Henry kept cuming into his brother's ass, meanwhile, Harold's 2nd stage of changes started. Harold unlike Henry hadn't been lucky enough to find a man for him. while he was a woman he had dated and even had sex sometimes. but nothing long-term. he had thankfully gotten a job at a local cosmetic company and met her manager. Sarah was a kind woman who had taken under her wing, she idealized her. unfortunately, a fire had broken out and shut down, and it would open back up in 6 days. he had been watching TV that day when he looked at his phone and saw his sister's profile had completely changed. Instead of the mirror image of herself, she expected there was now a 10-foot anthropomorphic nude male bison with a green gym mat over his crotch. the name of his sister was changed from Helen Allaband was now Henry Bisonman.
she quickly contacted Arthur and asked why his sister had photo-shopped a bison on 2 legs and changed her name as well. Arthur then told her that was really Helen and she had changed into the Buffaloman she saw in the picture. not believing him she said she wanted to speak to Helen face to face. Arthur then told him to go to their apartment and talk to him. he drove over then entered the lobby, he then headed to the elevator but stopped when he glanced over to the pool and saw said Buffaloman swimming. he then proceeded towards the doors a gave them a knock getting the attention of the anthro. he then entered the outdoor pool area and got confirmation that this Buffaloman was indeed his sibling. he listened to his sister-turned-brother explain everything that happened to him.
he soon saw the mushroom head of his cock slowly rising. soon the red trunks ripped apart and Henry asked her if she'd help relieve the pressure. due to the musk coming from his dick Hannah quickly agreed to allow him to penetrate his ass. as they cummed Hannah's body rapidly became that of a 25-year-old man. as he transformed both the brother's cum soon flooded the pool area now up to his chin, but not for long. his cock grew from 10 inches to a foot to 2 feet then grew to 3 feet before stopping at 4 and a half feet long. his balls swelled to match and his blond hair turned light brown fur and became even thicker. his bush turned into thick light brown fur. now that their dicks were the same size their cum output doubled
his pelvis and butt soon got covered in short ruff dark brown fur as a tail grew from his spine. a mass of long dark brown fur grew at the tip. His thighs grew larger as dark brown fur grew, his height going from 6'2 to 6'6 causing him to rise slightly above the cum now barely covering his shoulders even as it rose. his calves grew to compensate and grew fur, his calves ballooning up and becoming furry bringing him up to 6'8, giving him an unguligrade stanch. his feet shifting to the balls of his feet as his toes split into two groups, his nails swallowing his toes, becoming hoofs. he was now 7 feet tall.
his waist expanded, and his 6-pack grew more abbs giving him a 24-pack in 4 rows of 6. his treasure trail turned into thick light brown fur as darker brown fur spread everywhere else. his chest expanded, his pectorals pushed further out from his body and his shoulders widen to 4 feet long. his chest hair became thick light brown fur completely covering his pecs, it continued to spread covering his upper-sides, then his upper back, and some of his mid-back. his height increased by 2 feet making him 9 feet tall. the cum was now only up to his and his brother's waist, now the cum had started spilling out over the 7-foot tall concrete wall. then his pit hair turned into thick light brown fur swallowing his shoulders and connecting to the fur on his chest, his upper arms got covered in thick light brown fur as his biceps swelled with muscle.
his elbows growing light brown fur as they increased in size. his forearms became even more muscular as dark brown fur grew on them. his hands increased again, his nails swallowing his fingertips. his neck then thickened and his addams apple became even more pronounced before thick brown fur grew over his neck completely enveloping it. his face pushed out into a short blunt muzzle. his nose sinking into it becoming large and the color changed to a dark brown. his rounded out as his eyebrow ridges became more prominent. long black horns grew from above his eyes and curved up. The hair on his head became large and shaggy before becoming light brown fur. thick dark brown fur grew over his face ending at his chin giving him a small beard of fur.
they both fished cuming and Henry pulled his dick out of his brother's ass. both Henry and Harold then took a look around seeing they were both standing waist-deep in their own cum. " huh I guess it's true about anthros cum more the longer it takes to masturbate" Henry said. "yeah" Harold said his voice having the same deep grunting sound to it as his brother. now Henry took a good look at his alpha bison brother, he now looked like a spitting image of him from horn to hoof. "hey Hannah you OK, I know I asked you if it was alright. but, that was before I realized how much I would cum." Henry said. "it's no prob bro" his brother replied suddenly using slang he heard bros say." I can see why you like your new look."
" oh, by the way, it's no longer Hannah, it's Harold buffalo" Henry couldn't help but smirk " really dude your last name is gonna be what you are?" he asked. "well my last name was Brown so not much wordplay there." "true man, you know why don't we go to my apartment and take stock of our bods," Henry said "that sounds sick bro, let's go" his brother agreed. Henry grabbed his cum soaked stuff and headed to the door. he pulled open the door letting the cum flood through the lobby soaking everything in the thick goop. the buffalo brothers went to the elevators and entered them. Henry pressed his floor. once he entered the hole he had for a front entrance.
after setting his stuff down he then proceeded to the bathroom with Harold following. he was thankful that he had such a big mirror, it allowed him to look at his brother and himself at the same time. they compared themselves and saw very slight differences. Henry's light brown fur was a mix of an Afro and rockers hairstyle his horns also had more scratches than his brother's. Harold saw his horns were also less than half an inch shorter than Henry's. he also saw the birthmark altered his fur, he now had a small shape that looked vaguely like Florida, and it was now light brown fur.
after that, it was getting late so they...
