Ryan laughed as he chased his sister, Taylor, into the woods. Her matching reddish brown hair flowed down to just her shoulder blades, over her white dress. She turned to look at him with reddish brown eyes, catching a glance with his before dashing off into the woods. "Taylor, you're not supposed to go in there!" he shouted, noticing she passed under the arch made of naturally bent tree branches and vines. Running after her, he immediately felt strange as soon as the soles of his sneakers past the arch. Gasping, he felt a lot lighter than he was, like he would soon simply float away. "Taylor..." Gazing at his sister which was a short distance away, he saw the wind blow up her dress. His face blush around the small freckles on his cheek as he saw his seventeen year old sister's teenaged slit. Strangely the sky slowly started to turn a fiery orange as he ran towards her, adjusting the bulge in his tight blue shorts when she looked away.

Finally catching up to her, felt like he should have scolded her for running past at the arch, but he couldn't say anything as her back was turned to him. As she turned her head to gaze at him out of the corner of her eyes, she slowly lowered herself to her knees, inhaling the smell of the patches of flowers that dotted the area. Heart pounding in his chest, Ryan watched as a flesh nub pushed up his sister's dress, flicking left and right as a light brown colored fur sprouted along it until a reddish brown tassel formed at the tip. He saw his sister's tight looking slit slowly turn a darker shade, almost a grayish black as the skin thickened. Tempted by her change, he roughly grabbed hold of the base of her new tail, bringing his flaring nostrils close to her leathery folds, inhaling her rich scent.

Taylor gasped with excitement, soon feeling Ryan's thickening rough tongue lapping at her virgin sex. He pulled back, gazing at the slobbery mess he had left with a big smile on his face, showing off his shifting, blocky teeth, giving off a light breigh, "Ee aw...." The leather gray and black soon spread to the tight little pucker between her smooth, rounded ass cheeks. Cocking his head, he leaned forward and gave it attention as well, lusciously lapping at it. Taylor bit her lip, moaning as she felt him wet her tight little hole. Her fingertips writhed in the grass in front of her, turning a dark shade before hardening into polished hooves. She grew extremely excited, moaning as she dripped between her legs, pulling off her dress to eagerly rub at her sensitive nipples on her firm breasts.

Just as Ryan heard a slurping in his ears, Taylor turned around and pushed on his chest, grunting when he hit the ground, his shorts easily ripping as his ankles went over his head. A look of shock on his face a dark brown furred tail flicked on the ground as his massive girth of a cock bobbed between his legs. As Taylor leaped on him, he moaned, she grabbing the back of his thighs, burying her tongue into his tight pucker. He breighed again, throwing his head back, licking his lips as they became dark and thick, a dark brown fur sprouting across his face, "ReeHAW!" Reaching up, he fondled his ears as they became nearly a foot long, stroking across the smooth brown fur that sprouted on them. He watched as Taylor rimmed his asshole, seeing her lips turn dark, her face stretching away from her skull as her ears reached far over her head; more of that light brown fur sprouted across her face, a dark ring forming over the new snout which appeared over her lips.

Ryan curled his toes, feeling her tongue darting in and out of the ring of his tight pucker. Soon, he couldn't curl them anymore, gasping as they cracked, the skin around them melting together as they shifted into a single boney structure before fading into a marble black. He grunted when Taylor stumbled forward, falling onto him. She looked back as he did, seeing her ankles pull away from her already hardening toes. They writhed and grinded against each other, feeling their bodies change, more fur sprouting along every bit of flesh.

"HEEAW! HEEAW!" she breighed, feeling his cock thickening as it grinded against her leather slit. He grabbed hold of her, thrusting his cock back and forth over her folds as he lustfully suckled at her right nipple, roughly fondling her other firm breast. She started to breath deep, feeling his mushroom cockhead suddenly flare, the flesh becoming thicker, harder. Taylor gasped when she felt it dip in and then out of her folds until...

Taylor breighed uncontrollably as she felt Ryan's leathery cock plunge deep into her wet cunt. Gasping as she turned around on his length, Ryan joined in her chorus, his jaw hanging open as he thrust into her wet folds, roughly fucking her like the animal he was turning into. Clenching his eyes, he felt his swelling sac swing each time he thrust hard and fast, actually swinging forward and smacking her in the stomach. He found an all new pleasure in the light ping of pain as they hit hard. She arched her back, feeling him bite into her thickening neck, hearing his jaw cracking, his nostrils flaring with breath as they pulled away from his face, forming a short snout when they finally met.

The half human jenny clenched her swelling reddish brown eyes as he roughly tugged at her tail, reaching around to roughly tweak at her breasts with his shifting hoof fingertips. He wasn't fucking her like a human or his sister anymore, he was mating her, bucking into her as if life its self depended on it. She gasped when he felt him tightly wrap his arms around her waist, tightly pulling her. Hearing him grunting over her shoulder, she raised her head and called out when he slammed into her depths over and over again, "EEEEAW! EEEEAW!" She breighed in a high pitched female tone, feeling her tight folds wrapping around his girth, all the way to the sheath forming at its base, her insides becoming slick around his meaty cock as she came.

Ryan grunted and breighed, slamming into his sister until she moaned and gasped with her eyes shut in orgasm. He turned his head, nuzzling his large, powerful jaw along her back, running his reddish brown mane along her light brown fur as he thrust a few more times. Giving off a whimpering breigh, there was a loud slurp as he pulled out and then thrust back in one more time, giving off one proud, "REEEHAW!" Covered in sweat, Ryan leaned over Taylor, supporting himself on all fours as his large sac churned, pumping her with copious amounts of cum. She panted and moaned, feeling both of them dripping between her legs, spilling his seed all over the ground.

When he felt he was finally done, Ryan pulled out, breighing proudly as impressive amounts of cum flowed past his cock head. Taylor joined him, breighing as the amazing pressure left her insides. Almost naturally, the scent of food nearby enticed the hungry ass and jenny. They grazed on the grass and the bushes of berries nearby, staining their fur with the red and blue insides of the berries. But only after an hour of grazing, Taylor grunted and breighed, feeling her brother's weight on her back again, his stained hands groping at her full stomach and her breasts. His virility had increased tenfold and he was ready to mate with her again...

After a very long time had passed, Taylor opened her eyes, looking up at the starry sky, gazing at her human hand which was a very rare sight. Hearing an agitated grunt behind her, she looked over her shoulder, feeling Ryan's swollen cock grinding between her ass cheeks as he slept. She watched as his snout slowly shrunk back into his human face, even reaching out to stroke his plump lips as they turned pink again. She realized he was caught in an ongoing need for sex, and so was she. Even when they searched for the way out of the place they had found, they had to fight the raw animal urges they were cursed with. But during times like these, Taylor would turn towards her brother and lovingly cling to him, even as her solid belly started to swell...

End.
