A teen craves for his dad, keeps fantasizing being embraced by him while masturbating. He even lies that he's already with a man to encourage / lure his dad to hold him.
≫➤ Actually incest doesn't happen yet, whole story is just his fantasy but the last page clues that his fantasy may be gonna come true. It's still open end thou.
IMO As a daddy's boy, it sounds more realistic if he calls out 'Daddy' instead of 'Father'.
