Soft auburn hair tickled Jamie's nose. Face buried in his sister's crown, Jamie drank in her scent. She smelled earthy, and sweet; like cream. She was short, curvy and soft. Jamie's black nipples pressing into Jess's pillowy back, rough reddish-brown fur rubbing the chest between them as Jamie's arms pumped with motion. Jamie's hands worked furiously on her long, rubbery teats, squeezing and pulling in a repeating rhythmic motion. Each tug producing a thin stream of white creamy fluid, shooting out and pattering over the floor and the kneeling form of Henry, the twin's father, as he busily suckled on Jess's udder. Between tugs, beads of milk dribbled out and over Jamie's clenched hands, warm and wet, slightly sticky and sweet smelling. His sister was a bag of milk right now. Moaning and mooing in delighted release.
The sound of her relief excited Jamie. There was nothing to get blood flowing like hearing someone else having a good time. Jamie's horsecock was still half-turgid and sopping wet from the unfinished fucking she'd given Melissa. She might have felt more like a woman, or mare now, but having your cock sqashed between you and the soft, full ass-cheeks of your sister was enough to stimulate even Jamie. She thrust her hips, feeling the hardening shaft sink into the soft mushy flesh of Jess's cleft, fur and curling tail enveloping it as it sank. the flat head poked out the top and pressed into Jamie's own navel. Blood flowed and she buried her face in the neck of her sister.
"God you're so soft..." Jamie moaned. Thrusting again and again, rubbing her hardening shaft between the volumious cheeks. With another thrust she felt the head of her cock press against the underside of her own tits, and sighed happily. Soft lips tickled Jess's nape again as Jamie leaned down to lick his sister. Jess moaned happily, grabbing Henry's head and pressing him harder into her udder, while simultaneously leaning back into Jamie, enjoying the embrace from behind by the amazon horsegirl.
"And you're so strong... " Jess moaned, feeling Jamie's arms wrapping around her, pumping away at her teats. Jess was jealous, she could barely heft all her tit flesh around, so full was it, and so small was her build. Jamie made carrying sizeable tits look easy, all toned muscle and gorgeous curves. If only she was that strong; she wouldn't struggle so much to get around. Though, to be fair, having her udder and tits sucked dry might lighten the load somewhat. She queezed her father's face harder into her udder. She could feel his moans vibrating through the mammary bag hanging under her belly, shooting straight to her core. God she wanted him. With one hand she began stroking and pulling at his curly brown hair.
Henry leaned into his daughter's touch as he felt her hands playing through his hair. Though his world-view at the moment was completely made up of warm udder-flesh and the sweet taste of milk, he still pictured his mate in all her glory in his mind.
Only, she was changed. A bit.
As in more furred.
With horns, cow ears and a short muzzle. Auburn fur covering her body.
He was rock hard imagining her like this. Pre-cum beginning to bead from the tip of his cock. Oh how he wanted to sink into his little girl. Shifting his legs, he scooted his ass under Jess, so that his bull cock stook proudly, and prodded Jess's udder from underneath. Smearing it's underside with slick pre-cum. He began feeling a pressure in his temples, a pressure in his head. It made him want to rut, to clash into something. He pushed his face harder into Jess's udder, almost knocking her off her dainty feet. She caught herself only because of Jamie holding her up. Behind Jess, Jamie was grinding up and down, it felt like a warm arm stroking her fur, rubbing it in just the right way. She shiverred at the feel of it, stroking against the grain of her fur. She felt so good, so sexy squashed between these two beastly cocks. So horny.
"Oh Daddy, so rough..." She happily wheezed, still running her hands through his hair. As she did her fingers came in contact with two hard bumps. It didn't take a genius to realise that they were the beginning of horns. Jess imagined her Dad with a big set of curved horns, and laughed. "Everyone's horny here." She giggled.`As she shook, her fat, swollen, slick cow lips rubbed off each other in exquisite agony. She needed something in it, quickly. She grabbed Henry's head and tried to pry it off her Udder. He held firm, however, refusing to let go of his meal.
"Daddy please!" She whined, uselessly pushing against him. Too strong, and too out of it, Henry snorted, grunted and kept suckling.
Again she tried pushing, but to not avail. She pushed and pushed, every time Henry wriggling and easily pushing back into her udder to suckle.
"C'mon sis. Push!" Jamie whispered in her ear and licked it slowly. Jess whimpered at first. Her arms burned from the strain, and she was only being held from falling back against Henry's onslaught by Jamie holding her up. Then. Something clicked.
That was it...
She was sick of feeling small and weak. Barely being able to hold herself up. Dainty fingers wrapped around Henry's growing horns and she grabbed on tight. Then she pushed.
Jamie felt her sister's arms ripple as she continued to reach around her, pumping her breasts. Something was different. She felt, as moment by moment, the pressure she had to keep to stop Jess from falling back lessened and lessened, and... was Jess getting taller?
A surge of control, of power built in Jess. She could feel her thighs thickening, chording up, calves straining. Then her stomach, her core and back, like steel rope snaking up her body. She felt powerful now. She planted her feet, toes curling as they gripped the hardwood floor.
Her back and shoulders were next, the pulling weight of her humongous tits and udder lessening. She stood up straigher and watched in fascination as her arms grew thicker, and thicker; bulging and growing. Henry seemed so much smaller now. So much further away. With newfound strength she pushed again. This time Henry disengaged from her udder with an audible *pop* and a surprised grunt as he fell back on his ass, squashin his tail in pain.
As he hit the ground Henry's eyes widened in surprise. Standing over him was a giant, only, it had the face of his daughter, and the curves of a goddess. Somehow, though he was sure they were still the same size, her massive udder and tits now seemed to fit her body, sticking out and curving her in exactly the right way.
Jamie may have been an Amazon, but Jess must have stood well over 7 feet now, and with a massive mass of muscles, underneath a layer of curvy womanly fat. Even her hands and feet had grown to match, looking powerful, and now ending in blackened, but still human, nails.
Henry's jaw dropped as the huge creature moved to stand over him, and then with ease and bulging thigh muscles squatted down, pausing half-way to grab his bull cock and guide it into her enormous pussy. Her udder landed heavily on his chest.
Jess left out a soft content sigh, that was completely at odds with her new size, as she felt her Dad finally slip into her. This was better. She felt strong. Powerful. Like a beast of burden. Like a beast.
"Not your little girl now!" She cried. Using her powerful legs to bounce up and down. Each movement raising her udder until it was barely touching Henry's chest, then slamming down, leaving all of it's soft squishy mass envelop his chest. Squirts of milk leaking out and drenching him in sweet warm fluid. "I'm your Big Girl now Daddy!" With two enormous hands she took her father's growing tits in her palms and began mashing them roughly into Henry's chest.
Henry moaned at the assault on his senses. This was all too much. The pressure in his head had reached a peak, and as he writhed and turned his head he could feel new inertia and momentum in the weight of the horns that stuck from his head.
It wasn't the only thing growing though. Beneath the strong hands of his daughter, he could feel his chest swell and grow with every breath. Each rise of his chest produced a new swell in them, increasing the pleasure radiating in to his core from them.
"Mmmmm... Nice..." Jess grunted, as she watched Henry's tanned breasts grow into soft E cups. She pulled away for a moment to let them fall and regard them. Heavy they lay flattened against Henry's chest, nipples utterly inhuman already, having turned to dark brown teats. With deft, thick fingers Jess grabbed them and pulled. All at once Henry's world exploded as she pulled on his teats. New sensation, driven by newly formed nerve endings flooded his brain and he bellowed in pleasure.
"Hnnnmmoooo!!!" He called as his behemoth of a daughter rode him to orgasm. Twitching moaning and mooing, he barely remembered the next minute or so as he first emptied himself inside her. Then barely registered the weight of her disappearing from his hips, only for his world to plunge into darkness as a musty, slick, sticky mess was pressed into his face, then ground up and down.
----
Jamie watched in fascination as Jess ground herself to a grunting orgasm on Henry's face. Locking in her new changes as an almost 8 foot tall behemoth. She turned back around to the other two, catching Melissa's eyes, as a furred, dog faced woman panted on the ground, not able to rise in the afterglow. Beside her Joan struggled on all fours to move around, slipping, cursing and bleating in frustration as she tried to get the hang of it.
Rock hard and pussy winking, Jamie sighed. Everyone here was utterly spent, and she had no one to relieve herself with. She grabbed her cock, stroking it once.
"Fuck. Guess I'll have to have a Hand Solo instead." She grunted.
A noise then, from the open doorway that Jess and Henry had come through, rooted her to the spot. She felt it in her core. Shooting all the way to her womb.
"HEEEEE-HAAAAWW".
Jamie shuddered happily.
"YIP! Whaa... donkey doing here?" Melissa panted, surprised, seeing Dakota in the doorway. "Go, shrrooo! Ruff..." She growled out. Then slapped her hands over her mouth, mortified at making animal noises.
"No. She doesn't go. Dakota stays." Jamie grinned. She handn't seen her mate in weeks. She'd been worried if something had happened to her. But now she was here, in the flesh. And looking at the slick cock slipping from the sheath, ready and rearing to go. Jamie was so happy to see her mate, the father of the unborn foal in her stomach. Her nipples began to ache and dribble milk at the mere sight of his cock. She could barely keep the excitement in her belly from overflowing. Family and expectations be damned, she was fucking this donkey right here and now.
"Hey you know those stories you hear of places in Mexico that have a donkey show?" Jamie asked, looking around at puzzled and confused faces.
She didn't wait for anyone to answer. "Well today you get to see one right here." She smiled.
