorn was pampered. He smelled the fruit and doughnuts and greeted his mistress effusively. Unicorns are quite intelligent, and Horny knew from experience that the sweets would be delicious and that he would experience a really good time immediately after eating. Deidre closed and locked the stable door, turned on the light and closed the shutters for privacy. It was unlikely anybody would disturb them, but she wanted to take no chances.
After placing the olive oil in the rear of Horny's stall, Deidre set the basket on the floor in front of him and smiled at the way her sister stared in fascination. Julia watched as his long, thick tongue thrust under the hay, curled through the hole of a doughnut and lifted it up to his mouth. Thinking avidly of what that prehensile tongue could do for her, Julia's pussy started twitching, and a few drops of her juices trickled out and down her legs.
"Horny seems to be quite talented. What else does he do?"
Deidre smiled at her sister's eagerness, and went to get the polished wooden bench she kept in the stable for times like these. Setting it down on the spot where she knew optimum pleasure would be obtained, Deidre instructed her sister to remove her clothing and lie on her back, legs straddling the bench and her feet on the floor, so she could find out. Julia was glad to see her expectations were going to be at least partially fulfilled, and complied happily.
Horny saw the woman lying on her back and remembered the delicious treat that his mistress made available to him when she did the same thing. He stepped closer, and his sensitive nose detected an aroma much like that of the treat he remembered. Further investigation showed that the new aroma came from between the strange woman's legs, the same place as the familiar smell came from on his mistress's body. Cautiously, he extended his tongue and licked. The taste was not quite the same, but it was just as good, and his tongue quickly sluiced up all the flavorsome juices.
"Oh!" Julia blurted, at the touch of the unicorn's tongue on her crotch and the insides of her thighs. "Oh! Oh, my God, that feels good!" She spread her legs farther apart and moved slightly closer, wanting Horny to continue what he had started.
As is the case with any equine, a unicorn's tongue is covered with thousands of tiny papillae, which act as taste buds and also help convey food and water to its mouth. To Julia, those tiny bumps were warm and alive and moving, and felt wonderful when they massaged her crotch and pussy lips and the other sensitive parts they touched. They were vastly better than the molded bumps on any of her toys, or anything else she had ever felt. She sighed and moaned and whimpered from the exquisite pleasure, and fucked her pussy up against the source of it. She didn't know it yet, but it would get much better.
Besides her sounds and movements, Julia's rapidly growing pleasure was demonstrated by the plentiful juices she was producing, and that was what Horny wanted. After licking everything off the outside of her body, his tongue went to the source, burrowing into the soft hole that was secreting the delicious droplets. The thick organ squeezed into Julia, stretching her pussy like a huge cock, the ultra flexible tip caressing her g-spot and all her other highly sensitive places. She went berserk from some of the best sexing she had ever gotten. Her body rocked from side to side and back and forth and thrashed all over the bench, while she let everybody within earshot know just how wonderful it was. Horny ignored her movements, his tongue just burrowing in deeper, while its tip flicked about in search of more of the delicious juices.
