Steve smiled now and grew excited when he selected to become a female cerberus. Steve always wanted to know what being a woman would feel like, as well as multiple heads and he's always been a furry fan.
When Steve clicked the option immediately his body began changing. Steve’s body started growing and his arms and legs swiftly sprouted black fur on every inch of them. Steve’s body grew until he was about 7 foot tall, and his arms and legs started getting slender, but at the same time their muscles bulged out making them buff and powerful.
Steve’s fest bursted through his socks and shoes and grew into giant paws, and his nails became curved claws. Steve’s shirt already felt tight against his large body, but now the fur covered his torso and he felt really hot. In fact, Steve panted and when he did his tongue enlarged and stuck out of his mouth, and soon it grew out into a canine muzzle. Still panting, Steve’s head reshaped into that of a dog and his vision of color faded, but his other senses only grew with that change with his newly pointy curved ears, as his large and wet black nose.
It was then that Steve felt saw tiny orbs forming down his front and expanding in size. Two of these mounds were underneath his shirt and caused it to tear off of his body immediately as two watermelon sized breasts broke apart his shirt at the seams. Meanwhile all of Steve’s other breasts grew to ample size to match his top set of breasts and then he felt the fur reach his pelvis.
Steve’s hips slowly grew wider and destroyed both his tight pants and underwear in the process and his ass bulged out giving him busty curves along with a muscular body. Steve immediately grabbed his shrinking dick and balls then began jerking off as much as he could before it disappeared. At the same time a furry appendage that was wagging happily sprouted above Steve’s cushioned ass, and suddenly he felt pressure coming from his shoulders. Steve then orgasmed as his dick and balls shrank into a feminine slit between his legs and he howled spewing a mix of cum out of his diminishing dick, and new cum from his or her new slick slit between her legs.
Steve howled as She orgasmed then two heads appeared to her sides and moaned loudly too. "Aww yeah! Feels so nice, and dirty." The left said then the right howled,"Awooo! Yeah, give it to us sister!"
Steve paused at this then he removed his hand and asked,"Sister? Wait what’s going on here?" The heads paused then looked at Steve and then unanimous smiled and barked,"We’re you silly!" The left head then licked Steve and said,"More specifically we’re biologically part of you, so we’re you, but not at the same time." The right head then added,"To us we’re sisters, but to others we’re one. Can I see that paw by the way?" Steve paused and saw the right head lick her lips and Steve nodded reluctantly and lifted her soaked paw up to her. The right head immediately began licking with glee and made sure to clean between Steve’s fingers from all of the cum that was on there.
"Oooh, nice taste!" The right head barked then the left head whined,"Can I do that next?" Steve paused then nodded and said,"Sure, but....we're sisters?"
"Hell yeah!" The left one barked then the right one smiled and barked,"Damn, we’re one fine and sexy piece of bitch ass! Can you find a mirror?" The left head then nodded too and barked,"Yeah, please, we want to see how we look." Steve shrugged and smiled,"Sure, anything for my sisters."
Steve walked over to her closet then opened the door to a full body mirror and she turned to the side and the other heads smiled and barked,"Yeah!" The left head smiled and said,"We have a nice big ass for show!" The right head then barked,"Forget that! Our breasts are huge, and we have so many of them!"
Steve’s tail was wagging with excitement now and she cupped one of her breasts and gave her ass a nice smack causing her heads to yip, but then they smiled and nuzzled Steve. "Oh, well you’re sure excited." The right head said then the left head looked over at the computer and cocked herself to the side then she asked,"What’s that on the screen?"
Steve paused then she walked back over to the screen and noticed a new menu that showed a picture of her new form. Now there was something new that read,"Additions, one free per life change" and there was a new list that seemed to have all sorts of naughty suggestions.
"Oh wow, what’s this?" The right head asked then the left head barked,"I want this one!" Then Steve spoke up,"Hey let’s see what we all want now. If not we were just browsing." The other heads nodded then Steve took hold of her mouse then browsed what was there. Eventually she found something she liked and she selected an option, and that was.....
