Her perverted friend, Narika

Heather hurried through the hallways, listening closely for anyone that she could get fucked by. An ache between her legs reminded Heather that she still hadn't had a dick inside her and her female parts were just as needy as her male ones. It was something she meant to amend as soon as possible and she had just the person for it.

Narika was the one girl in the bunker she knew for a fact was horribly perverted, even before the virus had hit. Ever since she had caught the black haired girl masturbating over some weird Japanese porn, Narika had been very transparent with her about what she was into. Heather had never felt the same way, but now she was looking forward to making her friend's idle imaginings real.

Knocking on a door, Heather waited. It only took a moment for her to hear footsteps approaching the door. She didn't bother to take a sexy pose, knowing what would surely happen once the door opened. A second later, it swung open, revealing Narika. She was pretty, sporting pale skin with average breasts on her otherwise thin frame. Her straight black hair fell in a long sheet down her back, two stray locks framing her cute face. She looked steadily at Heather for a moment before she realized what she was seeing.

"Hey Narika. What to fuck me?" Heather asked, candidly, her hard shaft pointing at the pale girl's face. Narika's eyes went wide and, after a quick glance around, pulled the futa inside with a flushed face. She was wearing a light pair of track pants and a t-shirt, both of which she immediately stripped out of, leaving her in her underwear as she waved her meager ass at Heather, already on all fours.

"Yes Heather, please fuck me. I want to get fucked by you. Look how wet I already am for you," the lusty woman said, tracing the outline of her labia through her green panties. A wet patch was already appearing on the thin fabric. Heather drooled at the sight, her dripping cock aching to be put to use, but the wetness between her own legs was more pressing for the moment.

"That's not what I asked, Narika. I asked if you wanted to fuck me. With your own cock, of course," the brunette futa said, carefully watching her friend's face as it morphed from helpless desire to slight confusion and hope.

"You mean I can..."

"That's right, just come here and I'll give you a cock of your own to fuck me with. You think you're wet, you have no idea how badly I need it." Narika wasted no time hurrying over, standing face to face with Heather.

"How can I get a dick like that?" she asked, very clearly hopeful. Heather reached down to her own member and scooped up the precum that was dripping out of it. She raised her messy hand up to Narika's face, holding it inches away.

"You drink my cum and soon you'll have a big sexy shaft of your own." Narika barely hesitated in slurping on Heather's dripping fingers, eyes sliding shut as she relished the taste. She sucked every drop from her friend's digits and continued to suckle on them afterwards, only stopping once she felt a twinging between her legs.

Narika and Heather looked down to see the black-haired girl's panties bulging obscenely, stretched by the growing lump of cockflesh inside. It was flaccid as it grew, bunched up in Narika's underwear, until Heather's hand dropped down and traced the bulge, still wet with spit. Narika let out a muffled moan as new sensation rushed through her, her blood flowing down into the new organ. The bulge in her panties grew and straightened, extending into a towering futanari dick.

"Yeah, that's more like it. Come on you hung bitch, shove it up this drooling cunt," Heather moaned, showing her friend her own plump, fuckable butt. The transforming black-haired woman once again showed no hesitation, lining up her new shaft and pushing the whole length into the drooling snatch in front of her. The feeling was heavenly, the tunnel tight and rippling as Heather unconsciously milked the newborn futa for her cum. Narika barely held back, but was pushed to the edge as Heather began fucking herself on the other woman.

"YEEESSSSSSSS," the brunette hissed, pushed to orgasm at her penetration. Her heavy tits bounce as she thrust her wide hips back to meet the cock filling her up. One hand was rooted to the table to keep her upright, but the other had no qualms about dropping to her dick and stroking it in time with Narika's increasingly rapid thrusts. Still on the tail of her previous climax, Heather came again, cum spewing from her shaft as her cunt squeezed tighter. She heard Narika scream in bliss before the dick in her throbbed and twitched before filling her rippling vagina with hot sperm.

Neither of them could control themselves after that, both futas regressing into fuck machines. Narika's transformation continued, changing her thin frame into a paragon of sexual power. Tits flowed out into rippling and heavy spheres, beautifully sloped on her chest. Her legs reformed, becoming muscled and sleek. Any imperfection faded away as the she completed her transition into a busty, hung futanari woman. In all her many perverse desires, she had never dreamed of such a thing, blowing load after load into her friend's womb, but she wouldn't give it up for anything.

Eventually, Narika, unused to having a cock, pulled out too far and came free of Heather's pussy. The cool air of the room was enough to set her off again, and she collapsed, semen flying in all directions. Heather, more used to the overwhelming bliss of shooting a massive load than her friend, managed to stay mostly upright as she did just that, covering yet another room in her spunk.

"Should have done that...*ngh*...earlier..." she grunted, coaxing every last drop of seed from her balls. "You should go find a nice cock to get fucked by too. It's really good."

"Okay," Narika said faintly from the floor, her mind reeling from her change and her nose filled with the smell of cum. "What about you?" she asked.
