While Mark walked out of the house in a horny stupor to go and find some people to turn, his and June's fidelity as forgotten as their genders, her former wife went back upstairs, still naked and returning to hardness thanks to his anticipation of the abhorrent deed he would soon do. Now there was only one male left in the house behind him, and that male was the one most self-assured of his manhood. It would only make it sweeter to take it away.
He came into Dustin's room swiftly, and the teenage boy was stunned by the sight of this handsome man- he looked so unlike the woman who had birthed him he barely made the connection. "Hi, Dusty," he said sultrily.
Dustin winced and looked angry. "Don't call me that," he growled. "It's a girl's name!"
"Well, that's fitting," said June, coming up to the boy and grabbing at his clothes, using his strength to overpower him and undress him as she had in less gross circumstances many times when Dustin was younger. "You always were so stupid and pompous as a boy." He laughed as he saw Dustin's underdeveloped torso. "And for this little," he taunted as he got Dustin naked and saw his small cock.
Dustin felt intense discomfort as June pushed him to his bed, the handsome man pressing his body against Dustin's much less developed one. "Do you know what I'm gonna do to you?" Dustin shook his head, fear in his eyes. "I'm gonna turn you into a girl and fill you with my seed, like I did with Ty and your father," June purred.
"You can't..." Dustin protested weakly.
"I will," June proclaimed victoriously. "And I'm gonna enjoy it a lot. I know how much you hate women, but I'll make you love it."
Their cocks pressed together, and Dustin whimpered as he felt his start to shrink away. June's was so much larger, and he felt his resistance to it start to wear away. "You're never going to get to fill someone up with your cock," he teased, and to his surprise, Dustin felt like having someone fuck him like June was threatening to would feel nicer than that.
June's large hands reached up to Dustin's chest, and pinched his nipples, making him let out a loud moan of pleasure as mammaries started to develop around them. "I bet you want to feel more of that," June grinned, and with his conscious will to resist fading, Dustin had to admit he was right. June rubbed more at the nipples as they swelled up into protruding teats and soft breast flesh sprouted around them, and laughed, "You have nicer tits than anything on your boy's body ever looked, Dusty."
Dusty- that name suddenly felt way more fitting. He slowly came to notice how his figure had feminised too, his hips were wider and his waist slimmer. It all looked nice and girlish, and properly developed. Only a bulge between his legs still looked masculine, and he felt June's cock head brush against it. "Do you want me to castrate you, Dusty?" June breathed.
"Do you want to?" Dusty asked in his higher-pitched voice.
"So fucking much," June replied. "I want to force your body to stop producing sperm and start producing eggs, and your ballsack to open into a pussy so I can breed you."
"Do it, then!" Dusty begged, and at once June pressed against him- and she relinquished her manhood. His testicles moved up inside her and linked up to a womb that formed, converting to a female reproductive system and releasing an egg ready for fertilising. The small nub of a penis he still had finished its shrinkage into a clitoris, and the seam along his scrotum that had formed when his body became male in the womb unsealed itself and formed her vaginal lips. Dusty's body had become totally female.
June smiled and leaned into Dusty, the two of them sharing a kiss as they braced themselves to have sex...
