6. The breeding device
Linda took her movable phone and called the house.
"Sean? Everything all right here. Mares were milked and are out on the fields. Kumbo got his ring and did not even notice it. I think we may proceed with the mating?"
"Great, Linda! I and James will be there in a minute."
Linda went to meet Dara. The centauress was pacing the stall; she was in full heat now, and her face showed clearly her anger at being locked. Linda smiled to her:
"Dara? Did you wash your face and bush your teeth?"
"Yes, miss!" said the girl.
"Good! Now have a surprise for you ... Let me see here!"
She went round the mare and lifted her tail. The labia were swollen and a bit wet; the ring was shaking rhythmically as her cunt opened and closed in an automatic, instinctive movement.
"You will receive a male today," said Linda. "You will be the first of our mares to give a foal. Aren't you happy?"
"Oh!" said the girl. "Kumbo was going to mate me as you appeared the other day!"
"Kumbo is busy with his work," said Sean's voice. He and James had arrived and were watching as Linda let Dara's tail fall again.
"Oh! But I want..." Dara began.
"Shhhh!" Sean's tone was cold and firm. "You will do as you are told, Dara ... Remember what we said the other day? You have to serve your master's needs ... And I think it will be better if Ximbo covers you."
He caressed Dara's face and noticed how puzzled she was. He smiled to her:
"You will be our first mother! I know you will be a good one, Dara. Now let's go!"
He clipped a leash to the girl's collar and tugged Dara to follow him. James had gone to fetch Ximbo; he greeted him and told him the great news. Ximbo was pleased to hear that he would mate, but he know that Dara was Kumbo's preferred female.
"But ... Kumbo wants her, Master James!"
"Oh, that... We think it is better if she goes with you," said James with a smile. "Never mind, Kumbo will understand. Now come!"
He led Ximbo to a stall that had been prepared for mating. They had put in it a sort of rectangle made from metal bars, which went from the ground and reached a height of about five feet. It was large enough to contain a mare, but she would not be able to turn around inside it; she would stand in it, facing the wall, her rear exposed to the male. A low door also made from metal bars and provided with hinges could be closed behind her; the interval between the upper bars could be adjusted to leave the cunt exposed. On the vertical bars of that door, some inches from ground, two straps of leather had been placed, to hold her hind legs open in the case she would resist penetration.
Dara had been brought to the device and was looking at it, with an expression of fear on her eyes.
"It's OK, dear ... This is how we mate cattle here," said Linda. Sean frowned at her: he did not want to hurt Dara's feelings. But the mare was not paying attention: she was looking at Sean, puzzled by the sight of the device.
"You go into there, dear ... This is how it is supposed to be." Sean patted her superb rump. Lifting her tail with his other hand, he caressed her pussy softly. "You want something here, don't you? Then go!"
Dara entered the mating cage and Sean locked the door behind her; then he kneeled and attached her ankles to the vertical bars, leaving the cunt free for the male. Then James came into the stall. As Ximbo's sniffed the scent of the mare's wet pussy, his cock stretched quickly and he tugged at the leash that went from his collar into James's hand. The biologist winked approvingly to Sean and Linda and let the leash drop on the ground.
"Now, Ximbo! We want you to make a fine colt in Dara ... There you go, boy!"
Ximbo emitted a long whine and put his front legs over Dara's rump. He held her shoulders firmly and began to lick the back of her neck, as his now stiff cock began to search for the mare's hole. She was eager to receive him; the three humans sat on the ground and watched what was going on.
Ximbo found the mare's pussy and with a swift thrust slid his cock inside it. Dara whined loud and cupped her beasts with her hands; now Ximbo's member had disappeared into her canal, and he was thrusting vigorously into her. His balls bounced as he moved his whole body, and a swishing noise could be heard as they hit the mares's soft rear. He could feel Dara's tight walls closing on his cock, as she moved back and forth to meet the male's body. Linda stood up and took a close look: the ring did not hinder the penetration. It was rubbing the upper part of the male's cock, adding, so it seemed, to his pleasure.
The embrace lasted for some minutes; the thrusts went on, faster and harder, as Ximbo leaned forward to touch Dara's tits with his hands. The girl was shaking with pleasure as she felt the caresses of one of her species; Ximbo gave one more powerful thrust and expelled his load in the warm, wet canal. Dara felt it and closed her eyes; her tongue was licking her own lips, as she felt the climax approaching – and then, with a jolt her whole body, she came too.
Ximbo kept sliding his cock in her for some moments, then he stopped. "Was it good, boy?" asked James.
"Oh, yes!" gasped the centaur.
"You should say 'Yes, master', or you will never have another mare here," said Sean severely.
"Yes, master," said Ximbo, trying to catch his breath.
