Ruining My Puppy After Edging His Two Cocks

Description: This locktober, i played a mischievous game with my pathetic little puppy. i put a strap-on right over his real cock and let him only stroke the strap-on when i say so while i stroke both cock, either cock, or neither cock as i please. i wondered, will stroking the phantom cock make him cum hard? spoiler alert: he erupted while fapping with the strap-on and i wasn't stimulating his real cock at all. then it was back in the cage for the poor ruined puppy.
