For weeks she'd been sneaking in her father's room after he had masturbated with the purpose of lapping up his expensed cum while he showered and he had learned of it sometime and now she could not fathom how she could be, as he had put it, not in trouble. She spent the day at high school staring blankly at air and wall and wishing she had there a good friend in which she could confide entirely and ask for advice but she had none and so she came home crushed and almost fainted when her father entered the living room for she felt as if he was going to announce to her some terrible fate of deportation of the family home and swearing he would forget about her entirely after emancipating her in law where her behavior would be exposed dissected and registered and she would suffer a shame from which she would never recover.
Instead of that he was naked and said:
Show me how you do it.
What?
I want to see you do it.
She felt so terrible that she took very little notice of his own indecent exposure. At present he was saintly and she wicked for all she could understand and no thought of challenge entered her mind though she did feel stirred inside but could not yet interpret that feeling. She undressed and did not cover her breasts with her arms as she normally would for she was entirely focused on the task at hand which was to show Dad how she did it. Removed from her clothing she got to the ground on all fours and as it had been tiled rather than carpeted her knees and elbows would soon redden but she paid it no mind as lubrication in a pavlovian fashion started coating her pussy lips and she reached for it and inserted two fingers in it.
Dad stood there watching and if he said something she did not hear and when he went to stroke the shaft of his now fully erect penis she did not perceive any movement. She looked up and was struck with the image of her father towering above her and his dick had indeed become a great and powerful thing now and the world around them faded and only the primordial tool of conception remained surging through the blur its head glistening and its body pulsating with the friction of the hand.
