Ty smiled- Abayomi seemed so glad to have changed, and he thought he had been handsome as a man and she was now beautiful as a woman. He made a quick wish that she would know about his virus and who he was, and then stepped through the window into Abayomi's room.
Between her newfound knowledge of who Ty was and her inflating libido, Abayomi felt a surge of arousal race through her as Ty came into her room, and when he stepped forward to kiss her she kissed back eagerly. "You know what I want to do to you?" Ty asked.
"No, tell me," Abayomi replied, sure she'd find it hot.
"I wanna fuck you up and make you pregnant with my child, and then I want the virus inside you to turn me into a beautiful woman just like you," Ty told her.
"Let's do that," Abayomi agreed, and helped Ty undress. She tore off his T-shirt, he undid his jeans, and she helped him out of his boxers. He stepped out of his male clothes like a snake shedding its skin, never to return to his old self, and his erection rubbed on her stomach. She spread her legs for him, and felt him push her to the floor, shoving himself inside her.
Ty gasped and Abayomi moaned as he breached her, and slowly he pulled back and started thrusting in and out of her eagerly. "I already feel weird," he breathed, knowing the contact between Abayomi and him had been more than enough for the virus to infect him.
"It's cause you're starting to change," Abayomi smiled. "I can already see your face looks more girlish!" Ty blushed at the thought, and his hips pounded into her faster. A warmth built up in his chest, and he whimpered in a higher-pitched voice as Abayomi's fingers rubbed at it. "I think your boobs are forming," she giggled, and when she pinched his nipples he moaned in a girlish voice.
"Fuck, I'm close!" Ty gasped.
"Cum for me! Fill me up while you still can!" Abayomi encouraged him.
"Aaaahhhn!~" Ty moaned, his voice cracking and his balls pressing against Abayomi and spasming as he finished inside her. Now one of their goals in having sex was accomplished- inside Abayomi Ty's semen, still unaffected by the changes, seeped into her womb, finding a fertile egg that the seed inside it could fertilize and start to develop into offspring.
Meanwhile, Ty could feel his penis slowly receding into its feminine counterpart. He withdrew his shrunken member and a few more jets of his seed messily shot from it onto Abayomi's tits and stomach. Now he could look down at himself, he realized his crotch was basically the only male part of him by now.
A twinge inside him told him that was about to change too. His balls tugged up inside him and he felt them reshaping into ovaries around a womb, his scrotum tucking inwards and a vaginal opening forming down the middle. And the last of his penis transformed too, as he felt its slit seal up so he couldn't ejaculate from it anymore and it shrank into a tiny nub between his legs.
Abayomi leaned up and kissed her. "You're a really pretty girl, Ty," she assured her.
