As he was coordinating the evacuation, the ship's captain was dive bombed by Diana and Heather. The harpies gripped his shoulders with their talons and shoved their cock down his throat. Additionally, Diana reached back and grabbed the nearest crew member, a dark skinned woman, and pulled her mouth tight against their asshole. It only took two quick thrusts before they emptied their balls into the captain's stomach and forced the accompanying egg past their other victim's lips.
Even as his stomach was being pumped full of cum the captain began changing. His skin turned pitch black and took on the rubbery sheen of latex. This new skin then tightened, compressing his muscular, six-foot-two body into a slim and feminine five foot tall form, all of the excess mass from the transformation used to fill out his basketball sized breasts and ass. The latex texture of his skin then spread over his hair, turning it a bright crimson as it cascaded down to his back, a pair of black vulpine ears parting the rubbery strands. His growing hair stopped just above the nine rubbery flaps that had emerged from his tailbone. The cum from the harpies that had begun to bloat his stomach was quickly forced down into one of these flaps, which began to stretch out into a rubbery fox tail as it was filled with seed. By the time all of his lovers' cum was inside him, the captain's first tail was stretched to the point you could see the pearly fluid slosh about inside it, while a second was half full.
At the same time as the captain's transformation, the woman being held by Diana felt the egg in her mouth break, its tainted insides pouring down her throat. The first thing that happened was her tongue thickening into a cock before growing out past her lips and entering Diana and Heather's rectum. The conjoined harpy let out a pair of squawks at the unexpected penetration, the added pressure on their prostate helping fill the soon-to-be latex kitsune with even more seed. The transforming woman moaned around her cock-tongue, now the length and thickness of a one litre bottle, as four more cocks emerged from her body. These cock were on her chest, two replacing her nipples with two more growing further down her torso. These two lower cock were raised up by a new pair of breasts that grew to match her original pair in size before all four exploded out of her shirt. Each tit stopped growing when they were nearly beach ball sized, the four of them covering her entire torso. The dicknipples they sported were no less extreme, three foot long horsecocks as thicker than both of their owners fists put together. These weren't the last cocks to grow on her however as five fleshy tails, each one tipped with six inches of girldick, emerged from over the waistband of her uniform.
Once the crew mate mutation was finished all ten of her cocks came, spreading mutating cum throughout the crowd. All of this happened within a few seconds of Diana and Heather's arrival, spreading an immediate panic throughout the crowd. Those already on the lifeboats attempted to launch them before any current or soon-to-be mutants got on them. Some lifeboats successfully landed in the water while others dumped their riders into the sea, either way their efforts to escape were rendered invalid when the giant kraken woman emerged from beneath the boat and began snatching people with her lusty tentacles. One woman who was struggling to stay afloat got consumed by one of the kraken's vagina tentacles only to be placed back on the ship's deck as a cock-naga with dozens of tentacle cocks for hair. Another woman was snatched up alongside her boyfriend by a cock tentacle and fed cum until they fused into a two headed herm centaur with a horsecock between both their front and back legs.
This mess was only worsened when a horde of mutants emerged from the lower decks, led by a familiar centipede-taur.
"Tai! There you are!" Lei pushed through the crowd to get to her husband, the man too shocked at what had become of his wife to make any attempts at fleeing. Lei scooped her husband into her upper six arms and pulled him into a deep kiss, her twin cock-tongues firing weak shots of precum into the man's mouth.
Tai had already resolved when the outbreak was first announced to let Lei mutate him if she had been infected and began using his own tongue to pleasure the shafts in his mouth, something that became easier as his youth was restored to him. Unlike with Lei, who had the body of a (very youthful) thirty to forty year old, Tai's transformation brought him all the way back to his early twenties, though just like his wife his form didn't match what he actually looked like at that age. Tai's new form after the first part of his transformation was what one might generously call "androgynous" and might less generously call "girly." His hips were wide and his shoulders were narrow, he had dainty limbs but a big ass, and his hair was shoulder length and glossy black. His already ill-fitting clothes were quickly torn apart by the fuzzy moth wings, extra pair of chitinous arms and foot-long cock that grew on his body, accompanied by antennae and a watermelon sized nut sack that concealed a developing vagina.
As Tai made out with her herm femboy moth husband, more and more people were succumbing to mutation. Several groups of people tried futilely to escape the horde, one of which was stopped when a pile of pink slime dropped from a vent above them before reforming into Cafly. Much like the three friends that made up the fourteen foot tall slime girl, the group inside them consisted of three women. One was a short, pale skinned woman with dyed blue hair and the other two were a pair of red headed twin sisters. Since they were already enveloped in the slimy embrace of Cafly they began to immediately transform, the two red-haired women were pulled into the blue haired one’s crotch as their bodies turned into cocks with their heads replacing the glans. The blue haired woman’s body from the neck down then shrank away, leaving her as nothing but a head with two nubby feet attached to either side. Finally, two pairs of watermelon sized balls grew between the woman’s feet, which began pumping cum through her human-sized living cocks as the three women came into the body of their slimy captor.
Catherine, not wanting to get trapped on the cock of a mutant again, decided to make a break for it towards the stern of the ship. As she ran another woman in the crew uniform was beside her, having gotten the same idea.
“Hey that’s Johanne! That bitch pushed Sam into a mutant and ran off.” Sasha was peeking out from under Catherine’s skirt at the woman, and began rubbing the massive cock between her legs as she planned to get back at her coworker. Once she was just about to cum she darted out in front of Johanne and unleashed her orgasm right in her face.
Startled by the surprise facial, Joanne began to stumble. When her body began to grow taller and her eyes fused together she fully lost her balance and fell to the ground. Her body added inch after inch while a second pair of arms formed below her originals and a third leg grew in between her normal two, her vagina being duplicated into both crotches. Each of her vaginas were then joined by a pair of foot long cocks as well as a proportional pair of balls. At this point her growth stopped with her being ten feet tall. Her sprawled out form acted as a barrier to the mutants chasing Catherine, giving her a fighting chance of getting away. However, this chance slipped through her grasp when a slug woman crawled up from the lower decks just in front of her.
"Catherine! Where's your mother? I really need to see her." Even as she spoke the mutant that was Catherine's father crawled forwards on the slug foot that had replaced her legs, faster than you might expect but still slow enough that Catherine and Jane had been able to easily escape earlier. Unfortunately there was a horde of mutants at their back this time and the waving tentacle cocks that protruded from the back of the mutant before them would make it difficult to go around. Unfortunately for Catherine, her mother ensured that she wouldn't even be able to attempt evasion.
"I'm right here Honey! Under her skirt!" As June called out her horsecock grew fully erect and tented Catherine's skirt, causing her to stumble right into the grasping tentacles of her father.
Immediately Catherine was flipped upside-down and pulled against the slug woman, her face pressed into the slimy tissue of her father's lower body. Her skirt flipped over to reveal what had become of her mother, her mutated parents sharing a passionate gaze.
"June! Let me get you off so we can catch up."
"No Honey, I'm the only thing stopping our daughter from mutating!"
