The story is amazing! The bond between Gracie and John, just after one night is written very nicely.
I have a serious doubt that the three girls could be John's own daughters. Well, they look same as Gracie, but there was one line by one of the girls, the redhead, that her Grandfather kicked her mom out when he found out she was pregnant.
During John's and Gracie's sex scene, there was only one option of creampie. So this raises a question. Is the triplets actually John's children?
Anyway, will you be uploading future chapters here on itch.io too?
