Nine months later Ginny and Harriet gave birth on the same day. Ginny's girl was red headed with Harriet's green eyes. Harriet's girl slithered out of her, with black hair and green eyes as well and a snake body from the waist down. She drank eagerly from Harriet's swollen breasts, then fell asleep in Nagini's coiled body. Nagini, who had become Harriet's trusted friend in the past months, had shared the bed with the pregnant girls, always watching over them. They talked through Parselmouth, a skill that Harriet never lost and that Ginny was quickly gaining. It helped that Ginny could not get enough of Harriet's old dick, still attached and functional on Nagini, who was declared Godmother to both babies.
Harriet had left Hogwarts with highest marks on all her NEWT classes, as had Hermione by the way. A spot was ready for her to become an Auror, but Harriet first tried and signed with the Holyhead Harpies, an all female Quidditch team, while Ginny finished her last year. She got pregnant again, this time from Dumbledore's horcrux. It seemed like Dumbledore's soul was perfectly happy in his dildo like state and Harriet wondered if part of that soul was split off into her unborn child.
When Ginny finally finished school the stick shot his load in her as well on her first night back and after that they knew the horcrux was no more. Two more girls were born and both had all the smarts of Dumbledore.
They wanted a big family and Nagini fathered the next set of girls, apparently boys were not an option. Harriet's was a fully human now, but Ginny's was another naga.
Both Ginny and Harriet played a couple of years for the Harpies, winning two championships, until Ginny started a job with the Daily Prophet and Harriet followed her dream of being an Auror.
She had one more child, fathered by Snape and it would be the only boy in an all female household. But that's a whole different story by itself...
