Nikka silently moaned as pheromones wafted up to her nose as the mutant dog man started dry humping her leg.
“Please, you need it as bad as I do. Just bend over. I promise to knot you,” the mutant said groping a breast, popping it from Nikka’s shirt.
As the smell of hot musky mutant made her yearn for him, Nikka realized she needed to get out of there now, or she would soon lose all control.
“Please… back off!” Nikka said pushing her would be lover away, giving her a full view of his fully erect and popped knot canine dick. From the look on his disappointed face, she could tell the mutant thought he was walking out of there with two seeded bitches in his pack.
“Fine! Then go! B-before I lose control,” he said as he positioned himself over Mimi.
Racing to the door, the last thing Nikka heard before leaving the fouled vet office was Mimi’s excited yelp, followed by the wet sound of dick and pussy mashing together.
Slipping her breast back into its shirt, Nikka stepped outside to her town in mayhem. Mutants flooded the streets as uninfected and changing fled the city. Dodging mutants pinning down their victims, Nikka ran to her car as her pussy flared with need; now experiencing first-hand the pheromonal effect mutants used to seduce humans.
“Ha… oooh! I feel funny,” Nikka said to herself as she threw open her car door; a weird tingling numbing her butt and chest.
Hopping into the car, Nikka yelped in pain as she landed on her butt. Forced to her side, Nikka screamed as she peered down at her round ass to see her pants tenting heavily. Reacting to the pressure, the odd growth slithered and pushed further from her butt.
“No! Please, we didn’t even… wait,” Nikka said looking down at her pants where the mutant had dry humped her. Sure enough, she saw a large wet spot, a mixture of pre-cum and maybe even some premature cum rubbed into her pants.
“Ah! Can’t… hold…” Nikka grunted as the large growth pressed forcefully against the butt of her jeans. It wanted out! It hurt to keep it concealed. With no other option, Nikka placed a hand on each butt cheek. Then in one motion, she firmly pulled them apart. Between this and the pressure building beneath, a loud ripping noise pierced Nikka’s ears as her pants parted, her pussy and anus visible for a moment. But only a moment as Nikka’s long furry husky tail slithered free from her butt, wagging freely out the door as though telling the world of Nikka’s infectious nature.
“I have to get out of here!” Nikka whimpered, knowing if she sat any longer an infected mutant would smell her canine scent and look to breed her. Tucking her tail under her butt, between her legs, Nikka closed the car door to find another shocking change. Buckling her safety belt, the fabric tightened around her breasts. But feeling her right breast above the crossing belt, she peered down to find a second set of breasts swelling beneath her original. Feeling what she could only imagine as a third set slowly forming, Nikka put the car in gear and sped off as her mutating sex drive grew curious how mutant sex might feel.
10 minutes away from home, Nikka moaned and shifted uncomfortably in her seat. Her body begged for her to pull over and play. Overheating, her tongue hung from her mouth as she panted.
“How am I gonna sneak into my place with this tail?” Nikka wondered as…
