Joan's goat ears twitched.
Somewhere close, someone was fucking, she could hear it. With a bleating grunt, she dropped her brush and rolled her eyes, looking down at her dribbling penis. Gone a few weeks now without release she was almost constantly hard, and, as such, her next change was always primed and ready to get locked in. The new larger ears were very sensitive, able to pick up most sounds in the Cabin as if she was standing right beside them. For weeks now she had been waiting for Melissa to knock on her door, to tell her that she had seduced Henry, put a wedge between the two cows, and was there to be fucked by her.
Joan bleated happily, that sound, that cry, that was Melissa. She must have finally done it. Finally, sweet release. Cock rock hard and bouncing with every step, Joan slid from the room.
Every step she took as gingerly as possible to avoid making noise with her hoof-feet. With each step her cock bubbled more and more pre-cum at the thought of cumming in that hairy bitch, leaving a slug-like trail behind her... She wasn't going to last.
Excitedly she reached the sounds of lovemaking in the kitchen and cracked the door open. Her jaw dropped at what she saw; not Melissa seducing Henry, rather Melissa squashed underneath Jamies massive ass and thighs, being thoroughly ploughed by his horse-cock; happily moaning and whimpering as the giant shaft squelched into and out of her, and the massive testicles slapped audibly against her ass.
Joan saw green. This was not her plan! This is not what she wanted. Jamie and Melissa weren't supposed to be getting along. Melissa was supposed to be driven to seducing Henry and then coming to her. It was time for her to fuck! She deserved to get Melissa. Melissa was hers.
Green turned to red and Joan entered the kitchen, ready to give them a tongue wagging. Instead of shouting though, her cry came out as a strangled, frustrated bleat.
"Bl-e-e-e-e-e-eeehhh!" She cried, stomping a hoof, causing her fat cock to jump in excitement at the motion; as the thrusting slowed and Jamie's horse ears swivelled on her head to the sound of the bleat. Underneath her, Melissa peeked out, eyes lidded with pleasure. Joan now saw that her soft brown fur had risen past her navel, turning the girl into some strange, half bigfoot. Her nose twitched too, the modified, more sensitive organ picking up the two distinct smells. Deep and musty from Jamie, like hay and the smell of dry earth exposed to rain. Sweet and tangy from Melissa, like over-ripe fruit. The smell of sex was the final straw for her dribbling cock.
Without touching herself, or any stimulation provided by touch, Joan began to cum. Weeks worth of it pent up and boiling for days. She bleated again in frustration and pleasure as the first shot made her knees buckle and she had to hold on to the back of a chair. A thick yellowish glob shot out as she humped the air, sailing a fair distance, and splattering directly into Jamie's face, just as she fully turned. She flinched at the warm semen struck her face but quickly recovered. Well in time to see the third shot sailing again through the air, second having hit the ground with Joan doubled over at the time. Jamie instinctively twisted her torso towards it. 'Mares love cum, I'm a mare!' She thought, as the more powerful jet splattered against her drained sagging breasts.
Glancing off Jamie's breasts, some of the cum splattered onto Melissa's fur covered belly. The smell of Joan hit her like a tonne of bricks, her nose instantly morphing into that black, wet, dog shape. Without a snout to go with it, her mouth took on a pug-like "w" shape. Nostrils flared as she took in the familiar smell of the goat-lady. Her hands ran through her fur to coat them and lick the amazing smelling fluid off her hands. Unfortunately though, the cum was matted in, and not easily wiping off. "Neeeeeed more!" Melissa growled, tail frantically wagging between her ass cheeks.
Joan and Jamie meanwhile had come to an arrangement by then. That arrangement was that a grinning Jamie had agreed, amicably, to be Joan's canvas; and Joan was to only use one colour to paint, cum colour.
"Bleh. Bleee-e-eh. Bleh. Ja-aa-amie. F-f-uck." Joan was now holding on to her cock, standing right beside Jamie, and hosing his daughter's chest with cum. Jamie for her part was stretched, chin raised, pearly whites showing in a happy grin. Hilt deep in his ex-girlfriend or not, being hosed by cum made her feel more like a woman, a mare, a slut. That feeling made her happy.
Eyes closed Jamie didn't have time to see Melissa rise until her hands were on her arms and Melissa was twisting her around. The brunette growled and buried her head in Jamie's heavily dangling breasts and began eagerly lapping up Joan's cum, the gloopy, salty semen mixing with the creamy sweet milk dribbling from Jamie's lactating breasts.
"NNyaaahhh!!" Jamie cried out. Ecstatic at having someone so eagerly sucking and licking her heavy breasts. Covered in semen, having her breasts sucked. Cock buried hilt deep in her ex-girlfriend notwithstanding, Jamie was really beginning to get a feeling for this woman thing. Only one thing missing. She glanced behind at her mother, the one who had kicked all of this off by getting her to go to the barn to get fucked by Henry. Jamie knew full well that Joan had only done that to try to get her to tempt Henry into fucking her and upsetting the cattle some more. Jamie should have been furious, she knew, but the change and her revelation about wanting to be a woman made her forgiving enough to let it slide.
Joan's plan, regardless, hadn't worked. Jamie had seen Henry and Jess wandering around and interacting since, they seemed closer than ever, it must be driving her mad.
Joan now lay on her ass on the ground, cock deflating and drooling leftover cum all over her own crotch tits. Her eyes were still rolling and pupils blown from her orgasm, new locked-in ears twitching. She really was turning into a creature Jamie thought. He felt sorry for her, but also frustrated that she was still scheming, even now. Why couldn't she just let everyone be happy? Let all the fucking occur naturally, rather than try to force situations.
'Like now' Jamie thought. 'Having someone suck my tits is making me feel like a woman; but this stupid horny cock, fun though it feels, isn't making me feel very mare-like. Maybe mum can help?'. Still connected to Melissa and thrusting away, Jamie shifted forward, knocking Melissa back down and assuming the missionary position again. This time though, she intentionally lifted her ass into the air, puckered asshole and winking pussy wiggling in the air between two thick ass cheeks.
"Come fuck your daughter!" Joan heard Jamie cry out. Eyes coming back into focus, the first thing Joan registered was two tremendous globes, two amazing ass cheeks, bouncing up and down in front of her. In that grand canyon of a cleft between them she could see the most delicious, jet black and shiny doughnut; and underneath that doughnut, a wonderful cleft, winking open and closed every few seconds to reveal a bright pink interior.
Though just done with an orgasm, Joan was so horny, and had been deprived herself so very long, that the sight of this beautiful creature instantly brought stirrings to her crotch, and her cock began to resurrect.
'Oh my God... Jamie... She's so fuckable right now.' She thought, though her mouth again only managed an excited "Ja-a-a-ame-e-e-e". As she crawled towards her daughter.
A few moments later Jamie jumped as she felt a cold wet nose pressing against her asshole. She smiled, Joan had gotten the message. She wiggled for a bit as she felt her mother snuffling around for a bit, licking her ass-hole and cleft. Penetrating both in turn with her muzzle and tongue.
"C-mon Mom!" Jamie called, she was a woman, she needed to be penetrated. Joan got the message and stood on shaky legs. Cock still smeared in her own cum, she grabbed Jamie by the jiggling ass cheeks, and began smearing her batter all over Jamie's doughnut asshole, lubing it up, before aligning and letting herself sink deep into her daughter. She sighed in relief, she'd wanted to sink that cock into someone for soooo long. As she began to plough away she didn't even care that it was her daughter, once son that she was fucking. She didn't care that in her haste she hadn't even stuck it into Jamie's vagina, instead opting for anal. She didn't even care that she wasn't staying commanding and master-like in front of the panting and gasping Melissa, now with her black dog nose fully changed. She didn't care in the slightest that she could feel her two testicles drooping, becoming pendulous and heavy.
She didn't even care that there were two aghast cow people standing in the kitchen now, shocked, at the sweating, grunting, squelching threesome.
