Satisfied with the bearish changes to Cindy's brother, Bajoo quietly padded his way down the hallway to the bedroom where Cindy's mother, Sheila, lay sleeping. The former zoo animal could tell which door was hers from the feminine scent that was drifting from underneath the door crack, and his slimy ursine dick slipped out of its sheath at the thought of turning this woman into a proper mamma bear for her transforming cubs.
Although he was a grizzly, Bajoo was a thoughtful bear and he decided he didn't want to scare Sheila. Opening the door slowly so as not to make a sound, Bajoo slipped into the room -all seven and-a-half feet of him- and surveyed things. Cindy's mother was there sleeping in the middle of the room on her back, just as Bajoo's nose had informed him. Bajoo scratched his chin with a long fingerclaw, wondering exactly what he might do to infect her. After cocking his head and thinking for a bit, he came to a decision -one that would hopefully be very pleasurable for her.
As carefully as possible, the anthro grizzly bear lifted the covers at the foot of her bed and stuck his big head underneath. He slid his snout between Shela's smooth legs little-by-little until at last the bear's big black nose nose was practically touching her pubic mound. Bajoo paused for a moment and gave an exploratory lick with the tip of his tongue. Sheila giggled in her sleep. What luck! The female wasn't wearing any clothing either! Now emboldened, Bajoo gave her recently shaved pussy a long slurp with his bear tongue, his ample saliva quickly transmitting the animorph virus into her slumbering body. "Ohhhhmmmm," Sheila moaned, smiling as she slept. Bajoo could hear her pleased groan and encouraged at her response he began to sloppily lap at her pussy, his tongue occasionally entering her and pressing against her clit.
As Bajoo attacked Sheila's pussy with his tongue, he could tell even under the pitch black of the covers that a gradual shift was taking place. At every lick his tongue was starting to encounter lengthy hairs, the woman's shaved pubic mound gradually sprouting a curtain of soft silky fur. Still in a deeply slumber, Cindy's mother was totally unaware of the change that was taking place in her body but everywhere Bajoo's tongue traveled it was now encouraging the spread of shaggy bear fur. And, with the growth of her pelt, came a pleasing change in her scent. Bajoo's nose had at first wrinkled in dislike at the heavy chemical odor of soaps and deodorants that coated the woman's skin but as the seconds passed those artificial scents were being submerged in a sea of feminine musk that Bajoo's nose recognized as belonging to a deeply aroused female grizzly bear. Bajoo's cock twitched in response as rivulets of precum dripped down from its pointed tip onto the bed below.
Suddenly, another aspect of Sheila's new scent began to take shape. "Mmmmmfff. Grrrrrrrrr," Bajoo growled lowly as his furry balls churned. Not only was the human now well on her way to bearhood, but the pheromones drifting from the fur surrounding her sopping wet pussy were signalling to Bajoo that she was on her way to becoming a female bear IN HEAT. He couldn't hold himself back any longer and driven by his instinctual need to mate, the big brute removed the covers from the transforming woman and drove his throbbing bear cock into her sopping vagina. Sheila gasped as she felt herself entered, opening her eyes as she realized that a giant hairy....something....was fucking her. It was both terrifying and unspeakably arousing for reasons she couldn't fathom, her growing shebear instincts whispering to her that the beast raping her was healthy and virile and that she should submit to his mating.
Sheila's face was now level Bajoo's fuzzy pectorals with Bajoo's big bear belly pressing her down into the bed. She began to sense a cluster of swellings beneath her breasts and with each thrust of the horny bear she groaned as Bajoo's tummy fur smooshed against the protrusions on her stomach. Reaching down she confirmed what she already knew -that she had a set of nipples beneath her original pair, and yet another pair below that. She moaned in a combination of fear and sexual need at the alien sensation of Bajoo's fur rubbing across her four new teats as the skin beneath them bulged outward from the mamaries forming underneath. She knew now that her body was changing, being reshaped into something more fitting for the creature that was relentlessly pounding into her. The virus magnified her desires and the pleasure center in her brain suddenly went haywire as she felt her vagina begin to alter its shape and slide further between her legs until it was almost underneath her anus.
With this most recent change Bajoo's penis slipped out of her pussy and she felt an intolerable ache from the resulting emptiness. "Please. Oh, please fuck me like this," she begged, turning onto her hands and knees and hiking her bottom up to give the beast better access to her dripping snatch. It somehow felt right, more...natural to be taken this way. Sheila looked behind her and in the soft glow of her alarm clock the woman could finally see the silhouette of the great grizzly bear animorph who was fucking her. It was miles beyond any fantasy of which she could have ever dreamed up. "Yes. Bajoo will mate as female asks," the bear replied in a deep growling voice as his dick pushed between the darkening leathery lips of the woman's pussy. Sheila could only close her eyes and rock forward with the grizzly animorph's powerful thrusts as she moaned and panted, giving herself over to the virus.
Cindy, relaxing on the living room couch and surfing the web on her phone, could hear the loud lusty moans and accompanying low growls from the direction of her mother's room. Scanning the website of the local news station, she noticed a brief article about a mysterious break-in at the water treatment plant. Cindy smiled to herself. So that's what Brenda came up with in order to infect the rest of the city with the animorph virus. Very smart!
Realizing that the sounds from her mother's room could only mean one thing and that she probably wouldn't be seeing Bajoo for the rest of the evening, Cindy made her way to her own room and lay down on her bed. The teenager could still hear the growls of the rutting bear and the moans of her transforming mother though her wall. She imagined what their primal sex might be like and feeling horny, reached down a clawed finger to toy with her furry pussy. Bajoo had fucked her too, making her this way, but although she cared for him she wasn't jealous. Even if Bajoo wasn't really her mate any longer perhaps she'd be lucky enough to find a more available man in the transforming city; one who would ideally have cute half-moon ears and a handsome muzzle. She imagined the possibilities with her future unknown ursine boyfriend as she finally drifted off to sleep.
