Two lovers walked down a sidewalk. One of them was a twenty five year old reasonably handsome asian guy with an athletic build named Darin and the the other was a twenty six year old reasonably attractive if not exactly thin brunette named Tasha. Both of them were dressed for the slight evening chill after a nice night at the coffee shop discussing their personal favorite books. As they walked down the street they went by a loud bar where a party of some sort was happening and was spilling into the streets. As they walked by a redhead in a miniskirt, tube top and too much makeup stumbled into Tasha and gave her a peck off the cheek.
"Get lost!" Darin said to her as she pushed her off. With that their pace quickened to clear the group. Even so Darin noticed something odd about the redhead. Maybe it was her chest or her face. He only got a moment's glance and could not make much out about her. The rest of the girls in the crowd similarly seemed off, as did the guys. Especially since the party's crowd was similarly off. There was also a smell that he could not define besides being vaguely salty and oddly enticing.
"You feeling alright?" Darin asked..
"Yes, i'm fine. Bunch-of-wierdos..." She muttered
In any case they continued for the next few blocks to Tasha's apartment. As they approached Tasha's mood shifted from annoyed at the situation to bubbly. When they arrived at her apartment building Darin had the odd impression that she was now a bit taller.
"Hey." Tasha said in a voice that was now a bit off, a bit more girly. "Why don't you come up for a night cap?"
Darin was uncertain of it for a few seconds, but eventually decided to roll with it. "Why not?"
With that they came upstairs to Tasha's flat where she made him some hot chocolate. When he got his mug he noticed that she had turquoise nails now. He also began to pick up on that odd salty smell. They exchanged some conversation for a few minutes, which had been gotten increasingly suggestive before he felt the need to go to the bathroom. As he washed his hands he noticed in the mirror that his hair was a bit longer than it was. As were his eyelashes. It was strange. Even so when he returned to the living room he found it empty.
"Darin," Tasha's voice came from her bedroom "there's something I'd like to show you."
"Okay." He said as he walked in. When he did he found her lying across the bed suggestively, her pants on the floor. He was also hit by a wave of that smell.
"Oh my!" He said suprised by it all.
"All things considered, we've both had a good day." She said. "I think we should end it on a high note. C'mon here!"
Despite this being a surprise Darin decided to go along with it. He came in to the bed, she crawled up him and kissed him on the lips. They then embraced and Tasha's hand gave him a playful honk in his groin. It felt so good, better than he remembered the last time being. Even so as he did so he noticed something odd with her chest. As he put his chest over it rather than feeling a soft pair of breasts pressed against him, he felt a warm flat torso. When his hands went searching for breast he found none.
Despite a desire to keep going the oddness of this situation made him back up to examine her. He saw that her figure which was once a bit on the chunky side had slimmed out a fair bit and was now more akin to a model or a swimmer and she was completely flat chested.
“Tasha, what happened to you boobs?”
“Oh?” She said as she looked down at her body. “Well this a surprise.” She ran her hands over her flat chest. “Even, so I kind of like it. Don’t you?”
Darin paused for a moment. “Actually, yes.”
“And I love what you’ve done with your hair.”
“What?”
She giggled. “Turn around!” Darin did so and looked into the mirror. He saw that his hair had grown out a fair bit and now thick black locks tumbled nearly to his shoulders. He felt it and tugged at it, admiring it’s luster and sheen. He liked how it looked, it looked, pretty. Also were his eyelashes that long and his lips that full the last time he checked on them?
“What’s happening?” He said?
“I don’t know,” She said lustily as she gave him a peck on the cheek “but I like it. Now give me a kiss.” Their lips met for a long open mouth kiss. When they pulled apart she gave him a grin. “Now do that again, but a little lower.” Darin went down, lowered her panties and he began to eat. His lips sucking and his tongue probing her reaches as Tasha gave giggles of pleasure. Oddly enough he felt like it too. Then he noticed things begin to change. Her lips began to feel tighter and tighter and a point began to grow. Her moans gave it his attention and he focused in on it. It started out like a pea, then became more like a mini carrot, then a cocktail sausage and then finally it inflated out to a hotdog size, filling his mouth before unleashing into it a tidal wave of hot salty liquid as Tasha exalted in pleasure. At the same moment Darin climaxed as well. He then withdrew his mouth and looked up into Tasha’s grinning face and basked in the radiance of afterglow.
Then he looked down at her… no, HIS Crotch.
He saw that Tasha was now sporting an eight inch cock dripping with light pink cum. He pushed it upwards and saw the last faintest traces of Tasha’s vagina close up into a soft sack, which soon filled out with a pair of balls. Darin continued his examination in fascination while Tasha gave little giggles of joy. He also noticed that his hands were now a lot slimmer, more delicate and sported perfect nails.
“I can’t believe it.” Darin said. Then he put his hands to his mouth. “Is that my voice! I sound like a girl.”
“And you look like one.” Tasha Said as he pivoted his head to face the mirror again. Darin soon saw his reflection. His body now had the same slim figure that Tasha did, even if his butt popped out. He also noticed that his face was now decidedly female, with his lips glossed, his eyes shadowed, his lashes long and his skin several shades lighter. Tasha's makeup had taken on a similar quality. He'd lost all his body hair. He definitely looked remarkably female, save of course for the lack of breast and dripping dick.
“Don’t don’t worry about that” Tasha said as he pointed down at his crotch. “You’re still a man in all that counts.”
“So are you.”
“Yeah, and I think I like it.” Tasha said.
“You and me both.” Darin said. “You know I wonder how I’d look in one of your dresses.”
“Like the prettiest little ladyman on the planet.” Tasha said confidently “Watch out world! Daria’s on the prowl and hungry for cock!”
“Daria…I like that.” With that visions went through his mind. Tasha and Daria finding hot studs and lovely ladies to kiss, suck, grind and fuck and watching as they turned into more sexy fembois just like them that they'd screw and be screwed by. “Even so,” he said as he presented his Virgin Ass to Tasha, “I’d also like that sexy dick of yours shoved right here!”
Tasha ablidged and dove in, beginning a night of consummation to celebrate their new lives. Around the world others got infected and began their change into pretty fembois.
