Bending down Mistress Deb picked up a jar of oil and proceeded to smear a liberal amount between the thighs of Farm Slut's bound and spread legs.
Farm Slut felt the oiled hand of her mistress as it rubbed around inside her thighs. Quickly the memory of service to the dog flooded back from her brain as she tried with all her effort to move further onto the dildo in her ass. She kept straining against her bindings and tightening her bowels around the shaft inside her, long after Mistress Deb had stopped applying the oil.
Farm Slut froze inside her coffin when she heard the unmistakable sound of a horse's hooves approaching her from behind her. They stopped, and Farm Slut listened for what she feared was about to come.
The horse had been attended to by Cathy and Janet to prepare him for being serviced by Farm Slut. He was led out of his stall, to the back of The Trojan, that looked very much like the beck end of a mare.
The platform that held the narrow coffin shape had been specially built to accommodated the mating of a horse and woman. The top of the coffin lid was rounded and padded for the horse. At each side of the raised coffin, was a ramp allowing the horse to step forward and up, putting the horse in a more natural mating position. In this position the horse could use his massive strength to power his cock deeply into its intended vessel.
Deb now led the horse up and over the small coffin shape as the stallion walked up the ramp on each side of the platform. The horse's cock bobbed up and down, as it placed one hoof in front of the other until the thick hose slapped up between Farm Slut's spread legs.
Farm Slut jumped in her restraints when she felt the gigantic member slap against her spread cunt. She closed her eyes tight, and tried to imagine the size of the thick tube shape now moving between her legs. She could feel it up against her spread cunt lips as well as a good 3-inches down the inside of her thighs.
She thought about how she had wanted at first to service the dog inside her cunt. She remembered how relieved she had felt, when Mistress Deb had decided she should use her ass. Farm Slut knew that her cunt had never taken anything larger than two fingers. She couldn't imagine what it would feel like to have a real size cock using her cunt, let alone one as monstrous as was now rubbing itself between her legs.
She felt the elephant sized cock pull back from between her thighs and press hard between her held open cunt lips. She gritted her teeth and squeezed her eyes shut for what was to come next. She felt the pressure against her cunt opening. "It's not going to fit!" she thought when she felt huge diameter of the cock end pressed against her backside. She felt the outer skin of her cunt being forced into her spreading cunt hole as the horse increased his pressure and took a small step forward, then it happened!
Farm Slut heard the echo of her screams rebound off the walls of her tight wooden surroundings, as the horse's thick hard cock forced its way into her tiny cunt. Before Farm Slut could get use to the thickness, the stallion took a another small step forward and embedded another 4-inches of the thick shaft inside the tortured confines of Farm Slut's tight hole.
Farm Slut opened her mouth to scream, but not a sound emerged from her throat. She felt the mammoth sized cock pushing against the far wall of her cunt chamber, demanding entrance through her virgin cervix. The force against her cervix was enormous. Bound and helpless, she felt her cervix opening, spreading itself to allow the stallion's cock entrance into her innermost secret chamber.
The stallion took another step up the ramp. The pressure against Farm Slut's cervix increased to the point she thought the horse's cock would burst through taking her partially closed cervix with it. Under enormous thrust, Farm Slut's cervix opened, and the stallion's huge pipe to squeezed through, ramming itself all the way forward.
The stallion was almost fully embedded. Only 6-inches remained outside Farm Slut's tremendously stretched open cunt. The stallion now hunched his hind quarters and drove the remaining length of his shaft inside the tortured hole. Now he was ready to be serviced by Farm Slut.
Farm Slut felt the immense shaft pull back out of her inner womb. Almost immediately her cervix started to close as the shaft exited the rim. With a irresistible force, the thick shaft drove back in, punching through the partially closed cervix, and rammed through to bounce against the wombs far end.
With each drive of the horse's thick cock, Farm Slut's outer cunt lips were sucked inside along with the animal's huge cock. The stallion drove in and out with long, steady, unrelenting strokes. With each 18-inch stroke Farm Slut could feel the pain give way to more and more pleasure. Her entire inner body was being stroked by this mammoth creature's cock. She couldn't believe the length of the stallion's fucking tool as it slid in and out of her. Now, every inch of its glide felt like ecstasy.
The words shot from her mouth, unrealized, and spread through the barn, muffled by her tight enclosure. "OH, YES! FUCK ME! FUCK ME HARD!" Every one in the barn turned to watch the hind end of the gigantic horse plowing into the back end of The Trojan as its occupant shouted for the creature to fuck harder and faster.
Farm Slut was going wild inside the box that held her tight, as the 18-inch thick cock continued to slam in and out. Farm Slut could feel the horse's heavy balls slap her lower stomach as they curled around underneath and between her spread legs. The shear length of each stroke was beyond elation. It was pure euphoria to Farm Slut. But nothing could prepare her for what was about to happen.
Suddenly the horse reared on his hind legs. His cock drove inward, its entire length. The head flared as it spewed gallons of sperm into the already filled chamber of Farm Slut.
She felt the trembling massively thick horse's cock throb, then tremble, then ram up inside her fully, just as the fiery hot liquid shot into her inner womb and filled her like a balloon. She felt the chamber behind her cervix expand. Her cervix was stretched so tightly around the thick cock. It couldn't escape even under the unusual pressure. Then as a second burst of sperm spewed forth from the horse's balls, the cervix was force wide, jetting the compressed sperm into her cunt chamber to fill that up completely. The third spurt poured out of her body and bubbled around the horse's cock and her tightly stretched cunt opening.
Farm Slut never noticed the next pulses of sperm that flooded from her cunt and ran down her inner thighs in great globs of white streams. She was cumming. Every muscle in her body tensed and tightened, threatening to tear her apart. She was beyond control as the first wave of orgasm hit her cunt as spread through her thighs. Wave after wave resounded through her bound form, as she spasmed around the horse's giant shaft. Her body seemed to be on fire, fueled by the burning liquid, filling every crevice and fold. As the first eternal orgasm receded, another started, spread from her loans, and crashed through her form. It racked back and forth inside her, twisting and turning, until it every fraction of her body, felt the extreme pleasure her delirious cunt had received.
The stallion stayed fully imbedded in Farm Slut until every ounce of sperm had been deposited inside her, by his still pulsing member. When he did withdraw, it was amazing to watch. With one glorious leap to the side. His powerful cock ripped from the slut with a loud, "Thawup," pulling great globs of stringy sperm out of the gaping hole with it.
Farm Slut's cunt still spasmed after the giant horse had pulled himself out of her used orifice. She could still feel it opening and closing around the thick cock that was no longer there. Tiny tremors still rolled through her body from the powerful double orgasm.
To Farm Slut, this was pleasure beyond anything she had ever considered possible. This was her place in life, and she loved it. Sore, and tired beyond exhaustion, she found herself wondering when she could service the next cock. Then the lid to the box opened. She was taken from the box and helped to one of the stalls. She was set down on the hay, under the stallion that had just fucked her to rapture. She lay there, looking up at the deflating cock as it bent down almost touching her face, and stared with amazement.
