Suddenly as Heather tried bearing down three enormous bulges swelled, as the front bulge swelled thicker it elongated as a hole peeled open and rolled into a ring as the seal for it, then its width swelled to twice the thickness as the dragon cock grew to adult size. Then the back bulges stretched down and out for about eight minutes before the scrotum settled. They slumped down to the ground to rest for a couple hours before their new massive testicles dropped.
Suddenly mid rest, Heather and Kim's heads and necks shot at lightning speeds back into their shared body before Johns belly exploded to the size of a full term with a dozen babies pregnancy, after which, two massive eggs the size of one hundred eighteen year old female dragons splashed onto the ground before searing heat like acid was felt and Johns female opening disappeared forever.
John got the instinct to stand before his massive house sized balls dropped into his nutsack stretching it even wider, with audible sloshing as several million gallons of cum and sperm splashed roiled and fermented in the volcanic heat of his massive nuts. He laid down to rest feeling the massive weight of his new dragon testicles under him.
As he rested, his neck grew longer and thicker as his head grew equal in size. He then felt the urge to pee, and dug a hole to piss into, he relieved his bladder into the hole before his instincts told him to blast it with fire.
Doing so he felt his instincts tell him he and his ready to hatch females were cured of the virus.
As John turned to go protect the eggs he birthed before losing his female opening, he heard a massively loud CRACK CRUNCH, John sprinted for the temporary nest, laying down while watching his mates hatch before him.
As Heather and Kim made the first hole in their eggshells a literal river of amniotic fluid poured from the eggs. Now no longer floating, Heather and Kim stood and broke open their eggs with enough force to equal a giants club levelling a human house in one swing of their strong necks. Heather and Kim tired and hungry drank from each others crotch breasts to fill their stomachs and regain their strength after the ordeal of their physical separation into individual entities, the explosively rapid production of their individual dragoness bodies, John laying their eggs and their subsequent hatching and resultant re-entering into the world
They lay against Johns side, laying their heads against the grass, all the while, John the dragon alpha keeps watch protecting his females, disintegrating would be bounty hunters and zoo keepers into heaps of ash while Heather and Kim sleep.
