Before Nikka can react, Max let's out a beastly animal bellow. As an excessive amount of hot buck seed baths the doe's pussy, he flops her over and proceeds to fuck her.
Between the animal grunts and Max's body resembling that of a feral buck mutant, Nikka knows her Max is gone. Only the savage horny beast happily seeding his new mate remains.
"Take it! Bare my young," Max shouts as he empties his heavy balls into the doe.
"Oh my strong buck. I am with fawn now. The first of many I will carry for you."
Nikka looks at the two mutants blissfully unaware of the world around them as Max's cock pops from her seeded sex. She isn't sure whether she is jealous or disgusted by the amount of cum her mutant Ex filled the doe with. He had never filled her with so much. But peering down between his legs, Nikka blushed as a pair of softball-sized nuts hung from him.
Nikka moaned as she felt her sex swell and burn with desire. Her doe tail perks up at the sight of the buck's cock and balls; if she were naked, it would be visible to everyone that Nikka's tail is lifted in presentation.
When Nikka realize this terrifying fact, she bolted into the forest as fast and as far as her mutating doe legs can take her.
"Don't run! I'm gonna seed you next!" Max shouts to her.
As her ears sprout out into long furry doe ears, she could hear that Max was chasing her.
"Fuck! He's gonna rape me," Nikka says to herself; feeling her stretching mutating sex drooling to the idea. Speaking of her changing sex, it awkwardly rubbed against not only her thighs, but camel toed as her expanding hips and rump pushed her pants to their limits.
Jumping around a bend, Nikka's eyes widen as her jump carry her 10 feet off a ledge. Luckily for her, her knew deer legs easily make the jump and land safely. However, landing in a leapfrog position, the extra shifting weight tore right through Nikka's pants. As the soaked ruined clothes fell from her huge jiggling furry butt, the cool forest air kissed lovingly at Nikka's swollen fully mutated deer sex. With a low-pitched bellow, Nikka rolls her eyes back as her twat flares open, spilling mutant juices over her ruined clothes and the forest floor. With each orgasmic contraction, Nikka marks the area full of her infectious deer juices. By now she knew Max was on her tail. By now, he had smelled her sex bathing the earth with her scent. She knew she had to run, but she didn't care. She had to enjoy her orgasm. The mutant battling to take over demanded it. Nikka demanded it, even if it meant Max catching her. Fully embracing her mutation, Nikka rips off her shirt, letting her fur covered tits free. With her soaked panties the last to go, Nikka stands on her hands and knees as an even more intense orgasm takes her. From the neck down, Nikka is a doe mutant just like Max's newly seeded mate.
Reaching under herself, Nikka rubs her hoof hand against her sex, resulting in even more doe cum spraying from her. As she does, she could happily feel the rest of her humanity changing; her face pushing out into a snout, and two smaller antlers growing from her forehead.
Nikka is a deer mutant now. A needy mutant, but still herself. Her mind has not left her yet.
"I... I have... to get out of here," she begs with herself.
"Why? Your mate has arrived, " the buck she once called Max said sporting a massive erection. "The answer to all your needs rests between my legs."
Nikka stares longingly at Max's big red buck cock; the doe needs to be mated. It was torturing her to feel so horny and feel no buck atop her.
Without prompting, Nikka's tail arches up, presenting her ass and winking sex.
"My poor doe, your sex needs attention. It needs filling," Max says nearing the poor needy girl. "Let me help."
Without warning, Max's long buck tongue laps up against Nikka's sex. Nikka moans as a pleased-silly stupid smile is plastered over her face as she happily let's Max work her; neither Nikka or her doe side arguing with the oral loving. Pushing her butt into the air and lowering her heaving breasts, Nikka let's Max pleasure her.
After nearly a minute of tongue service, Max stands above his doe. Crouching down, his balls hang beneath his impressive man meat, ready to take Nikka. Watching her buck getting into position, Nikka's body lifts its tail, ready to accept her buck. If she doesn't resist now, she'll be lost to her infection.
Here comes his cock...
