Ty decided to start with the omniscience option. In her mind's eye, she went to a young couple somewhere in the US. A few minutes ago, they had been a man called Caleb and a woman called Jessie, but naturally that wasn't the case anymore. Caleb was still adapting to the soft breasts that now hung from her chest and the moistness and gaping emptiness between her legs, while Jessie was still enthralled by his new, more muscular build and the erection that protruded from between his legs.
Not surprisingly, the two of them practically leapt at each other. Jessie carefully pushed Caleb down and kissed her, rubbing his head against her stomach before moving it into position. "Is this OK?" he asked in his deeper baritone.
"Yeah, do it," replied Caleb breathlessly in her feminized voice, and Jessie pushed his shaft inside her eagerly. He started thrusting eagerly in and out, his balls slapping her body with each thrust, amazed at the intensity of his masculine form's arousal.
Caleb, on the other hand, was transfixed by the feminine form's pleasure- her body had never felt so stimulated and given her such a rush of joy. When his hands went to her breasts and carefully cupped and pinched at them, the stimulation amplified and she moaned uncontrollably, her body clinging to him.
It wasn't long before their bodies' instincts took over as they approached orgasm. They pressed themselves against one another as close as possible, until at last Jessie grunted and felt his cum shoot into Caleb's pussy. The warm liquid entering her and his shaft spasming pushed Caleb over the edge, and she moaned eagerly as she came around him. His sperm flowed up into her and fertilized an ovum that her body had produced as her testicles had changed into ovaries.
Seeing all this was kinda hot to Ty- these two had only minutes earlier had the exact opposite bodies and instincts, and they'd embraced their new sexes as naturally as if they'd been born into them. She wondered what to look at or do next...
