All right everyone, it's time for a new collaborative story thread! This one is for you animal lovers out there, winkwink nudgenudge...

Let's start out with an ordinary farm at first, with your usual animals. Pigs, goats, sheep, cows, horses, and so on. Then we can expand to more exotic animals as the ranch expands, such as retired zoo and circus animals like camels, bears, rhinos, hippos and even elephants. Perhaps our heroine and/or hero can take a vacation at the seaside and explore the possibilities there as well...

Oh, and did I mention I threw in some incest too?

It's all up to you! And me, when I have time. Hehe.

The Haymore twins, Lori and Lyle, had always been closer than their parents (or anyone else) approved of. So when they had the chance to move out and get a place of their own, they jumped at the chance.

"It's perfect," said Lyle. Lori merely grinned at the real estate agent and nodded.

"All right then, Mr. and Mrs. Haymore," said the agent, thinking the fraternal siblings were a married couple, "let's go back to the office and sign the paperwork."

Three weeks later, they attended the local monthly stock auction and then returned home with their first new acquisitions. The twins helped each other poke and prod the animals into their pens and pastures, then went inside to have a romantic evening in bed together, as they did most nights.

Next?

(Just to be sure we're all on the same page, Lyle is male, Lori is female, and fraternal twins are not the same as identical twins. They are formed when two eggs are impregnated at the same time and share a womb, and so can be different genders and look as different from each other as any other siblings.)

"Yeah, well, does it taste like pussy too?" Lori strode over to her brother with purpose, then dropped to her knees and took his cock deep into her mouth, suckling and tasting. Lyle spasmed, his knees almost folding up instantly. She slurped her way back off noisily, then looked him in the eye, swallowed, and licked her lips.

"Wh.... well...?" he asked shakily.

"Close enough," she sneered. All he could do was watch with his overalls down around his ankles as Lori climbed into the pig pen and stripped completely naked.

There was an element of danger since, as legend would have it, full-grown swine have been known to kill and eat people, but that was more than fine with Lori. In fact, a little bit of danger got her off even more.

"C'mon pigpigpig," she called from her position on all fours, ass pointed toward the enormous boar. The sound of her hand slapping her ass made him curious, and he snuffled at her fragrant parts with his flat, wet snout. Lori moaned and spread her asscheeks, face dipping down into the fresh wood shavings in the bottom of the pen.

She did not get what she had been expecting, however. The boar shifted forward and Lori squealed as his distinctive corkscrew-shaped cock slid deep into her ass. She was no stranger to anal, but the action caught her completely off guard, and she found herself sprawling forward under the force of the massive creature having its way with her anus. It was all she could do to keep herself from being shoved into the fencing. Somehow one of her hands found her clit and began to rub, as the strange shape inside her hole reamed it back and forth relentlessly, the curly tip of the eighteen-inch rod well past her sigmoid bend.

"Oh GOD!" she screamed, and came hard as the animal released its load deep inside her colon. Lori whimpered as the entire length was pulled out roughly from her spasming asshole. The pig was done with her, but she wanted more.

It'll be nice to see some male/animal bestiality for a change, it seems like all there ever is is Female/animal.

That being said, I would love to see Lori get fucked by a horse

That would be quite sexy. Make sure the stallion is actually fucking the girl hard as if she was another horse, that's be sexy, some nice stretching/bulging from the horse cock would be sexy.

Milking those balls to be sure Lyle gets an extra big load?

Horse semen enema. Sounds good to me.

... it's like all of you are reading my mind ... my brain is spinning on this one ... and I'm picturing a big open area in a barn ...

 ...the sweet smell of hay wafting through the air, tiny motes of dust floating through the splatters of sunlight streaming through cracks of the weathered barn board.  Up above, running across the high ceiling are a series of massive hewn beams, and hanging from center one is a huge winch assembly, suspended by a large heavy chain.  To the left, the nearest sidewall is speckled with large wooden pegs and big rusted iron spikes.  Hanging from every one of these hooks is an assortment of ropes, chains, bits, bridles, various leather items, and leather straps, some with huge buckles – there was more leather than one could ever imagine - enough to make the local Tack Shop look like a small checkout counter at a tiny Mini-Mart!  Amongst the treasure trove, hanging all by itself was a large well-used, worn leather whip, the leather-wrapped handle sweat-stained and faded.  At the very end of the eight foot long braided rope, a topknot, ending with a cluster of twelve inch thin leather straps ...  on the other wall, directly across the room, hung a large leather apparatus of sorts ... which on closer inspection revealed that it was a leather sling device ... and one of a very sexual nature ... sturdy and very well constructed ... consisting of a huge metal hook attached to six thick chains ... that ... when suspended ... became an extremely versatile cradle ... one … that once … a body was in ... and restrained ... the possibilities ... were ... endless.

The unlikely pair; brother and sister as they were, touched and inspected every item there was, fully enthralled with what they could do with all the items.

Lyle and Lori, so turned on by their latest discovery, which was made more than obvious by the massive erection protruding from the waistband of his jeans, and the huge wet splotch in the front of her tiny shorts, ripped off their clothes, and fucked each other silly, right then and there, on a pile of hay bales.

Completely lost in the throes of passion with each other, while having the most amazing, sweaty, body slapping action one could have only seen on Pay-4-Porn, their imaginations running wild with the thoughts of their new-found items, they fucked harder than they had for the longest time.

However, during the voracity of their most intense mutual orgasms ... ever ... they missed the one thing right in front of them ... a single grey eye ... watching them ... through a knothole ... in the siding of the barn … the eye being that of ... the real estate agent ...

Soft whines and scratches could be heard through the large barn's back door, Lori and Lyle groaned in unison the brother untangling his legs and stepping away from his still horny sister, cum and sexual lubricant connecting their crotches with thick strands, Lyle groans as he stretches his legs and walks to the back door.

The moment the older brother opened the wooden hatch he was assaulted by the two dogs they owned, eager tongues lapping away at the combined juices on his crotch wide tongues pressing against one another and his sensitive head. The two Border collies wagging their tails (And most of their posteriors) As they lavished their master with attention and love.

He groaned out at his pet's enthusiasm shivering as the female of the pair starts digging under his balls. Her snout lifting up his balls before snuffling his taint.

"Easy there. Plenty to go around. Hey Doug, go ahead and treat Lori for a bit."

The dog barked and wagged his tail before bounding across the room diving his muzzle before lapping away at her moist pussy lips,  Doug's wide tongue delves into her pussy curling around and licking at her G-spot.  Her legs splay laying her head back and moaning as her pussy is pleasured and invaded. 

Lyle walked slowly back to the hay bed the female collie hot on his heels. "Alright, alright Sheila I'll be right with ya." Lyle pat his canine lover on her side, the cute dog lying on her down without a moment's hesitation tongue hanging out of her muzzle and tail wagging happily. She spread her legs, revealing the black triangle of her pussy. He dove right between her legs, licking and lapping at her tight mound in a mirror of his sister. 4 lovers, 4 mates, two pairs of brother and sisters.

After a full minute of lapping at their ladies Lyle and Doug stop assaulting the women's pussies, each straddling the lady under them before slipping their cocks into the tight wet embrace. Doug hammering into Lori's twat, while Lyle took a more gentle approach on Sheila.

( I would make it bigger, but I'm tired right now. I'll add more to it later (or let someone pick up where I left off.)

Even if they are fraternal twins, one has to be born before the other, the age difference is just a couple minutes. I figure that the brother is born first, but the sister is the one who is more adventurous. I don't know why that speaks to me.
