DTMG BILLY X READER

When your son learns how to speak

You were on your table, you were now a music producer, so does Billy, he's in the living room with (b/n), you were just composing a new song for 1D, until you heard
little words at the living room, you walked through the platinum doors, you sighed and held your temple, "Billy, i told you not to let him watch southpar-" "m-m-MA!" Your son waved, you almost dropped your coffee, you walked to your son and Billy, "(b/n), say it again" he heard your words, he faced Billy then, and put his widdle hands on his chest, "Pa!" He said smiling, Billy awed, held him in his arms, "That's right, (b/n), i'm your pa" he patted his head, and he earned a little baby giggle, you kissed Billy's cheek, showing him for being a proud dad.
