Kiki and Frankie perked up as they heard a rumbling noise approaching, rattling the windows of the diner. Six motorcycles pulled up in the parking lot, and an equal number of large, burly men in leather jackets stepped off them and sauntered into the restaurant. Kiki, clad in her too-tight shirt, her too-small skirt, and of course her baby-blue bikini, approached the men at the counter.
"What can ah get you hungry boys?" Kiki purred, pressing her huge tits between her arms.
The bikers, sitting on the stools in front of the counter, hooted and whistled, while the head biker ordered six scrambled eggs and bacons, with coffees. Kiki scribbled the order onto a notepad and gave it to Frankie, who cooked up their food, making sure to pour in some of her secret ingredient.
Frankie strolled over to the bikers, handing each of them a plate contaminated with bikini lesbian viruses. "Enjoy your meal, hunks," she said seductively. Kiki and Frankie, licking their lips in anticipation, watched the men, these paragons of masculinity, eat their eggs and bacon and swig their coffees. Though they weren't attracted to the testosterone-filled lugs in the slightest, they were getting horny thinking about what these lugs would become.
The head biker, as the first one to start eating, was the first one to change. As he took a drink from his coffee, he noticed the hair on his arm retracting into his body. Incredulous, he watched his arm become completely hairless before realizing that his whole body was changing. His beard sunk into his chin, his limbs became less muscular and more shapely, and his waist started to narrow. The head biker yelped in fear and his entourage turned towards him - and couldn't believe what they were seeing. His hairy, muscular chest smoothed and shrank into a feminine, yet toned torso. Gone were his tree trunk-like limbs - they had been replaced with long, beautiful arms and legs fitting of a supermodel. His butt grew into two round perky bubbles, tearing his pants. His face, previously the face of a gruff man, morphed into a beautiful woman's, and his closely-cut black hair lengthened into platinum blonde locks that reached to the small of his back. Her lips swelled into dick-sucking sausages, coated with sky-blue lipstick.
The newly minted bimbo moaned and rubbed her chest as two budding breasts grew out from underneath her nipples, ending as perfectly shaped double-D tits that popped her leather jacket wide open. Her undershirt and underwear shrank into a blue bikini, the same color as her lips, as the woman ripped off her shredded pants so that she could rub her new puffy slit. The former biker was now a lusty lesbian, clad only in her leather jacket and her skin-tight bikini that left nothing to the imagination.
The five other bikers watched aghast as their leader turned into a masturbating beach bimbo. They jumped up and ran for the door, but it was too late - Frankie had already locked them inside. Kiki hopped over the counter, and with Frankie and the newly-turned head biker, the three cornered the frightened men against the wall. It was too late for the bikers - the corrupted milk in their food had already infected them. Heat started to build up in their bodies as they groaned, their body hair shrinking back into their skin, their bones and muscles reshaping into more feminine forms.
Frankie pressed her freckled F-cups against one of the changing bikers, her fat, dripping nipples visible through her wet apron. The man tried to push her off, but Frankie planted a big red kiss onto his lips and shoved one of her nipples into his mouth. She squeezed her breast, and a torrent of milk shot out of her teat, filling the man's gullet with the infectious liquid. F-cup breasts ballooned from his chest and his figure became more and more curvaceous. His brown hair expanded into a fiery red mane, and his lips puffed up and turned ruby-red. His skin, formerly tanned and wrinkled from years of biking in the sun, became paler and smoother, and freckles appeared on his cheeks and boobs. And of course, his clothes molded themselves into a skimpy sky-blue bikini, leaving him with an open leather jacket and a baggy pair of pants, which were both quickly discarded. Where once stood a proud motorcycle gang member now knelt an identical copy of Frankie, sucking manically at the real Frankie's teat and leaving lipstick marks all over it.
Meanwhile, Kiki and the converted head biker grabbed the four other bikers in a group hug and whipped off their clothes, leaving the men in only their shirts and boxers. The girls grinned as they massaged the bikers through their changes, rubbing their swelling breasts and butts, and stroking their shrinking cocks through their new bikini bottoms as they inverted into vaginas. Moans filled the air as the new women grinded against each other and slipped their hands down each others' bikinis, their minds reshaping to accommodate their new bodies.
Her work done, Kiki stepped back and sat on one of the stools to admire the fruits of her labor, but the transformed girls continued to escalate their orgy. The two Frankies joined in, and soon the diner rocked with lewd gasps and screams as seven bikini bitches fucked each others' brains out. Watching the mass of blissful flesh, Kiki couldn't resist spreading her legs and stroking herself through her bikini. She pulled out her phone and recorded the orgy to show Lindsey later.
