Tori woke her in stall, the heifer across the hall mooing in greeting. Giving a nod, the alpha female returned the greeting as the pair stretched the soreness out of their muscles. Down the hall Tori heard others also coming awake.
Ten minutes after most of the heifers were awake a loud buzzer sounded and the stalls opened, letting them wander out of their beds. The farm had become more mechanized, giving the handlers a chance to focus on work that helped the livestock live comfortably rather than just babysitting them.
All of the heifers but Ka were pregnant, some far along that even on all fours they waddled. Tori was just into her fifth month, but starting to show. The heifer not with child roamed the field watching the pregnant ones warily. She knew she didn't fit in with them, and as they gathered together made her feel more out of place.
The gate to the bull barn opened and the heifers squealed at the thought of seeing the main bull on the farm. It was due to him, and his breeding that lead to the improvements on the farm. Not only from the sale of his calves, but he had left the farm to breed his line into other farm's heifers.
A disappointed groan washed over the field as Tomo, the secondary bull, emerged from the newly opened barn. While the bull's cock was nearly as impressive as the primary bull, the secondary didn't have the command of the heifers as Mika.
Seeing Ka aside in the field, Tomo headed toward her. With Mika not available, it was up to him to impregnate the remaining female. Ka saw the male heading toward her and she circled back to the herd, hoping that the expecting mothers would protect her. The females accepted the breeding female into the middle of the herd, shielding her from the male which caused him to moo angrily.
The herd responded and Tomo stomped a hoof, making a demand. The females looked to Tori, the alpha female for guidance. Tori responded to the male, waiting for his dominance. Scent wafted from the male's collar, enticing the female.
Finally Tori mooed a submissive response and Tomo sniffed her, nipping at her sensitive nipple and caused her to moan. Seeing the alpha female give in, the herd parted and revealed Ka. As Tomo walked toward the female hiding, the other heifers nuzzled him showing their deference.
Tomo made it to Ka, mooing his command for her to submit. The heifer turned, denying the bull's commands. Getting more insistent Tomo moved closer, letting the pheromones from his collar waft into her nose.
Shaking her head, Ka felt the special scent that caused her to crave a bull work its way into her system. Her cunt tingled and her head was filled with thoughts of servicing the bull who spoke to her. Another demand had her trembling as she mooed her acceptance and let the bull circle her.
The bull wasted no time mounting the heifer, getting a cry from the female new to breeding. A bull cock as nearly four times larger than a male, and since she refused he mounted her with no warm-up.
The herd moved away from the mating pair, each of the heifers mooing in desire after getting a whiff of the bull's collar. They gave the panting female who now only made mooing noises mixed in with the grunting of the bull, they crowded together for support.
Ka screamed as a climax washed over her both from the rough fucking and the fragrance from the bull. She shuddered but was given no reprieve from the bull who stayed buried in her, thrusting twice for every breath. He mooed a dominate moo, hearing the herd answer and Ka scream again in pleasure.
