As Nikki pleasured herself, David’s warm musky equine cum soaked further into her pants. She moaned and bucked her crotch against her hand.
“This… ooooh! OH! This is incredible!” She panted as she stroked her throbbing clit and soaked pussy.
Overwhelmed, Nikki rolled her face against the couch as she fingered herself. Globs of infectious horse jizz smeared against her bare face. Too enthralled with her lust, she rubbed her cheek further into the warm tingling cum. Her tongue even takes a salty taste.
“I feel so sexy! I have to cum!” She screamed banging away at her snatch hoping for some sexual relief. “These pants are in the way!”
Sliding the pesky pants and her soiled panties, Nikki flopped her bare ass onto the couch unaware of the chestnut brown horse tail extended just above her juicy anus. The cum made a wet goopy noise as she rubbed her jiggling rump into the couch.
Meanwhile, as she fingered her swelling leathery vagina, she played rough with her sensitive nipples. Little did she know or feel among all the erotic sensations, her breasts surged with hormones, growing bigger by the second. Her once delicate B cup boobies were DD’s… then EE… then FF!
“Ohh! Oh c-can’t… b-b-breath! Oooooooh!” She moaned as her blouse buttons gave way. Her massive jugs jiggles and bounced wildly. Lusting for more, she tore the blouse from her and tossed it aside.
Nikki was now naked!
She blissfully groped her titanic tits as feminine juices drooled from her pussy lips. But as more leaked from Nikki’s contorting snatch, it became less human in musk. Rather, as she masturbated her now equine shaped vagina, musky mare juices gushed from her.
Too caught up in her approaching orgasm, Nikki didn’t notice the world had gone mute as her ears lengthened into horse ears before blood filled them.
“It’s getting so warm! I n-need… Oh I have to cum!” She begged with herself as her body prickled with a brown course layer of horse fur.
Nikki moaned loud enough for David in the other room to hear as pleasure over took her from something she didn’t expect to give bliss. She wiggled her toes as she played her pussy like a guitar. But they grew clumpy. Slower. Stiffer. Then impossible to move as her toes morphed into hooves.
The infection had ravaged Nikki’s body. Proving to be highly susceptible to the infection, the only human part of her was her moaning pleasured face. The rest of her was now a highly infectious mare mutant.
“Oh! Oh! Yes! Please Oh… Ohhhh…aaaaaaAAAAAAAH!” She screamed as her body convulsed in an earth shatter orgasm.
As rubbed her abused mare clit as her pussy flared out erupting like a messy musky geyser. Feminine mare love juices splattered out in a cone from her snatch. The couch reeked of both David and Nikki’s infectious sexes.
“Ooh naaaah mmmph! Neeeiiiigh!” Nikki whimpered as her face pushed out from her into a horse snout.
As the last of her changed, she glanced down at her sexy mare body. She sat there in ecstasy after having the best orgasm of her life, just petting her numb clit. Her pussy flared out like a horse in season.
The infection had taken over. Her once innocent nature was gone. She had nothing to say about her sudden erotic transformation, except… “I wonder how horse cock feels?”
Sitting up from the couch, David’s horse cum clung to her back and ass as it dried on. She got up and put a hand to her large come-hither hips. She flicked her tail up as she looked herself over in a full-length mirror.
“I look sexy as fuck! David’s gonna love me!”
Nikki could hear faint panting on her phone. “Oh… how sexy do you look, Nikki?” asked Emily.
She picked up the phone. “Go enjoy my ex’s slimy tongue, Chicken Wings. I’ve got stud cock to fuck.” She hung up and swayed into David’s.
Sex on the mind, this is only gonna end one way.
