Chapter 5: Belle's first heat

If Belle had grown up as a normal human female she would have understood what was happening to her because of her menstrual cycles and what fertility really meant, instead her equine oestrus cycle was her heat period.

Her first heat went unnoticed by Frank and only lasted three days. However, her second heat eighteen days later was more intense because she had been frolicking around with the young colt and his pheromones were a turn on for her as were hers for him. She didn't understand the colts interested in her.

Frank watched them closely as the colt smelt her sex and manoeuvred her into a corner of the yard. He knew that she would let the colt mount her, and mate with her when she was ready. The possibility of pregnancy was minimal because of his age. Frank was also aware of the fact that the Omnibach brothers wanted a human male to try to impregnate her and Frank Omnibach had already given his consent to Frank Mullins.

Day 1 of her heat,

She was flashing her winking vulva at the colt, as he followed her around with his semi erect cock swinging below his belly. Every time Belle stopped, the colt attempted to mount her. With Belle, walking on two legs and standing upright the colt was unable to mount her successfully. The colt's persistence was only bringing minimal rewards, every time he reared Belle moved away from him.

Frank knew that it was only a matter of time before she would stand for the colt.

Before Frank could get to Belle, she walked into the breeding shed and into her stall into her stall closely followed by the colt. She remembered her training on how to use the platform bed for support. Using the platform, she closed her hands into fists she leaned forward and supported her upper body. Bending forward she assumed the position for mating, with her feet spread and her back slightly arched, her vulva was slightly open showing deep red inside instead of the normal pink.

The colt exhibited a flehmen response by raising his head and curling his upper lip tasting her scents by drawing them into his vomeronasal organ. He was testing her readiness to breed by. Her aroma was overwhelmingly strong and he couldn't help but move his nose to her tail. As she felt his hot breath on her buttocks, she raised her tail. She looked back as the colt mounted her and clamped his forelegs tightly around her waist as he thrust his cock at her desperately trying to locate her winking vulva. As the head of his cock found her opening, he thrust all of his cock into her. Several strokes later, the colt stopped with his cock still deep inside Belle's cunt. Every time he twitched his tail, he ejaculated cum into her. Once he had fini9shed and dismounted Frank led him out of the stall and locked him into his own stall after locking Belle in hers.

He rang the vet John Omnibach, who in turn notified Susan Mixon that Belle been mated for the first time.

When John and Susan arrived, Frank thought he would be in trouble, instead, John said, "The best times for you to breed with her is on the second day of her heat cycle and then breed her every other day until she goes out of heat. She has to have live sperm in her genital tract when her ovary releases her egg. This should be late on day six."

"Ok John," Frank replied.

"Have you ever tried any sexual activity with her?" John asked.

"No I haven't, but I guess there's always a first time." Frank replied.

"Well Frank," John said. "Its all up to you now, Enjoy your self tomorrow."

Day 2, 9:30 AM.

By the time John Omnibach and Susan Mixon arrived, Frank was already naked and standing alongside Belle, rubbing and massaging her back just above her tail with one hand and pinching her buttocks between his thumb and forefinger with the other. She had her tail raised and to one side leaving her winking vulva in full view.

With his back to them, Frank heard John say, "She seems happy to let you touch and fondle her doesn't she?"

"Yes she does now," Frank replied.

John Omnibach watched as Belle's winking pussy exuded several squirts of sticky mucus like lubrication. He knew that Belle was ready to accept Frank's advances.

As the naked Frank turned toward John and Susan, she clasped her hand over her mouth stifling a gasp as she saw Frank's thick erect cock and large balls for the first time. She also noticed what appeared to be a sort of admiration in Belle's eyes as Frank moved behind her, gripped her hips in his powerful hands, and moved closer to her buttocks until his cock was nestled between her buttock cheeks. Belle wriggled and squirmed trying desperately to position herself for Frank's cock.

Frank pulled back and flexed his cock as he searched for her slime-covered opening. Belle leaned further forward as the head of his cock touched her winking cunt, in contrast to where the stallion had shoved all of his cock into her with a savage forward and upward stroke thus forcing his cock all the way into her tight virgin cunt. Frank on the other hand slowly pushed his cock into her, trying not to hurt her. Once all of his cock was inside her, he waited for her cunt to become accustomed to his size. Several seconds later, he started pumping his cocks lowly in and out of her clutching pussy. Having had sex with a mare on numerous occasions, he knew how to control his lovemaking so that whoever or whatever he was making love to would get as much enjoyment out of it as he did.
