Jess was huuuungry. Losing herself in translation of the tome she hadn't eaten in hours, not since breakfast, which had finished up the last of the vegetable stash she and Henry had stashed in their cottage. Stomach grumbling in displeasure Jess had gotten up to journey back to the main cabin to get supplies.
Henry, translating on the bed, watching his daughter's bulk of tits and udder struggling to get up grinned. She had completely filled out now, all curves and softness. No longer the gawky skinny teen. Her feeding had turned her into a curvy goddess, but with her short size and massive tits/breasts, it was making it slow for her to move around.
Being the gentleman that he was, Henry had offered to go with, to the kitchen. That's how both found themselves in the doorway staring, open mouthed, at the ongoing threesome.
Melissa was on the bottom, on her back, nose black and alternating between panting and licking the dangling breasts of Jamie.
Jamie was ploughing into his ex-girlfriend, missionary style, moaning and giggling in happiness as she bounced between Melissa below her, and Joan behind.
Joan stood, bow-legged, hands on Jamie's massive thighs, bleating and thrusting away.
"Oh God..." Jess breathed. Hand rising to mouth. The smell of sex was already overpowering here. She had to leave! Only, her body wouldn't let her, legs rooted into place, she felt sluggish all of a sudden; full, heavy, and her eyes refused to look away. Her cheeks reddened and she began to get flush. She couldn't leave, she felt close to bursting. Her chest was sooooo heavy. Her udder almost dragging her down.
Henry stood open mouthed too, but had a slightly different reaction. Sure Jamie's ass and mare-pussy were inviting, he knew that first hand. Sure Melissa was a fine looking girl, curvy, dusky and fit. But Joan... That smell... The smell of goat assaulted his nostrils. Too ingrained was his revulsion at everything that had happened. It kept him sane enough to pull his eyes away, away to Jess. That would be safe. Only...
Jess's face was flushed red, pupils wide, mouth parted and lips almost pulsing they were so full. He coulld see her nipples and teats taut under her dress, tail swishing underneath it, unconciously spreading her pheromones.
Her horniness making her look like the perfect mate. Now that. That was enough to get Henry's blood pumping. He began to get visions of the last time they fucked. Jess, a bag of tits, curves and that pussy... and she was even more curvy now. God he wanted to fuck his mate, he'd been wanting it all week. Maybe...
A particularly loud bleat from Joan snapped him back momentarily and he reached out, grabbing Jess by the shoulder and spinning her.
Jess looked up at him, eyes slowly focussing on him. God her dad was a hunk, she felt excited, wet. Remembering how he had basically thrown her aroung the room made her chest heave in excitement. Only that made her teats rub hard against the fabric of her dress; and they were sensitive. Good God they were sensitive, they felt like pressure was bulding behind them and they were going to expolde. Henry pleaded "Jess we gotta g-g-g... oh."
Jess followed his eyes down to her chest. Spots were forming on the yellow sundress fabric pulled taut by her nipples. Dark and quickly spreading.
Jess looked up at him in pained surprise, face wrinkled in pain and pleasure. "Hnnnnmmm." She moaned piteously and began scrabbling at her dress straps. "N-need out!" She had to get out of this constricting thing. "They need to c-come o-out!" She stuttered.
Henry panicked. If she undressed, that would be game over; he knew he wouldn't be able to resist her. In a frantic panic he grabbed her hands and held her arms down. The feeling of him grabbing her sent a shudder through Jess, and her knees almost buckled.
"No Jess" Henry began, weakly, "We have to get out of here of we'll change again." his eyes pleading with hers
She groaned piteously again, weakly pulling against him. The front of her dress was going to explode. It was holding back her humongous tits, growing, groaning and leaking. They were constricted so much it hurt, it hurt bad.
"Daddy please! Let them-m-mmmooout." The entire bosom of her dress was now sodden. The sweet smell of warm milk in the air. Henry gulped. His daughter was lactating like a cow. How sweet would it be to be sucking from those amazing tits, from her udder. He looked down, there were dribbles of milk pattering onto the ground from under her dress. She was leaking like poor plumbing. She looked miserable there, constrained. 'It would be too long to get her to calm down again', Henry thought. To get her back to the back of the cottage, fill a bucket with cold water...
Better to fill that bucket with milk. Henry's grip loosened, Jess's face instantly showed relief and gratitude, and she began trying to get her dress off. With her thicker body, however, she was struggling to reach the zip at the back.
Henry was about to help when he saw movement in the corner of his eye. He turned to see that Jamie had extricated herself from the threesome. Making Joan stumble back a few feet in surprise, and Melissa moan in unfinished disappointment.
She stood tall, if a little unsteady, feminine face beaming in a pleased posture, massive horse cock and balls dribbling an obscene amount of juices and slowly retreating into it's sheath.
It took Henry a moment to notice her change though, her hoof-feet, had morphed, ankles stretching back and lengthening, calves shortening as her posture changed. She now stood fully digitigrate. And by God did it make her look good. She stood almost a foot taller, now taller than Henry, and her posture emphasised her bosom, and her ass. Both magnificently curved.
Slowly and carefully she sauntered over to the pair. Eyes on Jess. "You poor thing sis! I know what that feels like." Reaching the two cows, Jamie wobbled, unsteady for a moment, then steadied herself, reached out, and in one fluid motion, unzipped her sister.
There was almost an audible pop as the taut fabric flew open and Jess beleaguered tits spilled half-free. Jamie and Henry each helped her with an arm hole, freeing her from her straps and letting the dress and tits finally fall free.
"Wow!" Jamie exclaimed. 'Wow' was right, Henry thought. Even though Jess had gotten a little bit of pudge on her belly, her tits were now soo big, that even standing, they rested fully on her udders. Each one must have been at least half the size of her udder, areola the size of dinner plates, and nipples as big as a small erect cock.
Jess grabbed her dripping nipples and began to pull, letting jets of milk fly through the air, landing with a soft patter. Jess's eyes crossed, so good was the feeling of relief. Jamie and Henry began rubbing her soft back, gently and cooing.
"Let it all out babe." Henry softly encouraged, while Jamie happily chirped, "See! Doesn't that feel good?"
It did. It felt amazing, but... It wasn't enough. She still felt ready to burst. Especially her udder.
"Hnnn... Sooo full still... M-my udder." She moaned, furiously yanking on her tits, frustrated that she couldn't get at all 6 teats at once. "Help me daddy!" She moaned. "Milk me!... Please!"
Lust had fully taken over again; Jamie and Henry shared a look, Jamie smiling, she knew this was ending in a good threesome. She slipped behind her now, even shorter sister, and snaked her arms around to take her the milking of her tits from Jess. Jess tried to turn but Jamie whispered in her ear. "I can't kneel with these knees, you and Dad will have to milk your udder. I'll milk your tits." She leaned in, pressing the softness of her breasts into Jess's furry spine. She giggled at the feeling of Jess's tail tickling her horse cock and balls. Jess was just so soft. So feminine. Jamie was so jealous of her sister's curves. "God you're sexy", she whimpered as she leaned and kissed Jess's neck from behind.
Jess leaned into it, never breaking eye-contact with Henry in front of her, as she reached down and too her top two udder teats, one in each hand, and began to milk them. "Daddy, please milk the other two." She gestured down to her bottom two teats, completely untouched, bouncing and flicking milk with the motion of the rest of the milking. It looked delicious. Eager Henry dropped to his knees, took one in his right hand, squeezing and jerking it, and the other he fed into his mouth; greedily sucking down the warm sweet fluid.
Now with all teats occupied, Jess finally felt less frantic and a wave of calm came over her. The feeling of being drained of milk was so very calming, erotic, and fulfilling. Her brain screamed that this feeling was something she should crave, to seek out, to live this pleasured serenity. Not the stress of the outside world, but the quiet eroticism of this place. She knew it was wrong, and not what she should be thinking, but she thought it anyway. Her eyes fluttered closed and she just let herself enjoy this moment. Just to let herself be milked.
