One week later

"Ah! Ah! Oh fuc- Moooooo!" Sarah moaned as she came for the 4th time since her husband-turned-bull had started railing her right there in the kitchen.

They had finished with dinner, and as soon as Sarah was done with the dishes; she was jumped by Tom who quickly undressed her and pawing at her enormous milky udders, inserted his, now 15-inch bull cock straight into her dripping pussy, wasting no time in thrusting away like a wild animal. Her pussy was stretched far and wide with his insane girth, making obscene squelching noises as if it was being turned inside out with each pull and thrust.

By this time, they had changed many positions. Tom seemingly hell bent on enjoying his cow wife in whatever way possible, and with his new body, the possibilities were quite numerous. Currently, Sarah was completely lifted off the ground, Tom's beefy hands supporting her thick creamy thighs and ass, while she wrapped her legs around her husband's back, as he fucked her standing up, using his new improved strength to shake her up and down on his meatstick.

Sarah couldn't help but marvel and get extremely aroused at how Tom had changed in the past week, her milk changing him more and more, as he drank it, and he had drank quite a lot of it in the past week.

Tom was now nearly 7 feet tall towering over his 5'11" wife, his dark brown hair had grown a bit framing his now bull-ish head with two long, curved horns growing from his forehead and his human ears being replaced by cow ears just like hers. His face had grown a muzzle just like hers, though distinctly wider and darker. Thin, coarse brown fur now covered the remaining entirety of his head and neck, going down to the middle of his chest in a V-pattern.

Speaking of his chest, his pecs had grown significantly, almost as big a professional bodybuilder's now. His shoulders and arms now covered with the same fur, and had similarly grown quite huge, explaining the strength with which he was able to lift and fuck his wife, who was definitely much heavier than her previous human form. His back and upper torso had also developed, hardened and widened significantly, overall giving him an imposing, hyper-masculine figure, something which his wife heavily appreciated and let him know every chance she got.

His stomach was no longer flabby, having burned away all his extra fat from his human form. Who knew fucking his wife everyday would be such a good core workout? Well either that or it was because of the increased metabolism of his body. Nobody knew. But he was now sporting rock solid 8-pack abs you could grind metal on, with a bit of fur expanding out from near his belly button.

His feet had turned into hooves just like her, but his legs were covered with huge rippling muscles clearly defined through the thick fur coating his legs, looking like tree trunks, and just as strong and steady as he thrusted his muscular hips up into his wife. His bovine tail now always lazily swishing about behind him at all times.

The biggest change however had to be his cock, while earlier being pretty average in the department it had grown and changed drastically. The shape now distinctly equine, with a dark brown sheath covered with light fuzzy pubic hair at it's base, which quarter-way down grew into a mottled-pink shaft ending in a flared flat cockhead, which was currently planted deep inside his wife's womb.

It was as thick as his new forearm if not thicker, stretching the poor cow's vagina to the absolute limit, and making sure she felt how it rubbed and stimulated all the pleasure spots inside her effortlessly with his rugged veins, while making her pussy feel tighter than a virgin on his dick, no matter how many times he fucked her.

His balls were as big as cantaloupes now covered in a light fuzz, hanging down mightily below his crotch. The leathery scrotum now pulled taut over his bloated balls as they continuously spanked into his wife's soft butt like wrecking balls leaving clear imprints while grumbling, roiling and churning incredible amounts of virile sperm, as they seemed to permanently do nowadays, and prepared to deposit their massive payload soon.

Tom looked sexier than ever to Sarah, a pinnacle of masculinity, and he certainly wasn't complaining about how he felt in his new body since the transformation. His body was now always brimming with strength, energy and lust, the latter of which he was more than happy to unleash on his slutty cow wife.

Sarah came again as she was manhandled by her bull, freely letting out another shameless moo, no longer feeling insecure since both of them were now in the same boat. Tom getting close himself, pulled his wife off his monster. His cock throbbed angrily leaking an absurd amount of precum - that would put multiple, full human loads to shame - begging to be let back inside the tight, wet hole of his anthro wife.

Tom put Sarah down, her legs were still wobbly from the intense mating, so he turned her around and grabbing her outstretched arms behind her for support, he slammed his cock back inside with all his might. The **** would have been too much for a normal person, but he knew his wife could take it, even though he felt his cock plant itself deep inside her womb, a place it frankly shouldn't go into, but Tom relished the tightness it provided, the pleasured mewls and whimpers his wife let out were just the icing on the cake whenever he penetrated her so deep that one could easily see the distinctly large bulge projected on her pudgy stomach.

Tom enjoyed the sight of his wife's soft bubbly ass jiggling like jello, with every impact of his hips against hers. Her milky boobs were big enough that he could see them shaking in front of her from behind her, giving him generous glances of her sideboobs. Sarah's legs were basically putty at this point, as she was continuously assaulted from behind, at this point she was basically only held up by the throbbing iron-like shaft inside her. Her clit was being spanked repeatedly from her husband's bull balls triggering another orgasm, as her legs shook and she let out another moo. The tightening of her pussy however was too much for Tom, who was already on the brink and was now finally pushed over the edge.

"AH! Fuck! Sarah, I- I'm... ah... CUMMING! Oh! Mooooooooooo!" Tom cried out in his deeper, huskier new voice while throwing his head back and letting out a deep growling moo, as he felt his heavy muscular ballsack tightening and squeezing, and his shaft somehow grew even harder and thicker, and he gave one final mighty thrust to plant himself balls deep inside his wife. His back arched forward, and grinding his cock as deep as it could go, meaning Sarah was now fully lifted off the ground by his throbbing cock alone - her womb impaled on it - making sure she took every last drop he was about to give her.

"YES! YES! F- AH! FILL ME UP, YOU STUD! OHHHHH! MOOOOOOOOOO!" Sarah joined in as the anthro couple moo'd together in sexual bliss. The house almost shaking due to how loud they were.

Tom felt his legs shudder as what felt like a fire hose went off between his legs. His cock wildly bucked like a raging bull inside his wife, proudly showing off it's inhuman, diamond-hard strength as it emptied his overpacked, virile balls directly into her womb, while keeping her feet off the ground.

Sarah felt like she got punched from inside her gut, but she had come to love the feeling as she felt herself being lifted by her bull's penis alone, while her tummy bloated with his strong, thick and heavy seed. The sensation caused her to have another orgasm in quick succession. Her mind went blank and her eyes rolled back, as she felt her womb expanding to contain the flood of her bull stud's potent seed. Her already chubby belly grew bigger and rounder as her husband emptied his balls inside her. By the time he was done, she already looked like a full term pregnant anthro woman carrying an entire litter, her heavy breasts and udders completing the matronly breeding cow look.

Tom finally pulled out of his wife's warm, gooey snatch, surprisingly little cum leaking out of her despite the gallons he pumped into her. Her cervix apparently squeezing hard to keep most of his pudding-like, creamy load inside her, much to Tom's delight. Seeing Sarah was in no shape to walk, he scooped her up in a bridal carry, his new improved body making it an effortless task despite her increased weight and his extra payload inside her, and carried her to their bedroom.

Sarah had regained some sense after the intense session, and wrapped her arms around her bull's thick strong neck, nuzzling into his fur. She had never felt so loved, safe and protected as she did in her husband's arms.

Reaching the bed, he put her down on her side and cooped up behind her, hugging her thicc frame from behind while spooning her. A large paw resting on her bountiful boobs as he held her close. Tom didn't want anything else other than his wife to be happy and feel loved. He still wondered if she had some reprehension about how he had changed her and how she felt about all this, so he turned back to the coin on his bedside desk.

"I wish whatever is my wife's ideal fantasy about us, it comes true tomorrow morning."

Putting back the coin, his wife voiced her disapproval of not feeling her bull's warmth behind her by pushing back and letting out a pleading moo. Tom quickly went back to soothing and cuddling his wife.

"I love you." Sarah mumbled sleepily, snuggling closer to Tom.

"I love you too... so much. I promise I'll always love you and protect you." Tom replied back softly.

"I know you will. My big, strong bull." Sarah smiled and turned back to plant a kiss on Tom's snout before they both dozed off for the night. Tom's hand gently but possessively massaging Sarah's rounded belly.
