Kat's mother paused for a second, "Oh, yes! How could I have forgotten?" She pulled off her tight mom jeans to reveal a taught slit beneath translucent lacy panties.
Kat looked over the counter as a moment of dizziness hit her. Blinking a few times, she said, "Morning, Jane."
"Morning, Kat," it said.
Looking at the time, her mother said, "Oh, honey, it's almost time for the school bus!"
Kat, without hesitation, got up and put on her backpack. She went up to her mom and kissed her on the cheek.
From below, Jane gurgled, "What about me?"
Kat crouched down in front of her mom. Pulling the front of her panties down, she kissed her 'sister''s lips, sticking her tongue in for a second before pulling back. Then, she rushed out the door to the bus.
Kat's mom smiled and rubbed Dan's 'cheek'.
Dan nuzzled happily against her hand and panties. His mind clouded as she rubbed. He was no longer Dan, but Malorie's little Jane. When her mother and her father had tried for another child, during the ride to the hospital it was somehow absorbed back into her mother. It's soul was absorbed into the only thing it knew, her mother's vagina, which is what she was and would always be.
And she was perfectly content with that.
